I tried to jailbreak a 1.1.4 iPod Touch. I was happy with it but I wanted to remove it. I used ZiPhone to jailbreak it and then downgrade it. Problem is I run Vista and a UAC message popped up stopping the ZiPhone undo-jailbreak process midway. Now I am left with a black screen with some white text and ZiPhone cant detect the touch and furthermore the power button is not currently working. How can I get my touch working again?
