Hello, I know there are many threads on restoring a bricked S3, some of them for hard bricks, and some for soft bricks. None of the guides I found by scouring these forums provided all of the answers I needed.
INFO PLEASE READ ALL
Here I hope to outline how I restored my T999 Tmobile S3 to stock firmware after the 4.3 MJC update, and after bootloader bricking the phone. I do assume you are capable of using ADB, ODIN and TWRP. I believe this method will work for other S3 models, but I have no ability to test it. If it will work, firmware and debrick IMGs will have to be found for the specific device. The T999 firmware and IMGs will NOT work with other devices. This will restore to stock UVUEMJC 4.3 firmware. Will not be rooted, but existing 4.3 roots for the device should work.
I AM NOT RESPONSIBLE FOR ANY DAMAGE TO YOUR DEVICE. THE TOOLS USED IN THIS GUIDE HAVE THE POTENTIAL TO BRICK, OR OTHERWISE DAMAGE YOUR DEVICE. USE AT YOUR OWN RISK
So as context, I had been flashing different ROMS; then I updated to stock 4.3 UVUEMJC Firmware. This updated the bootloader, and installed the Samsung KNOX security upgrade. Both the bootloader and the KNOX are problems regarding rooting, rom installation, and downgrading (which I still have not achieved)
After upgrading, I installed a vanilla rootbox. I then attempted to flash the UVDMD5 bootloader at mnasledov's thread here: http://forum.xda-developers.com/showthread.php?t=2282603
Lacking my present understanding, of the 4.3/KNOX problems, I managed to brick my phone by effectively attempting to downgrade the bootloader. Phone appeared to be hard bricked.
I tried many things to fix the phone, these are what worked:
GUIDE:
1. Get a Class 10 MicroSD card and follow KAsp3rd's guide to boot from the SD card: http://forum.xda-developers.com/showthread.php?t=2439367
You should now be able to boot to download mode, recover, and system if it was undamaged when you bricked your phone.
2. Boot into download mode and install TWRP via ODIN
3. Boot into your new TWRP recovery. Do an ADB sideload of the KNOX removal script found in Kaito95's thread here: http://forum.xda-developers.com/showthread.php?t=2507931 Check the clear cache and clear dalvik recovery boxes. You have to do an ADB sideload, because your SD card is in use as a bootloader.
4. Use ODIN with Download Mode to Re-Partion by flashing the PIT file found in invisiblek's downloads here: http://forum.xda-developers.com/showthread.php?t=1848267
The Re-Partition box will have to be checked, and the PIT file loaded under Re-Partition. This is what I believe corrected the download mod fails I had been getting.
5. Use ODIN and Download mode to flash the original UVUEMJC firmware found in DocHoliday77's thread here: http://forum.xda-developers.com/showthread.php?t=1949687
6. In TWRP do a factory reset, and a fix permissions. Reboot into system, (without the SD card)
If all went well you should be in business!
If you see any error in my guide, or have another correction, please let me know. If I have posted this in the wrong section I'll be happy to move it.
I hope this helps you.
ROOTING:
So after fixing my phone via the steps above, I still wanted to root it. To root it I simply ODIN flashed mrRobinson's rooted/deKNOXED 4.3 stock rom from here: http://forum.xda-developers.com/showthread.php?t=1771687
It seemed very stable to me.
I then decided to use TWRP to install the CyanogenMod 10.2. If you choose to install CM, I believe you must use the 10.2 branch, because it is 4.3 based. Prior versions are not 4.3, and won't work with the 4.3 bootloaders. You can find the appropriate CM download by selecting your device here: http://download.cyanogenmod.org/ The T999 is d2tmo.
EDIT: YOU CAN RUN OLDER VERSIONS AFTER UPDATING TO 4.3.
This was pointed out to me by Adreaver. I personally am using rootbox 4.2.2 after having done the 4.3 official update. Any rom for the device should work, but certain lines may need be removed form the updater script. I am still looking into this.
NOTES
This has been confirmed to work on the T999L, but you need a different PIT file, and different firmware for the model. See @mrspock08 's post on page 2 of this thread for more info on the T999L
THANKS
I could not have debricked my phone or created this guide without referencing and using the work of several fine members of this forum. Particular thanks to:
@mnasledov for providing a thread with information about bootloaders.
@KAsp3rd for providing a way to boot from the SD card, enabling the entire rest of the debrick.
@Kaito95 for the deKNOX script.
@invisiblek for the PIT file for correctly repartitioning the phone.
@DocHoliday77 for the MJC 4.3 Stock Firmware mirror.
@mrRobinson for the rooted MJC Stock firmware
@Adreaver for correcting me that you can run an older version of android
And the threads of many many others who's work I read through while learning about how all of this works.
Nice guide. I think @DocHoliday77 could use this method because I believe he bricked his phone the same way.
Oh, and I believe you might have made a typo SDB is actually ADB Android debug bridge.

