Hello, I recently sent in my phantom 4 pro 2.0 for repair, I have just received it back but can't get the phantom 4 pro plus 2.0 controller to link to it. I tried both methods mentioned on YouTube . When I press c1 and c2 and record on controller at same time I sometimes get a long beep and 2 short beeps and sometimes get no beeps but the controller light always stays solid red and does not blink blue . When I click "remote controller linking" in the app on the pro plus 2.0 controller it says "confirm frequency settings" I click ok and nothing happens. Pressing the linking button on the drone with a pen makes the solid red light flash red so that bit seems ok. The problem seems to be with the controller.

Hi SkyBluP, sorry for the difficulties on linking. Firstly, please double-check whether the firmware of the RC and the aircraft are consistent.
If the RC made a long beep and 2 short beeps after you initiate the link, please press the Pause Button, wait 3 seconds, then link again with the combination buttons.
Or restart the RC, wait for 10 seconds, then link again.

Hello, thank you for the quick reply.

I have installed DJI assistant app and connected the phantom 4 pro+ 2.0 to my pc and it tells me that the firmware on the drone is v01.00.5200

when I connect the controller to wifi it tells me there is a new firmware update called v01.00.5200 (isnt this just the name of a firmware for the actual drone not the controller?) I click download it on the app and it downloads it and then after download it gets to about 5% and fails with a msg saying "update failed. collect error info and to report to DJI Support?"

when I press no it then says, "update failed. restart the equipment and try again later. Reason:aircraft disconnected. Reconnect to continue again."

so I guess it doesnt realise i already have that firmware on my drone (I updated to that firmware using dji assistant 2 a while back)

how do I check what the firmware on my controller is? I can see on downloads section on website there is a download for firmware 01.00.04.00

when I go into general settings in dji go 4 and then click 'about' it tells me:

app: 4.3.14
aircraft: Check for updates N/A
Precise Fly Safe Database (App): Check for updates 01.00.01.18
Basic Fly Safe Database: Check for updates 01.00.01.09
Flight Controller SN: N/A
Remote Controller SN: N/A


"If the RC made a long beep and 2 short beeps after you initiate the link, please press the Pause Button, wait 3 seconds, then link again with the combination buttons."

I tried this but every time I retry the combination of buttons all im getting is one long beep and two short beeps. and the light on the controller stays solid red.

edit: I went into the android settings on the controller and clicked on 'Update' It tells me I have version V0.4.4.2 and when I click 'Check for updates' it doesnt seem to find any.

Step 1 turn on controller, tablet, and drone

Step 2 get to the camera view on app even if it says disconnected

Step 3 go to the three dots in top right hand corner, go to controller icon and select rc sync.

Step 4 when u hear beeps press the Amber light in between SD card and usb connector for drone.

Step 5 should be synced

I tried that, it's called 'remote controller linking' in my app not RC sync. And when I click it it says 'confirm frequency settings?' and when I click ok nothing happens. I guess the version of DJI go 4 is slightly different on the pro plus 2.0 controller. It doesn't do what the YouTube videos show.
