Phone stuck after firmware flash

Hi everyone.
I try to root my Z3 with Locked Bootloader with this guide
http://forum.xda-developers.com/z3/g...stall-t3017056

The first thing that do is to flash firmware version like written in the guide by using "Flashtool".

After the firmware flashing processes the phone is turn on and stuck on log screen (the blue animation).
How can i fix it?
thanks
