So... Where's this Knox thing??

Hey all,
I have an s5 on EE in the UK.
Heard about this Knox security software. It shows in my list of installed apps yet I can't seem to locate where it is?
Also debating root... Not sure if it's worth it, but did want to have a look at Knox.
Thanks

knox is a security implemented by samsung, it is active in the background, has no app for that. basically it "protects" samsung warranty better than the triangle in download mode witch shows how many imes you flashed, if you had roted ur device, in download mode will show u have 0x1 warranty voided.<---- thats basically KNOX.

you are in the UK so Knox doesn't void your warranty once tripped

I check my insurance which I took out for my phone when I got it. They state that modifying or rooting will make my insurance void. How annoying. Is there some legality involved?
Thanks!

No. ^
KNOX is a security container -> a place where you install apps inside a secure container that cannot be tampered with on a high level TrustZone security algorithm.
It's great that the person above said what it essentially does to your device, but what he explained above is what happens when the TrustZone between the software and the hardware is breached during root/downgrade/unsigned flashing. This essentially would allow the viewer of the KNOX status to know when the device does not trust it's own body with secure enterprise level apps (Application Integrity), hence the KNOX warranty bit will be set from 0x0 to 0x1 meaning "I will not ever run a secure container anymore".
You won't find KNOX 2.0 on your device as this is now a paid service for enterprises at a rate of $3.60 and it is only set up on your device when you have the KNOX 2.0 kit deployed on your device, unlike KNOX 1.0 where you get to enter KNOX mode anytime you want.

Hello,
KNOX is availble on all new Samsung Galaxy S devices. The S5 (G900h - Octa/Exynos) has KNOX. this can also be checked by opening the Application manager and scrollin right to where it says "All apps" if Knox isn't in this list then more than likely you dont have it.
Chances are you do.

In order to use KNOX you need a KNOX license and to have the device enrolled on the MDM server. Without any of this KNOX will not work. The closest you can get to KNOX (As a consumer) is to use private mode. :good:

Yes, but Private mode does not offer enterprise e-mail app nor contacs lists separetly.
KNOX on S4 works quite fine but since S5 Samsung said is no more freely avaiable - you need to buy license.

[Q] What are the effects of a tripped KNOX on a Galaxy S5

Hello community,
I have a Canadian Galaxy S5(SMG900W8 - kltecan) with Rogers, currently running Lolipop 5.0 with the LRX21T.G900W8VLU1BOC1 build. I have it since 8 months and I'm beginning to be really tired of Samsung's bloated OS, sometimes it gets sooo slow and the phone becomes so hot. I know how to keep good care of my system and did many clean restores but it still gets slow after some weeks.
I want to install Cyanogenmod or something similar to completely get rid of the stock ROM, I know doing that will trigger the KNOX flag and I know it voids the warranty but I'm at a point I dont care about it anymore, my question is. In what other way will a tripped KNOX affecr my phone? For example if I ever flash back the stock firmware, will I still be able to use the features such as "Private Mode" and the Fingerprint scanner? Because those are some features I really like and care about. And also if I ever resell it, I want every stock feature to be functional...
What do you guys know by experience?
Ive read many KNOX threads before posting this one, it answers some stuff but not my exact question.
Thanks in advance!

Tripping KNOX = void warranty in some places
Other than that, fingerprint and private mode still work fine on my S5 with KNOX 0x1 tripped
Not noticed anything not working

Are you sure? Because I tought the whole KNOX software side in the phone was related to all the advanced security features like encryption, fingerprint, private mode etc... Isn't the private mode in the KNOX container?

Am I sure? I just told you it works fine on my S5, yea pretty sure lol
Tripping KNOX just switches the KNOX notification from 0x0 to 0x1 so Samsung can see it's been modified an don't have to honour warranty
I've heard it breaks domain/business related stuff, but I don't use my S5 in a business environment so can't comment on that, but for myself, everything still works exactly like it did with 0x0

Knox apps destroyed

Hi just got my s8 plus and I'm just wondering I want to root and been searching around about what tripping knox brakes but keep getting mixed views
I will be rooting and flashing a custom Rom and kernel would someone be kind enough to list every app that get broken and is not fixed even by a custom Rom or kernel (like iris scanner,s Health, ect)
As I really want to root but don't want to damage too many apps in the process
Many thanks also my model is the SM-G955F

Well if that's it then I'll go ahead and root as I don't use them 2 apps anyways
Thanks

No unfortunately not, Knox is a fuse on the motherboard. Once tripped it burns. So far only way to get Knox back would be to change the motherboard

Yes but the apps and system dont read the statuts directly from the bootloader but from the kernel, this is why there is a kernel that has faked 0x0 knox, but the fuse is still blown yes.

