A couple of hours ago, Google started rolling out the Android 4.2.2 update to a very limited subset of Nexus devices (build JDQ39). At this point, almost nobody can get the OTA pulled by going through the Settings screen, but don't worry - one of our loyal readers extracted the OTA url for the Galaxy Nexus and sent it over to us (great work, Daniel Koch!).

For now, we only have the link for the takju Galaxy Nexus variant, i.e. GNex handsets bought from the Play Store. Once we get the yakju build, we'll update this post.

If you're not sure whether you have a takju or yakju variant, download Nexus Update Checker from the Play Store and see what it says.

What's New?

We don't have any reliable information at this point because Google hasn't pushed the 4.2.2 files to AOSP yet or published any changelogs. We suspect the Bluetooth bug has been fixed, but are unclear what else has changed right now.

There is a new radio in this OTA.

Prerequisites

Your device should be running build JOP40D before trying to install the update manually. If you for some reason don't have JOP40D, Google has it available in factory image form here.

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
  • have the stock recovery, keep the zip file on your computer and follow a few easy instructions below

Manual 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 zip file you've downloaded.

Type in the following:

 adb sideload 472aafeb9fe3.signed-takju-JDQ39-from-JOP40D.472aafeb.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 4.2.2 on your Galaxy Nexus.

    Hi. What about root, custom kernel and custom recovery?

    What should we bring back to stock before installing manually or OTA?

    • Jason Banich

      For root: The update will unroot your phone, but you can use OTA Rootkeeper to backup root and restore it after the update: https://play.google.com/store/apps/details?id=org.projectvoodoo.otarootkeeper&hl=en

      For custom recovery: Custom recovery can stay, since the instructions above say you can flash the zip through custom recovery :P

      For custom kernel: Not entirely sure on this one, someone else will have to answer

  • MisterX

    I've found one other new thing. Android now asks to accept the RSA key of the computer before enabling USB debugging

    http://picpaste.com/pics/Screenshot_2013-02-12-10-27-58-XghkxREk.1360662129.png

    (sorry it's in french): Authorize USB debugging
    Digital fingerprint of the computer's RSA key: ...

    Always authorize that computer

    • kr

      usb debugging is not working for me after the upgrade, My device is showing as "offline"
      What could be the problem??

      adb devices
      List of devices attached
      XXXX offline

      • Scott Kennedy

        Update to the latest version of adb.

        • chandradithya

          Can someone point me to where i can fetch just the new ADB + fastboot files? (Without downloading the full SDK)

  • http://profiles.google.com/stevoo82 Stelios Philippou

    I can confirm that this actually works.

    i have just flashed and i am running 4.2.2 JDQ39 ...

    Now ill need to get to my car and see if the bluetooth is fixed !!!

    • Larizard

      so is it fixed? o_o?

      • chandradithya

        This suspense is killing me.

        • http://www.google.com/profiles/MetalMessiah78 José Gómez

          A2DP still sounds like $hit. It was not fixed. This was the thing I was looking forward to the most. Don't know if they fixed something for people having problems with it disconnecting, but they didn't do anything to fix the sound quality.

          • Ami Black

            i found using beats audio drivers sometimes fixes the a2dp bull$it sound quality on my device, about to try it again on 4.2.2 and see if it fixes it a second time around... never did get the audio "lag" fixed though

          • http://www.google.com/profiles/MetalMessiah78 José Gómez

            Did the Beats audio driver fix the poor A2DP sound quality? If so, do you have a link on how to install it?

    • legend618

      are you running it on a nexus 4?

  • al v

    I wonder if this works for the n7

    • Jason Banich

      No, do not flash it... Would be a nice way to brick your N7

      • al v

        Damn it, thanks anyway, I feel outdated now , lol

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

        It wouldn't brick because it wouldn't apply the update.

  • springyman

    Question, the above technique, does this wipe your phone? What if you have a custom kernel on the device? Does it over-write it with the one included in Build JDQ39?

    • chandradithya

      The above technique doesn't wipe the phone data and i'm not sure about your 2nd question. I normally flash stock radio, recovery and kernel to be on the safer side while applying an ota

    • Alan

      Having just flashed this myself I can confirm that it doesn't wipe anything.

  • t-6

    Hm, getting an error while trying to install it with CWM Recovery 6.0.1.9:

    "assert failed: File_getprop (" /system/build.prop", "ro.build.fingerprint") == "google/takju/maguro: 4.2.1./JOP40D/533553:user/release-keys" || file_getprop ("/system/build.prop", "ro.build.finterprint") == "google/takju/maguro:4.2.2/JDQ39/573038:user/release-keys" E: Error in /sdcard/0/472aafeb9fe3.signed-takju-JDQ39- from- JOP40. 472aafeb.zip

    (Status 7)

    Installation aborted

    Any thoughts?

    • Dano

      I have the same situation. Maybe because web have yakju devices

    • heat361

      Usually if you have changed something in build prop It won't work to flash it. You'll have to restore your old build prop.

  • noreply

    I just updated with sideloaded clockwork mod, works like a charm. After you flashed the OTA and choose restart in CWM it ask if you wanna try and keep root, answer yes and root will work even after update.
    Should be same thing for custom kernel (NOT TESTED)

    The update does not wipe anything!

