The Dump Mstar Unpack Repack Tool (also known as DMURTP or Dump Mstar Unpack Repack Tool Pro) is a specialized software utility designed for technicians and developers to manage and modify firmware for televisions and devices using Mstar chipsets.
This training video demonstrates how to use the DMURTP software to extract and unpack dump files from eMMC storage: Dump Mstar Unpack Repack Tool
./mstar_tool unpack -i extracted/system.img -o system_mod/ The Dump Mstar Unpack Repack Tool (also known
Sometimes, generic tools fail due to XOR encryption or custom headers. In that case, you use a hex editor (HxD) to look for the SquashFS magic bytes (hsqs or sqsh). You copy from that offset to the end of the file and run: Requirements
unsquashfs -d rootfs custom_squashfs.bin
cp myapp.apk system_mod/app/
Cause: The repack tool used the wrong algorithm (e.g., standard CRC32 instead of Mstar's reverse CRC). Solution: Use only tools explicitly named "Mstar Repack" (e.g., version 2.0.7 by 'MadHacker'). Avoid generic hex editors for checksum fields.
