[FAQ] KNOX and you

[SIZE=+1]There seems to be a lot of confusion and misunderstanding circling the forums with regards to Knox and the 4.3 OTA.
This is an attempt to clear things up[/SIZE]
UPDATE: It seems that people can find this thread, but are unable to actually READ the information presented. The most important note here is that if you are on 4.3 firmware, you can flash ANY rom you like. No, you are not tied down or locked into stock only or 4.3 roms only. AOSP roms will work fine as well. Now scroll down and READ EVERYTHING IN THIS FIRST POST.
What is Knox? Knox is both a firmware and a software component. The OS has Knox apps, and the MK3 bootloader has a Knox component too. Having Knox apps does not necessarily mean you have the Knox bootloader, or vice-versa.
How does Knox work? Because Knox is both in the OS (apps) and in the firmware (bootloader) it works in two ways. The OS components prevent attempts to obtain root access and make rooting with these Knox apps a pain in the butt. Fortunately they can be removed. In the firmware component (bootloader), Knox works to prevent the flashing of custom kernels and recoveries. If you flash a custom rom or custom recovery WHILE on the Knox bootloader, your Knox flag will be tripped and your Warranty Bit will go from 0x0 to 0x1. The Knox bootloader cannot be downgraded to, say, the MD4 bootloader because of special protections built into it. If you attempt to downgrade it, your phone will instantly brick.
Can I get root on the Knox-enabled update? Yes. For those of us who DID NOT take the official OTA and DO NOT have the Knox bootloader, we can get root on 4.3 by injecting it and removing the Knox apps. For those WITH the Knox bootloader, you will need to wait until a full stock MK3 tar is available, which we can then use to make an Odin-flashable MK3 stock rom with root injected using the de-la-vega root method.
Can I downgrade while on 4.3? You can flash roms no matter what Android version they are. That is perfectly fine. But you cannot downgrade the bootloader if you have the Knox bootloader, or else it will cause your bootloader to become corrupted and give you a fancy paperweight. Again, for those who DO NOT have the Knox bootloader, you needn't worry about this/downgrading firmware since the Knox bootloader is what prevents you from doing this. Downgrading your bootloader includes: attempting to flash full stock tar of software versions < MK3, etc.
How can I tell if I've got the Knox bootloader?
Boot into download mode (through custom reboot menu, or by powering off then holding Power+Home+VolumeDown and then VolUp when prompted). If you see a line that starts with the following, then you've got the Knox bootloader. I will insert a picture showing how it actually looks soon

No way to remove bootloader Knox ATM.

I've seen several posts mention "tripping KNOX" or "voiding KNOX." What does that mean, exactly, regarding rooting a phone? Does it just mean it voids the warranty if you need to get support from Samsung/Sprint? Or are there other adverse effects?

Mostly just a visible warranty void.

Samsung bought crapple disease. So sad, but its my excuse to buy a nexus.

As said above, a voided Knox is mostly just a highly visible warranty void. Your local Sprint store may or may not care, or the specific Samsung rep that you deal with may not care, but it's easier just to not have to deal with it to begin with.

Does this mean there is already a touchwiz 4.3 ROM we can flash or do we still have to wait?
Sent from my SPH-L710 using Tapatalk

The biggest thing here is the fact that there is no full tar file to restore. So even if you do not care about knox or warranty. If something goes wrong with a flash or anything else you can't use an older tar file let's say MD4 or LJ7 or anything because you will end up with a brick. There is nothing to use to ODIN restore your device. Once you go 4.3 with Knox you have to stay 4.3 and even if you wanted to stay 4.3 and wanted to restore that there is no tar file at this time.
Have a great day!

I have a question I think we talked a bit about the problems the knox bootloader brings into the system. My question is the opposite what does it fix / change?
Im thinking along the lines of somebody modding the update so an old bootloader would be with the new rom would that be an issue? I think i remember hearing something about wifi being the problem but any clarification would be nice.

