Mstar-bin-tool !!better!! May 2026

python mstar-bin-tool.py -x firmware.bin --extract kernel --output kernel.bin While not exhaustive, mstar-bin-tool works reliably on:

| Chip Family | Example Devices | Typical XOR Key | | :--- | :--- | :--- | | | Wyze Cam v2, Xiaomi 360 Camera | 0x51 | | MStar T20/T21 | Older IP cameras, Dash cams | 0xA5 | | Infinity 6 (IMG) | SigmaStar SSC335, SSC333 | 0x00 (No XOR) | | MSTAR 6A series | TCL Roku TVs (2016-2018) | Auto-detect | | Novatek? | Not supported (Different tool) | N/A | mstar-bin-tool

Note: Newer MediaTek chips (MTK 9xxx) use a different architecture and are not supported. Even with a good tool, firmware extraction can fail. Here is how to diagnose common errors. Error: "Unsupported magic bytes" Cause: The file is either not MStar, or it is encrypted with a non-standard key. Fix: Open the file in HxD or xxd . Look for MSTAR or SIGM . If missing, run binwalk first; it might be a U-Boot image directly. Error: "CRC Mismatch" Cause: The firmware is corrupted, or you passed the wrong XOR key. Fix: Try brute-forcing the XOR key: python mstar-bin-tool
