Use a memory card (recommend 16GB-128GB memory card) formatted by camera or on the computer to FAT32.
Copy the attached FWT130A file to the root of the card. （Parallel to the DCIM folder）
Power the camera and the REC will flash rapidly when it is updating,
The bin file will be automatically deleted after the update
Note: if you use the short cable and power by PC, the cam will enter card reader mode after the update.
EthcamTxFWis for the rear camera firmware update, you can ignore it if you do not want to update the rear camera, in case you do, just download it and do similar procedures as the front camera update,(make sure the rear cam is plugged this time,)
