[Q] Galaxy S3 downgrade from android 4.3 to 4.1.2 - T-Mobile, Samsung Galaxy SIII

I have a T-Mobile Samsung Galaxy S3 (SGH-T999) and I made the mistake of allowing an upgrade??? to android 4.3 which has been very unstable for me. T-Mobile, Samsung, and Google all say that there are no updates to 4.3 and I can’t downgrade, so basically I’m out of luck.
Can I downgrade 4.3 to 4.1.2 without bricking my phone and hopefully without voiding my warranty? If so, please give me some instructions. I downloaded Odin 3.07 and firmware: root66_TMO_T999UVDMD5.7z. Thanks a million.

I don't think it's possible to downgrade anymore due to Knox. There was a thread talking about it
Maybe you should check it out.

if you flash the root66 of the md5 firmware via odin after you have already upgraded to 4.3 you will HARD BRICK your phone. Taking the 4.3 ota updates your bootloader and flashing anything other than 4.3 in odin will wreck your life.
You need to download the root66mjc firmware here:
http://www.androidfilehost.com/?fid=23212708291682181
And flash it in odin. Then from there install a custom recovery and download a rom of your choosing and the compatible modem. I recommend you download the md5 modem. Then you're gonna wanna boot into recovery and flash the rom and the modem only (kernels are ok of course) JUST NO BOOTLOADERS. I don't even know if you can do that in recovery but trying to mess with the new BL will brick your face I mean phone.

full steps?
so does anyone have any full list of steps and links on where to get the modems and all to downgrade 4.3 with knox down to 4.1.2

I was referring to the 3 persons who responded to the OP's question similar to yours. @jtl_777's response is pointing to the 4.3 Firmware.

Its more implied in this thread than stated matter of factly. This thread is several months old, and I know your question has been asked countless times in many different threads, much more recently than in this one.
I suggest you read the stickies in each section. Just by doing that you will find all firmware and modems and more. You will also find that the answer is no, you cannot downgrade your full firmware from 4.3. And you never will be able to.
If your having problems I suggest flashing the latest 4.3 build via Odin, then factory resetting. Start over clean with minimal restoring of backups (only the essentials).
Every time an update comes out there are people who have problems. The majority are solved by doing what I just said because most bugs are caused by using old data created by old apps on the new build.
Even if you could downgrade, chances are youd run into even more issues and still have to factory reset.

thanks but I read online and some youtube videos showing that people have gone from 4.3 back to 4.1.2, just trying to make the phone the way it was before any updates were done and wondering if anyone knows the proper steps without bricking the phone.

They probably just flashed a rom. It is simply not possible to downgrade the firmware though.

so i found this post: http://forum.xda-developers.com/showpost.php?p=48758977&postcount=1412 and i have the same case as Christopher4tw with a stock 4.3 T999UVUEMJC and just want to get back to T999UVDMD5 so its running the 4.1.2 version of android
so do i just download the below file, extract and flash via odin then do a wipe via recovery? If not can you please explain how to go about this so i can have 4.1.2 running on the phone

great thanks so much for your help, can I flash the recovery via odin mobile app or is it safer to do it via pc?

Safer via PC.
It is possible via Mobile Odin. But that's one of the partitions I don't want to mess with when Phone is Booted/

If you know how to use Mobile Odin then it should be fine. I agree that its better to use pc odin if youre not familiar with Mobile Odin. However, it actually doesnt flash the recovery while booted. It flashes the flash kernel which is MO's temp recovery. It then boots to this and flashes. (So, perseus is right in that regard. But I personally love Mobile Odin and find it extremely useful and consider it safe unless you are brand new to all of this).
In fact Mobile Odin is another way you can flash 4.1.2. Itll flash the firmware, but only the system, kernel, recovery and modem. (I didnt bring this up previously because I didnt want to confuse, or go too far too fast).
If youre thinking about flashing recovery via MO, though, you can also instead just flash the rom you found. No need to flash the recovery unless you just want to. Put the rom in the update.zip slot and itll flash just fine.
If any of this is confusing, just stick with the original plan for now. The rest will come easy if you dont rush things.
One more thing, while you can usually update stock without wiping, you may find you have to factory reset after downgrading as the old system was not built for using data created on a new version.

thanks for all the help.. had to do the wipe since it kept showing the samsung logo but after that it booted just fine.

