Hmmm... I can absolutely assure you that this folder (even the entire system/ folder) is meaningless (=not required), especially after you have reset your device. A factory-fresh device comes without anything except for the tts folder on the "externally" accessible disk.
The official screen savers are on the main partition, to which you don't have access, so you can't have deleted them.
Well, the only thing I can suggest now is: try the "simply debricking" method from the sticky thread in the dev corner. This works 100%, but requires some work. Or ask Amazon for a replacement.
