Hi,
I bricked my phone by accidentally downgrading my boot-loader. I was running Quantum Rom which had previously required me to upgrade my bootloader. Since I was encountering some issues with the rom, I decided I wanted to flash back to stock. Foolishly, I used Odin to flash stock firmware which involved a bootloader downgrade as well. This resulted in a bricked phone . I can still boot into download mode but I am unsure on how to unbrick the phone since Odin doesn't work. Any ideas?
Thanks!

If you are on the i747 and not an i747M, this should help you fix your phone, AT&T I747 UCUEMJB Stock Restore. It is done from a custom recovery.

So I'm a retard and I installed the MK3 boot loader on my AT&T GS3 and accidentally deleted the OS. I can still boot into the recovery and download mode. I can't flash anything through Odin since the boot loader doesn't let me. Is there a way to fix this or is my phone completely bricked? If there is a way to fix this, please tell me how. Thanks.

It's not a complete brick if you are able to boot into download and recovery modes. Your best option would be to attempt to restore your OS to as near stock as possible. I'm not sure which one you mean by the MK3 boot loader? There is no MK3 for any the GS3 variants or did you mean MK5 which is for the Canadian variant? You may try the method posted in the thread below to attempt a restore to stock 4.3 (I'm presuming you were on 4.3 prior to the firmware failure) ...

If you don't have custom recovery installed, you would need to flash this via Odin. You may not be able to install ROMs via Odin but you should be able to flash custom recovery if you can get to download mode.

Thanks for responding. My bad. I have the MJ2 bootloader.

With the MJ2, you shouldn't have problems installing new (compatible) firmware as this a modified version of MJB only. Your safest bet would be to go completely stock and follow the procedure outlined in the thread I earlier forwarded.
So, I'm not a complete noob to flashing roms/rooting devices. I flashed cm 11 to my s3, and decided I wanted to go back to stock via Odin. For some reason when I tried to turn on my device it was still showing the cm 11 splash screen and wouldn't proceed any further. It isn't technically bricked. I guess this would be classified as a boot loop to the nth degree. I tired to boot in recovery mode and wipe the cache partition and all user data to the same cm 11 robot taunting me. When I tried the process (flashing stock vi Odin) again to possibly fix whatever might have been a miss, I got the error message on the download screen "secure check fail: sb12." On the download mode screen it also says I am running the official system rom. I don't know what steps I need to take from here to get my phone to actually boot via the stock rom. Has anybody else had this issue or similar? Any help in resolving this would be greatly appreciated.
Is your phone a i747? If you are you running a stock 4.3 bootloader on your i747, you can't use Odin to flash back to stock unless the ROM was specifically designed to be flashed in Odin.
What is shown on the screen in download mode?

I was under the impression the rom I was attempting to flash was indeed intended for Odin. It is the SGH-I747.
The download screen states,
Product Name: SGH-I747
Custom Binary: Custom
System Status: Official
Qualcom Secure Boot: Enable
Warranty Bit: 1
Bootloader AP SWERV: 2
Here is an added bit of fun, in the midst of the process I accidentally checked "Nand erase all," in Odin at one point.
Based on the information provided, your phone is running a stock ATT 4.3 bootloader. The CM11 splash screen is still showing up because the flash did not actually happen. You're lucky your phone was not bricked in the process of using Odin. I recommend not using Odin to flash a ROM that tries to alter the bootloader.
I recommend flashing a custom recovery such as Philz Touch in Odin and flashing a different KK ROM such as Valudis.

My next question would be how can I move the zip files I download to the internal storage of my phone to flash them through Philz Touch?

I did. It said the the device couldn't be updated, or something to that effect.
Kies will not work without a stock recovery or a rooted phone from my experience.
I would be surprised if kies can restore your phone as ATT never released a full 4.3 stock ROM. ATT only made 4.3 available via an OTA update.

I don't know about AT&T, but I'm on Telus in Canada and I used kies to revert back to stock 4.3 with CWM recovery and phone rooted, and it worked no problem.

So, I know there is a "thanks," button but I feel like that would be a little too informal for how much I appreciate your help! I downloaded ADB to move the rom (I went with AOKP because it was the first one that worked) to my phone, flashed it using TWRP and...BAM! We are back in business. Thanks for the direction, I thought I had a nice, new, shiny brick on my hands for about two days.

Canadian carriers use the i747m while att users get the i747.
The Canadian carriers did release a full 4.3 ROM unlike att who did not.
Was trying to get the phone back to stock so I can upgrade. I followed the instructions on the How to Return a Device Back to Stock thread, downloaded the stock TAR, rebooted and tried to boot into recovery but it would not let me. I then tried to boot into the device as normal and now I have a screen with the message Firmware upgrade encountered an issue, Please select recovery mode in Kies & try again. Any suggestions? I downloaded and tried but cannot connect via Kies 2.6.. I can still get into the device via ODIN. Suggestions?
What firmware did you use to flash? Flash NH7 if you haven't
A little back-story and a possible solution.

