📱 Requirements

Option A: Physical Android Device (Rooted or Non-Rooted)

• Android phone or tablet running a compatible Facebook version
• ADB access (USB debugging enabled, or wireless ADB)
• A traffic interception proxy:
  • Reqable — modern UI, excellent mobile support
  • Proxypin — free, lightweight, no-root option

Option B: Android Emulator (PC)

• Windows/macOS/Linux PC with an Android emulator:
  • Nox Player — enable root access in settings
  • LDPlayer — enable root access in settings
• A MITM proxy tool:
  • Burp Suite — industry-standard web security testing
  • mitmproxy — open-source, scriptable
  • Reqable — cross-platform, modern
  • Proxypin — lightweight alternative

Note: Root or elevated access is required.

🚀 Bypass Procedure

Step 1 — Replace the Original Library

Push the patched libcoldstart.so into Facebook's lib directory using ADB:

adb push /path/to/patched/libcoldstart.so /data/data/com.facebook.katana/lib-compressed/libcoldstart.so

Step 2 — Set Correct Permissions

Ensure the replaced library has the correct permissions so the app can load it:

adb shell chmod 755 /data/data/com.facebook.katana/lib-compressed/libcoldstart.so

Step 3 — Configure Your MITM Proxy

1. Set up your preferred proxy tool and start listening on the designated port.
2. Install and trust the proxy's CA certificate on the Android device or emulator.
3. Configure the device's Wi-Fi proxy settings to route traffic through your proxy.

Step 4 — Force-Stop, Launch & Capture

adb shell am force-stop com.facebook.katana
adb shell monkey -p com.facebook.katana -c android.intent.category.LAUNCHER 1

Open your proxy tool — you should now see Facebook's HTTPS traffic flowing through in cleartext.

Tip: Always force-stop Facebook before relaunching to guarantee the patched library is loaded from disk rather than from a cached process.
