I would like to know if the questions that are "off-topic" or "not a real question" can possibly be reopened by re-editing to change the title and question so far. Take a look at my question I've made here. As you can see, the old question referred to if RSS can be created using LibGDX and I replaced with a new question that tells the problem about the sample RSS Android project not working. Is it possible that if I change the topic and question, votes will up back from -1 to 0 and the question voted open?
The question you essentially seem to be asking is
In that particularly narrow case, and provided that there are no answers or other contributions of value you would invalidate by changing your question, I do not have a problem with it.
Once you've completed your good question, flag it for moderator attention and clearly explain the situation to them. They might then decide to reopen it. (Or they may refuse, if it's still a poor question). This is no guarantee however that you will have the downvotes reversed. Your new question will have to be of significant quality for that to happen.
In general however (even as a question-banned user) you should not completely change your question. Questions should be improved. And if you have a different question, you should ask a new question once you're allowed to. However, given this particular scenario, an exception could possibly be made.
(Note: at the time I did this answer it wasn't known that you were question banned.)
Do not morph your question - that is a guaranteed way to annoy prospective answerers very quickly. If you have a new question then start a new question. Don't change an old question into a completely different new question.
By all means try and tidy up your closed question - once you do flag it for moderator attention and explain the change you have made (but don't waste the mod's time, make sure your changes are good). Keep in mind that they may still dismiss your flag - tidying up a question is no guarantee of it getting reopened. Alternatively you can vote to reopen if you have sufficient privileges, but there is also no guarantee with that approach either.
The easiest thing to do is review your question several times before posting it. If you were looking to answer your question, what would you want to see included in it, how would you expect it to be formatted?
