rest phone to factory iOS 7.1 now WIFI button is greyed out
My brother in law gave me his Iphone 4 when he got an Iphone 6, we reset the phone to factory with an operating system of iOS 7.12 and now the WIFI button is greyed out. I have tried turning it off and on, holding the button on the front and the on off, and tried resetting network and nothing is working. Any suggestions?
iPhone 4, iOS 7.1.2
