I just updated my aTV to 2.4 firmware and have attempted to install the 3.6.1 software from the thumbdrive using the usual procedure. I’m been doing this for over a year so I am no n00b. It doesn’t seem to even see the thumbdrive now and will only boot from the internal harddrive. I’ve tried it now with two separate Memorex thumbs, my original 256mb and a newer 512mb version. I’m not sure what to do next short of doing a complete factory reset.
The USB port worked fine as of yesterday with the 3.5.6 aTV software under the 2.3 firmware, as I had a external hard drive serving media.
Any ideas as what might have happened?
