Downgrading?

I have Samsung Galaxy S III T999 that I had downgraded from 4.1.2 to 4.1.1 and I was able to unlock it through out by dialing and going to menu.
Every thing went ok and I was able to do it without any problem.
Few weeks after I restored my phone and some how by mistake I upgraded to 4.3
and now I can't downgraded my phone it keep giving me fail on odin.
I see so many how to downgrade and I tried it twice and keep failing without bricking my phone I was able to get back to my phone.
Is there any thing that allow me to downgrade or I have to wait for mods to come up with answers.
Thank you very much

You're lucky you didn't brick your device.. If you want to downgrade the only way to do it right now is to flash a custom recovery in Odin like twrp or cwm, and then flash a 4.1.x ROM

Is that working now? I had thought you couldn't go back once you had upgraded to 4.3

You can go back and flash any 4.1.X ROM, just don't Odin any official 4.1.X firmware coz that will downgrade your bootloader and result in a a most probable brick.
Someone please correct me if I'm wrong....

[Q] Trying to downgrade from 4.4.2 (Cyanagenmod 11) to 4.1.2 stock (T999UVDMD5)

As you'll soon discover, I'm a noob. I stupidly took the OTA update on my Samsung Galaxy S3 T-Mobile T999 from 4.1.2 to 4.3. Since doing so mine and my wife's phone (did the same thing to her also) gets in a mess after being connected to the car stereo bluetooth and prevents outgoing calls unless the phone is rebooted.
So to try to solve this, I rooted the phone and installed CM 11, so now I'm on 4.4.2. This didn't help the issue either and instead is worse at connecting to the bluetooth.
I want to get my phone back to the stock 4.1.2 rom, which I got from sammobile (PDA T999UVDMD5) or at worst back to the 4.3 stock rom (PDA T999UVUEMJC).
This morning I tried to flash T999UVDMD5_T999TMBDMD5_T999UVDMD5_HOME.tar using ODIN 307 but it failed almost instantly with an Fail! Auth message.
I also tried to flash CM 10.1 zip on my SD card using ClockworkMod Recovery v 6.0.4.5 but again it failed almost instantly (sorry I didn't take note of the error).
So now I'm back to CM 11. So any suggestions for how to get back to either of the stock roms?

If you are getting errors in both odin and cwm, it sounds like it is a root issue. In other words, it sounds like the apps are being denied access to root and therefor cannot flash. Both odin and cwm are able to generate logs so you can tell the reason for the fail. Personally, I would recommend flasing twrp recovery instead of cwm since it seems to simplify alot and is a little better for our device. Without knowing exactly why the flash is failing, i would just recommend to try and re-root the phone again.

Did you put the phone in Downloading mode before connecting to the Odin ?
Do not try to flash 4.1.2 ever. It will brick your phone.

Yes the phone was in downloading mode. I couldn't find any posts that thought that I would brick my phone for sure by downgrading so I thought I would try. Could I go back to the 4.3 Stock ROM with some degree of confidence?

Yes you can go back to 4.3 Stock.

So I'm now back to Stock 4.3 by doing a flash via Odin. I did (stupidly) try to then go back to 4.1.2 again using Odin having put the phone in USB debugging mode first but I still got the same Auth Fail error.
Thanks for all the help.

You cannot downgrade like that once you have updated to official 4.3 firmware, no offence but why would you try it even after Perseus said not to? Anyway if you want to go back to 4.1.2 so badly just download a 4.1.2 ROM and flash it in recovery

Thanks for the advice. I think I'll just quit while I'm only slightly behind now and remain on 4.3 Stock. I appreciate everyone's help and suggestions.

Downgrade from CM11 4.4.2 to 4.3 on I747
I went from 4.3 stock to CM11 on my i747 but i didnt like the update. So i am trying to go back to 4.3 however whenever i try to install the 4.3 zip file thru twrp or CWM, it fails. As far as i know there is no odin file for going back. I tried to flash rogers 4.3 file through odin (thinking i would flash at&t modem later) but that also failed.
I would appreciate any help on how to install 4.3 once 4.4.2 has been installed on an i747

You seriously need to do some reading

For One, you are on the wrong forum. This is for T-Mobile's S3 not AT&T. Second, Like @passtheknowledge said, you really need to do significant research and reading here on XDA.

