When cabs/apps/software tells you that it needs to reboot, it will reboot. Rebooting is powering down and back up, either by pressing the Power button or the soft reset button underneath the battery cover. A hard reset is a key sequence you press to wipe the device(send+end keys together then power, hold all 3 until the screen states hard-reset press vol up), which can also be done through the windows software in settings/clear storage. Clear storage is slated/stated to do more(in depth) as far as returning the device to original/core programming without losing the device programming.
