Itunes won't open my ipod

The iPod Touch is a type of iPod that features a touch screen and can function as both a portable media player and as a pocket computer.

It is possible to password protect your iPod Touch so that you will have to enter a password every time you want to unlock the iPod Touch screen.

If you repeatedly enter the incorrect passcode, your iPod Touch will become disabled.
To unlock a disabled iPod Touch, you need to sync your iPod Touch device with iTunes on your computer.

Attach the iPod Touch data cable to the bottom of your iPod Touch device and attach the other end of the data cable to an available USB port on your computer.

Open iTunes on your computer and then select your iPod Touch device from the list of available devices on the left side of the iTouch window.

Click the "Restore" button.

If you have previously backed up your iPod Touch, you can choose to restore the device to the last back up or any saved backup.

If you have never backed up your iPod Touch, this process will restore your iPod Touch's factory settings.

Wait while iTunes syncs with your iPod Touch and restores the device.

iTunes will prompt you when this process is complete.

or
A hard reset restores your iPod Touch to its original factory settings.
This is useful when your iPod Touch is disabled and won't turn on or off, but all your data is erased.

Luckily, you can restore your data with iTunes after you've performed the reset.
Once you've performed the reset, your iPod is wiped clean and iTunes prompts you to restore the settings from your last sync.

Plug the iPod into your computer and wait at least 10 minutes.
This allows the battery to recharge in case it has drained.

This could fix your disabled iPod, if the problem was caused by a dead battery.
Click "OK" if your computer opens a "Connect to iTunes" alert box.

Depending on your version of iTunes, the message may indicate the iPod is in "recovery mode" and you need to restore the device.

ITunes opens and resets your iPod for you.
Unplug the iPod from your computer if you don't see the "Connect to iTunes" alert box.

Make sure the iPod is charged before you attempt the hard reset.
Press and hold both the On/Off/Wake button and the Home button on your iPod.

Keep the buttons pressed.
Wait for the Apple logo to appear, it may take 10 seconds or longer.

When you see it, release the On/Off/Wake button but keep the Home button pressed.
Release the Home button when you see a picture of a USB cable with an arrow pointing to the iTunes logo.

Plug your iPod back into the computer.
The iTunes "recovery mode" message will appear.

Click "OK" to complete the reset.

Unfortunately, the only easy and reliable way to reset the passcode on an iPod touch or other iOS device is to perform a complete restore of the device, which will wipe everything on it. Connecting your iPod touch to your original iTunes library will reset any disabled passcode counter, allowing you to make additional passcode attempts, but it will not bypass the passcode.

The good news, however, is that as long as you have a backup of your iPod touch in iTunes or iCloud, you can restore that backup onto your device after you've erased it, thereby allowing you to basically pick up where you left off. Restoring from backup will recover all of your data and settings except for the device passcode, which you will be prompted to re-enter. You may also need to re-enter some passwords for things like e-mail accounts or Wi-Fi networks as these are secured by the device passcode, and thereby lost if you can't remember your original passcode.

Note that even if you haven't already made a recent backup of your device, you can still make one even with the device locked provided you still have your primary iTunes library available-usually the iTunes library and computer that you originally setup your iPod touch with. To do this, simply plug in your iPod touch, right-click on it in the Devices listing in iTunes, and choose the Back Up option from the context menu that appears.

Restarting your computer is often the solution when your iPod fails to sync with your iTunes music library. But if this fails, there are other troubleshooting steps to take.

Recharge your iPod via a USB cable connected to your computer or AC adapter. b> Click the help menu in iTunes and check for updates. Follow the onscreen prompts to download and install the latest version of the software. Open the new version of iTunes.

Slide your iPod's hold switch to the hold position and then to off. Press and hold the menu and center buttons simultaneously until the Apple logo appears to reset your iPod. Open iTunes on your computer and reconnect your iPod to try to sync it with iTunes. Restart iPod service b> Close iTunes and make sure your iPod is disconnected from the computer. Click the 'start' button. Click 'run' if using Windows XP. Type 'services.msc' in the run box in XP and in the search box in the start menu in Windows 7 and Vista. Press 'enter.' Scroll through the list and double-click on 'iPod service.' Click the 'stop' button and leave the properties window open. Connect your iPod to the computer.

Hi

Some iPods, such as the iPod Touch, include a passcode option as a security feature. The passcode is intended to deter thieves from stealing the device and to discourage any unauthorized use. If you have set up a passcode on your iPod and now have forgotten it, you can bypass the passcode screen. Bypassing the passcode screen requires that the device be fully restored. Restoring the iPod will remove all files from the device. Only files in the iTunes library, or in another place on the computer, can be restored. Once restoration is complete, you can update the iPod.



What you need? USB CABLE

2 Connect the iPod to the computer using the USB cable.

3 Press and hold down both the "Power" and "Home" keys simultaneously for 10 seconds or until the screen goes black. Now release the "Power" key.

4 Release the "Home" key when the message "We have detected an itouch in recovery mode" appears. Confirm that the iPod will be restored.

5 Hit "Back up" to save your iPod settings when prompted.

6 Select the "Restore" option. Allow restoration to begin. Make sure to keep the iPod connected to the computer and iTunes open. Once complete, the Apple logo will display on the iPod screen, and iTunes will notify you when the process is complete.

1 Open iTunes and connect the iPod to the computer using the USB cable.

2 Select your iPod under "Devices" in the left pane.

3 Click the "Summary" tab.

4 Click the "Check for Update" button. The iTunes software will check for any available updates. Follow the additional prompts to confirm and install the updates.

What you do is connect your ipod to your computer open itunes click restore ipod it will then erase all apps, music, movies picture, etc and will also erase your password.

You can bypass that lock by doing the following steps:

2. Turn it OFF
3. Press and hold the POWER and HOME buttons together for EXACTLY 10seconds
4. Release the POWER button but keep holding the HOME button until the computer beeps indicating that a USB device is recognized.
