This guide is outdated and a newer version if offered. Please visit How to root a T-Mobile G1 and myTouch 3G.
I first wrote this guide several months ago, but decided not to post it. After all the cupcake builds were released and people kept asking for help with upgrading, I decided to touch it up and put it out in the open. If you are interested in rooting your phone and installing one of the latest cupcake builds, please read the entire guide before getting started.
If you are nervous about upgrading or want more information on the pros/cons read our article about the different flavors of Android.
This article serves one purpose: demonstrating the easiest method possible to root your Android device. It is currently intended for the T-Mobile G1 and will be updated when other hardware becomes available. If you do not know what root access is, then you most likely should not attempt to modify your phone. Having a rooted phone is mostly for power users.
Preparing Your Phone For Root – Important Disclaimers
Before we begin to root your phone, let’s cover a few basics.
This guide is intended for US phones. If you are in a country other than the United States, please visit the xda-developers forums for more information on rooting your Android device.
If you do not read and follow instructions, you will have trouble. We are trying to make this guide as fool proof as possible, but if you do not follow instructions, you will have problems. I suggest reading the entire guide before you start. This way you can become familiar with the entire process. Thankfully, most upgrade problems can be resolved by flashing the RC29 downgrade and starting over.
Make sure your battery is fully charged. We do not want your phone to die out in the middle of an upgrade flash. Go plug it in now while you read the rest of this guide.
Set aside at least 60 minutes to root your phone. The entire process can be completed in about 30 minutes, but I suggest you plan on it taking longer. We do not want you to get half-way through and then stop. If you start the root process and do not complete it, you might be unable to use your device and make phone calls.
If you install a non T-Mobile build of Android, you will be missing T-Mobile apps like MyFaves. You can still update your MyFaves online, but will be missing the app for now. If this is a problem for you, then do not upgrade. Also absent from the Android Developer Phone builds are several of the messaging clients like MSN, Yahoo, and AIM. If you need these apps, there are many replacements available in the market.
A WiFi connection will greatly reduce the total time required and I highly suggest it. You will be downloading several files with some as large as 40MB. Connect to a WiFi network when possible. You could attempt this over 2G/3G but I do not recommend it.
The first time you root your phone, all data will be wiped. Any data you want to keep must first be backed up before you begin. Most of the important information on your phone is synced with Google, but there are other things you might want to backup. Call logs, SMS history, and phone settings are the most commonly backed up items. Thankfully, there are several applications in the Android Market that can backup most data on your phone. MyBackup Pro from Rerware allows you to backup your data to your SD card or online.
Part of the root process requires you to format your SD card. After you have backed up data to your SD card, be sure to copy it all over to your PC before formatting. If you have an extra microSDHC card, I suggest using the spare for the root process. Also note it takes several minutes to format your micro SD card to the FAT32 file system, so I suggest using the smallest sized card to speed up the process.
After you root your phone, you will not receive system updates from T-Mobile. Part of the root process blocks T-Mobile from applying updates to your phone. This is done on purpose to prevent a future update from removing root access. The good thing is you can manually update your phone to a new custom version of the operating system. T-Mobile tends to roll out new updates over the span of several days, but when you have root you can apply the update as soon as its available. This update process for some root users has been simplified with the application JF Updater. See the end of this article for more information on keeping your phone up to date.
If you run non supported software, T-Mobile will not offer technical support for you. This can be a make or break issue for some people. Instead of turning to T-Mobile when you have problems, you will turn to the community for help. There are many ongoing efforts in the community to help people and most questions can easily be answered via Twitter or several Android forums. You can of course, return to the official T-Mobile version of Android whenever you choose.
Part 1. Downgrade Your Phone to RC29.
Before we begin, let’s check the current build of Android you are running. From the home screen, press the Menu button and select “Settings”. From the settings menu, scroll to the bottom and click “About Phone”. At the bottom of the about screen you will find the “Build Number”. Look for the part that says “RC##”. The numbers after RC indicate the release canidate you have installed. If you have RC30 and above, you will need to downgrade back to RC29. The purpose of this downgrade is to exploit a security hole that existed before RC30 was released.
In order to apply updates to your phone, we must first format your micro SD card to the FAT32 file system. As noted above, when you format your SD card, it will erase all data. Most micro SDHC cards are already formatted for FAT32, but some are FAT16 and I suggest doing it again if you are not sure. Instructions for Windows users:
- Hook your phone up to your PC using a USB cable.
- Click the notification on your phone that says “USB Connected”. Select the “Mount” option.
- Once the device is mounted, you will see a removable disk show up on your computer. Right click the device and select Format.
- Pick FAT32 for the file system and click start. Do not perform a quick format.
- When the format is complete, you can disconnect your phone by clicking “safely remove hardware” like any other USB device.
Now that your SD card is formatted, we can start the root process. For this guide we will be using the root application created by Mike Moussa. His app simplifies the process by including download links to the required files you will need. It also scripts some of the commands to prevent you from making typing errors.
Download the root app here: http://www.androidactivity.com/root/root.apk
You can either download the file on your PC or directly to your phone(I suggest phone). Before we can install the file, we need to tell your phone to allow non-Market applications.
- From the home screen, press “Menu”.
- Go to “Settings” first then “Application Settings”.
- Check the box that says “Unknown sources”.
Now that we can install non-Market applications, we need to find the file on your phone and launch it. If you are in the Android browser, you can go to menu > more > downloads. If you have a file manager like Linda installed it should be located in “/sdcard/download”. Click the file called “root.apk” and hit install.
Update: Some users have reported the DREAIMG.nbh file gets corrupted when downloading over 3G/Edge. To avoid this just download the file to your PC and then copy it to the SD card.
When the root application is installed, launch it from your application tray. Click on “Step1: Download NBH file” to start the first download. This file “DREAIMG.nbh” is what will downgrade your phone back to RC29. Wait for the download to finish, then complete the following steps.
- Power off your phone.
- Holding down the camera button, power the phone back on.
- Wait for the bootloader to come up all the way, and press the Power button to begin the update.
- When the first part completes it will prompt you to hit the action key to continue. The trackball is the action key.
- Once the update is finished, you can reboot your phone by pressing TALK+MENU+POWER.
Stop and Verify: When the phone reboots, you should be greeted by a fresh install of Android. Go through the setup process again for signing into your Google account. You can double check that the downgrade was successful by checking your build number as explained earlier. Press “Menu”, then “Settings”, and click “About Phone”. Your version after the downgrade will read RC29.
Part 2. Install New Bootloader.
Now that we are running RC29, we can exploit the known security hole to gain permanent root access. The next step involves replacing the SPL or secondary program loader. This new bootloader is what allows us to load a custom build of Android. Note that the SPL is independent of the Android build that runs on top of it.
