Unlock Bootloader Xperia S steps by steps :

Quick tutorial for unlocking & relocking the bootloader of the Xperia S.

this is the official way to unlock bootloader


This procedure will wipe the /data partition of your phone, so you will loose all ur stored data, settings. SDCARD will NOT BE WIPED!!!

DRM keys WILL be lost forever

Most of this is taken from lollylost100's his tutorial from ARC thread (all credits for that concise tutorial go to him, i have elaborated on a few things and added device specific changes)

btw i dont have this device, most of this testing was done on user darkpisces's phone so thanks a lot to him for helping me out!!!

[ before we begin unlocking bootloader ]

  • get the IMEI code for ur device: type *#06# in phone dialer to find it out, note only the digits (no dashes)
  • download the fastboot package with usb drivers
  • make sure u have a windows PC with USB cable to connect the phone
  • power down ur phone and keeping the Volume Up button pressed connect the USB cable to PC this will trigger FASTBOOT mode and windows will start driver installation, extract the above package and point the driver install to that location (usb_driver) folder
  • once drivers are installed just disconnect cable and power on device

[ how to unlock ] (official way)
  1. Go to: and read everything!
  2. At the bottom click 'Start Unlocking the Bootloader'
    First, you should confirm that it is possible to unlock the boot loader of your phone by checking the service menu. In your phone, open the dialler and enter *#*#7378423#*#* to access the service menu.

    In your phone, tap Service info > Configuration > Rooting Status. If Bootloader unlock allowed says Yes, then you can continue with the next step. If it says No, or if the status is missing, your device cannot be unlocked.
  3. after u have verified that u can unlock bootloader, scroll to the bottom of the page and click "Continue"
  4. you will get "are u sure prompt" accept it by clicking "yes i am sure" (i assume that u have read an understood it)
  5. then accept the "legal terms"
  6. finally u will get a "Create Unlock request" page, enter your IMEI (sometimes the last digit needs to be removed for this to work), name and email address
  7. You should now receive your unique unlock key, its displayed on screen, SAVE THIS KEY SAFELY
  8. Extract fastboot_with_Android_USB_file.rar and open fastboot folder
  9. Hold SHIFT and right click on the background of the folder
  10. Select 'Open command window here'
  11. Connect your phone in fastboot mode (turn phone off, hold Volume UP button and plug in USB Cable) [make sure drivers are installed as explained above)
  12. In the cmd windows type in fastboot.exe -i 0x0fce getvar version
  13. If a value is returned (it will return 0.5), it means the phone is correctly connected
  14. Type in fastboot.exe -i 0x0fce oem unlock 0xKEY and replace KEY with the key which u received earlier.
  15. You're device should now be bootloader unlocked

If this tutorial is too much for you then itskapil wrote a step-by-step guide (and recorded a video also):
(the above videos and some steps are for Xperia 2011 devices, but most the steps are same for Xperia S)

                                            Relocking Bootloader
this Relock FTF is based on the package posted by Blagus in his ARC thread (all credits for this go to him, i have only added the correct loader.sin for this device)

before we begin relocking the bootloader make sure that u have flashtool download & installed

u can get the latest version of FlashTool from:

download link is under "Installation" tab

if u have not use FlashTool before read this thread:

download this FTF: Xperia-S_Relock_bootloader.ftf
flash this FTF via FlashTool

when it says enter flashmode, power down device and keeping VOLUME DOWN button pressed connect usb cable to phone, the device will now enter flashmode (green LED)

after this file is flashed reboot phone

bootloader will now be relocked!!!

incase device doenst boot DO NOT PANIC... u can flash stock firmware FTF anytime to get back to stock ROM... i will post link to working FTF once its available...

P.S.: there is no official way to relock bootloader
