IsHacker003/microG_no_sigspoof — reverse-engineered prompt

Build me a small Android mod project that lets people install microG on a ROM that doesn’t support signature spoofing. I want it to create a flashable systemless module for Magisk, KernelSU, and APatch, using only shell scripts and a Makefile, no native code or extra bundled apps.

The build should download the latest official microG GMSCore, Companion, and GSFProxy APKs, patch them with the saved Google signature blocks using apksigcopier, then package them so they install as system apps. Make it clear these APKs should not be installed as normal user apps.

Please include simple build commands for making the module, building the individual APKs, and cleaning the output. Add strong warnings that users must remove GApps first, that Android 16 is not supported, and that recovery flashing is unstable if you include it at all. Keep the project lightweight and easy for beginners to use.
