Not sure you can eliminate common-sense and airmanship, even in an Airbus
Moving the Flap Lever to 0 with Flaps stuck potentially at 2 leaves you with likely no speed you can fly at below F2 Max, and above F0 Min [GD].
So fly the aircraft (inc safe speed for Flaps), assess / confirm the situation, and at an appropriate time action ECAM. There will likely be more than 1 way to satisfactorily resolve it, and no manual IMHO can cover all situations.
