Wait, what?
To my knowledge there are two ways to access b+. The first way is through homebrew channel and the other is through the stage builder. For the stage builder method, you have to delete all custom stages and then it will load b+ when you go to the stage builder. There should be instructions on brawlplus.net, I think. Also, if all you want is textures, then you would just need to put only the textures on the sd card and not the other b+ stuff.