Please Read through this Thread. For Future Reference, all Odin Files for S3 in general are looked up by unique Keyword Root66. That thread is the right place for you to post errors or issues. If there's no 4.3 image for your phone there, you can post a request as well.
For your immediate Problem, there is a an alternate ATT StockMod Rom by @saranhai Please see this thread. Pay particular attention to the mandatory requirement of flashing a particular modem beforehand.

Tmobile Odin Fail

Hello! I am new to this forum but I am in a little fickle.
I have the Samsung Note 2 TMOBILE and couple weeks ago, I updated to 4.3 through regular OTA. I then rooted and flashed Cyanogenmod 11 and thus, voided my Samsung Knox Warranty bugger thing. I then attempted to go back to stock by flashing stock 4.1.1 through Odin and it worked! I tried to do OTA update again but I realized that the Samsung Knox Void kept me from reaching update services... So I was stuck at 4.1.1 Stock. From there, I was able to flash other custom roms and everything worked.
However, this is a problem for me. The 4.1.2 update from Tmobile was what enabled LTE on my note 2. So right now, I have the old baseband(?) that does not allow LTE. I even attempted to flash a non-knox 4.1.2 (which allowed LTE) through Odin and everything worked until the last second, where Odin is supposed to flash PASS..... It flashed FAIL and I was unable to update my baseband(?).
I was wondering if there is another way to enable LTE by updating to 4.1.2 in any way? Or is this completely unable due to the Samsung Knox?
Thank you in advance.

Thank you! Before I mess anything up, I just have a couple more questions. Do I just have to find the 4.1.2 modem? Or even 4.3? I already have CWM and am rimming cm 11 4.4.2. Does this mean I must downgrade first before I attempt to flash a modem?

Official 4.4.2 --> Reinstallation

Dear Experts, Need your help.
Look at the attached pictures.
I successfully flashed official 4.4.2 (M919UVUFNB4) through OTA
Since then I had google play store issues. "Could not communicate with google severs" for more than 2 days.
So I decided to get the stock 4.4.2 reinstalled. But it would need Stock 4.3 to allow OTA 4.4.2 to pop.
* So tried to go back to stock 4.3 using ODIN. This is where things got messed up.
* ODIN downgrade failed. Could not boot
* So I flashed OUDHS-Recovery-jfltetmo-1.0.3.3.tar using ODIN. Successfully flashed and booted.
* Installed CWM recovery 6.0.4.4
* Flashed "jfltetmo_M919UVUEMK2_Stock_Deodexed.zip" successfully and booted.
* Tried to go back to stock 4.3. Failed again.
Right now my phone is working without any issues with deodexed 4.3. Look at the attached pictures.
Let me know how can I get back to Stock 4.3
or
how can I update my phone to Stock 4.4.2
Appreciate your help!

Wrong section man but you can't update to stock 4.4.2 w/o the .tar (unreleased atm) and you can't go back to stock 4.3 because of Knox. All you can do is flash a 4.4.2 custom ROM and wait for the .tar for 4.4.2 to be released.

You can try this: http://forum.xda-developers.com/showthread.php?t=2679913. It's a completely stock flashable zip.
I will say that I haven't tested it yet (will do so later), and the Dev warns that things might break. So you have been warned. But if you're already on the 4.4 boot loader from the OTA update, its worth a shot. Just make a nandroid so that if you get any errors you can go back to what you have now.

There is a way to get a fresh install of the 4.4 NB4 OTA. We've been using the process for the I337 for a while now since AT&T stopped releasing the full tar files. I recently picked up a used M919 for the unlocked bootloader and have been able to follow the same procedure to get the fresh re-install of NB4.
I will put together the needed files and post a link but all thats needed is to place the OTA zip in your ext sd card and then flash the MK2 system, modem, recovery, and cache images using odin. The phone will not boot at this point but you then go into recovery and flash the OTA zip from there.

[Q] Won't boot after return to stock via ODIN attempt

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!
