Then, you need to flash it on the device and get rid of all the
vendor_boot/dtbo mess:
fastboot flash boot boot.img-sony-xperia-pdx215
fastboot erase vendor_boot
fastboot flash dtbo emptydtbo.img
fastboot reboot
Where emptydtbo.img is a tiny file that consists of 2 bytes (all
zeroes), doing
a "fastboot erase" won't cut it, the bootloader will go crazy and
things will
fall apart when it tries to overlay random bytes from an empty
partition onto a
perfectly good appended DTB.
I will check on this part and see if we can make simpler support
fastboot erase dtbo without the extra emptydtbo.

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.
