That's great that you got it working.
Unfortunately, you cannot downgrade your bootloader. I recommend making sur eyour bootloader mathces your modem at all times as an incompatible bootloader/modem combination could hardbrick the phone.
I recommend either flashing the modem and bootloader to the latest release using a custom recovery and then flash a custom ROM or run a custom ROM on your mjm modem/bootloader combination.
Restoring a nandroid backup should be fine as long as it does not alter the bootloader or modem.
Thanks for the lesson. I'm not at all happy about the locked bootloader, but at least I have a working phone.
The bootloader is not locked, it is not downgradeable.
The latest ROM releases for the d2lte will require you to be on a KK bootloader and modem. Something to keep in mind if you want to run the latest ROMs.
Yeah, what I meant was not being able to downgrade for a carrier unlock on 4.1.1. Although, given that the warranty on this phone is long expired and its not associated with an account in default or blacklisted I believe At&t is required to provide an unlock.

My galaxy s3 at&t SGH-I747, battery was pulled out of the mobile unexpectedly, while flashing a firmware into it. From then, it is neither turning on nor charging and not even entering into download mode or recovery mode and even un-detectable by Odin or Samsung Kies. But, as i connect it to my Computer without battery(as the battery removed from the phone) is shows connected as " Qualcomm HS-USB QD Loader 9008" and red led stay glowing for a few seconds and then gets of. Can you help me in fixing my problem. Thanq in advance.

Can you not boot into download mode manually? From a powered down state, hold the volume down+home+power. When you feel it vibrate release power but continue to volume down+home. It will boot into a warning message, press volume up to continue to download mode(Odin mode...) Hope this helps.
Tried that, but no avail, it shows the dreaded red led. Strange though that I just flashed the wrong recovery, no messy with bootloader or anything else. When connected to the pc it comes up as the Qualcomm HS-USB QD Loader something, you know, when the phone is bricked and it is recognized as a com port or modem port.
You may need to use a debrick image based on your current bootloader and modem. @mrrocketdog has frequently posted links to several. Once you are booting the debrick image from an external sdcard you can restore a stock recovery and then proceed from there. enewman17 has posted images of the stock recovery in either his NJ1 or NE4 stock image thread.
I get everything working and my phone boots now. But I want it to be able to use my SD card again. I'm got confused with the instructions given, so can anyone please explain in a bit more detail on how I can boot without the SD card?
See if the instructions in this thread will help. Modify the instructions to suit the status of your phone; instead of using a stock 4.3 ROM use a stock ROM that matches the last bootloader you had installed; probably NE4 or NJ1. Also use a newer custom recovery than is in that post.
Many many thanks, I was able to boot from my SD 16GB class 10, with the unbrick256 IMG, I was capable to flash a 4.3 stock rom, but I wasnt able to make my phone boot by itself, without the sd card, can you helpme with this please.

Try reflashing your bootloader and modem from recovery.

39thus far this method will not work for any of your 4.4.2 ota bricks if you flashed the 4.4.2 modem on the mjb bootloader, the only way to fix those bricks is with a new emmc, motherboard or a new phone. Jtag won't save you this time the phone is now a glorious paperweight.
On 4.3 it will not work if you flashed a bootloader for the wrong model(E.G. AT&T I747 bootloader on a Bell I747M)
Read ALL of the first 2 posts,there is useful information and files in post 2.
This works for BOTH AT&T I747 and the I747M The files are located at the bottom of this post in the quote there are also more instructions and files/tools to download in the 2nd post of this thread.
First and foremost I take no credit for any of the work here, other people did most of the leg work. This is a DIRECT copy of -Mr.X-'s post from here namely page 17 that is being used with his permission, I have added to it after having to actually Unbrick my phone lastnight.
Thank you to all who contributed to the things that made this thread possible. -Mr.X-, Loserskater, upndwn4par, enewman17 and all who may have contributed to their work.
So what you have done is hard bricked your I747 AT&T or your I747M by whatever means. Most likely flashing something with a bootloader. Your phone won't do anything at all. You can't get to download mode or recovery mode. Perhaps this method will fix your phone? Give it a try what else do you have to loose? You might save some money on a Jtag?
I take no responsibility for anything that comes of you using this information.
IF YOU BRICKED YOUR PHONE BY FLASHING A DIFFERENT MODELS BOOTLOADER ON IT THIS METHOD WILL NOT WORK FOR YOU. ] YOU WILL NEED A JTAG.(THAT ALSO INCLUDES WHILE TRYING TO UNBRICK USING THIS METHOD.)
Be sure to get all the way to the bottom of the first 2 posts and PLEASE read everything before doing anything.
The Debrick Files are all the way at the bottom in the qoute below by -Mr. X- The Links Are Active.
Be sure to read the second post too. If you need clarification on anything please send me a PM

