Hi there,
I haven't been updated on rooting and all that jazz in a while, so please excuse my ignorance.
I have a Galaxy S3 (SGH-T999) on 4.1.2. It's stock rooted, but I don't have a custom Recovery or anything on it. I didn't (and don't) want to trip the root counter.
Is there a way to upgrade my phone to 4.3, have root working, and not trip the root counter? (Basically, what I currently have, except on 4.3)
Also, I Googled this new Knox feature I've seen people talk about, it seems like a lot of people here don't like it-- should I not want it on my phone too?
Happy holidays,

The counter is easy enough to reset if still on 4.1.2, so your best bet is to install a custom recovery through odin, then flash docholiday's 4.3 stock deknoxed rom and the new modem, and the at&t kernel for working wifi. This way you can use triangle away to reset the flash counter. If you install 4.3 with 4.3 firmware, you will not be able to root without tripping the knox counter.
Hope this helps

From what I understood back in the day when I got root, if you installed a custom recovery, you either triggered the counter or lost all your data/wiped the phone. Is that still the case?
Edit: Or was it un-tripping the counter that caused the data to wipe?
If you want 4.3 touchwiz, root, and a warranty, all at the same time, don't take the official update.
Instead, flash the 4.3 ROM zip, 4.3 modem, and a compatible kernel, using twrp or cwm recovery.
If you ever need to odin, do not use any version newer than MD5 or you are stuck with Knox and can never go back.

It still triggers the counter, but it can be reset. It did not wipe my data, but backup just in case. Resetting the counter did not wipe data either. But do not update to the official 4.3 if you want to root and still have a warranty.

Uh oh. I searched around for guides on updating like you guys said, and followed the guide here which promised root, 4.3, and no root counter... and now I can't use root, even though I installed a pre-rooted ROM.
I'm on 4.3 now, but don't have the ability to use root. I don't seem to have the Knox thing though.
I don't understand why I don't have root on a rooted ROM... what should I do?
Edit: This is the exact version I used: root66_TMO_T999UVUEMJC.tar.md5

To fix root, enable developer options by pressing build number 7 times, then enable root access for apps and adb under dev options.
MJC is TW 4.3 which includes knox. AFAIK the root66 version has knox removed from the rom, but it is impossible to remove it from the bootloader.

I checked in developer options after pressing the build number 7 times, but I don't see anything about enabling root in there...
Do I have to re-root somehow? If so, will that throw off the counter?

That's why posts need read completely. It clearly says it will trip the Knox counter in 4.3 in the second paragraph of the first post under "4.3 notes" sorry that happened though.:banghead: Maybe someday someone will come up with a knox bypass in the bootloader.

I don't understand-- it seems like it says Knox is removed in order for root to stick:
4.3 Image Notes: With 4.3 images, KNOX is removed in order for root to stick. This will flag the Knox counter. Once you flash one of these 4.3 images you now have the latest factory stock bootloader, radio, etc. Flashing a prior bootloader can hard/soft brick your device. Please read and understand what you are doing.

I took it to mean root will flag the Knox counter so it has been removed from the images.
The wording is very ambiguous...
I'm pretty close to just nuking my install and starting over with CyanogenMod, not caring if I trip the counter or not. Is it possible to do so with the current setup, or will I end up with a brick/semibrick somehow? I figure I might as well, since rooting will likely trip the counter anyway.
Yes lol

"It has been removed", it being Knox haha. That's how I understood it...
So yes, it's possible to get CyanogenMod working without a brick or semi-brick coming from this version I installed?
Yes, I could have been worded better. You can flash other
ROMs but make sure they don't include an older bootloader or your device will brick from what I understand.

I ended up just saying "eff it" and hopped onto CyanogenMod. Probably tripped the root counter, but by now I just don't care anymore.
Thanks for helping me in this thread though, I appreciate it.
Take care and happy holidays.
You did trip the Knox counter.
Just so anyone else reading this thread knows, if you value your warranty DO NOT UPDATE TO 4.3 VIA ODIN . Instead, flash the 4.3 rom , kernel, and modem zips in CWM or TWRP recovery.
Do not Odin MJC (or MK4 for you T999L people) if you want root and warranty, as once you are on the Knox boot loader you can't go back.

One of the things that bugs me about forums, finding information is a pain the butt. I just want to get my device back to stock so I can get OTA updates, GPS doesn't suck, and can use Wifi. I don't care about root anymore or using custom roms. I'm learning Objective C right now to branch into iOS development. I'm sick of the Android ecosystem, to be frank.
I'm on Wicked Rom with Android v4.1.1
Baseband T999UVDMD5, Kernal 3.0.65-DeviantKernel_07
I'm downloading T999UVUEMJC_T999TMBEMJC_TMB.zip right now, along with root66_TMO_T999UVUEMJC_2.7z
Which one do I need to flash? if root66 gives me root, then cool I'll take it, but as I said, I don't care. I'll be using Mobile Odin since I'm on a mac and I sold my PC. If I need to install Windows via bootcamp then so be it, but I really don't want to.
If I need to update the rom, kernel, modem, etc all separately where do I find those files? *scratches head*
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.

