How to Manually Reset a LG Optimus
Over time, the LG Optimus smart phone can start to perform slowly, and a hard rest may be the only way to get it to work properly. There are two main ways to hard reset this device, but you must be aware of the fact that a hard reset will result in all of your information being erased in the process. While it is often best to hard reset an LG Optimus cell phone using the on-screen menus, you can also do it using a battery-removal method if the phone is not able to function properly.
Software Hard Reset
Locate the menu button and press it to bring up the menu options for the hard reset. The hard reset will clear the cache and will often make your LG Optimus phone run smoother.
Press the "Settings" icon on the menu and continue to the next screen and press the "Privacy" icon. This will bring you to the menu for the hard reset through the operating system, which will only be possible if the phone is currently on and working properly.
Press "Factory Data Reset." This will bring you into the final menu to hard reset your LG Optimus phone.
Tap "Reset Phone" and wait for the phone to turn off and then back on again where you will have a fresh install from the hard reset. Customize and set the phone how you would like it as if it was brand new.
Battery Removal Hard Reset
Turn the cell phone off using the power button. This will allow you to perform a hard reset during startup. Wait for the phone to switch off before moving to the next step.
Carefully remove the back cover of the phone to access the battery. Pull the battery out and re-insert it after a few seconds to reset the phone. Replace the battery cover after you have done this step.
Hold the "Home" and volume down buttons simultaneously while also pressing and holding the power button until the phone turns on and the hard reset directions appear. You will need to use both hands to accomplish this operation.
Follow the hard reset menu directions to perform that particular action and restart the phone after it has been reset. Restart the process with a battery removal if you do not succeed your first try.
