How To Root Sony Xperia Z

How To Root Sony Xperia Z

 

 

The Xperia Z is Sony's flagship phone for this year, and continues the screen size and resolution arms race with its 5in, 1,920x1,080 display. It also has all the specifications you would expect from a high-end smartphone, including a quad-core 1.5GHz processor and a camera with a huge 13-megapixel sensor. The display's Full HD resolution is the same as that of this year's HTC One, but the slightly larger screen size should make text more legible at this resolution. We found we could view web pages in desktop mode and still read all the page's text easily without zooming in. This is a trick that the HTC One also pulls off, but we found the Xperia Z's extra 1/3 inch screen size made reading more comfortable.

Warning:

Users are reporting that NFC is broken after this root method (easy fix by goroh_kun http://forum.xda-developers.com/showthread.php?p=39030221#post39030221)
if u had an unlockable bootloader device, after using this method the device will be detected as LOCKED or unlock not possible!!! (to fix this use http://forum.xda-developers.com/showthread.php?p=39178406#post39178406)
Try this at your own risk. The original authors & XDA community are not be held responsible incase your device is damaged in this process.
YOU HAVE BEEN WARNED
!! Rooting Can void warranty.



Before Starting Take a Look At This:


Requirements:
  • Xperia Z with stock Sony JB firmware (as of now tested on: 10.1.D.0.317, 10.1.D.0.322, 10.1.A.1.350)
  • works on both locked/unlockable bootloaders!
  • ADB drivers installed ((http://icxperia.com/doomlord/Flashtool-drivers.exe) incase u need to install drivers)
    IMPORTANT: if you are using Windows 8 you will need to check (http://forum.xda-developers.com/showthread.php?p=38878089#post38878089) to allow driver installation
  • Rooting Toolkit package provided below

Let's Root It: 

 

 

  1. increase screen timeout to 10 mins: Settings -> Display -> Sleep -> 10 mins
  2. enable USB debugging : Settings -> Developer options -> Enable and Settings -> Developer options -> USB Debugging (check it)
  3. enable install from "unknown sources": Settings -> Security -> Unknown source (check it)
  4. download the rooting toolkit package and save it on C:\
  5. exit all adb requiring apps like PC Suite, PC Companion, Flashtool, etc as they will interfere with the rooting process
  6. extract the ENTIRE contents of the package (and not just one file) to some directory on c:\
  7. 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
  8. press enter to start the process, as the device is detected the toolkit will start executing steps one by one
  9. keep watching the command prompt and wait for the following to come up "press the button to restore the data in your phone"
  10. at this point look at the device screen, an app will start, select RESTORE data
  11. now u will get "if Restoring data is complete," in the command prompt
  12. at this point open Phone & dial *#*#7378423#*#*
  13. select "Service tests" in your phone operation.
  14. select "Display" (screen will turn white), the toolkit will now start executing some commands
  15. 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
  16. u will see "transfer files to your phone part2", "installing busybox,su,Superuser,etc..." & finally "Cleaning up"
  17. after that the device should automatically reboot
  18. thats it device should now be rooted


Troubleshooting:

if your device has unlockable bootloader then after applying this hack the bootloader status will turn "Bootloader unlock allowed: No"
in that case dont worry the users have reported that doing a 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>)

ROOT WILL BE LOST BY DOING THE ABOVE AND YOUR INTERNAL STORAGE MAY GET WIPED!
SO DO A BACKUP OF APPS & INTERNAL STORAGE ON AN EXTERNAL SDCARD/PC




FAQ:
  1. will this wipe /data
    NO. since we are not unlocking the bootloader the /data partition will not be wiped
  2. do i need to unlock bootloader for this to work?
    NO.
  3. will i lose Bravia Engine 2 ?
    NO.
  4. does rooting without unlocking the bootloader still voids warranty.
    Not if you get back on clean Stock ROM
Thankz XDA TEAM!!!
