I had to replace the esc on my P34K. With the old board it would fly but no camera view. The new board has camera view but says weak remote signal and won't fly. I tried to update the firmware on the new board and bricked it. Got another board and it says weak remote signal again. What am I missing? I know a new board requires it to be activated just like it was a new drone. I never get that screen and can't find any info on this model. HELP
