May i suggest instead of downgrading your Emote you try to upgrade your H9000 from its frontpanel.
I was in the same catch 22 sitiation .
Mine was crashign like 9 times before i gave up and look into the menu…
Go into the system on the H9000, make sure you have it connected to internet of course.
There you will find an update button and you can navigate to the latest beta which works fine with the latest Emote
I think it shoud be rectified by Emote allowing for updates of the H9000 regardless of either version.
