I am in the process of calibrating my camera.  I can not get past the 3 tutoria screens because it is directing to "reboot the aircraf".
My firmware is up to date.
I have powered off the aircraft and back on.  I have disconnected the USB cable.
These processes is all I know.  What other process is there to REBOOT the aircraft?

Hi, thanks for reaching DJI Forum. We do apologize for the troubles. Reboot and powering off the aircraft is only the same. If you can't get past the 3 tutorial screens, kindly uninstall the DJI Assistant 2 and reinstall it. Have you tried to change different cables? We're here to help you. Thank you.

1) ensured that latest firmware up to date (V02.00.0700
2) new usb cable
3) unintalled DJI Assist 2
4) RE installed DJI Assist 2
5) powered off the aircraft several times when "reboot aircraft" displayed.
The only thing I have not performed is to replace the battery.
Any other ideas?

Sometimes it matters where you have got your downloads from.   I always use the DJI sight for downloads .
I believe there are several versions of this stuff out there.   Can't say this will help
But you never know.....Good luck

Yes, sir...I downloaded from DJI, always.
I attempted calibration using two separate WIN systems; my desktop and my laptop, with fresh downloads from DJI on each.  Before downloading, I removed DJI Assist 2 from both systems and flushed the Registry  Then reinstalled.
Thinking it's the aircraft, now.
Wondering - is there a factory reset option on the aircraft?  Then reinstall the firmware?

Reboot means to give the drone a kick up the butt and then do it a second time.

Seriously, I think it may be the screen resolution that is causing the problem. When you say you are calibrating the camera, do you mean that you are trying to calibrate the vision sensors?
What is the screen resolution of the monitor that you are using. In most cases, calibrating the vision sensors will work best with a screen resolution of 1920 x 1080 or less.

You need to disable driver signing check when installing Assistant2 and when starting it for the vision sensor calibration.
