How to Root Nexus 4

To root your Nexus 4 do the following:

  • Go to “Settings” -> “Developer options” and check “USB debugging”.
  • Turn off your phone.
  • While the Nexus 4 is turned off hold the Volume Down and Power buttons simultaneously until the Nexus 4 turns on and is in Fastboot Mode. You will know your device is in Fastboot Mode when it says START in green text.
  • Connect your Nexus 4 to your computer via USB cord.
  • Open command prompt on your computer and type “fastboot boot boot.img” without the quotes and hit Enter on your keyboard.
  • Your phone will now reboot and go to your home screen.
  • Once your phone is at your home screen, go back to command prompt on your computer (open it if you closed it) and type the following commands into command prompt one after another (be sure to hit Enterafter each command):
    • adb shell mount -o remount,rw /system
    • adb push su /system/bin/
    • adb push Superuser.apk /system/app/
    • adb push busybox /system/xbin/
    • adb shell
    • chmod 06755 /system/bin/su
    • chmod 0644 /system/app/Superuser.apk
    • chmod 04755 /system/xbin/busybox
    • cd /system/xbin
    • busybox –install /system/xbin/
    • exit
    • exit
  • Restart your Nexus 4.

Done! After you restart, you should now have root access. You can also now disconnect the USB cord, if you wish, and make sure to disable USB debugging mode.
