how do you restore the phone and instal iOS
I factory reset the iPhone 6 plus. It allows me to pick what language, country, wi-fi network, then it sends me to a screen that says activation error. "Activation could not be completed.Please restore the phone and install the latest version of iOS and attempt activation again. If the problem persists, please contact customer support." HELP...what is the steps that I need to take to fix this?
iPhone 6 Plus, iOS 12