I have tried so many times to downgrade to 4.1.2 using odin but I havent be able to. I always get an error message

[Q] Tmobile update on stock rooted rom

Can I let the Tmobile Update download and flash if I am rooted on the stock ROM and have Clockwork recovery? I would use ota root keeper to disable root also before the update.
Sent from my SGH-T999 using Tapatalk 2
When it is rooted even if you try to use the OTA update it won't let you, while rooted, you could alternatively flash the update via ODIN w/ root support. Or try some of the sweet ROMs available , the reason I switched to a custom ROM because I was going to have to erase my phone anyway if I wanted to update, so I thought why not just try a custom ROM?
I use LiquidSmoothRC7, but if you want a more stock feel with touchwiz you can try Wicked, Wicked stays true to the "official stock ROMs" and just adds roots and tweaks the ROM to make it as stable as possible
If you are rooted, with a custom recovery, there is absolutely no reason for you to be playing around with Odin or OTAs... your updates are available in the development section

Actually there is. There are 10 partitions rewritten with the Odin and OTA update. Only 5 get rewritten if you flash via custom recovery, so you don't get the full update.

go to doc's thread, flash his firmware update, reboot, then flash whatever JB ROM you desire. there is absolutely no need to ODIN your phone with the OTA fw, resetting your device completely. you just need to make sure you flash the latest firmware first before you flash a ROM that is based off the latest OTA

Some of those 10 partitions that are getting rewritten are... for one, your recovery... so that makes 9 actually...
My point is, and I'm not trying to be argumentative in any way, merely objective, is that unless it is reformatting the ext4 partition to new file structure (for example) there should be no need to do this. I suppose I would ask somebody to define in depth "rewritten" and how exactly this is being done and why. Every single update we have had since the release of this device I have not once updated my own device with odin merely to put it back to stock. And I have run into zero issues. Seems like a waste of time to me unless there is something highly critical being restructured entirely. In the end, its all the same disk, and disk size for any given partition.

If you are on LH2, with that same baseband, I would go ahead and update your baseband via docs packaged update in his thread, and just reboot, then move on to the jelly bean updates. Do a factory reset through recovery before you flash the JB ROM tho since you are coming from a completely different version of android.

If you want to avoid all the weird miscellaneous problems listed in the Q&A forum, update using Odin and the rooted rom in Docs' thread. If you choose not to use Odin do not be surprised if odd things happen.
Just stating my experience, I was rooted stock ics and ran the ota update. I was able to update, keep root and ran stock jelly bean without any problems at all.
Now I am running frosty jelly and still no problems at all. I am not saying for you to do it (dont want anyone blaming me) just stating that it can be done. Do whats most comfortable for you.

Again looking for some technical clarity here. Haven't had a single issue myself. With anything. And I have not factory odined my device once since I got it. It is not critical to do this, otherwise I would be suffering from "weird miscellaneous problems"
Hopin doc can jump in here and set me straight if I am wrong, but it seems to me you will be fine just updating your radios and then moving to the latest build (4.1.1) as long as you clear data before flashing your ROM of choice

You could very well be correct. Not trying to debate you.
but....I am seeing thread after thread of issues. Based on experience I suggest using the full proof method. I have updated many phones using many different methods and never have problems, but apparently many have had issues.
I also hope Doc chimes in on this thread.

If I understand the process correctly
ODIN flashes the entire phone OS like the kernel, Rom, baseband, etc
Using recovery to flash only updates the Rom,recovery,boot,kernel

The file used to flash with Odin is much larger because it is a complete rom. The OTA is a patch that attempts to patch and modify existing files.
I basically said that on the last post not the one you quoted

Help me flash a T-Mobile S3

This will be my first time flashing on a T-Mobile phone. My friends have an S3 stock right now. They want the latest rooted stock ROM. I don't know where to start. Do I need to unlock the bootloader? Is there an Odin executable file that will flash the complete ROM? All I see are zips for full stock rooted which I would have to use CWM or TWRP. If that's the only way, I suppose I would have to root and install a recovery to install the latest rooted stock ROM. Any help is appreciated and thanks!

Read up on how to root your device first, I used an ODIN file which rooted my device. I then installed Rom Manager to get the latest CWM recovery. You can also use Goo Manager if you want TWRP. After you get a recovery and root, you are pretty much set for any ROM you'd like to flash.

Start by flashing the root66 firmware in Odin from that thread. Everything you need should be there. Including how to use Odin. Just gotta be willing to put the time into reading. Don't take shortcuts until you are very comfortable with the process. Even then, be careful doing so.

As Doc said, read, i am new here and honestly i rooted my phone easily without any problems, it was my first time owning an android, first time trying to root one and how i got through? I read, and i mean i spent hours reading until i feel confident that i understand and everything is covered in "rooting". I plan to do this in steps.
I "know" how to root so if someone say, hey root my phone, i can do that. Other things like flashing new roms etc? I'm reading up now so in a few days i will be trying out new roms and all those other weird name things that these guys do!
You just have to plan on taking your time, Rome (roms either lol) wasn't built in a day and you weren't either, it took you nine months (i would assume)
PS Its fun once you get the hang of it! Take your time...

