For example, if you updated your iPhone 7 to iOS 11.2 beta, and create a backup with iTunes, and then you downgrade to iOS 10.3.3, without doubt, you won’t be able to restore your iDevice with the iOS 11 backup. This may happen because of using different iOS versions on your devices. ITunes could not restore the iPhone can also happen when you try to restore your iDevice with an incompatible backup. The reason why this error shows up because the backup that you have performed earlier wasn’t successful and it created a corrupted file.

However, when trying to restore your iPhone, iPad, or iPod Touch later, you may experience the error mentioned above.


Then, you thought you have performed the backup successfully. When you are making a backup of your iDevice with iTunes, it may happen a couple of errors but didn’t show you any messages.
