: The most severe outcome is often due to a power interruption during the update, an incompatible firmware file being uploaded, or a corrupted file. Unfortunately, this can be permanent. A factory reset (pressing the reset button for 10-15 seconds) might work, but if not, the device may require professional repair or replacement.
