[Q] How to know what rom is knox free ?

Hi,
after reading a lot of thread here, or in android developement, about galaxy note 3, I am wondering if there is any way to know if a rom is knox free or not.
a lot of time, it is not clearly listed in the thread.
I saw some post saying that if you use odin mobile, or odin on PC, or rom without kernel, or rom without boot loader etc...
but I find easily some information which says the opposite (specially odin mobile, which I bought, and tell clearly when I launch it that it can trip knox counter)
my galaxy note 3 N9905 is under 4.4.2, xxxUGNG1.
I rooted it without modifying knox (I checked it, it is not set to 01, it is still = 0)
I would like to undertsand what I can flash without "any" risk, and whant method to use :
odin on PC ? custome recovery ? original recovery (renaming the rom by update.zip is working, no ?)
no kernel ? with kernel ? no bootloader ???
thanks for any help to understand.

ROM has nothing to do with KNOX trigger. You strike the flag only if you flash custom recovery or custom kernel.
You need custom recovery to install custom ROM. Or Mobile Odin Pro. The only way to install custom ROM without affecting the KNOX flag is by installing via Mobile ODIN Pro and NOT installing custom kernel, should the ROM installation include one.

Hi,
thanks for the feedback.
I try to have more information please.
let me sumarize your answer, and add more question :
I have a N9005, under stock rom, 4.4.2, xxxUGNG1.
note : I never launched knox in the device. I don't know if it change things or not...
I can flash a rom, using mobile odin pro, and not set knox flag to 01 if the rom do not contain any kernel.
I cannot flag any recovery at all : if I do it, knox flag will be set to 01.
if the rom I want to flash contain a kernel, I have to remove it from the package (or may be mobile odin pro has a setting to load the package, and not flash the kernel) ?
I cannot change the modem, for the same reason than for the recovery, right ?
if I want to flahs CM11, I will set the knox flag to 01, in all case, because the kernel need to be changed. right ?
so, the result is :
if I want to play with my note3 (play for me is testing CM, or all rom not starting from a samsung rom), I will set the knox flag to 01... right ?
thanks for any feedback

It is no guaranty that custom rom will work with the stock kernel.

T320XAR1ANK1 Extracted Stock Firmware

I usually do this for the Note 3 I have, and it comes in really useful for devs, those running other roms, etc, that just want to upgrade the modem/wifi, bootloader, and CSC without messing with everything else. It's also handy to replace the stock kernel if you need it for whatever reason (towelroot anyone? ). Since I recently picked up a Tab Pro 8.4 from swappa, I did this for mine to do the upgrade, and thought I'd be nice and go ahead and share the extracted parts for everyone else to enjoy.
Here's the MODEM+NON-HLOS (both together and as separate files), Bootloader, Kernel, CSC, and Recovery I extracted from the new T320 1NK1 Firmware. In desktop Odin 3.09, Kernel and recovery would go in AP. Modem + NON-HLOS goes in CP, Bootloader in BL. If you flash the bootloader separately, make sure to tick the box that says bootloader update.
Bootloader:
CSC: http://www.mediafire.com/download/dje1u61d8pk8dou
Kernel: http://www.mediafire.com/download/bi2jsdcub9c9k82

If you have trouble getting the bootloader and/or Modem to stick, install "Triangle Away" by @Chainfire and follow the directions to reset your counter (even if it says zero), then boot into download mode, and re-flash them with Odin and they should stick (WARNING: Triangle Away WILL TRIP KNOX).
NOTE: It has also been noted by several people that booting directly into download mode from a powered-off device and flashing the BL/Modems will make them stick as well.
To verify, you can download "Phone Info - Samsung" and make sure that all applicable items say either T320UEU1ANK1 or T320XAR1ANK1 (Bootloader,, PDA and CSC). NOTE: Not all functions of this app work for our tablets, but most do.

I'm planning on rooting and going back to an old Kernal. After rooting, I am going back to the NK1 kernal but I'm on T320UEU1ANK1. Can I go back to NK1 kernal using the T320XAR1ANK1 kernal you your post or do I have to find the T320UEU1ANK1? I know you have the full T320UEU1ANK1 image but I just to ODIN T320UEU1ANK1 kernal.
Thanks in advance.

Just a question but I believe it does not affect root, if I were to install the modem/firmware I would not lose root correct? Also, if you were to flash the whole package, does towel root or manual root (think I used Hashcode script vs towel root) does the new firmware allow root access? I don't believe these devices are as locked down as a carrier device, but just wondering! When people refer to firmware and modem, what part is the firmware on this actually? I see the modem, but is firmware part of the NON-HLOS or what ?Thanks!
Edit: Seeing another thread, seems CF Auto-Root will still work, answering my above questions, thanks and sorry for not fully researching first!

My Tab Pro 8.4 (Wifi) shipped with the latest firmware already installed. I didn't want to use CF Auto-Root because it trips the Knox flag, so I flashed this kernel (http://forum.xda-developers.com/showthread.php?t=2786800) and then was able to use TowelRoot, which doesn't trip Knox.

Nice job. I upgraded using the full image, downgraded the kernel, rooted my T320, restored your kernel. Very simple and all worked great. Thanks for this.

