Enter wrong pattern until you see `` Forget Pattern ? ''

Enter wrong pattern until you see "Forget Pattern?" button on bottom-right. Tap this button and you'll get pattern reset instructions in your inbox (default email attached with default Google Account will be used). If there's no default Google Account attached with device, you'll need to factory reset your device from recovery mode. To save data in this case, create Nandroid backup of your device and restore using Titanium Backup app.
