Ok, so i jailbroke my iPod Touch 2G about a week ago, then i noticed it lagging a lot and since my computer was being repaired i couldnt restore it so i went into the settings where you can erase all content and data (this is what my friend did, although he said it can take a long time) so i left it on overnight, when i got up i found the ipod on the apple logo, it then turned off, and restarted, it got to the apple logo and did the same again, it now keeps repeating it, i plug it in and neither the pc or iTunes recognizes it, and i cant put it into restore or dfu mode so i cant do anything on it.
