hey , My ipod was jailbreaked before with greenpoison , Then i was stuck in DFU (black screen loop) ! Then i downgraded to ios 4.1 ! Then "Just boot tethered " it ! The ipod was turned on !!! for a moment anyway . Then the screen went off ! And now , i can play the songs through the voice recognition (holding the home button) ... i tried holding power and home button for 10 secs but it took me to that stupid dfu mode ! Then i had to boot tether again ! No screen though ! Can anyone help me ? please ? Its really frustrating!
