You have to Hard reset or Factory reset your LG Android phone to bring it back to it`s default settings that will going to unlock your phone. But you must backup your files first, because this will going to delete all saved files in your Lg phone.

To Factory reset:

»Press and hold, Home key and Power button simultaneously
»Release the keys, When the recovery mode screen appears,
»Use your Volume down key to scroll down to Wipe Data/Factory Reset, then select it using power key
»Once reset is complete, choose Reboot.
»You`re Done!