You can use terminal to change Knox to 0x0 but still. S health will work and some apps, but not secure folder or Samsung pay

so, knox tripped and rooted on stock unmodified rom :
safety net fail : (no apps like samsung pay, Pokemon go, Mario run, snapchat login ,etc)
no system updates
samsung apps won't work : samsung pass, samsung pay, Shealth, secure folder, issue with private mode on samsung internet,
if you use a custom rom most of stuff CAN be fixed like
safety net pass with magisk hide (root)
s health work
private mode on internet
BUT some are permanent and can't be fixed even with custom rom so once rooted , no way back except buy new phone
samsung pass, samsung pay, secure folder
Remember that once you are rooted and knox counter is tripped (0x1), its irreversible and can't be "unrooted" or be official and reset knox counter even by flashing stock firmware though odin because since galaxy s7 the knox counter is not software related but its hardware. its an electronic fuse and if you root or install custom recovery etc the electronic fuse will broke and broken fuse mean tripped knox counter. this is because even flashing stock firmware is useless, as most of Samsung apps knox related don't only check root but also the knox counter, so unroot won't help. so think twice before rooting your device

su
resetprop -v ro.config.tima 0
Type that in terminal. It will make Knox show 0x0 on device ONLY. Download mode will still show as 0x1.

its useless, Samsung knox apps dont check if they see 0x0 but it just put some electricity though the knox fuse and if it get though it its ok but if the electricity dont success to get through the fuse it mean its broken so I mean knox is 0x1 and rooted.
fake knox counter is useless as every knox eligibility checks are hardware and not software. fake 0x0 is only for you ^^to reset the counter only way is the replace the motherboard, even Samsung can't reset it

There has to be some hardware abstraction layer, you can't just test the fuse each time, that would mean that the apps have really low level rights/api to do so wich is risky. The bootloader tests the fuse and writes the value to the kernel, wich can be faked to make some apps work.
If the value is checked by apps then there is a software value other than the hardware status.
But dont quote me on that.
For apps that dont work i think there is some selinux policies issues or root gets detected.
Why would devs include the fake 0x0 counter if it was useless ?

darn making me think twice about rooting now i mainly want it for debloating,apps ad blocking,viper4android,and a few mods like stereo speaker and camera mod
also the youtube mod which allows us to stream 4k (i know we only have 2k display) but i still like to stream in 4k

I have rooted for the exact reasons you stated above. Wouldn't go back even if I could. Using the terminal code I posted allows you to use some apps that rely on 0x0. Samsung health is one of them as I use it every day.

to be honest ive rooted every device ive had dating back to the htc hd2 lol
that's why i sent the xperia xz premium back was due to locked bootloader which looks near impossible to root
ill properly root i just didn't want to destroy any apps which made any hardware not work properly but if everything works (apart from samsung pay and secure folder) which i don't use both then should be worth the trip lol :silly:

And also I can confirm Samsung pass doesn't work also. However I never use it so that doesn't bother me. To be honest I would root just for viper4android. And I use android pay instead of Samsung pay which also works perfect

Still haven't rooted yet darn cart make my mind up I've rooted every phone I've had and it's the first thing I normally do :silly:
Does anyone think there will be more knox apps coming out which if knox is tripped we will be missing out on
Or what if Samsung make a few more apps go through knox like s health or iris scanner then we would be stuck then lol
I don't know miss the good old days where you could just go back to stock no worrys

I don't think they will release anything else knox related. At least not for the s8 anyway
S health and iris scanner work perfect now after root, they won't implement them into knox status don't worry.

Thanks I'm going to have to root I miss it too much I've given it 3 weeks and I've never used secure folder or Samsung pass so I won't miss them and Samsung pay although i haven't used I will miss lol
Isn't android pay ment to be better anyway?
Thanks again

I had to root for viper4android amd I'm not running renovate ROM and it so much better than stock.
In my opinion android pay is better and it's supported in many places. But that's my opinion.
If you root I recommend rooting with magisk. So you can use magisk hide and modules. Good luck and post here if you need any help :good:

Root again

Good day.
Even though i will lose warranty, i'm thinking about rooting my Exynos Galaxy S8.
From what i have read in some post, Samsung pay, SHealth and secure folder will stop working with knox tripped.
Don't care about Samsung Pay, as it is not available in my country, but the other two apps, is it possible to make them work again somehow? Maybe with Magisk?
Thank you.

As far as I know there is a way to make it seem like Knox is enabled using it but I'm not 100% sure

On batman Rom s health still works fine . You have no chance of using secure folder with root
