To just boot tethered in Redsn0w after installing an app that requires a reboot, or after the battery dies, how do you get the phone off to enter DFU mode? The battery will be dead, or the phone will be stuck at the apple logo - in either case, you can't simply hold down the power button & swipe to turn off. Is a hard reset required? Oddly enough, I can't find a thread/YouTube video with the specifics of this process outlined... Thanks!