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.

Hello @serein1,
Are you 100% sure you completed the saferoot instructions completely? Also, a good way to test if you do have root is to download Root Checker Also from mine and my friends experience with samsung repairs, they don't care about having a rooted status or a custom status if it has to do with hardware. But, Not everyone is the same at samsung ... Also check if Knox is voided because safe root does not trigger Knox to be disabled. Lastly, if you don't want to risk not getting it repaired I would flash Stock rom using Odin.
Downgrade to stock 4.1.2 rom, then root it, use triangle away to reset the counter and then do the compete unroot.
Done.

Thanks everyone
I have tried the instructions as mentioned for the safe root
it gives error unsupported device and then goes away
there's another thing I have noticed the safe root command prompt window on the top says S4 and not note 2 however I have downloaded the safe root from the note 2 forum section
The knox counter is already set to 1 now DAMN
I also would like to go back to the 4.1.2 and while downgrading using the ODIN it says unsupported on the phone screen and doesn't flashes the phone
How do we downgrade from the 4.3 that has the knox to the 4.1.2
thanks again

Try to find some firmware on sammobile site or here on xda (just search for the word stock).
After that You put the phone into a download mode, connect it to a PC and choose the downloaded (extracted) firmware under the pda/ap button.
Thanks that worked and it is back to stock now.
Now just get the flash counter back to 0 again.

Honestly I couldn't tell you. I just did the update to my phone. I'm looking all that up now. As far as your back up. It's always a good thing to back up your current rom in case you ever wanna go back to it. What I did was just flash stock Rom with out root using Odin. And I received the update today. It just now finished. It takes a good min to download. It's 495mb rather big big file.

Sent from my SM-N900T using xda app-developers app
I'm of the frame of mind that you should never accept OTA updates unless you have no plans at aftermarket firmware modification. Since you are already rooted I would caution against it...even if only to establish good habits. This OTA might be safe but who knows if the next one locks up the bootloader? I'd Jump immediately to another device. I have no desire to get stuck on stock, especially with a risk of no exploit available for root...for a while? Forever? Who knows...that's a roll of the dice I'm not willing to take. The developers do amazing work and I am thankful for every moment of time they spend making roms, finding root, writing recoveries, etc etc etc. But I am not so arrogant as to expect every patched up whole to be cracked open again, by someone else no less.
It'll probably be less than a day (I've seen it take less than an hour on some devices) until a dev has a flashable zip and a pre-rooted Odin image that doesn't trip Knox.
...I've seen tons of impatient users posting after rushing to grab the update asking how to rootagain, or how to unlock the new bootloader, how to get back things they used to have...over many many many devices. Just because T-Mobile has been cool in the past is no indicator that they will continue to be cool in the future.

Which version of cf auto root did you use? I read only the n9005 works. The one for our phone (n900t) doesn't. I want to use it, but not sure which one, so instead of trial and error, maybe you can guide me where you got yours. Thanks.

you're right the one for the tmobile variant does not work, i tried it first and it put me in a bootloop.
here's the firmware you need http://www.sammobile.com/firmwares/3/?download=26282
flash through odin, wipe the phone through the stock recovery then cf auto root also through the included odin.
EDIT: i for got to mention, if you use cf root YOU WILL TRIP KNOX. if you don't want to trip knox, don't update or update but don't cf auto root and wait till someone comes out with a workaround.
About a month ago I rooted my Galaxy S3 and tried to install CM11. Long story short it did not all work out well because Knox security would not let me install any root apps. And the rumor is that the Galaxy S3 is about to receive the new KitKat update and I would like to unroot the phone before the update arrives so that I can have a chance to install it. I have tried on my own by following some instructions from some websites but so far nothing seems to work. I downloaded the correct firmware from SamMobile and downloaded Odin. When I plug the phone in and start the Odin process everything seems to be going well until a big red "FAIL!" pops up. I'm hoping I don't damage my phone in the process, but so far it hasnt been bricked yet. Please, any help is appreciated.
what model of S3 do you have? There is many.

About a month ago I rooted my Galaxy S3 and tried to install CM11. Long story short it did not all work out well because Knox security would not let me install any root apps. And the rumor is that the Galaxy S3 is about to receive the new KitKat update and I would like to unroot the phone before the update arrives so that I can have a chance to install it. I have tried on my own by following some instructions from some websites but so far nothing seems to work. I downloaded the correct firmware from SamMobile and downloaded Odin. When I plug the phone in and start the Odin process everything seems to be going well until a big red "FAIL!" pops up. I'm hoping I don't damage my phone in the process, but so far it hasnt been bricked yet. Please, any help is appreciated.

I guess u can update your device when the update comes u don't need to unroot.... The update will automatically unroot your phone....
If I am mistaken pls correct me thanks.....

