Performing a Hard Reset on a LG Optimus One
A full reset is sometimes referred to as a hard reset. Perform a full reset when you want to clear all settings, programs and data from RAM.
Caution if you perform a full reset, your LG Optimus One returns to its default settings and looses all information that is not recorded in ROM.
To perform a factory (hard) reset:
- Turn on the phone by pressing and holding Power
+ Home 
+ Down volume key at the same time (for 10 seconds).
- The phone will turn on and perform factory reset immediately.
