Here are some troubleshooting steps:
- Ensure you downloaded the correct firmware file for your camera (a K-3 II update will not work in a Pentax K-3, for example)
- Ensure that you extracted the .BIN file out of the ZIP that you downloaded (the .BIN file is the only thing that the camera wants)
- Check that the .BIN file is in the top level (root directly) of the SD card, outside of the DCIM folder
- Ensure that the .BIN file has not been renamed
- Check that your battery is fully charged
- If your camera has two SD slots, the card with the update must be placed in SD1
- To begin the update, hold down the menu button at the same time as you power the camera on
