What's all this Knox stuff about?

Can anyone tell me what's up with this and why should I be careful about running certain ROMs? Knox counters, etc?

Ok, here are the prerequisites for not getting the KNOX POX:
#1: Don't allow the flashing of the M919 MK2 4.3 OTA update
#2: Don't Odin flash the official stock M919 MK2 4.3 TAR firmware. (SamMobile or elsewhere)
#3: Don't Odin flash the M919 MK2 4.3 NON-HLOS.BIN
#4: Don't Odin flash any bootloaders
If you have NOT done either one of those four things you will NOT catch the KNOX.
You can Odin flash the 4.3 M919 MK2 MODEM but it is completely optional.
See which one has the best signal for you.
( or keep the M919 MDL MODEM which is already in your phones.)
The phone will work just fine with either the MK2 modem or the MDL.
You can flash any cwm/twrp flashable M919 MK2 4.3 or MDL 4.2.2 zip file stock or custom roms.
If you follow these rules above you will not loose audio, signal or wifi and you will not catch KNOX POX.
Now that's not too difficult to understand right? LOL
Good luck!

Not difficult to understand at all. Thanks. I tried looking for this info on my own, but I couldn't find it.

In addition to the poster above, another way to look at it if you are simply trying to avoid getting it without messing around much:
SAFE:
1) Any ROM that is flashable THROUGH CWM/TWRP/PhilZ won't include an updated bootloader. You can install 4.3 or 4.4 and still keep your bootloader and/or baseband (i.e, MDL, MDB).
UNSAFE:
1) If you ODIN flash (meaning you plug your cable into your phone, start up Odin, put your phone in download mode, then PDA a stock FW), you WILL get the KNOX bootloader.
2) If you update through KIES.
3) If you update through the OTA (in Settings -> About Device -> Software update) .

Some people believe if you trip knox then you will void your 1 year samsung warranty. I dont think it's been confirmed. And i dont think it would matter to me since it's such a short warranty and it doesnt cover accidental damage

Ok, well I've actually updated my phone through kies (4.3) the same day it was released but I was losing signal way too often so I used my 4. 2 back up and restored it... But my flash counter was 6 so I odined and did a reset on the flash counter and then used infamous (4.3) and I'm still on MDL so how do I know if I have knox?

If you updated your phone using Kies/OTA or Odin flashed the official 4.3
firmware then you definitely caught the knox pox.
The way to tell if you have knox is to put your phone into download mode and
look at the top left side of the screen where you will see tiny blue writing.
You will see the knox status as either 0x0 or 0x1 if its 1 you have knox.
There is nothing you can do about it at the present time.
A lot of the developers are trying to over come the knox issue but so far no luck.
Even with the KNOX you can use your phone just like if it did not have the knox.
You can download and flash any cwm/twrp flashable custom/stock zip file roms
as well as any of the themes, mods and anything else requiring cwm/twrp flashing.
You can even odin flash the 4.3 official stock M919 rom from SamMobile
and it will work just fine. However you will still have KNOX.
KNOX is just another way for Samsung retailers to know if you have
messed around with your phone and gives them a good enough reason
why not to honor the warranty.
Good luck!

Well I went into download mode and I did not see any blue writing but I did see this in white: 0x30

[Q] Upgrading to 4.3... some questions beforehand

Hi there,
I haven't been updated on rooting and all that jazz in a while, so please excuse my ignorance.
I have a Galaxy S3 (SGH-T999) on 4.1.2. It's stock rooted, but I don't have a custom Recovery or anything on it. I didn't (and don't) want to trip the root counter.
Is there a way to upgrade my phone to 4.3, have root working, and not trip the root counter? (Basically, what I currently have, except on 4.3)
Also, I Googled this new Knox feature I've seen people talk about, it seems like a lot of people here don't like it-- should I not want it on my phone too?
Happy holidays,
-Proxin

The counter is easy enough to reset if still on 4.1.2, so your best bet is to install a custom recovery through odin, then flash docholiday's 4.3 stock deknoxed rom and the new modem, and the at&t kernel for working wifi. This way you can use triangle away to reset the flash counter. If you install 4.3 with 4.3 firmware, you will not be able to root without tripping the knox counter.
Hope this helps

From what I understood back in the day when I got root, if you installed a custom recovery, you either triggered the counter or lost all your data/wiped the phone. Is that still the case?
Edit: Or was it un-tripping the counter that caused the data to wipe?

