The Air Caraïbe and the Qantas flights tried to reset their master flight computer in the hope to regain the normal law for the rest of the flight (Qantas was advised by the ground maintenance/technical center).
In the Qantas flight episode the a/c left normal law only when PRIM 1 was reset after the crew turned it off and PRIM 2 became master.
Actually the crew was trying to end the uncommanded pitch down events that maybe were happening because the a/c didn't change to alternate law as it should.
