[poblacion86]

I flashed my htc touch pro 2 to mighty and want to go back to sprints stock rom. I d/l the two herman shipped roms and tried both of them and it did not work, it gets stuck at 1% then it gets error 244: invalid model ID. I dont know what that means. If theres anyone out there that can help me flash my pro 2 back to sprints rom, please help me do it step by step, thank you so much.
