Returning to stock S3 - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

Hey there everyone,
I understand the whole flashing process, so don't crucify me yet. My question is this: I'm currently running CWM recovery and CM10.2 rom. My baseband version is I747UCUEMJB and I can't find a STOCK rom ending in MJB. I checked a few websites and there are only ones like LEM, LK3, etc. I'm pretty sure flashing anything other than MJB will result in a brick. Am I right? Does anyone know of which rom to flash to have a stock phone?
Example: http://samsung-updates.com/device/?id=SGH-I747
^ Does not have MJB.
Also checked this website: http://galaxys3root.com/galaxy-s3-unroot/how-to-unroot-att-galaxy-s3-sgh-i747/
^ the rom they had was I747UCALEM.
Advice?
Thank you in advanced.

Mjb is android 4.3 so find the 4.3 ROM on here somewhere and follow its instructions to do a clean install

[Q] 4.3 Stock for Odin?

Hey guys,
I'm trying to go back to a stock Touchwiz ROM from CyanogenMod 10.2. My only problem is, I can't Odin back to a stock from because the only Odin compatible file I have is 4.1.1 which my phone will no longer go to since my baseband was updated after trying a former 4.3 ROM.
Can anyone link me to a 4.3 ROM that I can flash in Odin? I'm asking because most of the ROM's I'm finding that are 4.3 require you to be on a TW ROM before flashing their ROM. Thanks.

This link is useless for me as it does not have a 4.3 stock rom listed in their official firmwares. They have only up to 4.1.2 which I cannot Odin back to since my baseband was already updated.

Do I have to be on a stock rom to use this? I'm currently on Quantum V3 and I don't have access to a stock rom to revert to since my baseband was updated.

No you don't have to be on the stock rom to use that, but the bootloaders are for 4.3 so if you haven't updated yet this will update you.
You can flash any rom you want to as long as you do not mess with the bootloader you will be OK. I do not know if this work on anything besides an at&t phone using it on anything else is done so at your own risk just the same as using it.
What about the recovery? any way to get a stock recovery image?

Downgrading from 4.4.x to 4.3

I was wondering if I may run into any problems by doing this.
I know that on an AT&T phone (i747), if you do that, you may lose your modem and needs to be reflashed (you get a null IMEI)
Is it the same on a SGH-T999? I was planning to flash this ROM:
http://www.sammobile.com/firmwares/3/?download=26636
Thanks
There is no 4.4.2 to downgrade from for the T999.
If you just have a 4.4.2 Rom, you don't need to do anything.
The firmware you linked is the latest available so you can flash it regardless of what you have now.
There is no 4.4.2 update for the T999 so yes you can flash it but it is not a ROM, it is firmware, please do not confuse these two they are very different!
Yeah... I'm afraid I am confused. What I did was to flash this:
http://forum.xda-developers.com/showthread.php?t=2690947
Isn't that a ROM?
However I would like to go back to 4.3, so I was just wondering if I could have any problems.
Sorry for the noob questions. I think it was clear to me, but I'm afraid it's not...
Thanks
Yes that is a rom, what you linked to in the first post is firmware which contains more than just the system and that is where you run into problems when downgrading

So if I'm on 4.4.4 right now, is there a way to go back to 4.3?

Yes, flash the link you provided in the first post or flash a 4.3 rom.. Understand this, flashing a rom will not determine if you can downgrade or not, flashing firmware will. Since there is no 4.4 firmware for the T999 you can still flash the 4.3 firmware. If there was a 4.4 firmware and you took the OTA or updated via Odin then the only thing you could do is flash a 4.3 rom, firmware will not be an option
Edit: oh and btw I accidently pressed the thanks button so you got a free one

[Q] Back to 4.3 Stock Rom to Unlock the phone?? HELP

Hello everyone,
I have searched the site for some ways to unlock my device. I am running liquidsmooth 4.4.4 and as far as I know there is no way to unlock customs Roms running 4.3/4.4, unless you go back to the original stock rom and use either AT&T or third party site unlock code. So, I called AT&T and they provided me with the unlock code and they told me the same thing, the unlock code will not work until you go back to the original factory stock rom!
So, I have been searching here for the right 4.3 stock rom and I found out many posts and I got confused which to use. I would highly appropriate it if any one can help me and direct me to the right source/process for 4.3 stock rom steps and installation so I won't brick my phone.
Thanks in advance

If your bootloaders are on 4.4, you can't downgrade them (or you'll brick!).
You can use Terminal Emulator to know which one you're on:
Code:
getprop ro.bootloader
Once you know which one you have, you can go ahead and grab its stock version.

