options:¶

-h, --help

show this help message and exit

--boot_img BOOT_IMG

path to the boot, recovery or vendor_boot image

--out OUT

output directory of the unpacked images

--format {info,mkbootimg}

text output format (default: info)

-0, --null

output null-terminated argument strings

Output format:

* info

Pretty-printed info-rich text format suitable for human inspection.

* mkbootimg

Output shell-escaped (quoted) argument strings that can be used to reconstruct the boot image. For example:

$ unpack_bootimg --boot_img vendor_boot.img --out out --format=mkbootimg |

tee mkbootimg_args

$ sh -c "mkbootimg $(cat mkbootimg_args) --vendor_boot repacked.img"

vendor_boot.img and repacked.img would be equivalent.

If the -0 option is specified, output unescaped null-terminated argument strings that are suitable to be parsed by a shell script (xargs -0 format):

$ unpack_bootimg --boot_img vendor_boot.img --out out --format=mkbootimg \

-0 | tee mkbootimg_args

$ declare -a MKBOOTIMG_ARGS=()
$ while IFS= read -r -d '' ARG; do

MKBOOTIMG_ARGS+=("${ARG}")

done <mkbootimg_args

$ mkbootimg "${MKBOOTIMG_ARGS[@]}" --vendor_boot repacked.img
