Rikomagic RK25 and CoreELEC

I also have this box, it sells on aliexpress by different name, S78

Owing on posts on forum, 4gb versions have no problems with coreelec, for example, x88_king_rev_a is compartible.
2gb version - all dtb files included in coreelec, are not compartible, box just freeses on logo.
Ive also tried nightly images of libreelec (kodi 20 alpha), and found dtb able to boot device - odroid-n2.dtb but unfortunately, usb ports are not powered, and not working. Weird, that dtb with the same name included in CE doesn’t boot device.
Could someone help please? I’ve bought this box just to use CE, but it was suprise that 2gb version won’t be compartible with CE
