You see, even though there is an official way made available by Sony for unchaining the internal system of your Xperia device, the actual procedure is quite hard to complete there being a lot of stuffs to take care of. That’s why most of the users are still having troubles (and often they are ending up in bricking their smartphones) in unlocking the bootloader, but the unpleasant situations can be avoided if a dedicated and suitable step by step guide, just like the present one, is being followed.

But, first let’s talk a little bit about the general aspects related to the bootloader term. Well, the bootloader is a small program that runs each time you power up your Sony Xperia device. The bootloader is located in the ROM memory and basically when it runs the OS and its programs are loaded into the RAM memory. So, you can associate your phone’s bootloader with the program that runs each time you power up your computer or notebook. Now, when you first buy a device it will be delivered with a locked bootloader, so unlocking it it’s your job.


Before proceed do this thing:-

  • Backup the data which is being saved on your handset, because you can lose all of your personal info and saves.
  • Then, a Windows running computer with internet connection enabled must be near you.
  • Also, the Sony Xperia smartphone and its USB cable should be there.
  • On the computer first deactivate the security programs like antivirus and Firewall protection.
  • Then, get and install the Android SDK on your computer; also install the fastboot drivers from here.
  • If you notice that your handset has less than 60% power left, before heading to the next steps, charge its battery; else the phone might get turned off in the middle of the unlocking procedure.
  • Enable the USB debugging option on your device.
  • Take note as if you unlock the bootloader you will no longer receive OTA updates.
  • Apply this method only for the Sony Xperia devices.
