I have the Inspire 2, X5s camera and gimbal and literally everything is updated, both controllers master and slave and the aircraft itself. But now my gimbal is not working whatsoever, when it boots up it does its dance but then just stays forward, the degrees bar on the right side of the screen is greyed out and is stuck at -120. It will not auto calibrate the gimbal, i cant adjust the roll, when i try to reset the gimbal settings it comes up saying gimbal settings reset failed. I can move the fpv camera but literally everything to do with the standard gimbal does not work. any ideas?

May be a good start to check the multi-pin plug and socket, although it does sound like a software issue if it boots OK.
