I have a friend with an AT&T Moto X. He is selling it and offered me a good deal on it. It is already unlocked (I know I may need to unlock it again if I change roms and such but I assume his code may carry over and I don't mind buying an unlock code if needed). I am very interested in the phone but would prefer to have the official stock T-Mobile rom on the phone. I can install a custom bootloader if necessary, but I cannot find an official T-Mobile rom for the phone. Does anyone know where I could find the official stock T-Mobile rom or know how I can switch it to the T-Mobile rom from the AT&T rom? Thanks
