The camera can only be factory reset in the creative ie (M, Av, Tv & P) modes. Full Auto and other Basic Zone settings do not show the whole menu system.
Yes, both removed with same "Busy". I bought this camera and then purchased an EF 100mm f2.8 Macro lens. I could not get it to work and spent months taking classes, asking for help and still no luck. Finally found out the lens was defective, an internal switch was broken, but by this time I had probably pressed every button on the camera at least 3 times and it was so messed up, I couldn't even take a photo with the regular lens. So, I've bought a new Macro lens and before I even put it on, I would like to reset the camera so I could at least start out correctly. Thank you for your help.
If you can't take a picture with your kit lens or any lens attached. It sounds like your camera is defective and needs repair or replacement.
