**volantis** has a dummy header of size 256 bytes, which looks like this:

We have to trim the header before it can be recognized by our toy.
|
|
|
|
$ dd if=boot.img of=raw_boot bs=256 skip=1
|
|
|
|
Now we can work with 'raw\_boot'
|
|
|
|
$ cp raw_boot boot.img
|
|
$ gradle unpack
|
|
$ gradle pack
|
|

## Pixel XL (marlin)
|
|
|
|
**marlin** is a profile that adopts A/B system schema while still using Verified Boot 1.0 style boot image.
|
|
|
|
Due to the configuration "BOARD_BUILD_SYSTEM_ROOT_IMAGE := true", the embeded ramdisk in boot.img is actually used in recovery mode.
|
|
|
|
## NX606J
|
|
|
|
Thanks to the work by [CallMESuper], ZTE NX606J boot.img is also verified to be compatible with this toolkit.