If you want 4.3 touchwiz, root, and a warranty, all at the same time, don't take the official update.
Instead, flash the 4.3 ROM zip, 4.3 modem, and a compatible kernel, using twrp or cwm recovery.
If you ever need to odin, do not use any version newer than MD5 or you are stuck with Knox and can never go back.

It still triggers the counter, but it can be reset. It did not wipe my data, but backup just in case. Resetting the counter did not wipe data either. But do not update to the official 4.3 if you want to root and still have a warranty.

Uh oh. I searched around for guides on updating like you guys said, and followed the guide here which promised root, 4.3, and no root counter... and now I can't use root, even though I installed a pre-rooted ROM.
I'm on 4.3 now, but don't have the ability to use root. I don't seem to have the Knox thing though.
I don't understand why I don't have root on a rooted ROM... what should I do?
Edit: This is the exact version I used: root66_TMO_T999UVUEMJC.tar.md5

To fix root, enable developer options by pressing build number 7 times, then enable root access for apps and adb under dev options.
MJC is TW 4.3 which includes knox. AFAIK the root66 version has knox removed from the rom, but it is impossible to remove it from the bootloader.

I checked in developer options after pressing the build number 7 times, but I don't see anything about enabling root in there...
Do I have to re-root somehow? If so, will that throw off the counter?

That's why posts need read completely. It clearly says it will trip the Knox counter in 4.3 in the second paragraph of the first post under "4.3 notes" sorry that happened though.:banghead: Maybe someday someone will come up with a knox bypass in the bootloader.

I don't understand-- it seems like it says Knox is removed in order for root to stick:
4.3 Image Notes: With 4.3 images, KNOX is removed in order for root to stick. This will flag the Knox counter. Once you flash one of these 4.3 images you now have the latest factory stock bootloader, radio, etc. Flashing a prior bootloader can hard/soft brick your device. Please read and understand what you are doing.

I took it to mean root will flag the Knox counter so it has been removed from the images.
The wording is very ambiguous...
I'm pretty close to just nuking my install and starting over with CyanogenMod, not caring if I trip the counter or not. Is it possible to do so with the current setup, or will I end up with a brick/semibrick somehow? I figure I might as well, since rooting will likely trip the counter anyway.

Yes lol

"It has been removed", it being Knox haha. That's how I understood it...
So yes, it's possible to get CyanogenMod working without a brick or semi-brick coming from this version I installed?

Yes, I could have been worded better. You can flash other
ROMs but make sure they don't include an older bootloader or your device will brick from what I understand.

I ended up just saying "eff it" and hopped onto CyanogenMod. Probably tripped the root counter, but by now I just don't care anymore.
Thanks for helping me in this thread though, I appreciate it.
Take care and happy holidays.

You did trip the Knox counter.
Just so anyone else reading this thread knows, if you value your warranty DO NOT UPDATE TO 4.3 VIA ODIN . Instead, flash the 4.3 rom , kernel, and modem zips in CWM or TWRP recovery.
Do not Odin MJC (or MK4 for you T999L people) if you want root and warranty, as once you are on the Knox boot loader you can't go back.

One of the things that bugs me about forums, finding information is a pain the butt. I just want to get my device back to stock so I can get OTA updates, GPS doesn't suck, and can use Wifi. I don't care about root anymore or using custom roms. I'm learning Objective C right now to branch into iOS development. I'm sick of the Android ecosystem, to be frank.
I'm on Wicked Rom with Android v4.1.1
Baseband T999UVDMD5, Kernal 3.0.65-DeviantKernel_07
I'm downloading T999UVUEMJC_T999TMBEMJC_TMB.zip right now, along with root66_TMO_T999UVUEMJC_2.7z
Which one do I need to flash? if root66 gives me root, then cool I'll take it, but as I said, I don't care. I'll be using Mobile Odin since I'm on a mac and I sold my PC. If I need to install Windows via bootcamp then so be it, but I really don't want to.
If I need to update the rom, kernel, modem, etc all separately where do I find those files? *scratches head*

Try this post, easiest way is option 2, after installation, try to update SuperSU from Play Store and you can disable Knox when it asked.

