Lightweight "open source" tool for patching MB Bank Flutter (Android) app for rooted user, mostly written in Bash, made possible by [Cuynu](https://gitlab.com/cuynu).
- Licensed as MIT License : [View license.](https://gitlab.com/cuynu/mbbpatch/-/blob/mbflutter/LICENSE)
## Introduction
- This project was made to remove or limit annoying features & root detection & accessibility detection that implemented by the development team of "MB Bank" Android app with additional features such as custom themes ability,etc. It's not PoC project.
- [MBCP](https://t.me/mbbpatch) are closed source before, and many people don't like it cuz worry about security & privacy issues.
- In order to support community, we spend days to rewritten `MBCP` patches once again in Bash and open sourced it so you can patch yourself from original app on (Bare metal, not WSL) Linux environment
- Note : MBCP are "MBBank CorePatch" but shorter and `MBCP` or `MBCPApp` are the same thing as `MBCP`.

## Requirements
- Actual Linux environment (not on virtualized environment like WSL) and any compatible distro (Arch Linux based recommended)
- Little knowledge about `bash` commands
- `android-tools` for Arch/Fedora based and `android-sdk-platform-tools` for Debian based
- For macOS, you need `openjdk` `gnu-sed` `wget` `android-platform-tools` installed with brew (both need to be added to PATH first!)
- `git` installed
- `java` or `jdk-openjdk` installed
## Usage
- Go to home directory, then clone repository first
```
cd ~
git clone https://gitlab.com/cuynu/mbbpatch.git
cd ~/mbbpatch/MBCPApp
```
- Since MB Bank are now using split APK (*.apks) since `v5.3 (135)` so you have to convert it to regular APK first
- Grab MB Bank apks from [eMBee APKs](https://t.me/embeeapks) or [Lotus Chat](https://lotuschat.vn/w/+anSH1BbDbAYn54JC9nIC9A) if you don't have access to Telegram and copy it to `~/mbbpatch/MBCPApp/mbapk`
- Run bash `mbcpapp.sh` script
```
cd ~/mbbpatch/MBCPApp
./mbcpapp.sh
```
- Download necessary tools first with `Download tools` function (otherwise other functions are unlikely to work!)
- Convert apks to apk first using `Convert apks to apk` function
- Unpack apk with `Unpack apk` function
- Use `Patch App` function and select the patches you want to apply to unpacked app
- When done, use `Repack APK` function to recompile patched app
- Patched app will be `MBCP_Flutter_SelfPatched.apk` on `~/mbbpatch/MBCPApp/mbcpapp_apk/`
- Install it to your device (requires [MBCP Helper](https://gitlab.com/cuynu/mbcp-helper/-/releases) / [CorePatch](https://github.com/lsposed/corepatch/releases) ) with enabled "Disable digest verify" option.
- Profit :)
