Need General GS3 Help and Info topic

Hello folks.

I am new here and am not sure how it all works so please forgive me if I have posted in the wrong spot or am asking something that has been beaten to death already.

I have a AT&T GS3 I747 . I received the OTA 4.4.2 update for it and used it just fine. One day i got a bug in me to root and flash it. I rooted it, installed CWM 6.0.47 or something like that and installed Gummy Rom running kitKat 4.4.4.

I would love to return my phone to 4.4.2 with or without root. Is this possible? I have read and read to NOT take these backwards after JB 4.3

I have looked until I was blue in the face for a rom to use and am drawing blanks. I probably found one once and didnt know it. I can flash and all that and do it regularly, I just don't understand all the fancy lingo so I probably overlooked what I am looking for.

So bottom line, is it poissible for me to go back to stock 4.4.2? I would love a stock rom minus all the at&t bloatware since I will be unlocking it to straight talk.

Thanks for your time and once again, my apologies for dragging this all up again if it has been covered already.
