A while back i unlocked the bootloader, rooted and installed a custom rom. But now i want to go back to the stock rom but i can't seem to find an official Xperia z1 rom. I have installed a stock rom (UK Region) with no root amd i have re-locked the bootloade, but it doesnt allow updates through ota or pc companion. I think it is a customized version of the firmware. If anyone has found a soloution to this problem please!?
