IMU on Phantom 4 will not completely calibrate. Calibration only progresses to number 2 and then no more. I've tried everything I know but nothing works.
Anyone have any ideas?

To be clear, you have it on a perfectly flat surface, don't touch it during calibration?

I got caught with this.  This is a NEW IMU calibration procedure.  When it gets to step 2 (and dteps 3 -6) you have to re-orientate (turn it on its side) in accordance with the graphic of the phantom shown on screen.  There is a DJI video which shows this.  Or check youtube.

FredAstra is right +1 to Fred

If this does not work make sure to contact dji could be somthing completely different-maybe try calibrating your compass first then try again.

Problem solved! You are correct, it is a new procedure. I didn't realize what the graphic of the Phantom on its side was trying to tell me.  I would make the suggestion to DJI that they add text to the graphic instructing the user to rotate the drone.

It's nice to hear that you have figured it out quickly. And below is the tutorial video of IMU calibration which might be helpful:
