Tools needed: git, git-lfs, xattr, android-tools

First do: git clone https://github.com/phhusson/ulefone-armor-9-gsi.git

Remember to: "git lfs pull" to get the large files.

Then get the original system.img file you want to patch with the FLIR stuff.

To build the new s.img: sudo bash generate.sh <original-system.img>

Now you can flash that file with: fastboot flash system system.img
