I wpould like to downgrade my RC Firmware for my P4P.
How can I do this ?

Install DJI Assistant 2 on your desktop computer.

In addition, you should be able to do it via the Go app as well. While only having the RC turned on and connected to the app, hold the menu button on the top right of the 'equipment' page and the option should populate after 3-5 seconds.
