Hello,
I have a Phantom 4 Pro. I have a GL300F controller that works well.
I have a second GL300F (bought used) that can link to drone, can control it but I can't see video on smartphone.
When I turn on the RC and the GO App, It shows that I am connected to an Inspire 2 even though I do not own an Inspire 2 and no drone is turned on anywhere.
Entering Device (even though it's Inspire 2) I can link RC to Drone via GO App. Problem is tha video feed is not send to phone.
The screen is also presented for the Inspire 2 (as I see a setting for a master and slave remote and I can see options to move landing gear). The RC also does not display any message requiring a firmware upgrade. I Tried a lot of times to reset RC pressing C1+C2+Record+right ISO wheel but it does not reset.
I haven't "advanced" options in RC menu to set RC for Phantom 4 pro.
I'm guessing that the firmware is the issue.
How can I manually get the firmware on the RC?
I cannot upgrade it from the DJI GO App or from the DJI Assistant.

Thank you
