Complete Firmware Update Instructions
You must use an SD-Card reader to perform this operation. Do not attempt to do this directly on the dash cam.
Download the Update autoexec.ash file. This is a simple text file with the following contents (rm a:autoexec.ash
firmfl prog d:firmware.bin >> d:flashlog.txt
rm d:autoexec.ash
rm d:firmware.bin
). This file has the necessary commands to extract the existing firmware from the dash cam.
Download the desired firmware from the section below.
Rename the downloaded firmware file to firmware.bin
Copy the autoexec.ash and firmware.bin files to SD-card using a card reader.
Insert the card into the dash cam and turn it on.
Wait a minute for the process to complete (the whole process takes about 10 seconds).
Turn off the device
Use your dash cam with the latest firmware.
If the above does not work, you may need to try a different firmware name such as vfirmware.bin or yamaha.bin or texet.bin (rename the .bin file and change firmware.bin name within the autoexec.ash file)
