- 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.

## Contributing | AI/LLM code or NOT ?
- Never, not even auto-complete LLM-powered suggestions. PR is currently closed for some personal reasons.
- Even though this project is NOT vibe-coded or AI/LLM-assisted, another dependencies that the project heavily rely on (APKEditor, coreutils, etc) may contains AI/LLM-generated code or assisted by AI/LLM. While I'm straightly disagree it, theres no escape for that in big 2026 (and also in few next years) so we have to accept the truth that some of dependencies the project relies on can contains AI/LLM code, but that doesn't mean I will code or put AI/LLM-assisted (or generated) code in this project at all.
- Remember : Project may rely on dependencies that can contains AI/LLM code, but is written by a human and NOT LLM (or so calld Generative AI) doesn't mean the project contains AI/LLM code. Every single line of code is done by contributors and me (@cuynu) without any AI/LLM assistance at all.
- If you want to use Generative AI-tools / LLMs for contributing, please fork and do it yourself. We do not accept AI/LLM code in this project at all.
## Project history
<details>
- 05/2023 : MB Bank MOD APK ANDROID project created on Telegram (@mbbmod), providing modified MB Bank APKs since v5.8 with a lot of features such as bypassing accessibility check and show a guide to hide root instead of show rooted screen then close the app.
- 01/2024 : Channel from 2023 is deleted, due to Telegram banning account (@cuynutt)
- 06/2024 : [MB Android Patched] channel created, providing modified MB Bank Flutter APKs and then MB React Native APKs
- 01/2025 : Channel renamed to [MBCP Android] due to MB discontinued version that does not requires CorePatch. MBCP Helper also existed since then.
- 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.
- 07/2025 : MB forced zimperium with v6.4.56, which throw `XPE002` dialog if zimperium is completely destroyed. I fixed it.
- 08/2025 : @fukiame joining to refactor the project source code, make it easier to maintain in the future, also implement good logic.
- 09/2025 : MB forced checksum check, throw `GW934` error if any classes$.dex file or `libapp` aka zimperium aka `libmbshield` is modified. I made a bypass, it works for v6.4.63 up to v6.4.66.
- 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 : 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.
- 02/2026 : MB released `v6.4.85` with enhanced Singalarity eKYC detection (detects `data/adb/modules` and `com.rifsxd.ksunext`), so I created a patch that removed the check.
- 03/2026 : After a long-term pain, Me (author of this project) finally find the right label for myself. This project turned me from just a YouTuber aka tinkerer to a developer who love to write code.
