Before starting the installation, make sure that you read the guidelines below:

  • Use this post only for the Google Nexus 4 that runs the Android 4.4 KitKat factory image.
  • The Nexus 4 has to be on an unlocked bootloader, obviously.
  • Make sure that you have the Android SDK installed on your computer. Since you've come from the KitKat installation guide, then we can safely say that your PC has the Android SDK with adb and fastboot files present.
  • Enable USB Debugging from Developer Options.
  • Check the phone's battery charge level and make sure that it is over 5o% before starting the root process.
  • For the root to be achieved, you will first need to flash the TWRP custom Recovery.
    - all the steps are found under a single how-to guide below.
  • Backup any important data files that you have stored on your device. This is only a precaution, as the root process shouldn't wipe any files from your device.
  • This post is destined to be used by more advanced users, so you shouldn't blame us in case you brick your phone or lose any data in the process.

Great! I used this a month ago to root Kitkat, and today, I used it again (with the newer files, of course) to root 4.4.2. Very nice job!