Click below for the quote from where I got most of my information, do not just start doing things after you read the below quote, read the second post too.
29The 16GB SD card is going to get formatted and partitioned if you have valuable data on it do a back up of it... You have been warned.MAKE SURE YOU USE THE CORRECT FILES FOR YOUR PHONE FAILURE TO DO SO WILL RESULT IN YOUR PHONE NEEDING TO BE JTAG'ED
YOU HAVE BEEN WARNED REPEATEDLY DO NOT FLASH THE WRONG BOOTLOADERS
Requirements(carrier specific)
If you need some of the things mentioned in the requirements please click under "Tools You May Need And File Downloads For AT&T and the SGH-I747M" .
You Need to Identify Your Phone Model Correctly and download the appropriate debrick file From the quote by -Mr. X- in the post above to place on your 16GB Micro SD Card with the Win32DiskImager (available for download below).
How to put the Debrick file on your SD card
For the SGH-I747M
You need to put the Debrick SD card in the Phone, Pull and Replace the Battery, Put the Phone in download mode and flash your carrier specific 4.3 firmware (instructions and downloads Below) Via ODIN. Reboot the phone allow it to boot up, get in the phone, reboot without the debrick sd card in it, if it won't boot on its own see the link below.
If you are on AT&T
You will need to copy all of the files you are going to flash (you can download them below) onto your 1GB or larger SD card. You then Need Put your Debrick SD card in the Phone, Remove and reinstall the battery,Put the Phone in Recovery Mode (Must Be Either TWRP or CWM Instructions and TWRP Download Below), Dismount the Debrick SD card, Insert your SD card with your Bootloaders, ROM, kernel, and Modem into the Phone, Mount the SD card, Flash your files one at a time, wipe the cache and dalvik between each file, Once you are done reboot the system, You Might have to put the debrick SD back in and do another battery pull, boot up the phone, after you get in the phone reboot it without the Debrick SD card in. If it will not Boot on its own see the link below.
AFTER YOU FLASH IT MAY APPEAR THAT THE PHONE FREEZES ON THE BOOT SCREEN BE PATIENT 4.3 TAKES A LONG TIME TO BOOT THE FIRST TIME A ROM IS INSTALLED.

