45.56.67.85 DNS + Disable automatic updates = enough to keep jb console safe?

Wait 5 sec.

Hey, guys. Im using y2jb on 12.6 firmware, disabled automatic firmware update and automatic aplication updates + 45.56.67.85 DNS. Is this enough to keep my console safe from sony or any youtube update?   submitted by   /u/Deadoperator92 [link]   [comments]
