I see, real knowledge comes from practice.
Thank you
In this case, real knowledge comes from reading the guides. Obviously, we cant tell you if your switch is actually patched, and we cant run the exploit on the switch to find out if it isnt in our hands. So those of us who come up with stuff, write guides for stuff, etc, try to put the information needed for you to accomplish the task you are trying to accomplish, such as finding out if your switch is hackable, using current methods.
