Back to 4.3 - T-Mobile, Samsung Galaxy SIII

My SGH-T999 currently has slimkat 4.4.4 I have searched through this thread to see if it possible to go back down to back down to 4.3, however it appears that the because 4.4.4 has new bootloader this cannot be done and could brick the phone due to knox? Can anyone confirm this for me?

Are you looking to flashing the stock full firmware or a custom rom? You only flashed a 4.4.4 ROM not firmware, and there is no official 4.4.4 for any of our S3 variants, only 4.4.2. T999 doesn't even have a 4.4.2 update as of now, so you can go back to 4.3 firmware if you would like

Yes, I'm trying to flash back to the 4.3 stock image. Basically I have rooted, and flashed a custom Rom (slimkat) and I would like to back to the stock experience.

[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?

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.

Help with gs3 root

Hey guys. This may have been asked already but i am coming from verizons gs4. and over there you can oly get custom recovery if youre on mdk bootloader.
I just bought this phone for my brother and it came with 4.12 (MG2)
I see everywhere that people were able to get 4.3. i tried updating through phone and through kies and says its up to date. so now my question i guess is what bootloader do i need to be on or what 4.x.x do i need to be on in order to root and get custom recovery to flash custom roms?
any help will be greatly appreciated.
I recommend not updating to stock 4.3 ROM as this will install Knox and you will have a non-downgradeable bootloader. You can use Odin to flash Philz Touch which is based on CWM. From there, you can flash custom ROMs.
Some ROMs require a 4.3 bootloader, but these would tend to be based on the stock Samsung ROM. I am running the latest Validus 4.4.2 on a stock Bell 4.1.2 bootloader without a problem.

Oh ok. Well I just succesfully rotted and installed latest touch cwm.
so if I stay on 4.1.2 I can basically flash any kitkat roms? Because I dont want to install a tw rom.
So another question what are some good 4.4 kk roms? As in stable for daily use that I could flash
Sent from my SCH-I545 using XDA Premium 4 mobile app
Most kitkat ROMs will work with a 4.1.2 bootloader based on my experience.
I like the Ground Zero ROMs and use them on the s3, Moto Atrix HD, and Nexus 4.

[Q] Stock 4.4.2 to Stock 4.3 via Odin?

Hello!
I'm just got a replacement Note3 because I cracked the screen and it is running 4.4.2. My phone is still on 4.3. I've been reading about how you can't go back to 4.3 from 4.4.2 because of bootloader reasons, but it seems to be mostly people with custom roms. Is is possible for me to flash a stock 4.3 to the new 4.4.2 phone without any problems, or will the bootloader issues apply.?

No, you cannot odin back or downgrade from android 4.4.2 to 4.3
even if you never rooted or flashed any custom roms.
Good luck!

Going back to stock from cm11?

I'm on cm11 m9 and it's been acting hellafunky lately, so I figured I'd switch back to stock to see if that cleared it up. I know TW is still on 4.4.3 but I can't find a flashable image of it anywhere. Is it possible to go back to stock, or are the cm bootloaders and such to new to be able to do this without bricking the device?
What bootloader is on your phone? Is it an i747 or i747m?
If you are on 4.3 or higher, you cannot flash back to stock unless you use a ROM that has been specifically compiled for flashing in Odin.

On bootloader NE4, I was able to flash back to to stock using the image in here: http://forum.xda-developers.com/showthread.php?p=56510020
Everything is working swimmingly.
'ENEWMAN17' threads are the most helpful when it comes to returning an SGS3 device back to stock KitKat ROM. You must strictly adhere to his instructions. Good luck!
Iv flashed my cm11 back to stock using cwm and flashing a odexed 4.4.2 samsung rom without any problems.

If the phone is an i747m, I recommend getting a stock ROM from sammobile. com. I'm not sure if a bootloader and modem file is included in the enewman17's thread but flashing an i747 bootloader and modem onto an i747m could result in a brick.