Since the downgrade wiped our phones, we will need to reinstall the root application we used earlier to finish up the process.
Download the root app again here: http://www.androidactivity.com/root/root.apk
Follow the previous instructions to install the root app and launch it. We will now perform “Step2: Download IMG and HardSPL files”. The security hole we will be exploiting requires you to type a command on the physical keyboard. After you click Step 2, wait for the download to complete and then perform the following steps.
- Go to the home screen and open up your keyboard.
- Hit enter, pause a second, then hit enter again.
- Type “telnetd” in all lower case minus the quotes. Ignore the contact search that comes up.
- Press enter again.
After typing the “telnetd” command return to the root.apk app and press “Step3: Protect your root”. This step runs a script that will perform the SPL upgrade. If you see any errors, it means the telnet session is not open. Return to the previous instructions and try launching telnet again. If you are still having problems with Step 3, reboot your phone and try again. After the script runs, we need to reboot the phone to apply the update file.
- Power off your phone.
- Hold down the Home key and power the phone back on.
- When you see the triangle with the ! inside it, then press Alt+L to display the bootloader options.
- Press Alt+S to apply the update.zip file.
- When the update is finished, you can reboot by pressing TALK+MENU+POWER.
Part 3. Upgrade the Radio Image to support Android 1.5
Before we move onto the last part, we must upgrade the Radio Image to the latest version that supports Android 1.5. The new radio image has been posted on HTC’s support website for download. In order to apply the Radio update, we must download the file “ota-radio-2_22_19_26I.zip”.
Update: If the HTC download does not work, here is an alternate link to download ota-radio-2_22_19_26l.zip.
Once the file is downloaded, it must be renamed update.zip and placed in the root directory of your SD card. This means to place it in the main directory and not inside any folder. If there is an update.zip file already present from the previous steps, it is ok to overwrite the file or delete it. When the radio image file is renamed as update.zip and placed on your SD card perform the following steps:
- Power off your phone.
- Hold down the Home key and power the phone back on.
- When you see the triangle with the ! inside it, then press Alt+L to display the bootloader options.
- Press Alt+S to apply the update.zip file.
- When prompted, hit Home+Back to write the image file.
- When the update is finished, you can reboot by pressing TALK+MENU+POWER.
Stop and Verify: You can check the version of your radio image to make sure it updated. Go to Settings > About Phone > Baseband version. The version number should end in 2.22.19.26l just like the original name of the update file.
Part 4. Install Custom Android Build.
Now that the hard parts are over, we are ready to install a custom build of Android. There are many to choose from, but I suggest the most recent build from JesusFreke. His version includes multi-touch support in the browser and a host of other features. I have chosen the JF build because it was voted the most popular and has been downloaded the most times. There are also custom builds available from Haykuro and The Dude that we will explore in a future post. For this last part, we will no longer use the root.apk application. It links to an old version of a JesusFreke build that we do not want to install. Instead, we will download the latest build from his blog http://jf.andblogs.net.
The file we want to download is JFv1.50 ADP1.5.
Please note that this cupcake build along with the others is based on the ADP version of Android and is different from the RC builds that T-Mobile offers. The Android Developers Phone version is the build given to developers and lacks the T-Mobile branded apps. The Release Candidate builds are approved and released by T-Mobile. You can swap back and forth between build types, but you will need to wipe your phone each time.
Once you have downloaded the update file JFv1.50 ADP1.5 it must be renamed update.zip and placed on your SD card like before. Make sure the file is named update.zip and copied to the main directory of your SD card. The most common problems I have seen are Windows users who name the file update.zip.zip by mistake and others who place the update.zip in the wrong place. After the file is in place we need to reboot and apply it:
- Power off your phone.
- Hold down the Home key and power the phone back on.
- Wait for the bootloader to display, then press Alt+L to display the bootloader options.
- Press Alt+W to wipe the data and cache folders. You must wipe when going form a RC to ADP build.
- Press Alt+S to apply the update.zip file.
- When the update is finished, you can reboot by pressing TALK+MENU+POWER.
After the phone loads back to the home screen, you are now complete. One of the first apps you should download is JF Updater. This will make getting updates in the future much easier and you will not have to repete all these steps.
Stop and Verify: Look at the list of programs you have installed. You should now see Terminal Emulator. This means you are now running a custom build. Launch Terminal Emulator and type the following command to display what version you have: “getprop ro.modversion”. It should read JFv1.50.
More To Follow:
- Creating an ext2 Linux partition on your SD card
- Moving your apps and cache to your SD card
- Installing and using a WiFi Tether app
I could keep typing forever, but I will stop and let people check for errors. Will update in the morning.

kudos.
Amazing guide, thank you sooo much.
Wow this tutorial s great. I was able to root without any problems. I found this AppsToSD 2 tutorial as well. I followed the directions at the bottom of the post just before the downloads. To download the files you have to register.

Hi,
Thanks a lot, I am a newbee and this is VERY helpful.
One question though: How can I return to the original T-mobile build?
Thanks
The process involves downgrading back to RC29 and then waiting to receive the official update. We will post a full guide later or I will link to one soon.
Question: What is the “Radio” Update specifically for…?
I have seen no official release notes, but some people reported increased battery performance. No idea to be honest. I see people say better battery performance with each update that comes out.
I can’t download “ota-radio-2_22_19_26I.zip” from the HTC.
HTC looks like they are making changes to their site. I added the alternate download link.
just in case there are some real newbies out there might be a good idea to state that Formatting the SD card will wipe everything off of it.
Only problem I had was that I couldn’t download the radio image from the link provided (HTC site). I was able to get it from http://android-roms.googlecode.com/files/ota-radio-2_22_19_26I.zip and transfer to sdcard from pc.
I totally screwed up my phone following other sites directions.
TY for doing a great job on this write up. However I did find that I needed to name my update.zip just update.
That is probably because, on your computer your file extensions aren’t shown so when you named it update.zip it came up as “update.zip.zip”.
Thank you, Thank you, Thank you!!!
I happen to be one of those newbies that wanted to root my g1, but never felt comfortable doing so because of the lack of knowledge. Thank you for simplifying the process. I still plan on waiting for your pros / cons of rooting.
Thanks again
Thanks alot!!
What’s the difference between going for a custom build, and using the build that’s on the HTC website?
You might also want to mention that the stock micro-SD card comes as FAT16(just in case anyone takes the statement that most come with FAT32 to mean that they don’t have to worry about it). I’m pretty savvy at this stuff(I wrote the apps to sd and open overclocker apps and wrote a tutorial on moving apps to sd manually) but still spent about 30 minutes trying to figure out what was going wrong because I assumed the stock one would be FAT32(who the hell uses 16 bit anything anymore!?!?!?!)
