Hi,

I have a Phantom 3 Pro and just upgraded:

  1 - Drone Firmware to P3X_FW_V01.11.0020.bin -- I do have a Green light on the front of the Drone (Camera Status Indicator [7 in the manual]) - indicating a successful upgrade and the Text file confirmed it was upgraded.  Afterwards, I removed the P3X_FW_V01.11.0020.bin file from the SD Card.

2 - Drone Control Software:
       * iPad - Version 3.1.42
       * Android - Version 3.1.43

I also pushed the Reset button on the Drone to re-sync with the Remote Control (RC). And tried to re-Calibrate the Drone outdoors (spinning aroung 360 degrees 2X - once with Drone level, and once with it facing down).

Thr RC seems to connect (at least a little) to the Drone -- since I can move the Gimbal Dial [14 in the manual] and move the Gimbal up and down.  

Although, the light on the RC flashes Green / Red rapidly. I'm not sure if this flashing back & forth is normal now (I recall it being a solid Green on the RC when it connected to the Drone before) ?

Main Sticking Point: I am now getting 2 Solid Red Lights + Flashing Yellow lights on the Drone and cannot get a Camera pic nor even begin to connect fully and fly.

1 - Do I need to do any further upgrades to the RC ? (When I upgaded my iPad, that seemed to be doing an upgrade to the RC).

2 - What other Trouble-shooting Steps would be good at this point ?

Thank you kindly,
FlyFar

Hello there. We apologize for the inconvenience and late response. Can you provide the firmware version of the remote controller?

Yes, it could be a controller/AC FW mismatch.  

The two solid red lights are on the front right?  They should be solid red.

The rear lamps are the lamps that are trying to communicate with you.  Rapid flashing yellow lamps in the rear tells you the AC doesn't sense a control signal.  They would behave the same if you started the AC with the controller off.  So I think I'd be sure your controller FW is updated and then try to bind again.  

Good luck

The SE is a little tricky.  Be sure your mobile device is set up so that it can receive both 5.8 ghz wifi and 2.4 ghz wifi.  See if your SE wifi signal shows up in the other band and if that doesn't solve your problem.
