Ok, my Phantom 4 is a little over a year old.  I've flown it without issue the entire time including 5 days ago.  Yesterday I took it out fired it up and got a message stating to close to a magnectic field move to another location.  It stated compass needed to be recalibrated as well as the IMU.  I did all of this at 4 different locations including my house, which i do all my updates at so I know there is no issue with any type of interferance, yet I still get the magnetic interfererance AND IMU 1 and 2 calibration failed error.  Please let me know if this has happened to anyone and what if any solution there is.  Thanks so much!!

Sounds a bit of an odd one. I would try a firmware refresh & factory reset using DJI Assistant 2, see if that clears anything.

Just tried a reset with DJI assistant 2, still have all the same errors as before.

Are you on the latest version of DJI Go 4 ?

I've upgraded mine but not had a chance to test yet. Perhaps reinstall DJI Go 4 in case there's some corruption ?

Just to clarify, have you performed any firmware updates or had a hard landing recently? Have you checked your Go app for updates or tried a different mobile device to see whether or not it's a false error message?

My drone has the same IMU Calibration Failed message after million attempts and all these methods.

Same issue here, guess we’ll never see a fix, what’s the deal.

I’m getting exactly the same msgs, no crashes since i purchased it.   Kinda sad things just go south sitting in carry case.
