It may be that your tris form a concave quad. (It’s a quad in which one of the verts is “inside” the quad. In other words it has angle > 180 degrees.) If it’s so, tris->quads won’t work.

I’ve had this before and have found that if you move one of the vertices just a small amount you can then convert to quads. That assuming you have the same problem I had in this https://blenderartists.org/forum/viewtopic.php?t=55664&highlight= post.
