Will not sync or restore

If You Are Locked Out, Have Forgotten Your Passcode, or Just Need to Restore Your Device

If you have forgotten your Restrictions code, then follow the instructions
below but DO NOT restore any previous backup. If you do then you will
simply be restoring the old Restrictions code you have forgotten. This
same warning applies if you need to restore a clean system.
A Complete Guide to Restore or Recover Your iDevice (if You Forget Your Passcode)
If you need to restore your device or ff you cannot remember the passcode, then you will need to restore your device using the computer with which you last synced it. This allows you to reset your passcode and re-sync the data from the device (or restore from a backup). If you restore on a different computer that was never synced with the device, you will be able to unlock the device for use and remove the passcode, but your data will not be present. Refer to Updating and restoring iPhone, iPad and iPod touch software.
Try restoring the iOS device if backing up and erasing all content and settings doesn't resolve the issue. Using iTunes to restore iOS devices is part of standard isolation troubleshooting. Restoring your device will delete all data and content, including songs, videos, contacts, photos, and calendar information, and will restore all settings to their factory condition.
Before restoring your iOS device, Apple recommends that you either sync with iTunes to transfer any purchases you have made, or back up new data (data acquired after your last sync). If you have movie rentals on the device, see iTunes Store movie rental usage rights in the United States before restoring.
Follow these steps to restore your device:
1. Verify that you are using the latest version of iTunes before attempting to update.
2. Connect your device to your computer.
3. Select your iPhone, iPad, or iPod touch when it appears in iTunes under Devices.
4. Select the Summary tab.
5. Select the Restore option.
6. When prompted to back up your settings before restoring, select the
Back Up option. If you have just backed up the device, it is not necessary
to create another.
7. Select the Restore option when iTunes prompts you (as long as you've backed up,
you should not have to worry about restoring your iOS device).
8. When the restore process has completed, the device restarts and displays the Apple
logo while starting up:

After a restore, the iOS device displays the "Connect to iTunes" screen. For updating
to iOS 5 or later, follow the steps in the iOS Setup Assistant. For earlier versions of
iOS, keep your device connected until the "Connect to iTunes" screen goes away or
you see "iPhone is activated."
9. The final step is to restore your device from a previous backup. If you do not have a
backup to restore or have forgotten your restrictions passcode, then restore as New. If you are restoring to fix a forgotten Restrictions Code or as a New device, then skip Step 9 and restore as New.

The 4th generation iPod is a portable media device that can play music, videos, and display photos.

Occasionally, you may run into issues with the iPod where the player has trouble working.

Restoring your iPod to its factory settings will often correct any software issues the player may have by wiping all of the data off of the iPod, and restoring its software to its original condition.

Restoring your 4th generation iPod can be done in just a few minutes, and requires the help of your computer.

Connect your iPod to your computer using the included USB cable, just as if you were going to sync it to add music or other data.

Launch iTunes if it does not launch automatically, and select your 4th generation iPod from the list of devices on the left side of the screen.

This will launch information about your iPod in the main iTunes window.

Click the "Restore" button in the middle of the iTunes window to begin restoring your 4th generation iPod to its factory settings.

Your computer may ask you to enter an administrative username and password to continue. A progress bar will then appear letting you know the status of the restore.

Wait for the progress bar on the screen to finish and then disconnect your 4th generation iPod.

The iPod is now restored to its factory settings.

You can reattach the iPod to your computer and set it up again, just as you did the first time you used it.

You need to restore the iPod using the latest version of iTunes. This error usually occurs on mac computer's. However, restoring is the same trouble shooting option for both. Below I have posted a step by step on restoring your iPod just in case you need the information :)
How to restore iPod (ARTICLE NUMBER HT1339)
Open iTunes, and then connect your iPod to your computer using the USB or FireWire cable that came with your iPod.

After a few moments, your iPod will appear in the Source panel in iTunes.
Select your iPod in the Source panel and you will see information about your iPod appear in the Summary tab of the main iTunes windows.

Click the Restore button. You will be prompted with one or more restore options that may prompt iTunes to automatically download the latest iPod Software.

The 4 possible restore options are: Restore Option

1: Restore - Restores with same iPod Software version already on iPod. Restore Option

2: Use Same Version - Restores with same iPod Software version already on iPod even though a newer version is available. Restore Option

3: Use Newest Version - Restores with the latest iPod Software available. Restore Option

4: Restore and Update - Restores with the latest iPod Software available.

If you are using a Mac, a message will appear prompting you to enter an administrator’s name and password.

A progress bar will appear on the computer screen indicating that the first stage of the restore process has started.

When this stage is completed, iTunes will present one of two messages on screen with instructions specific to the iPod model you are restoring.
Restore Instruction 1: Disconnect iPod and connect it to iPod Power Adapter (typically applies to older iPod models).


Restore Instruction 2: Leave iPod connected to computer to complete restore (typically applies newer iPod models).

During the stage 2 of the restore process, the iPod will show an Apple logo as well as a progress bar at the bottom of the display. It is critical that the iPod remains connected to the computer or iPod Power adapter during this stage.

Note: The progress bar may be difficult to see since the backlight on the iPod display may be off.

After stage 2 of the restore process is complete and the iPod is connected to the computer, the iTunes Setup Assistant window will appear asking you to name your iPod and choose your syncing preferences similar to when you connected your iPod for the first time.

Error 1416 is very similar to 1418 (you might actually get the latter if you try it again). Try following the directions found here. Does the iPod have any other problems (syncing or anything else)? What changed since the last time you restored it (if you ever did)? Also, try disabling your internet security software.
