It is impossible. Could not recover knox if you root

I was actually wondering about this too. My knox counter is there, but it's greyed out and is on 0 despite the flash counter being at 11. Will I be able to unroot at all?
Thanks.

Hello sir, I think you can unroot your device by flashing the stock rom again, just make sure to make a back up all of your apps as believe that it will wipe your data if you're coming from a rooted device, just download the stock 4.3 firmware from sammobile

n7100 upgrade to 4.4

Hello
I was wondering if someone can help.
I have a u.k n7100 running 4.3, its is rooted with knox disabled, in doing so I have tripped the knox warranty counter
I want to upgrade 4.4.2 stock
Is this possible due to the fact of my current situation. Will the upgrade go through?, like a routine upgrade keeping my data. I assume knox will be disabled and i will lose root, which i am fine with. Please let me know if it can be done and it is routine stock flash procedure using odin.
or are other steps required.
thanks

You can update with no problem at all, using ODIN you will lose data as for root it depends on ROM you flash if stock with root then you keep root but if not then lose it, Id recommend flashing a custom ROM with no wipe

AFAIK Mobile ODIN flashes stock ROM without the bootloader, someone correct me if I'm wrong.

Ofcourse you can upgrade to any stock firmware via odin but once KNOX is triggered it cannot be reset so even thought your binary counter will be reset after flashing official stock ROM, knox will still read 0x1.Good luck.

How to have custom recovery

Hey guys its been a week since i bought the note 2 and i rooted it. But i cannot find how to flash a custom recovery tutorial anywhere. I am on jellybean 4.1 and the rest of the details (firmware etc) can be found on the screenshots attached..
I would highly appreciate if someone can send me a link to the guide for flashing.. thanks a lot in advance

Just simply flash via Odin
You can choose CWM, Philz touch or TWRP

You got two options either root your phone while being on 4.1.2 or upgrade to official Indian 4.4.2 and then root it.Ofcourse once you root your current 4.1.2 you can try custom 4.4 ROM and if you don't like it you can go back to 4.1.2 or flash a 4.3 custom ROM. To root your 4.1.2 rom read this guide.If you decide to upgrade to 4.4.2 Indian firmware download it from here.
To flash the 4.4.2 ROM on your phone download it from the above link(there are 3 links where the ROM is uploaded) ,use any of the links and download the zip file,extract it you'll get a tar file,put your phone into download mode ,open odin v3.09 on pc and flash the official stock rom by checking the AP tab on odin.You can find tutorials on youtube on how to use odin to flash official stock firmware so just look them up if you need it.Once you flash stock ROM you can root your phone via this guide.
Okay so now things to remember.If you root your 4.1.2 ROM and want to try 4.3 or 4.4 custom ROM you need to flash MJ5 bootloader in order to have working wifi.Bootloader is flashed directly on your mother board and it cannot be downgraded only be upgraded.MJ5 is the last 4.3 bootloader which is KNOX free(what is knox ,blah blah,you can read about it on google).Advantage of MJ5 is you can try 4.1.2/4.3/4.4.2 rom and your warranty and knox remain intact but if you upgrade to official 4.3 or 4.4.2 ROM you'll be on knoxed bootlooader which means you cannot downgrade to 4.1.2 anymore plus rooting a phone with knoxed bootloader will trigger knox 0x1 and your warranty if any will be void (no way yet to reset Knox).So if you have warranty on your phone then my advise is root your 4.1.2 Rom,download any 4.3 or 4.4.2 custom ROM,you wont have wifi working then flash the MJ5 bootloader from here and read this post on how to flash bootloader.
I know it's a lot of info to you but your best guide is self reading from the above links i hooked you up with.Also read comments from people cause that's how I learned I read and read a lot before i jumped the rooting bandwagon cause wanted to make sure i don't brick my phone. Ofcourse whenever in doubt STOP RIGHT THERE and ask us.Dont attempt things that you are not sure of.Good luck.

