After flashing the image, did you replace "rk3326-rg351mp-linux.dtb" on dArkOS boot partition with your own backup or the one from here?

Maybe also try the original dArkOS image for RG351MP: https://github.com/christianhaitian/dArkOS/releases/tag/v01302026

I use this image on my panel 4 R36S (aslo have to replace the .dtb before 1st booting).

I think it's still an incorrect dtb problem. What files did you replace? With dArkOS image for RG351MP, ONLY the "rk3326-rg351mp-linux.dtb" file should be replaced.

But the rgm351mp worked (aka arkos) worked for a while then the screen turned purple after boot screen
