I installed the official AppleTV 3.0 update and it rebooted to a blank screen. I then installed the aTVFlash 4.0 update and got the same results.
It then hit me that I use an external USB drive to store my iTunes data and that I failed to switch it back to the internal drive before I ran the updates. I’m assuming that this is the problem.
What am I left to do? A total wipe and reinstall? If so, then how?
