How to manually install the official T-Mobile Android 1.6 on your G1

T-Mobile has started sending out Android 1.6 to its customers in an over the air update. The rollout is staggered and occurring over several weeks. You can stare at your phone endlessly waiting for the download or you can manually download it yourself.

We have discovered the file for the T-Mobile G1 which updates your phone to Android 1.6. This file is being hosted by Google so I don’t think anyone will complain about distributing it.

For the full list of Android 1.6 highlights, visit the official Google Android site.

If you have a T-Mobile myTouch 3G, please be patient while we wait for the download link to be discovered.

Method A – My G1 has the official T-Mobile version of Android 1.5

Read first: This method is for people running an official T-Mobile USA version of Android. You will be downloading the official update file from Google and manually installing it on your phone. The update file is the exact file that is being sent to phones over the air, but this method allows you to manually download it (instead of sitting there waiting).

Warning: Some developers have not updated their apps to be compatible with Android 1.6 yet. Check your favorite apps to make sure they have been updated and contact the developer if they have not.

Warning 2: If you have a home replacement app that does not support Android 1.6 you may get stuck in a force close loop. You can boot into safe mode and uninstall the offending app. Hold down Power+Menu when turning on the phone and keep holding down both buttons until the phone boots in safe mode. You can then go to Settings > Manage applications to uninstall the app.

  1. Download T-Mobile Android 1.6 (DRC83) from Google. (Search Google for “signed-kila-DRC83-from-CRC1.c41b93c1.zip” if the link is removed)
  2. Copy the downloaded file to your phone’s SD card. (Advanced users only: Use the command “adb push signed-kila-DRC83-from-CRC1.c41b93c1.zip /sdcard/update.zip”)
  3. Rename the downloaded file to update.zip (Make sure you can see the file extension. Many users make the mistake of naming the file update.zip.zip)
  4. Reboot your phone into recovery mode. Power off the phone first and then hold down the Home key while powering it back on.
  5. The recovery mode is finished loading when you see the ! mark inside the triangle. Press Alt+L  to display the list of options.
  6. Press Alt+S to flash the file update.zip.
  7. Wait for the update to apply. Your phone may reboot during this process so be patient.
  8. Press Home+Back if prompted to reboot your phone.

Verify: When the update is complete you can double-check your version of Android by going to Settings > About phone.

The build number should read DRC83.

The build number should read DRC83.

Method B – My G1 has a hacked version of Android currently installed

Read first: This method is for people running any hacked version of Android. Installing the official T-Mobile version of Android 1.6 will wipe your phone and you will lose root access. This is for people who wish to return to the latest default install of Android.

Warning: Some developers have not updated their apps to be compatible with Android 1.6 yet. Check your favorite apps to make sure they have been updated and contact the developer if they have not.

Step 1: Downgrade to RC29

  • Download the file DREAIMG-RC29.zip (Search Google if this link is removed)
  • Unzip the file DREAIMG.nbh and copy it to your SD card home directory.
  • Power off your phone first and then hold down the camera button while powering it back on.
  • When prompted, press the power button to begin the downgrade. Wait for it to finish and display the rainbow screen. Press Talk+Menu+Power to reboot your phone (or just pop your battery out once the downgrade has finished)

Step 2: Upgrade to Android 1.5 CRB43

  • Download the file signed-kila-ota-148830.de6a94ca.zip (Search Google if this link is removed)
  • Rename the file to update.zip and copy it to your SD card (Advanced users only: Use the command “adb push signed-kila-ota-148830.de6a94ca.zip /sdcard/update.zip”)
  • Reboot your phone into recovery mode. Power off the phone first and then hold down the Home key while powering it back on.
  • The recovery mode is finished loading when you see the ! mark inside the triangle. Press Alt+L  to display the list of options.
  • Press Alt+S to flash the file update.zip.
  • Wait for the update to apply. Your phone may reboot during this process so be patient.
  • Press Home+Back if prompted to reboot your phone.

Step 3: Upgrade to Android 1.5 CRC1

Step 4: Upgrade to Android 1.6 DRC83

Verify: When the update is complete you can double-check your version of Android by going to Settings > About phone.