Nice writeup. I assumed that a bootloader brick was the point of no return, thanks for proving me wrong.
Worth noting that you can flash any d2tmo ROM on the new bootloaders, even cm9 or 4.0.4 tw, but you may need to remove asserts from the updater-script.

For most phones the bootloader brick would require JTAG; fortunately several of the Samsungs have the SD as default boot.
And you can flash older ROMs? I was unaware of this; every attempt I've made to run something older has resulted in a getprop(ro.bootloader) error. But that updater script assert makes sense. Thank's for letting me know. I'll check that out and add it to the OP

Great guide, thanks a ton to @TronMinecraft for this writeup! I've been lucky and haven't bricked my S3 T999L (the T-Mobile LTE variant), but a relative wasn't so lucky. She took the OTA upgrade and when she wasn't happy with the result tried to just restore to her old 4.1.2 backup. Needless to say she bricked her phone.
So, I can confirm that this method DOES work on a T999L. However, there are a couple of things to note (these should be no-brainers, but in the interest of saving questions from the newbies out there...) Of course like Tron said, I take no responsibility for damage to your device should you try this. I can only tell you that it worked fine for me. Here's the things to watch out for, listed by the steps in the OP:
4. Make certain that you use the correct PIT file for the T999L. The proper PIT file for the T999L is the one DocHoliday uploaded here http://forum.xda-developers.com/showthread.php?t=1848267&page=3. Do not use the regular T999 PIT file from @invisiblek's first post in that thread, which is what was linked to in the OP.
5. Make sure you use the correct firmware for the T999L, NOT the T999. If you're trying to recover from a brick then most likely you're going to want the Original UVAMB7 firmware (JB 4.1.2), since it seems most bricks lately are caused by trying to downgrade after flashing the 4.3 update. Of course if you want to you can also flash the UVUBMK4 (4.3) firmware and get the complete stock 4.3 system, including the bootloader, KNOX, etc.
However, if you're just recovering from a brick and want 4.3 I would recommend not just flashing the UVUBMK4 firmware directly. Rather, I would flash the older UVAMB7 firmware, and then once your phone is back up and running flash DocHoliday77's UVUBMK4 4.3 Rooted, deodexed_KnoxFREE ROM from http://forum.xda-developers.com/showthread.php?t=2370981&page=58. Once you've done that, just flash the updated modem from http://forum.xda-developers.com/showthread.php?t=1880987 as needed. This way you end up with the full rooted version of the 4.3 firmware but without the 4.3 bootloader which includes KNOX and causes so many problems with downgrading.
Of course that's just my two cents. I've been running my S3 with DocHoliday's stock UVUBMK4, KnoxFree, rooted ROM with the UVAMB7 bootloader and UVUBMK4 radio for over a month now and haven't had any problems. As always, your mileage may vary.

Thank you for confirming this worked for somebody else. I'm working on a slightly re-factored version of this based on input, and I'll be sure to note your findings about the T999L. Thanks!

This really isn't quite the right place for such a question. A search will yield you great results.
But yes, there's no reason you couldn't if you're sure you have the right firmware for your GS3 model. However if you simply want a stock update, I'd just use the OTA update function, or kies. Its a bit safer than manually messing with Odin, and won't void your warranty.
Very useful thread. Bricking is actually a lot easier than I thought.

You CAN NOT DOWNGRADE 4.3.
This guide is to unbrick you and return you to 4.3 if you tried to downgrade (which won't work, ever).
Sent from my SGH-T999 using XDA Premium 4 mobile app
Actually, from my own experimentation you were right, you can in fact downgrade from 4.3. You just can't flash a rom that tries to change the bootloader. You cannot downgrade the 4.3 bootloader; but there isn't any reason why you can't run an earlier version of android.
I am currently running 4.2.2 rootbox AFTER having having done the official 4.3 update.
I did this with TWRP, and a rootbox flashable zip.

You did not downgrade. You flashed a custom ROM.
An example of downgrading would be a user on md5 flashing ljc with Odin. This puts bootloader, ROM, kernel, and baseband exactly as Samsung intended when LJC was released.