Thanks for the replies! I didn't stated it before but I am very familiar with rooted and flashing ROMS though not on T-Mobile that's why I was asking. I have previously flashed on Sprint and now on Verizon, so I have rooted and flashed custom ROMS a lot. Anyways my friends finally got some free time to come around to flash their phones tomorrow. I am going to start by doing a factory reset and apply the appropriate root66 - PreRooted Firmware that matches the currently installed ROM. Then I am going to install TWRP via GooManager and go from there. I don't know if their phones are still on 4.1.1, but if so, I am updating them to 4.1.2 using the following:
UVDLJC - UVDMD5
Type: Official
Version: 4.1.2 JB
Date: May 13, 2013
http://forum.xda-developers.com/showthread.php?t=1949687
Then I am not sure yet, but I will have to update the Baseband Modem with this file:
Baseband: UVMD5

OS: JB 4.1.2

They want latest Stock Rom, but Rooted, so please correct me if I am wrong with what I plan to do, thanks!
dja2k
Just flash the root66 UVDMD5 firmware. Then you're on the latest stock, already rooted. Ill never recommend using an ota if there's another option available.
And you won't need to update the modem. It may not be the best one for you anyway. Just because its the latest released, doesn't mean anything when it comes to modems.
Sent from my SGH-T999 using xda premium
Oh my bad, I didn't see that the firmware is the full ROM. Ok but the modems are interchangeable, so I can flash it and if it doesn't work better, I can go back to the one it had.
dja2k
Yup. And in case you don't know, the firmware includes the modem too. We have a lot to try, so if you're not hapoy with one try the next.

Help Updating (Sorry for noob question)

hey guys have been out of the modding life for a long time now since HTC Amaze came out on market and ive had nexus' (galaxy nexus) since then. i had a quick question. my sister passed down to me a S3 T-Mobile one. its on 4.1.1 and i had at the time put in CWM long time ago as i was gonna flash custom roms but never got around to it (i did this with the help of a youtube video.) now i have this device the Volume UP button doesnt work which is essential to go into download mode... how would i go about updating this to the latest 4.3 Firmware? if there are any detailed steps id really appreciate them. Sorry i know it sucks to get noob posts like these but i have done a bit of research and i cant seem to ask the right questions on google! thanks
btw just for though im switching from nexus 4 to s3 just cause i dont need the power from the n4 and i just want the s3 screen
so i think i found the piece i think its here: http://www.ebay.ca/itm/T-Mobile-Gal...cement_Parts_Tools&hash=item4d14d4fdbd&_uhb=1
is there a demo on how to do it or should i take it to Pacific Mall and get someone to do it? how much would it cost anyways?
You only need volume up to enter recovery.. volume down is for download mode.. anyway there are apps that can get you to download or recovery mode as long as you are rooted.. you could do that meanwhile or just wait till you fix the button.. really all you have to do is flash a 4.3 rom and modem in recovery, no need to update the whole firmware
Sent from my SGH-M919 using Tapatalk
Being on 4.1.1, itd probably be a good idea to update the firmware. Thats just my opinion though.
You can root without volume up working, and or flash roms like serio said.
As for fixing it though, if you are good working on electronics and have good manual dexterity, you could probably do this yourself. But the advantage of taking it to a shop is if they screw it up theyd probably have to replace or reimburse you for it.

what if i want to flash cyanogenmod11? is there any step by step? i dont want to brick this phone
do i have to update baseband?
First thing is to get rooted. Easiest way is to flash the root66 firmware via odin. Now decide if you want to use cwm/twrp recovery, or Mobile Odin to flash your rom.
If you want to use recovery, use goo manager or rom manager from the store to install the recovery. Then from the app choose reboot recovery and flash your rom. Factory reset after and reboot. Thats it.
You may need to update your firmware to at least 4.1.2. I think cm had issues running on older firmware.

isnt cm going to be 4.4.2? hwo do i update ? im fully rooted and running CWM 6.0.4.5 Touch ^^ dont know about TWRP but ive been using CWM for the longest time before so i trust it
If you want to skip updating firmware, just flash the rom from cwm. If it errors out youll need to update to at least 4.1.2 (official or root66) via Odin.

Go to the firmware thread stickies in development (and linked in my Sig). Download the 4.1.2 firmware (or 4.3 if you choose, up to you), and flash using PC Odin.
Mobile Odin, while awesome in its own right, cannot update your boot loader and other important parts of the firmware needed by CM.

