Used to communicate with the MStar bootloader via a serial (UART) connection to execute low-level recovery commands. Step-by-Step: How to Modify MStar Firmware
If the TV is completely "bricked" (no standby light, won't turn on), a USB update will not work because the bootloader is corrupted. You will need to flash the EMMC directly.
Incorrectly repacking a firmware file can permanently damage your TV's hardware if not handled carefully. Getting Started Extract the Bin: MstarBinTool-GUI to unpack your CtvUpgrade.bin Use a hex editor or image tools to adjust partitions like Use the tool to generate a new Most MStar TVs can be updated by placing the mstar android tv firmware tools

Reassemble modified components back into a flashable firmware file. MstarUtil / mstarutils : Another GitHub-based project ( skotopes/mstarutils Used to communicate with the MStar bootloader via
MStar system partitions are usually packed as sparse Android images.
Before delving into the tools, it's crucial to understand the target. MStar—now a part of MediaTek—designs the primary system-on-a-chip (SoC) found in many mid-to-high-range smart TVs. The official firmware (often a .bin or .pkg file) is a highly structured, multi-layered archive. It contains everything from the low-level bootloader (U-Boot) and Linux kernel to the full Android system partition (system.img) and user data areas. Incorrectly repacking a firmware file can permanently damage
: It strips the MStar header and extracts individual partition images like system.img and tvconfig.img .
