MASSIVE FAILURE AFTER UPGRADING TO THE LAST FIRMWARE, PLEASE HELP

[Argentum-Volantes]

Hi, on Tuesday I upgraded my Mavic Pro 2 to the latest version with DJI assistant.After that I had a “system warning “ on my controller. Then the DJI Go app report EMU failure and compas Failure. To this point I tried to run all the calibrations unsuccessfully, I can’t initiate any calibration. In the DJI assistant I refreshed the updates, however the problems persist. I can’t calibrate the sensors through the DJI assistant nor the app....please help me!!! Thanks.

Did you update your remote too?

Did you update your remote too?

Yes

 

[brett8883]

Did you calibrate the remote?

 

[brett8883]

And you mean emu and not IMU right?

 

[Argentum-Volantes]

Did you calibrate the remote?

how?

 

[brett8883]

how?

You can calibrate the remote in Assistant 2 or the DJI Go 4 app. The Go app is probably easier. Its under the remote settings menu in the app. Kinda looks like a tiny boom box but I think its suppose to be a tiny remote but doesn't really hah

And you mean emu and not IMU right?

You are right, my problem is with the IMU AND GYRO

how?

Ok forget the the remote calibration for now, never a bad thing to do though.

And did you calibrate the IMU in the DJI Go 4 App?

 

[brett8883]

NIce! You got one handy for calibrating the IMU in DJI Go 4?

 

[brett8883]

I found one

I can’t , because the diagnostics wouldn’t start. The same for calibrating the compass.

I’m sorry can you translate what all those error messages are please

 

[Argentum-Volantes]

error with acelerometer
error gyroscope
the gimble cant receive data from the main controller

 

[brett8883]

Cool thanks. Your IMU isn’t communicating with your main board. We need to try to jump start it.

Connect your phone to the remote and then turn on your bird and start the remote like normal. In the first screen in the DJI Go app there is a button with three lines on it in the upper right corner. Click that.

Then click academy

And then enter simulator.


Fly around for a minute in the simulator. Then land and exit simulator. Turn off the Mavic and then remove the battery. Reinsert the battery and power back up and see if that does it.

The idea here is that when in the simulator the IMU is bypassed and when you exit the simulator there’s a command sent to turn on the IMU that was turned off when in the simulator.

Last thing will it let you calibrate the gimbal?

Not to be counter productive here but could the OP try going back to the previous version of software and see if the problem persists? Would that not indicate whether the problem was/is with the bird or the software?
