Sometimes your phone becomes unusable due to a number of issues, sometimes you just want to start fresh, and sometimes you just forgot your password, and are locked out. Well there are two ways to confront these issues.Please backup all personal data before proceeding, a factory restore WILL Delete ALL Personal Data and Settings.

You will now be looking at another set of options.Before going further, remember this next step WILL Delete ALL of your personal data and settings. You will now want to choose Factory Data Reset. Confirm and continue. Your phone will now restore back to the original factory settings and restart. You will now need to setup your device, and accounts.
This second option is great if you are unable to gain access to your desktop, or have forgotten your password.
Just like with the first option ALL Personal Data and Settings will be Deleted.

Now you will want to Turn Off your device. Depending on your device either combination of these buttons may work. The most common is to Press and hold the Power button, and the Volume Down Button (some phones will use the power button and volume up), or the Home Button and Volume Down .
