Hey,
I wanted to de-brand my phone from carrier's rom, and i put MGA from this forum (pre-rooted version). I didn't know that in two very small OTA's i would update to MH8 since there were no description to any of them, so i'm now on MH8 unfortunatly.
In Download Mode i have official mode, KNOX Warranty Void 0x0 (so i have my warranty still, right?) and now i want to know two things:
1. How can i root it withouth having 0x1 flag or any other problem? Is it even possible?
2. What triggers that KNOX flag? What to avoid etc.? I want to be as cautious as i can so i wont lose my warranty. (at least till somebody figures how to disable/downgrade knox/bootloader).
If you try to root your phone then the knox flag will turn to 0x1. I do not know what triggers this flag. But I saw a post in google+ fron chainfire there is nothing you can do if you want to return your phone in full stock with warranty because of knox flag. I rooted my sgs4 and I flashed an aosp custom rom and recovery but now I am in full stock and the knox flag remains 0x1. Triangle away is not a solution for that. Just give developers some time to figure this out.

Yea, i saw same post on his account, just couldn't find any list of things that sets that flag to 0x1. And i do value my warranty more then root a little bit. Good thing is that KNOX is being deployed to more and more roms and phones (not that great for them actually) but this should mean that there will be more devs to look at this problem and there should be fix sooner. Hope some1 will do his magic and be able to reset this, as its just software, i don't belive it can't be cracked.
Thanks for answer!

Alright, where to begin.
I've owned quite a few Samsung phones by now and I've rooted every single one of them and installed custom recovery and ROMs. But with KNOX on the S4 this has made me unsure...
What will happen to my device when I root it now? I figure it'll trigger the Knox flag to 0x1. What are the drawbacks of that? Will it affect the function of my device?
And is the rooting procedure done as usual with Odin like on the S3?
And maybe most of all, is it worth rooting the S4 and installing custom ROMs?
Many questions, but I haven't found any real answers to any of them...
Nothing will happen to your device when counter z 0×1
Drawback z you'll void ur warranty & youll not get official updates if u r on I9500.If ur on I9505 then triangle away can solve both problems.No function gets hampers until you really mess with ur phone but that's after root
Yes the procedure z same
Well if ur on I9500 then there r only customised stock version nothing much only debloated or deodexed.If ur on I9505 then definitely worth it

What happens when you actually get Knox flagged to 0x1?
You basically lose the ability to install Knox softwares, and your device will be flagged as 'insecure', which means if your company allows employees to bring their own device to work for accessing corporate emails etc and they use knox to keep security, your device will not allow this. However, you will still have the ability to use future samsung firmware releases even though you have the knox flagged.
How do you trigger Knox?
You still can root your phone with CFautoroot, but that will trigger knox to flagged to 0x1. If you try to downgrade your firmware, knox will also trigger to 0x1, therefore, once you upgrade to new bootloader, there is no way to go back to old bootloader without knox. (I would suggest if you do not want knox, but you want the new firmware, you've got to manually flash the modem.bin files using Odin)
Lastly, there is still a big question mark as to whether Samsung will actually service devices with knox 0x1

I agree with you except last words. Modem has nothing to do with knox... flashing a different modem version from rest of FW version (ROM and CSC) will probably give some data or voice problems, and he will still have the same android 4.2.2 version....
What I suggest if he wants last FW, is just flash it, root it, delete all knox files, assume he will have knox bit activated, and enjoy it.
Hi guys, I have a Galaxy S4 I9505, and I've been reading for a while about KNOX "Counter". I want to root my S4, but I want to know if I root or unroot my KNOX Counter will increase from 0x0 to 0x1? And it is so, I can reset that Counter to 0x0? Because I don't want to lose my warranty.
Thanks in advance!
These are really basic question and have been asked a 1000 times already. If you really did read about Knox you would have find those basic anwsers. I don't think you have read much about Knox. There is a big thread here about Knox. You find your anwsers there.

my friend, the link below is described completely the knox...

its no problem if your device has not guaranty.
Ya I think that your device gt i9505 support triangleaway so you can reset your flash counter.

samsung gt i9505 support triangle away, and reset counter.
But counter Knox, you can not reset.
just to clarify for you...."flash counter" is a counter that increases each time you flash a rom or whatever. the know 0x1 is a flag which doesn't continually increase, it will either be 0x0 meaning that it's a stock/official system, or it will be 0x1 meaning that the knox flag has been tripped because some part of the system has been modified (e.g. flashing custom rom or recovery, or rooting etc).
so if you want a totally official/full warranty guarantee, don't modify the device in anyway. if you've gone past your warranty date or just don't care about it then you can root/install custom roms kernels and recoveries, but this will likely trip the knox flag if you have the kitkat bootloader.
I got my i9505 unlocked without any warranty. Its running stock I9505XXUGNE5. What could be consequences if I root my device?
Would I be able to receive OTA updates after rooting?
Do I need to delete all KNOX related stuff after rooting? Because I've heard that CF root method does interfere with KNOX in such a way that you get random reboots.
Firstly you have a i9505 unlocked so there are no problem for root.Secondly if u will root u can't receive ota updates and when you are trying to root thay ask you stop the knox...after cf-rooted you never install knox again...because your flash counter start counting...but your device supported triangleaway so u can clear all your counter and u also back to official.

