Mstar Android Tv Firmware Tools Repack
Mstar TVs have a bootloader that checks for RSA signatures. If you repack a .pkg without the private key, the stock recovery will reject it. To circumvent this:
Mount and edit:
mkdir sys_mount
sudo mount -o loop system.img sys_mount
# Remove bloat, add files
sudo umount sys_mount
Then repack to sparse image:
img2simg system_ext4.img system.img
If you have a .zip file, extract the contents to a folder. You will likely see a file named MstarUpgrade.bin or similar. If you have a raw NAND dump (backup), you are already halfway there.
The standard workflow for repacking an MStar Android TV firmware is as follows: mstar android tv firmware tools repack
Signing (Optional/Device Specific): Some MStar TVs require an RSA signature verification. If the device has an unlocked bootloader, this step is ignored. If locked, the repacked image must be signed with the manufacturer's private key (usually unavailable) or the verification checks must be patched out of the bootloader (advanced exploitation).
MStar (MonStar) chips were widely used in older Android TVs and TV boxes (such as the MSO9180, MSO9280, and MSO9830 series). Unlike Amlogic or Rockwell devices, MStar firmware modification requires a specific set of tools and a precise methodology due to the unique MStar partition table format (MBOOT).

"Repacking" firmware usually refers to extracting a factory update image (typically a .zip or .img file), modifying specific partitions (like system.img, boot.img, or recovery.img), and then repacking it all into a flashable file.
