My Niece has a 4th gen iPod that she could get to do nothing so she ask me to look at it. Well it shows to plug into iTunes. When I plug it into the computer the computer doesn't recognize it at all.. It does charge but there is no "bong" sound indicating a device has been detected so obviously iTunes does nothing for it. Also the device will not shut off or go into DFU mode. It has two screens one is a quick flash of the apple logo followed by the plug into iTunes screen. Does anyone have advice for this device??
