You should re lock your bootloader bro for this to work
I sld suggest u Xperia Flashtool it has a BLU option that automatically locks and unlocks bootloader
u just have to download this and click on the BLU button on the Left Top then just swith off your phone keep the Vol Down key pressed and attach the phone to computer via USB and it will ask u model number choose appropriate and then it wld ask you to Lock bootloader and you are done
