you should definitely use the M8 builds. the box isn't compatible with other variants in terms of peripherals.
I'm using the build from here LibreELEC-S802.M8.arm-8.0.RC4: LibreELEC-S802.M8.arm-8.0.RC4.img.gz | by Demetris. for MXQ TV Boxwhat's the behaviour you have from your box? maybe I could assist with a step-by-step.
Thanks for the offer!
The latest build released today is working a treat!
