Hi I have an iPod 1G which i bought around a year and half back. recently i upgraded the firmware to 3.1.3. Now i used redsn0w 0.9.4 to jailbreak it. As adviced by many of them i pointed it to 3.1.2 ipsw and put the ipod into DFU mode. But then it freezes at 'waiting for rebbot' and nothing happenes. Neither the ipod flashes nor the redsn0w window. i tried uplugging and replugging the ipod as adviced by some people. but nothing goes. Any idea what could be the problem?
