Nothing convoluted. You have to prepare the V2 to accept the firmware upgrade. Lot's of good information on the "Please read first forum."

1) Unplug the RJ45 (OBDII) connection and the USB connector from the V2 interface.

2) With the USB cable connected to your laptop, hold down the CTRL key on the V2 interface while you plug in the USB cable to the V2 interface. You should notice that some of the LEDs on the V2 now toggle side to side.

3) Now open the Firmware Utility

4) In the 'Update FlashScan V2:' section of the program click on the '...' button to locate the firmware file

5) Once you have located the file (above step) click on the 'Program' button. Sometimes the numbers do not go all the way - this is not a problem, it still continues in the background.

6) The FlashScan device will reboot on completion and the update is complete.
