Based on my experience with the Usb-can Analyzer, you must select a baud rate of 2,000,000 in the settings. You will know the update is complete when the TX and RX LEDs flash exactly once; at that point, you can use it in the vehicle, ensuring the baud rate in RealDash is also set to 2,000,000 and the CAN speed is set to 500kbps.
