Turn off the dash cam and remove the Micro SD card from the device. Copy/paste or drag/drop the latest version of the firmware you downloaded from above into the root directory of the Micro SD card folder on your computer.
DO NOT place it in a subfolder on the Micro SD card.
Insert the Micro SD card with the updated firmware into the Dashcam when the Dashcam is powered on.
Once the Dashcam recognizes the Micro SD card a dialog box will pop up asking if you want to update the system. Tap OK, and the system will begin to update automatically.
DO NOT power off or unplug your Dashcam while updating the firmware. Otherwise, this will cause damage to the operating system.
