This training video demonstrates how to use the DMURTP software to extract and unpack dump files from eMMC storage: Dump Mstar Unpack Repack Tool

2. Unpack specific image

./mstar_tool unpack -i extracted/system.img -o system_mod/ The Dump Mstar Unpack Repack Tool (also known

Deep Dive: Manual Unpacking (When tools fail)

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

3. Make modifications (e.g., add file, remove app)

cp myapp.apk system_mod/app/

"Checksum Error" on Boot

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.
