Hi there can anyone help me put new product number on my licence file for my Yuneec typhoon h 480. I have tried and tried but have had no luck can anyone help or do this for me? Many thanks
 
It’s coming up invalid on the license so it’s not letting me put it into my craft and my other license is saying wrong file? Can you help I will pay you
 
1. Download H480GUI.zip.
2. Unzip this file to a directory of your choice.
3. Start H480GUI.exe
4. Click on button "Open license file"

5. Select your old license file (pfx file)
6 You will get the two button to disable/enable NFZ.

The buttons will be active if the drone is connected over USB and sent a serial number. Now you disable NFZ.

There is a description how to connect the drone (in fact it is the same as the old Yuneec GUI is working, except you have to click on connect instaed of auto-connect).
 
The buttons will be active if the drone is connected over USB and sent a serial number. Now you disable NFZ.
Does the serial number originate in the Flight Control Board or does it originate on the Main ESC board?

If it comes from the Flight Control Board, will the serial number from the new Flight Control board be the same as the serial number recognized by the pfx file?
 
It’s the old license and product number but when I done it the way you sent instructionss. It said ok when pressed the disable NFZ?
 
Yes, that is the idea. If you have a valid license (valid for the serial number in the file name) then it is valid for all serial numbers. Thus, you can from now on exchange the flight controller board without losing you license.
The OK is triggered by the success message sent by the flight controller if he accepted the encrypted message. Works now.
