IMU Calibration

[Peter Durham]

I haven't used my P4 pro for about a month and when I started it up it asked for an IMU calibration. I have tried everything and it keeps giving me an error 27 code. It won't let me fly either. I have repeated it numerous times with he same error code. Gets to about 90% through phase 1 of 6 before showing this error code. Thanks in advance. Peter

I would hook it up to assistant 2
And refresh firmware something
Could have gone wonky during an update
