When using iTunes to restore or update your iOS device, you might get an alert saying something like “The iPhone could not be restored. An unknown error occurred (28)”. After reading this post, you’ll fix iTunes Error 28 and get your device back to full working order.
iTunes Error 28 occurs when there is a hardware glitch during the update or restore process. In order for a successful restoration or update, information is transferred between your device and your computer which creates a successful backup of your data and enables you to install the latest software. Error 28 prevents these things and means your device is not functioning properly.
Error 28 can be caused by several issues, including missing dynamic link library (DLL) files, incompatible drivers for your iOS device, corrupt system files, problems with a virus or spyware program or apps that have been incorrectly installed. The error can cause your computer to perform slowly, other errors to pop up, restricted app access and even the Blue Screen of Death.
