After all call mkdtboimg.py create dtbo.img dts/*/*.dtbo inside of out/arch/arm64/boot/

~/android/lineage/system/libufdt/utils/src/mkdtboimg.py create dtbo-lineage.img ~/android/lineage/kernel/xiaomi/tucana-out/arch/arm64/boot/dts/*/*.dtbo

To extract boot.img: ./imjtool.ELF64 boot.img extract (extracts the dtb file too). ~/git/mkbootimg/unpackbootimg -i boot.img -o boot/ where git/mkbootimg is from https://github.com/osm0sis/mkbootimg.git

to repack something like:

DIR=boot
DTB=extracted/devicetree.dtb # from imjtool above
~/git/mkbootimg/mkbootimg \
	--kernel $DIR/$DIR.img-zImage \
	--ramdisk $DIR/$DIR.img-ramdisk.gz \
