From the preliminairy report can be found that one of the AOA sensors gave a wrong reading leading to the aircraft trimming nose down, as well as a stickshaker and a multiple of fail flags related to speed and altitude.
Boeing also issued a bulletin where MCAS is blamed.
So there is no final report yet, but MCAS almost certainly was the root cause for the Lion Air crash.
