On the phone:
Have you enabled Developer Mode? All the steps are given in the tutorial. Don't skip any of those steps.
Have you enabled USB debugging within the Developer Tools menu in settings (this menu doesn't appear unless you've enabled Developer Mode)
Do you have a good and securely connected USB cable? or change the cable and test it one more time.
no targeted device
I think your are using same phone for app development and internet connection. Without internet connection, the device connected through USB cable listed in android studio. You can select the device and download the app.
Better use separate devices for internet connection and app downloading.
