Nexus One Android 2.2.1 update

There have been so many updates in the past week that it seems like every Android device is deciding to receive an OTA just to not feel left out. 

This time, Google's own flagship device, the Nexus One, receives an update to its OS. Here is the information on the update, courtesy of Devastatin from the XDA forums:

  • Android version: 2.2.1 (!!!!)
  • Baseband version: 32.36.00.28U_4.06.00.12_7
  • Kernel version: 2.6.32.9-27240-gbca5320
  • Android-build@apa26 #1
  • Build number: frg83

Update instructions after the break. Thanks, Anthony!

1. Download the Android 2.2.1 firmware for the Nexus One Here
2. Rename the file update.zip and copy it to your microSD card via USB. [Note: make sure the file is named update.zip and not update.zip.zip.]
3. Power down your Nexus One
4. Hold down the “Volume Down” button as you power the phone back on.
5. A screen should appear showing your phone’s system searching for various files. Scroll down to “recovery” and press the “Power” button.
6. When you see the triangle with an exclamation point symbol, press the “Power” and “Volume Up” buttons at the same time.
7. From the menu that appears, select “Apply sdcard:update.zip.”
8. When the screen displays “Install from sdcard complete” select “reboot system now” and wait for the phone to power back up. (this will take a long time)

Just a software update as far as we know. We have heard that once it is updated, some of the 3rd party keyboards have issues. Swype was reporting an issue while not working and Swiftkey wasn't predicting words. So if you do this update, watch out as you may not be able to use your favorite keyboard right away. 

This is a very new update, so we'll keep you up-to-date as we hear more. [XDA forums] Thanks to Anthony and Devastatin for providing info!

Has anyone gotten this via OTA or is it only a leaked rom?

I received this prior to seeing this post. Should get it soon, if not already

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

I think they were in reference to the remark of "it seems everyone is pushing OTAs this week."

Yeah I'm pretty sure they made it clear it was for the nexus only and I don't see anyone asking other wise but Thanksgiving for clearing that up for us. So is there a change log?

Soooo does 2.2.1 fix all the streaming audio issues in 2.2? Let's hope so.

 
Posted by icebike
September 23, 2010 - 20:501 year ago

Not seen any of those, and I stream quite a bit.
Can you explain what you are seeing?

Basically, people were complaining about 2.2 not having native AAC+ encoding, among other file formats, thus reducing sound quality.

Yes I would love to see a change log, I really want to see what has changed or been fixed with this update. Especially if Swype sometimes gives issues, I love Swype and I'm hesitant to perform the update if it will not let me use Swype!

Reinstalled swype completely (as I seem to have to do on any update), and everything works fine again.

Is this for the T-Mobile version, the AT&T version, or both?

I have an AT&T version and got the OTA update about an hour ago. I haven't played with it too much, but early indications suggest that they have fixed, or at least bettered, the wi-fi sleep issue.

My Microsoft Exchange account now allows the administrator to make changes to my device. I.e. I can no longer unlock with a pattern, have to use a PIN or password.

If you have root access on your device, you can delete that version of Exchange email by doing the following:

adb remount
adb shell
mount -o rw,remount /system
rm /system/app/Email.apk

then install an earlier version of Email.apk. Email me and i'll send you a copy. I hate the security update in Exchange email, so I just counteract it by using that version. (christopher3712@gmail.com)

PS You can also delete Email.apk by uninstalling it through Titanium Backup. Remember, this is only if you have root access (because it's on the system level).

I don't see why a pattern lock wouldn't be enough. I mean as long as you have an entry limit set.

If I have a rooted nexus one, will this new version of the os unroot my device?

I tried to update it via manually doesn't work. Is this for rooted nexus ones or stock? Has anyone received it OTA?

 
Posted by dhawk

I have also failed to update manually... would it work to rename the file just (update) and not update.zip since it is already a zipped file? Do not want to try it without confirmation.

Definitely, most of the time file extensions are hidden in folders view. If you see update.zip in that file, but no extensions in other files, then delete the .zip and retry!

I have a rooted Nexus with the one click root installed. Should I unroot the device before I install the OTA update?? If I unroot the phone will I be able to use the one click root to root the phone again???
Man plenty of roots in that question.
Thanks

I'm having errors installing as well, rooted Nexus One with unlocked bootloader, trying to install the sdcare update.zip from clockworkmod recovery it gets to the part that says talks about verifying something on the sdcard (after verifying system package) and says update aborted. Any ideas? I downloaded the file to my PC and transferred to the root directory of the memory card with a USB cable

Been seriously considering acquiring a lightly used Nexus for some time. And they're getting less expensive when dummies see "the new shiny"...

Appears at least for me to resolve the issue with the wifi adapter dropping any data connection when the screen is off. That nagging wifi problem finally seems to be gone!

I'm on Tmobile with a stock, unrooted, locked bootloader N1. Doing repeated checkins since 2am... still no update yet =/ blah. I guess google has us in Organizational Units serverside and mine hasn't been applied the update yet.

Thanks, I did end up doing that about an hour ago. Worked fine without a hitch, despite my irrational worry.

Loving the new update; finally got my exchange email account to work.

Are you guys having trouble with SwiftKey? I haven't updated yet, I don't want to lose my auto predict... Who knows how long a fix could take...

I just updated manually, and haven't had an issue with Swiftkey. Didn't even need to reinstall it.

Only worked after a reinstall. But yeah, then you will definitely lose your auto predict stuff.

If I manually updated to FRF91, will I receive an OTA for FRG83? Or do I need to manually update again?

@TaeKwonDonkey If FRF91 isn't rooted and signed I believe it will update OTA.

I should of asked first. Is this for the AT&T or T-Mobile Nexus One?!! Holy Moly!

Re Nexus One and Sywpe issues with Android 2.2.1

At first Sywpe did not work after a manual install of Android 2.2.1. I tried Sywpe uninstall and reinstall but no success. I finally tried Settings, Applications, Running services, and then keyboard settings for the keyboards you have. Mine was Smart Keyboard Pro. Each keyboard seems to list a Swype setting which only requires the "check mark" to be set and then you are good to go.

Thank goodness, as I really enjoy Swype and I can type very very fast with it. I would gladly pay for Swype if they will ever change their business model and list it in Marketplace.

Just did the manual update on my N1 with AT&T. No problems installing it, the reboot took an eternity it seemed like. Playing around with it a little bit makes me think that the google apps like market and chat are snappier. This may just be me wanting them to be faster, but even so I am happy. Keep the updates rolling google!
