Just upgraded the Firmware to V.22.214.171.124. Upgraded DJI GO to latest version. Followed the instructions to upgrade the FC via the APP. Now, when I switch on the RC I get a Solid Red light. I go to RC Control Settings, RC Calibration and press Start. Move all the control sticks, but it never gets to finish. When I switch on the Inspire 1 though the FC light goes green but it wont let me start the FC. This is all inside so not a temperature issue. Can anyone help? Do I need to reload the firmware into the FC using the USB method?
