Your post is confusing and unclear and suggests your understanding of how the drone works is confused too.
Why do you say the drone didn't have GPS?
Your drone didn't need to have it's compass recalibrated, and recalibrating it couldn't fix the problem your compass was warning you about.
DJI's warning message wording is very poor.
You were launching from an unsuitable site and the compass detected magnetic interference which could have caused serious problems.
The solution would have been to avoid launching from a reinforced concrete surface or very close to steel objects.
If you can post the recorded data from the flight, that will help clear up the other issues.
To do that, go to
DJI Flight Log Viewer | Phantom Help
Follow the instructions there to upload your flight record from your phone or tablet.
That will give you a detailed report of the flight.
Come back and post a link to the report it gives you.
Or .. just post the txt file here.
