But be advised that everything written here are only tutorials to unlock bootloader your Xperia Smartphone, and methods may differ on other models. I’m not held responsible for any loss or damage of your Xperia Smartphones. Make sure you have an Internet Connection to complete the whole process.)

RULE OF THUMB: READ AND FOLLOW THE INSTRUCTIONS CAREFULLY

WHAT YOU NEED TO PREPARE FOR UNLOCKING BOOTLOADER ON XPERIA:

1.) First, confirm the device if it’s possible to unlock boot loader by checking the service menu. In your device, open the dialer and enter *#*#7378423#*#* to access the service menu.

From you device, 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.

2.) You need a valid email address. (You need this because they will send to you the unlock boot loader key, for example: 4HB216F744C5CDE6)

3.) Know your device’s IMEI or MEID or IDID number (to do that open your dialer, and dial *#06#). You will need the first 14 digits of your device’s IMEI or MEID or IDID number.

Example: After you dial the *#06#, it will show the 15 digits of your device’s IMEI or MEID or IDID number, like this: 123456789012345. From there, you only need the first 14 digits, like this: 12345678901234.

4.) For unlocking your Xperia Smartphones, make sure you have JAVA SE Development Kit. (see the sample screenshot below).
