Android 2.2.1 hits the Nexus One, manually install it now

A new over the air update starting rolling out to the Nexus One and if you are impatient of waiting (like me) you can manually install it now. The build number is FRG83 and it updates the firmware version to Android 2.2.1. The file size is only 3.9 MB so it appears this is a minor update.

Details on the changes are limited at this point, but it has been reported that it patches the vulnerability that allows Universal Androot to work. Several users with alternative keyboards have reported some issues, but a simple reinstall of the keyboard app appears to resolve all problems.

This update is only intended for those running the latest stock version of Android 2.2 (build FRF91). If you have a hacked ROM installed, then please consult your ROM author and see if they have issued their own update.

To manually install Android 2.2.1 on the Nexus One, perform the following steps:

  1. Download the official Android 2.2.1 firmware for the Nexus One from Google’s server here.
  2. Copy the file to the root directory (aka not inside any folder) of your microSD card and name it update.zip (newb warning: not update.zip.zip)
  3. Power off your phone.
  4. Hold down the VOLUME DOWN button and power it back on.
  5. Wait for your phone to load the skating Androids screen. Scroll down to recovery and press the POWER button.
  6. When you see the “/!” symbol, press the POWER button and the VOLUME UP button at the same time. You should be presented with a menu and one of the options should be “Apply sdcard:update.zip”.
  7. Use the trackball to navigate to “apply sdcard:update.zip” and select it.
  8. When you see “Install from sdcard complete”, select “reboot system now”.

Enjoy and once you’ve had a chance to play with it for awhile let us know what you think. I installed it on my T-Mobile Nexus One in about 10 minutes and have not experienced any issues so far. I’ve read that users in other countries have also received this update so it should be good for any Nexus One model that is running Android 2.2, build FRF91.

    How about rooted but using stock rom?

    • http://Website jr.

      Did you not read the whole article? He writes to check with the author of your rom. Lol

      • http://Website Conrad

        Yeah but google made my rom… I just used a patched from xda to get it rooted…

        • http://Website Nick

          As with any other update, you must be on a completely stock rom to use the official updates, including no root.

          • Snafu77

            Not true.
            A stock rom is all you need to get OTA updates. OTA’s still come if you’re running a rooted stock rom.

          • http://Website Antwan

            What Snafu77 is right. You can be rooted as long as you don’t have a modified kernel because the update may check your kernel version against what its been coded to update.

          • http://Website kell

            Soon it will be Gingerbread and then Android Honeycomb! I can’t wait for the new features.

    • http://kenkinder.com/ Ken

      It appears that if you used Universal Root to root a stock ROM, but didn’t install a third party room, you do lose permissions on the “su” file.

    Really hope they have fixed the un-responsive home screen swipe bug.

      Use Launcher Pro!

        Launcher Pro did not help. So I used No Unlock to disable the lock screen completely. Hasn’t failed me yet.

        I do use Launcher Pro already but I just think it’s pretty major bug that should be fixed.

    This update might take away my super user privileges, even thou I’m not using vanilla android. I gained root thru that universal androot app. So ill just wait it out til I hear some feedback. Or until theyre serving gingerbread.

    Would love to get some color led options for the trackball! Why implement that hardware and not even use it?

    • Snafu77

      There is an app in the market that will enable the lighted trackball. I have K-9 set to use a different color light notification for every email account and that requires no special tricks. It looks like there isn’t anything much to enabling them, 99% of app devs including Google just dont do it. Of course that sucks for us. Roms have colored trackball support but IMO roms arent worth it. Root and tweak for me until I can do a 3 second boot and get the new sense ui.

    • http://Website Miguel

      It’s up to the developer to implement it. I use Gmail Notifier to make the Trackball bright gleaming red when I have new Gmail.

      The Facebook app allows changing the LED color also (I use blue), and SMS Popup allows changing the Led color for new SMS (I use Green).

