[q] zte zmax pro frp bypass?

So I bought a ZTE ZMAX PRO from ebay but the guy didn't mention he still had his google account linked. So when I boot up the phone I get welcomed by the FRP screen. I text the guy and tell him all the problems but he doesn't reply unfortunately. I've tried almost every possible way to bypass the FRP screen but nothing works. I wanted to know what other ways are available so I am able to actually use this phone.
