Just incase anyone wants to know I just flashed bate bones rom from the dev section and now sel8nux is now permissive so I guess I cam flash older firmware via odin?
[Galaxy S 4 General] tech_head:
Is it possible to re-flash back to stock and *NOT* have that flag set?
[Galaxy S 4 General] Beefheart:
There appears to be crossed wires here and a grey area that needs clarifying. You continually mention rooting when the primary issue is non-stock firmwares, which, like rooting, are entirely software based. For example, are you claiming a Galaxy S4 with a faulty home button has to be repaired by law if it's returned with CM10.2 on it? And what about the Knox flag? Are you saying Samsung are breaking the law by refusing warranty on a phone with a 0x1 flag? Because it's been confirmed they're doing exactly that.

to mee it looks that it checks if the kernel is secure, if not you warranty is void. so thats the reason why you, well voided your warranty

Adobe ImageReady

seriously?
[Galaxy S 4 General] MattBooth:
That is exactly what I'm saying :)

As the EU directive and legal advice around it says... If you encounter a problem with the hardware (WiFi, modem, display or buttons) and returning to a fully stock ROM doesn't fix it then it is a hardware problem and they have to honour the statutory warranty (which is the one they involuntarily provide).

If the KNOX flag is only for KNOX and they offer a warranty on KNOX voluntarily then they can void that if they please, same for any kind of warranty outside of your statutory rights. But your statutory rights cannot be affected.

It's the same as a shop that states "no refunds" on items that, by law, are covered under statutory rights. Many will not challenge it and seek a refund. The store knows this so they put the sign up...

If you look on Samsung's website for warranty you won't find any direct text saying they void warranty on flashed phones because legally they can't do that. But repair centres are like those shady shops and will try it on to charge you money for profit.

Also when it comes to "Abuse" of a device. If you OC your GPU or CPU and burn it out from ovetvoltage... They can tell. It's quite obvious once you look inside the device. You would get denied and they have evidence of abuse. That sort of thing.

I'm posting this with the hope someone can use it to argue a warranty case and win!
[Galaxy S 4 General] bungadudu:
I know many cases in which the warranty was denied because the phones were rooted/the counters weren't reset. And in cases of obvious hw faults.

Also I remember one month ago when I went to a service with my s4, after acknowledging the problem, they asked me if I'm rooted "as to not have any problems".
[Galaxy S 4 General] nEUTRon666:
I still don't get it 1000%. What exactly does a Knox Warranty Void do exactly? Besides showing that the warranty is void, what does NOT work afterwards (besides downgrading the firmware) ?
[Galaxy S 4 General] alf69mi:
Anyone tried to downgrade from a new knox rom to a non knox rom using Heimdall instead of Odin?

Maybe Heimdall is able to do that... just guessing...
[Galaxy S 4 General] MattBooth:
Yes, like I said, they try it on. Some people in service centres genuinely think you aren't entitled to a warranty if you've rooted. The fact is, they're wrong and more consumers in the EU should be turning around and fighting it.

very good video lol true tho.
[Galaxy S 4 General] Mastiha:
Sorry if this has been posted before but I'm still not clear.

If I have a handset that was purchased from a local Telco (in my case Telstra in Australia) and I use ODIN to flash a fully stock ROM from the UK for example, will it flip the KNOX VOID warranty counter?
[Galaxy S 4 General] NaveenKumarXDA:
Yes. It will turn to 0*1 if you use odin
[Galaxy S 4 General] somator:
as long as you flash after 4.3 leak if i understand correct
[Galaxy S 4 General] Brendo:
So, so far this is correct?

- New bootloader includes Knox switch (not a counter!!!!)

- Knox gets triggered if downgrading when using new bootloader (odin is only way to downgrade)

- Knox gets triggered if using unsigned recovery/kernel

- Knox is not triggered by root

- Continually upgrading with stock firmware keeps value at 0

- Flashing firmware without bootloader stops knox switch being implemented

- Downgrading bootloader keeps Knox switch

- Currently Knox switch does not impact any software (other than not being able to use Knox mode)

- The only way to view Know value is in download mode

Would just removing the line from download mode make it appear legit?
[Galaxy S 4 General] NaveenKumarXDA:
Rooting will trigger Knox too.
[Galaxy S 4 General] unlockingsky:
Love this idea tricking a technician using visuals. But Knox will always be there.

Instead of removing it, why not make it a static line always 0x0 . Rofl
[Galaxy S 4 General] AdamLange:
Assuming that knox flag can be set in various cases, can we now clearly say that flashing custom rom/kernel is increasing the flag?

It looks like samsung started to be non-developer friendly .. :/

[Galaxy S 4 General] dimkit:
Some saids that rooting will trger the Knox void someother says NO .

