We were previously talking about how HTC ships their devices with locked bootloader. Sony is on the same boat. In this post, we are going to discuss how to unlock the bootloader on Sony Xperia phones. The process is fairly simple but it will void your warranty, and not to forget you will also lose your TA partition which is responsible for making proprietary features such as X-reality and X-loud work. But if you are few of the people who consider them as gimmicks, you can probably overlook that loss. Other than that, you won’t be able receive OTA. But the advantages include full control over system, the ability to flash custom ROMs and kernels without having to worry about any restrictions.
Unlocking bootloader on Sony is a walk in the park, all you need is some knowledge. So without anymore delay, let’s take a look at how to unlock the bootloader on Sony Xperia devices.
Step 1: First of all, go here and check whether your phone is supported for the bootloader unlocking or not, if not; there’s no use as it won’t work. Once you’re done checking, download the Fastboot drivers from here.
Step 2: Open the dialer on your phone and type *#*#7378423#*#*, you’ll be taken to a service menu, once there, go to Service Info > Configuration > Rooting Status and check if it says that the bootloader can be unlocked.
Step 3: Extract the file named ‘downloadinf.zip’ that you downloaded in the first step and copy the extracted contents to c:\android-sdk\extras\google\usb_driver; if it asks you to overwrite something, click yes.
Step 4: Open the dialer and dial #06#. You will be given the IMEI number of your phone, write it down CORRECTLY on a piece of paper; once you’re done, visit the link.
Step 5: Once the page opens, click on ‘Yes, I’m sure’.
Step 6: The next step will present you with Sony’s legal terms, agree with them and then click on ‘I accept’.
Step 7: On the next page, you will be asked to enter your name, your email address and your phone’s IMEI. Enter the credentials and press ‘Submit’.
Step 8: You’ll be given an unlock code, write it down somewhere.
Step 9: Turn off your phone and plug it in using the micro USB cable. Make sure you’re holding the volume up key while you’re plugging the micro USB cable.
Step 10: Go to c:\android-sdk\extras\google\usb_driver and install the drivers.
Step 11: Now open the command prompt and type the following command, make sure the entire command is typed all at once:
cd C:\android-sdk\platform-tools; fastboot.exe -i 0x0fce getvar version; fastboot.exe -i 0x0fce oem unlock 0xKEY (replace key with the code obtained before).
That is it, your bootloader is now unlocked and you’re good to go. Make sure to remove the USB cable and reboot your device.
