I've had my Apple TV (ATV2) jailbroken with Seas0nPass for awhile now. Last night, I ssh'd into it and updated Plex and XBMC. After doing so I can no longer get it to boot back up. I tried restoring it with Seas0nPass ipsw, but I guess Apple is not signing 4.4.4 any longer. I can still SSH into it. Can anyone give me a few suggestions on what I should do?
