Seriously, there are tons of threads on this. You didn't do any research before rooting your phone?
Once tripped it can't be reset. If you planned on flashing roms, there it's no way around reporting the Knox flag. Now that you have already tripped it, you can't go back.
Whether or not it will effect you depends on how you use your phone, software out hardware issues you may have and if you try to get warrantee repair. For many it it's not a big deal.

I did do my research Im just asking a question maybe there was an update on how to change the void but obviously kot . Thanks anyway. Dont get all hyped thats what xda is for

Hi, I got my note 3 recently and all i have done is just root my note 3 so far. but i have been doing some readings. from what i had found is Knox is a software on your phone, i am guessing and this is just a guess if you use the bloatware remover it might delete the knox program and files from your phone. It might trigger a reset on the counter. I remember reading the list of files it deletes, and it delete all of knox files and folder and a bunch of other stuff but you can edit the script to make it only delete the knox. It might delete the counter or reset it. And you can just reinstall it back and see if the counter is back at 0. remember i am just taking a guess here, does any 1 think this might work?

You cannot reset the Knox flag once it had been tripped.

You didn't delete Knox fully or it would not have the counter. Trust me chain fire tried with no success. He has been one of the pioneers in getting things done and could not.

I was referring to what I quoted you saying about blowing an e-fuse by removing Knox. I'm not talking about the check component in the bootloader or wherever it's stored - just the software components that are very easily removable, and do not seem to have caused any adverse effects (aside from the arguably undesired Knox 0x1 flag).

It's a component Samsung decided to build into their new phones and Android builds that is allegedly supposed to be helpful for device security, especially when used with a corporate mobile device system.
Currently, if you flash a phone that has Knox installed with non-factory ROM, Recovery software, etc an at-bootup counter is "permanently" tripped indicating that the device has been tampered with.
I put that word in quotes because we all know with enough time and resources someone will surely figure out a way to reset that counter, if not remove it altogether.
SHORT VERSION: it's a piece of garbage that Samsung and Tmo can use to not uphold your warranty (since it technically voids the entire warranty if you flash custom stuff).

Guess I'll stay away from Samsung devices then. If I could get a Note 3 that has the camera features and S-Pen, I'd be happy.

Interesting, i got a few question i want to ask. I root my t mobile note 3 recently using the new method that don't trip the knox counter. And i install several apps that require root access. I know if you install custom rom it will trigger the knox, but i won't on my and its still stock at 4.3. My Question is what about apps that require root access? I got ES file explorer, es task manager, game guardian, cachemate for root users free, cpu tuner, and titanium backup, does those trigger the knox? And is efuse short for eletronic fuse? if it is, can't you just replace it to undo the knox?

Apps don't trigger the Knox flag, flashing a kernel roms etc do. Efuse is in the snapdragon processor.

It voids Samsung warranty not TMOBILE. So ur good for 1 year
TWEAKED 1.0 NOTE 3

Yes, Knox is Samsung thing, T-mo has nothing to do with it and some people already suggested, T-mo doesn't even check Knox flag for replacements etc, at least so far. I asked here before if it's e-fuse and got different answers, so I ask again : are we sure it's e-fuse or we just speculating? The reason is, there was a guy in international forum claiming Samsung reset his Knox flag, which would be not possible with e-fuse. BTW I just updated my old GS3 to 4.3 and it added Knox to it, so I got mad and rooted it to just to delete this stupid Knox, so now how do I check that flag on it? It says custom because is rooted, but where is the Knox flag?

You see the Knox setting when you put your phone in download mode.
As for resetting the Knox flag, I've not seen a confined resetting of it or better said, if it can be done, no one outside of Samsung has been able to do it and prove they have.

So I've been searching around and have not found out the answer to these questions... I'm assuming the answer is "Yes" to the first but want to confirm:
If the KNOX flag is tripped, the KNOX software will no longer work. Ever (assuming we never get a 0x0 reset). Correct?
Now for the next question, assuming "No":
If I use the RDLV to root without tripping KNOX, will the KNOX software still work?
I ask because my company does have MDM and supports KNOX and I may want to use it in the future.

What is the easiest way to root this device?

I don't wont to trip any counters...

kingo would be the easiest way. install the program on your computer, connect your device, click a couple times, let it do its thing and you'll have instant root. nothing else changes and nothing is lost. there was some bad feedback about the app but its been cleared up since then.
many people have used it.

Seconded. It probably won't even trigger your Knox flag (I have rooted several times with Kingo and my Knox flag is still 0x0)

Why would we not want to trigger that, does that make Knox useless? Reason I ask is because I do use this phone for work with an exchange account and have been curious about this. If I use Knox to just try it out will that screw anything up?

Tripping KNOX may make the phone incompatible with certain enterprise scenarios. Using kingo wont trip the counter so it shouldnt matter in your case.

Check out this thread which is linked in the FAQ sticky here.

There is one person claiming Kingo tripped his Knox flag despite MI7, so unless we figure exactly why, I would be careful and maybe wait a little.

I don't know about that other person, but I had the same issue, I'm still on MI7, I used Kingo to rood my Note 3, everything was fine until it asked me to install an app called MtkCamera, which I declined, then Kingo kind of frozed and then it restarted. When I checked the Knox counter it was tripped ...so, I would suggest caution with this.

