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.!

    Performing a hardware reset

    You may have to perform a reset if the device freezes (i.e., device no longer responds to the buttons or tapping on the screen).
    A soft reset allows your device to get a fresh start, similar to rebooting a computer. This will restart your device and adjust memory allocation. All records and entries are
    retained after a soft reset. Unsaved data in open programs may in some cases be lost.

    Performing a Warm Boot

    1. Remove the stylus from its holder.
    2. Lightly press the tip of the stylus to the reset button located on the rear of the PA600.
