Phantom 4 Pro v2.0 previously functioning perfectly, no crashes, no recent upgrades

Upon start all four status LED's on the aircraft are solid red

RC status LED is green, DJI GO 4 shows "connected" and "go fly" but when entering the flight camera screen I am abloe to see a video feed but the status bar says aircraft disconnected


Any advice?

Try relinking RC to aircraft, that has been known to solve similar problems in the past

Update:

Tried re-flashing firmware through iOS and DJI Assistant on PC. Firmware refresh fails on both devices (at 90% on iOS and at 24% on DJI Assistant). On DJI assistant it says "battery error" however this occurs when I try with any of my 3 batteries

Hi Aardvark, thanks for the reply! I have tried re-linking and it doesn't resolve my issue. The status light on the RC is solid green indicating a proper connection

If you have 4 red indicator lights on the phantom its means a hardware issue. I would check the motors first, do they all still operate normally?

Check the battery latch sensor.

I have an older P4P+ and I'm having the same issue except my 2 rear light start off blinking green and turns to solid red in flight.  Controls seem to operate properly.

I don't suppose you ever found an actual answer to this, have you?  I'm having the same exact problem and I have even changed out the RC that came with the drone, to a back up RC.  Linking and everything else works just fine.

You might look at one of the logs - see if you can find something that doesn't seem right.

Same issue for me.  Lose cable connection.   Check ALL your connections.  Some are hidden.  Look carefully.
