Hey Demetris, gret work.
I have had amlogic.ru 7.0.2 (M8S) build on my S812 MAtricom Gbox Q2 for a while and has always worked great but work has stalled so its upgrade time. I tried your LibreELEC-S8X2.M8S-PLUS.arm-8.0.2 build and everything went through fine including internet connection however my remote will not work.
I then tried LibreELEC-S8X2.arm-8.0.2a-MXIII-PLUS and after reboot my device is now stuck on the amlogic chip screen so I obviously installed wrong version. Which version should i use and how can i install now i dont have samba access due to kodi failing to start?
