i'm in trouble: I found an old 4th gen ipod (40 gb), I've connected it up my computer and it worked, so I installed rockbox and I started listen to music.
After a while I putted inside other music but I was no more able to play the music (I had the chance to see the songs but they didn't play, and maybe also the folder's icons changed), so with the rockbox utility I deleted rockbox, but the utility was inable to erase the bootloader too.
Now I can't start the ipod because of a rockbox bootloader error message, and when I try to connect the ipod to the computer (both in "normal" or disk mode, I can't format the unit because I can't access the device!! Furthermore, when the ipod is connected to the computer, the laptop seems to be "blocked", and when I disconnect the ipod, for example, itunes opens itself saying "your ipod is corrupted, you have to restore it, click the restore button" (but of course it is too late because at that moment the ipod is no more connecter to the laptop!)
It was so hard to describe my situation but hope someone can helps me!!
