Following a process that Boeing reiterated after the Lion Air crash, the Ethiopian pilots flipped two switches and disconnected the anti-stall system, then tried to regain management. They requested to return to the Addis Ababa airport, however had been persevering with to wrestle getting the airplane to realize altitude.

Then they broke with Boeing process and returned energy to controls together with the anti-stall system, maybe hoping to make use of energy to regulate a tail floor that controls the pitch up or down of a airplane, or perhaps out of sheer desperation.
