So I have the Brasilian variant of the Xperia Z1 ( C6943) its out of warranty already, so I wanted to unlock the bootloader, install a recovery and probably CM11. Te problem is, I'm allowed to flash the .534 rom of the C6903 over the stock .757 that it is running? I would not brick? And to install the recovery and unlock bootloader I just do the same as to the locked bootloader?
