I assume CoreElec have the same problem?
"CoreELEC 19 becomes the active development branch and it is based on CoreELEC 9.2.6 Amlogic-NG. So all devices that support Amlogic-NG 9.2.6 will also support CoreELEC 19.0-Matrix. There is currently no support for GXBB and GXM (S905 and S912 respectively) based devices as these SoC are EOL and there are multiple devices with newer SoC available."
