My Lumia 520 had a software problem.l use Windows device recovery tool to restore it.
It download 1.5GB data & start installation progress but it shows OPERATION ENDED WITH FAILURE (This device not correctly signed in)
Plz help me!!
 
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.
