[Q] Knox removal after Kingo Root

After successfully rooting my Note 2 with Kingo and Disabling Knox with SuperSu my Knox counter still remains at Zero. My question is if I use Titanium Backup to remove all of the Knox related files now that Knox has been disabled would it still trip Knox? On a side note after removing Knox would it be possible to install a custom Kernel without tripping the counter? I've searched the forms and haven't found any answers to this question. I want to keep my counter at ZERO which is what it is at the moment

[Q] GT-N7100 rooted on Android 4.3 Knox 0x1 can't update OTA

Hi
I am using Samsung Galaxy Note II GT-N7100
I did a mistake by not doing more research before rooting my phone and now my Knox flag is 0x1.
I upgraded my phone to Android 4.3 then rooted it with Chainfire autoroot using Odin.
Now I am not able to remove KNOX bootloader also if I try to flash a KNOX free bootloader Odin show unsupported device error and device gets soft brick then I have to flash Chainfire autoroot again to start the device again.
Is there any way to get KNOX free bootloader? or to be with Knox bootloader but everything fine like it was before.
Disadvantages are
I can't use Knox feature now.
Cannot update my device OTA or through Samsung Kies so downloading form Sammobile and flashing takes a lot of time.
I don't have any other problem I am running on stock rom 4.3 but I want that I should able to update my mobile OTA and if possible able to use KNOX feature again.
Thank you
Have a nice day

So far, this issue of 0x1 back to 0x0 is still fly high in the air. I read a lot of thread regarding this issue, until I myself also a bit headache
But, from my understanding after reading so many thread... Once it tripped, there's no way to return back. And you can't (theoritically) to revert back to 4.1.2 bootloader, but perhaps, there's a way. And yes, once it tripped, you can't use any KNOX features.
I still have no better conclusion as well regarding this issue. I got read 1 time somebody is able to revert back to 4.1.2, but still with KNOX 0x1. Most are failed. You may want to read all the thread regarding this issue with a search.
I'm here not to answer exactly on how to revert back. But just to share what I know regarding this tripping issue. To be frank... I also want to know about this, as I need to root my MJ7 Note 3, which so far... no solution yet for the tripping KNOX, so I still hold on to it.

YOu can root if you have not trip 0x1 without tripping it.

I also want to know about this said:
I found a way today on the internet that If Note 2 is at 0x0 flag you can root it without increasing the count but it will show custom that you can revert back to original by triangle away may be there is a way for Note 3 too.
I have already rooted so problem starts here

but in Software update you device is modified. May it is showing you because you have already the latest update. Please can you tell me the Device status in Downloading mode also please report back if you are able or not to download update OTA when available.
Thank you.

Same boat
My phone is in the same boat as you. My desire was not so much KNOX as to have 4.3 with phone encryption and root. In order to succeed with my desire, I have to leave the stock 4.3 recovery intact. This greatly reduces my root options. I had root before the update, but it was unable to update after going to 4.3. I tried Kingo in an attempt to fix root, but to no avail. I decided to unroot and re-root. I used Kingo to unroot. From there I had to run saferoot a few times before it was finally able to install SuperSU and associated files. The version it installed is the latest so I'll have to wait until the next release to find out if it can update. Everything else seems to work fine except ES File Explorer appears to no longer be able to mount the /system RW.
saferoot can be found over here

[Q] Successfully Rooted with Towelroot on Note 3(SM-N900T), have some questions...

Successfully rooted without tripping Knox with Towelroot. NE6 firmware. I have T-Mobile Jump and would like to Jump to the Note 4 when it comes out. If I install TWRP and make a backup of stock, will I trip knox and void my JUMP eligibility? Wanted to install via Flashify and install Xposed framework at some point down the line.
Thanks!

