Converts stock boot images and adds hidden root (accessible via netcat session), patches selinux and adds adb. Tested with Android 4.x - 10.x.

Options:

  -filename FILENAME, -fn FILENAME boot.img or recovery.img
  -stopboot                Device will halt on boot logo
  -justunpack, -ju         Just extract kernel + ramdisk (files will be in tmp/)
  -custom, -c              Stop in order to make changes (files will be in tmp/)
  -precustom, -pc          Stop in order to make changes before patches (files will be in tmp/)
  -forcesign, -fs [1|2]    Enforce signing with google keys, 1=Avbv1, 2=Avbv2
  -nopatch, -np            Do not patch anything
  -not_unpack_ramdisk, -nu Do not extract ramdisk (use with -np)

Installation:

Windows:

• You need to run makeramdisk.cmd twice. The first time being run, it will setup the environment.

Linux:

sudo apt install python3 python3-pip
sudo pip3 install -r requirements.txt

Usage:

Linux:

./makeramdisk.sh -filename boot.img

Windows:

./makeramdisk.cmd -filename boot.img

For AVBv1 : Output is boot.signed
For AVBv2 : vbmeta.img needs to be in the same directory. Output is boot.patched

ToDo:

Nothing, but maybe Android 11 needs more help :)
