Received my $149USD Dune HD Pro Vision 4K today.
I used the pen drive from my Dune Homatics box that already had CoreELEC on it. However, I had to replace the device tree with this one >> sc2_s905x4_4g_1gbit.dtb <<.
Since I was not sure where the “reset button” was located, I used this app “Reboot_to_CoreELEC_3.0.apk” and it worked like a charm.
Since this pen drive was used on my Dune Homatics, it already had the IR remote working, so I had to use that remote, and it worked well.
Tomorrow, I will install CoreELEC onto a microSD card and use that. Not sure there is a remote.config for the Dune remote.
