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

Downgrade from 4.3 back to 4.1.2

So I did this a couple times now first by accident, then on purpose. If you want to go back to 4.1.2 from 4.3 all you have to do is use Odin. Flash stock 4.1.2 onto 4.3 you get an error "unsupported firmware" then put your phone back into download mode (volume down+home button+power) next flash CF-auto root. After that you can boot into recovery (volume up+home+power) in recovery format everything factory reset, format cache. Last reboot your phone it should reboot into 4.1.2 I think that is how I did it if I remember all the steps right. Feel free to ask questions I don't always explain myself very well.

So, has the 4.3 bootloader (which has KNOX) been downgraded to 4.1.2? And KNOX is removed?
What is the status of your device right now in Download Mode?

More importantly, if it has the non-Knox download mode (without the whole 0x1 tidbit), does reinstalling the OTA (which would have the Knox download mode) show 0x1 or 0x1 ??

the million dollar question.

Well to be honest I think the answer to both questions is No. In download mode after I did the ota knox bull has been there. I actually only meant to use auto root on my 4.3 but knox kept on screwing up the root and su would fc. I figured if I started over and used auto root on 4.3 right after flashing rom with odin without letting phone boot and that worked I have 4.3 rooted with su and custom recovery (cwm). So no I didn't find a way to get rid of knox completely. Just a way to go back to 4.1.2 from 4.3.

You need to update supersu when rooting on 4.3. Otherwise it will forceclose.
Sent from my SGH-T889

I'm still thinking that Knox will need to be patched/disabled during the root process (or something along those lines). Samsung claims the the fuse trigger is only capable of being triggered from 0x0 to 0x1 and not back again. So to me the answersolution probably will have to come with segregating Knox from the bootloader/system altogether. It'd be funny if devs could use Knox against itself by segregating it in the very "sandbox" it creates, if that makes sense

Any 4.1.2 stock tar or was it a specific one? also is there only one version of CF auto root?

Help please!
Hello All.. After over 5 years of flashing I think I have finally bricked my device.. I am normally great with directions and the forum however I think the latest 4.3 update got me twisted up. Odin'd back to stock and upgraded OTA. All was well.. Then I attempted Chainfire's CF auto root.. All was well and I froze on a phone call.. I battery pulled and now I get "Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again".. I tried to go through Kies emergency recovery and it wont accept my serial numbers.. I called t-mobile they told me I need to bring it to a smasung dealer to get "flashed"... I'm at a lost now.. One thing else is when I access download mode I see this Knox Warranty Void : 1.. Does this mean I'm done? I've been trying to read up on this knox and it seems scary to say the least.. yet nothing I read has helped me.. After hors of searching and missing the football game I decided to look to the forums.. Any help is very much appreciated. :crying:
I tried to ODIN back to stock with several .tar files (UVBMB4 and UVALJ1) it fails and shows unsupported version(in red) on the device:crying:

sir, i'm new to this forum and here's my situation:
i have a sgh-t889 t-mobile locked, stock 4.1.2 (UVBMB4) which i erroneously updated to android 4.3 via kies.
i cannot do network unlock because based on my forum searches, only android 4.1.1 can be network unlocked via the method outlined here:
http://forum.xda-developers.com/showthread.php?t=2176721
i have odin 3.07 and have already downloaded the following roms:
1. T889UVUCMK7_T889TMBCMK7_T889UVUCMK7_HOME.tar.md5
1.68 GB (1,814,261,839 bytes) (1,771,742 KB)
2. KIES_HOME_T889UVALJ1_T889TMBALJ1_260018_REV04_user_low_ship.tar.md5
1.25 GB (1,345,341,538 bytes) (1313811 KB)
can i reflash my sgh-t889 to 4.1.1 safely and do my own unlock?
thanks for any clarification and more power.

If you can flash back to 4.1.2 from 4.3 then you can flash back to 4.1.1 from 4.1.2. That's how I unlocked my phone.

thanks for the suggestion but the 'com' portion of odin 3.07 would not lit up and the following ROMs could not be flashed:
4.1.2 = SGH-T889_TMB_T889UVBMB4-teshxx.tar.md5
4.1.1 = KIES_HOME_T889UVALJ1_T889TMBALJ1_260018_REV04_user_low_ship.tar.md5
the 'com' portion of odin would only lit up if the sgh-t889 is connected to the pc under usb mode. it would not lit up under download mode.
i have this other 4.1.1 ROM which i did not test yet as of this moment as i'm waiting for more information:
4.1.1 = root66_root66_TMO_T889UVALJ1.tar.md5TMO_T889UVALJ1

just for clarification, you were on stock 4.1.2, updated OTA to 4.3, then re-flashed successfully to 4.1.1 via odin, then flashed OTA 4.3?

