I'm under the assumption that this can recovery lost images, date etc,. However and because you've stated that you've preformed a factory reset.. The factory rest takes precedents over everything, even attempting to recover images and data. The factory reset would only be used as a late resort when your system/android is corrupted or failing to boot etc.. which doesn't include image recovery. Therefore and next time, before you jump to conclusions and preform a factory reset.. one could have recovered lost images and data.
