Smartphone switches off Automatically

Hi
In order to do it you need an USB cable of the phone and download a Android Desktop manager program to your PC first..
than when you connect HTC with USB cable the program you downloaded will see it automatically.
when you download any Android " .apk " from internet you can load into your phone with that desktop manager..
Hope this helps!..if more help requires pls let me know.
