Please download Android SDK tools and start SDK manager then you can install Platform tools. Start a command prompt and type adb shell followed by rm /data/system/gesture.key. You will need to have your phone connected to the computer and USB debugging function enabled. Restart the phone and you can enter any pattern.

If you don't have USB Debugging enabled, you will need to press Volume UP + Home + Power menu and Factory reset your phone.
