MStar upgrade binaries consist of two main components: a (header) and a payload .

Open the firmware file in a hex editor (like HxD) to manually locate the U-Boot string patterns and manually adjust the offset parameters inside your tool's configuration file. Important Safety and Legal Notice

Extract the mstar-bin-tool-master folder directly to the root of your C: drive to avoid path-length errors. Inside that folder, create a working directory (e.g., C:/1/ ) to store your firmware.

Re-download the original MstarUpgrade.bin package. Ensure that your download completed entirely and verify the file's MD5/SHA256 hash if provided by the manufacturer. Error: "Unknown Partition Alignment"
