## Introduction 
- [MBCP (MBBank CorePatch)](https://t.me/mbbpatch) are closed source before, and many people don't like it because worry about security & privacy issues. 
- In order to support community and make MBCP open source, We spend days to rewritten whole `MBCPApp` patches in Bash and open it so you can patch it yourself on (Bare metal, not WSL) Linux environment (where we used to patch `MBCP`)

## Requirements
- Actual Linux environment (not on virtualized environment like WSL) and any compatible distro (Arch Linux based recommended)
- Little knowledge about `bash` commands 
- `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) 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 function with unlikely to work!)
- Convert apks to apk first using `Convert apks to apk` function
- Unpack apk with `Unpack apk` function
- Check if MBShield present on unpacked APK with `Check MBShield` function 
(if MBShield present then you have to extract assets from Android device with `Extract assets [ROOT]`)
- After extracted assets (if MBShield present), use `Patch App` function and select the patches you want to apply to unpacked app
- When done, use `Repack APK` function to recompile apk (You must have Android device connected with debugging mode enabled!)
- Output will be `MBCP_Flutter.zip` on `~/mbbpatch/MBCPApp/mbcpapp_apk/` and `mbsig.apk` will be copied to Android internal storage
- Use [MT Manager](https://mt2.cn/), put all files inside `MBCP_Flutter.zip` to `mbsig.apk` and untick `AUTO SIGN`
- Install it to your device (requires [MBCP Helper](https://gitlab.com/cuynu/mbcp-helper/-/releases) / [CorePatch](https://github.com/lsposed/corepatch/releases) ) due to unsigned APK
- Profit :)

## TODO
- fully implement `Bypass signature check` function

## External projects 
MBCPApp Patcher project won't be possible without those external projects !!
