: Since MStar devices support encryption, simply having the .img files isn't enough. boot.img and recovery.img are often scrambled. mstar-bin-tool provides secure_partition

: This script is used to encrypt images and generate sign files.

: Recompiles firmware components back into a single .bin file using a configuration file (e.g., .ini ) to define the structure. Once you have modified your target files (like

The output will be a directory (usually called output or based on the bin name) containing the extracted images: boot.img , system.img , recovery.img , and a header.bin . 2. Modifying the Firmware

Splits a monolithic MStar firmware container into its individual partition images (such as kernel, rootfs, and bootloader).
