I can not update the firmware of my RC.
fimware version is not displayed in Dji Go4: N / A
It is not possible to downgrade the firmware to another.
The fimrware version is not displayed (No available firmware to this device).
Code: 0c42d8b674276a8ef0bb5599cf3bc304_BUC4C16713000755

I tried to factory reset the device with the C1 + C2 keys etc.
The RC is completely inoperative. Previously RC reported No signal.
The aircraft is disconnected.
Please help.

Please insert the cable and connect your phone with RC. Then turn on your RC and enter the app. If the color of the indicator of RC is red, I would recommend you link the RC with drone again. Here is the video for your reference.
