No WiFi Signal from Spark Controller

Just got the spark yesterday, watched a couple videos and followed the instructions to update the firmware on the Spark and the Controller. After updating the controller it no longer shows an SSID, tried to view on a laptop & phone (Google Pixel XL).

*Phone connects to Spark no problem, everything works great

*Controller connects to spark no problem, I can fly around within line of sight ect no problem

*Controller does not give off a wifi signal so I can not connect my phone to it to rollback the firmware or view the camera while I am using the controller to fly the spark.

I have seen other threads on here and on reddit, there seem to be no fixes. I have reset, reconnected, turned off/on in every possible configuration.

At one point the RC wifi came on and both my computer and phone saw the ssid, when trying to connect with it my phone would say "connecting" and then the wifi signal would dwindle out and then the connection would fail. Phone would keep retrying to connect but was never able to connect.

Loaded the DJI Go 4 app on my wife's phone, a samsung galaxy 8, same thing.

Let me know if there is any way to connect to the Controller via the micro USB port and rollback the firmware, or some other fix for this. I was trying to avoid sending the controller back before I ever got to use it.

Our apologies for the inconvenience.  Kindly put your phone to airplane mode and try to connect to the wifi again. We can only update the firmware of the remote controller using DJI Go 4 app and it is not possible to connect it to DJI Assistant 2 to restore or update the firmware. May I know if you tried to use an OTG cable to connect the samsung galaxy 8 to the remote controller? May I know the current firmware version and DJI Go 4 app that you are using?

Also it seems your mobile doesn't work on dual band WiFi frequency. It only works on 2.4GHz .  Initially during take off SPARK uses 5.8GHz frequency and during long flights it switches to 2.4GHz .You need to change your Wifi mode to FCC from CE .  All your problems will go away.
