Hard Reset for LG Optimus Black P970
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. Then press volume down button and power button and hold them untill next step.
3. When you will see LG logo on your screen you can release those buttons.
4. Now there should be a recovery mode menu on your screen.
5. Using the volume buttons choose between the option and confirm with 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.
