My camera is 2 weeks old and I installed ML on it a week ago. Have had no issues until today when the camera would turn on for 2 seconds and then give me the ERR 70 message. Tried taking the battery out and restarting and still the same issue. However if I take the SD card out, then the camera turns on and stays on fine. I presume this is an ML issue although I don't know this for sure. I've read the best way to remove ML completely is to format the SD card from within the camera, however obviously I can't do this as my camera doesn't stay on long enough for me to access the menu. Am I missing a trick here? What are my options?
