It took me forever trying to tinker around with my broken power button to finally be able to use redsn0w and when The phone rebooted a blank cydia was there and empty. I've tried all of the YouTube videos and searched various forums but none of them seem to work. I ve tried to put my phone back in dfu mode and can't so I cant rejailbreak it through redsn0w. Does anyone have any suggestions?
