Carrier: sprint
Touch pro 2 unlocked with mighty rom

A friend unlocked this unit and put mighty rom on it for me. I spent many hours searching for a thread with with the same symtons as this unit without much success. Iv read up on how to do the unlock and rom loads....but have never performed the procedures(friend did it) Phone worked great for long time. the phone now is completely frozen after the load finishes. i need to bring it in to get a new one replaced. cant have them seeing that 'mighty rom' on the load screen.i have done a hard reset.. the phone appears to be unable to enter the bootloader. i press the dwn vol/power and it enters the process...white screen blinks for a split then back to the rainbow screen with no options. im to the point where im fixin to just spend the 100$ deduct and get a another. would like it free though. cant link it to the pc because its froze....any help would be much appreciated

Thanks
