I recently bought a Z3 compact D5833 that had cyanogenmod 12 (rest in peace) and I want to restore the stock rom to get some updates. I managed to flash a few different ones I found on xda with no luck. They would always crash after the boot animation. The problem is that I am not sure which stock rom region I should be using because I have no idea where this phone originally came from and the person I bought it from is not being helpful. I ran the Xperia Companion (XC) and it says Boot loader unlocked Below is a link to a jpg of the side tag pull out thing with more info: https://www.dropbox.com/s/a4n80dnl0akhyvd/xperia%20z3c.jpg?dl=0 I think I am flashing the roms correctly with a method I found on xda but I just need the stock rom or a way to lock the bootloader for the Xperia Companion application.
