locked out of iphone
I have an extra phone on our plan that my mom uses (she struggles with new technology) -- we upgraded her phone and now seem to be locked out of her old one because no one knows the passcode. She says she never had a passcode on it... But now it has one. Is there a way to reset the phone so we can sell it, as it's no longer in service? I think it's maybe an iPhone 11. I tried what we though COULD be the passcode, and now it just says disabled on the screen when you power on.
