Hello, I have put my iPhone in DFU mode, and it is not turning back on. I tried the holding buttons plenty of times, and still nothing. I tried different techniques, and nothing happened. I put it in DFU mode, and tried to update the software, BUT, it didn't update, and I tried so many times with so many programs, but it doesn't work. I decided, screw it, so I tried turning it back on. It is not coming on or getting out of DFU mode. Please help.