The best bet is to get that firmware to flash. You can try using an unroot option if all else fails (in the supersu app, just choose Full Unroot).
But if you want to try to get the firmware flashed, we need more info about what's happening. In particular, what model device, your current firmware version, the version you are trying to flash, where you got it from, and most importantly, what does Odin say when it fails? (Copy the text in your post)

Okay, I'll get the text off Odin as soon as my phone charges to 80% or so. Should be about an hour or so.

Okay so now for some reason Odin won't add the phone when its plugged in and in download mode. Maybe its because my battery charge wasn't at 80% or higher? Or could it be because I deleted the SuperSU file? And was it a bad idea to delet the file? Kinda frustrated cause I have no idea what's going on and why it won't unroot, I just want my phone back to normal...

Did you open Odin after you plugged it in?

Of course I did. I'm going to try again later today. Hopefully it works.

Ive used odin with less than 20% battery...
Try installing supersu from the play store, then choose full unroot from the app.

I would but Samsung Knox security won't grant it permission. And I can't delete the stupid app.

Is your computer detecting your phone when you plug it in while in download mode? unplug it and plug it back in a few times to see if your computer detects/installs correctly giving a couple minutes before unplugging each time.
Once odin does detect your phone, be sure you have the correct firmware for your phone. If you have the T999, be sure to download the firmware for the T999, if you have the T999L download the firmware for that one... Check DocHoliday77's Firmware/OTA's post in the Android Development section for directions on flashing back to stock.
If you are adamant about the whole Knox thing, you can just flash the attached zip using a custom recovery to remove knox

It was just recently that Odin refused to work. Before that it was working fine but if you read my first post there were still obstacles. It all seems to be going well until Odin just gives a big read "FAIL!" at the top. And around last year when I unrooted the same phone, I always got "md5 error" but that isn't the case right now. And I do have the right firmware downloaded from SamWire.com. Hoping you can help.

If I missed it I apologize, but you still haven't answered several of the questions we've asked you. I'm only assuming you have the T999 model since it sounds like you're stock and its in your dad app Sig.... but what firmware are you on now? What build are you trying to flash? Can you copy the text output from odin after it fails? You say you think knox is blocking odin from running.....if this is the case its actually not knox (common mistake), but its not letting you downgrade due to the revision check, which is why I want to know your current firmware and the build you're trying to flash.
Without this information, the only things I can think to tell you are to try several usb cables (they do go bad, and many are only for charging), try each cable in every usb port on the computer (weird but its worked many times), or try this....
Check my Towelroot root thread in general section. Reroot the device with this method and after installing SuperSU, let it update the binary and disable Knox. Now try flashing in odin. If it doesn't work, try the full unroot option I mentioned earlier.

Sometimes if Kies is running then also it fails so make sure Kies is not running in services or you can uninstall it

Sort for neglecting to answer your questions. Just been stressed about this. But to answer some of your questions; Yes this is the Samsung SGH-T999 model running 4.3. And yes I am trying, and failing, to Unroot my phone by flashing a stock firmware from which I downloaded from SamWire.com. I'm trying to flash 4.1.1 or 4.0.1 (can't remember). And from there on I can upgrade to the newest, 4.3 jellybean or 4.4 KitKat if it is available. As for the Knox situation, I didn't say that it was blocking Odin. I just said that Knox was preventing any root apps to function. Every time I try to access the SuperSu app Knox prevents like "This app has tried to gain access to your phone. We have prevented it.". And so I was wondering if that was why I was having problems? Is this info good now? If you need more I can try and answer.

That is your problem, you cannot downgrade firmware once you have upgraded to 4.3. That still doesn't explain the Odin problem. That is most likely a cable issue as DocHoliday77 stated or a driver issue on your PC. check your device manager when you plug it in to see if your computer even detects it. If it gives the yellow triangle in your device manager on your PC, try uninstalling, then unplug your phone and plug it back in.

Thanks! This definitely helps! If you have previously updated to 4.3 firmware you cannot downgrade anymore. (Flashing older roms is ok, but not the full firmware). If you find a way to force the flash, it'll brick your phone.
So if your current firmware is MJC, you can only flash MJC or NC2 builds. If your current is NC2, then you can only flash NC2.
If you want to check for sure, install terminal emulator and enter this:
getprop to.bootloader
This will tell you your current firmware build.
If this still doesn't flash, let us know. But you could still try my other suggestions for rerooting and trying the full unroot again.
Sorry I misunderstood what you said about knox. Many people call the warranty bit part of a knox bootloader. This isn't entirely inaccurate, but can lead to some confusion, so I wasn't sure if that's what you were talking about.

Okay. I'll download the 4.3 firmware. This is weird cause last time I unrooted, I did so while flashing a ln older version. Or maybe I was mistaken. I'll see what I can do with the new firmware and tell you guys how it turns out. Wish me luck!
