Nexus 4 Android 4.2.2 OTA update - how to manually install it

Hey, hey! Last, but not least, the Nexus 4 joins every other Nexus device with Android 4.2.2 (JDQ39) finally starting to roll out now. How do you get it? Well, it doesn’t matter if you’re unrooted stock or rooted stock. You might be one of the lucky ones and can easily go to Settings, About, and Check Now for an update. If that doesn’t work, and you don’t mind getting your hands a little dirty, you can always download the official update and use the ADB sideload method.

How to flash an official Nexus update with ADB sideload:

1. First you’ll need to have the Android SDK installed and working.
2. Download Android 4.2.2 OTA for the Nexus 4 from Google’s servers.
3. Go to Developer options on your Nexus device. Enable USB Debugging.
4. Plug your Nexus device into your computer with your USB cable.
5. Open a command prompt (cmd) or terminal and make sure ADB is working with ‘adb devices’.
6. Once ADB is connected and working, type ‘adb reboot recovery’
7. You’ll see an Android with an exclamation mark.
8. Press Volume Up and Power at the same time to enter the stock recovery menu.
9. Select Apply update from ADB on your Nexus device.
10.  Type ‘adb sideload filename.zip’ into the command prompt or terminal on your computer.
    i.e adb sideload c:downloadsde8b8d101614.signed-occam-JDQ39-from-JOP40D.de8b8d10.zip
11. Sit, back, relax, and watch the update install.
12. If everything worked as intended, you should then be prompted to reboot your device,
13. Do so by using the Volume Up and Down keys to select Reboot System and proceed by hitting the Power button.
14. Your device should reboot.
15. Congrats! You now have Android 4.2.2!
