This occurs when the media library on the device is corrupt and cannot be modified or updated.
Updating to the latest version of iTunes and then restoring should resolve this issue

I try to follow the steps for a factory reset as outlined "everywhere" but then I get an error code of 2001. My Mac has the current iTunes software but I can not get the iPhone 4s to update. I'm in a loop of errors. Help

Error code 2001
The Mac OS X kernel extension "IOUSBFamily" that was bundled with late 2008 / early 2009 MacBooks, as well as the 10.5.6 update, has a bug where it fails to properly recognize an iDevice in DFU Mode. It can be resolved by updating to 10.5.7 (or later), or using a USB hub.
