I am trying to downgrade an AT&T S4 so that i can factory unlock it.

I downloaded Samsung-Updates.com-SGH-I337-ATT-I337UCUAMDL-1367050591 from a couple different mirrors and they're all corrupt so I don't even know if this version works.

edit: I guess ..What's the latest firmware the *#0011# trick will work on?
Or is this even possible? It has UCUAMF3 installed
(And I have read up on MF3 and still don't understand if this is possible.)

Thanks in advance for any help! I have already been googling for a couple days.

Sadly no. Once you update to MF3 or MK2, you are stuck on it.

It will brick it. Then if your on mk2 it will be a fight to repair. If your on mf3, it's not so hard, you can odin back. This phones bootloader is locked. So no downgrading.
