I hope someone can help with a dilemma I have.
I need to flash back to stock rom and do a factory reset on my AT&T SGIII - this I know how to do . However, what I don't know is if the links I've found for tar files for a stock restore (like the one posted here)are for the ice cream sandwich version that launched with the phone, or the newer jelly bean version.
If it is the older version, once I'm done restoring it back to stock and factory settings, will I get an option to update to jelly bean thru AT&T?
Or do I need to find a stock AT&T jelly bean file to flash? If so, where do I find that?
any help would be appreciated. Thanks

this shouldnt be posted here check the general section for going back to stock
Did you update your phone to AT&T 4.3 stock rom via an OTA update? If you did, do not flash any rom that includes an older bootloader as the flash will brick your phone.

No. Ever since going to the Sonic FreeGS3 Resurrection rom, I have been on the 4.1.1 version. I've never been to a more current version than that since that was the last version update for this rom and I liked it just fine.
Even though I'm not wild about having to return to stock, I am at least excited about (hopefully) being able to go up to the latest version released by AT&T. But I wasn't sure if I need to flash a stock 4.3 version AT&T rom (or even where to find that) or if I could just flash the original released stock rom and then be prompted with OTA updates to go to the newer versions.
Any thoughts or input is greatly appreciated.
The latest version of the AT&T ROM is 4.3 which can be done via an OTA update or Kies from a stock 4.1.1 AT&T ROM.
Any reason you need to return to stock? Personally, I would not go near 4.3 as it's not required to install KK ROMS and, once on 4.3, rooting, etc. becomes more complicated.

I have to for work. That's the only reason I'm going back to a stock rom. Plus I want to trade my phone in after a few more months once my contract is up.
Is it possible to come back from a 4.4 rom to say 4.2 or 4.3 stock ROM? Can I ODIN back?
Currently not able to get MMS/Group messaging to work on the current 4.4 rom. Tried updating modem, adjusting settings...still no luck and I need it for work. Appreciate any help
Which phone do you have?

AT&T S3
You can go 4.4 -> 4.3. However, you cant get the unrooted stock rom of 4.3, since Samsung/AT&T didn't ever release to the public (It was all OTA).
If you went 4.2->4.3 OTA, then your bootloader was upgraded. As you've seen on these forums, downgrading from 4.3 to 4.2/4.1 is a big no-no unless you want a brick.
Example:
4.2 ---(OTA UPGRADE)--> 4.3.
Rooted+cyanogen 4.3
cyanogen 4.3-> cyanogen 4.4
cyanogen 4.4-> cyanogen 4.3
cyanogen 4.3
( ^ what I have done)
NOTE: After I got the OTA, I have never tried going back to stock. You can use rooted roms that are CLOSE to stock. But I wouldn't suggest going stock because of knox and blah blah blah.
Were you ever on stock AT&T 4.3? If you were, your bootlaoder was probably updated so you can't install an older bootloader. You can load a older AT&T ROM using mobile Odin which does not flash a bootloader or modem.
I never went to 4.3...straight from 4.2 to 4.4

So I could go back to a 4.2 TW rom if I was never on 4.3 OTA? (or any 4.3 for that matter)

Yes, you just need to find a stock AT&T ROM that is flashable in Odin.
I have a quick question. I am on a stock rooted 4.1.1 att sgs3. I was curious if i flashed this rom/kernal,[ROM/KERNEL][4.4.2] Quantum 3.54 & QuantumKernel 3/7, would i be able to go back to my stock rooted rom if I wanted to? Thanks in advance.
Looks like you are trying to flash a custom ROM. Don't know much about these particular ROMs you mentioned but you need to your research thoroughly on custom ROMs before flashing. You may know most Custom ROMs don't come with their own bootloaders but still have to rely on a manufacturer's bootloader to run. You should, therefore, avoid any ROM that may update your bootloader because this is the only way that you would not be able to return to your previous stock version. If the ROM simply updates the system without mucking with your bootloader, there is no reason why you may not be able to return to stock.
I had an AT&T SG3 on stock 4.1.1 and I was able to flash KitKat (4.4) based CM11 and return to stock 4.1.1 without any hitches. Finally, whilst you are still on stock 4.1.1 I would suggest you take advantage of all the flexibilities offered by this Android version especially free unlocking before you begin tinkering with firmware.
So as long as I dont update my bootloader, I should be fine on going back to stock rooted 4.1.1? Thanks for the info!!
So how do i know what roms dont mess with the bootloader?
Most ROMS do not include an aboot file. I have flashed CM11, Validus, Slim, and Cyanfox and none of these altered the bootloader.
I suggest that you find a ROM you like, unzip the file, and look at the updater script to determine which bootloaders are required to install the ROM on your phone.
Ok guys, thanks for the tips. I just didn't want to get stuck on a firmware where i could not have root anymore or go back to a stock rooted rom.
Okay, so my phone is currently running 4.4.2 Cyanogenmod right now, I had to find out the hard way that I cant jump back to 4.3 due to the bootloader but will it be possible to install the stock 4.4.2 safely once its released? Or is there a way to go back down to 4.3 that I'm missing..