Also thought I’d mention that for the whole partitioning to make an ext2 partition(as noted in your future tutorials bit), I’m currently working with some of the devs(JF, MartinFick to name a couple) on making that MUCH easier.
Mark, that is great news. I had spoken with Martin and had been suggesting a UI for his scrips. It would be great to see this coded into the OS.
I was thinking something similar to the Disk Management app for Windows.
this is the best instructions ever will donate
Thanks!
One note:
If you get stuck on a flashing “Android”, then reset (talk+menu+power), load recovery mode (hold home while pressing power), then press alt+l to display commands, then press alt+w to wipe data, then press alt+s to reflash jf cupcake. I had this problem but this fixed it.
Thanks again!
Thanks, I knew I was leaving out an important step. If you don’t wipe going from RC to ADP, then you will surely get stuck.
Had the same issue but solved it as described
Kevin! You saved me! I was getting the endless Android boot screen. I re flashed like 3 times before I saw your instructions on wiping and re flashing. That sounded kinda bad.
Thanks again.
man u saved eerbody good looking out
Thank you for this information…. I was going crazy trying to figure out what to do about being stuck….
quick question if im in canada would it be wise for me to use this guide to root and update my phone? thx
The JF ADP1.5 build is an English build so you should be ok. I’ll see if I can find a concrete answer.
I just tried the US and UK dreamimg on my Canadian HTC Dream and it told me it was the incorrect model ID.
WOW!!!! Great Job. Reading the hundreds of pages on the forums left me more confused than when I started.
This is great. Thanks!
Well there was a problem when I did it for 2 of my g1’s. I could not go directly from rc29 to cupcake I had to go from rc29 then update to jf’s v1.41 and then to 1.5. Has anybody else experienced this issue?
I did my roommate’s phone last night and went from RC29 directly to JFv1.50.
What kind of problems did you run into? Did you perform a wipe before installing the JF build?
Ah, this reminded me, if people go directly from RC29 to Haykuro’s ROM it doesn’t have the recovery terminal(not sure about the dude’s) so I’d also suggest that people go through one of JF’s first.
Followed the steps religiously. Failed in step 1 – Get the following when it is rebooting:
DREAIMG.nbh – FAIL
BOOTLOADER -
RECOVERY –
BOOT -
SPLASH1 -
SYSTEM -
USERDATA -
RADIO_VZ2 -
Update Terminate
UPDATE FAIL
PLEASE HELP!
Make sure your sd card is FAT32. If it’s FAT16 it won’t work(the standard one is)
Mark, the problem wasn’t FAT, but the fact that my DREAIMG was corrupt (possibly because I didn’t wait long enuf for it to download completely
Thanks for your help!
If I cancel an update, I get into a multi-colored screen, that shows the following:
DREA100 PVT 32B RUUNBH
HBOOT-0.95.000
CPLD-4
RADIO-1.22.14.11
Sep 2 2008
Serial0
As Mark said, make sure your SD card is formatted to FAT32.
1. Format SD card to FAT32 file system.
2. Download the RC29 image again.
http://koushikdutta.blurryfox.com/G1/DREAIMG-RC29.zip
3. Copy the DREAMIMG.nbh to the formatted SD card.
4. Reboot phone holding down the camera button.
If you did everything correct, it should prompt you to press the power button to continue the upgrade.
Let us know your results.
The DreaIMG.nbh file that the root script automatically downloads is corrupted, even over wifi. I downloaded it to my PC directly and that did not work either. The link above no longer links to the file. Any updated locations for the nbh file?
This same thing is happening to my g1 as we speak please help email me if possible the link above doesnt works so what do i do!!! im freaking out stuck in marine corp training with my only connection to home
yea! man! was a bit confused at first, but I just downloaded both files using JF UPDATER , radio update and the jf cupcake 1.5, after downloading the radio update JF updater did the rest.
Thanks alot guys!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!:-)
For those in the uk, if you are already rooted just download “jf updater” from the market, once downloaded select it and click on, menu/ configuration/ system mod version/ all updates, JF will find all updates ie: radio update and cupcake update, install one at a time, after the radio file has been downloaded to your phone JF will ask “Verify and apply”, the same will happen when you download the cupcake update, just apply and JF will do the rest.
great stuff.
quick question – on your first step you state to have the phone connected to the PC, but there its not clear when/if you disconnect before you move on…
thanks again.
Thanks, I updated the text to clear that up.
Got it working! Thanks a lot!
My problem was that I had only part of DREAIMG on my sd card. So I put my SD card in my wife’s GPhone, copied the full version of the file and then followed the steps…..
Also, I did have to press Alt+1 to get the boot loader to come up with the ! screen
Thanks, I’ll add a note about downloading the dreaimg file again if the first attempt fails. I’m not sure how you were connected when downloading, but this is the reason to avoid Edge/3G when downloading the larger files.
I was connected with wifi (I think). Not sure if I didn’t wait long enough, or was distracted doing something else.
I would recommend people download the DREAIMG on their PC and then transfer the file – faster and safer (IMHO).
But my phone works beautifully now! Love the shell window and root access! Also the multi-touch is pretty cool to show off!
Why I would do al this if I gonna get the update anyway?
-You´ll get rid of some Tmobile features,but you´ll enjoy new ones.
-You´ll have root access.
-Better bluetooth.
-You´ll be able to install apps and caches on your microSD.
Those great reasons for me to upgrade.
Okay…
So, I got the same result as Ambarish.
…I made sure my SD card was formatted to FAT32, so for me that wasn’t it.
How do I get my phone to stop going to the bootloader?
…& how do I alternatively access my SD card ?
Are you talking about the red/blue/green screen? You press talk+menu+power to reboot the phone. You should be at RC29 when it comes back up.
I will clarify that step in the instructions. Thanks for the input.
Hi Linda,
As I said in my comment, your OS might be corrupted on the SD card. No problem. Just get a good clean version on the card and you will be in business!
There are devices that can let you access your SD card from a PC (using a USB port), if you can’t write to your card using your phone….
If you need help, you can email me at my first name at yahoo.com
In step 2, when I try to reboot the phone, while pressing the Home key, I do not get to the recovery console. Instead, if I hold the Home key, it keeps rebooting while displaying the G1 logo.
Hi everyone.
First of all I want to say thanks to Taylor for such an outstanding guide,it DOES work great,I started at 11:30pm Central Time and I am done right now.
I used the guide to upgrade two phones,mine and my wife´s and believe me guys it does work.English is not my first language so I had to read it slowly and a couple times.
Now I am thrilled with MY BRAND NEW G1.
Once again thank you and thanks for your time and effort.
Can Google (at the behest of T-Mobile) change future updates to the G1 to stop RC29 from being installable or usable in order to prevent this hack?
Or does T-Mobile not care about rooted G1s?
I think they already tried on the RC30 and other versions but there´s always a genius that fix the problem.
