With 1.76 having all the hacks recently buying a console on 1.76 can sometimes result in an unactivated psn account meaning your browser won't work. So basically this guide will allow you to enabled the web-browser of a PS4 if it denies you access. This is PERMANENT and requires NO activated PSN account. Originally there was no public or easy fix for this kind of thing until now, I am not writing a tutorial step-by-step since I thought a visual guide...
Enable PS4 web-browser on 1.76 with deactivated/no PSN account.