Thanks for the help

Wow that's a lot of info you provided there, thanks. I am not new to rooting as far it goes I have rooted and flashed many roms on my galaxy s advance and my micromax A87 before that. But note 2 was a flagship device so there are many complications that come along which got me confused. As for now, I have my rooted 4.1.2 stock rom along with cwm recovery flashed via rom manager. I am planning to flash either DN3 or the Xperia Z-ized rom. So my question is: do I have to flash mj5 bootloader to flash DN3 and xperia z-ized or can I directly flash it from cwm (with factory reset and necessary wipes of course)?
BTW, I have heard that knox is a security application that prohibits rooting on samsung phones. It also had a reward for $18k for those who can bypass the knox on the S5 and root it. If I am right, then I think I am fairly acquainted to knox.
Once again, thanks a lot for helping! Appreciate it

Since you are on stock 4.1.2 MJ5 is required for wifi to work.i learned 2 weeks ago that even mj5 is not required as previously thought by us at least not while flashing 4.4.2 TW rom.When you flash 4.4.2 custom ROM you wont have wifi working,then flash custom kernel like agni or nadia and wifi works flawlessly so one doesn't need to flash mj5 bootloader.I am not sure if this would work on 4.3 ROM you could try xperia z'd 4.3 custom ROM then flash a compatible 4.3 custom kernel and see if wifi works if it does you're set.This was new to most of us so I asked the person who told me about this how did he manage to do this and he told me apparently custom kernels have some sort of wifi drivers on them so when we flash custom kernels on 4.4.2 ROM wifi works but it wont work on stock kernel unless you upgrade to MJ5 and on stock kernel.MJ5 is safe to flash anyways since its knox free bootloader.
Actually 4.3 and 4.4.2 note 2 phones and others got knox on them but we found a way to disable knox after rooting our phone SuperSu disables it but knox is triggered to 0x1 and there's no way to reset KNOX since it's concerned with the motherboard of the phone which is the heart and soul of out note 2.So that bounty you might be talking about how to reset it perhaps.Even if they succeed in reversing it doesn't necessarily mean it would work on note 3 or note 2 cause of the phones being of different hardware .i don't know the technicalities of this.

Lurking around in xda and reading as much as I can and participating in discussions related to Knox.I was clueless to all this Knox and how it works.My previous phone was HTC HD2 so samsung note II was the first serious smartphone I owned so just wanted to be extra careful that I don't end up bricking my device so read and read and asked questions.

Going back to stock.

I've been waiting for months for an official samsung kitkat update for my phone. (i9195L). Today I checked on sammobile and saw that the update has arrived, for Trinidad and Tobago.
Now that it has been released, I want to know if I can flash it over my Carbon Rom, which has Android 4.4.4.
I want to know if I can go back to stock and flash this new firmware with kitkat on my device via Odin, or if I will have any problem considering I'm actually downgrading to 4.4.2.
Thanks in advance.

Good rule of thumb with OTAs. Don't perform then on a custom rom. I would use Odin to report to stock. Then see if you can get the update via OTA. However keep in mind that the newer update may not have a root method so if that is important to you, check into that. And always back up in recovery! Flashing back to stock should not harm you device.

U won`t really downgrade But take into consideration this :
Do u have Knox bootloader active ? 0x0 or 0x1 in download mode ? Once u flash KitKat u can`t downgrade to samsung jellybean. U can flash aosp again if stock samsung won`t fit u . If u don`t have Knox bootloader i woyld flash an older firmware that does not contain Knox, 2 3 times in a row until u bring your phone to Official not custom and after that flash samsung kitkat. That way u will sure have knox not triggered, all flashed good modem and so and no problems. I think i write too much and u won`t understand a thing ( i`m bad at explaining stuff )

Yes, you write too much, lol. But I get your point. Thanks for the reply.
I have Knox set to 0x1 so I guess it's activated, but I don't have any plan going back to jelly bean. i will stay with kitkat.
Besides I think there's already a way to root stock with kitkat via Towel root, so I guess it's a lot of help.

Towelroot works only on roms made before july i think. Older won`t work

I don't completely agree. Towelroot worked on stock 4.4.2 for me fresh after an Odin restore. I believe it doesnt work on HTC phones and something else. Don't hold me to that I could be wrong. But Towelroot should work great for the OP

I'm currently on DU Rom, if I want to test offical Kitkat I have to flash it with odin? And if I want to go back to DU how can I do it? With a backup?

Yes if you stock kit kat without root and such you will need to use odin. Using odin will give you a complete stock. Recovery, kernel, etc. Meaning you won't have a custom recovery to restore a back up. Back up your current setup using your custom recovery and keep the back up on your external storage. If you choose to go back if stock doesn't work for you, you may be able to restore the back up once you re-root and install the custom recovery, but it may cause some errors. I'm not 100% sure that the restore will work or not. My suggestion is to find a stock rom that is only rooted and not modded. Less hassle that way. And much easier to go back to your current rom if you don't want the stock rom.

One question: If I already installed this firmware (kitkat) How can I root it? Towelroot? I don't want to trigger Knox, I want to Root it workout having to enable Knox and put that message with yellow letters..
Edit: I rooted it by installing recovery and flashing the rootkit. So far so good.