Okay, thank you for the clarification. I was incorrectly applying the term downgrade.
Hey everyone,
I previously had the UVUEMJC stock ROM from tmo. This was an OTA upgrade from 4.1.2. If I would have known about the new KNOX counter when I upgraded, I probably would not have. Now this counter is showing a '1' which voids my warranty (Check this XDA thread). Oh well, no fix thus far so I can't worry about that.
Anyway, I've recently flashed with the sammobile latest 4.3 ROM. When I attempt to check for a software update, it takes forever and finally tells me that my system was modified and I can't update. Checking the Device Status under settings, it shows it as 'Custom'. So, is there a reliable ROM that I can get that would fix the OTA upgrade procedure? Am I just screwed, for lack of a better term, and stuck with flashing to upgrade?
Currently looking at the deodexed ROM from Doc (Link to thread) to reflash my device so I can at least work on other things without KNOX being in the way.
Anyone have any suggestions if I should go for this ROM or another? Can I even restore this ability to update OTA?
Lastly, as long as I am sticking with a 'stock-revised' ROM, will I retain all my apps, settings, and user data?
Thanks guys,
Johnathan
You can only update via ota if you are 100% full stock. If you must have this back, you have to flash the official firmware via Odin.
Check out saranhi's StockMod rom too. But if you just want stock, rooted, with no knox, flash the root66 firmware with odin. (With root66 you MIGHT get notified of an ota, but it will fail if you try to use it)

I attempted to unroot my phone via downloading the SAMMOBILE 4.3 ROM and flashing it via Odin, and that didn't work. Do I need to do something else other than flashing the ROM?
BTW, thanks for your work, etc. on this forum. Is there a deoxed ROM for the t999? If I can't get back to original, might as well get this thing as slim as possible, etc. Lastly, if I use another ROM other then a stock one, will I need to save data, reinstall apps, etc?
Thanks,
Johnathan
First, go to my firmware thread. Stickied in development and linked in my sig. You can get all firmware there and the download should be much faster.
Im not sure why odin didnt work, what firmware build are you on now, and what did you try to flash?
You can find the deodexed stock roms in development section. They're there, you just may have to dig back a few pages.
Check out saranhi's StockMod and enewmans S3RX if you want a modded stock. If you go to a cm/aosp based rom, you will have to wipe data. Not always needed when just updating, but it is recommended for best stability.

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

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

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

T999LUVUBNF4 Root
Hey, I've been trying to root my S3 running the T999LUVUBNF4 firmware, but I'm having trouble. Towelroot doesn't support it, I haven't seen anything about a Root66, and I've heard mixed reports on CF-auto root. Does anyone know if there is a workable solution yet? How would I go about flashing SuperSU? Thanks.
Okay I've recently just flashed the root66 firmware that gave me supersu and all that.
My question is... Where do i go from here?
How would i proceed to
1) Install TWRP?, which version as well? Is 2.8 d2tmo fine? Can i have some instructions whether i use TWRP manager(goomanager doesn't seem to exist anymore) or do i have to go into download and flash through odin 3.09?
2) Installing a custom rom? I want to install Paranoid Android 4.6 beta 5 for D2lte but i'm not sure how to go about it. I have already downloaded the rom itself but not sure how to proceed from here. Also, how would i get the working and latest version of Gapps? (Also, can you tell me how to install Cyanogenmod 11 for d2lte as well?)
3) What are some cool apps to get?
4) Which root apps/roms/softwares will brick my phone? I'm never sure which thing will work and which won't.
5) how do i install xposed?
6) How do i remove all the bloatware? and how would i got about flashing through my phone without using the computer? is mobile odin compatible with my phone?
My phone is the SGH-T999L and i have no idea if i have a locked bootloader and how i would go about and bypass the limitations of this locked bootloader

Please don't post the same thing on multiple threads. Not being rude but it doesn't help at all
Rooting SGH-T99L with T999LUVUBNF4
I've read most of the more recent posts, and it is still unclear to me how to root my T999L which is already on the T999LUVUBNF4 baseband and build. I've seen references to cf-auto-root (like serio22 above), but the T999 (which I believe works for T999L) is based on T999UVALEM, which is 4.0.4 ICS. I certainly don't want to downgrade that far. The latest firmware on the first page of this Root66 thread is T999L_UVUBNC1, and there was a post indicating better reception with the newer modem, so I'd rather not downgrade that either. If I flash T999L_UVUBNC1 will my baseband remain intact (BNF4)? Or should I wait for a pre-rooted T999L_UVUBNF4? Or is there a better way altogether to root my T999L/BNF4?
Also, for other n00bs reading this, it's pretty clear that towelroot doesn't work on BNF4.

