Got my new Vero 4K, set it up, pointed it to my media.
Then i copied my own advancedsettings.xml (database etc), plugged it in, worked, with my media and my database.
Moved it to other room, it asked for upgrade to 19.x, i agreed, wait a while until it rebooted.
it would go do a database update. (but i already had an updated database running), so it kept on for hours and hours.
i plugged it out, plugged it in, after the osmc splashscreen only black screen.
So how can i go back to the default 18.x install?
