    Did you put the props on correctly?

    Calibrate the IMU a couple times while having it sit on a flat surface.
    Calibrate the compass outside away from any metal - after that.

    Did you do advanced IMU calibration in the software? Also check that you have selected the correct model in the software. It should be an "X" not a "+".
    Usually when a quad flips it is because props are on wrong, motor is wired wrong direction or motor is plugged into the wrong port on the flight controller.
    Did you buy this used? Could a previous owner have had the top off? A common mistake when taking the top off is to get it rotated 90 degrees when putting it back on.
    I would suggest strapping the Phantom down so that it cannot flip and testing the props, one at a time. Rev them up and confirm that the prop is pushing air downward.

    Yes it can be done in the house. It is possible that one motor or ESC is bad, not responding correctly. I would suggest a test of each with it strapped down.

    The second configuration should be selected.

    As long as I know everything is working correctly, I lift off aggressively. Sometimes when you lift off slow, one part of the landing gear can drag and tip it over. The Phantom cannot truly level itself until it is in the air.
