[Q] Need help to flash LT30a with Bell Mobility
I have a Sony Xperia T LT30a running Jelly Bean 4.1.2 (9.1.A.0.489) with Bell Mobility. This is the latest update available with Bell. The bootloader is locked and the phone is not rooted.
I'm having all kind of problem that seems to be common with .489 (low battery life, Walkman won't play next song when screen is on sleep, internal speaker won't work after unplugging jack, etc).
I would like to know if it's possible for me to update to a stock odexed 9.1.A.1.141 rom with a locked bootloader and without rooting the device. I want to keep everything as stock as possible but with the 141 update. I want to keep LTE Support, WiFi and USB Tethering support, etc
