If you set a pass code (or pattern) that you cannot remember, please enter the wrong password (10-20 times) until you are prompted to sign in via your google account. Please note, this will only work if you have already setup your google account on the tablet. If you have not set up a Google (or Gmail) account on the tablet, you will have to perform a firmware install, which will revert the tablet back to factory settings
