Investigators had recovered two black boxes from the crash site of the Boeing passenger jet, near the country's capital, Ethiopian state TV reported.
The jet crashed just a few minutes after take-off on 10 March, killing all 157 people on board.
The tragedy raised questions about the safety of the new Boeing 737 MAX 8, as four months ago a plane of the same model operated by Indonesia’s Lion Air crashed into the Java Sea, claiming the lives of at least 189 people.
According to data acquired from the black box of the Indonesian jet, the sensors showed incorrect speed and altitude readings, which could have caused the tragedy, Sputnik reported.
