+# Dump MB Logs 
+
+- Since v6.4.60+, MB hidden the `client.log` under `/data/data/com.mbmobile/cache` or `/data/data/com.mbmobile/app_flutter` even without internet connection. This make debugging even more harder for us. 
+- The only place where logs exists since v6.4.60+ is `/data/data/com.mbmobile/app_flutter/hive_databases` but it's encrypted and cannot be read.
+- Only way for now is force v6.4.59 libraries to current app. 
+
+# [Download from releases](https://git.disroot.org/mbcp/mbtombcp/releases)
+
+## Made module manually
+
+- Grab v6.4.59 apks from [Telegram : eMBee APKs](https://t.me/embeeapks) or [Lotus Chat: MB Bank APKs](https://lotuschat.vn/w/+anSH1BbDbAYn54JC9nIC9A)
+- Unzip it :
+- For arm64 :
+```
+unzip embee_v6.4.59_679_arm64-v8a_armeabi-v7a.apks
+unzip split_config.arm64_v8a.apk
+```
+- Grab `libapp.so` from extracted [split_config.arm64_v8a.apk] to logmb folder, then run 
+```
+./createmodule.sh
+```
+
+For armeabi-v7a
+- Run this command under `logmb` folder
+```
+sed -i 's|arm64|arm|g' customize.sh
+```
