Why does my iPhone say Activation Required? It started doing this out of nowhere. I try to unlock it and it goes to Activation Lock. It says "This iPhone is linked to an Apple ID. Enter the Apple ID and password that were used to set up this iPhone."
In the "Activation Help" link it goes to a page:
A password is required to activate this device because its owner has used Find My iPhone to link it to their Apple ID.
I never used Find My iPhone. I also had 2 factor authentication.
Why would my iPhone suddenly brick itself? It doesn't make any sense that an iPhone can just lock itself and render the whole phone useless!
