Can you try restarting the AppleTV and re-running the aTV Flash (black) installer?

 

Just happened that to me right now. I restarted, but same thing. For bedroom ATV2 with firmware 4.4.4 I could update successfully but for the other ATV2 (firmware 5.0.1) I receive this error. Any ideas why James ?
