Root only should be ok

Ok lads: rooting does not afect knox FLAG (sorry for capitals, i'll explain later why i used them).

Installing custom recovery will trigger the flag.

Kingo app - i would not trust them. They are talking about knox counter. It is a FLAG (now you know why capitals) it is either 0x0 either 0x1, no 2, 3....

HTC has BL locked. They are helping you to unlock, but you have to accept that the warranty is void.

I think Sony is the same.

All knox thing is explained very well here.

A simple search on google explains what Knox is.

Thread should deal with how to bypass knox, not with sammy policies.
[Galaxy S 4 General] IberianPrince:
I'm afraid rooting does affect Knox flag. I used Chainfire CF Auto-root tonight, it went perfectly, but Knox is now 0x1... I'm not at all bothered, but it's proof that just rooting isn't Knox safe.

vroot working perfect, but i need install supersu and delete superuser. thanks
[Galaxy S 4 General] chubby65:
All you have to do is install superSU as system app and vroot disappears
[Galaxy S 4 General] hawkn:
You can install custom roms etc. only thing changed i knox flag and new bootloader, it has been mentioned several times I think.

I have tried several roms and kernels after knox flag changed on my phone.

And yes you can root the phone, np.
[Galaxy S 4 General] darkrevlis:
yes, i know thanks partner
[Galaxy S 4 General] :
Useless thread is useless, the posts I've read are not near Knox so I would say lock this thread or write to op because my opinion this thread has gone from Knox to Samsung turn us down and apple involved. Nothing more then useless thread, op should make a new one and this should be deleted. Cleaning this mess up who wants that?

Regarding Knox telling that it's might not be an efuse etc, well it's told on their site that if the device gets tempered with knox will be useless. And they also said that it can be a problem for end user in companies since they might root their devices so I'm 100% it's not an efuse. But again nothing has been proven. But according to Sammy and their Knox site, it's a kernel related thing but that is not however the only issue. It's recovery as well.

Ok backing to Knox thread... is there any way to delete this from my device? I mean this Knox app. I dont need it and it frustrates me because when I turn wifi on, I get a notification saying about some app trying to do something blah blah.. I have already turned off notifications from it but I would really like to get rid of this app.
[Galaxy S 4 General] nitrate:
ROOT your device, install Titanium Backup, run the app, search for "KNOX", disable (freeze) any results, reboot your device (just to be sure). Have fun. :)

Knox is not only an App. Knox becomes a major part of your TW Android OS. Only Solution: went over TO AOSP, say goodbye to Samsung TW Firmwares.
[Galaxy S 4 General] Tanis64:
Don't see that in that way, sure Knox isn't just a App, there are some services running also, but all of that is to 'secure' the Knox Container. Touchwiz is also be running without the Knox stuff (works perfect for me)

But you need a rooted device to get rid of that Knox stuff.

SELinux and the Bootloaders are not TW.

Threads about Vroot AND Kingo are being banned from XDA because they possible contain MALWARE!! Vroot sends large amount of data to chinese servers. Format your device and reflash firmware.

You don't want malware to have acces on a root level!! STAY AWAY FROM VROOT AND KINGO UNTIL MORE INFORMATION IS AVAILABLE.

I REPEAT STAY AWAY FROM THOSE ROOTING METHODS

Is it not possible to boot into a second kernel?

Have a stock kernel and a custom kernel working together! It was achieved on Sony Ericsson x10 quite some time ago, which allowed phonbe to boot a second kernel. This would allow us to have a custom kernel running the tweaks without touching the stock.

This is the reply I received from a developer who used it

" To run one kernel over another kernel, you have to have stock original kernel to be preemtible, which is probably so.. And the main thing..you have to ha splboot module, being built for your kernel..search over github.. If I'm not wrong, DoomLord had a repo for it.. Then you just make a script making a trick with changing service binary.. Most cases.. Chargemon is used since it's first service which runs before androit boot.. So you insmod splbood and hope that new kernel will boot..."

Hope this help although I know this is not easy but it was achieved before and maybe we can work on it it for gs4.

Some guy wrote similar question on our finnish forum and other had a solution to him. The message comes from your Facebook account. You have to browse with your PC and set your Android account trusted list. So, no KNOX this time. ;)
[Galaxy S 4 General] Michal Z.:
Thanks, but I dont have facebook app installed :) Anyway I would like to get rid of it if it is possible :p

I wrote an email to Samsung Poland Customer Service, I asked exaclty about knox FLAG, they replied after 2 days. And they said me this (translation from polish): "I understand that you are asking about Knox App. Using it will not void your warranty":laugh: Of course I send them another message, still waiting for reply.

