    Same issue for me. Been trying all different approaches including the Nokia suite with no luck; finally connected phone using the original USB cable to a *USB hub* and then to the computer, and it finally worked! Guess it might be a problem of USB driver or USB3 issue.

    Solution: try using a USB hub.

    I guess hard reset before recovery might help.