4.1.2 to 4.3 via kies to 4.1.1 via odin to 4.3 via kies
re-reading this thread: http://forum.xda-developers.com/showthread.php?t=2176721

i used this ROM = KIES_HOME_T889UVALJ1_T889TMBALJ1_260018_REV04_user_low_ship.tar.md5
re-flashing to lower version via odin 3.07 was successful.
i did the unlocking trick as outlined in this thread: http://forum.xda-developers.com/showthread.php?t=2176721

Since you already tripped the knox counter, you can flash the VALL4 tmobile modem and try the same unlock steps in the thread.
The specific modem was all that was required to unlock the t889. I unlocked on 4.1.2 only flashing the older modem and following the unlock steps.

[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.

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.

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.

"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*

current rom i'm using is the infamous alpha s4 12.04 12.14.2013 (release date i think) --> http://forum.xda-developers.com/showthread.php?t=2362636. after flashing this rom, there are countless issues regarding loss of data, call drops, etc. prior to flashing the full 4.3 M919UVUEMK2 tar, my issue was more on the side of not sending and receiving mms w/o having to disable wi-fi (after flashing 4.3's modem.bin to change baseband from MDL to MK2). unfortunately, this didn't really help me at all, honestly, til i read:

i've also searched about getting KNOX'd. sure i was scared about voiding warranty, because i have this s4 for about 3-4 months only, lol. in any case, i downloaded the full 4.3 M919UVUEMK2 tar file (read this post from same thread above: http://forum.xda-developers.com/showpost.php?p=48669487&postcount=4399), and flashed it, rooted my s4, flashed philz recovery (the latest), clean/wipe phone, and re-install alpha s4 12.04. after doing all of this, i was worried again about getting KNOX'd so i double check and triple check and no KNOX -- me very happy. the only downside is that triangle away doesn't seem to work on MK2, so my counter is 4 and, yes i can send and receive mms w/o having to disable wi-fi . i will constantly test calls on this rom to see if there will be any drops or what not, so we'll see how it goes.
hope this isn't TL;DR lol. i'm still very new at this rom scene, and i hope to get better as a user because i can't program worth a damn :laugh: also, i hope that this will help or lead others to help them in finding their solution in other 4.3 roms out there.
peace

To answer your question, the mk2 is a firmware version. But if you break it down you have a mk2 boot loader, mk2 modem, etc etc. The firmware contains all these things and their all mk2 version. So you can have mk2 firmware, mk2 bootloader, mk2 modem/baseband etc etc. Mk2 is just the firmware they came from

yes. don't have another phone to take a pic of my sgs4 in it's download mode; but on the top left of the screen, in download mode, it tells me this:
ODIN MODE
PRODUCT NAME: SGH-M919
CURRENT BINARY: Custom
SYSTEM STATUS: Custom
CSB-OEM_CONFIG_LSB: 0X30
WRITE PROTECTION: Enable
ofc, please correct me if i'm incorrect about these things. i'm assuming that from this pic on this thread, http://forum.xda-developers.com/showthread.php?p=47878403, indicates the phone is in download mode and that that is where to check for KNOX. again, correct me if i'm wrong
thx.

Hate to break it to ya, but that is not the mk2 Knox enabled bootloader.
If it was , under system status it'd say Knox kernel lock 0x0 and under that Knox something else 0x0.
The link you got the firmware from, which was on Jamesons AFH, must of contained the mdl bootloader

Yeah , just saying you have the modems and running mk2 based. But that's not the mk2 bootloader.

You avoided the real question by Vigz !
Show us the line in your Download mode that the "KNOX Warranty Void" is: 0x0 & not 0x1 !

Yeah. No Knox flag. Personally I don't care if I trip it. I pay insurance for the ability to "lose" my phone if some catastrophic event happens to it Ahaha

i thought i did reply correctly. like previously stated, i don't have another phone or camera on hand to take a pic of my Download mode, what i listed is all that i saw on when i'm in download mode. so, there is no KNOX Warranty Void: 0x0, or 0x1 on that screen.
pretty much like shiny said above, the mk2 tar file that i flashed from jamison904 did not have the 4.3 bootloader in it; and it seems to be a good thing lol. hope that helps.