Ayo0o this is great, I did everythin worked out thanx meng =D….I had the other version 1.5 cupcake htc w.e and I didn’t like it the virtual keybord was wack and it had to manny problems and plus I didn’t have root acces and now I do with a 1.5 ver yayayayaya! I’m so happy and I jus download the app for tether and it works great everythin is cool man =)
im confuse i can get my phonr to show yhe base band we need ,,,,it shows 1.22.12.29 im i can pass step 3 plz help n i need 2.22.19.26l
To install the new radio update, you have to rename the file update.zip and flash it like the others.
had someone else root my G1, but after a while phone got slow, so i reformatted. now all apps and cache go to the device, how do i get them to go on my already partitioned SD card, any ideas?
If your SD card is already partitioned, you can try the Apps To SD program. You can download it from the Market for $1 or from XDA forums for free.
http://www.cyrket.com/package/com.appstosd
You other choice is to wait for the next JF release. Mike implies they are going to integrate this feature into the OS and make it “much easier” to manage.
Great guide guys. I just updated. Not nearly as hard as it sounds.
I protect my root and power off. When I turn it on holding the home key, the G1 logo flashes, then it flashes again but fades out. There is no text or anything else showing. What am I doing wrong?
Same problem here! No solution thus far.
Had to just start over. Didn’t have this issue this time.
The fix is as follows:
Repeat step 1, then step 2. I have no idea why, but that seemed to work.
Taylor, thank you SO much for posting this step-by-step tutorial. Not only that, thanks for your help via Twitter last night.
Like I told you, the part I missed was right after typing telnetd and hitting enter. I don’t think I could have done it without this page and your assistance.
As I told you, where I messed up was running the third part of the Root app under Step 2. I went right from telnetd to rebooting my phone.
The part about step 3 is all in one paragraph explaining what it does, which I think makes mind skim over it and look directly for the next list of steps — rebooting, etc.
I think this might clear that part up:
After we type the telnet command, press and hold Home key and re-open Root app.
Scroll down and pPress the button that says “Step 3: Protect your root”. This step runs a script that will perform the SPL upgrade.”
My hubby Howie was successful with his phone last night, and said he must have just done the right thing accidentally when he went through the steps. LOL When he tried to figure out why mine wasn’t working, he read the steps more carefully.
Thing is, he did the same thing as me and skipped re-opening the Root app. We both had done the telnetd, then immediately rebooted.
Thanks again so much for taking the time to create and maintain this tutorial — the long threads at the various Android forums just confused and intimidated newbie me. This I could handle (well, mostly! LOL).
You = rockstar.
Thanks for the feedback. That step is now updated.
Doing this the first time I somehow made it through and got this to work on my phone LOL. So you would think I would be able to do it a second time.
While reading your instructions the second time trying to do my wife’s phone there is one part that was a little unclear. This stumped me even after
I had successfully done it once. You state below that it’s time for step 3; you should change the directions a little in the first sentence. My wife
and I both were doing the telnetd command and then dropping down to the power off ect… So I think if you change that one line to “After we type
the telnet command, it is time for “Step3: Protect your root”. Go back and run the root.apk and select step 3″. Your instructions will be perfect
after you add that. Thanks for your help. It may partially be because I got up at 5:00am and it was after midnight when I was doing this. But a
little clarification would still be good.
After we type the telnet command, it is time for “Step3: Protect your root”. This step runs a script that will perform the SPL upgrade.
If you see any errors, it means the telnet session is not open. Return to the previous instructions and try launching telnet again.
If you are still having problems with Step 3, reboot your phone and try again. After the script runs, we need to reboot the phone to
apply the update file.
* Power off your phone.
* Hold down the Home key and power the phone back on.
* When you see the triangle with the ! inside it, then press Alt+L to display the bootloader options.
* Press Alt+S to apply the update.zip file.
* When the update is finished, you can reboot by pressing TALK+MENU+POWER
is this tutorial valid only for G1 or for HTC Magic too?
If applies to Magic , then how to go about the steps that involve hard keypad…. like Alt+s, Alt+l, Alt+w
anyone?
This app is only for the G1 aka Dream. I believe I have seen a Magic guide on the XDA forums.
is there a list of apps that aren’t on the ADP versions but are on the RC versions? running off of SD card would be nice, but i’d like to know what i’m missing first.
It’s pretty much MyFaves and the IM app. You still get Google Talk, but no default AIM, Yahoo, or MSN. You could use one of the alternate IM clients from the market that support all 3 and more.
its just the myfaves dialer yes? as in the silly lil spinny thing with pictures of the people to dial or message them?
Great guide, but I do have a question or two. I sucessfully rooted, and installed the jf1.5. My question is, how do I load a custom boot screen now. I simply cant get the phone to startup in fastboot mode. No matter what I try, it goes to the serial0 screen, then nothing. Also, the root application that is installed after the update just loads up as a blank black screen, I tried a wipe – as suggested on other forums, But still no luck in accessing the app. any help would be appreciated.
dont use mybackup, it can and will wipe your gmail contacts with no good way to fix it.
everything worked fine, i’ve been using JF’s image for months now, just needed to upgrade to 1.5.
one question tho, i used Droid tweak tools to set my autorotate but that doesn’t work with 1.5.. is there a way to set auto rotate wit 1.5? anyone??
Hi Taylor GREAT JOB !!!
Just wonder if you can write a guide on how to run apps from the sd card thx!!
Yes, I am waiting for the guys behind the sdsplit and apps2sd to release their next version of the script.

DHAN, there is a good explanation at this place:
http://android-dls.com/wiki/index.php?title=Haykuro_Apps_to_SD
(got the pointer from Jesus Freke’s blog)
Thanks so much for the tutorial! Got it working quickly and easily, for whatever reason I cant auto rotate on home screen, other than that everything is beautiful
From the home screen press menu.
Go to settings > sound & display > orientation.
You can also use the app Spare Parts to change the window animations and transitions.
Problems downgrading from kila RC33 to RC29. I did all the steps exactly as described, and when I reboot, I get the rainbow screen, it flashes “No Image file” real quick, then displays what “ambarish” was getting.
I’m using Ubuntu and formatted the SDCard using mkdosfs -F 32 and DREAIMG.nbh is the only file on the card.
I’m out of options. Any thoughts?
I talked with a guy today who did it with Ubuntu. Let me see if he can help.
@Taylor Wimberly: I spent over an hour scouring the UbuntuForums, and kept coming up empty. Not cause the answer wasn’t there, but because there are SO MANY answers. I eventually came across this one
Try the following code contained between >>>these<<>>sudo apt-get install gparted && sudo gparted<<<
gparted worked! Thanks for the tip guys! I would have thought mkdosfs would have done the same thing but apparently not.