[Q] T999v - TWRP (2.7.1.0 or older) “NO OS Found”

Hi All,
I have S3 T999v – Wind variant running on stock 4.4.2 , overall I hate this kitkat experience...
My issue is whenever I try to flash custom recovery TWRP (2.7.1.0 or older), it installs but when I try to take backup it shows nothing to take backup of (no System , no EFS etc....). When I try rebooting it gives error “NO OS Found” I am able to proceed anyways and it starts up phone fine.
Can anyone tell me what could be the issue here??? I wanna downgarde to either stock 4.3 or to install custom liquid smooth 4.4.4. but would prefer to take a back up just in case.
BTW my phone is rooted , rooted it with towel root.
Also can I flash T999 (t-mobile) based recoveries onto my T999v ?
Would appreciate your help :good:.
Thanks
I recommend using d2tmo recoveries over d2can. More roms will be flashable. And you can use any rom here in our forums.
For now, try using either cwm or philz recovery. Youre experiencing a known issue that I believe is related to the hardware revision. I keep hoping to attempt a fix, but just havent had time yet. But for now, one of the other recoveries should work for you.

No, you cannot downgrade firmware. Just try what doc said

Thanks buddy, yup CWM worked :good:
but why cant we downgrade to 4.3, i though it was that one cannot downgrade lower than 4.3 i.e. 4.2. in not possible now!
Knox. They prevent any downgrading to protect against tampering with Knox secure containers. You can't downgrade anymore, period. Anything beyond 4.3 or with Knox will be this way from now on.

Yeah just like doc said, if you're on 4.3 firmware you can't downgrade firmware to 4.1.2, or if you're on 4.4.2 you can't downgrade to 4.3 or 4.1.2.. Anything lower than your current firmware is a no.. You can only flash equal or newer firmware

[Q] need at&t s3 4.1 debrick image

plz any one help me
.i tried 4.3 at&t s3 debrick image by using this thread http://forum.xda-developers.com/showthread.php?t=2660566
.but it didn't help me out
I suggest using our debrick thread here in this same section.
http://forum.xda-developers.com/showthread.php?t=2549068
Not all bricks are fixable, and if you've ever updated to 4.3 or above, older images will not work.
If you need further help please be as detailed as possible about the device and what happened.
Good Luck!
(If you determine you really do need the 4.1.1 debrick.img and can't find it let me know.)

i detailed what i did to my at&t Samsung galaxy s3 i747
.my at&t s3 i747 running 4.1.1
.i tried to put 4.3 through Odin(its almost done the work)
.but after finishing work my phone gets automatically rebooted(while android updating)
.and failed by turned off(total dead)
that's what happened.i tried lot of debrick images from 4.1.1 -4.3 of at&t s3 i747
.........but when i used connecting my phone to charger without battery,the red LED blinked
So Odin said PASS and it rebooted? That part is normal. And are you saying that after it rebooted, it said Android is Updating and then it just died?
If i am reading that correctly, I don't know that this debrick method will work for you. It leads me to suspect that there is a deeper hardware problem, possibly with the memory I'm guessing.
It's still worth a try though. From what you described, you are going to need the 4.3 debrick.img though. The 4.1.1 image won't work after flashing 4.3.

Ok. So you are able to boot download mode, correct? Let's get it booting on its own for now, we can worry about updating after.
Download the MJB 4.3 firmware from here:
http://forum.xda-developers.com/showthread.php?t=2722660
Extract the .tar.md5 file
Remove the sdcard
Flash the MJB firmware in Odin
Reboot.
If it hangs during boot up, reboot into recovery and factory reset. (This will wipe internal sd unless you flash a custom recovery first).
At this point you should be back up and running normally. Let me know how it goes and Good Luck!

dude i put stock s3 4.3 bootloader.
and its working fine without the debrick image SDcard...
what should i have to do after that to get a 4.4.2?
That's awesome news! Glad to hear it's fixed!
You have a couple of options to update from here. If you are with AT&T, got to Software Update in the About Device menu. Might take a day for the ota to become available.
Alternatively, enewman17 has two threads in the General section for updating from MJB to NE4. One will fully update everything to 4.4.2. The other will only update your base firmware, leaving your rom, kernel and recovery as is.
I recommend reading both OP'S and the last few pages of each thread. Then pick which one you want to use.
If you have rooted or flashed anything since debricking your phone, I highly recommend using the one that only updates the base firmware.
If you are still 100% pure stock, either one should work fine. (I do still prefer the base firmware update personally, but either should work ok.)
If you have any questions about them, feel free to ask. And congrats on fixing your device!
