cant log out of an invalid apple id on new phone
i have retreived an old backup by mistake - on it was my old apple id - which is no longer valid - now i'm stuck logged in to icloud with an invalid apple id - cant log off or erase it - cant replace it - email address is old and no longer available - itunes works fine with current valid apple id - but i keep getting pop ups to put password and cant upload correct backup
iPhone 7, iOS 11.2.6
