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
Well the trick here is that after you upgrade the firmware, you need to power down the 31AP and power up the 31AP again without the USB connected... just power it up without any connections for a few seconds and then check the version.

It seems that 31AP needs to be booted normally once after the upgrade to show the correct version.
