If you want to restore your Motorola phone to factory settings or merely erase your personal data, you can do so in a matter of minutes. Most Motorola phones allows the user to perform a "master clear," which erases all the data you have entered on the phone. Some Motorola phones do not have the "master clear" function, but there is another way you can wipe the data. Make sure that you want to erase everything, because a master clear cannot be undone.
Power on your Motorola phone and hit the "Menu" button.
