Not sure what could be the issue or if this will help, but maybe try updating your recovery if possible or use TWRP Recovery
instead? If you try TWRP, I recommend using an Odin tar file or a flashable zip as opposed to GooManager, as it's been known to soft brick devices.
Also, you could try *backing up* and then formatting your internal & external SD cards, and restore your files after doing a nandroid.
