phantom 4 adv+ - af/mf/aperture control not working

Hello ladies and gents.

After a crash in my P4A+ some features stopped working. Cant focus at all. Not in AF mode, not in MF mode. Second thing is that my aperture is fixed at 2.8. When i try to change it, it pops right back to 2.8.

I replaced flex cables, camera lens and camera IMU, but still no luck.  Maybe someone had similar problem.

I would be greatfull for any help with this thing.

Cheers Greg.