The build number should read DRC83.

The build number should read DRC83.

    hey i have a rooted g1 and have been trying to unroot for awhile now but cant find out how. can u please help me so i can get the donut update for my g1? thx,dan

    • http://androidandme.com Taylor Wimberly

      Finishing up the guide to unroot and install Android 1.6 now. You need to downgrade to RC29, then install CRC1, CRB43, and finally DRC83. I’ll have the steps up in awhile.

      • http://none Maximus

        Does the 1.6 update require a radio version update as well or does it accomplish this automatically? Does a recovery.img need to be loaded as well?

  • dan horner

    thx, cant wait for steps =)

  • Robert Barrett

    Cyanogens already has all the new features. Its a shame some people think going unroot will make their phone better with this new download. And it wont. I am keeping my Cyanogen 4.1.11.1 as it works like a top and has extra features that Google will never have on this as they refuse to learn from the pros. I think it all comes down to money and time as they have a schedule to follow with new Android phones with the 2.0 and up in the future.

    • Tallbruva

      You are SO right! I just went to his site and checked out the screenshots of his mod as well as the themes. There’s nothing, and I mean NOTHING on the cell phone market that compares. And yes, that includes iPhone. I don’t know why I took so long to see the light.

  • soultruth

    am i the only one gettin an “error at line 2″ scipt??? whats goin on??? im not new to doing this. i have a g1 as well

    • http://androidandme.com Taylor Wimberly

      At what step did you see this error message? I have never heard of this message before.

      • flurin

        i get the same error. im pretty sure that’s because my phone is on cupcake CRC37 and not CRC1. @soultruth what cupcake build do you have?

        • http://androidandme.com Taylor Wimberly

          CRC37 is a UK version. This update is for US G1 phones.

  • Freddy

    OMG thank you guys sooo much! just did the update and it works PERFECTLY on my phone :)
    woot woot ^.^
    thank youuuuuuuuuuuuuu :)

  • mike

    will this work for my mytouch?

    • http://blog.tenkely.net Tenkely

      Nope.

      • Luis

        I have a mytouch 3G. Once, I rooted my phone with cyanogen and used flash cyanogen recovery 1.4. I switched backed up the phone to its original state ( i dont know if this un-roots the phone). I received to OTA of 1.6, downloaded it, but when tried to install the phone restarted and cyanogen recovery booted up, not allowing me to continue and aborted the installation. When i turned on the phone, the update was not available in the “system updates” section, where I initially checked where the update was. Now I am not able to do any update. What is the procedure in this case, if any? What should I do now, besides of waiting for them to send the OTA update again, if they do…

  • bob0mb

    so i am stuck in an endless loop of “force close” cuz i didn’t switch out of Open Home before i updated . any way to get around this?

    • http://androidandme.com Taylor Wimberly

      You can boot into safe mode and uninstall Open Home. Hold down Power+Menu when turning on the phone and keep holding down both buttons untill the phone boots in safe mode. You can then go to Settings > Manage applications to uninstall the app.

      • bob0mb

        would clearing the default boot into Open Home work as wel, or should i just dump it completely?

        • http://androidandme.com Taylor Wimberly

          It might work. I would just uninstall the app till it gets updated.

          • bob0mb

            i think it has been updated, but i’ll dump it for now . thanks for the quick response

  • Richard

    I did everything the way it said but it says no such file!!

    • http://androidandme.com Taylor Wimberly

      If you get the error message “no such file” this means there is no file named update.zip located in the home directory of your SD card. Make sure the file is named update.zip and not update.zip.zip. Also make sure the file is located in the main directory of your SD card and not inside any folder.

  • Richard

    I did. I renamed it update.zip and just dragged it onto the sd card.

    • http://androidandme.com Taylor Wimberly

      If all else fails and it will still not recognize the file update.zip try the following.

      Format your SD card using your phone or pc. If using your PC, make sure it is formatted to FAT32 file system.

      Warning – Formatting your SD card will erase all info so back it up.

    • sao paulo

      just rename the files by typing update

  • ravila88x

    Do you have to uncompress it?

