Does anyone know how to unlock a Samsung Galaxy after too many pattern attempts??

I was fuckin around on someones phone trying to figure out there pattern attempt/password thing that allows you access into the phone… After a certain amount of attempts it locks you out and asks for your gmail account… I entered the correct gmail email and password but it doesnt work… Tried hitting the home button then emergency call repeatedly and that didnt work, also tried entering an email plus the password “null” but that didnt work either…

Phone is a Samsung Galaxy prevail for Boost Mobile
