I have a jailbroken ipod touch 2g and stupidly didnt restore it before i tried to update it to 18.104.22.168 and not it just shows a picture of a cable with an arrow pointing to itunes. Everytime i plug in my ipod it just says found new hardware usb device and doesnt recognise my ipod. When i try to update this new it just says cannot continue hardware. I tried putting it into DFU mode and still nothing. What do I do?
