Hello all,

I'm trying to help a friend jailbreak his phone. He is in Texas and I'm in Pennsylvania. He has an iPhone4 running 5.0.1 and is attempting to use redsn0w 0.9.10b3 to untethered JB. He can get into DFU mode(verified in itunes) but every time he runs redsn0w and starts the DFU mode process, he gets booted out. He has tried to restore and still the same thing happens and i just don't know what else to suggest for him to try. Any thought on this matter would be greatly appreciated. TIA
