Knox warranty void flag

I'm currently using stock MF6 firmware and there is no indication of the Knox warranty void flag in download mode. Does anyone know which firmware introduced this flag on the S4 mini or is it not implemented, yet? I'm asking because I want root access and need to know which prerooted firmwares I can choose from without this flag.

As far as I can tell, there's no Knox flag known on any S4 mini firmware or variant. Definitely mine has no sign of it either. And from what I read, at least ith the S4 it was never transparent, only when the flag appared could you kill it, in older firmwares no matter what you did the flag was never set until you upgraded and there was something considered wrong then.
4.4 is supposed to bring Knox for the mini so it may bring the flag, which could be easier, harder or the same to avoid as the S4, only time will tell I guess. If it's similar, hopefully enough will have been learnt by the time S4 mini get 4.4 that we can easily get around it.

@Nil Einne
Thank you for your reply. Which firmware version are you using?

(I9195XXUA)MG3 (which is 4.2.2 / JDQ39). It's currently the latest for my CSC. I may root soon perhaps using a prerooted firmware (since mine is so old) but I'm waiting to see if anyone has tried it on a 16GB version. I didn't mention before but I guess it's clear now I have an I9195 but I haven't seen any mention of Knox flag seen for any variant of the S4 mini on current firmwares.

My s4 mini (I9195) came with firmware MF7 and was upgraded OTA to MG8.
After that I flashed with Odin to MH2 (Android 4.2.2).
Thereafter I flashed a custom rom (Slim with 4.3.1).
Where and how can I see whether my Knox warranty void might be 0x1 now.
And what if I flash back with Odin to firmware MF7?
Is that still possible without a later upgrade problem?
Curious about your info.

New Rom XXUBMJ7 whit KNOX bootloader (aboot.mbn) and aplications.
After flash this Rom we have on Download Mode:
KnoxKernelLock: 0x0
KnoxWarrantyVoid: 0x0
Like on Note 3 N9005, if we flash something, customer, root, KnoxWarrantyVoid: go to 0x1 and this is not reversible.
To Root
The Root-Kit-V1 install all superuser, SU and busybox but after reboot the SuperSU can't access to system, KNOX not permit.
To solve this we must flash after, on recovery the UPDATE-SuperSU-v1.65.zip from Chainfire. After we have root alright.
My case like on Note 3:
I not need the KNOX, the phone is only for me, then after root I delete all KNOX apk + odex from system/app.
Good luck

Is it possible to go back to old bootloader WITHOUT knox?

