Phantom 4 Pro AC/RC linking problem

[Danebak]

Hi , all !
Iam encountering problem with my P4P. I had a little crash .. ribbon cable to the camera was damaged ... after replacing it ... everything was ok and working .. all functions tested .. calibrated etc .. everything was ok. After puting all together and tightening ... iam no longer able to link rc to ac.
What i have tryied so far:
Double and triple checked all conections
Linking via DJI GO4
Manual linking
Refreshing FW via DJI Assistant 2 (current version 1.05.600 - fw update remains stuck at 24% everytime)
Downgrading FW via DUMLdore ( it gets stuck at same percentage 24%)

At this point i am not sure if its hw or sw related problem.

After powering up AC acts normaly. Gimbal does its calibration thing. Led sequence RED - Green - Red ... then remains flashing yellow ( gimbal is flashing orange)

I would apreciate every help ... since drone is no longer waranty covered :X

thx and sorry for bad english

Most common problem: If using 300F or E remote make sure rc set to transmit @ 5.8G not 2.4 to link. Can be switched back afterwards if needed. It's done in HD Image Transmission Settings, frequency. Also displays at top of screen Go4 (HD)5.8 or 2.4.

Thanks for reply
I have found what was the problem.
I used screw with wrong lenght on clip which is securing flex cable from mainboard to camera. Which was fatal for capacitor under the heatsing.

after replacing it everything works as before.

its located right under the hole for the screw in heatsing ... near cam conector.
Maybe this will help someone in the future