I’m on my way to unrooted 1.5!! Thanks again!
Check that your DREAIMG file isn’t corrupt. I use openssl md5 to get an md5 checksum
when i try to update radio it tells me there is no such file i named it update.zip and put it on my card
it was the update.zip.zip rename the file update not update.zip
Your instructions were amazing and everything worked like a charm. Thank you SOOOO much for this tutorial.
i’ve tried updating my radio using update.zip and just update and it says it s bad.HELP??
Download the radio image once more and try flashing again.
can you post an md5sum for JFv1.50_ADP1.5.zip
when I tried to update it said my update.zip image is bad
I’m having problems with the last part of part 2, The script runs fine but I can’t get into recovery mode, it goes to the bootloader screen instead with the red green blue and white bands.
Hi! This guide is excellent.but I got a few questions.
I have followed the walkthrough to this point:
I have RC29 still, I have latest radio image and the recovery .img file applied. The root.apk can successfuly complete “Protect root” (tried again) but what worries me is that when I type “su” in terminal emulator, it says “permission denied”.
I can use telnetd and all the stuff, but should I have root on the phone on RC29 or not?? How can I check this?
Hi Leden,
I had the same question. If the root.apk program says it ran successfully, then it ran successfully. Try running it without executing the telnet command you will see how it behaves when it fails.
my phone is stuck at rc29..the radio image file is saying its bad when i try to update it. What should I do?
I used the tutorial and my phone works perfect. I am very computer illiterate and was able to figure it out. Thanks a million!
Just followed from start to finish and success with no problems !
Thanks
my phone is taking forever… loading the new blue/shimmering ANDROID screen. been 5 minutes… should I be worried?
nevermind, did a wipe and updated again and it worked! thanks for this guide!!
I had the same problem, and I fixed it the same way…except I had to reinstall the update twice.
GLAD I DID IT
problems, i had to install the files with a SD card reader. could not copy to sim directly from phone with wifi or usb. All the files that where copied with wifi and usb where not complet altho showed complete. not sure why. and yes i used the same usb port. worth the trouble figuring out…
I installed it just fine, the only problem was that it turned my laptop into a brick. =)
For some reason all the downloads that root.apk tried downloading were corrupt or incomplete. So my installs would fail. I ended up just downloading it to my PC and then transfering them to the SD card from my card reader. Everything else worked perfectly. Thanks for the great tutorial!!
a lot easier to fallow then other tutorials ive seen, good job
had to re-DL’d DREAIMG.apk from here.
http://files.lucidrem.us/_fd.php?file=jf/ROOT/DREAIMG-RC29.zip
I also had to use an SD card reader.
it was ‘buttah’ (butter) from then on.
excellent work you have done here.
hats off to ya. cheers.
completed successfully in 45 mins! great job!
Goodmorning folks i just installed the (JFUpdater) from the market,I did have root access on my G1 (JFv1.42RC33) yes im still rooted but to the new (JFv1.50) which came through an update upon installing the (JFUpdater ) from the market along with a few more updates like the (RadioImages)- (2.22.19.26I)-(JFv1.43RC33-Holiday) no i didnt wipe nor brush any dust from my G1 i simply installed and the phone did the rest..lol..i did loose (IM) but got back (google-talk) so im satisfied and if T-Mobile dont push or if im not able to recieve the New CupCake thats being released starting on May11th oh well im good with JF and i tip my cap to all the folks out there that recieves there Baked Cake..PS: thankz to JF for saving my G1……
Was very easy…now how do I tether it to a wifi connection? Or better yet, download directly to the sd card. Thanks for a very easy guide.
hi, what i try to update DREAIMG.nbh, it says update terminate update fail, what should i do???
please rely asap \
THANKS
mines says the same thing im kinda worried here!
hi, thx for the awesome tutorial!
Slightly off-topic: i used nandroid backup w/ the JFv1.3 build; but now i can’t seem to find nandroid for cupcake builds.. any idea as to where/how i can get & use it?? – as, obviously, being able to do a full backup before flashing/modding is extremely useful. Pl reply, TIA.
Something i find useful when booting off a newly flashed image and you can’t really see what’s going on-
-connect the USB cable
-run ddms on the PC
-as soon as it detects the phone (“online”) you should see the log messages in the pane below..
-alternatively, run
adb logcat
THANK YOU SOOO MUCH. THIS IS AWESOME AND I LOVE IT.
worked great thanks! the only problem was the step one DREAIMG.apk download..i had to manually download it from ERK’s comment and put it on my SD card…which is actually better because it’s much quicker that way.
There should be a warning that MyBackupPro will screw up your google contacts and wipe them out (from your google account, not your phone)
that’s great!! thanks!!
I guess i could’ve waited till T-Mobile’s version came out, but i needed an excuse to root my phone
You can quickly format your sd card to fat32 using an hp utility called HPUSBFW.exe. You can get it hereHP Drive Key Boot Utility or google it if the link dies. It’s nice for making a usb boot disk too.
I got up to “Part 3. Upgrade the Radio Image to support Android 1.5″ . But when I Downloaded the file, renamed it to update.zip and proceeded with following steps, it didn’t work. I clicked ALT +S to apply, but it went for like 1 second and then when back to the exclamation mark with the G1.
Can anyone help me out?
ADP1.5 have busybox and apps to sd built it, but can somebody tell me how I can set it up so the apps I install will be on my sd card. Thanks
ok i got up to the end of step 1, where it tells you to press the end button to upgrade, and it comes up with a message, “UPDATE TERMINATE”, “Update fail”, someone pleez help, i have a useless piece of plastic at this point
RE: Update fail.- Make sure you have removed the charger or data cable (my phone wouldn’t reset with it in) and soft reset CALL-MENU-POWER buttons.
Try update with DREAMIMG-RC7 this is for U.K
Worked for me.
@Androidandme
So I’ve rooted my phone. all works well.
QUESTION:
Does appd2sd copy all EXISTING installation files, etc. to sd?
or
Does apps2sd only copy new installation files, etc. to sd?
hi,
i’ve read the guide and i would like to ask: when i’m booting my phone with camera button pressed i’ve this screen
Screen on boot + Camera.
Is it normal ???? I’ve a build RC33 of firmware 1.1
On other guides i read that i should see three droids when i’m booting the phone with camera button.
I would like to make sure i didn’t miss something before starting this whole process
Sorry,
the photo of the screen is here
Screen on boot+camera
Holding down the camera button doesn’t power the phone on for me. The root.apk instructions say to use camera/power to turn on. That’s what works for me.
Thanks again… finally got some free time to do this today. Worked like a charm. Awesome tutorial.
Only problem I had was the dream file was corrupted during download (even on wifi). FYI the correct size for that file is 89,419 mb. Check the size of your download, if you have any issues.
Thanks!