Note 3 Rooting

I have a Note 3 and im trying to figure out the process of rooting without tripping the Knox Counter. I rooted my Note 2, years ago and has been awhile. Also like to know is there a "triangle away" method to reset the counter.
Model: SM-900T
Android: 5.0
Baseband: N900TUVUFOL1
Kernel: 3.4.0-6005498
Knox: 2.3
Thanks in advance

As far as I know, there is no way to root without tripping Knox.
If the phone is not under warranty, tripping knox should not be an issue. I have tripped Knox on a few phones and have never had an issue.

I asked the same question a while back, and only just 2 days ago rooted my SM-N900T knox 0x0. Asked: Here.
To achieve root on the note 3 without tripping knox you must downgrade from the Lollipop firmware OB6, or FOL1 to NE6 using PC Odin.
Once downgraded to NE6 download and use TowelRoot. This will unlock root without tripping knox, NE6 was the last vulnerable firmware for towelroot on the t-mobile note 3.
Make sure you are flashing official t-mobile firmwares only for kitkat/lollipop when using PC odin.
Flashing any custom recovery, kernal, rom, bootloader, or no longer supported android version (4.3 jellybean) will trip knox.
You can use sammobile to get official firmwares, or if you're risky there are likely download mirrors scattered through the internet.
Once you're rooted on kitkat NE6, to get back to Lollipop and keep root you'll need Mobile Odin Pro to flash FOL1 with the latest Super SU Zip v2.46. (instructions first page of this thread: Here.)
Rooting seems to require some gonads and research first.
When using PC Odin I left options default (Auto Reboot and F. Reset Time).
When using Mobile Odin Pro (or maybe flashfire) make sure to uncheck EverRoot!
Flashfire is the newer free mobile odin pro I think. You might be able to use it in place of Mobile Odin Pro and instead of the supersu zip in addition to flashing FOL1 it comes with an option to inject SuperSU.
I recommend sticking with mobile odin pro for confirmed results. MOP does not support Lollipop.
Note that once you're rooted and upgrade to Lollipop your android system status will change from normal to custom. This prevents future OTA updates.
Root survives factory reset, but flashing official firmware with pc odin will make your phone genuine again as long as you didn't trip knox.
Downgrading to kitkat will very likely require a factory restore. Possibly also when upgrading back to Lollipop.
Note that the XPosed framework on lollipop and samsung touchwiz stock roms does not seem supported.
It seems some people have flashed a Deodexed rom and unofficial xposed to have it working. I made a single attempt and was unable to have it working.
I assume you could stay on kitkat and manage to get xposed working easy.
If you decide to use xposed, do not try to flash the framework without mobile odin pro, or flashfire.
Using a custom recovery, or flashing anything custom with PC Odin will trip knox.
Look over the information around to get a comfortable understanding and good luck!
Proceed only with the understanding that you could always on accident trip knox, or brick your phone.
I believe there is no known way to reset knox flag to 0 on the SM-N900T.
For future readers using a newer firmware than FOL1 it may no longer be possible to pc odin downgrade to kitkat without tripping knox.

So there is no way of downgrading without tripping knox

You can downgrade to kitkat NE6 using PC odin from t-mobile lollipop firmware OB6/OL1. (OL1 being the latest lollipop firmware, OB6 a version older). Once on kitkat NE6 firmware u can use towelroot to gain root and you will not trip knox. Unless you manage to check an option somewhere during this process that would cause you to trip knox. .
As stated, I achieved downgrading/rooting without tripping knox just a couple days ago from the current latest t-mobile galaxy note 3 (SM-N900T) firmware FOL1.
I then upgraded back from KitKat NE6 to Lollipop FOL1 using mobile odin pro.
You can probably downgrade to any 4.4 kitkat firmware, NOT 4.3 jellybean, just fine without tripping knox if you have a kitkat, or lollipop firmware up to FOL1.

I'll try it later, I also want to know if custom roms are possible

From what I've read you can install a custom rom as long as it has a stock kernel, otherwise you trip knox. You would need to flash with flashfire, or mobile odin pro though...
I've only used the stock firmware on my note 3 so don't completely know about using a custom rom.

I don't think a custom ROM can be flash via Odin. A custom ROM requires a custom recovery and a custom recovery will trip Knox on a stock KK or LP AFAIK.

Ohh ok. This is all sorta new to me as well. I had just assumed mobile odin pro could because FlashFire is its "successor".