Can samobody responsible say the truth about this for the latest leaked 4.3
[Galaxy S 4 General] s_vohra:
I think Knox will end up being a huge success for samsung especially to get into the corporate game where earlier BB and now iPhone is leading by a fair margin... as for us.. the XDA'ins (probably not even 1% of the whole lot) who want to root and play with the phone... I guess soon google nexus devices will be the only option remaining...
[Galaxy S 4 General] humdrum2009:
hmm

Thinking of buying note 3 but this alarms me
[Galaxy S 4 General] treyzerofive:
Brand new Galaxy Note 3, freshly rooted ONLY. Knox 0x1. Yes, simply rooting flips the switch.
[Galaxy S 4 General] szczeslaw:
You're right, that it'll probably be huge success for them in corporate world. And to be honest it seems like a nice feature after all.

Let's wait some more time, until we have better understanding of KNOX and the way it works (bootloader, the flag).

But my understanding right now is, that you're safe as long as you flash ONLY stock Samsung ROMs that were published AFTER MH8. So when flashing from MH8 to MI1 (and other roms with KNOX like MH6, MHB) and other way around you're safe. This actually makes sense, as possibility to flash older ROMs, without KNOX would compromise security and would deny whole sense of KNOX.

You're also safe untill you flash stock kernel, recovery and bootloader, that was digitally singed by Samsung. For now only way to root KNOX-enabled device, without triggering the flag, is to flash pre-rooted stock ROM.

So in other words (for now): root possible with pre-rooted ROMs. Custom kernels, recoveries etc. not possible without triggering the flag.

And flag leaves you without warranty and KNOX feature, but other than that perfectly usable device. So as long as you don't care about KNOX and warranty (i.e. you have insurance) you can do whatever you want as it was until now. If you need KNOX and/or warranty, you're limited to stock ROMs, but root is possible.

Can someone confirm if my understanding is correct?
[Galaxy S 4 General] NaveenKumarXDA:
Why don't people understand : root not possible without triggering knox .

Whatever pre rooted firmware will trigger due to hash mismatch.

SU will trigger knox.

Original firmware flashing with Odin will trigger Knox.

Only way to not trigger is update through upgraded firmware & via kies.

Thanks.
[Galaxy S 4 General] DjeMBeY:
Latest update....

It's really confusing because I'm getting latest reports from people who are using my Pre-Rooted ROMs and have KNOX 0x0!!!!

Look at this guy, he is using latest JB 4.3!

There was another person who claim that the same thing happened to him..

Those guys had old-NON KNOX bootloader installed, then they flashed latest XXUEMI8-BOOTLOADER-FREE and then they flashed bootloader from MI8 on top.... KNOX WARRANTY VOID is 0x0 and they are using pre-rooted, KNOX FREE FW!! Unbelievable! :)
[Galaxy S 4 General] szczeslaw:
For now people are trying to gather us much information as possible.

As you can see, according to DjeMBeY and some others, it is possible. So don't be so sure, you're right.

Also i have seen numerous reports, that flashing stock ROMs with Odin does not trigger the flag, if you're flashing STOCK AND post-MH8. Flashing pre-MH8 and custom kernels, recoveries and rooting via CM-Root triggers it.

I'm trying to get this right, but as you can see there are many different versions so it's not so easy...
[Galaxy S 4 General] s_vohra:
Dont believe anything till it happens to you :p
[Galaxy S 4 General] STreeTNerD:
expect reasib

yes you are correct, but messing with the bootloader i.e installing CWM trying to downgrade it will trigger the knox, i can confirm this, i got the knox 0x1 but only when i installed philz recovery.:(
[Galaxy S 4 General] clonednull:
afaik it depends on the current running bootloader used when flashing.

well as they had the old knox-free bootloader prior installing, the knox flag should be save BUT now they have the new MI8 bootloader you wrote. I'm afraid the knox flag will be set when they try to upgrade/downgrade to non signed fw as now the new bootloader will set it.

Just a personal assumption (hope i'm wrong).

DISA Information about Samsung Knox ^^
[Galaxy S 4 General] Lurking_Grue:
Not cool.

It does show who they are trying to protect here. The idea of Knox secure boot is to prevent malware and other attacks on the OS. If you can't secure the bootloader you can't fully protect the OS but what is telling here is that turning it off voids the warranty.

Imagine there is some malware that reboots the phone and infects the bootloader to just fully take over the phone. The end user goes to get the phone repaired and they say "Sorry! Your warranty is void... tough luck."

It's obvious they are not trying to protect the end user here but lock down the phone from the end user. Otherwise they would offer a way to turn it off and a way to wipe the phone back to 100% factory defaults without getting into voiding here.

Not cool.
[Galaxy S 4 General] daraj:
So If I root, it will trigger Knox and voids warranty and Knox will never(ever) work again?????

[Galaxy S 4 General] spinky360:
Yes ... i was ... and after 3 days they called me to come back after the phone ... i gone and that guy told me ( they give me a paper to ... i made a joint from it :D ) ... : Warranty void caused by unauthorized software.... So i exit from the shop ... and ups ... my phone dropped on the floor so they had to come with the dustpen to get it :)) ( so like that i made a claim for insurance ) :)))
[Galaxy S 4 General] tech_head:
I wonder if that will fly here in the US.

