Since currently (as of writing this post) there’s no stock firmware available for AT&T Galaxy S5, you can use a SafeStrap Recovery backup to restore your AT&T Galaxy S5 SM-G900A. Now, this is the Android 4.4.2 ND3 firmware, it will only work if you have not upgraded your bootloader past ND3 most likely.

For those of you who need to fix “firmware encountered” error or you simply want to re-install stock firmware on your Galaxy S5, you can easily do so using ODIN and stock firmware tar.md5 file.
This will get your Galaxy S5 completely back to 100% stock and unrooted. This can also be very useful if you are returning your Galaxy S5 to the store for warranty purposes or you want to unroot your phone completely.
