Google added Factory Reset Protection in last year in Android Lollipop. The feature seems pretty awesome in theory. The theory is that if you phone is stolen and someone wipes the data your phone will now be useless to them. If thieves are aware of this feature it will make Android cell phones a less than desired target for theft. The only issue is that this is a major pain for law abiding citizens who just want to save a few hundred dollars on a used phone. What has quickly become pretty common is a phone seller will wipe the data on the phone returning it to stock settings and then ship the phone to the buyer. The excited buyer turns on their phone for the first time to find a message telling them they need the Google account credentials of the last person who owned the phone. This is a major bummer. If it has happened to you in the past there is now a pretty clever way to bypass this. The method outlined in the video by Tom of Rootjunky is very similar to the method he uses with Samsung devices. You will have to follow the entire video. You may have to pause and rewind as things get a little nuts! In the end you will have a usable and clean phone!
