[Q] Downgrade S3 T999 from 4.3 to 4.1.1 - T-Mobile, Samsung Galaxy SIII

I need to downgrade my Samsung Galaxy S3 T999 from 4.3 to 4.1.1 in order to unlock it.
However, when I attempt to flash with Odin 3.09, It repeatedly fails. I am using T999UVDLJC obtained from sammobile.com
My S3 was rooted, but when the flash would not work, I removed SuperSU to see if that would make the flash work. My phone is now unrooted, and the flash still will not work. Knox is removed on my phone.
Should I reroot my device? Should I downgrade to 4.1.2 first?
The Odin log:

You cannot downgrade from 4.3 firmware. If you try to force it using alternate methods it WILL brick.
This info is included in nearly every 4.3 thread btw.

So it can't be done? My device did not come with 4.3, it came with either 4.0.4 or 4.1.1.

Doesn't matter, once you update to full 4.3 you can't go back to a previous firmware, and that's the fail message you get when you try to downgrade.. You can flash a ROM based on previous firmware, but that will not help you to unlock it

I read that it is possible to flash all of 4.1.1 except the bootloader. How can I do that and will it help me unlock the device?

So as others have stated it is nearly impossible to downgrade your device after being updates to 4.3. But I have found a way to unlock the bootloader on 4.3 and install ClockWorkMod. What you need to do is use the cyanogenmod installer and it will do all the work for you, even if you dont want to use cyanogenmod. It roots, unlocks, and install CWM recovery all at once.
Go to this site for a tutorial on how to do it.

Sometimes it may reboot your phone back to the Touchwiz 4.3 software but the bootloader will still be unlocked. Once it is done installing just simply put your phone into recovery and you will be able to flash any rom you want!

I believe that if it is official 4.3 you cannot downgrade.
Is it a clone?

If it is a clone is very well disguised, and it have the same SoC (CPU, RAM, Internal Memory, etc)
And it is impossoble to downgrade from 4.3?

Ah the official stock images will have a bootloader bundled in it. So that maybe where its going wrong. If you install a custom recovery and put a custom rom (arhd19 or wanamlite3.9 are both android 412) that might be the easiest but I would only guess that yhey would work with the mk3 bootloader but it would probably burn the efuse voiding warranty.

Can the mk3 bootloader be downgraded? I wss under the impression that once upgraded to a mk bootloader you were stuck with it as theyre not downgradable

Ok Bro. All you need is to install a Firmware supported by your phone.
I had an N7100 with exact downgrade problem and was fixed by checking different Firmwares. you can install another if you like, european firmware maybe not compatible with your phone. DOWNLOAD Firmware which has size more than 1000 MBs.
Head Over to this Link and Download the Firmware with starting words "MSR",
http://forum.xda-developers.com/showthread.php?t=2571281
It will surely work.
I have tried all of these 4.1s but the MSR-N7100XXDMC3-201304291545.zip worked.

That MSR version's size is greater than a 1000MBs which means that it has all the required files, which are needed to downgrade from 4.3 to 4.1.2.
So definitely check it out and share the result with us:highfive:

Not sure but it worked for me. I had the N7100 made in korea version which is an international version. I upgraded to 4.3 chinese version. Then I wanted to downgrade to 4.1.2, I tried the chinese 4.1.2 version and two others. Which encountered some errors in flashing. Then I tried the MSR version which worked just fine.
Everytime I was flashing the 4.1.2 versions other than the MSR it incremented the binary counter by 2.

Hi everyone. Finally i could flash the note 2 :victory: but i still dont get it why i cant flash through odin
This is how i do it.
1. Flash the ClockworkMod Recovery through.
2. Flash the TWRP 2.6 Recovery.zip through CWM Recovery. (Don't know i i cant flash this recovery directly on odin
3. Flash a CyanogenMod Nightly ROM
4. Install Odin Mobile.
5. Flash the lastest official rom by Samsung for Europe.
6.Yeh I have a official rom on my mobile :victory:
Now I have one problem, when i try to make a call i cant hear the people on the other side and vice versa. I know the mic and speaker are working, if o try to make a call through skype it works perfectly!
Obs.On every ROM i have this problem, on Stock ROMs by Samsung, Europe and Chinese Version and also on CyanogenMod.
When i try to flash the European ROM on Odin it fails when try to write the modem.bin.
I can flash the Chinese ROM without any problems on Odin.
I'm using the lastest ROM JB 4.3 from Samsung
What is the problem now?
The MSR firmware zip link no longer exists?
I have Chines SN N7100 and screwed with no Google accout

Have I bricked my phone :( - Experts plz help!

Guys,
!!!!! N00B Alert - I am not an expert in what I am doing. Just following instructions from experts like you. I will try to be as technically articulate as possible !!!
I had recently (about a month ago) rooted my phone to install CM 10.2. I love CM.
In an attempt to unlock my phone I wanted to get back to stock ROM. So I googled and bumped into a way to do it from Kies (not sure if it was a good idea). I followed the instructions and boom the firmware initialization failed half way through. Now when I turn my phone on I get this error "Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again". So I tried again multiple times but it won't work.
Then I thought may be there is another way and googled and found this thread - http://forum.xda-developers.com/showthread.php?t=2186967
Followed the instructions to the word, but I see the dreaded FAIL message in ODIN.
Below is the log. (I tried twice in one stretch).

