Following the online instructions, for tethered JB with latest firmware. Then did a tethered boot, then installed aTV Flash Black 1.1.1
All working, install everything via maintenance but need to move aTV to media room, not next to my Mac. So put it to sleep, and replug it in to my TV.
That is when I get the quick flashing light on the front of the Apple TV, and the 'plug into ITunes" symbol.
Have gone through the same process twice now, with same results. Thoughts?
