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.

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

I stayed on 4.0.4 with the base of UVLH2 and just clean installed JB roms so should I update the base? Or is it already updated?

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

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
From Build: UVDMD5
OS: JB 4.1.2
http://forum.xda-developers.com/showthread.php?t=1880987
Release Date: May. 13, 2013
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.

Which is the current stable released 4.3 ROM that I can flash on top of the 4.1.2 stock ROM I flashed previously? There are several ROM's and have warnings like this one below so I can't figure which one to flash.

After reading many of the various threads posted on this forum, I understand the desire and need to limit useless posts. If this happens to be one, please delete it. I have been rooting phones and using info from this site for several years and early on decided not to waste XDA servers space.
So having said that, I seem to not be alone in having returned to stock and getting the Knox update. I have (thanks to the help of some folks on these forums) been able to unbrick and return to a stock MK3, mostly de-Knoxed system on my Sprint GS3. Where can I find a thread that lists my current options for using custom Roms safely? Perhaps a sticky thread specifically addressing this issue?
Thanks,
Carl
If you have taken the 4.3 ota you can only flash 4.3 touchwiz roms and the recent aosp based roms
Sent from my SPH-L710 using Tapatalk
That really is the only restriction now. You have to stay on 4.3 ROMs. There are some good ones out there. My current favorite is MOAR 7.1
Not true. You can flash any ROM you like. You simply cannot downgrade or change the boot loader. As long as you do not try to ODIN an earlier stock .tar, you will be safe. android version is irrelevant.

@eletendre84 is absolutely correct; bootloader does not equal modem does not equal Android build number. Knox is only scared of one thing, and that is being replaced by a non-Knox bootloader. Period.
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

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.

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
I am pretty overwhelmed by all the searching I have been doing on the different basebands and modem upgrades.. Most people seem to want to downgrade in the posts I have been finding.
I have not ran stock TouchWiz for over a year, I believe I was still on 4.1.1 or 4.1.2 back then.
Currently, I am running a custom ROM (GZ Rom Validus or Spirit Rom) which are both on 4.4.4. My current Baseband and Bootloader are LK3.
It was suggested in on of the G+ Communities I update my BB and BL, is NE4 the current one? Should I still go about this? and if so, Which guide should I follow? I have the current CWM Recovery installed. Do I use enewman's guide from the General Discussion? Do I need to install the full stock 4.4.2 firmware or can I just flash the modems and bootloader?
I have never installed 4.3 OTA update, have never had Knox on my phone.
Is knox that big of a deal? Does it make things that much tougher to get around things?
Sorry, if this has been covered before, and I have searched the forums and done a bit of reading, but I think I may have read too much and just confused myself further..
If youre warranty is up, knox doesnt really matter, except that you cannot downgrade to older firmware. Most who want to just want to use the free sim unlock.
There will always be people who disagree, but I personally feel updating is a good idea. Better performance, more features....thats up to each person to decide though.
If you decide to update, everything you need is in General.

I agree with him
Lol, oops.. just flashed the MJB Firmware.. I read about what an unlock was for.. We had been with Centennial before AT&T bought them and are still on AT&T today, so probably over 14 years and never really thought about changing.. Guess it would have been useful if I was going to sell my phone, but I can't seem to let things go sometimes Still have my iPhone 3GS, which I probably could sold when I was done with it, but I thought I would need it again sometime (I didn't)
Anyway, DocHoliday, I came back here because I started to go through this thread you linked to in the link you posted above (enewman17's thread for updating to 4.4.2 (high success rate) http://forum.xda-developers.com/show....php?t=2789917
I decided to not flash TWRP and just flash the MJB in his Step 3 in the CWM Recovery I already had.. Then I stopped and read a few more pages of that thread, then I saw you posted this "Do not flash an ota over a custom modified rom. The chances of it going way wrong are too great. OTA's patch existing files on the device, and if those files have been modified there's a very good chance either the patch just wont take, or it'll really screw things up."
In my OP I stated I was already running a custom rom, so had a finished that guide, I probably would have messed something up somewhere right?
So I guess, where do I go from here? I am on the MJB firmware bootloader modem (that I flashed from enewmans guide) right now running Spirit Rom Android 4.4.4. I don't care about going back to stock, I want to maintain root and continue using non-touchwiz ROMS.. Though I did consider using a TW Rom a few months ago..
Ok, no problem there! Use enewman17's other thread here:
http://forum.xda-developers.com/showthread.php?t=2808654
It will update your base firmware (bootloader/modem/etc) without touching your current rom.