@toastido Could you give me a link to Kernel BNI1 (Portuguese version) plz?
Thanks in advance.

is there a risk of bricking phone (odin) ? (Samsung Galaxy s3 neo GT-I9301I) - root

Hi guys, i was thinking of rooting my phone with odin but i'm afraid i might brick it ( CF-Auto-Root )
so.. is there any one who used odin and it worked with him without bricking his phone ?
oh and i forgot to mention that i have android 4.4.2 kitkat
because when i use the normal way to download supersu and install it i get
-----
"There is no binary installed, and SuperSU cannot install it. This is a problem!"
"if you just upgraded to android 4.3, you need manually re-root consult the relevant forums for you device!"
edit:
i rooted my device with odin and there was no problem

Download SuperSU via this link: http://download.chainfire.eu/641/SuperSU/UPDATE-SuperSU-v2.40.zip and flash it with your custom recovery.

[Q] Rooted S4 GT-I9505, How to update from 4.2.2 to more recent ? - keep root

Hello,
I'm using a SGS4 rooted since more than one year and a half (odin, flash a small root bin file if I remember well, flash counter set to 1, no custom recovery and no nandroid backup)
Since I want to implement NFC card emulation now avaliable in android 4.4 in one of my apps, I'd like to update.
I've seen few threads on the subject, and most of them date from a long time (am I late ? ). I'd like to know how I could update normally my actual rom (provided by Orange, precisely I9505XXUAME2), or move to another slightly modified rom like the base rom provided by samsung without all these apps that you can only remove with root.
I don't want to have any data issue I've read about, I don't want to lose my actual apps and their data. (Nandroid backup then restoring apps and their data through nandroid manager?)
Also, if possible i'd like to update without losing my start screen, my parameters, etc... (in the worst case I'd re-set them manually). And finally of course I want to have it rooted at the end of the process.
In fact I want it to be just like if I had done an OTA update, then rooted it.
Also, How to update without setting the Knox counter to 1 ? (My flash counter is set to 1, should I use Triangle Away?)
Is there any simpler way than flashing the new firmware and then importing everything from my old data to the new and reinstalling the changes I made to the system (like avast & such) ?
Also, maybe there exists newest versions of the firmware, but without the new bootloader that has the knox counter ?
Thanks in advance!

1. You can't receive OTA updates if you have rooted your device. You have to flash the firmwares via ODIN.
2. You don't need wipe nothing if you flash new stock firmware. Instructions: Flash new firmware (if you don't have wifi flash it one time more), root it again then and you're done. Your data don't have to be affected (maybe you only have to reinstall some app if the data/cache was moved to the SDCARD).
3. Flashing one new stock firmware don't modify KNOX. You actived KNOX rooting your device or flashing one custom recovery. Knox: 0x1 can't be reset. Triangle away only reset the flash counter.

Thanks for your fast answer !
So, flashing a firmware doesn't impact the data.
Updating via Kies sets the Knox counter. Updating via odin doesn't ? Don't I have to do any sort of un-root before updating ?
Is there anything specific I should know about root ? Because I don't want to flash a firmware that I won't be able to root without setting the knox counter.
Also I think that since we can't revert the bootloader update, maybe i'd better not update that bootloader so that I can update future versions and root them without setting knox counter, by installing a knox-free rom even before a knox-free root is released...
Where can I find these roms?

1. Updating via ODIN or Kies don't set the KNOX counter. Downgrading YES.
2. Root dissapear if you flash new update via ODIN.
3. You can flash latest firmware and root them without KNOX. Take a look for the method: HERE.

Thanks for the answer again!
Howerver I still have 3 questions because I like to understand what I'm doing :
1. I understand the two terms ROM (OS of the phone) and bootloader (after a certain update, it adds the knox counter, and you can't downgrade it, and it also prevents towelroot from working). What is the called "kernel" ?
2. Up to exactly what version of the bootloader/rom does towelroot work ?
3. What is the difference between "knox-free" and "knox counter 0"? At the end of the method, will I have the new bootloader with a knox counter set to 0, or the old bootloader ?

2. Nobody know it.
3. - KNOX free: This therm is used for the custom ROMS normally. This mean that flashing this ROM dont touch the KNOX counter.
- KNOX counter: You still having your device in warranty if you have KNOX:0x0. You void your warranty if you have KNOX:0x1 in DOWNLOAD MODE.

So it means I'll still have the new bootloader ?

How to flash prerooted ROM to new android 5 device without root and keep knox 0x0?

Hi all,
I want to install ROM by _alexndr on a new G900F. I want to keep KNOX 0x0, so I need root to flash this ROM using flashfire.
However, the device came with android 5 when I bought it, so towelroot does not work. If I understood correctly, I have to flash stock 4.4.2 firmware (where do I get it? which tool to use for flashing? Just flash, or other things to take care of?), then I can use towelroot and flash ROM by _alexndr with flashfire. Did I miss anything important?

Get the ROM and ODIN the flashing tool from sammobile .com firmware section
Instructions under the download (Free account might be needed to download the ROM)

Can I just flash the old 4.4.2 firmware over the current 5.0 firmware, or do I have to consider something else?

I've flashed KK over LP before, and first boot didn't boot, flashed it again the same way, and it booted fine
Might need to factory reset before/after flashing if you have problems
