Unable to Update
I reset my phone to factory settings. Now i'm trying to turn it on and now it says "Unable to activate, An update is required to activate you iPhone." The button then is just to shutdown. What can I do about the update?

Hey there!
There are some steps for activating your device over at If you can't activate your iPhone – Apple Support.
I'd recommend trying all of these steps, but most notably, try the step where you plug it into your computer and try to update that way.
