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 Treo Device

    Soft Reset

    Performing a soft reset is similar to restarting a computer. If your Treo device is not responding or you’re having trouble synchronizing with your computer, a soft reset may help. All your information is retained when you perform a soft reset.

    1. Remove the battery from your device, and then reinsert it.

    Note: The reset begins when you insert the battery and ends when the Date & Time Preferences screen appears.

    2. Select Done.System Reset

    Replacing the Battery

    Your Treo device comes with a replaceable battery. Be sure to use a battery that is approved
    by Sprint and that is compatible with your device. Failure to use the proper battery may
    result in personal injury or product damage, and it voids your device warranty.

    A system reset, also called a safe or warm reset, can be useful if your device loops or freezes during a soft reset. Performing a system reset allows yo1u to get out of the loop and restores limited functionality to your device in order to uninstall a third-party application thats
    causing the problem. Note that after a system reset, you must perform a soft reset to restore full functionality, including the wireless features, to your device.

    Hard Reset

    A hard reset erases all information and third-party software on your Treo device. Never perform a hard reset without first trying a soft and a system reset. You can restore previously synchronized information the next time you synchronize.

    Note: Your device might not re-establish a Sprint Vision session after a hard reset. To manually establish a new Sprint Vision session, open the Web browser to access a Web site.

    A hard reset can tell you if a problem stems from your Treo device or from an application installed on it. If you do not experience the problem after you perform a hard reset, the
    problem is related to software you installed.

    Important: If you set a password on your device, performing a hard reset reformats your device. This is a more severe form of a hard reset, which removes all your information, and restores your formats, preferences, and other settings to the factory default settings.

    Note: Some third-party applications do not create a backup on your computer when you synchronize. If you perform a hard reset, you may lose data in these applications and you need to reinstall these applications after the hard reset. Please contact the developer to find out which information is backed up during synchronization.
