@horiatm welcome to armbian and the TV box club. Since this is your first post, I want to point you to the 'Please Read First' post: https://forum.armbian.com/topic/16407-please-read-first
I have never heard of your box before. In doing some searching, I don't see anyone ever posting about it in the armbian forums either. Actually I can't find much information at all about the box. Therefore it is unlikely that anyone around here is going to own one or have any direct experience with it. Therefore while we might be able to give you some general guidance, you are likely on your own trying to hack armbian onto your box.
If you are looking for help, more information would be helpful. Like where are you downloading the images you are trying from? What steps/instructions are you using to attempt to get this working. Simply saying 'Tried to boot..' doesn't give us much to go on. Things like what dtb's you have tried (and how) would be helpful.
