So I have a problem guys, I'm going to tell you all the long story, I just recently bought a S4 from Telcel in México, LTE edition, the model is SGH-I337M, and came with build I337MUMUAMG1, 4.2.2.
I was anxious to tinker with it, so first thing I did as soon as I came home was rooting it with CF-Auto-Root, everything until that point was smooth sailing, but I couldn't make the I337M version of Philz Touch Recovery to flash via Odin, so I flashed the GT-i9505 version and IT WORKED, it booted to recovery normally, rebooted to system, etc. So I thought "oh boy, I'm ready to go". But before that, I read that for data & Wi-Fi to work properly in 4.3 Custom Roms I had to flash the 4.3 modem.bin file via Odin, so I did that. No OTA, no 4.3 Stock Rom, only the modem-bin file. The modem version never changed in the "About Device" tab to "I337MVLUEMK6" like it was supposed to do, it stayed as "I337MUMAMB2" but I also read that was normal so I didn't think about it much.
After that I went into recovery with my ready-to-flash files in my SD, wipe my system/data/cache/etc without making a Backup because that's how retarded I am and try to flash my ROM only to get it aborted every time due to "assert failed: getprop("ro.product.device") == "jfltecan" ||" issues, so I assumed it had to do with me using the GT-i9505 version of Philz Touch with a I337M Canadian Custom ROM. I shat bricks for a while because I had wiped my system and I had no backup, so I just turned my phone off, downloaded the "I337MUMUAMG1" Telcel Stock Rom, turned on my phone in Download Mode and flashed it via Odin while I prayed.
It worked, it booted, everything was alright with the world again (but not so much on my pants where tons of bricks were shat), I had voided my warranty but whatever, I was gonna Root and Triangle Away that thing to make my phone fully stock again, so I get ready to do exactly that, get my phone into Download Mode, and Root it with CF-Auto-Root, again, it worked, it booted, and had the SuperSU icon, smooth sailing again, OR SO I THOUGHT.
I open SuperSU to update dem binaries and a pop-up emerges saying that Samsung Knox had been detected and if I want to attempt to disable it. Oh boy, I was not ready for this, I hadn't recovered from the last shatbricking session, and now my pants were a national disaster area. Anyway, I also read that using Triangle Away with a Knox enabled phone was a highway to a very expensive paperweight, so thankfully I was smart enough to don't try it.
As I kept shatting bricks I decide to reflash the Stock "I337MUMUAMG1" Telcel Rom via Odin to keep my phone as safe and near stock as possible, everything worked, and now I'm running the "I337MUMUAMG1" build, with no root, stock, with yellow triangle and apparently, Knox. :crying:
I got curious about it, so I went into Download Mode to search for the Knox Warranty Void Flag... But I didn't got it, neither the Warranty Bit. On Download Mode I get only the Usual:
ODIN MODE
PRODUCT NAME: SGH-I337M
CURRENT BINARY: SAMSUNG OFFICIAL
SYSTEM STATUS: OFFICIAL
USB-CONFIG-LSB: 0x30
WRITE PROTECTION: Enable
And I don't have any Knox apps on my drawer, but they appear on the "Application Manager -> All" menu, so I'm confused as hell, and since I can't check my Bootloader version I can't know if I have Knox on my bootloader or only on my Rom. And I'm way to scared to try anything, and also scared about OTAs and updates since I don't know the state of my phone. Any help on this?
tl;dr: Got brand new SGH-I337M with I337MUMUAMG1 as Stock. Rooted, Flashed Philz Touch for GT-i9505, Flashed 4.3 modem.bin only, Tried to flash Custom Rom, messed up, Flashed Stock I337MUMUAMG1 again, Rooted, got Knox popup upon opening SuperSU for the first time, shat bricks, Flashed Stock I337MUMUAMG1 again to be as stock as posible. If I boot into download mode I don't get Knox Warranty Void Flag in the Download Mode, don't have Knox apps on my App Drawer but I see them on the Application Manager -> All. Too scared to try anything until I know if I have Knox enabled on my Bootloader or only Knox Apps on my Rom.
Any help with this will be greatly appreciated, many thanks in advance, and thanks for reading.
EDIT: FORGOT ABOUT SOMETHING. After Flashing Stock I337MUMUAMG1 For the second time after getting the Knox warning popup on SuperSU, I got an OTA, couldn't cancel it but I don't know if it changed anything, since my build number was it was I337MUMUAMG1 still, it was a 250mb file.
sounds like you have knox yes. As to why it doesnt show in download mode, I can only speculate that when you flashed back to 4.2.2 the recovery was replaced with a pre-knox variant. If you're seeing knox in app manager>all as you mentioned, then you have knox yep. I have the same, just a shortcut, then knox crap in app manager> all.
Interestingly, I came from gummy 1.1, with root and CWM recovery. However since i was rooted, i couldnt obtain the 4.3 update OTA. So, I downloaded the 4.3 stock, flashed with odin (auto-reboot/f reset selected) and my knox shows 0x0. Granted I don't have root, but my main reason for this was battery life, which sucked balls on 4.2.2 rogers variant. 4.3 rogers variant is MUCH improved. I'm actually getting better life out of the stock fw, then i was with gummy 1.1. I hear all these horror stories, but I have yet to have a single app crash on 4.3 stock (i do miss xposed tho)
I haven't' re-flashed and tripped KNOX because it isn't just some security crap samsung threw on to stop custom recoveries/kernel's etc. It's actually Samsungs corporate solution for BYOD policies. The whole reason it blows the fuse, isnt just to stop warranties either, it's to communicate with exchange/corporate policies and let exchange/network know that your device is secure and following corporate policies. We all know android and linux are one in the same, adding this now gives samsung the ability to sell a managment suite (like BES in blackberry world) that uses knox for remote wipes/locks/factory reset/anti-theft. granted these exist already, but in a basic state. Look for these to be expanded on shortly.
If you blow your efuse, and use active sync , your going to be up **** creek shortly. I'm going to wait until this is defeated. Yes Knox is a hardware based efuse (the flag), but make no mistake, it is software solution and thus can be exploited. Patience is key here, imho. Just wait until the knox based sys admin tool is released for admins. anyone with a tripped flag is going to have a problem (if in business world). Sorry if I ran on a bit there, but yes, it sure seems you have knox and you should treat the device as though you do.
oh and the new SSO functionality is provided by knox, so if you can't use it, no single sign on for you i'm afraid.