Well, first of all I would ask why do you want to root to begin with and secondly is that reason more important than using it for work. At least In theory Knox was developed for people like you, who have one phone for work and personal use, by providing secure environment for sensitive data. Even if your job doesn't use Knox yet, they may in the future. If I was doing banking or CC transactions on my phone I would seriously consider Knox as well, albeit I have no idea if it would actually serve it's purpose well. If you just test Knox you would need to download some extra software from Samsung, Samsung is aware of security holes and already patched them in the latest bootloaders, so Knox flag will trip when rooting for sure, so I wouldn't be surprised if those security updates wouldn't be the first downloaded as part of Knox suite, when installing it. So here I would speculate, since I have not tried it myself, that you should either root and take your chances, or use Knox and forget about rooting. I wonder if PTJunkie didn't play with Knox, or somehow manage to get Samsung security update, to get his flag tripped, where others didn't. I actually disabled updates to make sure I don't get any new enhancements from T-mo or Samsung.

If you have used Odin before,
root de la vega is easy.

I root because i have a lot of apps that required root like titanium explorer and root explorer .
Moreso, I need to freeze all the bloatware like google now and s voice.

I have 2 quick questions:
1. root delavega uses att rom, att phones don't have wifi calling, is wifi calling still working as usual on rooted, t-mo phones? or in general Is there anything T-mo specific that breaks after root?
2. I assume bringing the phone back to original would require reflashing original T-mo ROMS? Anything else needs to be flashed?

I haven't flashed back to tmobile stock yet. I still have wifi calling and I make sure to disable my tmobile account because they can tell if you are rooted.

Yeah, when you run that system check, but what can they do? Even if they cared, I'm not sure if they do, if your phone is stock with no flags tripped, I would argue and play stupid if needed return, or repair. Also I wonder if this check could be somehow disabled all by itself, for example by taking away some permissions.

Reset knox counter in wifi only version (8.4)

Hi. I have the wifi only version of the tab S 8.4 (T-700) and it has the Exynos 5 Octa 5420 chipset. I read that it is possible on other devices with the same chipset to reset the knox counter back to 0x0.
What do you think? Anyone has any experience with this?
LE: after reading the original thread carefully i noticed that it's not a simple software solution. Maybe can be done in a repair shop

we, as end-users, don't have the tools to do so. The flag is resetable we just don't know how to do it yet.

Was talking to a sales type at BB about rooting/ROMs, etc and he related that often he's gotten tabs with Knox tripped. Says at the retail level he has the ability to reset Knox with software. Didn't press him but must say if true it would be the first I've heard of it.

I worked for Samsung at the store booth and we had no way to reset the counter or even flash stock firmware on a rooted device with much more tools and samsung specific software so i find that hard to believe lol. I am certain he was mistaken.

That was pretty much what I thought also....

If it was user possible, Chainfire probably would have found a way to "reset" the efuse by now.
Maybe those with JTAG equipment might have a way, but not heard of it yet.
But unlikely a simple app will do it these days, all known exploits have been patched by Samsung.
Plenty of info on XDA discussions etc. I just take the risk and root, and if warranty is not honoured, bad luck, I know the risk before hand.

I lost my warranty void because of this knox **** counter huhuhu :crying::crying::crying:

Even though Knox trip flag = 0x1 if I restore a non-rooted stock rom...

... will Knox features work again? Such as secure folders?
I honestly don't care much about these features. I much prefer having access to Ad-Away. But if I do use Odin to flash a stock ROM (Without re-rooting) on the phone, even though my Knox flag is still tripped will Knox features work again?
Thanks

Once Knox is tripped it will always be tripped, you can no longer access the Knox features and I also believe that the Android/Samsung Pay system will no longer work

You can go back to full stock but rooting will trip Knox and this cannot be undone which will prevent Knox related features from working (i.e Samsung Pay etc..).
You also run the risk of not getting Warranty support if Knox is tripped.
Hope that helps.

well, it is for security reasons, only a really small number of people root their phones, small compared to the total number of devices out there.....

Right.. I am seeing that... I do a lot of penetration testing etc, and some of the software I want to use requires root. I have this stuff on my laptop and other devices, but would like to have the option to utilize it on my phone as well.
Just stinks you can't reset it back..

Tripped Knox with unrooted device

The other day I thought it would be a good idea to root my phone (S20 Ultra Exynos), as it's been many years since I've done it (S6 was my last rooted device).
Anyway, I kept running into issues with connecting to my watch, and getting payment apps working (on account of the root), and decided it was not worth the hassle.
So I unrooted the device via flashing stock firmware in ODIN and locked the bootloader.
I noticed my Samsung Health app didn't work, which was strange. Upon research, I found it was due to Knox being tripped - which was confirmed via downloading a checking app from the play store.
I know that there are patched S Health apps that would allow me to bypass knox, but is there is any way to reset the knox counter so that warranty is no longer void?
Are there also any other implications from this.
So far all my apps work fine, except for health.
Cheers!

It's a micro efuse inside the chipset that blows when you trip Knox.
The only way to fully undo it be to replace the mobo. Yeah... like Fort Knox.

Thought that might be the case.
Bloody Samsung, that's so ridiculous!
Oh well, I haven't seen any other issues with it tripping so far. Warranty is already void anyway since it's water damaged and have had the screen replaced by others.
Thanks!

You're welcome.

It's a shame that it can't be undone... I mean, what harm does it do if the phone was rooted (or even attempted to be rooted... it didn't even work!) once.

It's so you know the phone's security has been compromised. Rooting and custom roms makes troubleshooting much more difficult.
Can't blame them for not wanting to troubleshoot other people's firmware on top of their hardware.
