I installed Rock box on my i-pod nano yesterday. It's running but if I connect it to my pc nothing happens. Windows detects it as removable disc but I can't access it (in explorer it says insert removable disc). I cannot update my ipod anymore as it doesn't detect it properly anymore. I tried to unistall Rockbox but it sais that configuration is invalid even if I set it properly . Basicly my ipod wont go in the update mode whgen it's connected to pc but stays on. I cannot reistall using original apple sofware either.
