The one method that works 100% of the time is:

A 16 x 100mm bolt and two nuts will take out even the most stubborn fixed cup. Screw one nut down about four cm, place the end through the fixed cup from the inside and screw on the second nut on the outside. Tighten this nut with a socket whilst holding the bolt head with a spanner. Then continue turning the outside second nut until the cup unscrews.

This method does not depend on engaging the cup's flats, the more pressure you put on the second nut the tighter is the grip on the cup. I have taken out even badly rusted in cups this way. But some proper penetrating oil or diesel soaking over 24 hours will greatly assist the cup's removal.
