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. For a start take your phone and hold down your power button to shut it down.
2. When your phone is turned off you have to press and hold both Volume down button and power button at the same time.
3. When you will see LG logo on your screen you can release those buttons.
4. Now there should appear this menu:
5. To switch between option use volume keys and to proceed use power button on wipe data/factory reset.
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.
