How to Bypass Facebook SSL Pinning on Android

Introduction

Bypassing SSL pinning on Facebook is notoriously difficult. Unlike standard Android applications that rely on Java-based network libraries like OkHttp or HttpsURLConnection, Facebook implements its network stack natively using standard C/C++ libraries (such as Folly and Proxygen) and implements custom pinned certificate validation securely within natively compiled shared objects (.so files).

Typical SSL unpinning tools like Xposed’s JustTrustMe, or Frida scripts targeting Java layer APIs often fail completely against Facebook. To successfully intercept Facebook’s network traffic, we must target its compiled native libraries—specifically libcoldstart.so.

Below, you’ll find the comprehensive guide and resources to bypass Facebook SSL Pinning on Android devices by patching libcoldstart.so, based on the official Facebook-SSL-Pinning-Bypass repository.

📱 Requirements

To successfully bypass the SSL pinning using the modified native library, your setup must meet certain criteria:

1. 🔓 Rooted Android phone or Emulator with root access (e.g., LDPlayer 9 / Nox Player).
2. 🛠️ ADB tools required for real devices to push files to the protected /data/data/ directory. Alternatively, you can use MT Manager to directly manage and replace the .so file on the Android device.
3. 🔄 Tools for traffic capture: You need an interception proxy configured to capture Android traffic. Recommended tools include:
   • Mitmproxy
   • Burp Suite
   • HTTP Toolkit
   • Reqable

🔧 Detailed Setup Process

The core concept is to replace Facebook’s native security library with our patched version that skips the SSL pinning checks. Follow these steps carefully:

1. Download the patched file: Ensure you have the corresponding architecture version of our patched libcoldstart.so.
2. Connect to your device: Connect your rooted phone or emulator to your computer via USB debugging and verify connectivity with adb devices.
3. Replace patched libcoldstart.so: The original library is securely located at /data/data/com.facebook.katana/lib-compressed/libcoldstart.so.
4. Use ADB command to push the patched library:

   adb push [YOUR_libcoldstart.so_PATH] /data/data/com.facebook.katana/lib-compressed/libcoldstart.so
   

5. Fix Permissions (Optional but Recommended): Sometimes files pushed via adb need proper permissions to be recognized by the app. You can verify and fix them via adb shell:

   adb shell
   su
   chmod 755 /data/data/com.facebook.katana/lib-compressed/libcoldstart.so
   chown system:system /data/data/com.facebook.katana/lib-compressed/libcoldstart.so
   

6. Force Stop Facebook: Restart the application for the newly loaded library to take effect.
7. Start Intercepting: Route your Android network traffic through your selected packet capture tool’s proxy port and monitor Facebook requests seamlessly!