Certain KNOX elements are present in 4.2.2 builds, however, the entire KNOX implementation (Kernel and KNOX suite) are only on 4.3 builds. More than likely, the version of SuperSU you are using detected that those certain KNOX apks (from 4.2.2) are on your phone and reported the "Samsung KNOX has been detected..." message.

So that means there is no Knox in my boot loader so I can reset my triangle counter to be as stock as possible to keep my warranty?

I have no idea about resetting the triangle counter. I've never needed to do it, so I can't help you there.
Guys, I have a question related to this.
I have I9195L (Latin version of S4 mini) and I have read about knox software which may cause issues to rom flashers like me (I used to have S Advance and tried many roms until it died)
When I enter into flash mode, I noticed that there was no knox flag at all (like the ones I saw on some other users shots), so my question is, do
Do I have that knox crap or not?
I do realized that I have some knox software installed, like knox store (I didnt touched anything of this just in case).
Can I safely try other ROMs, including Cyanogen mod?
I have rooted using the safe method posted somewhere around here in the forums.
BTW: I have stock rom... for the moment...
Please let me know.
Thank you in advance.

Yes. However, the best way to keep knox untripped to return for warranty is to simply flash the stock fw via odin. Poof, root gone, and check the f reset flag to reset the flash counter safely. You also have same scenario I did. I was running gummy 1.1 (back in nov) when 4.3 ota was released, so I flashed 4.3 via odin and knox is still 0x0. Kingo will root 4.3 and keep knox at 0x0, it did for my i377m and a coworkers as well. You can use wanam to fake official and keep ota updates for the upcoming kitkat update. Just be prepared to flash it via odin, as nobody really knows how supersu in survival mode will react to the 4.4.2 update ota. Only stipulation is you CANNOT run a custom recovery without tripping knox, or a custom rom. So I simply use xposed + wanam and customize the TW firmware that way. I have root, I have my warranty, and I can rip out any bloat I care to. HTH.
Guys, cyanogen does trip Knox and Odin does not trip Knox?

Cyanogen trips knox yes. Odin will not, provided you arent attempting to downgrade to say, 4.2.2 from 4.3. Once on a knox "infected" bootloader, cant downgrade without knox tripping.

Thank you very much for your response.
Final question, if I don't have Knox in my loader (I don't see the flag in Odin mode) I can install cyanogen and go back to stock (4.2.2) if I want to and the guaranty should be fine, right?

Provided you dont see any knox lines while in download mode, or odin mode, yes.

