Acabo de leer en el foro del Cielo que si en los codigos de error te pone un "190D" en la Z es un ban como una casa, incluso confirmado en el telefono de Atencion al Cliente de MS.
"Just got of phone with MS 18004myxbox, went threw several networking checks
ms asked for codes x-z, put me on hold while she checked.
returned stated that code 190D under Z states i have modified my 360
I of course argued that fact, got placed on hold once again. Went threw several more checks, network test, change profile,etc... Same code190D=BAN"
