Froyo 2.2.1 Update Rolling Out to Nexus One Owners, Manual Install Available

Nexus One update

The Froyo 2.2.1 update is rolling out to Nexus One owners right now and should be for the next few days.  Not much yet on what the update contains as this is breaking news.   As soon as we know more about what the update has, we will update this post! You can pretty much bet on this breaking root, but if it’s worth the risk for you hit the source link for full manual install directions.  Let us know what you think!

    Would love to know what’s in it. Hasn’t appeared on my nexus one yet, hopefully soon.

  • David

    I got it last night. The only thing I noticed that was different was it broke my N1 Torch app.

  • Jason Harris

    Hopefully it fixes the fact that anything installed on my SD card won’t update unless I move it back.

    am not able to update..!! when i go into recovery mode and after the exclamation sign, i press the VOLUME UP key along with POWER and it goes through like this:
    updating…
    verifiing signatures
    verifying signatures failed…
    installation aborted…

    MY version is as below:

    Android Version: 2.2
    Baseband version 32.41.00.32U_5.0.8.00.04
    kernel version: 2.6.32.9-27227-g3c98b0d haley@m4-dev#1
    build number: FRF91

    Please HELP!

    I have the same version of Android – Base band – kernel and buil number.
    I’m in trouble installing too. :-)

  • Ice007

    I found the right instruction for installing update.zip:

    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)

    But my update failed when the Verifying process start…
    I see this error on my N1:

    — Installing from sdcard…
    Finding update package…
    Opening update package…
    Verifing update package…
    E:failed to verify whole-file signature
    E:signature verification failed
    Installation aborted.

    Please help me… :-(

      wen u name it just name update not update.zip dat helped me

    • ftpeddy

      Got the same error as Ice on my AU-Voda N1 :(

  • williamthrilliam

    You need root to install manually.

    • Alex

      Root is not required for a manual install. If you’re using a custom recovery you will not be able to use the version linked on this site as it is an official update, signed by Google. You will need to head over to the xda forums, and locate the manual install for custom recoveries.

  • Ice007

    Thank You….I have rooted but the error is always the same… :-(

    Yep, just got mine. The phone is rooted but I had no problem upgrading and Android version shows 2.2.1

  • tinkybabi

    Just installed mine and had no problems. Also, cant tell the difference between the 2.2 and 2.2.1, everything looks the same…. nexus one user!

  • scott

    Just got the update. Right away I got an alert to ‘Activate device administrator’ from my work Exchange server. Also, maybe its my imagination, but all of the home screen icons look a little bigger.

  • Jamie

    Just went to do a manual install when it popped up and said there was an update available. Great timing. :)

    Aussie Nexus One.

  • Paladin

    But will this update break root, if said root was obtained by something like UniversalAndRoot, and not by unlocking the bootloader and installing a custom ROM?

    My phone downloaded the update but i’ll put off install if it does.

    As for the failed installs, i think you have the Vodafone version of the Nexus.

    Got my update last night. Haven’t seen what the difference is tho……if someone finds out….please post.

  • cwen

    Received my auto update yesterday. No problems for me. Only thing I noticed, and this may have come out before, is that while typing the number keyboard will auto appear if you hold your finger on the keyboard and move above the letters. Pretty convenient. Let me know if you discover anything else.

    Just a note to Swype beta users – your Swype will not longer work when you get the update.

    To get it working again do this:

    1. Uninstall Swype.
    2. Run the Install Swype app again.
    3. You’ll have to enter your user/email and password again.

    NB. Probably shouldn’t do it if you deleted the Install Swype app. :p
