It is an Android TV box provided by Internet Provider in my Country. They called it 'Fiberhome' HG860P.
It has an eMMC and micro sdcard reader and has capability for multi boot out of the box.
On eMMC, installed Android TV ver 6.
I got referenced from Youtube, build an image to a micro sdcard and just plugged it to the box.
Armbian runs OK, LAN OF, WIFI OK, SSH OK, except for when I left it idle for about an hour or so, I couldn't SSH again, but ping worked OK.
Connection to box made via LAN and WIFI.
Have to turn it OFF and ON again to made it worked again.