I am not sure that it did not trip the Knox security..

The only way to find out if it 0x0 or 0x1, is to install the Knox app itself !
Yes, it will let you install it to a certain point & when you try to set it up (if your Knox is tripped) it will tell you that it can't be installed !
Then you can uninstall the app.

There is no much discussion on this application (for none rooted or custom ROMS), but if you manage to not trip the Xnox security flag, this app is somewhat a nice to have.
It creates a second UI (User Interface) on your phone with ability to customize it completely differently from you regular settings with some Samsung (I know, many will considered it as bloatware) specially design apps for Knox.
It is useful especially, if you intend to keep some concealed info, documents & videos...etc.

Not true.... The flag is displayed in download mode. Just like the flash counter. So to see if you tripped it you do exactly what the op did. Boot into download mode and you'll see 2 lines regarding knox with values. 0x0 if not tripped 0x1 if tripped

My response was directed to the user with a diffrent boot loader !

The user that couldn't have the same Download menu because of his none a MK2 bootloader !
If you would read my previews post carefully you would see the your answer is redundant (you repeat what I already said to the user).
What I meant is, in case you don't see the Knox warranty void 0x0 / 0x1 in your download menu, then the only way to find out, is to install the app !

If it's not displayed in the bootloader, said user doesn't have the Knox infused bootloader. So there's nothing to check. I think you're referring to the other flag. The flash counter. Which isn't the same thing as the Knox.

My question really is how did this happen? I thought if you flash that Tar file you automatically pickup the 4.3 baseband and knox with it. Could this be remaining from you updating just the modem? For me the problem is that I cannot seem to update the modem to mk2. I do not really see any advantage of locking the bootloader with Knox and if my screen stops working stupid T-Mobile will find a way to refuse to fix the phone!

How'd he flash 4.3 and avoided the Knox bootloader? Package he flashed wasn't official. Either the aboot.img was removed or was replaced with mdl aboot.img

Do you think you can point me to a package like that where I will not pickup the bootloader? I have been trying to just update the modem using odin and keeps failing. Maybe flashing a non knox tar file will do the trick to get everything to work properly so that I flash 4.3 finally!
Maybe the OP can also post a link to the package he flashed using Odin!

[Q] Need advice resetting to stock 4.2.2

I'm planning on upgrading to another phone so I'm trying to get this counter on my phone reset to 0, then unrooting.
Right now I am on the latest version of Insanity ROM Android 4.3 MK2 Baseband .
I tried resetting the counter using TriangleAway earlier, but I noticed I needed to be on a stock Samsung kernel.
So I found one (and this same thing happened when I tried to flash a stock rooted ROM with MDL) on XDA directly for the T-Mobile S4, only to find out that after flashing, it wouldn't get past the black screen after the SGS4 logo comes on.
Luckily, I restored back
I know how to unroot and everything I just want to ask before I do this,. Can I go ahead on using Triangle Away on my current rom? And then do the unrooting process?

If you took the OTA 4.3 you are Sol. If you still have the MDL bootloader you can Odin the MDL stock image then root and triangle away and then unroot. You will be good to go then.

No, I never had it updated when I bought it from Tmo as Android 4.2.2 . So you're saying with even with the current custom 4.3 Android & custom kernel that I have right now I can Odin the MDL? (Unroot, Root, TriangleAway, unroot?)

Yes. If you never took the OTA and only flashed the mk2 modem you can absolutely Odin the stock MDL ROM and root, triangle away then unroot (in that order) You'll be good to go then. Just make sure you're binary found is at 0 by booting into download mode when you're done.

I'm having the same problem when I got my s4 I didn't know anything about Knox or all the other headaches that come with rooting this phone!! But me being me as soon as I opened the phone I updated it to 4.3 then rooted it not knowing I wouldnt be able to return to stock! Even tho I did backup my stock rooted phone my phone will not let me restore to it so I've been stuck on beanstalk 4.4 but really want to go back to stock rooted cause of the camera!! Haha.... I'm new to the s4 so I'm still learning more about it I had an s2 before this and that was all cake walk flashing and what not. I just want to know if Odin is an option for me to return to stock or not?? I think I backed it up through lies before ota 4.3

From what I've read in other threads you cannot downgrade bootloaders so if you took th OTA you can't go back to 4.2. From what I understand it will brick your phone. If you are already 4.3 and rooted you have already voided your warranty. You may as well Odin the stock 4.3 and root again so you can flash other Roms since you are stuck on 4.4.
