When you have the built in flash up to have pressing the flash button again bring up canon "built in flash function settings" menu or if the flash button is hard to access maybe double hitting the * button?
i sent my camera (60D) to canon to get fixed (hot pixels on sensor) they sent it back and i put in my batery and card that had ml on it and the camera didn't turn on. can a bootable card with ml on it brick a camera that doesnt have the boot disk enabled. my XSi is fine with the card . or did canon just mess up
