Tons of people are getting this error when trying to upgrade their phone t the new software. Many people are even having their phone stuck in “restoration mode”, essentially meaning you have an expensive brick plugged into your computer
Many people are chalking it up to the servers being busy, however there is a quick fix.
Turn off your firewall > restart > plug your phone back in.
BOOM you have a working iPhone.
Why does this happen? Apple is using more than just their normal servers so your firewall gets concerned and blocks it’s access.
Be sure to turn your firewalls back on after….especially for you pervs out there.
