This process is only possible using a downgrade, which can be a fairly difficult operation to complete (Apple authenticates all new software installs using their own servers).There are a few reasons for this, one of which is that if you’re making a warranty claim it’s possible for Apple to tell that your device was jailbroken once some evidence of the jailbreak has been copied back to the freshly restored phone.If you’re not making warranty claims, you still might want to hold off creating a backup. That’s not to say things don’t go wrong, and it might surprise you to learn there’s actually a “right way” to go about doing this.Here’s how to remove your jailbreak and restore stock i OS to your i Phone, i Pad or i Pod Touch.
