Hello all, My freinds p4 wil not calibrate the IMU.  The downgrades and upgrades didn't help. The process starts but never completes any of the steps. It ends in error #13. The values read 0 or .1 and do not change when the drone is spun in the air. Do I need a new control board?

Maybe this will help?

Thank you, but i have watched this one. Still no luck

Chuck, please try to power off the drone and leave it for about half an hour. Restart the drone and calibrate the IMU again, please calibrate it in a fine temperature. See if it helps.

I ended up replacing my Flight controller. I tried everything under the sun and finally thought the IMU's just must be bad.  It works like a champ now.  https://www.ebay.com/i/202015938153?chn=ps

Same problem
No way to fix it and I cannot fly the drone!
