I'm guessing that your situation is not what it looks like. You could have a case where similar pieces are switched, but you can't tell. For example, two blue x-centers could be switched. However, since they are both blue, they seem to be in the correct spot. You could try switching pieces with the same color, like x-centers and +-centers. Doing that might lead to a situation that you are familiar with, allowing you to get the cube into the position you want.
Also, redKB on YouTube made this video
on how to make the cube in a cube pattern. He shows how to do it on a 5x5x5 as well as other cube sizes.
Hope this helps.
