FollowTroubleshooting security software issues to resolve this issue. In rare cases, these errors may be a hardware issue. If the errors persist on another computer, the device may need service.Also, check your hosts file to verify that it's not blocking iTunes from communicating with the update server. See iTunes: Advanced iTunes Store troubleshooting--follow steps under the heading Blocked by configuration (Mac OS X / Windows) > Rebuild network information > Mac OS X > The hosts file may also be blocking the iTunes Store. If you have software used to perform unauthorized modifications to the iOS device, uninstall this software prior to editing the hosts file to prevent that software from automatically modifying the hosts file again on restart.

During the restore process, if you encounter Error 21, it means that you are trying to restore custom IPSW using the recovery mode. To fix this issue, you must put your iDevice into DFU mode.DFU or Device Firmware Upgrade mode allows all iDevices to be restored from any state.

When you put your iPhone in recovery mode, it loads iBoot which makes sure that the firmware you are trying to restore is greater or equal to the current firmware.To fix iTunes error 21, you must put your iDevice into DFU mode using the following instructions:Connect your iDevice to your PC or Mac via USB cable and launch iTunes.Hold down the Home+Power button for 10 seconds.After 10 seconds, release the Power button but keep holding the Home button until iTunes detect your iPhone in recovery mode.Once your iDevice is in DFU mode, you should see nothing on its screen.
