Nota: This method does not work if your LG has the verification Google account lock, for this you must purchase the premium reset to remove with Google FRP bypass.
In this tutorial we explain how to reset your LG GD330 and leave it fully restored to factory settings, the phone will remain as the first day it is purchased, without any information or programs installed.
If you have forgotten the phone security code or lock pattern, if you want to sell or give away your device to another person, or if your mobile phone is very slow and is very loaded with information, they are usually the most common reasons why it makes a hard reset