Stock I have installed as Flash PureStock Rom + Secure UVAMB7 Kernel (from http://forum.xda-developers.com/showpost.php?p=43772060&postcount=3) -- again, in multiboot -- and tried installing OTA on top of that. Got "error executing updater binary in zip"
What am I doing wrong?
Thanks
slimkat v9 to stock tw
Please help me. I have a sgh-t999. I want to know is it safe to install stock tw t999_uvuenc2. I'm currently running slimkat v9. My baseband is t999uvuenc2 and my android version is 4.4.4 i really want my s3 to revert back to stock. Ive been asking to the roms posted in this unit if it safe to direct flash but i havent got a good advice. I really want the stock touchwiz. Pls help me.
Which firmware to use
After I un-bricked my SGH-T999 with the debrick image sdcard ( YAYYY), I was able to boot with the stock 4.3 rom again.
I reflash the root66 4.3 firmware hoping it could get the correct boot image back in place. However it got stuck at the Samsung logo.
So I went into stock recovery and did a wipe/factory reset. Now I can still boot with the debrick sdcard but I am back in JellyBean (4.1.2 T999UVDMD5).
Which firmware should I flash 4.3 or 4.1.2? And did I miraculously downgraded my firmware ( I thought it wasn't possible) ?

If you are still on the original bootloader and modem you should be able to revert to stock 4.1.1 by simply restoring the backup from your recovery. Before you attempt to do so verify that you are indeed on the 4.1.1 bootloader. This can be done with the Phone Info *Samsung* app by VndNguyen (?sp) from the playstore or by a couple of terminal emulator commands:
Code:
getprop ro.bootloader
getprop | grep version.baseband
If you do not already have terminal emulator installed, it may have come with the ROM, you can get it from the Playstore. It may also be a part of CWM recovery, it is part of TWRP I know for sure.
If it turns out you are on a newer bootloader and modem then go with a stock ROM that matches the bootloader and modem on the phone. To run a lollypop rom you will need to be on at least the NE4 bootloader and modem.
Thanks for a very helpful reply. I m going to follow your instructions. Will soon replay. Thanks again.

Okay got Samsung phone info app.
Boot loader version -------I747UCDLK3
Baseband version -----I747UCDLK3
And please explain LATEST NE4 BOOT LOADER.
Thanks
You are currently running the LK3 bootloader and modem. If I am not mistaken that's a pretty old one (original?). You will have to update to NE4 or newer firmware before you can flash any of the newer roms. They will not boot in the older ones.
Your firmware is actually the only one available for download so I recommend flashing it via Odin and factory resetting. Then update using the Software Update option in Settings > About Device.
You can download your LK3 firmware here: http://www.sammobile.com/firmwares/database/SGH-I747/
You may have to run Software update several times to fully update.
That is probably the safest and easiest course you can take.
After that, flash the latest custom recovery of your choice, then flash the rom you want.

BTW, after flashing the LK3 firmware, you might want to consider using the free Sim unlock method. (Should be pretty easy to find).
Once you update past 4.3 you can no longer use it. It will allow the device to be used on other carriers networks, which can be beneficial if you ever want to sell it or switch carriers.

What DocHoliday77 suggests is probably the safest method to get what you want. After each update the system will force you to wait 24 hours before you can make the next update. That would be three days to get to NE4, the first 4.4.2 release by AT&T, which you need to run lollipop ROMs. If you want to update to the current release (NJ2) that would be two additional days.
You can shortcut the required waiting period by manually advancing the system date after each update.
In addition to not allowing you to use the free unlock, once you take the 4.3 bootloader it prevents you from downgrading bootloaders. Newer bootloaders do the same, downgrading will be a thing of the past. (I never took the official 4.3 bootloader until the stagefright scare came along and I went from my older custom ROM to a new release.)

1:- Okay I fully understood what I have to do to flash lolly pop . But confused a little bit . If I have original boodloader than it should be easier to restore my stock 4.1.1 . Backup (still not clear) .
2:- I am out of USA. The device in unlocked. I am using ZONG sim on it. So the question is can I still update the device via OTA.
Thanks

When you say original bootloader I don't know which you have. My i747 came with 4.1.1 but before I could get it out of the clerk's hands they had taken the OTA to change it from DLK3/4.1.1 bootloader and stock rom to MG2/4.1.2 bootloader and stock rom. Even more confusing I have read reviews that state the SGS3 was originally released with android 4.0.4.
If your original bootloader was older than 4.3 (MJB) AND you have never upgraded to MJB or newer, then you can safely return to stock 4.1.1.
To get OTAs you need to be on the stock ROM, at least you do in the USA. I don't know if that holds true elsewhere.
I can confirm the S3 was originally shipped with 4.0.4! We were updated pretty quickly though.
As for the OTA'S, you do have to be full stock, not rooted. But you also have to be on AT&T network.
I don't know how far back the OTA'S are hosted around here, but enewman17 has several threads that provide the more recent ones. Hopefully someone will have the older ones. If I am not mistaken, you will have to update incrementally once you reach 4.3. (it's probably safe to jump straight to a 4.3 build if you can find the right firmware for it. But don't hold me to that as I am not 100% certain.
I'll look to see if I can find something you can use too.

