Last but not least, the Galaxy Nexus (Takju only at this point) is now starting to get the Android 4.2.1 update. The update is about 1.1MB, so it’s the same size as the Nexus 4 and Nexus 10 saw earlier today. The Takju Galaxy Nexus is the one sold in the Play Store. So if you got yours from the Play Store then check for that update, or keep reading and get the update to flash now.
This build is JOP40D as noted in the title of this post. Before trying to flash this update, you’ll need to be stock and on Android 4.2 build JOP40C.
Now that you’ve downloaded that tiny update from Google’s servers you are ready to continue:
Reboot your Galaxy Nexus into Fastboot mode (Holding Volume Up & Down with the Power Button)
After you see the “Start” press the Volume Up button to navigate to Recovery and press the power button
Next you’ll see an Android with a red exclamation point icon, then press Volume Up and the Power Button together.
Navigate to Apply update from adb”
Connect your Galaxy Nexus to your computer via the USB cable
You’ll need to have the latest Android SDK installed. If not download and install before continuing
Next open up a Command Prompt window in the same directory that the 4.2.1 update was downloaded to (i.e. downloads)
Type the following “adb sideload 1d62212ba0a9.signed-takju-JOP40D-from-JOP40C.1d62212b.zip” of course without the quotations.
You’ll see a progress bar, it will hit 100% then your device is completed with the update.
Reboot and Enjoy Android 4.2.1 on your Takju Galaxy Nexus
It may seem like a long progress to sideload the update, but it’s really not that bad. If you’re used to flashing ROMs and kernels constantly, this will be a piece of cake for you. But if you want to do it the old-fashioned way, a.k.a. waiting for Google to push it to your device you can try the following:
Go to Settings
Tap About Phone
Tap System Updates
Hit Check Now
If that doesn’t find the update, you can also go into Settings, Apps, and clear data for Google Services Framework. Once you get the update, let us know how it went for you in the comments below.
