That tvbox looks like a clone of some mecool. Try the dtb that most closely matches your tvbox.
Tried 13 different DTBs (each with different results) and I think the problem is that I misread the Title: S9xxx with triple x means that my S905 is just not supported.
Hey there, I have this mounting-problem at boot as well:
*** Error in mount_flash: mount_common: Could not mount LABEL=LIBREELEC ***
### Starting debugging shell for boot step: mount_flash... type exit to quit ###
Device: MagicBox TVPC
Previously running LibreELEC-S905.arm-8.2-8.2.3.1 with gxbb_p201.dtb
Tried running:
LibreELEC-ARMv8.arm-9.80-devel-20200717085327-569f834-amlg12.img
LibreELEC-ARMv8.arm-9.80-devel-20200717121539-569f834-amlgx.img

The default uEnv.txt is using "/dtb/amlogic/meson-gxbb-wetek-play2.dtb", which is starting, but the Remote is not working, LAN is not connecting and everything seems laggy. Since I've used "gxbb_p201.dtb" before, I expected "/dtb/amlogic/meson-gxbb-p201.dtb" to work for me, but it keeps generating the error from above.
What am I doing wrong? The SD card doesn't seem to be broken, since flashing the old LibreELEC 8.2 works perfectly.