Unless they can prove the modification was related to the failure they cannot blanket void your warranty.

An unrelated button failure, at least in California (US), would not be an invalid warranty claim due to knox = 0x1.

We'll see how this goes but flashing firmware via ODIN triggering knox plain sucks.
[Galaxy S 4 General] SuicideFlasher:
Samsung just enjoys messin' with our minds. Unauthorized software =/= broken hardware, statutory warranty cannot be denied by law, WE are the ones holding the knife's handle, not them. But they like to make us think otherwise

[Galaxy S 4 General] Hawke84:
I've seen this discussion go round many times before in the Asus Transformer Prime forums where the only way to unlock the bootloader was to use the Asus tool and void the warranty. Asus refused any hardware issues including some that seemed to be common problems. Basically we may well be right but does anyone have the money to hire people to take on Samsung and their army of legal people? Thats what it willc ome down to in the end and we will be the suckers stuck with a broken phone :(

[Galaxy S 4 General] kasakka:
I'm still on the MGA firmware. Rooted, with Philz Touch recovery. Device status is official everywhere. However, my OTA updates don't seem to work (clicking "Check for updates" in settings does nothing and neither does enabling auto update), I'm thinking it might be because I ran the TrulyClean hardcore version.

So when the 4.3 update comes around, I'm thinking of going back to stock and doing a more careful Truly Clean this time (as it apparently doesn't require root or custom recovery).

Considering OTA is not working, what would be the best way to update to 4.3 without triggering KNOX flag? Should I just download the official firmware and flash via Odin or is updating via KIES the way to go? The goal would be stock, unmodified TouchWiz 4.3, don't care about root or losing all my data.
[Galaxy S 4 General] joecool666:
i moved from gt-i9505. on to Sony xperia z1 today super fast device.

"Samsung" theirs is a lesson to be learned here.guys good look with Knox hope yes get it sorted out might be back "IF" Sammy sort there s**t out. regards Joe.
[Galaxy S 4 General] chickentuna:
You're on MGA which doesn't have the knox flag trigger yet. If you flash the leaked 4.3 version via odin, you won't trigger the knox warranty void flag because you came from a "non-knox" bootloader.

Now once you're on a KNOX enabled bootloader, you will trigger the flag if you attempt to downgrade the bootloader, root, flash a custom recovery, custom rom, custom kernel and god knows what else. So far those are the things that I've gathered that triggers KNOX Warranty Void there maybe more so be warned.

BTW if you want OTA's best way is to stay on stock without modifying/uninstalling those system apps.
[Galaxy S 4 General] Arjav23:
how to download samsung knox?
[Galaxy S 4 General] MattBooth:
Why flash and then use OTA anyway? Just wait for someone to make a flashable zip of the latest firmware. You'll NEVER get the boot loader then. My S3 is still on the release BL because I never used Odin for firmwares. Using Odin has never struck me as a good idea anyway.

The issue here is Samsung's future devices will ship with this and that's a problem.
[Galaxy S 4 General] dratsablive:
How can you tell if you have Knox installed? I got the Google Play edition of the I9505G.
[Galaxy S 4 General] _Sofos_:
Check download mode for a Knox flag, if you don't see the Knox word then you are safe.

Search a little bit more next time.

Btw, ok what we know so far is that we can't reverse 0x1 since it's hw related.. has anyone searched tho if it is possible to avoid triggering it? I mean, since it's software related at first, can't we somehow find the responsible files and have a look?

Incase the above method failed, then i am sad to tell you that there is a long process that is probably going take more than an hour to complete the downgrade process.

First of all, remember that when you upgraded to 4.3, you also upgraded stuff like BL(bootloader), AP(formerly known as pda which can be downloaded from this site), CP (modem of the phone) and finally CSC. So, the trick is to download the BL of 4.2.2, AP(PDA) of your region, CP of your region or your carrier, and the CSC of your region. Trust me, finding these stuff can be hard depending on the popularity of your region and the popularity of your carrier.

Hopefully, you were able to download all the above mentioned stuff. Now go ahead and flash these things with odin. Also note that wiping the device with the stock recovery ( vol up + home Key + Power button) might be necessary. While flashing with odin, DO NOT CHECK ANYTHING APART FROM AUTO REBOOT AND F. RESET TIME.

OR THE EASIEST IS PROBABLY TO WAIT FOR THE OFFICIAL RELEASE AND THEN FLASH IT WITH ODIN. YOU CAN DOWNLOAD THE OFFICIAL RELEASE WHEN IT IS AVAILABLE IN THIS WEBSITE ANYWAYS

splitting the firmware? will this work?
[Galaxy S 4 General] dratsablive:
Well when I get into download mode, the text at the top of the screen is too small to read. Any images of what it would look like?

You need to check what firmware version you're using (Settings -> More -> About). If it's anything newer than MGA it seems you're out of luck.
