Looking for stock rom

Looking for stock rom

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:


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.

Re: Looking for stock rom



you have to relock the bootloader if you want to use XC, also, download Xperifirm or flashtool
