hi guys, today i got notified that there is a new update for my c6602 which is 10.5.a.0.233)
tried to update it via sony pc companion but i got an error because of using modified software (bootloader unlocked)
i tried relocking it via flashtool BLU button but the phone wouldn't boot so i had to unlock it again
is there a working method for relocking it?
thanks

it worked by using the flash tool to relock the bootloader using the BLU button (but after this the device won't boot)
then i flashed the new FTF file, i got the new firmware and the bootloader locked

The bootloader is not relocked when you flash stock FTF.
You will loose custom recovery and root.
Flash recovery and root again.
