Just tested 8.0-8.0.1h with gxm_q200_2g.dtb on a Nexbox-A1 and all seems fine, including my IPTV subscription. I'm happy to have a functional, inexpensive box on which to run a second instance of LibreELEC. Will keep checking in here hoping for a release with the 'real' Mali-T820 libs but have to give props to kszaq for finding a way to get this done!
