At first, I jailbreaked my iPod touch. I then un-installed it so I could download the new apple applications. After that, the iPod touch would work, but music and videos (when clicked on from the home screen) just returned to the home screen. I then used the Pwnage tool for mac and tried to upload a clean 1.1.4 version to the iPod. It started out installing okay, but I think half-way through the process, the iPod just turned off. (It was at the screen where it looked like terminal and started to say something like "Auto Pwn"). When I try to turn it back on, nothing shows up and it won't turn on or go into recovery mode. I've tried it on multiple computers and it still won't turn on. What can I do?