  • http://Website nbecker

    Broke my outlook mail! Now, it just tells me I need to Activate device administration, which would allow application Email to ‘Erase all data’ amongst other things.

    Anyone know where to find the 2.2 for Nexus 1 so I can downgrade?

    • http://Website nbecker

      Well, it won’t let me downgrade back to 2.2 using the procedure in this article. Gave me some ‘assertion failed’ when I tried to ‘apply sdcard:update.zip’

      Before I did this I would reboot the phone, have 3G for about 25 seconds and then it would go to Edge. Now all good.

    Completely screwed tethering on a stock nexus one using t-mobile in Hawaii. USB tethering used to work well till today. Wifi tethering was always flakey – now it is even worse.

    Hey guys,

    I’m in Montreal on Rogers with a rooted Nexus One (used Universal Androot, but still on stock rom. I was running Clockwork Recovery 2.5.0.7)

    I got the 2.2.1 update yesterday. The update went fine. It took a while on the nexus boot animation (about 5 minutes), but besides that, it was painless.

    Things I noticed:
    - the update fixed the wifi issues I’ve been having since I got the phone. No more losing wifi connection!
    - Lost root access
    - seems to improve battery life but I need a few more days to confirm

    Hope this helps.

    • http://Website tekhnofiend

      Yes, I’ve also observed a significant increase in battery life. After 12 hours my phone typically would be dead or dying (with minimal phone calls during the day), but now it seems to have over 50% power after 12 hours. Has anyone else experienced this? Any idea on what’s changed with respect to power management?

      I’m in Atlanta with everything stock (not rooted, standard rom) on t-mobile. Update was flawless and just took a few minutes.

    Man I hope it fixes the issue with WiFi “obtaining IP address” issue – the one where “sometimes” it says connected, then shows “obtaining IP address” for a while, then disconnects/reconnects. This really annoys me – several routers I connect to work flawlessly, but many others dont – especially those in public places seem to be a problem.

    Anyone know if this update fixes this problem (assuming you have seen it also?)

    • http://Website Ed

      Upgrading to Android 2.2.1 did not fix the WiFi issues I’ve been having with my Linksys router at home, where the phone disconnects from the network, tries and fails to reconnect, and then marks the network “disabled”.

    Did this update let you change search engines under the settings?

      Hmmm.. Search has been removed from the main settings menu. But if you click the Google search widget you can press menu an adjust the settings there.

      I can find no way to change it though. I even installed Yahoo Search and I couldn’t get it to show up in this settings menu.

  • http://Website Elarella

    Since having Android 2.2.1, the changes that I have noticed so far:

    - 3G has become more robust. I used to be on Edge a lot, now I have 3g signal, even in elevators.
    - swype broke, but a simple uninstall and reinstall fixed that.
    - battery life had improved significantly. With all the twittering and web browsing I do, after 24 hours of usage, I still have 50% battery life left.
    - My internal memory of the phone increased significantly. As much as 20 mb for me.

    Those are the changes that I can account for that I’ve experienced personally. I am sure others can add to the list. Let’s here them!

    • http://Website GPugs

      I stated above that I thought I had fixed my 3G issue. However I didn’t. I am experiencing the exact opposite as Elarella. I am getting Edge where I previously was getting 3G. It might just be a coincidence, but this did start happening after the update to 2.2.1.

      • http://Website Elarella

        I was having the same issues with dropping to Edge even when I am out and about prior to FRG83, but ever since I set up my network this way, it’s been pretty reliable, even prior to FRG83:

        Settings -> Wireless & Network Settings -> Mobile Networks -> Network operators -> Search Network -> T-Mobile and ATT should be the options.

        I just chose Tmobile (or whoever is your provider) and I’ve been fine ever since. I do drop down to Edge every now and then, but that is usually at my townhouse where I am surrounded by power lines. Whenever I am out and about, I get 3G everywhere, even in buildings and rarely drop to Edge. BTW, I am located in Houston, TX so I don’t know if that has anything to do with it as well.
