The Apple TV flashes the apple logo every two or three seconds and that is it.
It sounds like a version older than 4.0 is being installed.
To rectify this try the following.
- Remove all copies of aTV Flash (folders, files, everything) from your computer.
- Download a fresh copy here: https://www.atvflash.com/account.php
- Format the flash drive to be used as described here: http://wiki.atvflash.com/index.php?title=Reformat_Flash_Drive
- Install aTV Flash as before. The current 4.0 version will be installed, and will overwrite the outdated version that is on the AppleTV.
I finally got it to boot but unfortunately all I get is errors when trying to run XBMC or BOXEE.
Sometimes it just decided to reboot out of the blue
once you get it loaded and rebooted to the new ATV 3 menu, if you haven’t you need to run the smart installer, then you have to redownload boxee and xbmc (i ran the alpha version) to get them to work. do not run the launcher for you should have the latest beta version of 3.2b which is needed for xbmc (can check by going into “about” on the xbmc / boxee menu). not sure on how well boxee runs. i only use xbmc and nito with no issues.
