I'm suggesting you to take the cheap Raspberry Pi4 and it'll do everything you need for Kodi. But the sat box must be good.
In my current experience base, I continue to recommend dm920 (unfortunately, PLi is not supporting it).
From PLi supported boxes I don't know what to recommend, because there's something wrong with everybody. The main problem seems to be the manufacturer's drivers/ all these boxes have deficiencies that piss users off.

OK, I don’t have H10, I just wanted to be sure, that your setting is correct.

If the Simplink (LG) is not allowed on the TV side, it can't work, turn it first on!

Then play with interval (delay of order) on box side:

Setup->System->Audio / Video->HDMI-CEC setup->Minimum send interval->

and set it to ‘100 ms’

Hi, about 

3 HdmiCEC does not work with LG 55UJ630V 4K UHD TV

 

You could try this after the HDMI-CEC is enabled:

Setup->System->Audio / Video->HDMI-CEC setup->Minimum send interval->
and set it to ‘100 ms’

and then please try it again and please report back, if it works for you!

OpenVision this part of CI+ is not as good as you think. Just for info.

Yes, recovery mode is for dm9x0 boxes, I haven't seen it on the others. This is not a question to PLi.

Winter Swimming (today):

I'm using Debian, it works well. I'm not saying it's the best, but it works and it's been tried that it works.

Dimitrij, no, you misunderstood. I said it's not good enough, if even one other part is closed and there are so many, also at the core side.

OpenVision Enigma2 repository it's totally useless until one bitt is closed.

From OV statement:

 

Lots of our git repositories are now private and no self builing is possible thanks to source steallers.

And I'm not offended to PP, that he banned me from OV board. He knows better what he's doing and who he builds it for.

Then goodbye, Sir, and sorry for that.

Maybe they keep that part closed....

That means partially closed, that means closed IMHO. But I'm just a little tester here, I'm not in favour or against, I wish it would improve, the users don't fool around and everyone would be happy. On the other hand, I understand why Prince wants to do this. OV has done great things, it's clear, but there are things I don't like, but I'm just one of many here.

It's not useless, it contains valuable feedback.

Thank you for your beautiful report and your effort, let us appreciate it very much. 
I appreciate PLi stability and good language support, which is partly incomplete in case of Dreambox, such as subtitles and audio selection automatically by selected language is in PLi well solved.

In Open Vision I hate non-stability, but I love their very big innovation (I'm a tester there). PLi is over his head for stability.

I will do today your Lithuanian language!
