Libreelec is working very good on the MXIII only i have 1 problem and that is that i cannot turn it on when i turn the box off within kodi.
It does go to sleep mode but then i cannot turn it on, not with the remote and also not with the power button.
I had the same problem with the M8S (CS_812M8_V1.3). The manufacturer incorrectly implemented the shutdown method in the bootloader, unfortunately you can't really do anything about it. 
I tried to bring it back to life but I regret wasting so much time on this honestly, wasn't worth it.
I'm sad to hear that. 
Unfortunately, none of the third-party providers officially support Kodi (e.g., Youtube, Spotify, Netflix, Amazon, HBO Go, etc.), so all of these add-ons are made by the community. They will never be as “good” as the official Android app created by the manufacturer, but there are some that still have an advantage (e.g. "No ads").
Hello Darth,
I have A Minix X8h Non Plus Box (S802)and your Rom Works Great For Me. I do have to mention that I use an external Usb Ethernet device for wired ethernet. I don't use wifi or have not tried the built in ethernet. Everything other than what I mentioned works. Great job and thanks.
Okay, his name is datrh and not "Darth". If you really tested his image, you wrote in the wrong topic.
However, he never made a 9.2.6 image, so... Whose firmware are you using now? It is not clear.
