iPod will show sad folder then it will show the sad iPod?
I’m flash modding my iPod and when I turn it on the sad floder will appear (as expected) and it will try to connect to my computer, but once it does, it will turn off and then on again (disconnecting) and the sad iPod shows up until I unplug and then plug the battery back in. After that it just does everything over again.

ANSWERS:

Try restoring the iPod on iTunes.
