Does anyone have a fix for this? My iphone is a 4, and it has iOS 5.0 jailbroken with redsn0w. Its tethered right now, and i let it die last night. I charged it all night and planned to boot it this morning with redsn0w again but its not reacting to anything. I held the "hold" and "home" buttons for different increments of time, 10, 15, 20 seconds. i tried putting it into DFU mode and no luck, its just a brick. EDIT: the backlight is on, i just realized this. Its technically "on" (?whatever the eff that means) but nothing else.
