I just purchased a Canon 60D from a friend. It had been working fine while he had the camera. I bought a battery and an SD card for it. Watched a video on the 60D. Played with the settings and familiarized myself with the menu. I updated the firmware to Ver.1.1.2. Before I played with all of the settings it seemed to be working. I took it on a photo walk after setting things the way I wanted them, and it went haywire. In manual mode it makes a click sound, viewfinder goes black and nothing happens. In auto mode when shudder is pressed the camera starts firing in continuous shooting mode then gives out error message. No image is recorded. Can I set it back to factory settings. Will that help?
