Sorry, I thought I saw you get the factory reset sequence over at dpreview. I believe the generic reset is: shutter speed and aperture to A, power on, hold down Menu/Set and right keypad (which is WB on the LX100), turn power off. When prompted, you can now press right/WB twice to exit service mode and do the factory reset. If you have a camera with European settings, you can wander around the menus to adjust/remove limits on video recording times, etc., which exist to avoid the higher import duty on devices classed as video recorders rather than cameras.
