The system.img file in MStar firmware is usually stored in either a sparse Android image format or a raw ext4/SquashFS filesystem format.
Once modifications are complete, unmount the directory and convert the raw image back into a compressed sparse image:
Inside this monolithic file lies a complex layout consisting of:
aescrypt2 1 recovery.img recovery.img.dec hex:0007FF4154534D92FC55AA0FFF0110E0
Repacking MStar Android TV firmware is a technical process involving unpacking a .bin upgrade file, modifying its contents (like boot.img or system.img ), and rebuilding the package for flashing.
Recreate rootfs image
mkdir system_mount sudo mount -o loop system_raw.img system_mount/ Use code with caution. Step 3: Modifying the Firmware Content
: Specifically used for decompiling recovery.img and boot.img after they have been extracted from the main firmware bin.
