I also first got "update unsuccessful", now trying again and getting "The AppleTV update could not be downloaded at this time".

Did Apple realize there's a bug at the last minute and pull the release? Seems like it.
 
Mine crapped out the first time,,,,now the download timer is moving the wrong way, up to 45 minutes...on eth
 
OK, I've had 3 failures now. I'm going to back off and try again later. I have my hands full with OSX and iPad right now.

My Apple TV is telling me to plug into iTunes. Too bad I don't have a micro USB cord...what is going on? Is my Apple TV bricked??😡
