Those images are not fastbootable. They are only for twrp, if you have a backup of the twrp folder from your sdcard, and you for whatever reason need to start from stock again, push the twrp folder back to the sdcard, then while in twrp, restore that backup.

Actually, now that he has recovery images, he doesn't need kf2-srt.
