BT Patcher

BT Patcher is designed to enhance the functionality of the Bluetooth system on Android devices, providing a comprehensive solution for users who require advanced Bluetooth features and security enhancements. This app is particularly focused on the BlueBorne vulnerability, which poses a serious threat to millions of Android devices by exploiting weaknesses in Bluetooth profiles. To counter this, the app implements a specialized quarantine for BlueBorne attacks, effectively disabling vulnerable sections within the Bluetooth stack. This solution is built upon security guidelines outlined in the Android security bulletin.

Requirements and Compatibility

To utilize BT Patcher, your device must be running on Android versions from 4.2.2 to 7.1.2 or Lineage OS 14.1 for Android 7.1.2. A rooted device is necessary as the app requires root permissions and a superuser app to perform the Bluetooth system patch. The app offers a streamlined process to verify the effectiveness of its BlueBorne quarantine feature. By enabling developer mode, users can access debug logs to confirm that BlueBorne attack vectors are effectively intercepted and disabled at the L2CAP connection level.

Additional Features and Functionalities

BT Patcher also supports plugins that extend device capabilities. By enabling the Bluetooth HID Device Profile, you can transform your phone into a genuine Bluetooth mouse and keyboard, facilitating remote control over any Bluetooth-capable computer. Another plugin, ANT+ Enabler, allows activation of built-in ANT+ hardware, which is beneficial for supported devices.

User Guidance and Maintenance

If any issues arise, it is crucial to properly use the "Uninstall" button on the taskbar with root permission to remove the installed patch. This ensures thorough removal from the system folder, as the standard Android uninstall method may not suffice. BT Patcher thus serves as a robust tool for enhancing Bluetooth functionality and security on compatible Android devices.
