Found in flaps up mode?
Which would be the requirement for the system in question to be active.
Flaps 0 is not an approved takeoff configuration for the 737, and would have resulted in a configuration warning, but if the flaps were retracted shortly into the climb, that would be one of the prerequisites for the MCAS activation, the others being autopilot off (manual flying); high bank angle, high angle of attack. The single-channel feed AOA probe feed considered by the MCAS logic is susceptible to bad inputs resulting from faulty data, such as that generated by a defective sensor.