Right now, wifi is broken with the old bootloader and 4.3 rom...happened on the other devices too (tmo s3 and sprint s4)
But there is a fix: flash at&t kernel. But it messes up screen rotation. So i'm trying to come up with another fix that will let wifi turn on properly and let screen rotation work properly too

You = rock. Or some other awesome thing.

So is this Knox a Sprint thing, or a Samsung thing?
I can understand the reasoning for Knox(money) but, dang, I guess it's a dog eat dog world out there.
This doesn't affect CyanogenMod does it? I'm scared...
edit... I remember reading about a brick api or command, I never executed it, sounds nasty, is this what they use to brick peoples phones if they try to "hack" it?

This would be a we-can't-update-the-bootloader thing lol. And we can't do that because it has Knox, which is Samsung's doing
This shouldn't affect any AOSP roms because it uses a different kernel and builds its own WiFi libs

From what I've read Knox is Samsung's attempt to provide strong security to their phones for the enterprise customers. As you can imagine, allowing system level access to files can be used to get around a lot of security measures that IT people would like to enforce in their client's devices. It makes sense at the enterprise level, but it's a pain for anyone who want's to mod their phone.
So I think the answer to your question is, unless you are using your phone in a locked down corporate environment then there really is no advantage to Knox. Too bad it can't be turned off, at least not officially.

KNOX warranty void

What does this truely mean. I just rooted via ODIN and my flag was tripped 0x1, does the flag geg tripped regardless if you root or install custom roms ?
Sent from my SM-N900T using xda premium

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.

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.

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.

Knoxreset.com legit ?

Hi,
after a long time using iPhone i switched to Android (Note 10+ Exy.
I considered to root it but dont want to loose all Samsung Apps etc. I found a Website called knoxreset.com which tells you that it can put the knox back to 0x0 and "restore" all Samsung Apps.
I tried to find some reviews about this Website but found nothing. I know that Knox now a days has something to do with the Hardware and as im a newbie, i wanted to ask you guys if this is legit or a scam ?
They sell it rn for 45 Dollars.
Thanks for any help!

I would go with a scam... Tripping knox literally blows an efuse. Once it blown that's it... It is blown for good on that motherboard.
The site is misleading in what it does. The app involves rooting (or uses existing root on) the phone, installs (possibly uses if exists) a custom recovery and merely makes the trip counter looks like it wasn't tripped (it does not actually change the knox trip counter). It's a purely superficial mask and nothing more.. also if I recall correctly this is something you can do yourself.
Also the site says it doesn't effect knox, so any apps which depend on knox itself won't work.

It's easy to fake reset Knox if you are rooted which is exactly what they are doing. It will fool some apps that won't work if knox has been tripped but it won't fool Samsung and as soon as you flash back stock then it will show Knox tripped. If you want root but won't to fake knox then there are guides out there

No, banking apps, samsung pay, and other apps will not work, only some apps can be fooled by hiding root, just consider this before rooting, as for tripping knox, there are some cosmetic implementations that make knox look 0x0, but just for show, this can not in anyway be reversed, apps specifically looking for the e-fuse status, will never be fooled

The ONLY sure fire way known to reset KNOX is Motherboard replacement...
This will be expensive and will also change your IMEI and Serial number...

yeah it definitely looks like a scam website @scottusa2008 is definitely on the mark. once that efuse is blown, its blown.

Okay guys thank you very much for the help, ill do some more research and will probably go with the Dr. Ketan Rom

Ex developer of KNOX Reset (Disabler) application
Hi,
The application listed at KNOXReset.com cannot indeed reset the actual KNOX counter. It is also mentioned on the store page before purchasing the application now.
It has been designed to spoof the string in Odin mode and display 0x0(0) regardless of actual value. It works only on certain devices.
Also, it now includes modified S applications which work even on rooted devices.

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.