All you wanted to know about KNOX Void Warranty 0×1
By tamirda • October 9, 2013
Screenshot_2013-02-25_11_35_AM
Recently, Samsung announced that her all new devices will get an Android 4.3 update that includes KNOX Security system. According to Samsung, these devices will get the update:
Samsung Galaxy S3
Samsyng Galaxy Note II
Samsung Galaxy S4
Samsung Galaxy Note 3 (already has KNOX Security system)
Most of the users don’t root their devices and use it normally and for them KNOX Security system is a great option.
But what happanes if we want to root our device?
Now the problem begins.
Normal(unrooted and so..) devices are flaged as KNOX Void Warranty 0×0 right from the factory.
When we flash items which weren’t signed by Samsung, it flags your device as KNOX Void Warranty 0×1.
According to Chainfire, KNOX status is indeed an eFuse. This means that even JTAG can not reset the KNOX status back to 0×0.
Some facts about KNOX status:
It isn’t possible to downgrade to KNOX-disabled firmwares/bootloaders (An attempt sets 0×1) (even though some people state, downgrade is possible when omitting the bootloader file in a firmware package). By downgrading from KNOX-enabled to KNOX-disabled firmware, your devices will be locked to installation of newer firmwares.
Let’s focus on that fact. As we mentioned above, Devices like S4, S3 and Note II which came without KNOX will get the KNOX system.For example, S4 I9505 got about a month ago 4.2.2 update that includes KNOX-enabled system(MH1). If you try to downgrade to KNOX-disabled system(MGA for example) your device will be flaged as KNOX Void Warranty 0×1 and will get a special lock – you won’t be able to update to any KNOX-enabled firmware even by ODIN. Samsung’s 4.3 update is KNOX-enabled, so if you tried to downgrade to KNOX-disabled firmware(for example MH8->MGA), you won’t be able to install 4.3 update.
This problem is only for devices which didn’t come with KNOX-enabled system from the factory(S4, S3 and Note 2)
Jeffery Butler confirmed this information:
FYI…Samsung told me that Knox warranty becomes 0×1(void) when the device with secured bootloader attempts to have non-secured bootloader. MH1 is the very first binary with secured bootloader. If MH1 is attempted to be downgraded to lower version(i.e. MGD) which has non-secured bootloader, then Knox warranty becomes void forever, and this means that the device can be used only for non-Knox device(no container can be created).
If you try to downgrade to KNOX-disabled firmware, you can’t install any new firmaware(that includes KNOX-enabled system) and use your device only with the old firmwares.
Even if you flash a KNOX-enabled firmware via odin (e.g. the latest fw) knox will be set to 0×1.
Flashing unsigned or modified images via odin will set knox to 0×1.
According to these two, flashing root/kernel/recovery/latest firmware by samsung/etc. will set KNOX status to 0×1.
Samsung stated, resetting the flag is impossible.
Chainfire confirmed that it is impossible to reset the flag.
KNOX is mandatory and can not be completely removed.
In custom roms we can remove KNOX apps, but the status remains 0×1.
Warranty Void is not a counter, it is a flag (0,1). We have never seen 0×2 or so.
Mirroring all partitions from a clean 0×0-Device to a 0×1-Device via JTAG produces an unfunctional device (reversible by restoring the 0×1 partitions on the phone).
Using JTAG or other repair tools to reset the flag is impossible.
KNOX bootloader verifies signatures of kernels and recoveries. No custom ones possible without voiding the knox warranty.
Again, if we flash kernel/recovery/etc. we will void the warranty.
This si how 0×1 looks like:
2rn7beq.jpg
This is how 0×0 looks like:
attachment.php
I guess you are asking yourself now, what the hell 0×1 means?
If your device is flageed as 0×1. you should forget about your warranty.
Chainfire and other people confirmed that your can’t use your warranty:
Worse than that, I’ve also been hearing that service center instructions are indeed that devices with this status tripped will not receive any warranty repairs. (Of course, the action they take may still depend on the service center). Their excuse is that the hardware is damaged by the owner. Seems Samsung is catching up in scumbaggery to HTC, who years ago attributed my HTC Diamond’s screen damage (digitizer detached) to the installation of HSPL
To anyone in the know it is obvious that this doesn’t really fly, and the eFuse blowing (is this the hardware damage?) is intentionally done by the bootloader when unsigned software is loaded.
If you want to read the whole Chainfire’s statement, click here.
What is eFUSE? it’s a technology that allows reprogramming a read-only memory chip in real-time, even though such chips come with hard-coded code that cannot be generally changed after manufacturing.
When flashing unofficial software on the device, the status of the system and KNOX is switched to CUSTOM while increasing a binary flash counter, which helps Samsung find out whether the device has been tampered with. However, while Chainfire’s TriangleAway app has let users switch the status back to official and reset the flash counter until now, the KNOX status is based on eFUSE – basically, once you flash custom kernels or root the Note 3, the KNOX code gets rewritten, and this constitutes hardware damage.
Well, all I can say is think twice before you play with your Samsung device. If you don’t care about warranty, and you like custom roms and cool stuff just be aware of this information and continue with what you are doing.

As you may already know, the latest Samsung firmwares came with a new secured bootloader. You can recognize it in download mode easily. It states: Knox warranty void: 0x0 or 0x1.
As for now, there is no way to reset that flag from 0x1 to 0x0.
Then I read in a comment of Chainfires post concerning that flag, that as long as you do not try to downgrade to a non secured bootloader, this flag will not change. He claims to have that information directly from Samsung.
https://plus.google.com/u/0/+Chainfire/posts
Has anyone already experience with rooting an "untouched" S4 which has the secured bootloader and can confirm or decline that?

