I got this ipod touch that was stuck on the usb connection screen from a friend. I tried putting it into dfu and i guess it worked. Then i unplugged it since i didnt think it worked and now it wont turn on or do anything. Ive tried holding the home and power button and ive tried a lot of software and it cant recognize it. On the device manager it comes up as usb dfu device. Is there any way to restore it back to normal?
