    3. Locate the extracted .BIN file and copy it to the root (top level i.e. outside of any folder) of a formatted SD card
    4. Fully charge your battery (firmware will not update at fewer than 3 bars)
    5. Insert the card into your camera's SD1 slot
    6. Turn the camera power on while pressing the MENU button
    7. Select "Yes"at the firmware prompt
    8. Once the screen displays "Complete", turn off your camera
    9. Power your camera back on and resume normal use
    10. In order to verify that the firmware update was successful, go to the firmware option under the setup (wrench icon) menu tab, and confirm that the indicated firmware version matches that of the update.

    Note that all updates are cumulative, so the latest firmware version includes the contents of all previous versions.

    Troubleshooting Tips

    If you've having trouble updating your camera, check the points below.  In nearly all cases, your issue is covered by one of these:

    • 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 (the .BIN file is the only thing that the camera wants)
    • Check that the .BIN file is in the top level (root directory) of the SD card, outside of the DCIM folder
    • Delete old update files prior to copying a new update over to your card
    • Ensure that the .BIN file has not been renamed and that extension is unchanged (operating systems can do one or both if there are naming conflicts)
    • Check that your battery is fully charged
    • If your camera has two SD slots, the card with the update must be placed in SD1
