hmm... Should i format my sysnand to be sure?
as i said in other post, the system format dont work and dont demonstrate nothing...when you register a NNID , your console mantain attached to your old NNID unless you create a dummy NNID and try to attach ur banned console
on nintendo technical support said that your NNID continue attached to your console till you take it over another console....format dont eliminate this attach....
Test NNID banned on a new console is only another test to clarify the ban method
greetings
