This is NOT a stand-alone application. This application is an add-on component and should NOT be downloaded by itself. It should ONLY be downloaded through “Rescue + Mobile for Android” on a supported LG device.

Rescue should only be used with a support technician you trust. A technician will give you a six digit pin-code to initiate the support session.
