1: You MAY void your warranty!
2: Unlocking bootloader will result in data loss! Be sure to backup! (SD-Card won't be affected)
So I've never seen any Tutorial on this for Xperia V and decided to make one!
Step 2: Extract the file you downloaded above on your PC. You’ll get the following three files:
1: This will open a web page in your default browser. Scroll to the bottom of the Instructions on the page and you’ll see a link like “Continue”, click on it.
2: In the pop-up window click “Yes, I’m sure” and then in the next window click on both the checkboxes, and then click “I accept”.
Remember! IMEI can be found by entering *#06# in the phone application!
Step 6: Extract everything in step 2 into a folder
Step 7: Put your phone into fastboot mode
Turn your phone off. Press and hold Volume Up button while plugging your phone into your PC. A blue LED will come on
1: Search 'Device Manager' in the start menu
2: Right click your device (Should be S1Boot Fastboot OR Android Phone)
3: Click 'Update Driver'
4: Locate the driver folder (Remember to extract 'driver.zip')
5: It will automatically install
Step 10: In the same folder as the extracted content of fastboot_with_Android_USB_file.zip, open command promt
Hold Shift while right-clicking in the folder and select 'Open Command Promt'
1: Type in fastboot.exe -i 0x0fce getvar version
2: It should return a value like “0.5”. This ensures that your device is correctly connected
3: Now type in fastboot.exe -i 0x0fce oem unlock 0xKEY
Important! Remember the code you recieved? Replace KEY with that
That's it from me! Please leave a comment if i have done anything wrong. (First Tutorial post by the way )
