Rooted device, modified the hosts file and rebooted but still have access to blocked sites I tried to block Facebook on Chrome by changing the hosts file but to no avail. What could possibly went wrong?


Modifying hosts file does not have any effect


I followed exactly what the op did and rebooted, but I could still have access to Facebook.
Just try adding these three hosts name and replace ip address 127.0.0.1  

    facebook.com  
    www.facebook.com  
    m.facebook.com
    mobile.facebook.com


As I checked when typed facebook.com, the site will be redirected to m.facebook.com, so we won't be able to access.
