[Q] Stock 4.3, KNOX and rooting

Alright, where to begin.
I've owned quite a few Samsung phones by now and I've rooted every single one of them and installed custom recovery and ROMs. But with KNOX on the S4 this has made me unsure...
What will happen to my device when I root it now? I figure it'll trigger the Knox flag to 0x1. What are the drawbacks of that? Will it affect the function of my device?
And is the rooting procedure done as usual with Odin like on the S3?
And maybe most of all, is it worth rooting the S4 and installing custom ROMs?
Many questions, but I haven't found any real answers to any of them...

Nothing will happen to your device when counter z 0×1
Drawback z you'll void ur warranty & youll not get official updates if u r on I9500.If ur on I9505 then triangle away can solve both problems.No function gets hampers until you really mess with ur phone but that's after root
Yes the procedure z same
Well if ur on I9500 then there r only customised stock version nothing much only debloated or deodexed.If ur on I9505 then definitely worth it

Triangle away dont do much with the knox . Once trigger there is no way at the moment to reset this.

What happens when you actually get Knox flagged to 0x1?
You basically lose the ability to install Knox softwares, and your device will be flagged as 'insecure', which means if your company allows employees to bring their own device to work for accessing corporate emails etc and they use knox to keep security, your device will not allow this. However, you will still have the ability to use future samsung firmware releases even though you have the knox flagged.
How do you trigger Knox?
You still can root your phone with CFautoroot, but that will trigger knox to flagged to 0x1. If you try to downgrade your firmware, knox will also trigger to 0x1, therefore, once you upgrade to new bootloader, there is no way to go back to old bootloader without knox. (I would suggest if you do not want knox, but you want the new firmware, you've got to manually flash the modem.bin files using Odin)
Lastly, there is still a big question mark as to whether Samsung will actually service devices with knox 0x1

I agree with you except last words. Modem has nothing to do with knox... flashing a different modem version from rest of FW version (ROM and CSC) will probably give some data or voice problems, and he will still have the same android 4.2.2 version....
What I suggest if he wants last FW, is just flash it, root it, delete all knox files, assume he will have knox bit activated, and enjoy it.

[Q] Should I be afraid of KNOX?

Hello.
I know this might have been asked a million times already but I'm gonna ask anyway..
Should I be afriad of KNOX?
I would like to root, customize stock rom, try custom roms, flash CWM recovery & kernels etc.
but I heard and read that flashing, modifies KNOX which voids the phone's warranty but I would like to have my phone's warranty.
So should I try anything?
Is there any way to revert KNOX back to default?

KNOX doesn't carry a gun around, so no don't be afraid of it.
By rooting and doing all the things you mentioned above, you void the warranty of any phone dat has warranty on it. Samsung is only trying to protect themselves. So they don't fix more faults dat were caused by users... So, security for Samsung. And NO, it can't be reset. At least, not yet. However, there are ways to avoid tripping it. Do some research urself. I own Exynos Note 3. Cheers!

1 .Safely root using de la vega root without tripping KNOX
2. Safely custom rom using kn0x0ut Toolbox without tripping KNOX
Others will trigger knox :good:

You could get hit by a bus this week , Flash and enjoy the phone.

Thgough theres danger involved there too if you do flash....:silly::laugh:

Well, I have previously rooted my phone without tripping the knox. I didn't flash any custom recovery, firmware or kernels, though.
Now, unrelated to knox, my phone started to behave strangely (reboot loops on charging and erratic signal reception) - some device problem I guess - , and since I have not tripped the knox, I'm going to take the phone to the service centre for a replacement, hopefully free of charge, since it's been only 2 months since I bought it.
Using an International SM-N9005.

I guess if some manufacturing defects cropped up, not related to the flashing of custom firmwares and so on, within the warranty period, and if the knox is tripped, it may be troublesome to replace/repair free of charge. That's the only downside I can see by tripping the knox within the warranty period.

[Q] Upgrade to 4.4.2 and lose 3rd party accessory access?

Has anyone run across this who have upgraded to 4.4.x?
Apparently, in the version of KitKat released by Samsung, without a 3rd party chip installed in the accessory, the accessory won't be recognized by the ROM.

Will updating/flashing Framework require you to trip knox though? Meaning, does it require a different recovery? Not clear in the link you provided. Sorry, I'm not an expert at all on framework and how to get it on the devices.

Well rooting (unless you are on MJ2 firmware) will trip your KNOX I'm afraid but no custom recovery is required only root access, - but if you were rooted, then it's just a case of installing Xposed framework (pretty much just an .apk install) - then open the app, go to downloads and find that mod, hit install and reboot and that's it pretty much

rooting <> tripping Knox

Not a true statement at all that rooting will trip Knox. I used Kingo and haven't tripped Knox at all. I'm just asking if flashing Xposed framewwork requires a different recovery and bootloader which WILL trip Knox as it requires a new recovery. However, I have 0x0 root so, no, rooting does NOT imply you've tripped Knox at all.
I just looked up Xposed and was able to install and run the APK and able to install a few of the add-ons.
Nice. And all that without tripping Knox, hmm.

Well usually rooting any firmware past MJ2 trips KNOX especially if using CF Root, I cannot comment on Kingo as it was banned and still is banned on XDA afaik, so never had any dealings with it. Plus I tripped my KNOX straight away. Also, from what I have read around, after you reboot when installing certain root methods, it'll trip KNOX automatically (whether yours has/.will is a different story)

[Q] Re-enable KNOX after root (with KNOX counter 0x0 intact)

Been trying to look for an answer but all related thread seem to talk about KNOX tripped (counter 0x1)... But my case is different here.
I have rooted my S5 G900F with Towelroot without tripping KNOX. Right now the phone is running stock NG2 firmware with root and KNOX disabled (KNOX counter remain 0x0, device status Custom).
Due to work requirement, I need to encrypt my phone, but encryption won't works with KNOX disabled. My question is, is it possible to enable KNOX (while rooted), then go on with encryption and disable KNOX after the encryption. If so, how? What is the effect of having KNOX enabled while remain rooted?