After bootloader installation, the screen states to do Home + Back to reboot, not Talk + Menu + Power. The former worked for me, the latter didn’t. YMMV, but it’s a minor detail worth noting.
is the JFv1.50_adp compatable with uk G1 phones?
and if not where can i get it please?
Also to ken and brandon an anyone else havin probs loading dreaimg.nbh you might try the RC9 as you probably have uk phone. (i had problem loading RC33 which is u.s? ithink)
Scrap that last question -Yes the JFv1.50-adp does work with U.K! …..Sorted!
Must say toataly BIG respect to Jesus Freke and all the other codies out there that make all this possible.
sorry i meant DREAMIMG-RC7 thats what i used worked fine.
worked perfect in a flash
Hey. My phone still doesn’t have auto rotate. I’m also confused as to how to copy and paste in the browser. It just says “text copied to clip board”. Where exactly is the clip board. Thank you.
my phone is stuck in bootloader mode, the update failed and now i can’t get out of bootloader mode! someone help please!
I’m having the same problems. I’ve waited a long time and it’s STILL stuck on the red-green-blue bootloading screen. I think the problem why it failed to update was because the phone was already on rc29. anyone know how to fix this problem?
I had problems with this mod procedure. Couldn’t get into recovery mode and install Hard SPL. Followed the CoolPSTuts to get recovery installed and then came back to the rest of your install. Could be my mistake or problems with scripting program. Look forward to more tips for a beginner hacker like me! Apps to SD card will be a big improvement!
@Jay sometimes it takes a LONG time to get out of the bootloader when you’re upgrading your system. Just be patient, if it’s showing a graphic on the screen for what seems like a REALLY long time, just wait until it goes away. It should work.
i got update fail also, what can i do to bring my phone bak to life?
thank you SOOOO much. You rock, your instructions were so clear and perfect. Any noob will be able to root their phone if they just follow your directions. Thank you and thank you JF. Donations will totally be made to you both.
I cant seem to start recovery mode…im stuck on step 3…everytime i hold home and power it starts up normally but then instead of going to the triangle…it just reboots again…if
I keep holding on home it just keeps rebooting…sigh please help…thanks =]
cant seem to install from sdcard… i tried downloading through usb and through sd card reader but the system recovery utility fails to verify the update package it says E:No signature (369files)
E:Verification failed
Installation aborted.
any help? i know it worked b4 but since i wiped and started over it wont work anymore
belp! got it i think… needed to edit recovery.img 3/4 through copying wish me luck
So I noticed a few of the standard G1 apps missing like IM, and My Favs. There are a few others, but I’m not worried about those. Is there a replacement for these?
I got stuck at the Bootloader. it was updating and then at the end of the update it says update terminated update fail. what happened? i followed the instruction from the beginning. and now i cant exit the bootloader. pressing menu+talk+power only reboots and bring me to the same screen, bootloader. please help me. thanks
Try to flash it with the rc29 update alone so that you get your phone back to normal, then try to repeat the steps all over again, except skipping the part where you downgrade to rc29 (cause you would’ve done that already).
go to this site
http://forum.xda-developers.com/showthread.php?t=463779
and follow his steps. once you’ve done that, your phone should be downgraded to rc29 and then you can start steps 2 and up.
Credit to xda forum.
It worked as a charm!
I just followed each step and finally I am free from T-Mobile lazyness! Thanks a bunch
awesome, thanks!
Used WiFi to download the file directly to phone but it must still be damaged. It failed and now I’m stuck on the red/green/blue/white screen. Now what??
I finally got things running again by buying an SD card reader and getting the uncorrupted file on it, but now having the same issue as Max:
I cant seem to start recovery mode…im stuck on step 3…everytime i hold home and power it starts up normally but then instead of going to the triangle…it just reboots again…if
I keep holding on home it just keeps rebooting…sigh please help…thanks =]
Thoughts?

Hi there, can u pls tell me how can i go back to the factory programs. because i had problems doing this root’s process. i’m now in the first steep with the green, red, etc screen, and i did all many times, i formated the sd, I get the RC-29zip from my pc and copied to the sd, and I can’t go out of this. if somebody can help me PLS…

awesome tutorial!!
worked flawlessly.. Thank You!!
upgraded easily. but now my phone in general is a lot slower. some screens wont even pop up. scrolling is also very choppy. Help!
Did you wipe? With a fresh install it should be noticeably faster.
I did wipe as per part 4 in the 4rth bullet above
worked great for me! Thanks for posting a great how-to!
sorry to double post but if it helps, I rooted my phone months ago and installed the new bootloader last night. so I picked up on step 3. This where i got the root instructions from http://forum.xda-developers.com/showthread.php?t=442480 and here is the forum I used to get the new bootloader http://forum.xda-developers.com/showthread.php?t=462512 I rolled through the installation steps and got stuck @ step 6. so then I came here and finished up. any ideas why my phone is acting so slow and choppy?
everything was great if you cant do this you dont need or deserve a g1!!! lmao cupcake is off the FU*&Kin hook!
i look forward for more updates like running mostly everything off your sd card!
I used ERK’s link above and redid the entire thing and it worked for anyone having the same issues…
i tried this and the google apps keep crashing wont let me do anything.. , wiped installed again no luck.. it worked for 2 hours.. (it was missing im.apk and myfavs.apk).. ??
now i am tring dudes release instead of jesusfrekes
Followed this guide to a tee and worked perfect for me. Great job all.
works great. thanks for the easy tutorial
when i the bootloader comes up to update the status bar reaches 100% then its turns red adn says update terminated update fail. now my phone doesnt work at all… what do i do?
okay..this happened to me..i was being a nube !..lol
dont worry..just listen..u need to take out ur SD card.. and connect it to an adapter..then to ur computer.. then u open it up..and delete the file name dream…or w.e its called… then.. download the file to your pc.. and rename it “update” without the quotes.. dont put “update.zip” because its already a zip file -__- … then try to boot it again..and it should work =)
How do I do and ext2 partion on the sd card to be able to apps to sd?
Mine did the exact same thing. No matter how many times I take the battery out and restart the process, the radio v2 fails, and yeah, I can’t use my phone now either.
I have trouble downgrading my RC33 to RC29. It keep saying no image found.
I downloaded the DREAIMG.nbh using PC and transfer it to FAT32 formatted 2GB Kingstons micro sd. Some thread suggest remove nbh but that didn’t work either.
Any ideas?
Finally found the reason……somehow I need to use connect the phone to USB to format it to FAT32. Using card reader doesn’t format the SD card in the right format……….even though I do it in the same way……now I can FLASH it finally….:)
thanks so much for all these great works u did for us,
it’s the best guaid ever!!!!!!!!!!
I got everything to work except that jesusfreke’s website is down and I can’t download the cupcake file to update my phone
Got it working eventually I searched around and found someone else hosting the file and it works fine now lame that the site is down and download doesn’t work.