    • springyman

      Did you come form a stock kernel or a custom kernel?

  • Duncan Booth

    "If you're not sure whether you have a takju or yakju variant, download Nexus Update Checker from the Play Store and see what it says."

    Alternatively just open Google Maps which you probably already have installed then go to Settings/About and the fourth entry down tells you if it is takju or yakju (or something else).

    Us on Verizon just sit back watch and admire! Hope you GSM guys enjoy!!

      Just wait for the dev community to startt using it.

    • FrillArtist

      At least you have LTE, eh? Lol.

    • Elias

      you spelled "envy" wrong

  • http://www.facebook.com/dextor Sebastiano Gottardo

    they didn't fix the camera rotation issue. what's wrong with them? :/

    • http://www.facebook.com/dextor Sebastiano Gottardo

      but now it's not possible to adjust the volume while you're in the lockscreen. that's good, no more accidental silences or ringer volume spikes.

      • http://www.facebook.com/dextor Sebastiano Gottardo

        also, you can turn wi-fi on/off by long-pressing the quick setting button. the same goes for bluetooth.

        • Bleakvision

          Damn, should be the other way around, meaning a long press should go to the preferences...

          • Razormike

            ^^^True lol

          • kr

            usb debugging is not working for me after the upgrade, My device is showing as "offline"

            adb devices

            XXXX offline

            What could be the problem??

        • Razormike

          That's pretty nice, how did you figure it out? Did it prompt you, or did you just try it. Is there any difference in screen colour?

        • Kristoff119

          Finally, I thought the quick settings was pretty pointless on the quick part, but they have done well!

    Anyone getting Error Status 7?

    • robert svantner

      Yes. I get error 7. Anyone know why ?

  • http://www.facebook.com/FrankRustyak Frank Rustyak

    Why do we need to be on build JOP40D (4.2.1) first? What difference does it make if we're on 4.1.2?

    • chandradithya

      Because this isn't a full OS upgrade from 4.1.2 to 4.2.2 instead its just a delta update that adds / modifies the files already present in 4.2.1.

      You can go straight to 4.2.2 from 4.1.2 when google releases the factory image at the cost of wiping your data.

  • Stephen McGann

    Is anyone else having a problem with the facebook App and alternate login accounts?
    And is it possible this update will fix it. Because it's irrating the crap out of my wife

  • Rajat

    I can't understand as to why Google / Samsung won't update the kernel for Galaxy Nexus to 3.4 ?

  • mrsbelpit
    • http://www.google.com/profiles/MetalMessiah78 José Gómez

      No Google Now widget in this update unfortunately. I'm sure it'll come in an app update through Play. Google usually updates their apps on Wednesdays. Hopefully we see it tomorrow.

  • Juan

    Does anyone has the file for Yakju phones?

  • bitbank

    4.2.1 broke Wiimote connectivity. Does someone know if 4.2.2 fixes it?

  • Diogo Hayakawa

    This icon (Miracast I think?) keeps showing on Google Music, Youtube, and all that, but nothing happens. Is this 4.2.2 related? Stock Galaxy Nexus.

    • Elias

      Same dialog also appears if I have a bluetooth a2dp device connected to my N4. You probably have some kind of program on your pc which makes your gnex believe your computer can display media (miracast, dlna, upnp?)

    'adb sideload' doesn't work even i tried with latest android development tool :(

  • myself

    Correction: Hold Power button dow first, and THEN press VolumeUp, in that sequence.

  • keith

    Just received the 4.2.2 update OTA. 47mb in South Carolina. No issues found yet.

  • MostCuriousG

    Just got the 4.2.2 update on my GNex (Yakju) by restarting the google services framework. Had issues installing initially but managed to copy the zip file to the root of the SD card and manually updated. Sweet!

  • Elias

    I still don't understand why they haven't made it available for the N4. Mine is still running 4.2.1. Maybe they're fine tuning it for this specific device before release?

  • REAL6

    Sorry for the noob question. When you get to Recovery. Then what? Because i don't see the "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."

    Thanks.

    • REAL6

      It just goes to the recovery menu.

  • jack

    when i type in the sideload command nothing happens just a list of random stuff apears in cmd and thats it usb debugging is enabled and i downloasd the lastest sdk plz help!

  • geneviève Arbour

  • bibham gupta

    I am facing 3G connectivity problem after upgrading my galaxy nexus to android 4.2.2.
    The phone is working fine with wifi.
    When I restart the phone, it is getting connected to 3G but only for 10 sec (approx)
    After that there is no data connection.

    Please help.

  • saurabh

    i have a stock 4.2.1 takju gsm GN!! rooted and cwm installed .. should i directly flash the given zip ??

  • mike

    I'm finding that 4.2.2 is less smooth when transitioning from the main screen to the menu there is a lot of lag compared to 4.2.1 and battery is dying faster. Bluetooth in car problem is fixed! But overall phone is slower compared to 4.2.1

  • Valmir Xheladini

    Guys, i have s.galaxy nexus (yakjuxw) and im still on 4.1.1. What do u think, where will the updates come to us ? We are like 4 updates behind.