Good question

This question has been asked in the CF-Root thread many times. CF recommends to keep it disabled. Otherwise, the phone will be unstable (autoreboot) and other strange things could happen. Read CF-Root thread for more details.

After some reading, it seems like you can restore KNOX by: unrooting with superSU, flashing a stock rom, and do a data factory reset.

The system status and current binaries both have to be showed as official in downloadmode to use KNOX.

I read that, but I didn't use CF-Root to obtain root (as it well trip KNOX), i used TowelRoot (without tripping KNOX). Don't know if it would behave the same as the CF-Root method.
Thanks for pointing out.

That means I have to unroot it, not exactly what i'm looking for...

AFAIK Knox (the software container) will never ever be enabled when you are rooted (even with Knox counter set to 0x0).
I believe it checks on root access.
As I understand it correctly, the company where you work for only requires that your phone is encrypted and not manageable ?
I work for one of the largest companies in the world and my phone (S3) is not allowed to be rooted.
The container software (Airwatch) checks on that.
When every check is confirmed, only then will it make a container and encrypts the data in that container.
And from administrators it can be managed, like remote wipe, anti-theft, etc

That was my understanding too!
To re-enable KNOX, reflash stock firmware as described. After that, you can try again (towel) rooting your device, and Do Not disable KNOX. Though, I read that root will not work quite correctly?
Please write back with your results if you try it!!!

You probably right that Knox won't work when phone is rooted...
Well, with My Knox available now, no full phone encryption is required (as encryption will only be within the Knox container). Maybe one fine day I'll reset my phone, root then unroot temporary in order to try My Knox...

Hey Guys,
I have a doubt on using KNOX.
Actually I don't care about tripping my Knox Counter. (0x1) but I just require to know whether I can use KNOX just like before rooting without any problems?
If Warranty is the only concern to be worried about , due to rooting of the phone; I can live with it, but does rooting limits/restricts the users from using KNOX and any/all of its functionality totally?

In my experience(for what it's worth, lol), I have seen no performance issues with Knox functionality by rooting. Flashing through Odin trips the warranty counter and voids warranty. There are apps that disable Knox but the ones I've seen warn you before doing so. Hope that helps. Good luck

You will NEVER be able to use the Knox Container EVER again after ur counter says 0x1... Samsung made it for business enterprises for security concerns, if these *Android Hackers and Modders* will just bypass the Knox security then Samsung wouldn't have business enterprises using the Knox Container because it can just easily be bypassed..

Makes sense...!!! But I see almost everyone requesting to get a root access mentioning about Warranty void. I was wondering if that is the only reason can we use knox even after making our phone warranty void. Anyways I got the idea. :sly:

I need help
please some one .. i need help and it's so important . one of my friend encrypted his data though knox and regardless of what super su and root do with knox and it's disabling knox ... he rooted his phone ! (he is todler and didn't take notice )
anyway his knox now is disabled and he can't access to his data because in security knox is disabled .. how can we enable knox so he can decrypt knox with password and access to his data ... thanks in advance and keep in mind that please guys if you are not sure about how can solve problem without losing data , guide me . data encrypted with knox is so important to him .
target device is Galaxy note 3 n9005 .

You cant use knox on rooted device
When uroot your device, ur device status nd binaries change to custom. KNOX checks that. If the binaries are custom, you cant use KNOX ever.

Is there a way to completely unroot and go back to KNOX 0x0, all official? Even if we pay Samsung service centre?

true sir, my Samsung Galaxy S7 edge unable to even install myknox after flash back to stock rom

[Help] Install 4.4.2 Custom ROM without Knox Tripping

Sorry, for question, I am coming from Nokia Lumia and HTC worlds. So, I still don't have a lot of experience regarding Knox issues. I have searched a lot and find nothing specific for my case.
My N9005 is on Android 4.3 MJ7 version, currently I have 4.4.2 OTA upgrade downloaded and ready to be installed. I want to install any rom 4.4.2 or above without tripping my knox. Already rooted using Kingo method and installed MOP.
The question is if I upgraded my device, does MOP still capable to install the custom ROM without tripping Knox, and how to backup my current nand without installing custom recovery?
I think that I can also install custom recovery via MOP without tripping the Knox, right?
Thank you very much in advance

Last I checked there wasn't a clear cut method, it could be done. And since you're still on 4.3 it may be easier.
Have a look around and check the threads, there was some workarounds posted a few months back. It's not easy but it was doable. Using Mobile Odin Pro (still possible AFAIK)
I personally like a lot of others just tripped KNOX as it was a lot easier. However this isn't a viable option for everyone.
So in my opinion and my personal advice, weigh up the pros and cons of potentially tripping KNOX.
If you wanna flash custom ROMs, kernels without any headaches. Aren't too worried about your warranty (especially if you've had your device a while and are in the EU)
CONS: while you may be able to get things flashed and not trip KNOX, you may accidentally trip it with something so trivial, you'll always be trying to not trip it by avoiding different things.
Really, and ultimately only you can decide. No one is gonna judge you if you decide it's best for you to not trip and go the workaround methods.
Either way, whatever you decide, the forum is here to help if you have any questions or get into any difficulty. Good luck in your choice.
