Fix root-detection

Please go to Android settings, developer options and set the following options as in screenshot:

- Check 'USB Debugging' (should be on already).

- Uncheck 'Always prompt when connecting to USB'

- Check 'Allow ADB debugging in charge only mode'

 

This workaround is based on using WiFi debugging (tested on LG V40 and LG V35), and requires that both your PC and Android device be connected to your Wireless router.

 

1) Plug Android device to your PC using USB and run this command on PC:

adb tcpip 555

 

2) Unplug and connect to Android device:

adb connect ip:5555

 

3) Replace ip by current IP of your device, for example adb connect 192.168.0.101:5555

 

4) Run 3C Companion app on your PC to configure your Android device.

 

5) You can now turn off your PC (or not).

 

Do not disconnect manually (running adb disconnect) as it may break the configuration.

 

SECURITY CONSIDERATIONS: Once WiFi debugging is on, someone on the same WiFi network as your device might be able to access your device without your knowledge. He/she could install apps without you knowing. On Android 8+, he/she will unlikely be able to access your apps' internal data, and on Android 11+, it won't be able to access any app's internal or external data.
