Why iTunes Error 4000 Happens

iTunes error 4000 is one of the many errors that you would see during your iTunes journey. This error is related to your device’s update. The following are some of the reasons why you are seeing this issue on your machine.

Reason 1. Obsolete iTunes Version

One of the major reasons why you face issues with iTunes is that you are using a really old version of the app. iTunes often gets new updates, and if you do not update to the latest versions, your version of iTunes remains buggy and causes many issues.

Reason 2. Old Operating System Version

Like iTunes, an old version of your computer’s operating system can also cause many issues with the iTunes app. This is because iTunes relies on your machine’s OS to supply you with features. If you are using an old version of Windows or macOS on your computer, that may be why iTunes throws error 4000 on your screen.

Reason 3. Your iPhone is Locked

When you are updating your iPhone using iTunes, your iPhone must be unlocked. If your phone is locked, or you locked it while it was being updated, that can cause iTunes to display an error 4000 because it cannot finish the update process.

The following are some of the methods to get around iTunes error 4000.
