we will see and come back to this gents, but i do not think so - it was not nose down but up till the stall angle , i think he had some massive drag either by speed brakes / spoilers extended , a reverser unlocked or he had lack of power by the engines. the flaps were put up intentionally as soon as possible to reduce drag and he aimed for minimum clean speed , the words "damn flaps" was either false translation and he meant spoilers or a last desperate word when he realized he is down to a speed he will stall for sure without flaps.
raising flaps immediately after takeoff will result in an crash very close to the airfield or a none event , depending on the mass, crew action , power of the engines and the design how critical the wing is.
i would not blame the fo he grabbed the false lever because i,m sure its not the cause.
