Hi all.
I'm asking this question because a friend of mine told me that he knows someone who could crack and unlock pretty much any phone's anything, for a price.
Just the other day, my friend took back his phone from another person (why he took it back is another story) who had been using that phone of his. So obviously before my friend could use it he'd need to factory-reset it. But at the last step the phone asked him for the email password of the previous user, the person he took the phone back from. Instead of contacting that person, he sent his phone to the... well, hacker. Then the next day he went to take it back and it was unlocked already! He paid about 40 dollars for it.
How?!
He also told me the hacker could even crack or bypass iPhone X's lock screen, but that would cost about 500 dollars. For Note 8's lock screen, he said he could do it with his eyes closed.
So what is all this?? Is all this possible?
And Knox? Is there really some way to crack Knox?
Please enlighten me. Thank you.
About knox, there is no way to reset it once tripped, because it is a fuse, (an e-fuse), I know
that cracking the lock screen can be done, but it involves resetting the phone
The topic question is about NOT tripping Knox while cracking it. Whether there is such a way, or tool. Because I was told by someone that someone else could do it.
Cracking the lock screen can be done but involves resetting phone? Reset how?
Love stories when it's pertaining to someone knew someone that could or did something. My neighbors friends daughters step dad's uncle Ron, reckons he can hack any phone including bypassing Knox.

I'm not saying I believe it. That's why I'm asking here. I wouldn't have if I believed. At least explain how he cracked the FRP.
So I'm taking your response as "no, Knox can't be hacked".
Next person.
Knox is made as it is for this exactly purpose, you can get through it, yes, but leaves the trace 0x1, which means someone tampered with it, so the owner(individuals or corporations) can know for sure it has been compromised, and take the adecuate meassures about it, as for unlocking a device without the propper passwords or biometrics, that is something that can be done, but nobody even knowing how-to do it, will teach you how to do it here, as it could provide a way for potentially illegal practices, and try not to be so adammant in yor post
Lol and I'm not even asking to be taught how to do it. I'm only asking to know whether there is or isn't such a way (or ways). That would already be satisfying. Because right now something that I trust a lot (Knox) is, apparently, crackable. I of course wouldn't believe what I was told so easily, and so I'm here.
What I'm saying is that I understand pretty well how Knox works, and I know what I'm looking for. I'm just here requesting input from anyone who might know a bit about this topic, and I thank anyone who responds.
Well, you got the answer, no, there is no way to crack it without showing 0x1, that's it
Yes, I want to believe "no" as well. And that's what I'd believe for now. I also personally do not think it's possible. But considering it was coming from someone who cracked the FRP....... That was what made me to make the effort to start this thread.
OP, you've raised a few different issues here...password unlocking and Knox...
Knox can't be reversed once tripped, period. Fuse-based or something similar to that anyways, no way to undo that.
Breaking lockscreen passwords in another matter entirely...I'm sure you could Google that but I don't think it's appropriate for discussion here.

I understand tripped Knox can't be reversed. I know. And if a hack attempt trips it, then the hack has failed. But my question here is whether it's at all possible (even theoretically) to crack Knox without tripping it.
Yes. Lockscreen can be bypassed or broken. But what about FRP? My friend's phone's FRP has just been broken. Hmm...
Discussions about knox have been around in xda for years, no, there is no way around it, never have been, I doubt there will ever be, as it would render samsung pay as not trustworthy, that is why tje e-fuse is a physical security flag

Ok I understand now... Anything is possible in theory I suppose, but if anyone ever cracked enterprise-grade security like Knox it would essentially render it useless for all (because it could no longer be considered secure). Samsung has millions of dollars, if not more, riding on preventing exactly that. No one has cracked it yet, and it has only become more secure over time...so I doubt they ever will.

Thanks. The ways both of you put it make lots of sense. I'm regaining my confidence. After all, Knox is something that has gained the approval of many governments and organizations around the world and is declared fit for government work.
Then again, I learned that the Snapdragon Note 8 could be rooted without tripping Knox right? (Is this still the case?) Does this mean anything in terms of Knox security? (Mine is an Exynos by the way, and AFAIK Exynos Note 8 doesn't have this issue.)
Lastly, well... this concern isn't exclusive to Knox because any security system may have yet-to-be-discovered potential exploitable flaws, but Knox also has its share of flaws in the past, such as http://www.wired.co.uk/article/samsung-knox-security-vulnerabilities. I guess we can't really do anything about this individually.

