The Parto PT 1037C works on android version 4.0, making it quiet easy to reset. You can go to your settings and then into the storage section. The option of factory data reset would be available as the last option on the list. By pressing the same, you would be asked for the security pin(if applied) and then the process will begin. After restarting, the tab would be rolled back to the factory condition, deleting all your data and applications at once.
