How to unlock a nexus 7 tablet after it has updated?

My tablet has updated and I am unable to unlock my tablet because it will not let me use my password, my previous password was three emoticons [ :-DB-) ], now I have typed them in and my device refuses to unlock. I have tried my google account password which has also failed to unlock the tablet, the original booklet has been lost to time, and I do not know what to do next.

Welcome to the forums. Have you tried going to Android Device Manager on a PC and clicking the lock button? That should allow a change password. See if that works.
