Hi I have a big problem: After I tried to jailbreak my iPod it won't turn on anymore. I even can't get into the DFU mode. Everything worked until the rebooting message appeared on the screen of the iPod, then the screen went black and when I tried to turn it on after a few minutes, nothing happened (also tried holding home + sleep buttons). Then I tired to restore the firmware, so i tried to get into DFU mode, and nothing happened here, too. The iPod isn't recognized by the PC anymore. Is there any solution?
