Last Updated: February 12th, 2013

Just after users began reporting that their Galaxy Nexus devices were receiving an update to Android 4.2 Jelly Bean (build JOP40C, to be precise), it looks like the manual update package is available for download. As could be expected, this coincides almost perfectly with the launch of Google's newest additions to the Nexus family – the Nexus 4 and 10.

Of course, it's worth reiterating that this is an update specifically for the Galaxy Nexus' Takju variant – that means only Galaxy Nexus handsets bought from the Play Store need apply (we're still waiting to hear about the Yakju variant). Your device should also be running build JZO54K before trying to install the update manually.

For those ready to download and install manually, the process is easy. If you have a custom recovery, just download the zip (linked below), move it to your device, and flash as usual. Those with stock recovery should keep the file on their computer, and just follow a few easy instructions:

Disclaimer: Android Police isn't responsible for any harm to your device - proceed at your own risk.

Step 1.

Reboot your Galaxy Nexus, holding the Volume Up and Volume Down buttons while it boots up. Once you see the fastboot menu and "Start," press Volume Up to navigate to "Recovery" and press the power button. Once you see an Android with a red exclamation point icon, press Volume Up and the Power button together, which will bring you to a new menu. Navigate to "apply update from adb."

Step 2.

Connect your Galaxy Nexus to your computer with a USB cable.

Make sure you have a recent version of adb that supports the sideload command (if you don't, download the latest Android SDK to ensure your adb is up-to-date).

Open up a command prompt (cmd in Windows, regular shell in Linux and Mac) in the same directory as the JOP40C zip file you've downloaded.

Type in the following:

 adb sideload e587de13bf8a.signed-takju-JOP40C-from-JZO54K.e587de13.zip

You should see a progress bar, which will eventually hit 100%. At this point, your device is installing the update.

Step 3.

Reboot and enjoy! You are now running Android 4.2 on your Takju Galaxy Nexus.

        Or just root and install it as soon as source drops.

      the optimism is strong with this one...

    • Moonkae

      I'm on Verizon. I'll have it in ~1-2 days. Not all of us are stuck. Please change to "Most Verizon Wireless users...". Thanks.

    • Christopher Bement

      Yeah right, my guess is 9. At any rate, when the sauce drops I'll have it.

  • Alvin B.

    So.... AOSP source soon?

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

      Hopefully tomorrow morning.

    Come on, bring us that juicy source code.

      I'm 4.1.2 yakju. Will be possible via OTA ?

  • http://profiles.google.com/tills13 Tyler Sebastian

    I'm getting errors. Script asserts are failing, yet both asserts should, to the best of my knowledge, pass. I'm on a Takju (Maguro), 4.1.2 (JZO54K) device... and it's failing.

    • David Stallard

      I'm the same - are yours related to Gallery.apk? Assuming it's related to manually updating to the 4.2 camera & gallery apps (couldn't wait any longer to try Photo Sphere) but haven't had a chance to play around to get it fixed. Let me know if you have any luck.

      • http://profiles.google.com/tills13 Tyler Sebastian

        Oh... it might be that keyboard...

        I've avoided the gallery thusfar, but I could only resist that keyboard for so long :P

        • David Stallard

          Yep, I reckon that's it. Wonder how we can get around it - surely it can't be that hard...

          • http://profiles.google.com/tills13 Tyler Sebastian

            I just did a factory reset... we'll see how this goes

          • Joel Stockley

            I am getting the same error, error 7. I have not touched my install apart from rooting it since I flashed the full ROM onto it about 2 months back when the latest takju rom came out sadly...

          • David Stallard

            I tried removing the Gallery completely but still get the same issue - dang it!

          • Joel Stockley

            I just noticed... the factory image on the google images page says 4.1.2, but the image it downloads is takju-jzo54k-factory-92830c0b

          • Joel Stockley

            Full wipe and re image of JZO54K and then applying the patch worked a treat :-D

            How can I re flash the 4.1.2?

          • http://www.facebook.com/samuelbelanger Samuel Belanger

            How do you do a full wipe and re image ?

          • Puleen

            Getting the same error as Joel above.

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

            Factory reset won't work if you modified part of /system. All factory reset does is delete data from /data.

            You'll need to restore the files you modified or flash a factory image.

          • David Stallard

            So I'll need to find a copy of the standard 4.1 GalleryGoogle.APK and flash that, THEN I'll be able to flash the 4.2 ROM?

        • http://twitter.com/tadejkolino Tadej Rudec

          Well, if you didn't backup the stock .apk and .odex, you know for the future what to do.

    This update ,wipe interna memory with photos band music?

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

      No, of course not.

  • tbonefsg

    still can't force update

    • Leo209

      I forced it. I tried just doing a manual update, and found nothing. I then went to settings, apps, selected Google service framework, and selected clear data and force stop. Then I checked for updates again. I had to do it like 4 times, but it finally prompted the download :D

      • Timothy

        This worked for me on the second try. Easier than adb. Although I don't know if it affects anything else.

