What is iTunes Error 4005 and How to Fix?

Apple’s iPhones, wonderful devices as they may be, are not immune to errors and bugs.

Being the most popular smartphone (as of 2022, it is estimated that there is around one billion iPhone users in the world), sadly doesn’t make it perfect, and iPhone users are already so used to running into issues with their phones from time to time.

A common bug that plague some iPhone users today is known as the iTunes Error 4005.

Here’s what to expect from this infamous iOS issue.

What is iTunes Error 4005 and Why Does It Happen?

The iTunes Error 4005 issue happens whenever you try to update or restore your iPhone using the iTunes software on your computer (note: this can happen on both Windows and MacOS computers).


You’ll see an error message that pops up that states “The iPhone {your iPhone name} could not be restored. An unknown error occurred” followed by the identifying number of the error, which is 4005.

Error 4005 can stem from a list of possible causes.

These range from iOS system errors, a corrupted or incomplete iTunes installation, iCloud’s syncing feature getting disabled, malware, etcetera.