Conclusions and Facts about KNOX-enabled firmwares (based on statements from chainfires post and it's comments above, ans based on this thread)
Not possible to downgrade to KNOX-disabled firmwares/bootloaders (An attempt sets 0x1) (even though some people state, downgrade is possible when omitting the bootloader file in a firmware package: see http://forum.xda-developers.com/showthread.php?t=2444671, not confirmed)

Flashing unsigned or modified images via odin will set knox to 0x1
Samsung stated, resetting the flag is impossible
KNOX is mandatory and can not be completely removed
Warranty Void is no counter, it is a flag (0,1) it was never seen 0x2 or so
Mirroring all partitions from a clean 0x0-Device to a 0x1-Device via JTAG produces an unfunctional device (reversible by restoring the 0x1 partitions on the phone)
KNOX bootloader verifies signatures of kernels and recoveries. No custom ones possible without voiding the knox warranty
Assumptions on how KNOX flag in bootloader works:
Some experts think, an eFuse is involved. (http://en.wikipedia.org/wiki/EFUSE). An eFuse is mostly only incremential. Even unwriteable by low level tools or JTAG. But it is still not proven, that eFuse is used.

3:Can i install custom roms?
DeepankarS said:
You can do any customization on your phone like a normal phone, but customizing it means that you have triggered the KNOX counter to 1. Thus on a stock rom you can never use KNOX if KNOX reads 1.
FYI the MK4 (bootloader) or MJ9 (babseband version) has blocked installation of any custom roms on our n7100s via odin. You cannot even downgrade to 4.1.2 official via odin, So flashing via recoveries is the only way left.
And also it is recommended that you install custom roms via Philz/TWRP/CWM recoveries to flash custom roms and everything.
Hope the lil knowledge helped.

On the note 3 it's done by special bootloader leaked by sammy. The only chance for the note 2 is if note 2 bootloader is leaked. No other way.

Nope i can't risk to send my phone (400 euro), but it looks like they have the solution.I send them mail to ask if i can pay for the file and instruvtions but no answer till now.They want 75 for the reset and 45 for express shipping end delivery.I told them that i am

And one more thing-if i send them phone i can't be sure that they will reset it instead of just replacing MB and write my old IMEI e.t.c

I-9192 official status again
i have installed a few weeks later a rooted rom from another forum, and triggered the knox to 0x01 (so i cant receive official updates from samsung)
but, today i needed to reset my phone to factory default, than i was curious to check the phone status, and for my surprise was "Official" again...
i read in various sites that the knox flag cannot be reverted... is that true?
the files i was used to root:
Odin 3.09
Kernel_root_I9192.tar
SuperSU_1.41.zip
the only bad thing is that i lost my root
anyone have the same result just reseting the phone?
thx and sorry for bad english

Soooo. As far as i know the knox wont get updates from Samsung and Block using knox app? And what features are lost from a triggered knox? I flashed the original firmware again and all its ok so far. Theres any blocked feature that o didnt realize?

Need help
I've a s4mini 19192 and today I flashed samsungs official KitKat update to my phone... I tried to root it like I rooted the 4.2.2 update... But can't do.... Then I decided to downgrade to the old version 4.2.2 but odin says can't.... And fails... Someone can help me?

Is it possible to check when the flag was triggered?
I was sold a GN3, in witch the KNOX flag was already set* and I'm trying to avoid a situation in witch the seller will say that I've set the flag.
* not checked beforehand - my mistake - but still I can return it or get a discount under the law

hello..just got the s4 mini dual sim 9192... 2 days back..i was on 4.2.2 indian firmware....checked download mode and it said knox 0*0...now i flashed the 4.4.2 firmware downloaded from sammobile via odin and when i recheck knox is gone....!!!!
just said binary and system which changed from official to custom once i rooted it with CF-root method(nothing else was working...saferoot/towelroot etc)..and as i seem to have read that flashing stock rom reverts these back to official...is it true?
and does this mean that my knox firmware phone has been converted to a non-knox one after kit kat upgrade?
please anyone let me know..thanks

@Fataz bro i have a few questions
I'm currently on FNE2 stock deodexded custom rom with a FNE2 bootloader, when i go download mode it says "KNOX WARRANTY VOID:1"

P600: A small observation and a couple of questions (Knox 0x1, TriangleAway, etc.)

