flashinf branded ftf to another Z1

[orzech.miron]

Hi guys,
I have locked bootloader on my Z1 and flashed sometime ago rooted version. I also made .ftf of my firmware because I have branded software.
Now, my father updated his Z1 to kitkat (officialy) and he has a lot of problems with it. Can i flash .ftf from my Z1 to my fathers one and everything will be ok? Warranty will be void or not?
