Hi

Just took delivery of a new Phantom 4 Pro RTK system today.  The aircraft status LEDs show solid red after the initial power up tone and the fan is on constantly. Is there anything obvious I have missed in the setup? The RC does NOT connect to the aircraft though it appears to be linked, yet it is able to control the camera angle and start recording using the buttons on the RC. I have tried to :

Activated using DJI assistant
Relink RC to aircraft, works but makes no difference
Update aircraft Firmware using the DJI assistant - fails every time at about 86% with error 0x020503
Reset factory defaults
Change SD card
Remove SD card
Tried to reinstall a firmware update, still fails at 86%, tried all the firmware versions (they all download and transmit OK), when the firmware is applying the LEDS do change to yellow flashing.

I will contact the supplier if necessary.

Thanks, Mark

Update - this morning I plugged in the Phantom into another PC, installed DJI assistant, it recognised the aircraft and alerted me that there was an inconsistent (can't be sure about exact word) firmware version and I should update now, so I did and it updated successfully to latest firmware, BUT I still get the red LEDs showing critical error.

Hi,
I have exactly the same error on several Phantom 4 RTK!!!
DJI, please help.
Updating routine brings P4PRTK into a desasterous non working status.

What can we do?