Don't know how you got the impression you can't go back to 4.3 from Kit-Kat based CM. CM, like most stock ROMs, doesn't come with its own bootloaders but relies on manufacturer's bootloader to run. If you went to CM from stock 4.3, chances are your bootloader was unaffected and still remains at 4.3. You can check what bootloader your phone is on by going to settings and seeing what you have under baseband. If it's UCUEMJB then you have the 4.3 (MJB) bootloader and you should be able to use custom recovery to flash a stock 4.3 restore image.
If history is anything to go by, you would be unlikely to get the (newly released) 4.4.2 update OTA if you are not on a full stock (or stock-based) ROM. I would, however, not be in a rush for OTA as we can always trust the good guys in the development community to come up with a manual update process shortly. If you still want to revert to full stock 4.3, then you can follow the instructions in the thread below ...

Your right!
Used the process you gave me and it worked, I had been trying to use odin but I supose a simpler solution was better. Thanks again!
I just switched from stable CM10.1 to stock 4.4.2 this week. It sucks. Performance and battery dropped drastically. Will be going back to CFW asap.
Hey guys I am trying to update my galaxy s3 to kitkat. I am running galaxy s3 at&t variant 747 rooted 4.1.1. I747UCDLK3 update to kitkat. I realized I need to update to 4.1.2 first before doing the 4.3 update. I can't seems to find files I need for 4.1.2. Can someone point me in the right direction. Thank you for your help.
Are your running stock 4.1.1? If you are and your phone is not sim unlocked, unlock it using the free method. Once unlocked, use Odin to flash back to stock unrooted 4.1.1 and then run OTA until you get to KK. It's a longer process than trying to flash straight to 4.4 but is a safer method for people that are new to flashing ROMs.
I am on the stock rom 4.1.1. Does CWM recovery need to go back to stock as well? That is a good idea to unlock before I update.
If you flash back to stock 4.1.1 with Odin, it will wipe everything and put the phone back to completely unroot stock and stock recovery. Stock recovery and being unrooted is required for OTA updates.
Ok is this the link to unlock phone?
http://forum.xda-developers.com/showthread.php?t=2529200
Yes, that's it.
I can't seem to find 4.1.1 rom file links seem to be bad on unlock page.
There are stock rooted 4.1.1 images here: http://forum.xda-developers.com/showthread.php?t=1739426
You can use the free unlock method even if the ROM is rooted.
For some reason the at&t mirrors don't seem to be working either.
Mirror2 for the stock rooted 4.1.1 works for me.
I would like to root again after kit kat Is it easy to root with knox? Does unlock stick through kit kat? I really appreciate all of the help. Great website. Great people.
Many people have had success with rooting by using Towelroot.
The sim unlock is permanent.
Let me know how it goes for you @thepar. I expect to be updating to kitkat in the coming week.
For the benefit of those searching the forums to unlock their phones my experience may be of help to those on 4.1.2 or possibly even MJ2. I have had my SGS3 since June 2013 and only allowed one update, that was to 4.1.2. My phone was rooted long ago, but I just unlocked it earlier today and that was with a custom recovery in place and without unrooting. In my case I did not revert to the 4.1.1 rom. I did downgrade the modem to dlk3, that of 4.1.1 while leaving the rom and bootloader at MG2. After completing the unlock I upgraded the modem back to MG2. I have confirmed that SMS, MMS, phone, and wifi functionality is intact.
In truth, I will probably not go back to stock to get to kitkat. I am considering upgrading to the leaked MJ2/4.3 bootloader and MJB modem and then flash a kitkat rom which will work on them, there are several.
I just did the unlock yesterday. I need to find someone with a t-mobile sim to test if the unlock worked. Will I still be able to update the OS even though it is on rooted stock? What will it update me too?
I am kind of debating if I should install a custom rom minus KNOX.

If you want to run an OTA update, you need stock recovery and an unrooted system.
I have a stock recovery but the os is rooted. I don't mind using oden to update the os. I might be better to install a rom with knox removed. I can't seem to find 4.1.1 stock unrooted. I did find 4.0.1 ICS.
You can find a stock ATT 4.1.1 ROM on sammobile.com.
You cannot use Odin to flash a stock KK ROM because it was never released in an Odin format by ATT. ATT provided the KK update via OTA updates. Complete KK updates were provided for i747m only.
Thanks so much!! downloading now.
Let us know what happens. Cheers
I have decided to go custom rom route. It is better to update stock ota first then install custom rom or custom rom straight from 4.1.1?
