My drone had a crash and I replaced the gimbal, because the flex cables were broken.
Now the drone doesn't want to connect to the controller. All the LEDs come on, the sound is there, the gimbal come on, fan comes on. When I try to connect the rear led flashes fast as it should. I then press the reset button and the LED goes from green to red. It just doesn't want to connect even after I replaced the wi-fi card.
I connected the drone and the controller to my computer and did a factory reset and then reloaded the latest version of software,  but still no success.
What else can I do?
