According to the official documentation, the tool includes several specific scripts for different tasks: for unpacking MStar BIN firmware, pack.py for repacking it, extract_keys.py for retrieving AES and RSA keys from the MBOOT, and secure_partition.py for handling encrypted images. By using these scripts, a user can break down a large BIN file into its constituent parts (like system.img , recovery.img , and MBOOT.img ), modify the Android system, and then repackage the firmware for flashing [13†L9-L11].
Ever wanted your TV to greet you with a custom animation instead of a corporate logo? You can extract the resources, swap the images, and repack. mstar-bin-tool

Many modern MStar builds have SECURE_BOOT enabled, meaning boot.img and recovery.img are encrypted with AES and signed with RSA private keys.
Before flashing experimental builds, hardware enthusiasts should solder a UART serial connection to the TV's mainboard. This grants access to the Mboot> console, allowing you to monitor boot failures in real-time and force-flash a recovery image if the display remains black. Packing Firmware To create a new firmware, you
If your firmware's boot.img or recovery.img appears encrypted (common in newer builds), you need to extract the AES and RSA keys from the MBOOT.img using the following command:
Summary
Use extract_keys.py to target the MBOOT.img partition and grab the keys: python extract_keys.py ./unpacked/MBOOT.img Use code with caution. Copied to clipboard
