You will now have a locked stock xperia z
Extra info by Flashtool developer:
A litte explanation :about relocking / unlocking :
When relocking the device, I save the unlock code into custom\DEVICESERIAL\unlock.txt
If ever you relocked using another method than BLU from FT (with a custom ftf for example), then you must create this file by hand to be able to unlock the device again.
This file must contain the unlock code. One line only, no carriage return.