OK, I went through this but may have screwed up the SPL since all I got was the “Android” after the G1 and it kept showing the ANDROID Graphic over and over and over again… Maybe I screwed up the TELNETD part?
Wow, I guess I need the sub beginner guide
The fail is strong with this one…
Im getting stuck on updating my radio image i renamed it “update.zip and put it in my root folder for my sd card and when i get to the part where i have to update (alt s ) i get this msg ” E:Can’t open /sdcard/update.zip (Bad) ” and it aborts the installation…. Help what did i do???
it installs it and finds it just when it goes to open it errors out someone please help
Email : skepsis12@gmail.com
skepsis,
Just taking a guess here but…
Try downloading it again, then renaming it again.
Make sure you don’t have any other update.zip files left in there.
(I renamed each update.zip to update_old.zip and update_old2.zip, etc, etc) after I used them…
2nd time through everything worked fine for me.
I went with the default JF Android from the root.apk step 4 and then updated it with JF Updater to the newest one.
A word to the wise. If you are trying to recover a pseudo bircked phone you actually need to unzip the dreaimg file if you get if from somewhere else. Not just rename the zip.
It should be noted that you MUST be in a T-Mobile area to sync up initially. If you are roaming on AT&T, the initial sync will not work.
I appear to be incorrect. Apparently, having EDGE while roaming works, but GPRS while roaming will not.
Now that I’ve installed JF Cupcake, I no longer have the Amazon MP3 app on my phone. Was that a T-Mobile app? How do I get that back on? It doesn’t seem to be in the Market.
I have been searching everywhere for it as well. I really liked that app and now it is gone. Any solutions to this ?
I’m about to get a G1 tomorrow to use on AT&T.
I shouldn’t have a problem using this guide even if I’m not using t-mobile, right?
Colin Dean’s post just scared me about having to use t-mobile to sync it first…
I am using AT&T with my G1. This worked perfectly. Just Keep instructions close on how to set AT&T up as an access point.
Also, you do know that you won’t get 3G through AT&T, right? EDGE only.
ok i just got mine to work,,,, but after doing every thing word for word. and useing
-2 computers
-a jump drive
-and micro sd converter
-and 3 hours of my life.
-and back tracking 2 times.
but man it was so worth it.
i just hope that this update will really help the battery last 20% more. even though its just 20% anything will help
thank you
This block of instructions was and will be very difficult person if you don’t pay close attention to detail and follow the instructions as it says. I read all the reviews and people were complaining that it doesn’t work and blah blah blah..but trust me it does. It’s take a hell of alot of patience and focus because it’s alot going on. Thanks to whoever wrote this, you did your best..
The walk-through worked like a charm for me. Thank you!
However, I received several failures due to the nbh and update files being only partially downloaded. I *highly* recommend downloading the nbh and radio and update files via your PC and copying them to your sd card (after formatting of course). This will save you a bunch of time and prevent ‘update fail’ messages.
I run Linux and thought I would share my recommendation for formatting the sd card for anyone interested.
$ dmesg | tail -25
$ mount | grep /dev/sd{x}
$ sudo umount /media/
$ sudo mkfs.vfat -F 32 -I /dev/sd{x}
Where x is your sd card device from dmesg.
Where ‘device’ is an auto-mounted device.
Absolutely brilliant! Thanks so much for the clear walkthrough!
Instructions and installation went perfect very good step by step instructions. Thank you I have Cupcake 1.5 and took me 30min instead on waiting for T-Mobile.
Excellent guide – followed start to end… not one problem. Great work!
Yeah… downloading DREAMIMG.nbh from the G1 one failed horribly. Even after 3 times. I’m thinking something is amiss with the file on that site? I wouldn’t even try. Just download from your computer and manually move to the SD.
G1 Rooted not bricked!
Moved /data/app and /data/delvik-cache to SD Card.
So far so good!
I hope T-Mobile doesn’t figure out a way to brick me.

What if you have rc#28 do you skip 1st part ?
Awesome tutorial for newcomers to root, looking forward tot he SD apps and cache tutorial
Awesome, worked flawlessly, looking forward to the Apps to SD tutorial, I”m trying to figure it out as we speak, but theres no clear place that gives me a step by step on how to do it.
OK, guys, I rooted my G1 with cupcake today and feel happy eith this. As I don’t even have T-Mobile operator in my country (I bought my phone on ebay) that descision was not hard for me
Now I can stay with latest Android updates with no dependance of T-Mobile restraints!
BTW, does anyone know how to get rid of boot logo of T-Mobile. I really don’t like their logo.
awesome walkthrough.
FYI if anyone had the same problem as me.
Bought the phone from an australian store, it got sent from HK so it was the T-Mobile US edition. Not happy
I had an issue of the phone continually sending an SMS to the international number 453 and costing me 35c per damn sms. So I followed this guide and got it to version 1.5.. Hopefully without the tmobile MyFavs application which was apparently sending the sms!
Now to wait 24 hours and see if it worked and I have any credit left
hello
i have not yet rooted my phone, but i am thinking about doing so, but i recently updated to the UK’s version of cupcake, and i wanna know it the down grader will work for it. i really want root access, but i also dont want to take a chance of frying my phone. any help will be nice. thanks
i seem to keep getting stuck at the radio image download into the phone and its killing any suggestions?
Great tutorial…
My advice to all: read through it twice to only have to flash the phone once.

Hey, I am having troubles with the JFv1.50_ADP1.1, specifically. I can and have updated my android, rooted it, and worked to update it to 4.1_RC33 (or 4.3_RC33). I want to bridge that gap and go into the android developer’s platform (ADP).
Whenever I install the JFv1.50_ADP1.1, the phone bricks on me. The phone will display the white / silver boot screen with “TMobile G1,” and will stay there however long I desire. I cannot get past that stage and reach even the glowing android (or whatever boot screen comes next on this update). So, any tips on how I can get into the JFv1.50_ADP1.1? Right now I am running JFv1.41_RC33.
I am trying to update with the JF updater app, but it all is looking the same!
Somebody please come to my aid man, im freaking out! (email me at JwRudnik[attt]gmail[dottt]com) and fast lol
Wow, just as i click submit, the screen changes.
Ahh, I can sleep well.
I am on the blue screen with a flashing android.
Still email me, I want to hear from you!
Oh, PROTIP: if all else fails, update simply to JFv4.1 and download the JF Updater.
somebody can helpme? I try and try and try

THANK-YOU
very good walk through…although this is easily the most simple flash opperation I’ve had to run…exploiting the PSP is much harder.