**UPDATE**
So I un-rooted with SuperSU and Knox is still 0x0. How can I just re-flash my phone back to factory (where/what file do I download) with what software? I can't recall if I deleted any stock apps. I just want it 100% back to factory out-of-the-box.
Thanks in advance!
*old info for reference*
Hi there,
I'm sure I've missed it but I just want to be 100% sure so I apologize if this has (probably) been asked 100 times.
I rooted my Galaxy Note 3 Verizon with Towelroot as soon as it was released. It worked great and knox is still 0x0. I need to do a warranty replacement on my device due to a faulty charging port and need to remove my root access.
Info:
Model: SM-N900V
Hardware Version: N900V.07
Android Version 4.4.2
Knox status: 0x0
No ROMs have been added. Just added root access to stop some apps from running.
What is the proper way to remove root access without tripping Knox?
Probably better safe to just do a full on reset. I found a guide but I'm prevented from posting links... But it involves running Odin and reflashing the default firmware. would this be the correct way to reset/unroot and not trip Knox?
I would like to unroot and just do a full 100% reset as if it was just being pulled out of the box without of course tripping knox. In searching, someone said to just use Samsung Kies software: "under the firmware upgrade menu. It will fully wipe the phone and return it to stock." Is this a correct method?
Thanks!
-edit-
Also just found this on kingoapp:
"How does this KNOX Counter work?
Under what circumstances will KNOX Counter be flagged or tripped?
The KNOX Counter WILL NOT be flagged or tripped when using Samsung Kies or Odin to flash a stock ROM."
Seems like I'm answering my own question. So is Samsung Kies the best route? Does the above statement apply even if you're already rooted?
In superuser setting, there is a menu 'full unroot', use that.

Hi, thanks for the reply. I never could get superuser setup and working, main reason for root was to freeze/remove some stock apps.

In searching, someone said to just use Samsung Kies software: "under the firmware upgrade menu. It will fully wipe the phone and return it to stock." Is this a correct method?

Knox will not trip as long you doesn't flash custom recovery or kernel or custom Rom.
Warning:
Factory reset using stock recovery will wipe your internal storage.
Backup all your file in Internal storage first.
Software needed to flash stock rom,
I use Odin V3.09
Firmware = download at sammobile website.

You can easily search on the q&a section on how to reflash your phone. But if you don't know how to do that, I suggest you read a LOT before you attempt to reflash.
Your original post shows that you have absolutely NO idea about how to do anything to your phone and keep it in a working state, or what any modification implies.
If you lost knox, there is absolutely NO way to get it back. Reflashing to stock will have NO impact on the state of the knox. If the knox flag is triggered, then your knox apps have stoppped functioning and, like I said before, there is ABSOLUTELY NO WAY to reverse that.
I really don't know why the others told you to reflash to stock. I thought it was general knowledge that once you lose knox, it cannot be reversed and you also lose the knox apps.
I know i repeated myself a couple of times, but with your kind of people, repetition is the only way to make oneself understood.
Good luck dude!

To my knowledge every Root related thread mentions, very explicitly, that rooting prevents you from using the KNOX app.
Which makes perfect sense, since KNOX is a security container meant for storing secure data. Once you root, no part of the device is truly safe from tampering.
Once the KNOX flag is 0x1, The KNOX app is disabled and can not be restored. If you want to use KNOX, I'm afraid you'll have to buy a new device. The 0x1 flag can't be reset.

OK, so I'm new to this ROM-flashing stuff, and would like to install TWRP on my S4. The problem is, Samsung runs these trade-up programs every so often, so I do eventually plan on restoring the S4 to its original recovery. I was able to find an article from 2013 about the S4's stock recovery, and it also provided a download link to the recovery, but my question is, since that was released was 4.3 JB was the newest version, will that be an issue if the device is running 5.0 Lollipop instead? Basically my question is: did the Lollipop/KitKat update come with a new version of the recovery mode that is required to run these versions? Or is the recovery never updated throughout a device's lifetime?
You should consider this first:
Flashing a custom recovery will trip Knox.
The question now is: Will Samsung accept the phone if Knox is 0x1?
As you may or may not know, Knox status 0x1 is permanent. So even if you return to a stock recovery, Knox will still be 0x1.

They're unlikely to check that part. They look at the device, call the secret code to test the mic, camera, display etc, and it's marked good to go. Heck, I highly doubt they'll even notice if I was running TWRP, but just to play it safe.
I was trying to make sure my KNOX counter wasnt tripped before I ordered the services being provided by imeigurus.com I thought I could just check and return to the home screen. not the case. what do I do please help. I dont know what im doing.
I foolishly did the following:
**YOUR DEVICE CAN NOT HAVE TRIPPED KNOX*** KNOX COUNTER MUST BE 0X000
FIND THAT BY POWERING YOUR DEVICE OFF.
please take it easy on me when you reply. I now realize how STUPID it was for me to do something without knowing what I was doing in the first place.
You seem to have some issue you're not describing at all.
About knox tho all you need to do is boot the phone into bootloader mode, or download a knox checker app from play store.
Honestly unless your flashing roms and kernels or custom recovery to the phone, or if you rooted it in any way except by using the engineering version bootloader, your not going to have tripped knox. If you have tripped knox you cant untrip it. It is an actual fuse in the phone that literally blows. All the knox counter really does is check if the fuse is blown and counts the number of times unauthorised changes were made to the system.

What do you mean by you can't return to the home screen. Have you tried holding the power, home button and volume down button until the phone restarts. And what djdunn said is correct and you haven't fully explained the problem for people to fully help you.
