Well, I upgraded my iPod Toucg 2g to 3.0 firmware a couple weeks ago and then I jailbroke it using, i believe redsn0w. I decided to respring it since this app wouldn't show up and I did and once I did, it did not turn on. All it would do is show the apple boot logo and that's it. I tried putting it into DFU Mode but when i tried, iTunes would say there is an error. A few minutes later, I tried it, and it won't even show the apple logo anymore. Also, it won't appear on my computer as an unknown device or apple device. I NEED HELP!
