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.
