Hi,

I have got my Phantom 3 Advanced month ago. Had a small crash first week(broken propeler guard and propeler, drop from <1m), was flying with no any issues. Last week I have decided to do the firmware update to 1.10.90, something I was ignoring since the beggining. Following the procedure from DJI site, update passed successfully. Next day I wanted to make some pictures at the nearly located lake, and when I turned on the aircraft baterry, I got "IMU Initialisation Failed" and "Barometer Error". Calibrating didnt changed anything. Any suggestions?

Version:
App: 3.1.11
Aircraft: 1.10.90
Remote Controller: 1.8.0

Yes maybe one suggestion, downgrade the firmware.
The firmware that you used before the update.

I have 2 times made a firmware update, ones I bought it , and some months later, that was more then a year ago.
If something works, do not change it.
Is my suggestion.

Good luck

Calibrate the IMU....

No need for all of that.

Calibration didn't change anything,
