A few days ago, Google pushed out the Android 4.2.2 (build JDQ39) update to the takju variants of the Galaxy Nexus. Takju Nexuses are the devices sold in the Google Play Store, whereas yakju ones can be found in other retail channels. Good news for those waiting on the latter - though a day after its sibling, we finally have the yakju OTA file that can be applied manually on any stock device, including unrooted ones with stock recovery.
To see what's new in Android 4.2.2, see New Android 4.2.2 Features: Toggle From Quick Settings, Better App Download Notifications, and Some New Sounds!
There is also a new radio in this update.
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
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."
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 07501b11ad3b.signed-yakju-JDQ39-from-JOP40D.07501b11.zip
You should see a progress bar, which will eventually hit 100%. At this point, your device is installing the update.
Reboot and enjoy! You are now running Android 4.2.2 on your Galaxy Nexus.
Here's the OTA, hosted on Google's servers: yakju build JDQ39.
