Flash Stock Sony Firmware on to carrier locked phone

Hey guys,

I have one or two questions I cant seem to find a definitive answer for.

I currently have a Z1 locked to my local O2 network. They still haven't release any updates past 4.2.2.

I was wondering would it be possible to flash a Sony Stock Factory Image so that future OTA updates would come from Sony and not through my carrier?

I was looking at this ROM here. So Root the phone, flash the ROM and then remove root.

Some might say why not root, unlock etc. but the to be honest I have done my fair share of trying different ROM's on different phones, throughout the years and I just love how stable the phone is and how good the battery life is that I just don't want to mess around with it too much.

Dave

You already messing around. That link which you posted is a method to root your phone and if you do not want to root it then is not the right thread. To update your phone to latest FW you have to flash the Unbranded Firmware .136 for your model from HERE

Use flashtool v0.9.13 to do that, wipe everything and you are done. This is for Locked Bootloader and you will also get next Updates when they comes.

Yes, it's simple because you just want the latest Firmware only, No Root, No Unlocked Bootlader.

One last question, if I flash the latest UK version which is .290 will I receive OTA or PC Companion updates as soon as .136 is out for the UK version?
