I am having trouble downgrading from 6.15.00. Am using windows 7, redsnow 0.9.14b2. 3G iOS 4.2.1. Run redsnow downgrade iPad bb. Goes through fairly quick. Doesn't take as long as sticky says it should. When through the phone is unusable. Gives message iPhone need restore through iTunes. It can be restored with no problem to stock 4.2.1 which tells me the baseband was downgraded. Am I missing something. Any help would be appreciated.
