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?

[Q] Does Samsung Have the Ability to Remotely Brick Phones? Seems Like They do to me.

Well, I have a Note 3 and the only thing I have done is root it, I did not trip the knox counter, made sure of it. It read 0x0. Well today when using my phone it randomly shut off on me while browsing my email and it threw itself into a boot loop.
Nothing I did was able to fix it so at that point I went into kies and did the firmware upgrade to put it back to stock and I was quite surprised when I entered download mode. The knox counter now read 0x1. I went through with the firmware and it didn't fix it. Since the knox counter was tripped at this point I just said screw it and loaded a custom recovery on the device to wipe everything out of it that way including system and data, then tried to flash the stock rom. It didn't work.
I then tried Kies again, didn't work. How is this possible? How do I randomly trip the Knox counter doing nothing and my phone randomly bricks on me? I now am stuck with a paperweight that is out of warranty even though I made sure it was prior to doing anything.

In that many rooted with triggering the knox flag and it didn't prevent them from using their phone, that is not the issue.
You may just have a hardware issue. There are those that might be able to figure it out though.

I thought hardware issue as well, but why did it randomly trip the counter? That's why it is concerning to me.

What method did u use to root.

Root De La Vega

The only things that are supposed to trip the Knox flag with that method are:
Flashing a custom ROM will trip the flag
Flashing a custom Kernel will trip the flag
Flashing a custom Recovery will trip the flag

What recovery did you use did you wipe the system or format the system. If you did the latter you and can get into download mode I would flash the stock ROM with the pit to repartition your memory. I had to do this with my s4

[Q]Flashing Stock Rom

Hi.. i'm new to android and samsung things
that's why i'm here to ask something and hope could get a fast reply
Problem:
I have a note 2 N-7100 with 4.3 stock rom(unroot, OTA updated to 4.3 from 4.1.2)
I wan to know how to flash back to 4.1.2(4.1.1 if possible)(step-by-step)
done some searching over the net and all thread confused me
will 4.3 stock rom flashed to 4.1.2 or 4.1.1 stock will void the warranty(Knox)
What is the Risk i have to take?
Why i want to downgrade?
Crazy battery drain rate.. even when turn off the phone(1day about 8%)
Sometimes shuttering when hearing music
any reply is appreciate.. TQ

Your Knox flag will become 0*1. You can flash stock 4.1 through odin. But you will need to format your internal memory as well as your all apps will be deleted.

tq for the reply..
so.. i just need odin and the stock rom downloaded from sammobile
and i dont need any custom recovery.. am i right?
well the apps can be redownload

No you don't need custom recovery for flashing stock.
As joy854 said your knox flag will become 0*1. It means you lose warranty for ever and that you lose the ability to update the phone the normal samsung way.
I recommend to you that you try custom rom like hurricane or phoenix. I get more than 2 days battery with hurricane and note 3 apps.

So.. will custom rom void my warranty by trigger the knox?

Be careful!!
Hey man if you have taken the 4.3 update from OTA then you cannot downgrade to 4.1.2 stock because that 4.3 update came with Knox bootloader, because of that you cannot downgrade your phone from older firmwares which do not have that knox bootloader. It might brick your device mate, so just be careful man.

I am having similar issues with you, but i am not thinking of downgrading my ROM, You can solve the battery drain problem by downloading an app called Battery Doctor (tried putting a link here to it but the forum wont allow me since im a junior member, but you can search it out in the google play store) It is very useful and it helped me a lot. But after updating OTA to 4.3 I do get stutters when hearing music, a tad few seconds sometimes in between music. I wonder if there is a problem to solve this? Other than that. 4.3 works great on my GT-N7105. Thank you.

Yes, if you want root or custom rom it will trigger the knox thing

AFAIK flashing anything non-stock in odin will trigger knox flash counter. Root will be blocked by knox apps which can be disabled, but I don't think having root permissions itself would trigger the counter.
Personally I wouldnt care about the knox counter, so long as the issue was hardware related I would play ignorant; there's no way they can prove your device wasn't sold to you with a voided counter. That's not to say they'll validate your warranty, but with a bit of a fight the correct result would me they have to honour it - but no one wants that hassle.

[Q] Modified Note 3? Won't let me update :(

Hey, everyone! I tried googling this for hours and I still haven't found a solution, so here goes:
A couple days ago, I deleted an important image from my T-Mobile Note 3 and I was freaking out, searching high and low for a solution. I read on Yahoo! answers to download DiskDigger, but the device must be rooted in order to install it. So, I tried to root my device with KINGO Root, which totally failed and then my device just went into bootloop and I thought I messed up my device for good. Luckily, on a different thread someone suggested to use the Youtube video GalaxyNote2Root made to unbrick my Note 3. (Even though it was for Note 2, it was the same concept and I did find the stock firmware on samsung-updates for my Note 3.) It ended up working successfully and then I continued to try root my Note 3 using Odin and the video instructions on xda forum (which I should have just done in the first place) and that worked successfully, too.
Now, my problem is, is when I went to update my Note 3 under settings, it says "Your device has been modified. Software updates are not available." I tried using Triangle Away (I don't know if I did it correctly) and also 1-click unrooting my device in SuperSU. I'm a huge noob at this rooting stuff, but what I gathered from all the research I did on Google, I apparently tripped "Knox". When I go into download mode it reads:
Current Binary: Samsung Official
System Status: Official
Knox Kernel Lock: 0x0
Knox Warranty Void: 0x1
So, a couple questions I have are, how do I "unmodify" my Note 3 so I can get updates? Is there a way to reset my Warranty Void back to 0x0? Will this always happen if I want to root my Note 3? Thanks in advance!

you can not revert knox back to 0x0, no method so far for this....
so you can receive updates, just flash through ODIN, the firmware ... I believe all Samsung phones and tablets will tell you about being modified for updates, if you rooted the phone.

well, you can just reodin a stock unrooted firmware, and then otas will work again, but Knox is basically always tripped.

why even use odin when you have SAMSUNG KIES. put your phone in download mode first, load KIES on your computer, then go to tools>firmware upgrade and intialisation and then follow the step by step direction.
if this helped just press the thanks button!

Can you link me to an unrooted firmware? And when I flash my device with the unrooted firmware, do I uninstall root first or will this just take care of the whole thing?

I tried unrooting the phone and it was still not letting me update because it was still "modified". I thought this was because I tripped Knox, but maybe I didn't unroot correctly??

when u flash the stock firmware in Odin it will overwrite root, so no worries. just follow the first part of this guide. obviously don't flash root, or custom recovery. just follow the first part of this http://forum.xda-developers.com/showthread.php?t=2765014
or, you could also go to a website called sammobile and download the latest ne6 firmware. The link I provided is also the latest ne6 firmware guide, and like I said just follow the guide up to the the root part and you will be good. it will over write root, and whatever else. good to go.

yea, you must of done something incorrect. now, you won't have any updates after following the ne6 guide, as you will be on the latest firmware. but if you continue to stay on it you will indeed be able to grab otas when they come. personally I would just root, stay rooted, and keep up to date with roms, and kernels, and all that crap.

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.
