Generate su variant from any:
sudo bash su.sh system.img
The output for above would be s-su.img.
Generate secure variant from any:
sudo bash securize.sh system.img
The output for above would be s-secure.img.
Generate A64 AB VNDKLite from A64 AB:
sudo bash lite-adapter.sh 32 system.img
Generate ARM64 AB VNDKLite from ARM64 AB:
sudo bash lite-adapter.sh 64 system.img
Generate ARM A-only from ARM AB (deprecated since Android 12):
sudo bash run.sh 32 system.img
Generate ARM64 A-only from ARM64 AB (deprecated since Android 12):
sudo bash run.sh 64 system.img`
The output for above would be s.img.
Windows users (with fairly recent hardware and Windows version) can run these scripts on Docker, without having to set up a full Ubuntu installation/VM. For people who are new to Docker, below are crude steps to e.g. securize an image with it:
- Install Docker Desktop. When prompted to select between WSL2 or Hyper-V backends, choose WSL2.
- Make sure Docker is in Linux Container mode (it should be by default) - right click the tray icon, one of the menu items should say "Switch to Windows Containers", don't click it.
- Pick/make a folder (e.g.
C:\out) and put your GSI image there (e.g.system.img). - Only if on Hyper-V backend: open Docker Desktop - Settings - Resources - File sharing and add the above folder. This settings won't be present on WSL2 backend.
- Open Command Prompt (
cmd) and run:
docker pull ubuntu
docker run -it -v C:\out:/out --privileged ubuntu
This starts a Ubuntu container and mounts C:\out to /out inside it.
- You should now be in a privileged (
#) Ubuntu terminal. Run:
apt update
apt install -y git xattr
git clone https://github.com/AndyCGYan/sas-creator
cd sas-creator
bash securize.sh /out/system.img
mv s-secure.img /out
exit
You can now flash the securized image C:\out\s-secure.img.
Note: intentionally not using Dockerfile.
