Modifying the unpacked files is easy (swap a PNG in /usr/share/logo/ ). The hard part is rebuilding the image so the Mstar bootloader accepts it.
Contains the core system binaries, libraries, and initialization scripts (often formatted as SquashFS or CramFS). However, with great power comes great responsibility
However, with great power comes great responsibility. Use these tools only on devices you own, and always prioritize backup and safety. As the embedded systems community continues to reverse-engineer and improve these utilities, the barrier to entry lowers—but the fundamental requirement of technical caution remains.
Scenario: You want to change the boot logo on a Hisense TV (Mstar MSD368).
