[Q] Knox warranty void - Galaxy S 4 Q&A, Help & Troubleshooting

Does Knox warranty void = Device warranty void
Who and why decided that the one equals the other?
The warranty void flag is for Knox, and it could only mean that there is no warranty for this piece of software if you downgrade your devise.
Some lawyers here?

Whats wrong with the other knox threads?

I think the words "warranty void" are pretty clear.
I also think that the manufacturer aka "Samsung" is the one that decides.
My opinion is Samsung are sick of noobs who keep playing with their phone without knowing what they are doing stuffing them up and claiming warranty when there is nothing wrong with the phone.
Disclamer these are my opinions and beliefs.

I think the
KNOX Warranty Void Flag (KWVF) is exactly that what it says
The Warranty for the SECURE System (KNOX) is voided
So you can't use the secure KNOX Container anymore
KNOX was build for Enterprise and BYOD (Bring Your Own Device)
When the Device is compromised by Root or Custom Recovery then this warranty for a secure Device is voided.
Before KNOX is starting / opening the crypted KNOX Container the KWVF is checked.
If it is triggered (0x1) the KNOX denies the access to the KNOX Container.
If not so Samsung can't sell KNOX as a SECURE System.
I don't think that the KWVF alone can void Device Warranty,
Maybe some Samsung Service Centers try to act so, but i think in Europe this will be against law.
On the other Side there are Flash Counters / a warranty Bit and eMMC Burst Mode:
Here I fully understand Samsungs effort to deny warranty if device is bricked by flashing anything to it.
A lot of noobs flash nearly everything in the second it was uploaded.
A lot of them don't use the brain or are to lazy to read the Thread ( or others) before click on the Start Button in Odin.
Such (mostly Softbricked) Devices going under warranty to the Samsung Service Centers cost a huge amount of Money to repair (reflash) for Samsung.
Thats a fully normal (and leagal) way that Samsung try to push down that costs by denieing warranty for such Devices.
What if there will be a way to reset KNOX? (I think thats only a question of time!)
If this happens the KNOX is unsecure and worthless in Enterprise use.
So Samsung and Developers will start a long-lasting ping pong game.
Instead of this Samsung should build in a Method (in Stock Recovery or anywhre else) that can do a KNOX Warranty Flag reset of the cost of totally wipe the phone including internal SD and Knox Containers.
So a once compromised phone can be reset to a normal state.
Regards

Thanks for the profound answer @Tanis64.
That's my understanding too, but your answer makes it clearer and easier to use it as a legal argument.

yep, that just about covers my feelings on the matter too

Samsung knox and root?

After reading about the new knox security features do you all think it will be harder to obtain root? It sounds like this feature locks the bootloader. Any insight on this?

Knox is B2B only which means it only applies to devices companies purchase and provide to their employees. And there's a remote companion component necessary for it to be implemented. I'd expect it to be locked down tighter than Fort Knox (get it? ) with little or nothing an end user can do to a Knox device except play with their partition. I know for sure they can't add/modify/delete any apps or settings on the Knox side. It's probably overkill for most of the Fortune 500, and there are other less rigid ways of controlling remote devices, but it will have great appeal for government use and for companies that require security clearances and handle sensitive data.
Exactly! Knox for B2B only.

Samsung trying to snatch the BlackBerry crown and win lots of government contracts I reckon
Thanks for the explanation on it. Just had me kinda worried about that feature.

I don't think so its necessarily B2B My AT&T Galaxy S4 has a Knox apk on it and according to the Knox web page the chain of trust can be changed after a device is bought. So Someone can Buy their own device then place on the business network and due to corporate rules get their device locked down.
Since My Bootloader is locked and Knox can lock the bootloader I can only assume until I know otherwise that AT&T is using the same Knox methods to lock my consumer device.
Samsung has Rollout Firmware Updates to the S4 I9505 where KNOX is fully activated, Bootloader changed and SEAndoird is enforced.
So this is a mess for rooting.
But it seems that chainfire has hacked this again in CF-AutoRoot and SuperSU (1.60)

[Q] What effect does Knox have for rooting the Galaxy Note 3?

