Reset RGB 8-bit after rebooting (android9-20200827)

Reset RGB 8-bit after rebooting.
Where configuration files are stored?
There used to be here: sys/class/display/HDMI/color
echo mode=1 > sys/class/display/HDMI/color

What to apply the init.d script for TUNER “COLOR” after rebooting?


setting anything will not change it from RGB 8Bit, sometimes selecting any other setting will turn off the picture but the box remains on, and a restart is need to return the picture

I want to enable forcibly through the init.d script.
How to do it, where is the file “Color”?
