My brother was given a tablet from his school. It comes with restrictions, so i'm trying to bypass them.
The main problem is about websites. I was able to root the tablet and delete the apks which were installed by the school but still there are some websites I cannot connect. Twitter, facebook, youtube etc. are blocked. I've checked the "20-dns.conf" file but there are no signs of restrictions there.
Any thoughts on from which file these website restrictions come from? It is in the system obviously, but it seems like i am not able to find it. I'd be grateful if you could help me.
