A hard reset, also known as a factory reset or master reset, is the restoration of a device to the state it was in when it left the factory.
All settings, applications and data added by the user are removed.
The term is often heard in reference to smartphones and tablets but laptop and desktop computers, as well as most other electronic devices, can usually be restored to factory conditions.
1. Lets get started, press and hold power button to turn off your device.
2. Second thing we have to do press and hold the Volume down key + Power key with your hand.
3. When LG logo will appear on screen release both buttons.

5. Now use your volume buttons to move highlighted to wipe data/factory reset area and confirm with power button.
6. And this is it! Now you know how to perform hard reset on your device.
Despite the focus on the hardware issues, just like with the factory reset, this process is pretty invasive.
Since hardware and software work hand in hand, the action will still erase all the data stored on your smartphone. Apps will also be uninstalled and settings will once again require a detailed restore and personalization.
