Looks like the pilots did everything right initially, but then discovered they couldn't manually trim up, presumably due to air loads. With no other options, they re-enabled electric trim and trimmed up, but didn't trim up enough, and left electric trim enabled. 5 seconds later, MCAS kicked in again, and at the high airspeed they'd reached (365 knots before the dive started - VMO is 340), there was no recovery possible.
