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.!



    Resetting the MobilePro


    Occasionally you may need to reset your NEC MobilePro.
    For instance, you may need to reset after restoring data from
    your host PC, after modifying the MobilePro's configuration,
    when you are unable to power on using the Power button, or
    when the operating system stops responding.
    The NEC MobilePro is equipped with two reset buttons: a
    soft reset button and a full reset button. Read the following
    descriptions to better understand the functions of and the
    differences between the buttons.
    „ Soft Reset Button — The soft reset button allows you to
    restart the NEC MobilePro operating system while
    preserving any saved data. This method is similar to a
    “warm boot” on your host PC.


    „ Full Reset Button — The full reset button restores your
    system to its original shipping configuration, erasing all
    information that you have entered.

    Note: To ensure the safety of your
    information at all times, you should perform
    regular backups of your MobilePro information to
    your host PC
