Cherry Mobile Spark TV Hard reset

to unlock your Cherry Mobile Spark TV,
 I think you need to hard reset and refresh your phone..
But to reset your phone, you need to back up all files because this procedure will delete all of them. (Including photos, music, apps, games and so on.)
 1. Press the power button, down button , and home button simultaneously.
 2. Wait until Spark tv logo appear, then release the power button, while still pressing the two buttons.
 3. Recovery mode will appear. And then select wipe data, by using down button
 4. And your phone will reboot and it's done. Or if you have registered a Google account, you also try to          input the wrong code continuously.
 Then your device will let you input your Google account to unlock the pad,
   but if you haven’t registered a Google account, your
  blocked phone cause of too many pattern attempts,
 can only be unlock by doing a Factory data reset.
