I would like to ask if anyone knows how to bypass an internet lock from FRITZBOX7490 (on the Playstation 4), I'm happy if someone can help me
Not at all! But why has a lock been put in place?
The lock has its reason, and you should be.
Oh children… Why should the manufacturer program a bypass function? Then the lock would make no sense.
I think the ban is for a reason.
So accept the limitation and improve yourself.
You just have to call the service and say that you have an unwanted block on the Internet.
