Many thanks for your efforts and help with yours and with Demetris images.
I have an M8S tv box (clone) - 2G ram, 8G rom, 100M ethrenet, BCM4330X wifi
I could successfully boot and install your LibreELEC-S812.LAN_100.arm-17.3.img.gz on an SDram and USB stick, however, this (and also previous builds) couldnt run tvheadend42. I could install and use only tvheadend4 and have faced some DVB sudio decodin issues.
I have tried LibreELEC-S812.Test.arm-17.3_20170614.img.gz on a USB stick on the same tv box and could install it on a USB stick. The first problem which I have faced is that there was no LibreELEC repository available and I couldnt install and test tvheadend42 and an HTSP PVR client.
Later this week, I will try and test this image also o another ENY M8S tv box I own - 2G ram, 8G rom, 100M ethernet, AP6330 wifi. In the past I couldnt install any of yours or Demetris images onto an SDram with this TV box (some have been stucj with the M8S logo and some have reported a corrupted file system).
