Hi Trilok,


that sounds great, thanks for looking into it! Could you also check why 
using a boot.img header version 2 (with a dtb embedded into the boot 
image using the --dtb option in mkbootimg) seems to be broken on 8350, too?

I get a "your device is corrupted and will not boot" error, even though 
I disabled vbmeta/vbmeta_system and performed the same steps described 
in this commit message to dtbo/vendor_boot. It worked fine on 
4.19-release SoCs without vendor_boot (8250, 6350), but it seems it 
doesn't anymore.
