Hi there, my first message on here. I am a total noob really, just had to root my phone to unlock it from TMobile, but it is still "branded" - loading with a TMobile logo on boot and a nice trademark little tune to go with it. I basically want to debrand it the most reliable way possible, as long as it does not affect my device in any other way? Please could someone either explain or direct me to a "noob step-by-step" guide.... Thanks in advance.