Sent from my SAMSUNG-SGH-I747 using xda app-developers app4Tips for Debricking!
Hey guys. I have posted much of this in enewman's thread, but thought it would be best to have it here. I have been helping members to debrick their devices in the T-Mobile S3 forums ever since the method was discovered. There are a few tips I have which may or may not have been mentioned before, and may or may not make a difference here. I believe everything should apply though because our devices are very similar to each other.
The first, and most important thing IMO, is DON'T GIVE UP! At least not right away! We have seen many people who were unable to restore their device the first time they tried. Quite a few had to run through the instructions of partitioning the sdcard several times before it finally worked. No clue as to why this happens, I just know it does happen. (I actually know from experience on that!)
We also recommend using a 16GB or 32 GB, Class 6 or better sdcard. (I personally do not recommend using some cheapo generic. Its up to you if you want or need to try with one, but they often do not actually have the advertised available storage.) (I personally always use Samsung brand sdcards from Authorized Dealers....not just for the debrick process, but for my everyday use I feel they are hard to beat.) Any name brand should be sufficient though. Just beware of all the fakes out there!
I know I've seen it mentioned that the 32GB card will not work for you guys. But it has for T999 users before. Still the 16GB is the better choice here. (I have also theorized that if you have a 32GB model, it might actually be best to try with a 32GB card if available.) In the end though, as long as it is at least 16GB, try what you have before spending money on something else. You never know, you might actually get lucky! Some manufacturers, for example, have Class 4 cards that will actually reach Class 6 r/w speeds.
I also suggest taking a look at the T-Mobile thread, stickied in Development. Some of the information there could be of use as well.
[HOWTO] UnBrick T-Mobile S III QHSUSB_DLOAD w/Video Walkthrough In particular, we recommend using a different method for partitioning your sdcard. We have found many have had little success using the Windows method. Instead, people seem to have a much higher success rate when using the Linux LiveCD or VM method. (I will post the instructions for both below). There are also links to video tutorials for those who prefer to watch it being done before trying it themselves.
For the KK bricks that have happened in the last 24 hours, I would be very surprised if this is unable to fix these devices. Especially for those who bricked by flashing the 4.4.2 modem while on 4.3 firmware. These debrick.img's include the first chunk of data from the main partition, mmcblk0. The modem is on the first partition of this, mmcblk0p1, so when you use the debrick.img, it should boot up using the modem included in that img. So if you are still on 4.3 firmware but bricked by flashing the modem, you should be able to use either the 4.3 or 4.4.2 debrick.img. Your choice. Id recommend using the 4.3 version for now, at least until we verify this is working for 4.4.2. It also means that if 4.3 does not seem to be working for you, you have a second choice to fall back on and try again. (More a psychological thing IMO, but anything that keeps you motivated to keep at it is a good thing! Having a second option can help people to feel like there is still hope if the first is not working!)
If you do end up using a 4.4.2 debrick.img, just remember you will ONLY be able to flash 4.4.2 firmware to fix the device. Just like if you were flashing normally with Odin, it will see you are booted up using 4.4.2 firmware, and it will fail the SW Rev. Check if you try to flash anything older.
So anyway, sorry for such a long post guys! Just trying to cover all the bases. I know some has probably already been discussed, but it doesn't hurt to revisit it if it has.
The following instructions will tell you how to partition your sdcard with the debrick.img using the Linux LiveCD! I just double checked and saw that this is mentioned in the OP but I missed it before. Still, incase it helps anyone I will post what we have for our instructions from T-Mobile.
What you need:
- Bricked SGH-I747/I747M
- 16GB or 32GB microSD card (all data will be erased from this sdcard)
- microSD card reader
- Linux Live Disc
- A debrick.img for your device and firmware (I can host and try to help organize all of these for each model/carrier if you guys like)
- The correct build of stock firmware for your device. (Best to match the firmware build with that of the debrick.img)
- Boot your Linux OS
- Download the debrick image (Make absolutely sure you get the correct one!!! If you are not certain, ASK!)
- Open terminal on your Linux OS
- Insert your microSD card into the reader
- Plug your microSD card reader into your computer
- Enter the following in the Terminal
Code:dmesg | tail
You should see something that mentions where it is mounted via /sdX (X = variable. Mine always said sdb.)
Code:dd if=/path_to_debrick.img of=/dev/sdX
Don't forget, X is variable representing the microSD card ignoring the partition numbers as they should be overwritten.
I had to do this a couple times for the image to actually take
- To check if the sdcard was partitioned correctly, enter this:
Code:parted /dev/sdX print
If you see an Error about the GPT table being corrupt you can type "OK" and then you will be given an option to Fix/Ignore; type "Ignore".
It should show approximately 23 partitions (IIRC)
Now that you have created your debrick sdcard, here is how you use it!
- remove the microSD card from the reader
- remove the battery, sim and external microSD card from your device
- insert your debrick microSD into your phone
- insert the battery and down your power button (at this point your phone might actually boot completely and you can recovery any software/data you want)
If you have Odin flashable firmware for your device, next do this. Otherwise, follow the instructions in your OP for using a second sdcard. - reboot into Download mode either via adb or Volume Down + Home + Power
- Once the device is booted into bootloader remove the microSD card.
- Flash your firmware via Odin like usual, and make sure you UNCHECK partition! (Should be unchecked by default already, but just in case....)
Note: If you do not remove the sdcard after booting into Download Mode, the flash from Odin will fail!
I do hope this helps some of you. I am going to try to create a stock NE4 firmware for use with Odin. If successful, you will not have to use the 2 sdcard method anymore! I hope....!
If I have gotten anything wrong, or something does not quite fit for your devices here, please let me know! And I do hope no one minds me posting this. I now know the OP mentioned using Linux, but didn't see much info on it. That and I have heard lots of folks talking about using the Windows method, which we found to be unreliable, so I figured a more detailed guide on this method might prove useful.
If I can do anything else to help, please feel free to ask! And GOOD LUCK!!!!!! :fingers-crossed:
3Amazing! Thanks you!
This worked perfectly! I almost lost hope, but this has restored my faith in Android. So, does this mean that this is the end of Custom Roms that run versions <Android 4.3? That would be a shame...Is it the Android 4.3 update that caused all of this, or just Samsung's update?(Google or Samsung) I really loved custom roms of 4.1.2 and there were some things that I was able to do there that were ruined because of the update. It wasn't quite nice for Samsung to do this to those great devs.
3OK, since we have had no confirmation of either the 80mb or 128mb debrick.img's working, I have made a few more scripts that will create new ones of different sizes.
T999_Partial_Sys_Dump_for_debrick-256.zip
This will create a 256mb image
T999_Partial_Sys_Dump_for_debrick-512.zip
This will create a 512mb image
T999_Partial_Sys_Dump_for_debrick-1580.zip
This will create a 1.58gb image
Note: Before uploading for people to test them, zip them up and it will significantly reduce the file size you have to upload.
Remember to make sure you have enough free space before running the scripts!
We will do our best to figure this out guys! I know it sucks to have such a nice paperweight....
