Then:
I downloaded the stable version of the NG version, file:
“CoreELEC-Amlogic-ng.arm-21.2-Omega-Generic.img.gz”
I extracted the IMG file and write it to the USB Flash Drive.
I went to the “device_trees” folder and copied the file “sc2_s905x4_sei_smb_280” to the root of the USB Flash Drive.
I renamed the file “sc2_s905x4_sei_smb_280” to “dtb.img”.
I downloaded the “dovi.ko” file for the S905X4 SoC, and copied it to the root of the USB Flash Drive.
Is everything correct?
Is there any problem using “Reboot to CoreELEC”?
I will run/open CoreELEC through it, for me it is better than using other methods.
Thank you for the patience and for the help.
