1. Connect the power cord. Do not pull out the wire, turn off the camera and pull out the memory card.
2. Download the archive and unpack.
3. The unpacked "update" folder, copy to the root of the flash drive (just throw it on the card and not in some folder).
4. Insert the card into the recorder, hold down and hold the rightmost button and turn it on with the long long button, hold both buttons until the message about the update appears and release.
5. We wait 15-20 seconds, as the screen goes blank, turn on the recorder and enjoy the new firmware.
