My new gimbal has arrived today a DYS Marcia 3. It has a SimpleBGC 8-bit Controller with the extension board for the 3rd axis. I have downloaded the latest version of the GUI, the SimpleBGC_GUI_2_40b7 but didn't work because my board had the 2.30 version. So I have upgraded the firmware using Xloader but when Xloader finished the upgrade the program displayed "Failed to upgrade"

I have entered in the SimpleBGC and I could connect to my gimbal and the firmware field display 2.40, is really upgraded or I have to upgrade the board again?

Thanks in advance
