🐛 Troubleshooting

ADB Issues

# Restart ADB server
adb kill-server && adb start-server

# Check device authorization
adb devices

# Enable USB debugging on device:
# Settings > Developer Options > USB Debugging

Device Connection

Verify USB debugging is enabled
Accept debugging authorization on device
Check USB cable and connection
Try adb devices to verify device visibility