Another thing is I am not able to get to recovery mode. When I try I can only get to the Firmware error screen I mentioned above.
Any help to get out of this mess would be great!
did you make sure you had the LK3 bootloader before trying to flash stock? if so I also had Odin fail while flashing this firmware. only one that worked for me was root66 firmware. i never booted all the way in but i read that you have to uncheck "auto restart" before flashing, once it is done pull battery and boot into recovery and factory reset. if that doesn't work you can do what I did. Odin flash cwm and install a rom from your sdcard

Thanks for your response.
I didnt know I have to have the LK3 bootloader, may be I missed in the instructions.
Anyway, how do I flash Clockworkmod from Odin? if I can do that I can get back to CM 10.2 and then try paying for unlock code.

Make sure the bootloader that's currently on your phone is not from the 4.3 OTA update. If it is, you can't use Odin to restore a stock rom, you'll have to find a AT&T 4.3 ROM based on the leaked 4.3 AT&T ROM.

Yes I am on AT&T.
After I read your post about flashing CWM with ODIN I researched and found a method. I tried it and it PASSED!. Then my phone restarted and boom it booted directly into CM 10.2. Not sure how, felt a bit creepy. Then I updated to latest Nightly CM 11 build and brough back all my apps and my phone has LIFE right now. Thanks for the tip! :good:

May be it is, I updated to 4.3 thru OTA and after a few days rooted and installed CM 10.2. How do I check?
Then this should be the reason that ODIN didnt work for me. Which genuine source I should look at for a AT&T 4.3 ROM based on the leaked 4.3 AT&T ROM.

I believe if you were originally on 4.1 then you still have that bootloader. I dont think OTA updates the bootloader so you should be able to downgrade with the root66 if that is the case.

when you say "find" an AT&T 4.3 rom, I wish you could give me a link. I am working with a device that was handed to me that was on 4.3 then flashed to a t999 rom. Now I cannot get it to flash ANYTHING AT&T 4.3 (and I've looked all over), neither in odin, nor in recovery, except, oddly enough it will reflash the same t999 image. The radio (modem) also no longer works.

This is why your flash to stock failed, lucky for you. The MJB bootloader is not downgradable and if 'successful' is bad news...aka brick, requiring serious hacking if not JTAG service to repair. As far as ROM's go as long they do not attempt to change the bootloader (none i've seen do, but you never know) the worst that could happen is a 'status 7' fail in recovery and no change to your firmware, pertaining to the bootloader that is. There are any number of other reasons why something could go wrong during the process. MJB has been around long enough most customs ROM's have probably adapted their updater-script to include it. If not there are ways around this I (and several others) have documented elsewhere. My advice moving forward, make sure to educated yourself thoroughly before attempting anything that can brick your device and if you are not sure, ask first flash later.

when you say "find" an AT&T 4.3 rom, I wish you could give me a link. I am working with a device that was handed to me that was on 4.3 then flashed to a t999 rom. Now I cannot get it to flash ANYTHING AT&T 4.3 (and I've looked all over), neither in odin, nor in recovery, except, oddly enough it will reflash the same t999 image. The radio (modem) also no longer works.

I assume your can get into download mode. If that is the case, try flashing this in Odin: http://forum.xda-developers.com/showthread.php?t=2498233

I had tried to flash that via odin without success. What I was able to do to fix the issue was to flash a custom recovery via odin (TWRP). Then use the custom recovery to blind flash (no signature or md5 check) the ATT modem, and then I was able to flash the link you sent. After that it still didnt boot, so i had to reboot in TWRP, dump caches, reboot again, wait, literally like 5 minutes and it came back to life. Whew, what a day.

If you had the 4.3 bootloader on your phone, you cannot use Odin to flash a stock ROM.

Based on your Odin printout in the first post you were flashing a modified 4.1.1 kernel to install root. This should be fine if you were on either the 4.1.1 or 4.1.2 stock ROM. If you were on the 4.3 stock ROM your root attempt is probably the source of the problem.
IMPORTANT How to proceed from here depends on if you were on 4.3 or an earlier version of stock.
Also, since this forum is for AT&T and Canadian variants; I see the title of the first post says i747 - is this correct? It matters.

ok, not to jack his thread, but what if you are on the 4.3 bootloader? i didnt do what he did, but i am stuck in a similar situation. I am on the 4.3 bootloader, but i do have a custom recovery installed. problem is i get an error when i try to wipe. Ive tried flashing stock 4.3 rom via sideload in stock recovery, and modified rom though twrp. both roms install fine, but dont boot, but they do freeze in different points so i know something is being flashed. ive also tried wiping in cwm and stock. im bout ready to flash anything to this phone. oh and a nandroid restore fails after boot img flashes.

From your message, you likely were on stock 4.3. Since you are able to get into recovery and download modes, you may try a restore via custom recovery. Please see the thread below on how to install custom recovery and do a stock restore ...

