Encountering issues where your Android device is not recognized by ADB can be frustrating, especially when it was functioning correctly before. This guide will walk you through practical solutions to resolve this issue, specifically for users on Windows 7 using a Nexus 4 or similar devices.
Understanding the Problem
Often, the issue arises when your device is not properly detected by ADB, even though it is recognized as a multimedia drive by Windows. This can occur despite having the correct drivers installed and the device being in Developer and Debug modes.
Steps to Resolve the Issue
1. Adjust USB Connection Settings
- Navigate to your device’s Developer Options.
- Select USB Configuration and ensure it’s set to PTP (Picture Transfer Protocol).
- If it’s already set to PTP, switch to another option like MTP (Media Transfer Protocol) and then back to PTP.
Switching to PTP mode has been found to resolve recognition issues, as it allows the device to appear as a digital camera, which can sometimes bypass connection problems.
2. Verify ADB Interface
Ensure your device is detected under the “Android Devices” section in Device Manager. If not, you may need to manually update the drivers:
- Open Device Manager and locate your device under “Other devices”.
- Right-click and select Update Driver > Browse my computer for driver software > Let me pick from a list of available drivers.
- Select ADB Composite Interface.
3. Restart ADB
Restarting the ADB server can also help:
- Open Command Prompt in the directory where ADB is located.
- Run the following commands:
adb kill-serveradb start-server
4. Revoke USB Debugging Authorizations
- In Developer Options, select Revoke USB Debugging Authorizations.
- Disconnect and reconnect the USB cable, then allow USB debugging when prompted.
Additional Considerations
If the above steps do not resolve the issue, consider checking the USB cable quality, as longer or lower-quality cables may not support data transfer effectively.
