This repository provides a comprehensive toolkit for Android ROM modification, featuring a menu-driven interface for extracting, modifying, and repacking Android system images. The architecture is modular and script-based, with main entry points in start.sh (and language variants) that dispatch to specialized scripts for operations like image extraction, modification, and flashable package creation. Key workflows involve setting up isolated workspaces, processing images via filesystem-specific tools (ext4, f2fs, erofs), applying modifications (debloating, feature additions), and generating flashable ZIP or Odin TAR packages. The toolkit integrates numerous open-source utilities for low-level operations, including boot image manipulation (AVB, DTBO), filesystem utilities, and APK optimization tools. While functional and well-organized for its niche purpose, the reliance on external binaries and AOSP-copied components introduces maintenance considerations.