In meantime I had a live chat with Samsung US. The first guy said that they can't give information about devices that were not bought in US :|

So I tried second time with different nickname (I picked some random english name - Greg :P) and this time it connected me to some lady. At first she told me that I should call to specialists because she doesn't have information about knox flag. And right after this she said this:

So I get some information, but I'm still not sure about it :/

Hi, I asked the polish head-PR guy from KNOX solutions. I asked him different question: what would void my warranty? That what he responded:

1. Flag 0x1

2. Custom ROM

3. Flag + Custom ROM

4. Root

So ANY breach of the system in the phone.
[Galaxy S 4 General] testadeferro:
Tell the man he's not over the EU law! Lol. He can say what he want. At the end he must to give the warranty be free will or by court decision.

Send him a copy of the EU directive and ask him id the points he mentioned remains.
[Galaxy S 4 General] My1xT:
[MENTION=4506118]testadeferro[/MENTION] you might be true with the EU directive, but not completely. the EU warranty by law applies to the seller (whether it being amazon, your phone company or your electronic shop) the 2nd warranty from the manufacturer is optional and is played by their rules so they can refuse anytime...
[Galaxy S 4 General] testadeferro:
Not at all my friend. In the first 6 months every defect that shows up is ever conected to a build defect and the manufacturer must replace. Even if you use custom rom or root.
[Galaxy S 4 General] Kwbmm:
I don't really care. If the EU laws says rooting and modding your android phone is totally legal, if it stops working before 2 years warranty are gone, it must be repaired/changed without charges.

If the manufacturer refuses to do so, he's breaking the law.

In this 2 years of warranty either the seller or the manufacturer has to supply a working phone free of charges.
[Galaxy S 4 General] My1xT:
where is it exactly stated that the manufaturer must replace? as far as I know the EU law warranty is for the seller. and I pretty dont confuse it because in German we have 2 different words for the warranties ("Gewährleistung" for the EU law warranty and "Garantie" for the optional one from the manufacturer).

and the 6 Month thing also applies only to the seller warranty by EU law, but not completely. exactly said is that in the first 6 Months the seller must prove that the user made the fault of the device, but since it is mostly a too tedious task for them they'll straightout replace it. after the 6 Months, YOU must prove that the defect was there all along, which is a hard task...
[Galaxy S 4 General] testadeferro:
That's why samsung repaired my s4 with brocken screen membrane. With knox 0x1 free of charge. And the personal from samsung told me clearly that knox 0x1 don't voyd warranty. Only you ll not be able to use knox software anymore.
[Galaxy S 4 General] Kwbmm:
That's not the point. I don't really care if the phone is repaired or changed or whatever. And I don't really care who pays for it ( seller or manufacturer ). During this two years if it stops working, it has to come back to me totally fine and without any charge.

To refuse warranty Samsung must be able to prove that your device stopped working due to your modding ( flashing, rooting etc.. ). Knox flag isn't enough: it just proves you made something you shouldn't have done, but not that your phone isn't working due to this.. but if you brick your GS4, that's a different story.. :rolleyes:
[Galaxy S 4 General] chubby65:
There is far too much confusion about knox but i for one don't trust anything Samsung has to say

They've been caught out too many times now
[Galaxy S 4 General] testadeferro:
Look friend, the EU thing is a directive not a law. The directive says what you point. Then every country apply the directive accordingly to his own law. Here in Portugal it is like i told you. Six months for the manufacturer the rest to the seller. I have vodafone contract. I dont thimk samsung will refuse vodafone repairs or aplly this seller warranty. I don't imagine what happens if vodafone strikes to sell samsungs. Once i had a problem with Samsung (phone broken after 3 repairs). Vodafone gave me a new one after samsung service stay quiet (still wait till today for a answer). And vodafone told me who rules. They say "if they don't replace you the phone they will replace it to us, because we have louder voice with them". And even I didn't buy the phone from vodafone. They gave me a new one. So samsung can build is sand castle behind knox but maybe other companys can stop selling them.

On thread http://xdaforums.com/showthread.php?t=1856327

I read interesting about cpu internals.

It seems that smc is an interface to nv. Nv means to me non volatile.... nv shouldn't be write once.

However it seems difficult to downgrade bootloader without jtag due to signing at boot loader level. Is might be possible on exynos that perhaps use less security.

In that thread the OP sais that Samsung service reset the flag to 0x0 and did a downgrade in a few minutes.

So, is not sure if Knox is hardware or software (in my opinion). Maybe something hardware that can be reseted with one samsung's trick that only (for now) Samsung knows?

P.D: Asuming that post is true... If not...i'm sorry
[Galaxy S 4 General] dpeddi:
Samsung can do everything... they have signed tools... signed loaders and signed whatever... we need other leaked software. Maybe we can reset knox bit with vulnerability

Weird, not so long ago (but before 4.3 and knox) I have read an article in which Samsung told that custom roms will not void warranty at all. I have a friend who is junior programmer at Samsung and he confirmed it. And now they are saying something opposite... I don't know what to think anymore.

P.S. Yes, I have already asked my friend about knox flag and he replied: "so many men so many minds". So he also does not know...
[Galaxy S 4 General] Swizzy88:
This, albeit most likely an automated message, is what I got as a reply this morning from Samsung UK regarding KNOX and warranty. Note that it doesn't specifically say the KNOX 0x1 flag voids warranty, eventhough I specifically mentioned the KNOX flag, it doesnt even mention KNOX at all, nor in the link he provided me with.

