I recently tried to jailbreak my iTouch 2g using blackra1n. I am running firmware 3.1.2. It was successful. I then unplugged my iTouch from the computer, played with it for a little and then I rebooted it. I had to reboot it because an app required me to. I then tried to turn it back on and it doesn't. The screen only displays the Apple logo for about 7 seconds and then goes black. When I plug it in, Windows says "USB Device Not Recognized." Can anyone help me? I tried using DFU mode, but the iTouch doesn't stay on long enough. If you could provide links or a walkthrough, that would be great. P.S. - If this cannot be fixed (which I hope it can), will I be able to take to an Apple Store to get it fixed. My one year warranty is not up yet. If the iTouch is fixed there, will they be able to tell I jailbroke it?
