If you're getting a black screen and it says the device has failed, there IS a way to fix it. I've been trying for 5 hours, and I realized that I simply have my timing wrong resetting it to DFU mode. So do this: 1) Open iTunes 2) Plug in iPod, let it say the device is failed 3) Hold down Power and Home for TEN seconds, and DON'T let the "Device Failed" thing pop up again (count to ten!!!!!) 4) Let go of Power but keep holding onto Home....... and voila! It will be recognized! Hope this clears things up: just remember, all you need to do is get the timing correct.