What effect does Knox have for rooting the Galaxy Note 3?
It will permanently disable KNOX.
Is that a bad thing?? I know next to nothing about Knox, but my N3 will be here tomorrow and I'm wanting to root it.
i have similar questions.
So much threads just for questions, #Neo3d how bout trying to ask other questions in one thread instead of making heaps of threads cause to me it seems there just attention threads just to build up replys

Knox is a secure container that is supposed to be hack proof... It is generally NOT used by the stand alone consumer and is targeted more at businesses... Remember, if you use it and something happens to your phone you are pretty much NOT gonna be able to retrieve anythng in the Knox container.
However, once you root your phone, Knox can't be run as there is a security hole if you give root(system) privileges to any non Samsung approved app...
Unfortunately Samsung forced this POS down our throat and are using it as a way to deny warranty claims - Knox warranty void...
It also tries to police what can or can't be used, there were problems with messaging apps at the beginning because of application rights.
These seem to be getting fixed but it another step on the road to us being dictated how we use our devices and not allowing us the freedom to use them as we want...

Best Info on KNOX warranty I've seen

So, I actaully spoke with KNOX support today(not Samsung tech support) and asked them about whether installing a custom ROM would indeed void the hardware warranty on the device. Here's the first response I got:
Dear Patrick,
Thank you for your reply. There has been a lot of discussion regarding this matter and it will be ultimately up to the Samsung support center to determine whether the device will be covered under warranty. Since it's difficult to cover all the possible issues resulting from rooting, Samsung's official policy has been that if the device is rooted and if the device malfunctions due to rooting, the warranty will be void.
This is in response to the question I have abou what to do if I receive a device from insurance that already has the KNOX counter tripped
Unfortunately for the second case regarding the mobile device insurance company, the policy still remains the same. Technically the warranty bit should never be tripped if the device is loaded with the proper Samsung approved OS in a proper manner. If the device is returned to you with the KNOX warranty bit tripped, then we suspect that the device may had been refurbished unofficially.
Best regards
Steve

I think this is going to be as good as it gets
"and if the device malfunctions due to rooting"
good info. as always this will come back to whether Samsung believes (demonstrates?) that the warrantable problem is caused by the rooting. Hardware faults would be very hard to prove of course (screen, buttons, etc), however I'm sure that they would always say that software problems are caused by rooting. So, to my way of thinking, rooting does not "void" the warranty in total - it makes it more likely that Samsung will refuse a warranty claim, particularly for software problems.

[Q] What are the repercussions of having KNOX tripped?

What does it do, other than void warranty?
Knox has secure containers where it keeps your private data separate than corporate. That's useful if you are in BYOD scheme. Once you trip Knox you can not use its features. More info is available on Samsung Knox mini site. I'd suggest you take a look and see if you will need any of the offered features or not.

Thanks. I don't think I need any of those features. Personal device. Uni student.

Let's try to kill Knox counter ??

Hello
Do you remember, some months ago when a developer had successfully found an anwser to the Knox counter reset ?
Samsung Galaxy Note 3 was running on a Exynos SoC, same as the Galaxy S6 (edge), so I think structures might be the same thing.
Why not try to create a patch to reset Knox flag at its original state ?
I'm sure it's possible, and as we says in my country : "impossible isn't French" ^_^
your warranty is only 1 year anyway, so by the time people cracked the knox counter your warranty has already expired... and the reward isn't worth the effort, and in some regions this might even be illegal as you will be defrauding the manufacturer, so I think knox counter will always be with us in Samsung devices from now on.

I'm not sure it is possible. It is quite possible that the Knox "bit" is actually a fuse that the system blows when non-standard software is run. In that case the only way to "reset" the counter is to replace the chip housing it (or effectively the entire system board).
Well,in the S2,Note 1-2 ,etc ERA the Knox was on the software side. First version .
Nowdays its a little bit on the hardware side. Its impossible. I mean,you d waste more than 1 year to crack it. Its not worth it.
