What said the BEA
The BEA gave few informations in this may 27 report but one message :
„ the airplane climbed to 38,000 ft,
„ the stall warning was triggered and the airplane stalled,
„ the inputs made by the PF were mainly nose-up,
„ the descent lasted 3 min 30, during which the airplane remained stalled. The angle of attack increased and remained above 35 degrees,
„ the engines were operating and always responded to crew commands.
Everyone understand that the PF didn't cope with a stall warning.
This is the only thing that said the BEA. Everything else is speculation.
