Dump Mstar Unpack Repack Tool [repack] -

: Never modify a firmware file without keeping an untouched, original copy of your working stock firmware safely stored elsewhere.

Connect an RT809H, CH341A, or similar ISP programmer to the TV mainboard via the VGA/HDMI ISP port or directly to the eMMC/Nand chips. Open the programmer software and auto-detect the chip.

The Dump Mstar Unpack Repack Tool is a specialized utility designed to deconstruct (unpack) and reconstruct (repack) firmware images used by Mstar-based devices.

Typical workflow

If your device uses vendor-specific AES keys, extract them from MBOOT: python secure_partition

Ensure all altered partition files are placed back into their precise original extraction directories. If the file size of any partition expanded during modification, update the size values inside your config.ini or packaging script to match the new byte sizes exactly. Phase 2: Recompiling the Master Binary File Open your command terminal and call the repack routine: mstar_tool.exe -r ./extracted_files/ NewMstarUpgrade.bin Use code with caution. (Or via the Python alternative) python mstar_repack.py ./config.ini NewMstarUpgrade.bin Use code with caution.

: Replace the generic boot video or image files located in the media partition to personalize the TV startup sequence.

The utility will output an index file listing the exact byte offsets, partition names, and lengths detected inside the file. Phase 3: Executing the Extraction Sequence With the offsets mapped, initiate the extraction sequence.
