Forgot unlock pattern
Hi Barbara. If you remember the Google account you used in your tablet, you can bypass the unlock pattern. After a few wrong attempts, an option should appear on the bottom of the screen asking you to enter your Google account username and password. Once you've entered this, your phone will be unlocked.
In case you forgot your Google account log-in, your only option would be to do a hard reset. This process will delete all your phone's content (except SD card contents). Please watch the video from the link below. It's actually for the MID 7012 but the process should be the same. Let me know how it goes. Good luck!
