Lightweight **AI-free, human-written** open source tool for patching MB Bank (Android) app with Flutter framework (v6.4.0+) for rooted users (or ROMs with bulit-in CorePatch). primarily written in Bash, made possible by @cuynu and community in Vietnam.

- Project is used to almost DEAD, due to MB's measure to modified dex & libraries from the server-side with GW934 error (`getSHFiles`) when logging in. Luckily, I have a way to bypass the [Zimperium check](/mbcp/mbzdefend-fix), that's why the project still alive till nowadays with other patches.
- The GW934 error is known enabled from the server-side (v6.4.64 works since days 0, but return with GW934 error after 11 days), it requires client (MBCP/MBBank) app to sent the SHA256 hash of 3 app libraries `libapp.so` | `libmbshield.so` | `libclosestmadagascar.so` and all of 5 dex files (classes1->5.dex) to the server for comparing hash, and if it doesn't match, the server will prevent the app from logging in with GW934 error (MB has detected that your device is not secure for performing transactions. Please uninstall the App and reinstall it from the app store). The other function (eg: DigitalOTP) that works without logging in still works.
- This project was made to remove or limit annoying features & root detection & accessibility detection that is implemented by the development team of "MB Bank" Android app with additional features such as custom themes ability, device font, etc (see more in patches list). **It's not PoC (Proof of Concept) project at all.**
- [MBCP](https://t.me/mbcposs) are closed source before, and many people don't like it and concern with privacy & security issues
- In order to support community and allow other devs to improve the project, I spend days to rewritten `MBCP` patches in Bash and open source it so you can patch yourself from original app on Linux or Darwin (macOS) environment. All MBCP pre-bulit releases from v6.4.47+ are all bulit with this open source project with the commit ID at the end of the file name.

> This project contains some proprietary code extracted from MB's app that has been modified to bypass something in the app, but the modified proprietary code is completely public and open source, it will be used for some patches.
- Under `mbsig` directory, it contains original signature from original MB's app, which is necessary to make app works after patching process because the app doesn't work with different APK signature.
- Everything including that listed above code are all licensed under MIT license, it can be considered as reverse engineered code :>
- Short answer : PRs are welcome. Just no Generative AI at all, all the code and assets (except from MB itself) must be made/written by yourself with no assistance from Generative AI.
- Long answer : PRs are welcome, but you are NOT allowed to use any AI-tools for creating PRs with AI-generated/AI-assisted code to this project, even if it's manually reviewed by human. please use your brain and search engine & read documentation for that !
- Even though this project is NOT AI-powered or assisted, another dependencies that the project heavily rely on (APKEditor, coreutils, etc) may have been filled up with AI-generated code or assisted by AI. While I'm straightly disagree it, theres no escape for that in big 2025 (and also in few next years) so we have to live with that AI-generated & AI-assisted code inside the dependencies, but that doesn't mean I will code or allows AI-generated & AI-assisted code in this project at all.
- Remember : Projects that rely on dependencies that is already filled up with AI-generated & AI-assisted code or bulit on top of it but written by human and NOT Generative AI doesn't means the project is AI-powered or AI-generated project.
- 05/2023 : MB Bank MOD APK ANDROID project created on Telegram (@mbbmod), providing modified MB Bank APKs since v5.8 with lots of features such as bypassing accessibility check and show a guide to hide root instead of show rooted screen then close the app.
- 05/2025 : Project is rewritten from closed source (mostly with MT Manager) to open source with `bash` programming language, reduce the trust issues with closed source app before, also allow anyone to patch it manually.
- 06/2025 : [Hide VTAP root detection activity & dialog] patch was added, enables the ability to use the MBCP app with superuser (root permission) enabled.
- 09/2025 : Original project repository is deleted due to contain Gemini (AI-generated) code `platform-tools.sh` (created with stupid behaviour, anything except that is 100% AI-free) then it has been recreated just right after that and cherry-picked commits from the old project repository, that's why you see older commits with merge conflicts; The project is completely AI-free since 09/2025.
- 10/2025 : MB discontinued `v6.4.66`, the last version with almost all patches working (except `bypass_accessibility_applist`) with `GW525` error when logging in
- 11/2025 : After multiple times lying myself and always said that I'm not a developer, **I claim myself as a MBCP developer** and still having skill issues, but atleast, I made this project, and solved the issues that MB's development team created to the MB Bank app by writing code to bypass them.
- 11/2025 (2) : MB released `v6.4.74` with AI-crap button that replaces legacy search button. I created a patch that force replace it back to old search icon.
