Normal Human's advice is spot on.
Stack Exchange works best for questions that have a clear, understandable problem that has (the potential for) a single, correct answer.
A question that's going to require a lot of back-and-forth or some hands-on debugging interaction is not a good fit.
One of the tenets of Stack Exchange is that the questions and the answers aren't really for the person who actually asked the question. It's for the people who follow who have exactly (or close to) the same problem. If you're doing a bunch of "try this", "do that", waiting for the results, and then offering new things to try, the only person you're really helping is the person with the original problem, and that wavers awfully close to the definition of a help vampire.
If you really do want to help someone with such an issue (and those of us who answer questions here want to help people, otherwise why are we here?) then perhaps pulling them into a private chat room is a better way to go.
Of course, if you can devise a decent heuristic approach to a problem that a lot of people run into, a canonical community wiki question and answer could be very useful for pointing people to (and as a duplicate target). This question on Android Enthusiasts is a decent example, I think.
