Factory Data Reset
From this menu you can reset your phone and sound settings to the factory default settings.

2. Tap Factory data reset.
The Factory data reset screen displays reset information.
3. Tap Reset device, then follow the prompts to perform the reset.

Warning! Performing a Factory data reset will erase all data from your phone and internal SD card, including your
Google account, system and application data and settings, and downloaded applications. It will not
erase current system software, bundled applications, and external SD card files such as music and photos.

If you forget your device's lock pattern, you can reset it using your Google Account credentials. When you enter the wrong unlock pattern too many times, you should see an option at the bottom of the screen that says Forgot Pattern. Touch this option and your device will ask you to sign in using your Google Account credentials. You may also use your backup PIN (if applicable) on this screen.

If you have forgotten your Google Account credentials, visit the Google website to recover them. If you still cannot get your Google Account credentials, contact your wireless carrier for additional options.

General advice: Before you buy a new cell phone or new tablet, please try the following procedure to repair your device in a software way. First charge your battery, backup your important data if possible and in most cases take out SIM and SD card before doing factory reset. It is impossible to recover your data after doing a hard reset, so online backup is always important. For all of your data, a backup should be done on an external device, hard drive, raid system or media. With or without insurance, if your cell phone lost, damaged or stolen at least your invaluable data is backed up in a safe place. If you are about to sell your phone and you want to wipe your personal data, or if your phone affected with virus you have to do a hard reset. In some cases, you can delete the forgotten password or lock pattern from your device as well. All information is for devices with stock based ROMs. If you are using rooted device, always back up your EFS folder first, containing your IMEI info, etc.! Please also note, that a hard reset operation will not unlock your mobile phone's SIM lock or network lock, but it will remove the unlock pattern, remove the user password or PIN password (NOT the SIM card's 4 digit PIN code). Also note that the firmware version will not be affected in any way, it will not be downgraded, it will remain the same you are using and if you have rooted your device, root privileges remain also unaffected.