I've noticed that there's been some discussion about the new knox bootloader in regards to rooting our device. Now, when I boot my I9505 into download mode I get this wall of text in the upper left corner telling me "knox warranty void 0x1 blah blah" and likewise when I boot into recovery captain obvious knox pops up in the corner reminding me that I'm running a custom recovery.
Now that I have rooted my tablet and flashed TWRP via Odin I have yet to see a single sign of that infamous knox flag. Download mode - nothing, recovery boot - nothing... nothing except my settings telling me my device status is custom, and even that can be spoofed via Wanam Xposed.
Am I missing something or is the knox bootloader simply not present in my firmware version? (XXUBMJ6 NEE/nordic countries)
Also, has anyone had success using TriangleAway on the P600 to reset the flash counter? Not that I currently need it, just curious..

It's weird that the p600 does not have the same download mode display as the p605. It says nothing about knox on the p600 download mode. So the guys on the other forum are confident that triangle away should work to reset the counter on p600 because it's not a knox flag. But as far as I know Triangle Away does not support the note 10.1 2014 yet. So I guess we have to wait and see

Thanks for the reply and the link.
A "warranty void etc." message has popped up in download mode as of now but you're right, it says nothing about knox whatsoever, and the strange part is is that it didn't appear until I actually flashed a mod via recovery and wiped cache/dalvik. Before that there was no message in the corner, even though I had already flashed cf-root and TWRP via Odin.

Same here. Even though there were no updates available at the time I last checked I got no warning message.
Maybe the P600 just has less security implementations than the other versions for whatever reason...

''Knox warranty void 0x1'' is the KNOX FLAG. It means that you cannot use the secure Knox container, and you will not get OTA update. Of course you can download and install new software updates.

Yes, but it does not say anything about "KNOX" or "0x1" when I enter Download Mode. I should also correct what I said in my previous post. It doesn't say "Warranty Void" but rather "Warranty Bit: 1".
ODIN MODE
PRODUCT NAME: SM-P600
CURRENT BINARY: CUSTOM
SYSTEM STATUS: OFFICIAL
WARRANTY BIT: 1​
This is identical to how it used to be on the old 4.2.2 non-knox bootloaders and it's NOT the Knox flag. It's the binary counter.

I have SM-P605. I think Knox bootloader is present from 4.3 onward. If SM-P600 has Knox app in the apps drawer and Knox security apps under Application manager then it's likely to have a Knox bootloader Tripping the Knox flag means the Knox container can never be accessed or used again but the phone/tablet itself is OK for regular use. I have not come across a phone/tablet with Knox apps and non-Knox bootloader.

Whether a Knox bootloader is present in the P600 or not, then at least the flag is not visible in download mode or during boot. Either way I'm satisfied as long as I don't have to be reminded every day that my tablet is running an unofficial kernel and recovery.

[Q] Question surrounding restoring factory and downloading official 4.3 update - KNOX

Hello!
Hope all is well. First I wanted to say i'm sorry if this is a duplicate - I searched and saw similar questions, but not exactly the same as mine .
I own a T-Mobile Samsung Galaxy S4 M919 and I had rooted it and installed a custom rom. Im having hardware problems and need to return it for repairs, so I reflashed the stock system and recovery, used triangle away to remove the binary counter, and hard reset the phone. In my download mode, my phones reads "Current Binary: Samsung Official" and "System Status: Official", as well as reads official on the device status in android so all went well.
My question is this - I got notification of a push update that is going to install Android 4.3, and apparently this "KNOX" software that I do no seem to currently have. My concern with this is that i'm reading that there is a flag with this KNOX software that is easily tripped, and once done, the download mode reads "KNOX WARRANTY VOID 0x1", which therefore voids warranties. Since I was able to get everything back to completely normal, I dont want to run any more risks since my phone really needs repairs very badly. Should I bypass this update? Though my phone is 100% official now, if I do the update, will the KNOX software catch that I had rooted/custom rom'd the phone in the past and trigger the flag automatically, or do you first have to have the update installed BEFORE you try to root it for the flag to trip? Everything is 100% stock now so when I download the update, I don't think there is anything present that would trigger anything, but I don't even have this "KNOX WARRANTY VOID" line in my download mode yet so I am wondering if I am just better off being safe than sorry?
Thanks!

