The latest release of MSTAR Bin Tool Master brings significant enhancements for engineers, technicians, and firmware modders working with MSTAR (now part of MediaTek) based TV, monitor, or embedded display firmware. This tool is widely used for unpacking, modifying, repacking, and flashing bin firmware images from MSTAR controllers.
The tool remains open-source under GPLv3 and can be obtained from the official GitHub repository:
git clone https://github.com/mstarlabs/bintoolmaster.git
cd bintoolmaster
make install
Pre-built binaries for Windows (MinGW), Linux (x64/ARM64), and macOS (universal) are attached to the v3.2.0 release page. mstarbintoolmaster updated
If you’re still using an older version, follow these steps to get the latest release (current version as of this article: v2.1.0).
One of the most praised additions is the Graphical Partition Map. Now, when you load a full binary dump, the tool visually displays: The latest release of MSTAR Bin Tool Master
You can now drag, resize, or move partitions without manually calculating offsets, reducing human errors in repacking.
The updated tool includes a command-line interface (CLI) module. Navigate to the install folder and run: You can now drag, resize, or move partitions
MSTARBinTool.exe --unpack firmware.bin --out ./extracted --auto-detect
This is perfect for automating firmware modifications across multiple devices.
Originally developed to unpack and analyze firmware images based on MStar (now part of MediaTek) SoCs, MSTAR BIN ToolMaster quickly evolved into a general-purpose binary dissection suite. It supports extraction, patching, checksum recalculation, header analysis, and even emulation stubs for embedded binaries.
The “ToolMaster” moniker reflects its ability to handle not just MStar-specific formats (like mstar.bin, mboot, pkg), but also custom vendor layouts, making it a swiss-army knife for IoT and TV firmware.
