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. First thing you got to do to start the process is turning off your phone.
2. Power the phone off all the way, press and hold the Volume Down key and press than release the Power key.
3. Wait for LG logo to appear and let go off the buttons.
4. Now there should be a recovery mode menu on your screen.
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! You have reached your destination.
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.
