Viofo A139 Firmware

Firmware updates for Viofo A139 2 and 3-channel dash camera.

Caution!  Incorrectly installing firmware can cause your camera to become inoperable.  Sometimes permanently.  Firmware listed on this site comes directly from the manufacturer.  Install at your own risk and only if you feel confident in doing so.


A139 Update Instructions:

File name MUST be FWA139A.bin.  Firmware will not load if named differently.

1. Download the firmware file
Unzip (if needed) the FWA139A.bin file using available unzip programs, e.g. WinZip or 7-Zip
Copy the FWA139A.bin file directly onto the microSD card root file, not in any folders (card must be in Fat32 format - formatting the card inside the camera will make it Fat32).  Using a card reader is the recommended way to get the file onto the memory card.
Insert the microSD card into the camera and power it on via a 5V/1A power source, e.g. USB wall charger, cigarette lighter car adapter or power bank, it will start upgrade automatically.  Do not use your computers USB ports!
While upgrading, the front REC red LED starts blinking (the light blinks slowly at the beginning, then blinks quickly), when the lights stop blinking, that means the upgrade is finished. The camera will restart and the firmware file will be deleted automatically.
IMPORTANT!!  Now go into the APP menu and manually default your cameras settings.  Do not miss this step!
Once the camera restarts, use a paper clip, or something similar, and press the reset button on the side of the camera.  Press and hold for about 5 seconds.  This will clear the memory buffer.
