The pilots followed the checklist, but then reenabled the system very soon after. They left the engines at full power during the descent, which made it so they couldn't manually adjust the stabilizer (too strong aerodynamic forces). [1] Sorry about the wiki source, Google is only showing articles from the first 2 months after the accident. The lion air flight, the first one, is an example of the checklist working (and a large reason why the frame wasn't grounded after the first crash, there was evidence that it was avoidable from the day before) .
