Really?

already set to developer mode

• If not done already, enable Settings - System - Advanced - Developer options - Android debugging

@AnotherElk

• Enter the adb devices command to display an ID of the phone to make sure that ADB works with the connected phone (upon first usage the phone should ask you to confirm this access from the computer, there you should also be able to select that the phone remembers that decision, if you want).
