Newer MStar kernels use LZ4 instead of gzip. The updated tool decompresses these on the fly.
While Beta 3 is the best free option, here are alternatives:
| Tool | Pros | Cons | |------|------|------| | MStarBinTool GUI (by Xander) | Good for beginners | Last updated 2021 | | mstar-dump (Python) | Works on Linux | No encryption support | | Custom flashing tools (e.g., Multiloader) | Direct flash without unpack | Cannot modify firmware | | Firmware Mod Kit | Repacks squashfs | MStar header is often lost |
If Beta 3 fails, try combining it with binwalk to manually carve partitions.

If you run a TV repair business, always obtain written permission from the manufacturer or clearly inform customers of the risks.
Early attempts to unpack MStar BIN files involved hex editors and manual partition extraction—a tedious, error-prone process. Then came:
Now, the "updated" Beta 3 version has been circulating on forums like 4PDA, XDA-Developers, and FreakTab. This release fixes critical bugs present in earlier betas.
Unlike standard Android devices that often use standard ext4 partitions or generic update.zip packages, devices running on MStar chipsets (commonly found in Smart TVs like Samsung, LG, and various no-name Android boxes) often utilize a specific proprietary partition structure. Newer MStar kernels use LZ4 instead of gzip
These .bin files are usually comprehensive firmware dumps. They don't just hold the OS; they hold the bootloader, the kernel, the recovery image, and the system partition all packed into one binary blob. Without a specialized unpacker, this file is just a jumble of hexadecimal data.
Many 2022-2024 firmwares use dynamic XOR keys. Beta 3 now auto-detects 8, 16, and 32-bit XOR patterns without manual hex editing.

The original Beta 1 and Beta 2 releases were functional but quirky. Users reported three major issues:
Beta 3 (Updated) claims to fix all three. According to the changelog posted on the developer’s Git:
"Refactored header parser for Mstar V56, V59, and V69 platforms. Added fallback when CRC32 mismatches—now prints warning but proceeds. Static linking for better cross-distro compatibility."
