Why an I facing issues after ipod touch update ?

Hello , I was having the same issue some days before. Somehow I managed to fix it . I am telling you the same procedure to fix this issue. To perform some of these steps, you need to be logged in to the computer as an administrator. If you are not sure if you have administrator access,you will have to contact the owner of the computer or the system administrator. You can get rid of most restore errors by following these few basic steps. Update to the latest version of iTunes. Verify that your operating system is up to date. Disconnect other USB devices. Check security settings. Restart your computer. after this if the alert message in iTunes, it may also include one of the error codes. then go to http://support.apple/kb/ts1275. Here click on the link iTunes: Specific update and restore error messages.. I am sure that you will not get any trouble after this.