    • http://androidandme.com Taylor Wimberly

      No, just rename the DRC83 file to update.zip

      If you try to uncompress the file it will not work.

  • matt

    the steps worked perfect for me, on my non-rooted official t-mobile G1. thank you!

  • ravila88x

    Ok so heres the deal. I got a G! not rooted all factory from Tmobile. I did everything right downloaded the file renamed it to update.zip dragged it from my laptop to the sd card. then did the boot process. and it says error?? HELP PLZZ!!!

    • http://androidandme.com Taylor Wimberly

      What is the exact error message? If it says update failed after finding the file, it might be corrupted. Try to download the file from your PC and not over 3G or edge.

      • Richard

        it says cant open/sdcard/update.zip(no such file or directory) installation aboreted.
        But i downladed it from the link up above 3 times already from my pc. And the file IS there. i dunno im loost!

        • http://androidandme.com Taylor Wimberly

          Sounds like you are using Windows and have file extensions hidden. View the file properties to make sure it is not called update.zip.zip

          • Richard

            hahaah. Yup that was it right there. i looked in properties. yup it was update.zip.zip so i just named it update. and it works. its installing now. thanks for all the help.

  • Matt

    Can’t wait for the myTouch update.zip! Thanks for keeping us posted!

  • Mark

    What should one do if the DREAIMG.nbh file is not recognized in bootloader mode.

    • http://androidandme.com Taylor Wimberly

      Did you extract the nbh file from the zip file? Try to redownload it and make sure it is in the home directory of your SD card. Once that is done, hold down the camera button and power on your phone.

      • Mark

        I am continually told there is “No Image File!” even though the DREAimg.nbh file is on the root of my sd

        • Mark

          For anyone who is having the same problem I am, reformat your SD card to FAT32 from FAT. This was mentioned above, as well.

        • dan horner

          yeah same thing happened to me! how can we fix this! i hav tried to redownload like 7 times and it still wont work. plz help?

          • Mark

            You have to reformat your sd card. First back up everything you have on the sd card. Then, when you are on a pc, go to my computer and find your sd card. Right Click the sd card icon and go to the reformat option. You should be able to go from FAT to FAT32 here. Keep in mind that reformatting will delete everything on the sd card. This is why i recommend the back up.

          • dan horner

            thx for the help. it works now! =)

  • Matt D

    i need help. i boot into recovery mode (home+power) and it gives me the triangle with exclamation point or whatever, then i press menu+l and nothing. press menu+s, nothing. my keyboard does not work. i can press home+back and reboot the phone, though. anybody know what i should do?

    • http://androidandme.com Taylor Wimberly

      I can’t help you if you don’t read the instructions. You are supposed to hit Alt+L. Not Menu+L.

    • http://www.nexsoftware.net nEx.Software

      Press Alt instead of Menu. :)

    How come the youtube app is not present anymore

    I keep trying to download crc1 file through my g1, but it keeps telling me “download unsuccesful. File not supported on phone.” So I’m stuck on crb43, don’t know what to do now?

    • http://www.nexsoftware.net nEx.Software

      Install Download Crutch from the Market (or any of a number of File Managers) or download on your PC then transfer to your SD Card over USB.

  • SquirrelWithAGunAtTheZoo

    Does anybody have any clue whether these steps and the 1.6 image shown will work for Tmobile G1′s from countries like Germany, the Netherlands?

    • Jonas

      just tried the update over here in germany.
      not successful.

      • SquirrelWithAGunAtTheZoo

        Could you at least roll back to Cupcake?

      • Nigel

        Yes, mine is Build CRC37

    Now it’s installing.

  • Brian S.

    I got the donut push on Friday. Since then, I cannot access the browser and many other basic functions of the non-rooted G1. The browser gives me the error “The application Browser (process.com.android.browser) has stopped unexpectedly. Please try again. So I downloaded the file above and tried to reinstall. When I hit alt-l, alt-s – I get “Install from Sdcard, Finding update package, opening update package, verifying update package, installing update, installation aborted. Any idea of what is happening or what I should try?

