Hi, im trying to load firmware 1.00g from my 4g SD card to my Powershot S80. Ive tried using the card tricks auto load method and ive also tried to manually load it. I find the firmware ok but when i select ok it turns the camera off. I have the correct firmware upgrade for my camera. I previously had the CDHK working on this camera before but cleared the SD card by mistake. Is there a setting in the camera i have changed by mistake. Has anyone had similar problems?