Most of the Note 8 Snapdragon variants have a locked bootloader, so the root method is different there and do not affect Knox as far as I know. Other differences though, like not being able to charge past 80%, etc. Exynos bootloaders are not locked and use the standard root methods.
Hello all i think i have managed to turn off the samsung secure boot. i can write to the recovery without blowing the bootloader fuse i tried write the s8 snapdragon twrp to my recovery in past always just getting secure boot fuse blown resulting in having to odin

back to samfail v3. Somehow this time all i get is a screen saying please take phone to att authorized retailer we knoticed you have unauthorized software on recovery. I reboot phone boots back into the pre rooted stock rom samfail v3. My knox is not tripped i also can do full back up and restore on flashfire pro no problems all partitions i was to afraid do bootloader partitions but can all the other protected ones modem efs ect. Am i losing my mind or is something going on here i have the full backups 6 gig worth saved so if so maybe someone more qualified can look at it.
Cash that i odin it back samfail v3 if only that easy
Just throwing in my 2 cents...
I believe there is a hack whereby the kernel is replaced when rooted. This will show that KNOX Warranty void is 0x0...
In reality KNOX has been triggered and Samsung pay won't work but the bootloader screen does say that KNOX hasn't been tampered with. Flashing a stock rom with ODIIN will reveal this trick however...

What I meant was if rooting could be done undetected by Knox, essentially does that mean Knox has... failed?

One of Knox's primary jobs is to monitor and protect the kernel, no?
I guess if in reality Knox has still been tripped then Knox has done its job...
No I have a Knox checker it says Knox is valid and see linux is in permissive. I'm on a att n950U but my stock recovery is for a n950X but I can load it and be rooted . I assume all v3 samfails are same.

not sure if it's too early to ask this yet, but is there already a root method that doesn't trip knox or whatever thing that can void the warranty?

Short answer, no.
We all know t mobile don't check for root so why bother yourself with this
g3 soon to be NOTE 4
its all these IBone converts that are flocking to this phone..
They're so used to Apple telling them what they can and can not do, that they dont yet know how to handle the freedom of Android/T-Mobile..
i'm just going to assume you're directing that at someone else. i've been using using android for quite some time. there was no knox when i rooted my phone before.
i don't buy insurance from tmobile so they won't be the one that's handling my warranty issues if something happens.
Like the OP, I refuse to waste money on Carrier insurance, and my previous phones did not have Knox. So it remains an important issue if you are relying on Samsung warranty. It's clear that existing root will trip Knox. My question is - what is the chance that there will be a root that does not trip knox in the future. Is it worth waiting or is knox considered to be bulletproof?
Edit: and no, I never owned an iPhone, and all my Androids have been rooted so far.
From what I read nobody has been able to break the Knox that Samsung share this knowledge with Google.
If the phone died and no fault of your own, Samsung will not take it back even if Knox is tripped?
Im not expert but I think that Samsung has to have a way to remove " tripped Knox flag " or any phone with hardware failure and Knox flag tripped would have no resale value if, for example, usb port is replaced.

it IS too early to ask; the phone has been out for a few days, so if you're paranoid about rooting because of tripping Knox, you'll have to just wait around and see, or develop an exploit and share it with the rest of the folks who feel they need it..
I've given back a Note 2 and a Note 3, KNOX wasn't out for Note 2 but it was rooted. Note 3 had a counter of like 12, as stated above, T-Mobile doesn't check.

This couldn't be any more true. I've rooted every phone I've had with them that could be rooted and never once had them turn me down for an exchange or replacement unit. Hell I think I replaced my old one s maybe seven or eight times over the years I had it and I even stopped flashing it back to stock and just sent it back. Not like it's super hard for them to clean it all back up to stock.
I'm certain that when you return a phone to most vendors, they just throw it into the "defect" pile, and those phones either gets wiped and re-imaged, or they send them to some 3rd party who buys them cheap and does that on their own.
after spending many years as a director of sales for a consumer electronics company, I know how expensive it is to try and inspect/repair returns, so I cant imagine that Samsung/t mobile/att and who ever else even bothers to look at them.
If you think about the thousands of phones coming back as returns every day, handling them any more than absolutely necessary is a major losing proposition for these companies, and they only care about profit. When you return your rooted/knoxed/bricked phone, they NEVER repair it, you just get a new or rebuilt one sent out to you.
But hey, if you want to worry about tripping Knox or sending in a rooted phone, and that you will be in trouble/charged/punished for that, then you just go ahead and keep thinking that!:cyclops::cyclops:

Looking forward to going back into rooting my phone again with the Note 4 so far being such a delight out the box. For screen recording & tethering with no T-Mo oversight I also wanted to know if there was anything to be aware of as far as any popular apps or even default apps that shuts down when it notices that root is active or Knox counter is tripped.
Also curious if any rooting methods is out there that either avoids tripping the Knox counter or if Knox counter can otherwise be changed somehow.

We have Knox on this phone.
NOTE 4
Why are we so hard on people even though they sometimes ask question that we think are noob type question.
To answer the question and I can only speak for myself is that there are no down sides to rooting...at least for me. The only down side I see is tripping Knox, but most of us that are on xda could care less about Knox tripping. I won't buy a phone that can't be rooted.
Just my opinion!!

True.. Been in the game since the G1 days but would never be a dickhead towards people. Maybe it's just me but I haven't rooted my N4 yet but I sure you will trip up Knox. Even though they (developers) always find a solution to most problems
I think he is aware Knox is on this phone being he asked if there is a way of avoiding tripping Knox.

Towelroot on the Tmobile S5 didnt trip Knox but if you plan on flashing a custom recovery or insecure kernel then plan on tripping it . My advice is that if you have Handset protection is not to worry about tripping Knox . Nothing Voids handset protection even throwing your phone at the wall . It does Void the manufacturer warranty though but 99% of the time Tmobile handles it and replaces your phone . I have been using Tmobile for years and had to exchange devices and never had a problem "even when the sales rep was aware of the warranty being tripped" exchanging devices . they just said they reflash them and use as replacement devices .

True True.. They say use the search button and now since this thread was created someone will use a search button and have this thread in their results . Usually people that post things like that have had the same thing said to them before . Its like the jerks leading the jerks. On the other hand we do have a lot of useless threads building up in the Note 4 section . Its Like Bloat for XDA
Huge consequences. Guilty conscience, bricked phone in purgatory, and samsung frowning at the very root attempt.
I know ive heard that knox is here to stay on the note 4 forums but the galaxy s6 has root without tripping knox i just wanted to start a discussion on this matter and ask the simple question....
If it can be done on s6 why not note 4 ....
Now ive already tripped knox and probably dont care if i ever have a clean knox but i know there's plenty of people who would love to root but cant because they need knox... I just dont see how it can be as cut and dry as the note 4 forums have portrayed. It can be done obviously so is it a lack of necessity becuase so many have already tripped knox that they just arent interested in working it out or what.
I kno its been talked about before but not that ive seen has it ever been rationalized that the s6 has it why not us
why does knox even matter? most of the CS reps dont check KNOX and it isn't required other than for business purposes.
Well thats exactly where it does matter to the rest of us its absolutely pointless we don't care..but I've seen at least a few threads of users asking about it. So it has to matter to some users. And hell usualky just the thrill of the chase is reason enough to modify something to suit our needs after all isnt that why we all root and mod our phones , becuse we can..
And ultimately just interested in why it hasnt been done yet. Seeing it usually done on most other phones.. Plain curiosity i guess. Because it doesn't matter to me i would never utilize anything knox offers
Note 4 is not S5 or S6. Its different with a lot of scripting things. Not sure about this whole "chase" thing you mention. A lot of us here aren't into being criminals or feeling a thrill out of it, just wanting to modify our phones and have freedom to do so. Has nothing to do with being able to get away with it, etc. Retaining KNOX would be nice, but I don't think that's why a majority of the users are trying to do it
I have no idea where your taking things but way out in keft field obviously
I know exactly why we all mod our phones ive been here for quite a long time i never said anything remotely close to anything' criminal and am annoyed at someone implying i was. And as are all mankinds endeavors these are a challenge we rise to becuase we can thats what i meant. You really should be sure of the lines your reading in between before implying things
I was merely interested to know why its not been done in the note which is the most business savvy of all the galaxy line and you would think since knox is a corporate or business feature for the most part tthe business oriented phone would be the one to do it to
Michael Scott would be disappointed in you
My note 4 has a tripped knox, the GPS seems to be defective and since I'm not with the t mobile, I can't take it to the mobile for warranty. Samsung wouldn't take it, Or would they? Anyone have experience?

