I think they would use the RESET OF COMPUTERS procedure from the QRH and were probably in touch with their maintenance through the ACARS. That reset was done 30 minutes after the initial event. 3 hours later ... PRIM1 was also reset, maybe in an attempt to go back to Normal Law.
It is also possible the maintenance was directly in touch with Airbus.
