I can solve it, and I can say for sure that if you only rotate one edge piece, the whole puzzle will be unsolvable.
Back in grade school, I used to solve people's cubes for them. When I got to the point where it was solved except for the unsolvable part, it would be obvious what had happened. I would show them where they pieces or stickers had been changed and offer to change it back for them.
