Are you sure that you used the very latest SeasonPass to do the jailbreak released in the last few days? That is the symptom I would expect from the earlier tethered jailbreak.
100% sure. I got so many errors trying to jaibreak my ATV2. error 11, 1601-1604 in itunes. This last time i got
“This device isn´t eligible for the requested build” both with seasonpass and just itunes. I ran out of option and i just plugged it in to my TV one last time and it worked?!?! Don´t know what i did but it works? So strange.
The weirdest thing is that Itunes could not restore original firmware. Should i be worried that something is seriously wrong with my ATV?
