Scenario: You want to change the boot logo on a Hisense TV (Mstar MSD368).
Change the contents (e.g., swapping a boot logo, adding an app, or editing configuration scripts).
unsquashfs -d rootfs custom_squashfs.bin
Ensure the names of your new image files match the original filenames exactly. Run the repack command provided by the tool: python mstar_repack.py config.txt MstarUpgrade_Modified.bin Use code with caution. Dump Mstar Unpack Repack Tool
If the device gets stuck on the logo after flashing, a modified partition (usually system.img ) might have incorrect file permissions or file sizes. Re-verify your modifications on a Linux environment to maintain correct symlinks and permissions.
You added a 5MB logo, but the original partition was only 4MB. Solution: You cannot increase partition size without recompiling the kernel's DTS (Device Tree). You must instead compress the logo or replace a smaller asset.
Create a working folder, for example, C:\MstarWork\ . Scenario: You want to change the boot logo
A graphical interface version that simplifies partition selection and config generation. Basic Workflow for Modifying Firmware 不染尘/mstar-bin-tool - Gitee
Add or remove pre-installed Android applications ( .apk files). Change the boot animation or splash logo screens.
The ability to parse varying Mstar header formats across different chip generations (e.g., MSD6A, MSD3458). Run the repack command provided by the tool:
The tool requires an instruction configuration file (often a text file or .cfg ) that tells it the exact order, offset addresses, and memory allocations for each partition. Ensure the modified file sizes do not exceed the maximum allocated space defined in this configuration. Step 3: Execute the Repack Command In the GUI, simply click the button.
Press and hold the physical on the TV or device casing. While holding the button, plug the power cord back in.
