: Using extract_keys.py , users can retrieve AES and public RSA keys from the MBOOT binary. This is essential for decrypting or encrypting secure partitions like boot.img and recovery.img .

(often downloaded as the master branch archive mstar-bin-tool-master ) is an open-source, Python-based utility command-line suite used to reverse-engineer, modify, unpack, and repack MStar binary firmware files ( .bin ).

Modifying device firmware carries a high risk of bricking your device (making it unusable).

: Extracted files (e.g., system, user, or configuration images) ready for customization, malware auditing, or deep file-system tweaks. Packing and Recompiling Firmware

The output folder will contain the individual partition images and a ~header_script file, which describes how the partitions are structured. 2. Packing Firmware

Creating customized firmware with modified launch programs, updated libraries, or pre-installed tools.

: The reverse engineering component. It takes customized partition components and wraps them back up into a flashable firmware binary matching the original MStar structure.
