The camera firmware can be updated over USB using the following procedure:
While holding down the Scroll Wheel, press and release the Power Button to power on the camera in Firmware Update mode. Continue to hold down the Scroll Wheel until the Record LED flashes slowly.
Plug in the USB cable. The camera will appear as a USB drive. This drive is separate from the one where clips are stored, so your footage won’t be visible but is safe and not affected by the firmware update.
Drag the new firmware file (WAVE.BIN) into the fw folder.
Click the Scroll Wheel. The Record LED will begin to flash quickly as the firmware is updated.
Wait for the camera to automatically restart with the new firmware. This should take at most 30 seconds.
v1.4.1 (11 November, 2021)
Fixed a file system bug that could cause the start of recording to be delayed on the first clip after a power cycle, sometimes leading to frame corruption at the start of that clip.
