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 Your Pocket PC Phone

    Occasionally you may need to reset your Pocket PC Phone. A normal (or soft) reset of your device clears all active program memory and
    shuts down all active programs. This can be useful when the device is running slower than normal, or a program is not performing properly. A
    soft reset is also necessary after the installation of some programs. If a soft reset is performed when programs are running, unsaved work will
    be lost.

    You can also perform a hard reset (also known as a full reset). A hard reset should be performed only if a normal reset does not solve a
    system problem. After a hard reset, the device is restored to its default settings—the way it was when you first purchased it and turned it
    on. Any programs you installed, data you entered, and settings you customized on the device will be lost. Only Windows Mobile software
    and other pre-installed programs will remain.

    To perform a soft reset

    • Use the stylus to lightly press and hold the RESET button on the left side of your device.
    The device restarts and displays the Today screen.
