Ugoos X4Q Extra: No Ethernet connection after starting after it was without power and then shutting down = reboot

But that’s no use, if the USB interface is dead.
But that was only the case with the “general” S905X4 device tree.
Otherwise I would also have a small USB keyboard here, but that didn’t work well for me.
I would prefer a remote control.
But I think, that’s not the problem in this case.
(In general, I’m already looking for a decent USB remote control, but that’s another story…)

No, you misunderstood that. My English is bad too, maybe it got lost in the translation somehow, what I meant! The “default setting” after starting, after it has been without power, is, that the slider is set to DISABLED for Wired Networks.
But that’s wrong. It’s supposed to be activated. So I tried to switch it to Activated, but that doesn’t work.
After another reboot (without it having been without power in between), Wired Networks is activated again (and of course I’ll leave it like that!).

I only had a quick look, but I really liked the colors of the OSD!

I didn’t know, that there are different dovi.ko for the different CoreELEC versions (ng, ne, no).
Where can I find them, e.g. for no (and the Ugoos X4Q Extra)?
I only know the link that is included here in the explanations for the NG image:

And then I would still have the problem, that I can’t play Dolby Vision Profile 7 (FEL 7) with the NO image (if my files even support it)? Or would it work with the right dovi.ko?
