Here's the guide on how to unlock the bootloader !
This passage will void your warranty so do this only if you know what are you doing. By unlocking bootloader you can flash more custom ROMS then on unlock bootloaders and you can also flash custom kernels !
You will also lose your apps !
Start !
1| On your XU go to dialer and write
Code:
*#06#
and copy your IMEI on a sheet
2| DOWNLOAD this file. Inside there are fastboot and drivers.
3| Extract "fastboot" folder in a directory {es : desktop}
4| Extract "drivers" folder and install drivers. WARNING : If you have installed drivers before,do not install them again
5| Go to http://unlockbootloader.sonymobile.com/instructions and click "Continue"
6| Now select "Yes,I'm sure" and "I accept"
7| Now insert name,email and IMEI without the last number
8| Now check your e-mail box, you should find an email from sony .You will receive an unlock code that you will copy on a sheet
9| Connect XU in fastboot mode {volume down and usb cable}
10| Open "fastboot" folder and press "S-H-I-F-T" + right click > select "Open Command Prompt here"
11| Type this :
Code:
fastboot.exe -i 0x0fce getvar version
12| If drivers are succesfully installed,you should get this answer :
Code:
05
13| Ok,now type this :
Code:
fastboot.exe -i 0x0fce oem unlock 0xKEY
IMPORTANT : REPLACE "KEY" WITH THE UNLOCK CODE THAT YOU RECEIVED VIA E-MAIL !
14| When finished,device should automatically reboot
15| You have unlock bootloader ....Haters gonn HATE:laugh:​
