Hello, and welcome to XDA!
There are a couple (stock) options available to you.
With root: > AT&T Samsung Galaxy S 5 > AT&T Galaxy S5 General > [How-To] Update to G900A_OF3 - 5.0 and KeepRoot
No root (nor rootable): > AT&T Samsung Galaxy S 5 > AT&T Galaxy S5 General > [How-To] Update to G900A_OI5 - 5.1 (Unrooted Stock ROM)
Instructions are in the threads, any questions can go in the respective thread as well.
Hope this helps, and good luck!

[Completed] [Q] Tmo GS3 LTE Stock Android

T-Mobile Galaxy S3 LTE SGH-T999L
Hi there. I just want to flash the latest version of stock Android (L if possible, KitKat otherwise). The Google Now launcher isn't enough; I want the improved performance and efficiency and I want all the useless Samsung apps off my phone. After I root my phone, where do I get a simple stock ROM? All I can seem to find are custom ROMs with all kinds of mods. I just want stock Android or a very lightly-modified alternative. As far as I can tell right now the closest ROM would be CM.
Thanks.

Can't find an Android L ROM for your device.
But you should ask in the T-Mobile, Wind, Mobilicity, Videotron Samsung Galaxy S III > T-Mobile Galaxy S III Q&A, Help & Troubleshooting forum.

[Completed] [Q] Downgrade s3 from 4.4.2 to 4.3 possible?

I was running on 4.3 jellybean and I updated to official 4.4.2 ROM on my galaxy S3 GT-I9305. After that I am having a lot of issues with the phone and the overall performance and plus fast battery draining. I like 4.3 jelly bean 4.3 a lot so I tried to figure out any way to downgrade from 4.4 to 4.3... By chance I came across a thread regarding on how to downgrade 4.4 to 4.3
here is the link > http://forum.xda-developers.com/showthread.php?t=2744061
Unfortunately the method was for S4 but I think that it might work the same for the S3 model as well...
So can I use the same method for S3 GT-I9305 to downgrade from 4.4 to 4.3? or by any chance is there a more easy way than that?
Hi there,
There is some discussions about downgrade but only from 4.3 to 4.1. See the threads bellow:
