Last Updated: September 26th, 2011

Nexus One owners, you've got an update waiting for you this evening. The version number is 2.3.6 (GRK39F), which will apply right over 2.3.4 GRJ22. If you still haven't gotten yours OTA, we've got the download link and instructions below.

As for the changes it brings, we haven't gotten much to go on except for the following blurb: "important bug fixes and security patches." If it's anything like the Nexus S 2.3.6 update, it will contain a fix for the voice search bug (was this even a problem on the Nexus One? Speak up).

Installation instructions

Note: If you don’t have GRJ22 (2.3.4), then head over here and install GRJ22 first, then proceed below.

Note: This may or may not work if you're rooted.

As always, proceed at your own risk.

To download and apply the update to your Nexus One manually, follow the following steps:

  1. Download the update file from Google's servers GRK39F-from-GRJ22 (here's our direct download mirror in case it goes down) and rename it to update.zip (make sure it’s named update.zip and not update.zip.zip if you’re using Windows and have it set to hide file extensions).
  2. Move the file to your SD card’s root using your favorite method – the easiest way is probably mounting the phone as disk using a USB cable.
  3. Reboot your phone and when it starts booting back up, hold down the Power and Volume Down buttons.
  4. If you see Bootloader, select it.
  5. Select Recovery.
  6. The phone will reboot into recovery but first it’ll show an exclamation point and a triangle. At this point, mash the Power and Volume Up buttons a few times until the recovery screen shows up.
  7. Select Apply sdcard update.zip, which should start the update process.
  8. Reboot and enjoy Android 2.3.6.

Thanks, Michael!

    Tried with Rooted Nexus S GT-I9023 running Stock 2.3.4, but did not succeed. Looks like I will have to unroot it. :|

      The article starts with "Nexus One owners"..

    • Mike

      "GoogleNexus One2.3.6OTA" pretty self explanatory ...... of course it wouldn't work on a Nexus S.

      • Mike

        Artem, I also found it easy to use a file explorer and rename the file then move it to root. That's the way I always do it, no computer needed :-)

      Lulz. Nexus S.

  • Shadez

    Oh yeh. Thanks for pointing it out. Got a bit jumpy.

  • backslash

    Since Gingerbread it isn't necessary anymore to rename the file.

  • epool86

    horay.. done and my Nexus One now running the latest android version (again) ;p

    • BigVDawgy

      Does it break tethering?

      • http://www.AndroidPolice.com Artem Russakovskii

        From what I've read so far, it doesn't.

    I just got the 2.3.6 update for my nexus s as well

  • munash

    Thanks. Just received it OTA.

    Btw: Try triple tapping the Android version in the About phone screen. It'll pull up a "Zombie art by Jack Larson" picture.

    Does someone know where to find the same file for the Nexus S?

    Because I still don't have received it by OTA (I'm from Belgium...).


  • Supsandroid

    And this is why my next phone will be a nexus phone and the e4gt is going back to sprint

  • Manish

    Signature error once again! I'm fed up with this error, not even a single time this worked except for the 2.2

    did any1 have same issue and resolved??

  • Ariel

    This update is great i notices a few changes:

    -Voice search enhanced, now I can do whatever I want (except oppening apps) with it.

    -Smarter GPS: Now you can keep it activated without it beeing used unless you open maps. Usefull if you dont want to activate it just when you need to use it.

    -Space bar changed on form filling sections: The space bar on keyboard now gets divided into two, the right half is a button that allows you to go to the next filling square on forms.

    -Tethering fixed.

    Any other changes noticed?

    Its actually caused a bug which was existing on the Samsung Nexus S onto my Nexus One now since the new update, on my n1 the wifi keeps disconnecting every 2mins or so and reconnecting such a pain it was fine before the update, ps my 2.3.6 update was accepted over the air.. i didnt do it manually.. "Google Fix this"

    If you get an error message when trying to use your wifi after rooting your Android device, the reason is most likely that you’re running on a 2.6.32 kernel version (that has the serial port enabled) and flashed a boot image that was compiled with the bcm4329.ko kernel module what doesn’t match that kernel version.