As long as you didn't flash a custom kernel or recovery, it should be OK once you flash stock.
Even if you trip Knox, flash back to stock and jump when the time comes. They generally don't care about that as long as your phone is not damaged.
Knox warranty void is not the phone warranty. It's telling you Knox can't secure your phone anymore. Its (Knox's) warranty is void. People all over the Internet don't even know what Knox is and they spread misinformation.
Look up what Knox really is. It is an app that runs on your phone and creates a secure Android environment within itself. It's like another phone with its own launcher and app store that is secure. It's meant for employees to use their personal phone for work purposes as well.
When you trip the Knox warranty, Knox triggers an efuse that will prevent the secure container from being able to be created... Meaning Knox will never work again on your phone. It's a security measure so that companies will take the Samsung phones seriously in the work space. In reality it has worked for them as the department of defense recently approved a few Samsung models with Knox.
If you don't plan on using Knox for anything, then trip Knox and enjoy custom kernels/recoveries etc. If you do plan on using it, it's not a good idea to even root your phone as the whole purpose of Knox is to be secure and rooting will make Knox vulnerable.. You might even get fired if your IT department finds out.

Makes sense and I probably will flash a custom recovery. I just don't understand the fuss with people wanting not to trip knox if they're not even gonna use it.

I successfully rooted my Tmo Note 3 with Towelroot v2. I am currently on NE6 Boot-loader and have Knox at 0x0 and would like to remain there. I would like to upgrade to the new firmware NF1 which is not rootable with Towelroot yet. Does anyone know if using Mobile Odin Pro is able to keep root if manually done without breaking/tripping Knox? I think I remember reading somewhere that it was okay to do so and ignore the message even though it asks to download a file and then it gives a warning saying that:
"Using, Mobile Odin on this device will void your warranty, as the Knox counter will be triggered .This is not reversible".
Can someone confirm if its Okay to ignore the warning and that activating Mobile Odin Pro on my phone is OK without triggering Know 0x1, or was that other posting I read somewhere wrong? I cannot remember where I read it. If not possible to use Mobile Odin without triggering Knox 0x1,. is there any other way to root NF1 without triggering knox on our device? What do you guys think?

un-answered question............
I don't know why I have not asked this before, but here it goes..........
First, I just want to say that I could care less about Knox...
(my phone already has the knox pox)
But for future reference if I had a brand new Note 3 with official stock NB4 baseband
and I rooted it successfully using Towelroot (or root de la vaga) would it be possible
to simply rename a custom rom like Hyperdrive to "update.zip" and copy it to the
internal sdcard then boot into the stock NB4 recovery and flash/install "update.zip"?
If the only problem with this method would be the fact that a different kernel would
also flashed along with the rom it would be an easy fix by just removing the kernel
from the custom rom file before flashing the update.zip?
I know that more likely than not this method would not work.
But if it did work it should not trip the knox right?

I just checked and it's OK to "install" Mobile Odin on your phone and it
it will NOT trip the KNOX counter by simply installing it as long as you:
1: Don't flash any custom recoveries like twrp/cwm.
2: Don't flash any stock or custom kernels.
3: Don't flash any modems/baseband or bootloaders.
4: Don't flash any custom odin flashable firmwares.
In mobile odin there is no option to flash cwm/twrp
flashable zip files of any kind including custom roms.
Good luck!

Why would flashing a stock kernel/baseband or firmware cause Knox to change to 0x1 when done through Mobile Odin? I thought this would happen only through custom based ones?

First of all I never said not to odin flash stock official firmware in my post.
If you or anyone else knows for sure that the modem/baseband or kernel you are
wanting to flash are 100% official stock 4.4.2 Kitkat NB4/NE6/NF1 versions then
its just fine to flash those.
However since knox cannot be rolled back and to keep things on the SAFE side I
always suggest the very safest way to do these things which even a NOOB would
understand without getting into trouble with a lot of unexpected issues. :laugh:
Good luck!