I've never updated my S4 past the MDL firmware. I encountered this problem a few months back when I wanted to revert back to 100% stock MDL. I had updated my baseband/modem though to NB4, yet still obviously had the MDL bootloader. I was scared to death that I had bricked my phone because nothing I did would let me boot past that screen. I couldn't get to recovery, normal boot, nothing... the phone would just automatically go to that screen: Firmware upgrade encountered an issue.
What I did was simply revert my baseband/modem back to MDL. Once that was done successfully I was able to flash the MDL firmware again and booted right up. If this might be your issue, you will have to know which baseband/modem you were using and which bootloader version you were running before you attempted to flash stock. It should go without saying that the main idea here is to have your baseband and bootloader versions match before flashing the firmware in Odin.
Seems a little odd to me as the stock Odin-flashable firmware includes the modems and all... I'm just passing along what worked for me when I had that problem.

I'll repost from another hoping this explains it as it is the only thing I can think of.. but it worked.
TLDR: installed stock TAR not stock TMO TAR, updated (stupid me) to 4.3, wrong baseband and recovery did not go back to stock using the stock TAR and the Philz Touch recovery would not have flown to return the phone. I figured it out with some help though!
Thank you, that was it. I returned it to stock after following the instructions in the how-to thread but something happened and it boned the recovery where it would reboot into the device every time. Being they need to inspect the phone and in my case they wiped it in front of me when I turned it in it had to be fixed. The device received the updates from TMO and stupid of me I installed them so it was now 4.3 hence the reason I could not install the stock 4.2 anymore. I found the stock firmware you mentioned above and installed it and it fixed it but tripped the counter. I installed the updates from TMO and it was enough to pass inspection. I was able to go into recovery at the store, show the clerk while he was dicking around with the paperwork for the Note I was about to buy. I reached over, showed him "look here it is in recovery and here is wipe data factory reset okay?" and wiped it. He muttered okay thanks or something like that and we were golden. Heck if he could have read the counter anyways it is so flipping tiny.
Thanks for the suggestions!
SGH-I747M rooted, but still original rom
Carrier - Rogers
Ready to ditch my original Samsung/Rogers rom and flash a new one
Can someone please refer me to their choices
Hopefully no cellular/modem problem and no camera and sd card problems
Thanks in advance, any other tips will be appreciated
Research a bit,
first unlock for free from Rogers if you're still on 4.1.1. After you've moved up it costs.
Then update bootloader, I'm no expert, research.
I would highly recommend. Matrixzones L with a twist. It's for our phone specifically.
Works awesomely for me.
Sips at the battery. Every thing works fine for me, and I've tried a few
The safest way to move to a new ROM is to confirm the bootloader and modem currently installed on your phone. Once you know that, you can then determine if you can unlock your phone using the free method and which ROMs will work with the bootloader that is currently on your phone.
Okay, getting closer and confident
Device type - d2can
Bootloader/Baseband/PDA- I747MVLDLK4
Modem board- MSM8960
Will use EZ-Ulock to unlock the bootloader
Phone was rooted long tome ago
CWM-based Recovery v5.5.0.4
After a few more search, ill go with the suggestion of using matrixzone
Not sure if I still need to update my bootloader
Thanks for any more tips
well my confident just drop down
i have 4.1.1firmware so i installed the ez-unlock app to unlock my bootloader
i thought everything went well - "that was easy", but now it wont turn on
hopefully someone here can help
Have you tried the holding down volume up, home and power buttons at same time to get into recovery, then restore back up?

I'm no expert but I understand you have to have original Samsung firmware running on phone then rogers has to do it for free, chime in anyone who knows more. I'm at knowledge threshold.
The bootloader on the i747m and i747 was never locked and using the bootloader unlock app bricked your phone. You will need to unbrick the phone using the method described in the unbrick thread or have the phone repaired via jtag service.
http://forum.xda-developers.com/showthread.php?t=2549068
With the i747m or i747, you could have flashed a custom recovery and then a custom ROM.

What error did you get in Odin? Sounds like you tried to flash an older ROM over your existing ROM. Try downloading and flashing the latest ROM from sammobile.com.
what is latest rom i can download and install - my rom was 4.1.1 before i messed up badly
well i just tried the next up - 4.1.2 Rogers Image and still Fail! (auth)
I will now try to latest from SamMobile - 4.4.2 and hopefully this work
well sucess - download the latest sammobile 4.4.2 and used Odin to install.
after 30mins my phones back to normal
thanks for all the help - now i'm more confident
now i will try to root / install cwm / and continue with matrixzone w/ a twist - hope to have a better result
No need to root first. You can install custom recovery and flash a rom.
can someone please provide insight on how to root my phone
i'm seeing a instruction to use Odin and CF-Auto-Root.tar
is this safe - since now im on 4.4.2
thanks again
Try installing a custom recovery and flash SuperSU from recovery.
So I ran into some issues with flashing an android 6.0 ROM (slim6) on my AT&T Galaxy S3 I747 and was wondering if its safe to revert back to the stock firmware using odin and start over from scratch. The stock firmware being Jellybean 4.1.1. I have it rooted and CWM installed. I havent done anything with the bootloader (unless flashing a new cutom ROM messes with that.) As of now I have access to both download mode and recovery menus. The issues I have is an error message after the phone boots up that says "Unfortunately, Setup Wizard has stopped" and I cannot get past. Also, since I use this phone with T-mobile, would I have to unlock it again if I were to revert to stock?
Once the phone is sim unlocked, it should remain unlocked after flashing ROMs, bootloaders, and modems.
You cannot flash a stock rom via Odin unless the bootloader on the phone is 4.2.2 or older.
