Can you explain the whole problem?
1. You have 1 L camera that won't update to new firmware?
2. What firmware version is it on?
3. How did you format the SD card that you're trying to load firmware from? Or did you use it as it came out of the package?
Suggestion. Put the SD card into the camera and have it "Clear"/format the card. Put the SD card into your PC and then copy the firmware to the SD card. Put the SD card back into the camera and try flashing it.
- What could be happening is the card is formatted with the wrong file system. (FAT/FAT32/NTFS)
@john volkman, can you share directions from Cuddeback on how to properly format an SD card? I can't find their directions, if they exist.