        • The_Chlero

          usually, forcing the update by this method, some times users report problem with their google account, from just deleting some info to losing everything they bought from the google store.

          use it on your own risk

    Installed the zip through twrp and it said successful but after reboot I'm still stuck at 4.1.2?

  • http://twitter.com/sterpazook Alexander

    will there be 4.2 update for Nexus S?

    • http://twitter.com/briandsouza_ Brian DSouza

      wait for a few days and keep reading androidpolice...

    • http://www.facebook.com/OleIChristensen Ole I. Christensen

      No. Just read that Google now skip updates for the Nexus S model. Sorry.

  • Steven Van Bael

    I had the assert failures too initially. But then I completely reflashed 4.1.2 from the official factory images at https://developers.google.com/android/nexus/images#takjujzo54k and afterwards the update.zip applied nicely

    • Moshe Brevda

      Same here. Reflashed system image (link as above, unpack zip, ./fastboot flash system /path/to/system.img). Also needed to flash the radio as well.

  • personification

    Why no love for yakju?

    • http://twitter.com/mumarov Brzgw

      Google gives priority to people who bought from Play Store.

  • Caio Moreno

    And again fuc the yakju users =/

    how do i install this if i'm rooted?

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

      Same method, or if you're using a custom recovery, just flash it.

  • Joel Stockley

    I just noticed... the factory image on the google images page says 4.1.2, but the image it downloads is takju-jzo54k-factory-92830c0b same for yakju! https://developers.google.com/android/nexus/images

  • Espen

    Yakju 4.2 update availible from here! http://forum.xda-developers.com/showthread.php?t=1989033

  • Cédric Tremblay

    I encountered some problems.

    I had previously flashed the new 4.2 clock and camera on my 4.1.2 Galaxy Nexus.

    When trying to install the takju 4.2, it didn't work (saying something about assert failed : DeskClockGoogle.apk).

    Anyway, I reflashed 4.1.2 then flashed 4.2 and now it works quite well.

    • subramanianv

      Does it wipe data?

  • Pascal Welsch

    Status 7 after full wipe ...

  • Quan

    Followed the step-by-step guide, but when running the line from the command prompt I only get bunch of information about the Android Debug Bridge... Something like "about" section. Plus, my phone is stuck on "Now send the package..." screen... Help, pls!! :)

  • http://twitter.com/darrynite Darren

    yay yay yay..... I'm waiting for 4.2 on my galaxy nexus yakju.... should be getting it in 3 days just like 4.1.2 last time. yay yay yay.... i freaking love nexus devices.

    • http://twitter.com/mumarov Brzgw

      You have to wait, OTA isnt out for yakju.

  • Jeff Thomas

    I'm having trouble with "Once you see an Android with a red exclamation point icon, press Volume Up and the Power button together, which will bring you to a new menu." When I press Volume Up and the Power button, nothing happens. This worked fine on my Nexus 7, but not my Galaxy Nexus. Any ideas?

    • http://www.ninetwozero.com Karl Lindmark

      I noticed that if I made sure I pressed POWER before UP, then the rate of success was significantly higher.

      • Jeff Thomas

        That worked, thanks!

  • http://plus.ly/wallendiaz WallenDiaz

    my nexus is yakju...But I wanna know if I can install this version Takju without problems??

    • http://twitter.com/mumarov Brzgw

      You can't. Flash the takju image, then flash this.

  • Lulu

    Probably a lame question, is this rooted and unlocked?

  • bholub

    When I plug my phone in normally the USB driver works fine (both for file transfer and testing/developing apps) yet when I plug it in under recovery mode (Step 2 in this article) the device isn't recognized. Device manager does show a yellow exclamation for Other Devices -> Galaxy Nexus. Any thoughts?

    • lamah

      Download and install pdanet

      • bholub

        thanks for the reply. i actually got it OTA this evening before I got a chance to get back into it tonight.. i just should have been more patient :)

    • Reza

      same problem here
      so there is no Apply from ADB in recovery menu

  • Josh

    My Galaxy nexus got the update notification, I started the download and when it finished the system restarted and got stuck on the android with the red exclamation mark for about 5 minutes, it then restarted as its previous version android 4.1.2 and keep saying the OS is up to date.... :(

    • kith

      same thing happened to me did you figure out what to do?

  • Yumi Faeldo

    What will a Takju build to my Yakju build GNex? Damn I should have just flashed Takju when I left yakjuxw or whatever that was.

  • subramanianv

    Here are the apks for 4.1.2 Clock and Keyboard, if anyone is still searching for it. Waiting for hours to get OTA system update and only to see it fail, sucks.

  • RockMSockMNY

    I got the notification for a system update, followed the instructions to restart on screen, but when the phone powered down, it never powered up again. I tried turning it on, but the power button did not work. After a few minutes, I was forced to remove/replace the battery to get my phone to turn on. Long story short, phone works perfectly fine, but I didn't get 4.2--I still have 4.1.2, and it says "up to date." Not sure what this means....
