Before you buy a new cell phone or new tablet, please try the following procedure to repair your device. First charge your battery, backup your important data if possible and in most cases take out SIM and SD card before factory reset. It is impossible to recover your data after doing a hard reset, so online backup is always important. For all of your data, a backup should be done on an external device, hard drive, raid system or media. With or without insurance, if your cell phone lost, damaged or stolen at least your invaluable data is backed up in a safe place. If you are about to sell your phone and you want to wipe your personal data, or if your phone affected with virus you have to do a hard reset. In some cases, you can delete the forgotten password or lock pattern from your device as well. All information is for devices with stock based ROMs. If you are using rooted device, always back up your EFS folder first, containing your IMEI info, etc.!

    Don't forget to Backing Up iPod touch
    iTunes creates backups of settings, downloaded apps and data, and other information
    on iPod touch. You can use a backup to restore these items to your iPod touch after a
    software restore or to transfer the information to another iPod touch.

    Creating a Backup
    iTunes creates a backup of iPod touch when you:
    Sync with iTunes
    By default, iTunes syncs iPod touch each time you connect iPod touch to your computer.  iTunes won’t automatically back up an iPod touch that isn’t configured to sync with that computer. You can also sync manually by clicking Sync in iTunes. Note that iTunes creates a backup only once each time iPod touch is connected to your computer, before the first sync that occurs. If you sync again, iTunes doesn’t create another backup.
    Update iPod touch
    iTunes backs up iPod touch before updating iPod touch, even if it isn’t configured to sync with iTunes on that computer.
    Restore iPod touch (if you choose to back up)
    iTunes asks if you want to back up iPod touch before restoring it.
