iPhone 4 unable to sign in with Apple ID
I just found my old iPhone 4 and am trying to set it up with my Apple ID. I have tried several methods to no avail. First, I reset the phone by powering down, holding the home key, and plugging it into iTunes to reset and update software, selecting "set up as new iphone." I connected to WiFi successfully.
When prompted to enter my Apple ID and password, I did this two different ways: Once, with just the password; and the second time using the password plus the verification code my newer iPhone provided. Neither method worked.
I then tried setting up without an Apple ID, going to settings & entering my password into iCloud, both without and with the verification code. Again, nothing worked.
I know my verification codes are working, as I used one to sign in to this platform just a moment ago.
Are there any other suggested fixes for this? The iPhone 4 was purchased through a provider, though I'm just trying to set it up with WiFi. Thanks.
