Well, before you flash that firmware (looks to be 4.1.1) we have to make sure you can without bricking as you are on 4.4.2.@Mikestony , yeah I used SU. And okay, I'll check that out! So basically, I would just download this: http://www.sammobile.com/firmwares/database/SGH-I747/ATT/ and then use odin to flash it? I think I may need help using oden to flash because I have no clue how to do that.
Sometimes (at least with the Verizon variant) you cannot/should not downgrade versions.
I'll at least move this into the root forum for your device and check on that more tomorrow night.
I really need some shuteye now
