And to flash my phone back to fro yo, I need to get on a computer and what do I do? Just google the sbf file and I'll find it, then connect my phone to my comp and do something? Sorry for all the questions im just curious about trying gb but I don't want to screw myself over in the process for not bring able to get back to here if I wanted to...