Even though they can probably not prove it but once that 0x1 flag is set they just treat the phone as 'rooted and custom ROMed'.

Shame that Samsung is always so damn vague and slow regarding statements... I expected more after investing £500+

Sounds like a void flag makes the device's warranty void even under this law as we'd have to prove its Samsungs fault and that would be costly.

[Galaxy S 4 General] omniwolf:
while it sucks if you void your KNOX warranty on your own phone, I really don't think Samsung are going to change this. They have DoD approval now with KNOX, and as the administrator of mobile phones at my company, I can completely understand KNOX. I don't want the employees at my company walking around with rooted phones, bypassing Exchange policies without me knowing. Exchange policies are there for a reason - if the phone gets stolen then at least we know there's a passcode to stop the data on it from being stolen, or we can be sure the device encryption is enabled, or that we can remote wipe it, etc etc.

With root you can bypass all that, and suddenly the company secrets aren't secure anymore. With KNOX, I can be sure that if an employee is dumb enough to root their phone, I will know about it, because KNOX won't work.

Now, having said all that, of course I want it both ways. I want to be able to root my phone, but know that none of my employees have.. but i suppose that won't be possible :)

Hope this explains some things, and shows you guys that complaining about KNOX isn't going to help. Samsung have it working exactly the way they want to, and in fact they're being quite nice - even if you void your KNOX warranty, you can still go ahead and root and flash stuff on your phone, it just means you can't be trusted with KNOX stuff, which is the truth!
[Galaxy S 4 General] DjeMBeY:
Well, that is obvious but you've missed one thing. WARRANTY RIGHTS.. This is what concerns us most....

I will NEVER use KNOX for personal use so I don't give a **** but it matter to me if they start refusing HARDWARE repairs due to KNOX FLAG being set to 0x1 which would be unacceptable!!! (IMHO).
[Galaxy S 4 General] sorg:
I don't have KNOX enabled phone yet, and i wouldn't care of KNOX status as long as it won't affect the work of phone for personal usage. It's ok to not be able to use some enterprise security features like Exchange.

What i'm worrying is that KNOX can affect some other apps. For example, we all know that you cannot use wireless display feature if your phone has "custom" status. And if KNOX will affect more such non-enterprise features then most likely will think about phone from other manufacturer. If i would like to use locked down device then i would go with iPhone. If Samsung will become like Apple then it's dead for me.

Although it depend on how stupid people in service center, word warranty is not used only for "free repair" meaning.

KNOX WARRANTY VOID means that Knox service cannot be trusted on this device and thus doesn't provide warranty for security enabled apps. So, it's nothing to do with manufacturer warranty for device.

Since there is almost legal way to flash older official firmware without root or any hacks and thus void knox warranty, then there is no reason to void manufacturer warranty. But it's up to service center anyway.
[Galaxy S 4 General] Hawke84:
I totally agree with you, i dont care if it means i will never have access to Knox software on my phone i just care about harware issues usually resulting from a fault in the production process or a poor component - nothing to do with me messing about with OS.
[Galaxy S 4 General] zoomee:
Has anyone actually confirmed a warranty repair whilst KNOX warranty is set to void?

In all honesty I couldn't give a flying poopookakaa if it was just about KNOX - if it affects our actual hardware warranty thats when its time to give a crap and look at a different manufacturer. I used to love flashing my phone to the latest ROM but since MH8 came out - I ain't updated at all! - This must be the longest period I ain't flashed a new rom in ages! :(

And yes - I see what Samsung are doing here by introducing KNOX for the enterprise sector of the market, but for consumers they need to make it clear where we stand with actual hardware warranty.

At the same time, not every one is a corporate employee. As a member here previously stated, we would understand if it were implemented as a corporate policy among CORPORATE PERSONNEL PHONES but I myself am not a corporate employee. I have my own work phone and the GS4 is a personal phone. If they wanted, they could have the IT department implement the whole KNOX thing even if it was a BYOD situation, however this has been forced down our throats without our permission.

No, they are not being nice. It's basically saying someone jailed you but the jailers are being nice because they let you eat, sleep, change your clothes, and apply make up inside the cell. I'm sorry but I find your reasoning offensive. Most of the people who paid for this phone didn't know Samsung was going to implement this. It's simply evil to think that something is justifiable just because your corporation would benefit from it. What about the rest of the world? Oh wait. Who cares about them, right? They're just little people. That is just not responsible.

And the people here are actually the ones who helped Samsung and became guinea pigs for them.

On another note, can anybody tell me what firmware versions have Knox? And do all phones with Knox have SELinux as Enforcing?

I don't know if my device has Knox or not. How do I know? I haven't updated my device because no OTA has arrived for September. Last update was made on August, with the update being the one released last July, which upgraded the device to Android 4.2.2 and removed accessibility of Debug Menu in Service Mode.