Please keep in mind that if you already have the factory 4.3 update you already have KNOX. If you root you flash custom firmware onto your device you will hit your KNOX warranty counter and at this time there is no way to reset it. Just looking out for you since I did not do enough research before updating and am stuck with no warranty. Good luck.

i already tripped my knox.

Sad day man. I tripped mine yesterday knowing what would happen. I just couldn't stand having stock firmware anymore. Running SlimKat now and loving it. Hopefully our wonderful devs figure out how to get past this.

The sad thing about Knox tripping is that it actually diminishes functionality.
The old flash counter that was there before merely told Samsung that you have been messing with the device. Tripping the Knox counter removes potential functionality from the device. If at some point in the future you do need it, you are out of luck.
I understand the rationale behind doing it that way. It doesn't mean I have to like it...
Hastily spouted for your befuddlement

Knox is nothing more than Sammys new way of saying you unlock its yours but your warranty is gone. I hope the great minds here on xda figure out a way to reset the knox counter but Sammy obviously threw a ton of resources into this.

So I assume that Knox is part of the new bootloader? And replaces the old flash counter?

[Q] Is it possible to get back to a Complete Factory state (with no counters tripped)

My Phone is the N7105 NOT the N7100, I find it incredibly irritating and hard to find the right information having these two phones merged into one forum. Is it possible to get my phone which is on android 4.3 back to a complete factory state with no counters tripped so I can send it in for warranty. I currently have 7 binary counts and 1 knox count. A simple yes it can be and a link to a thread that can help with my device would be useful.
I have tried using Philz recover and auto CF and methods along those lines but they do not seem to be working for me.
Thanks in advance to anyone that can help, it is much appreciated.

You can turn back the binary count with triangle away, knox count no.

Afiak you can reset the binary counter but at the moment there is no way to reset knox or downgrade the bootloader on the n7105 yet. Dr Ketan is your best bet for help
Sent from my GT-N7105 using XDA Premium 4 mobile app

well that sucks as my knox counter was 0, then tired to downgrade to so I could root n reset the binary counter (i have no idea of my logic there) and obviously tripped the knox counter. So I could of used triangle away on 4.3 and not tripped the knox counter>?

I think so. Triangle away works on 4.3 now I'm pretty sure. I'd try asking Dr Ketan for advice. You can change the bootloader on nearly every other variant so it must be possible on the n7105. Just need someone to figure it out. I've been trying to do a wifi patch for the n7105 but it's bootloader is different to most other versions

Hi guys has anybody come up with a method to downgrade the n7105 boot loader from 4.3?

[Q] M919UVUEMK2 Rooting Questions!

Hello All,
I'm currently running CarbonRom on my GS3 (d2spr) but I'm sick of Sprints terrible service so I purchased the SGH-M919 from a T-Mobile store last night and I'm really stuck. Out of the box it's stock M919UVUEMK2.
1. What are my chances of rooting and flashing recoveries, ROMs and kernels? I checked the guide and it only supports the M919UVUAMDL firmware.
2. Is it possible to downgrade to M919UVUAMDL?
3. I absolutely loathe TouchWiz so should I return it to T-Mobile and order the Google Play Edition online? (not crazy about white electronics)
Any help would be much appreciated. Thanks.

You don't lose any changes of rooting and flashing, even with the newest NB4 update.. Just flash a recovery with Odin and flash a GPE ROM or aosp/CM.. You will however trip the Knox counter

Its not as bad as they make it seem unless you care about warranty, which it technically voids if you trip it

There is not any performance issue with Knox. It is just an eFuse that Samsung put on the phone to record if you ever installed a non-stock recovery. It gets tripped and no one has found a way to reset it back to 0.
Also, no one has said that Samsung or T-Mobile has not performed warranty work if it has been tripped, but that they MAY not do service on it.
Reading more about it, it seems that the Knox counter may be more tied to Enterprise security, so that an Enterprise or a shop that has BYOP, can check that, and then shut down the phone if it gets tripped. But, can't be sure of that either. It just seems to be there right now. Not sure what they are really doing with it.

Thanks for the insight. I chose the S4 because I figured it a much more mature device in terms of development. I got worried since I paid full price for the phone and did not want any complications.