How to Downgrade for warranty

So how do I downgrade my phone so I don't have knox. My screen cracked and need it to take it for repairs. I had a co-worker tell me just crush it with a semi. They won't check it and you will get a replacement. Thankz

If you already have a bootloader with Knox, you can't downgrade.
MDL was the last bootloader without Knox. MK2, NB4 and NH7 all have Knox. You can download the free Samsung Phone Info app from the Play Store and it will tell which you have. Or, if you go into download mode and there is any line that says Knox, you have a bootloader with Knox. You can only re-flash the same version or newer, but the Knox flag won't go away. If it is tripped, it will stay tripped.
There have been reports that sometimes Samsung will check the Knox flag, but T-Mobile doesn't usually. YMMV.

[Q/A] Answers Added - OTA's/Updates, rooting & tripping Knox? - other questions

So I rooted using chainfires method for my Tab S 8.4 wifi (T700) and it tripped Knox (0x1). I know there is no way to currently reset it and there is a bounty out for it. No big deal on tripping it, I wanted to root anyways and want to try out CM12 eventually. After doing some research it appears Knox gets tripped when unofficial firmware or recoveries get flashed via Odin. Knox is not tripped when you flash official Samsung firmware. I had a few questions though I can't seem to get a clear answer on and was hoping to find some or get a discussion going at least about Knox for the Tab S.
Questions and Answers
- Are you still able to receive OTA updates on a stock rooted rom/recovery with Knox tripped?
A: No, not while rooted, "Operating System on your device has been modified in an unauthorized way. Try downloading software updates using Samsung Kies on your PC" Unsure if Knox prevents it but most likely does not.
- Will you lose root if you can get OTA updates?
A: No OTA Updates allowed on rooted devices. Reports have stated that flashing the official firmware update via odin will unroot the device but maintain data, most likely kies is the same when updating. However if a bootloop occurs after flashing, you may need to wipe data and cache via stock recovery.
- If knox is tripped (0x1), if I flash a custom recovery (TWRP/CWM) or use chainfires method to root again will it trip Knox again (0x2)?
A: YES & NO, Knox will not read (0x2) if unofficial img's are flashed via Odin but reports on other devices have stated it will read {0x1(2)}
- If yes can you trip Knox too many times, rendering device inoperable or bricked?
A: NO, tripping Knox only informs if warranty has been voided by flashing unofficial firmware/recovery/img files and root kernals via Odin. When the knox warranty void status is tripped, the knox software will no longer work.
- What is tripped specifically in Knox (for the Galaxy Tab S), an efuse, or is it software or binary code?
A: Most likely an eFuse. There is no way to reset the flag counter as it is believed to be an eFuse that once gets blown it stays damaged and cannot be reset.
***New Questions***
- Will flashing a custom recovery img (TWRP/CWM) via ADB trip Knox (0x1)?
A: Yes, it will trip Knox.
Thanks to all who answer and contribute.
If there are any new questions, updates to be added or wrong information to be corrected please let me know.

No OTAs when you are rooted on custom rom. Dont worry, someone will make a stock custom rom to flash with twrp Or you can odin flash stock lollipop and root with twrp
If you do the ota it will probably not install because of root.
If you flash a custom recovery, or root again.. Knox will stay 0x1. It wont change.
Knox is like a check when booting up your device. Its more like uhh protection. If you install custom stuff then you dont get protection. Knox was a security feature that samsung included. Its really not needed as it really doesnt work. Thats why people trip it. I highly doubt its used for security but I think its just used to detect if warranty has been void or not. Its not something that you should worry.
Hope this helps!

Thanks, I figured Knox is nothing more than just a feature to let Tech's know if the warranty had been voided. Also I figure that flashing the updates myself when they come out would be the best option. Thanks again.

how do you make the knoxx counter back to zero ??

Read post two above yours. It can not be reset to zero once it's tripped.

Even if you root and trip knox, although you cannot receive official ota's, you can still use samsung kies to still recieve the updates.

updated OP with answers to questions.

Stupid Knox. This is one "feature" of Samsung devices which makes me less likely to purchase them in the future.

For the new question, flashing any custom recovery with odin or adb will trip knox. Flashing stock should not trip