I am not clear about boootader version (PHONE INFO SAMSUNG APP SAYS ITS i747ucdlk3 ) but I know when got this thing. It was android 4.1.1 . Which I have back a backup. As per I am out of att network and I can't get OTA,s so I don't need to revert to 4.1.1 backup. I think I have to find out 4.3. For my device. So kindly please inform me if some one knows about .

I got this while searching online. Please tell me if it is helpful for.me.
http://androidromupdate.com/att-samsung-galaxy-s3-sgh-i747-odin-stock-firmware/
Never been to that site, but it looks OK to me. Nice find in fact! All the usual firmware sites stopped getting the AT&T firmware a while back.
Anyway, just to clarify, LK3 is 4.1.1. UCDLK3 is just the build number.
If you want to get fully updated, I suggest Odin flashing the MJB (4.3) firmware. Then flash each of the OTA's until you are updated to where you want to be. (I would fully update, but that'll be up to you.) The OTA'S are intended to be flashed from stock recovery, but there is another option if you want to try it. Mobile Odin is an app by chainfire. It does require you to be rooted, but it will flash the OTA. Read his thread here on xda to learn more. It's one of my favorite apps tbh! Once you learn how to use it it makes flashing quite easy.
So my recommendation would be this:
Flash MJB with Odin.
Root using Towelroot (easiest root ever)
Install Mobile Odin and flash the OTA'S.
I hope that clears things up a bit!

To be able to run a lollipop rom you will need to update bootloader and modem. Update them together, this is important once you reach the 4.4.2 level of bootloader and modem that you will need to run lollipop roms. Once you reach 4.4.2 you will brick your phone if the bootloader and modem versions are not the same.
Before starting to flash any of the files you need to get you up and running on lollipop, I strongly suggest you download all you need from start to finish. Store the files you will need in the upgrade process either on an external sdcard or on the root of your internal sdcard. I haven't used CWM Recovery on my SGS3 since shortly after rooting it, I have been using TWRP since then, and I don't recall all of the capabilities of CWM recovery. If the CWM version you have will not let you flash from an external sdcard you will need to store the files you will use on the root of the internal card to be able to flash them. It will be easier to do this before you start, unless you are comfortable with pushing files from a computer using adb.
BEFORE DOING ANYTHING I AM SUGGESTING read enough that you thoroughly understand what I am saying. After reading, ask questions for clarification. Be sure you have no doubts.
Decide if you intend to install a rom along with the bootloader and modem at each upgrade; or if you are going to install updating only bootloader and modem until you get them to them point that you can run a lollipop ROM. Since you said you can not do OTA updates, either way will work. Whichever you decide, you can not skip directly to the bootloader and modem you need for lollipop.
If you are installing bootloader and modems without the rom:
From the stock 4.1.1 rom and bootloader you can go straight to 4.3 bootloader and modem, skipping the 4.1.2 (MG2) version. I have personally done this with no ill consequences. After 4.3, install the first bootloader and modem version for 4.4.2, that is NE4. Lollipop will run with the NE4 bootloader. As DocHoliday stated, you can go on the the current bootloader and modem. After NE4 is NJ1. After NJ1 you come to the current bootloader and modem, which is NJ2
If you plan to install the full ROM at each step.
The page you linked to should work if all of the downloads are available. Go from 4.1.1 to 4.3 to 4.4.2 (NE4). If you want the newer versions (NJ1 or NJ2) do them in sequence, do not skip any that are mentioned. Read the instructions on your linked page carefully. If you want NJ1 and then NJ2 they can be found in threads by enewman17, as can NE4 and maybe 4.3. I didn't provide the links so that you will hopefully read the pages carefully after searching and before downloading. Be sure you understand what you are downloading to flash and how it should be used.

Flash MJB and NE4 from the site you linked to above. Then use enewman17's thread for the NJ1 and NJ2 updates. He also has NE4, in case you want to get all the OTA'S from him. (Downloads will be a lot faster) They've all been used many times. I'll try to post a direct link in a few...

Lol, I guess they thought they had to provide it somehow! It's a shame they didn't at least acknowledge enewman17 in their article there, but at least they direct linked to his thread.
Anyway, good luck! And if you have any other questions come up, let us know.
