Firmware update shows 'File not found' — what should I do?
Verify the firmware filename is correct, that it's in the root directory (not a subfolder), and that you've downloaded the right file for your model.
If the display shows File not found during a firmware update, check the following: Verify that the firmware file is named exactly as expected by your piano — do not rename the file after downloading.
Ensure the file is placed in the root directory of the USB drive, not inside any subfolder. Re-download the firmware file directly from the Kawai software updates page to rule out a corrupted download. Double-check that you have downloaded the correct firmware file for your specific piano model.
If the issue persists after trying these steps, contact Kawai support for further assistance.
