This is a guide that should work without problems if you carefully follow all the info I've listed below.

In order to make sure that you successfully update your device with this new Jelly Bean 4.2.2 OTA Update, then you should first read the guidelines below:

  • Make sure that your computer has all the Sony USB drivers installed on it.
  • Enable the USB Debugging from Developer Options menu.
  • Create backups of all the files that are currently stored on your device before starting the update.
  • If your phone is rooted, is running a custom ROM or it features any other customization then all these will be removed in the process and the Xperia ZR restored to stock Android 4.2.2 ROM.
  • Make sure that your device's battery power levels are over 50%. This will prevent it from switching off while the updating files are installed.
  • Use this guide only if you didn't receive the OTA update in your region. Make sure to check the Software Update menu under Settings> System> About Phone section. If there are no new firmware updates, then you can use this tutorial to install the new update.
