With my SD card low level formated in the 60D camera, camera settings cleared, October 14 ML files copied to the card, camera in Manual, when I select Update Firmware Ver. 1.1.0, the screen displays "Firmware Update Program Loading..." then the screen goes blank and the red LED on the back right of the camera flashes but nothing else happens. I have to pull the battery to get the camera to respond again. I've tried the October 14th and October 19th and August 22nd versions with the same result. I low level format between different version attempts. I've tried two SanDisk Extreme 32GB cards and one SanDisk Extreme 16GB card.
