So I see people posting firmware ending in B07 and B04 for the T-mobile variant, the Metro version came with B08, but I just randomly decided to check for a software update on a whim and found b12 is available for my phone, it's a 368MB download so not a tiny update. Does anyone know anything about it? Afraid to flash without knowing what to expect, but I'm sick of the phone softbooting 1-2 times a week and charging to 80-85% overnight then stopping sometimes, so if there's anything in this update that might fix that then I'm curious to flash it and see what I get.