Before doing anything else, boot into recovery. If you are on a stock recovery the very first line will tell you that the system recovery is 3e
If you have one of the custom recoveries it will be different. If you have one of the custom recoveries, TWRP or CWM, you can use the link Larry299 posted earlier in this thread to restore your phone. If you are on the stock recovery and the 4.3 bootloader I don't know what to suggest.

There is a chance that being rooted will prevent you from using the OTA official update. I've seen reports of people being able to update to the official 4.3 while rooted, but I've also seen reports of people not being able to update.
Before you make that update, bear in mind that the official 4.3 bootloader, its name ends in MJB, is the one that will prevent you from ever going back to an older bootloader. Some of the devs and the more experienced on here have no problem with that. Others do consider it an issue. An alternative is to install the leaked 4.3 bootloader, it's name ends in MJ2. That bootloader will allow you to downgrade to the 4.1.1 or 4.1.2 bootloaders, or so I have read. There is information about this in the development and the general forums for our device.
To muddy the waters more; if you intend to sim unlock your device without gettings codes from your carrier you need to do it from the 4.1.1 official ROM. A point you can not return to from the official 4.3 ROM, or so I've read.
I am having a huge booting issue with my Samsung Galaxy S3. Its a brand new one and I tried rooting it but it gave me this error:

Nope. Sorry. Once on 4.3 you cannot downgrade your firmware without hard bricking your device. Using a valid code is the only way now.
You might find one for fairly cheap on ebay.

Best I can say is to search ebay for sim unlock galaxy s3. I dont know of any specific sites. I think a few may have been mentioned in the unlock thread, but you'll probably just have to do a lot of reading to find them. Look for posts with links in them.

If you updated to 4.3 via OTA/Odin/Kies it doesn't matter.. If all you did was flash a 4.3 ROM while still on 4.1.2 or below bootloader its still possible to unlock unless you have a T999L then you are out of luck
And root doesn't matter for this. Should work either way.

need to reprogram as the phone stuck at Samsung Galaxy S III

My phone got crashed which can't bootup. The phone always stayed with Official release, never rooted. I am not sure which version has been upgraded to, now it stuck with Galaxy S 3 screen, only thing I know it has the SecureLinux enabled, so it must be either 4.3 or 4.4. I wanted to reprogram to the official firmware, but not sure if I reprogram to the wrong version, would that causes any problem?
Please help.
additional infomation:
at download mode:
PRODUCT nAME: SGH-T999
CUSTOM BINARY DOWNLOAD: No
CURRENT BINARY: Samsung Official
SYSTEM STATUS: Official
QUALCOM SECUREBOOT: ENABLE
Does this download menu look like 4.2?
Or it is 4.3 , I dont see warrenty flag.
Thanks.
No mention of arrange bit or Knox is the screen so the phone must be running a 4.2.2 or older rom.

The phone is T999 for T-mobile, but seems there is one time only that it had official release of 4.2.1 or 4.2.2 available. I am not sure if I should flash the 4.1.2 or 4.2.1 back. But I seem can't find the 4.2.1 or 4.2.2 firmware on line anymore.
Question is that if I try to flash 4.1.2 to the phone, would it cause any problem if it was in 4.2.1?
Thanks all, I know this probably an old issue.

It's stops when trying to flash the bootloader. Either you're using the wrong file or the phone does have a 4.3 bootloader. The download screen info provided in your post mentions nothing about warranty bit or Knox.

thanks for your response, yes the bootloader seems is 4.1.2, right now I am getting impatient about this, So I also tried to repartition it, reload the 4.1.2 bootloader. I can reload the 4.1.2 bootloader, that is only flash got success, flashed the 4.1.2 bootloader.
I have a second identical phone, So I can risk everything in the phone. Is there anyway I can just program it to 4.3?
You can flash a newer stock rom via Odin if you want to. If the bootloader is 4.1.2 and you have the correct stock rom, Odin should be able to flash the aboot.mbn file it Odin can't which tells me the file is wrong for the phone or the phone does have a 4.3 or newer bootloader.

There is possibility that the pit is wrong, I tried to load the downloaded T999-16Gb pit from download site, maybe that file is not right? Since I can flash the stock boot.img by using Odin for version 4.1.2, the bootloader must be right???, Don't know what aboot.mbn would be affected by anything else.
I am wondering if someone can provide the T999 regular 16GB pit file, the early version of T999, Thanks.
A pit file only needed if Odin cannot read the partition info from the phone and, based on the logs, a pit should not be necessary.

Boot into download mode again and let me know what it says. It the bootloader was corrupt, that would be a problem.
Just to confirm: you're using firmware from sammobile.com and you are using the original Samsung USB cable to flash the phone.

Reboot to download mode, it is saying the same.
I am trying to flash stock recovery, modem, bootloader, all stock version 4.1.2 Only it can flash 4.1.2 bootloader, the recovery and modem always fails. Also the stock rom got failed.
With the same setting I can flash my other S3 recovery without problem, so the Odin, USB cable should not be an issue.
Thanks.
Yes, this is weird. You have 2 identical phones? You can pull the pit file from the working phone and use it to flash the problematic phone.
