How to update to beta6 when it is released

How do I update to beta6? update via atvblack.exe/atv interface??

Usually if you’re already running aTV Flash (black) on your AppleTV all the new features can be installed through the Maintenance --> Manage Extras menu. Most likely Maintenance will need to be updated first for the items to install properly… pretty straight forward after that. - items are visually marked by “UPDATE”.
