Just noticed this on AV herald, if true it is shocking and may explain some of the crews confusion/actions. My bolding, strongly suggest reading the whole article at:
Crash: Ethiopian B38M near Bishoftu on Mar 10th 2019, impacted terrain after departure

Coverage released on Apr 16th:

On Apr 11th 2019 The Aviation Herald received a full copy of the Flight Operations Manual (FOM), Revision 18B released on Nov 30th 2018, which is currently being used by Ethiopian Airlines (verified in April 2019 to be current). Although Boeing had issued an operator's bulletin on Nov 6th 2018, which was put into Emergency Airworthiness Directive 2018-23-51 dated Nov 7th 2018 requiring the stab trim runaway procedure to be incorporated into the FOM ahead of the sign off of this version of the FOM (the entire document is on file but not available for publishing), there is no trace of such an addition in the entire 699 pages of the FOM.

...
...
It turned out, that only very cursory knowledge about the stab trim runaway procedure exists amongst the flight crew of Ethiopian Airlines even 5 months after the EAD was distributed.
...
...
I may have missed this if it was posted earlier, it is hard to keep up given the volume of posts.
