Please HELP!.  I recently bought the Spark Flymore combo, flew several times.  Decided to do an IMU Calibration for stability.  System was taking forever.  After letting it sit for 20+ minutes I powered off and restarted drone, controller and phone app.  Tried IMU Calibration again.  Same experience.  Restarted again - but this time the drone wont connect to controller and/or phone app.  Pressing power button on drone does nothing - no 3/6/9 beeps.  Controller eventually beeps and shuts off because it can't find the drone.  Tried to use app to connect to drone but no luck.  Drone powers on/off but sits with front rotors solid red and back rotors flashing fast yellow.
I downloaded JDI Assistant (Mac) and tried to connect.  It sits on the circle screen and never recognizes the divece connected.

What can I do to reset this?

you have to place the aircraft as told in the app. this requies you to place the AC in 90° Angles. Look what it says on the dji go app and try to move it till the lights flash green. You will need to turn it 4 or 6 times.

I'm way past that now.  Need to get basic functions working before I can worry about that.

1-test usb~c adapter problem.
2-press 3 button command to bind.(pause+fn+c1)

Perhaps try a different USB-C port on the MacBook Pro?  As xtok suggested above, verify the USB to USB-C adapter is working properly.  Also might try swapping batteries or removing/reinstalling the current one.
Also, I *think* the sequence of connecting the Spark to Assistant 2 is important.
Here's the video from DJI showing the order of connection/power on:



That's all I can think of at the moment.

Thanks for the advice.  I had already tried the wired connection with 2 different usb-c adapters.  They both work with external hard drives so I don't think that's the problem -  though I wish it was.  I tried your 3-button press and the controller beeped fast & loud with the led flashing green for 3 minutes before quitting.  Drone never changed.  App screen never changed.

Thanks Lee.  I tried a different USB-C adapter and the connection sequence from the video but nothing changed.  To test the USB-C adapter I also plugged in a Seagate drive - it registered fine.  You can see the drive in my Finder but the Spark is not recognized.

Did you set the drone into pairing mode as well

power on spark.

after power on press power and keep for 9 seconds. spark beep.

Thanks Xtok.  I have tried that with no luck.  The power button does nothing except the on/off control.  It won't beep/reset at 3/6/9.

UPDATE - I spoke to tech support who advised me that the drone is 'unresponsive' and needs to be sent in for repair.  So frustrating.   All I wanted to do was calibrate it and fly.  That was 3 days ago.  It could take longer to repair than the length of time I have had it.
