Hello,
I upgraded my mxIII plus 2G with LibreELEC-MXIII_Plus.arm-LE9-Kodi_18.6.tar
Update went smoothly ! Great job !
Everything seems fine, except eth0 mac address is 1E:00:00:00:00:00 (this is an issue having multiple boxes).
I can't change eth0 mac address, i've tried with an udev rule and with a systemd service but i'm stuck with mac 1E:00:00:00:00:00
Edit :
Finaly, it works with systemd script ( see How to change duplicate MAC Address )
Thank you for your great job.
