Update Google Nexus 4 to Official Stock Android 4.2.2 JDQ39 Firmware

Google Nexus 4 has received its own update to the Android 4.2.2 OS via OTA notification. But, not all users received this update and that is why I’ve created this post, for N4 owners worldwide to learn how to manually flash the Jelly Bean 4.2.2 JDQ39 OTA update zip easily without damaging their devices.

This is an easy to complete guide and you should be able to finish the installation of this update in no time. However, before we can begin the update process, you should read the preparation guide listed below. It will teach you how to successfully configure the smartphone so that you will be able to install Android 4.2.2 JDQ39 firmware update on Nexus 4 at the first attempt. Here’s what you need to know:

  • Do now try to use this guide with any other smartphone. It will work only with the Google Nexus 4.
  • The Nexus 4 should be running on the Android 4.2.1 JOP40D firmware. It doesn’t matter if the device is rooted or unrooted, as this guide will work either way.
  • In the ‘how-to’ guide you will find 2 different methods, one that teaches you how to flash the Android 4.2.2 Update via Stock Recovery, while the other one will use the Custom Recovery. So, choose the tutorial that matches your device’s recovery image.
  • Backup all important data by moving it on your device’s internal SDcard.
  • Since it is an update to stock Jelly Bean OS you shouldn’t lose any data in process. However, you shouldn’t blame us in case something goes wrong and you brick the device or you lose any important data in the process.
  • Make sure that you have the Android SDK installed on your computer. That’s the software that you will use in order to push the OTA update zip to your phone’s stock recovery.
  • Disable all antivirus applications from your computer as you wouldn’t such software to interfere with the updating process.
  • Make sure that you have the USB Debugging from Developer Options enabled on your phone. NOTE: You can find it in Settings app. If the USB Debugging isn’t listed, then you have to Enable Developer Options menu by tapping 7 times on the Build Number section.
  • Charge the phone’s battery so that the device won’t power off in the middle of the updating process.
  • Use the comments section to ask for more help in case you cannot complete the update.

These were all the steps that you had to take. Now you should continue to the tutorial guide and learn how to flash the update using Stock recovery. The ‘installation via custom Recovery’ is listed after the first guide.
