LG G3 factory reset stuck in "Checking info..."

[AC Question]

After a factory reset of my LG G3, it comes up with "Android is updating" and after optimising 30 apps it goes to an LG welcome screen, where you can select a language and go to the next screen which allows you to enter a network. The next screen allows you to copy Google accounts from another phone and if you skip this step it goes into a Blue and white screen saying "Checking info..." and there it sits for hours.
