Sony Xperia Z


  • Sony Xperia Z with stock Sony Jellybean firmware.
  • It works on both locked/unlockable  bootloaders

  • First increase screen timeout to ten minutes Settings -> Display -> Sleep -> 10 mins
  • Next enable the USB debugging :  Settings -> Developer options -> Enable and Settings -> Developer options -> USB Debugging (check it)
  • Then enable install from “unknown sources”: Settings -> Security -> Unknown source (check it)
  • Next download the rooting package and save it on C:\
  • Exit all adb requiring apps like PC Suite, PC Companion, Flashtool etc as they will interfere with the rooting process.
  • Extract the Entire contents of the package (and not just one file) to some directory on c:\
  • Once you are ready with all the above connect phone to PC and execute  “runme.bat” from the location where the entire contents are extracted.
  • Press enter to start the process, as the device is detected the toolkit will start executing steps one by one.
  • Keep watching the command prompt and wait for the following to come up press the button to restore the data in your phone“.
  • At this point look at the device screen, an app will start, select Restore data.
  • Now you will get “if Restoring data is complete,” in the command prompt
  • At this point open Phone & dial *#*#7378423#*#*
  • Select “Service tests” in your phone operation.
  • Select “Display” (screen will turn white), the toolkit will now start executing some commands.
  • Now press power button to turn off screen wait for few seconds and press it power button again (repeat it a few time) till then keep observing the command prompt for outputs.

  • After that the device should automatically reboot
  • Thats it device should now be rooted


If your device has unlockable bootloader then after applying this hack the bootloader status will turn “Bootloader unlock allowed: No“. In that, case don’t worry the users have reported that doinga repair via SEUS will flash back stock firmware and turn this status to “Bootloader unlock allowed: Yes” (the same might also be achieved by flashing a stock FTF using FlashTool <yet to be confirmed>)
