Steps I took:
I reset the Apple TV to factory settings and did all the updates to get it to Software Version 2.3.1
Created the flash drive install I tried it on 3 different flash drives. I followed all the instructions correctly. I got the “aTV Flash has been successfully installed”
Unplugged the Apple TV, inserted the Flash Drive and Plugged the Apple TV back. The Apple logo flashed a couple of times and then restarted to the normal Apple menu. So aTV did not get installed.
I also formatted the flash drive to “Mac OS Extended (Journaled)” and that didn’t work so I also tried “Mac OS Extended”
I’ve tried a Kingston 512MB Flash Drive, and 2 no name drives, 1 4GB the other 8GB.
What am I doing wrong?
