Hi,

Flying P4P for a year now.

Recently when plugging in the battery and turning the aircraft ON, the motors start beeping and the aircraft lights won't turn on at all.
Tried everything from updating Go app on android to updating controller firmware.
In the end I tried to update the aircraft's firmware through DJI Assistant 2, and while updating the bar gets stuck at 28% and throws as error "battery update failed". What could possibly be the reason?
The bird never crashed in her lifetime. I only have one battery.

Hi, we're sorry to know about this situation. May I know if your Rc would still connect to the drone? If yes, would it be possible if you could provide the error message on the application? Would it be possible if you could provide us with a short video about this situation? Please keep us posted on the latest progress. Thank you for continued support.

Hi,
Sorry for the late reply.
Yes the RC connects to the drone. I can only see the video feed but no telemetry. The drone is not arming either.

Hi, thanks for the update. Have you tried to uninstall and re-install the app then try to re-update the firmware to see if there will be changes? Screenshot or short video would be great if you could provide for further check. Thank you for cooperation.

Hi Tony,

It's been a long time and I haven't been able to solve the problem. Upon updating the firmware, it gives an error "battery update failed"with error code 020003b.

I am having the same problem, p4 pro plus V2.0, I have video but that is it, AC 01.00.5000, App 4.3.14, but my error is 0x020b04 battery update error

Also try 3-battery, has good SD card in AC but does not see it.

I'm having the same problem, and I could not fix it, any solutions?

Hi,

I am having the same issue with my P4PV2, did you ever find a solution / fix ?  I had a battery go bad during flight, the drone fell from 60 ft and broke the landing gear and gimbal. I have replaced all broken parts, now the drone will not startup. I get live video feed but no controls no telemetry.

Hi all,

I'm also having the DJI phantom 4 pro v2 battery error code "0x020b04".
Has anyone found a fix, please?
Any advise is much appreciated.

Thanks
