Had this phone for over a year, and after various random crashes decided to try replacing the stock rom (updated) too a custom rom so it don't have all the junk samsung hardwired to the device.
What I found was knox and the bootloader are LOCKED.
Knox keep track of any warranty hack attempts for example if you go into recovery mode ya see on screen in white in small print Knox warranty = 0x0. if u hacked phone unsuccessfully it will read 0x1. so if u took phone back to samsung they would refuse to fix it.
So I tried towelroot and kingroot and both failed after various searches on net found out the bootloader is locked and you cannot install a custom rom with this locked or root the device.
My question, has any of you lot found a way around this without disturbing the knox warranty value. Or how to bypass the bootloader ???

Hello,
Came from a Nexus device and I have some questions about "unlocking" etc.
When i want to install a custom kernel, do I need to unlock KNOX? What is knox?
If I unlock my phone, can i go back?
Thanks
Knox is in general a security feature. It is used for example for BYOD but it also brings a malwarescanner/antivirussoftware.
You dont have to unlock the bootloader since samsung phones come unlocked by default.
But if you install any custom software (kernel, rom) you knox flag will be triggered and this is not reversible.
Furthermore, this will disable Samsung Pay. Once KNOX is tripped, Samsung Pay is disabled forever on that particular device.
Hey guys, thanks in advance for your help.
I am not new to rooting, but I'm new to T-Mobile S6 G920T, so I had few questions.
Some info about the phone:
Knox status is 0 (not tripped)
SIM Locked to T-Mobile
Firmware: DOJC (g920tuvu3dojC)
I recently bought this phone refurbished, and I have hard time finding the answers I'm looking for in the forums (I've spent about 4+ Hrs in searching so far)
So my questions are:
1) Is there a "non-root" way to SIM unlock this phone? I tried using the "cable" method from unlockbase, but it looks like they can't implement the temp root method, and therefore it doesn't work
2) It doesn't look like there is currently a way to root the phone with this firmware without tripping KNOX, is this correct? Can I downgrade?
3) Is the bootloader of this phone unlocked? I see that there is an OEM Unlocking option, but some users are saying that this doesn't do anything on DOJC (The primary reason why I bought this model was the notion that T-Mobile has unlocked bootloader)?
4) What happens if I trip KNOX, it looks like I can still flash the original firmware, but the counter will still show 1+ instead of 0 - is this correct? Or rather - is there a fool-roof way to flash new firmware and reverting back to the old one with clean KNOX if needed?
Bonus Question) What is a good 6.0 Rom to flash in my case? Are there SIM Unlocked ones? What about CM13 - if I flash it, I lose TouchWiz along with some of the apps and possibly the FingerPrint scanner?
Thanks for your attention,
A.
hi
ad.4 Knox show +1 so You broke warranty - Im new on s6 (I will buy soon) so I don't look about it yet but I think You have to try find KNOX reset (De-Knoxer) or something like that.
Look on the threads about ROOT or Recovery - maybe into is the KNOX subject.
[EDIT]
Try it from THIS thread. Maybe works.
Sorry for my bad En.
No known way to revert Knox to 0, once it`s triped, there was a ping pong root available on 5.0.2, which didn`t trip knox, but 5.1.1 and later root methods always trip knox, and there is no successfull way of downgrading to 5.0.2 that I heard of.
When i go to download mode, I saw "Warranty Void : 1 (0x302)" or something like that (sorry, but I don't hold the phone right now) is this mean the Knox has tripped? i have tried searching on XDA, mostly just said 0x1 mean the Knox tripped, but i saw said 0x500 also mean the Knox tripped, it is just "Warranty Void: 1" need you to look when you want to know if the Knox tripped or the code (0x1, 0x302, 0x500) or the whole line "Warranty Void: 1 (0x302)".
The phone condition is on bootloop, since the owner said he never did something that should tripped the Knox, i little bit confuse. The System status also said Custom. I want to help fix his phone.
Thanks
If system status said Custom and it also says Warranty Void: 1, then yes, KNOX is tripped
Someone rooted / custom recovery'd it
lots of samsung users are looking forward that issue can figure out...
Samsung strongly attacks to who modifies samsung phones...

thanks for the info, i want to help him fix the phone, i've tried to flashed with some version of firmware but doesn't work, still bootloop, since the Knox already triggered then i'll try using custom recovery or ROM, can you show me some reference thread, since i can't enable OEM unlock and the owner said never do anything regarding system change, i have read some but enable OEM unlock is necessary for any customization.
I have read a lot about Samsung KNOX and how it is supposed to work, but the more I read the less I know how KNOX is tripped.
I understand what KNOX is, I know how it works and I know the supposed "reasons" it exists.
I also do know, that KNOX has changed a couple of times in the past years, which is perhaps the reason I find to much conflicting information on this topic.
So, since the A51 is quite a new phone, I want to know, how KNOX is tripped on the Galaxy A51.
Is unlocking the bootloader already enough?
Can you unlock the bootloader but flashing anything will make it trip?
What exactly is allowed with the newest KNOX and at which point does it exactly trip?
Can you not modify anything anymore, without tripping KNOX?
since Knox requires a separate login even after phone boots up i would guess it is not accessible with just a booted up and unlocked phone. last i read it created an additional "encrypted sandbox" on the already unlocked phone where data did not cross the sandbox barriers.

Unolocking the bootloader isn't enough to trip Knox, it trips once you flash a modified file.
Like TWRP, a ROM, etc that doesn't have Samsung's signature of official software.
Hello Everyone!
Okay, here's the thing, i wanted to root my Samsung Galaxy A51 (SM-A515F) Firmware: EUH1(KSA). I've unlocked my bootloader, then thought that i didn't want to risk bricking my phone rooting it so i stopped. But i noticed that just unlocking bootloader trips Safetynet apparently(which sucks) and it trips knox too, which i believed since I can't use security folder and Samsung pass anymore and it kept insisting that my phone is 'rooted' (which it isn't, just the bootloader unlocked). I then went into ODIN mode to verify it, and found it that my knox counter is still 0 (000000).
TL;DR, so does unlocking bootloader trip knox? cause most of the sites, threads, guides I've went to generally says it does. Thnx for answering.