What I understand from your post is:
1) I can't receive OTA updates after rooting, so how will I upgrade to latest stock? Using Odin?
2) If I use CF-Root, KNOX will be deleted and I should not install it again, right?
3) Knox counter can be cleared using 'triangleaway', right?
So it means there is not much to lose other than KNOX? My last android phone was Xperia U and when I unlocked its bootloader its DRM keys were destroyed which means no more Bravia engine and XLoud. I hope nothing like this happens with S4.
Yoy can get ota update via kies and when you clear you flash counter u can install knox agian....and not much thing u lose except knox.

You should read the first thread in the Q&A section about Knox. You are getting things mixed.
If you flash a good custom rom, you really don't want to go back to stock. Don't ask what a good rom is, because that's all about personal preference.
you're confusing some stuff.
the Knox warranty void counter WILL BE TRIPPED if you'll root your device, hence, your Knox app will not work on your device.
there is no possible way to reset the Knox counter as for now.
You won't get OTA updates, because your phone will change from Official status to Custom, though with xposed module: wanam xposed, you can trick your device to be official, and still get updates via the option there: fake system status.
you can always flash a new rom with odin, even stock roms of course... but you will have to root the device again.
triangle away will reset the flash counter, but it will not reset the Knox warranty void counter.
you can see that counter in download mode (pwr button+volume down+home button)
Knox warranty void: 0x0 (not tripped) 0x1 (tripped)
Sorry for the nooby question, but what does OTA mean?

No, no updates but you can restore via odin of you decide later you want them. For knox phones if you will be going custom then I recommend to do so sooner than later, I've got this crazy hunch......
I had number of issues with wifi just breaking intermittently on a knox bootloader gs4 once I went custom. I would have to power down for a few minutes and then power back on to get it to come back up! it's odd because with time it seems that this issue goes away on its own for good once the custom rom and kernel has had a chance to settle, which takes a few days... The only reason why I think that this would happen is because knox can't be disabled completely and perhaps the knox bootloader is looking for some kind of knox response from the wifi driver which isn't present because it's not availble in custom rom and perhaps there is a fail count that need to be triggered before knox bootloader just give up and disables this check completely? Anyone else's thoughts on this?
But beware, for me, this issue comes back once you re-flash a new custom rom/kernel and then you have to wait it out again...
So it seems knox is still active somewhat even though you have a custom rom/kernel installed. The other reason why I recommend switching sooner rather than later is this approach, I would imagine allows for more time to react and fine tune software to work with different bootloaders Eventually as kernels and custom roms are optimized the code should speak better to the knox bootloader.
If your always upgrading then you may not be allowing enough time for open source community to react and mature to the unforeseen changes that appear in new bootloaders.
I have another gs4 no knox MDJ bootloader and have no wifi issues at all, it solid! but this may be because the community has had more time to talk to and MDJ bootloader.

Triangle away can reset your phone to Official status and allow you to get OTA's again as well.
Was looking at some random threads and found this:
http://forum.xda-developers.com/showpost.php?p=60775776&postcount=5
Any tutorial on how to do this?
Also is there any value in keeping KNOX 0x0 now that my warranty has expired? It's not that the S5 can use Samsung Pay right? It needs that MFE(?) chip?
Thanks

If you have KitKat on your phone, you can follow this guide.....
http://forum.xda-developers.com/showthread.php?t=2843044
You will be able to towelroot your device and flash a pre rooted lollipop firmware.
If you want to flash and root the latest Lollipop firmware for your device, you need to towelroot while still on KitKat, and then use Flashfire to flash (and root) your chosen LP firmware......
The Flashfire thread will help guide you....
http://forum.xda-developers.com/showthread.php?t=3075433
Concerning the value of keeping Knox at 0x0, that depends entirely on what you want to do with your phone......
Yes, Knox has a direct bearing on warranty, but as you said, your warranty has expired, so that doesn't matter.
It also has a bearing on whether you can use your device on business (enterprise) networks.....tripped Knox = no access.
If you decide to go back to full official, tripped Knox has been known to impact OTA......Tripped Knox = no OTA Upgrade
Don't quote me on this last one, but I *think* I've read that tripping knox breaks S Health functionality......I may be wrong on that one though.....

Hey all, it's been a while since my rooting days but I wanted to check in and ask this: Is there a simple way that the manufacturer can tell if you have rooted the phone? I ask because I'm a verizon employee now and they're more strict than my previous employer was, At&t. I know samsung used to have a counter on some of their devices but wanted to check in with today's current root methods. And if there is a way they can tell, can you reset it to zero after flashing through odin or another method?
TIA!
There is Knox warranty void which is tripped when root and when tripped it's permanent. There is no way to undo it other than changing mainboard.
Knox is an efuse, hardware based thing.

But what about the exynos version. is the knox flag still there if you go back to stock?

It is. But it does not have an efuse so could potentially be reversed. However nobody has found a way to do it as of yet.

everytime you'll flash something, the knox counter will be from 0x0 to 0x1, which means your warranty is void.
Up to now there is no known way to turn it back to 0x0
