Did you get stuck jailbreaking or installing summerboard?
Easy to get in trouble installing summerboard if you forget to correct permissions. If you can still SSH in, try setting permissions to 755! Otherwise, you may be stuck- restore and try one of the automated installers.
Plug it into another computer and then restore it. If that works and you plug it into the original computer and it still doesn't reconize it, hold down the hold and home button for a bit and then it'll go in restore mode then restore it again. This is what I had to do to get it working again.
To restore your iPod:
Hold down the sleep and hold buttons until the iPod flashes, then LET GO of the sleep button but, KEEP HOLDING the home button until the iTunes sync icon displays. Then plug it into your computer and it will ask you if you want to restore the iPod. It works... do some searching.
I'll try that....But I think i've tried every variant of the button hold...I have blisters on my fingers from holding those buttons.
I called apple...and they didn't tell me that.....to be honest, the lady I talked to, did'nt seem to know much about the ipod at all.
thanks
