>by using Gnome Disks to "restore" it to eMMC but the eMMC can`t boot. Not even the LED is turning on.
almost suggests that gnome disks doesn't copy uboot (1st 16M)
>and the uboot img-s to the eMMC, then the LED swtiched on but no boot.
does the caps lock LED toogle?
Do you have a vt? (control-alt-F3)
Do look closely,, I have had a vt where the letters were barely visible,
very tiny, very faint. I don't think setfont -d works for debian (which is what q4os is based on)
Clearly the emmc uboot is either working or blank since you have mrfixit SD boot
(boot rom search order for idbloader is SPI, emmc, SD, 1st one found is one that is used)