It won't be tripped until you trip it so you will be OK if you update it to 4.3, But I highly advice against doing so.. Just leave it as is, and return it like that

Hello!
Hope all is well. First I wanted to say i'm sorry if this is a duplicate - I searched and saw similar questions, but not exactly the same as mine .
I own a T-Mobile Samsung Galaxy S4 M919 and I had rooted it and installed a custom rom. Im having hardware problems and need to return it for repairs, so I reflashed the stock system and recovery, used triangle away to remove the binary counter, and hard reset the phone. In my download mode, my phones reads "Current Binary: Samsung Official" and "System Status: Official", as well as reads official on the device status in android so all went well.
My question is this - I got notification of a push update that is going to install Android 4.3, and apparently this "KNOX" software that I do no seem to currently have. My concern with this is that i'm reading that there is a flag with this KNOX software that is easily tripped, and once done, the download mode reads "KNOX WARRANTY VOID 0x1", which therefore voids warranties. Since I was able to get everything back to completely normal, I dont want to run any more risks since my phone really needs repairs very badly. Should I bypass this update? Though my phone is 100% official now, if I do the update, will the KNOX software catch that I had rooted/custom rom'd the phone in the past and trigger the flag automatically, or do you first have to have the update installed BEFORE you try to root it for the flag to trip?

If you are having hardware issues and are returning the phone and
your phone is 100% stock without KNOX right now then why in
the world would you want to take chances with OTA updates or
any other updates.
If it was me I would have already taken/shipped the phone back for
repair or exchange instead of worrying about OTA updates.
Good luck!

Thanks for the advice! Download mode would be the only location of that "KNOX WARRANTY VOID" flag right? If it's not there, then as long as it states both Samsung Official and Official in download mode I should be good ya think?
Thanks!

Yes.. It will also show a message at boot

Awesome yep - no boot message I see either - boots just like it did the day I bought it. So I am pretty sure I have the firmware before KNOX came out - It has been rooted since the summer so I probably luckily bypassed the official update with KNOX
Thanks to all for your information! Im gonna stay away from the new firmware just to be safe until i get the phone back from warranty!

Hmm - things got even more interesting. So it seems when i reset everything back to stock as mentioned above, the screen flickering issues have now gone away and I am not seeming to replicate them in any way at all. Does this sound familiar to anyone? I was using a version of Wanamlite ROM before i reset everything. I am wondering if it was just the ROM causing the screen flicker and not a hardware defect.

TriangleAway still works with the KitKat KNOX enabled bootloader but the counter it resets is not the KNOX warranty flag. If you've flashed any unsigned (by Samsung) image to your tablet, including custom recoveries, kernels and/or ROM's, or rooted with CF Auto Root (which flashes a custom recovery) since upgrading to KitKat 4.4.2, your KNOX flag has been triggered and your warranty is already voided.

No you dont get my question im aware of knox and I dont want to touch it but I head that rooting changes the system status to custom in download modeand in system it changes to modified and if samsung see tht than the warranty if void so once again my question is when I root with vroot or with kingo root they both dont touch knox and than use triangle away and SET system status back to official or normal and after formating will the official or normal status stay of will it be turned back to custom/modified

I haven't used either of those rooting methods so I can't answer that. According to the Kingo website the chances of tripping the KNOX flag are 1 in 1000, but they don't mention the flash counter. OTOH, Samsung claims that KNOX can be tripped with as little as a custom kernel initialization script:
For example, some KNOX security mechanisms, such as SE for Android, will trigger an e-fuse if the system is booted with an arbitrary kernel, kernel initialization script or data, and therefore be disabled and no longer function correctly.

I know you said that you're not asking about the KNOX implications but maybe you should. Regarding resetting the flash counter and custom configuration with TriangleAway, I suggest posting your scenario in that thread and hope for a response from Chainfire, the developer of that app. If you can root with one of those methods without tripping Knox, my experience is that after using Odin to flash the stock ROM and running TriangleAway when I was using the 4.2 ROM and bootloader there was no indication on the bootloader screen or using the stock ROM that "tampering" was detected, but things might have changed with the 4.4 bootloader.
Good luck, and please let us know how it turns out.