Thanks for the reply, I checked the bootloader as you said and I got ( I747UCDLK3 ). So, I am guessing that I am still on 4.3 because the last bootloader update was through this process:

LK3 is 4.1.1. I'm guessing the 4.3 bootloaders update didn't work at all.
Now that you know you have LK3, just grab the stock firmware and flash it. (backup first)

This is really strange. So, if I may ask, how my bootloader is still 4.1.1 and I am able to flash 4.3/4.4 roms? Also, if I install I747UCDLK3 can I go back to 4.3 custom roms without updating the bootloader!!! because that what I did last time I follwed the steps in below web site to be able to flash 4.3 rom,,,,, but apparently I am still on 4.1.1 bootloader!!
http://forum.xda-developers.com/showthread.php?t=2387423
4.3 roms could still be flashed on older firmware. 4.4 roms too as long as they are not touchwiz. If its a touchwiz 4.4.2 rom you must have at least 4.3 firmware though.
Hi i want to know if i can flash an original 4.3 firmware my bootloader is I747MVLUFNE6 can i go back or i will brick my phone if i tried?
No you cannot downgrade firmware. You can only flash the same or newer builds. Or you can flash older roms and kernels, but nothing else.

[Q] Need help on updating Modem/Baseband Version.

I need some help on how to update my Baseband Version/Modem.

I believe CM11 will work fine with 4.3 firmware and modems. I would suggest using the MJ2 firmware and MJB modem, at least until you have decided you need even newer than them. An advantage to MJ2 is that it can be downgraded if you ever have need for that. A link to it can be found in the OP of http://forum.xda-developers.com/showthread.php?t=2252932. Another advantage is that it was released prior to the release of KNOX. Not only will this firmware/baseband combo will run CM11, it will run TW based 4.3 roms and many TW based 4.4.2 roms.
If you are wanting to get to the latest firmware and baseband, do not use the MJ2 firmware. Many people would recommend you upgrading sequentially through MJB, NE4, and to NJ1. Links to the MJB firmware can be found in the same post as the MJ2 I linked. Enewman17 has a thread regarding upgrading to NE4 firmware. http://forum.xda-developers.com/galaxy-s3-att/general/ucuemjb-to-ucufne4-firmware-update-t2808654
If you have an interest in unlocking your phone from your carrier, do it prior to upgrading to MJB and beyond. Once reaching MJB it can only be unlocked by your carrier or by using a paid service.

If i was to flash NE4,should i flash MG2 to MJB first and then flash NE4?
And also,do i have to do a factory reset while flashing these files?

Yes, I would recommend incremental updating: MG2 > MJB > NE4; as shown in the second thread I linked.
I am only on the 4.3 leaked firmware and official 4.3 baseband, I have not updated to NE4 at this point. But, I was on the 4.1.2 stock rom when I updated to the MJ2/MJB firmware-modem combination. I went back into that rom with no factory reset and no wipes. After a couple of days with no issues I flashed a custom 4.3 rom. I did do the recommended reset and wipes in the flashing process, that was due to the rom, not the firmware and baseband. Also, the link does not suggest resetting or wiping in the upgrade of firmware and modem. If you have any issues after flashing, then I would suggest the factory reset and wipes with possibly even a reflash of your rom.

i personally have never flashed one of the cm12 unofficial builds. i suggest you read thru the threads and see if people are having issues or not and then decide. i would also definitely make a backup of current setup if did decide to try.
if you did a full wipe between unofficial and official , i would imagine to be most sure way to avoid errors.
imho there is ALWAYS a risk in flashing/rooting/modding,etc.
good luck with whatever you decide.

Back to stock ROM Galaxy S3 i747

Hello people, first of all I dont know if im in the right place, Im new to this forum.
My situation is that I want to restore back to stock ROM my i747 with a custom rom running on android 4.4.4 with SlimROM, my Kernel is 3.4.104-cyanogenmod-g38a4e52
Baseband i747UCUEMJB
I passed through 4.3 stock ROM, then i flashed to Cyanogen 12 with android 5.1.1 and now Im with SlimKat with android 4.4.4. I want to go back to stock ROM, but I read about the locked bootloader on newer versions of android, I dont really know much about this thing, but I think that is if I want to go back to 4.1, im i right
The thing is, can I go back to 4.3 stock rom
Thank you.
The bootloader is not locked; however, it cannot be downgraded to anything before 4.3.

Thank you guys for your help, so Im good as soon as I flash to 4.3 stock, what about the recovery, is that made by Odin? Or should I first flash a specific one?
About the 4.4.2, is it better than the 4.3 and would I be able to go to 4.3 in case I get the NE4?
Again thank you for your answers.
Once you upgrade to the 4.4.2 bootloader, you cannot downgrade to the 4.3 bootloader.
Stock Recovery will be installed by Odin.
