I have tried unsuccessfully to upgrade my Apple TV software from an earlier version to the latest. I do not know what version it was on as I have not upgraded it since I installed ATVFlash for the first time in June 2009. I had the AppleTV set to a manual software update and decided to run this yesterday. The download went fine and the AppleTV asked to reboot. I accepted and since then it has been stuck on the black and white Apple logo with a yellow/orange light blinking on the front. I tried this evening to load the new version of the ATVFlash and this has had the same result. I did see the ATVFlash logo and the software being updated and then was asked to reboot. It appears that the AppleTV is rebooting and then looping without actually starting. That is it has the Black and White Apple logo and then this goes off the screen goes black then blue (this is normally when I have a device connected but no signal) then back to the logo.
Any advice would be helpful.