    I NEED HELP!!!!!! everytime i copy the dreaimg.zip file to my sdcard and turn off the phone then power it back on while holding down the camera button the rainbow screen says loading….no image found. plz help me!!!!!! thx,dan

    • http://www.nexsoftware.net nEx.Software

      You need to extract the DREAIMG.nbh from DREAIMG.zip and put the nbh file on the SD card.

      • dan horner

        sorry yeah i meant dreaimg.nbh i was in a hurry when i waS typing

    • Slater

      Dan, I had the same issue. All you have to do is format(fat 32) your sd card and try again. It will work.

  • youngn

    It worked fine for me baaaaaaaaaaaaby!!!!

  • jdarlove

    Something that isn’t really clear in th instructions is that u MUST uninstall Open Home or Ahome before u install the 1.6 update. If you don’t it won’t work.

  • CTown

    Or, if yo have a rooted G1, just go here:
    http://forum.xda-developers.com/showthread.php?s=57bf25f185ee958eced87d7594a54171&t=566130
    and download the newest rom and flash
    It is the official APD1 rom, but modified so it will still be rooted, at the expense that PDF viewer will not work (v3.0) or might be excluded in future builds.

    someone please help -

    • David

      If you have Vista, rename it to update. If you name it update.zip you may not notice that the file name renames update.zip.zip. Put it on the root of your SD card and do the rest that you may know.

    • http://Website Eduardo C

      Dude, Don’t name it “update.zip,” I found that by renaming it to “update,” without the .zip part, and reboot into safe mode, the phone will automatically add the “.zip”. So basically, dowload the update, rename it “update” and flash it. Oh yeah, and follow the rest of the instructions as it says here and you shouldn’t have a problem. Hope this helps papa

    I’m having some issues here.. I had 1.6 cyanogen on my phone and was having a lot of problems, so I wanted to go back to stock 1.6.

    I can complete step 1 without any issues, but when it comes to step 2 I get the following error:

    E:Failure at line 2: assert file_contains(“SYSTEM:build.prop”, “ro.build.fingerprint=tmobile/kila/dream/trout:1.5/CRC1/150275:user/ota-rel-keys.release-keys”) == “true” || file_contains(“SYSTEM:build.prop” “ro.build.fingerprint=tmobile/kila/dream/trout:1Installation aborted.

    Any help would be really appreciated.

      For anyone else who gets this error:

      I left my phone on, went to sleep, and woke up to an OTA update. It successfully installed 1.6 and I was good to go. Just take a little time I guess.

  • http://Website Alain

    Salut ! voilà j’ai un problème avec la méthode A, je fais tout ce qu’il faut, je change le nom en update etc. etc., mais c’est au moment de lancer la mise à jour sur l’android que ça m’affiche : installation avortée.
    Pourquoi est ce que ça m’affiche toujours ça alors que je fais les bonnes manipulations ?

    Thank you. I was running Cyanogenmod 2.1 on HTC Dream, and it bricked. This was the only way I could save it, until I can update to CM 2.1 again.

Before RC29 i had JF1.51 and it gave me the same problem. I have tried it with the original SPL and HardSPL, they all give me the same problem. Please Help

  • Wesley Lutter

    My HTC G1 is a phone that i purchased when I was stationed in Italy. It is still running the 1.1 firmware version and i am unable to get it updated now that I am back in the states. I was wondering if you knew some way to update it or make it possible so I can update the phone. I tried to update to the 1.6 version and got a message that it was not supported by the phone.

    • Josie

      Hi there, I downgraded to the 1.0 firmware! I followed from the 2nd step onwards and it worked perfectly! :)

  • Thankful

    Thank you so much! I downgraded my dream to the Android 1.0 firmware in order to root it in order to install the Gingerbread update… Little did I know all the files I would attempt to use after the downgrade would be corrupt! So glad to have my donut back, who cares about ginger bread after my painful 9 hour ordeal I couldn’t care less! Greatly appreciated.

      • MikeJ

        Well I actually got method #2 to work just now … After much frustration, and even buying a new SD card, I realized I wasn’t holding down the camera button long enough. Feel like an idiot but at least it’s up to 1.6. Yeh I`m a little behind still :)
