The tool is essential for firmware "cooking" or reverse engineering: Header Script Analysis : Automatically finds and saves the ~header_script , which contains the mmc write.p commands used by the bootloader to flash the device. Encryption Support : Manually encrypts or decrypts images using logic if the firmware is RSA/AES signed. Configuration Flexibility files (like mstar-bin-tool

The tool recalculates the CRC and corrects the XOR table. If you omit --header , it will create a fresh header, which might brick a device expecting a signature.
