ATV 2 Stuck in DFU mode, won't restore or jailbreak

Connected it to my computer.
Opened Seas0npass & it would just sit at downloading the ipsw and then say to check my connection even though everything was connected and my firewall was off.

Tried restoring it through itunes but it errors out and won’t restore.

What should I do?

Update to the latest iOS from iTunes while in DFU or not. Then enter DFU and restore using the 5.3 ipsw.

Run Seas0nPass as Administrator to ensure that the application has permissions to read and write new files.
