So guys I have got root on the newest firmware 12.0.A.2.245 / 254!


Since Sony has patched our beloved perf_event exploit (with which we rooted 30+ Xperia devices) I had to find an alternate way... so I did the smart thing, just used the kernel on which the exploit works, root the device and flash back the newest kernel!


THIS WORKS ON BOTH LOCKED & UNLOCKED BOOTLOADERS!


once again thanks to all the users who donated this device to me!

[ NOTICE ]

THIS IS ONLY FOR THE XPERIA SP (C5302/3) FW 12.0.A.2.245 / 254!

DO NOT USE IT ON ANY OTHER VARIANT/FIRMWARE!

[ how-to ]

  1. Download the three files from the download section below
  2. open FlashTool and flash the XperiaSP_C530X_12.0.A.1.257_KernelOnly.ftf - 6.78 MB file, this is JUST the kernel of an older firmware which was rootable
  3. now once flashing is done reboot device and connect to PC in usb debuggin mode
  4. CLOSE FLASHTOOL <<< VVVIMP STEP
  5. extract the file DooMLoRD_Easy-Rooting-Toolkit_v18_perf-event-exploit.zip to root directory on c:\
  6. execute runme_ file corresponding to your OS on desktop PC, this will execute a SPECIAL version of my easy rooting toolkit <<< VVVIMP STEP
  7. the above step is crucial! if you use any older version of the toolkit then IT WILL NOT WORK!
  8. after rooting is over the device will restart
  9. you can verify if device is rooted by checking for SuperSU app (it is the newest version)
  10. once thats done now power down device and open FlashTool again
  11. now flash XperiaSP_C530X_12.0.A.2.254_KernelOnly.ftf - 6.95 MB OR XperiaSP_C530X_12.0.A.2.245_KernelOnly.ftf - 6.95 MB (depending on your firmware) file to get back to the true kernel for the firmware
  12. thats it after flashing is done just disconnect and power on device and enjoy rooted phone!

tested.....working.....wow that was fast!!!!!
ofcouse it will work! i tested it 2-3 times on the device you guys donated to me :D

and when i have time these things generally move fast ;)


P.S.: i have rooted numerous Xperia phones, right from Xperia X10 (GB-2.3.3) to Xperia Z (4.2.2), within a few hours of release... these are some of the benefits of having an experienced dev working on your device...

You have to update then do the steps, because you'll lose root on updating
