Ok. I understood your problem. This has happened a couple of times to me alsowhen I had updated to the latestfirmware but without having the latest emmc. In Plain words, uhave managed to update one such component and thesecond one is not yet done. If you wanna fix this up, I'dsuggest you flash your device to the latest firmware as per the Wiki Guide rather than using the SSU.

EDIT: APOLOGIES. SRY FOR THE ABOVE BUT I DINT READ THAT IT IS AT&T LOCKED. PLS SOMEONE ELSE ASSIST HIM WITH GETTIN THE IMAGES. AGAIN, DO NOT FOLLOW THE GUIDE UNLESS SOMEONE CONFIRMS IMAGES OF AT&T's AVAILIBILITY.
