@ Djon With the Ugoos AM6B Plus, I would use either the current nightly build or the CPM A14, which includes an older nightly build. I use the CPM A14 build in flash and the current nightly build via SD card.
Dovi.ko always has to be there, in my case also the remote.conf for the UR01 and the remote2.conf for the UR02 as well.
