Here is a tutorial to Root your Sony Xperia S with locked bootloaders.

Disclaimer: By following this tutorial, you agree that the Rooting process will be undertaken at your own risk. No member of this site will be responsible for any bricked phones!


  • You must be running the latest ICS Android v4.0 – 6.1.A.0.452 firmware. To check if you are running this version go to Settings > > About Phone
  • Download the Superuser flashable zip file from here.
  • Download Nozomi Recovery from here.
  • Download the kernel to be flashed from here.
  • You also need to install the Android SDK onto your PC. If you haven’t already done that, you may download it and install it.
  • Make sure USB Debugging is enabled from Settings > > Developer Options > > USB Debugging.

We recommend taking a backup with Nandroid or Titanium backup; so that you can always recover all your data back, in case something goes wrong!

Step-by-Step Procedure:

Step 1: Navigate to C:/android-sdks/platform-tools/ and place the recovery file here.

Step 2: Hold Shift key + Right Click the mouse and Select open a new command prompt here.

Step 3: Connect your phone to the PC and type the following in the command window that you opened in the earlier step: adb reboot-bootloader This will reboot your phone in fastboot mode and turn the LED blue.

Command Prompt

Step 4: Now in the command prompt window type: fastboot flash boot recovery-nozomi.img

Command Prompt

Step 5: Once this is done, Unplug the device and Reboot the device normally. Again connect the mobile to the PC and place the Supersuer file in the root of SDcard.

Step 6: Type in the command window: abd reboot recovery Now your phone will enter Recovery mode. In the recovery mode, Select flash zip from SDcard and flash the superuser zip file..

Step 7: Reboot into system via the recovery.

Step 8: Extract the kernel.rar file and place the kernel.sin file in C:/android-sdks/platform-tools/

Step 9: Repeat step 3 to enter fastboot and type in the command prompt: fastboot flash boot kernel.sin

    I m running 6.1.A.2.45 . will it work for me?

      Oh indeed it will. However there is a slight problem(which is quite insignificant). Since the tutorial is for a older 6.1.A.0.452 the kernel is also of the same built. However this wont affect your phone much.
