I'm now stuck on 5.0.2 after attempting to upgrade from 5.1 to 5.1.1.
My Apple TV (3rd gen.) was running 5.0. I tried several times to update to 5.1.1 from within the Apple TV UI. It failed every time. (Network connection was Ethernet.) The final attempt hung and bricked the unit.
I attempted to restore to 5.1.1 within iTunes 11. Every time, I got error 14 ("An unknown error occurred"). Thinking perhaps I had a charge-only micro-USB cable, I ordered a new micro-USB cable and waited for it to arrive. The same thing happened when I attempted the restore in iTunes with the new cable.
I next tried to restore to 5.1 within iTunes. The progress bar got halfway and then hung. This happens every time.
Then I tried to revert to 5.0.2 within iTunes. This restore succeeded.
I then tried several methods to update from 5.0.2 to 5.1.1 -- Ethernet, wireless, Restart then Restore, Reset > Restore. All failed with "An error occurred."
Again I tried to restore to 5.1.1 and 5.1 within iTunes. It failed with error 14 (5.1.1) and incomplete restore (5.1).
I then reverted to 5.0.2, and that restore again succeeded.
I noticed that the 5.0.2 .ipsw is about 80MB smaller than the 5.1.x files. Perhaps this has something to do with the restore failures on my unit.
The Apple Store replaced my Apple TV. The Genius suspected the flash storage was failing. When I got the replacement unit home, I tried to update it via iTunes on Mac. I ran into the same issue I had with the original unit. I could update to neither 5.1 (hung midway) nor 5.1.1 (appeared to complete but failed). However, I could always restore to 5.0.2 without issue.
I first used the firmware .ipsw downloaded directly from Apple via Firefox. So I decided to try to have iTunes download the firmware. (I had to revert to iTunes 10 to get iTunes to download it due to a bug in iTunes 11.) The download completed, but iTunes reported that it was corrupted. I did this twice, and it was reported as corrupted both times.
Then I decided to download the 5.1.1 .ipsw with Safari. Lo and behold, iTunes successfully restored the Apple TV with the Safari-downloaded firmware.
The file sizes from all three download methods (Firefox, iTunes, Safari) were identical, but I did not diff them to validate that they were truly identical.
I suspect there was absolutely nothing wrong with my original Apple TV.
Now I have the 5.1.x issue of Ethernet not working with Hulu Plus, Photo Stream, etc. It is astounding that Apple put out 5.1.1 without the Ethernet fix.
