If you've forgotten the pattern used to lock your Android phone, we already created a guide @ https://www.hovatek.com/forum/thread-259.html detailing several methods you could use to regain access to your phone. The fastest fix is to do a factory reset in recovery mode. The downside of this method is that you'll lose all user data like installed apps, contacts, SMS and files saved to the phone storage (SD card shouldn't be affected).
