I have an old iPhone 4 I want to erase and start using it completely clean. Do not want to restore because it will be used by someone else.
The problem is that I do not like to install iOS 8, as the phone is quite old and not working too fast with iOS 7.
Is it possible to do a clean install without installing the latest version of iOS?
I have a couple of days looking for information, but all you encounter aims to restore from a backup.
