Do you have a radio loaded yet? PG05IMG is how you load a radio. New Radio Rip 2.11.605.19 PG05IMG.zip - xda-developers is the most recent MR2 radio for thunderbolt. If you have a different phone, find the right radio or radios, dl to your sd card and boot in recovery and flash them one at a time. I am a noob and im not sure where you are in the process of flashing so im not sure where you are having trouble. Did you already flash the rom?
