there will be a button called home in your camera. if you press it then there will be customized settings with as many options.in that there is a tab called settings when you scroll sideways.if you press for it another set of options appear. in that set of options there will be an option called "initalize" as the last option . if you select that option your camera will be reset to the original factory settings.hope your problem is tackled. have a nice day
