Nandroid takes a backup of everything on your phone memory. Rom, data etc. It takes you back if restored to that exact.point in time.

You should take one before everytime you flash something.

You can only take them after being rooted so yes if you backup your stock Rom once rooted, you can restore it.

It does not backup or restore recovery or hboot so it won't return you to stock for warranty repair. Only then do you need an ruu
