Then reconnect the USB to the computer, run the upgrade program, open the port connect the usb wire to the 31AP and then Power the 31AP through external BEC. Once you get "connect sucess" check for the version.
I have tried this, and now it worked

Actually I upgraded 2 units.
First one inside the plane and second just taken out from the box.

The second one I connected with all pins from USB to 31AP(even the + lead)
Upgraded 2 times, disconnected the plug, closed the port, exit the program.
Did not disconnect USB. Then connected 31AP from USB again for 1 minute, then disconnect.
Opened the program, open the port, connected 31AP, and checked version.
FY-31,Version Number:1.20

Thanx for your help
