Apple TV (3rd gen) factory reset
After Apple had released the latest update for the Apple TV I turned mine on and went through the update process. It kept saying that there was an error and before long the "Status Light" started flashing quickly. So I plugged it into my MacBook Pro and went through the process of restoring it (downloading the software then installing it onto the Apple TV) but I kept getting Error 21. After looking it up and making sure I had the latest version of all the software and that there was no security software activated and many resets I tried resetting it via a Windows computer and got the same errors.
Anyone get any ideas?
