Hello!
Question to the OP:
Is this: https://www.amazon.de/Android-Quad-Core-Cortex-A53-Enternet-Bluetooth/dp/B0BYCK85LB the type of settopbox you're using?
If so, where did you get the image you're using?
I'm using an Odroid C2 for my mediaserver, but with passive cooling it runs damnably hot and with active cooling it's not fit to run in my living room.
Before the C2, I had an Mecool M8S Pro W, for several years, but the S905W chipset is no longer supported and I need a series 6 kernel to run it, so I was looking what the Settop boxes offer these days and found your thread.
It reads as if the basic functionality was reached almost out of the box, what is what I am looking for.
