Had something similar happen with a tablet I bought. The thing most people forget about after they do a reset is that you still need the account info that was used when setting up the device. Once you get it started back up, you can add in a new google account and make that the primary one and then delete the original one. I found some videos online that show how to get past the issue. You can try those out before you return the device. Maybe you'll get lucky and they'll work for you. Best of luck!
