What is the or chipset number of your Mstar device?
# Mount/unsquashfs if it's a standard format after unpack header removal unsquashfs rootfs_mod.squashfs # ... modify files ... mksquashfs squashfs-root/ new_rootfs.squashfs -comp lzma
Ensure you have Python installed on your system. Clone or download your chosen script into a dedicated working directory alongside your firmware file. 2. Execute the Unpack Command
Stores text-based configuration variables for the bootloader. Dump Mstar Unpack Repack Tool
Use commands like mmc read to copy partitions into RAM, and then use usb start and fatwrite to dump those memory segments directly to a FAT32-formatted USB drive. Phase 2: Unpacking the Firmware Bin File
: Breaks down full CtvUpgrade.bin or MstarUpgrade.bin files into individual partition images such as MBOOT , boot.img , recovery.img , and system.img .

# Unpack MStar-packed rootfs partition ./mstar_unpack -f extracted/rootfs.bin -o rootfs/ mksquashfs squashfs-root/ new_rootfs
Reads raw storage dumps or official upgrade packages.
The most common use case is aesthetic. If you want to change the manufacturer’s splash screen to a custom image, you need to unpack the firmware, locate the logo partition (usually logo.bin or a similar JPG/BMP resource), swap it, and repack the firmware. 2. Enabling Hidden Features
Use an image mounting tool (like OSFMount on Windows or standard loop mounting on Linux) to open system.img . Navigate to /app or /priv-app to delete unwanted factory applications.
If you would like to proceed with your firmware modification project, please share a few additional details:
Firmware customization allows developers and tech enthusiasts to optimize smart TVs, modify system applications, and update boot animations. A core processor family found in many budget and mid-range smart TVs is Mstar (now a part of MediaTek). To modify these devices, you must understand how to manipulate their firmware files, usually distributed as bin or pkg images.