  • https://bexton.net/ Bexton

    Once again me. For all whom it may be of interest: I made a Superboot fork - especially for the Nexus One on GRK39F. I compiled the boot image from the stock GRK39F source of my own N1 and included the latest Superuser.apk, as well as the latest su binary. If you want stock and root, i highly recommend to flash this boot image: https://bexton.net/2011/10/12/bexboot-root-nexus-one-passion-grk39f/

  • Mnm

    I downgrade my version from grj90 2.3.5 to grj22 n tried to flash the update.zip (grk39f) but i got status 7...whats the problem...smbody help me...please...

  • Felix

    2.3.6 has mess with a few things :
    Desk dock not been detected, i have the original headphones but the microphone does not work, battery is taking hours to charge, the tethering Does work. My phone got service by HTC less than a week ago so I'm pretty sure that the issues are because of the update good luck!

  • http://nil iamsra

    Hi....asking for help to install 2.3.6:
    -Original ROM (i hope this is correct way to write)

    Four times I got a notice to update and each time it failed. The end result is printed below.
    If you know how to please give step-by-step instructions. I'm not tech savvy. Just know how to make the best of a phone:

    ...result is:_

    Finding update package...
    Opening update package...
    Installing update...
    Verifying current system...
    assert failed: apply_patch_check ("/system/app/twitter.apk".
    E: Error in /cache/d323ca384aaa.signed-passion-GRK39F-fromGRJ22. d323ca38.zip(status7)
    Installation aborted.

    Just finished trying the method given by Artem on this web-page. Failed again. But the result is slightly different. This time the error is:
    E: Error in /tmp/sideload/package.zip (Status7)
    Installation aborted.

    PLEASE Help

  • gordon

    tried to update nexus one on vodafone uk, from 2.3.4 to 2.3.6, but on installing update you get;
    failed to verify whole-file signature, signature verification failed
    installation aborted.
    tried both links above and both do same, folowed the instructions to the letter
    anyone can help me with this

  • Neil

    have you succeeded yet? i have the same problem.

    • gordon

      i sent the other back for all messing round they gave me, so i started again with phone off them i got another gn1 and it only had 2.2.1 on, after 4 days no update so rang vodafone and htc, they said it would come in random order no idea when, anyway i kept telling it to up date but said it was upto date, and tried all recovery etc, still same problem erro with them all someone said on a site unlock bootloader, so i unlocked bootloader, and then used passimg.zip for version 2.2.1 it updated the firmware but wiped everything not that it was a big deal rebooted the phone and within an hour or less OTA update 2.3.4 came down followed right after with 2.3.6, it updated ok, seems it could have been version of firmware on it, that was stopping it updating or just happen that the update was on way, anyway the 2.3.6, is ok i lost pinch on photos, and it seems to loose wireless and mobile network, but the wireless bit could be when its not being used it goes to sleep, and the phone network could be bad signal i know vodafone say my phone did not register correctly on there network so i sorted that, the version of rom/firmware is GRK39F now. i found the 2.3.4 was better not crashing etc, the problems have with 2.3.6 are: moving apps from phone to sdcard fails you sometimes have to do it twice, the wireless signal drops off then comes back, the mobile network signal seems to do same, the pinch on photos has gone but not on websites, i installed an app to use for viewing pictures in place of one on phone this gives me back the pinch to zoom etc, app store/market force closes odd times, no problems with keyboard or predictive txt that works ok, camera works ok. so far just few minor problems above.

  • gordon

    if i could turn it back to 2.3.4 i would much better and everything seemed to work ok, plus seems very little difference apart from 2.3.6 bugs,
    i could install custom rom. may do that later if can be arsed.

  • manish

    I got the Signature verification failed error, while updating from 2.3.4 to 2.3.6.
    Is this happening because my phone is not rooted? If this is the case, and somehow if I will get success to install 2.3.6, will my phone be rooted or it will still be as it is.
    Any kind of Help is appreciated.