One thing to remember if you’re getting a stuck blue android logo you need to use Alt + W before applying the JFmodded cupcake build…otherwise you’ll be stuck in a small loop where the build keeps restarting because you haven’t wiped the cache and data areas allowing JF1.5 to create new ones….if you have this loop the image will stick during animation and the screen will flash black for a split second and then the build will restart….loop, rinse and repeat.
You can start step 3 over again if you run into this error.
Haha. I downgraded/ cfw’d my psp also, but I never bricked it (maybe a semi-brick when flashing themes, but never a real brick).
You are right that this is much easier though.
Wow… For me at least, this guide did not work at all.
I’m not saying that its bad, the problem for me was that the root app which is used for each step didn’t download files correctly for me.
I got my g1 rooted and updated to 1.5, but I had to download the downgrade and spl from other links.
My phone did get bricked when trying to downgrade, so I do not suggest using the root.apk application here. The update files all ended up being corrupted. I just did it entirely through the computer, it is just as simple.
If you get any of the update terminate errors or something, look for the guide on xda-developers.
I just wanted to thank Taylor, and everyone else who worked on the bits and pieces that make this work, especially JesusFreke. Thank you ALL.

I’m having the same problem as torres. I have reformatted my card and started from the end of step 1 twice. Now I get stuck at the end of step 2, because the phone will not co operate using the update at the end of it.
I’m VERY tedious when it comes to these kind of things, and I am rather frustrated. I’ll be looking for help on different boards, but if anyone has any ideas, email me or hit me up on twitter @dannybwheeler
Great write up. Might be handy to put here for Optus Users in australia the APN details.
APN Name: Optus Internet
apn: internet
Worked like a charm. I like the suggestions for JF OSes, that helped a lot.
Good job.
For those that are having problems, I suggest you verify the spelling of all files. Worked for me coming from RC33 to RC29 to rooted to JesusFreke’s 1.5, T-Mobile US.
My Update failed during DREAIMG.nbh and I cannot revert.
Can someone post the URLS that are listed when you run ROOT.apk so I can download the files I need to my desktop and then move them to the SDcard?
The specific one I need is the URL for DREAIMG.nbh
Thanks,
It worked fine for me but…..eversince i rooted my phone it force closes alot and sluggish…does anyone know why??
I’m getting the Update Terminated UPDATE FAIL in step 1. Is there any way to get the phone back to normal?
Nevermind, figured it out. The dreaimg.nbh that root.apk downloaded was incomplete.
I just did the update. Took about an hour and everything worked perfectly. Thanks so much!
ONE THING TO CLEAR UP though!
The part where you reboot, then press enter, then enter again, then type telnetd and enter again – I expected a terminal window to open up or something.
An easier way to explain how to do it would be like this:
Click on “contacts” and then type in “telnetd” and ignore the contact searching. After you press enter, you won’t see anything happen, but don’t worry, it will happen. Then go back to root.alx and proceed to step 3.
I only say this because I was stuck on this step thinking I broke it for about 10 minutes.
All works well except when i go to restart in recovery mode after “protecting root” it just brings me to the bootloader and then will do nothing untill i reset.
Suggestions? please and thank you….
I did everything BUT…my phone is stuck on the android logo…what do i do?? I tried rebooting it a few times…still gets stuck on the logo
OK, I successfully installed the root app and everything went fine. I booted the phone and everytime I try to login to my Gmail account, it says it can’t login.
I’m using a Dev 1 phone on AT&T.
Anyone else having this problem?
Just an FYI to anyone doing this who is on AT&T’s network, I was unable to login to my Gmail account after step one. I borrowed a friend’s T-Mobile SIM and it logged in perfectly.
Just a word of warning.
Last update on this: Turns out if you add and AT&T APN to your phone, it should work (Menu –> Add APN). You can try these settings:
apn:wap.cingular

I am really stressed. I have been successful with all the steps, but when it comes to adding the renamed folder for radio as update.zip on my phone and try to install it, its unsuccessful. PLS HELP.
Note about root access on JF1.50.
I’ve had this for a little over a week now. So far, great.
Today I tried to get root access in a terminal and it failed. Tried everything I could think of short of a reload of image.
At wits end when I finally noticed that I had turned off USB debugging. (I didn’t like the effect when it was plugged into a computer.)
If you turn USB debugging off, (Settings->Applications->Development), the SuperUser application no longer functions so you cannot get root access though a terminal (and I assume not use anything else that requires SuperUser to run).
Can anyone else confirm this or am I just an idiot? (If I were placing bets, I would bet myself an idiot.)
No you’re spot on about the USB debugging and SU… I remember reading that somewhere on xda-devs.
Is there anyway to install only certain apps? like the video recorder?
When I tried to update to 1.51 i ran in to some problems and ended up having the do the DREAIMG.nbh in order to get out of the boot loop. I’m wondering if I still have root or if need to redo that? I can’t find the answer answer anywhere, any help is appreciated. Thanks
Totally off topic here, but does anyone else think the cupcake upgrade lowered the software amp level of the external (speaker phone) speaker? Before I upgraded I could hear anything loudly and clearly from the speaker, now…. not so much.
Suffering an epic fail on step one. I have the DREAIMG.nbh file on my SD but the bootloader says nothing more than-
*loading
*checking
*not allow
The SD was formatted beforehand and I followed the instructions carefully.
I’m running on RB43 currently, despite trying to perform the full reset.
Any advice would be MOST appreciated.
OMG! I have been doing this for hours…
SAVE ME! I am getting stuck on updating my phone after the TELNETD step, I cant get the recovery screen to pop up, all i can get is the rainbow screen and pushing ALT+L or S doesnt work…..
HELP!
Beautiful tutorial.
Came across a couple of dead ends but I managed to dig my way out of them.
Now… can someone please direct me towards of lists of themes I can use for JFv1.5 ADP 1.5?
Can I use an ADP1.51 theme on the 1.5 built?
If I root my phone and install Cupcake, will that allow me to use it without data plan? Phone worked fine for a few days now I am unable use wifi to get email and use apps that use it either?
I am a linux guy and would have no problem doing the install, just want to make sure first.
email me if anyone can help

Thank you
I rooted my phone thanks to your kick ass guide. I was just curious if i wanted to switch back to RC version, how would i switch back to RC33. Or is it possible. thanks and keep up the good work. Bump
I am in South Africa on the MTN network. Will this work for me?
I tried checking my build version and there does not seem to be an “RC” number. Under “Build number” is the following:
1.58.421.1 PLAT-1.0_gms-144337 CL#20538 release keys
Thanks for any advice!
Hey Martin, ek sit met dieselfde probleem, het jy al reg gekom?
Hey,
I was wondering, the 4th and last possible file you can download from the root.apk file, JFv1.42_RC33, what does it do? and how do i install it? i have it downloaded…do i have to rename it “update” and do the installing process of it?
Thank You!!
your guide rocks!!!
