Dji has released a new firmware update today that is to address the IMU bug.. I am in the process of trying to upgrade right now but it seems to be taking forever.....stuck on constant red stars light and three beeps...one long and two short...anybody else tried this yet...

That sounds like it is done.  da, da da is the finishing tone.  I did two Inspires today.  Are you doing this with the controller on or off?  If you are having issues, I would do it with the controller and App off.  It will do an auto update.  You can look at the .txt file on the SD card root drive to see if you were successful.

Hey yes I got it to work and now I am going through an IMU calibration.  Not sure what IMU is but I am calibrating it

Thx Ed.....I turned off the controller and it seemed to work...says it is updated...can you tell me what IMU stands for

"can you tell me what IMU stands for"

From the DJI Wiki...
Inertial Measurement Unit: includes a 3-axis accelerometer, a 3-axis angular velocity and a barometric altimeter. It is used to recognize attitude.

Or IMU = Inspire Messed Up

I had the same thing, I just turned the aircraft off and on again and it did the update.