Simple answer: The Galaxy S6 had a kernel exploit, the Note 4 did not. You cannot just will an exploit into existence, you either find one, or you don't.
Also, for wanting or needing knox intact on your phone for business needs or whatever, you will want to be aware that rooted S6 users with intact knox will have to stay on 5.0.1 forever, or until a new exploit is found. I am sure any smart businesses incorporating knox would ask you to kindly update your S6, saying bye bye to your root.
T-Mobile don't care about knox being tripped.
I just want a quick answer as I keep finding people claiming to be able to root t-mobile s6 sm-g920t ver. 5.1.1. I cannot find anything to support this without a lot of headaches, much less being able to find and download needed files for root.
Can I successfully root this Samsung Galaxy s6 SM-G920t?
Or should I go back to my HTC phone?
Thanks,

FYI: I got this phone yesterday as a promotional and did not have to pay for it. I have always strayed away from Samsung because of all the hassles involved in rooting any Samsung device over the course of the last 10 years or maybe a little less. As soon as I signed in to my Google account the damned phone automatically updated. "Thanks for the options Samsung!!! I didn't have any choice but to go through with the update.
Yes, you can root it easily but you will void your warranty by tripping Knox.

I am not worried about warranties. I root all of my android devices. I pay the phone companies a lot of money every month. I usually buy all my devices straight out too. So Samsung can do what they need to, as long as they stay out of my way, I will stay out of their way. Anyway, my other main concern is all the calling problems and the finger print phone lock. Will these break regardless?

The only downside to rooting the latest firmware versions is you cannot use Samsung Pay with Knox tripped. Other than that, I haven't experienced calling problems or any issues with the fingerprint reader. Haven't heard of call problems as a result of rooting but the fingerprint sensor not working was a result of using the engineering bootloader (to maintain Knox warranty status) on a previous firmware release.

Welcome to XDA
There's that pesky little efuse that protects Knox's integrity... once blown the mobo or that chipset needs to be replaced.
Sammy will do it for $400 apparently, according to one member here who did what you're thinking of doing. Get to know it a bit first...

No, rooting the S21 ultra is not possible without tripping Knox and voiding warranty.
You could root it , use it for a year or two and then trade it in. I've traded in four so far with no issues.

One member recently had their display die and Samsung did replace it but charged them for a new mobo because of the blown efuse.
Samsung is pretty much silently admitting there's a display issue on some of these units.
If the 3rd party firmware fried the display he lucked out because the display was from a known bad batch. Samsung can only determine this many times by direct inspection, not remotely.
Samsung usually doesn't do warranty repairs on rooted phones, right?
Interesting, isn't it? It doesn't give you a warm cozy feeling though about Samsung though

The problem being the phone was rooted. Better have deep pockets if you want to root a new flagship Samsung device.
Basically Samsung returned it to factory specs and charged to repair the "damage" caused by rooting.

Knox services and factory warranty aren't the only casualties when you root a Galaxy device. Also it depends on how you root a device, that's assuming your device can even be BL unlocked. Many users end up with a very expensive paper weight as bricking the phone isn't uncommon. You'll lose Secure Folder, Samsung Pay, Health. OTA Updates can be restored if you flash the original FW via Odin. A number of apps can also be made unusable after root. I would weight these considerations beforehand as there are a number of apps which will customize your device without tripping the BL.

The potential to brick the phone should weigh heavily in one's decision to root especially on a expensive flagship device.
Just read all the " Help!!! I bricked my device" threads posted here. Lots of pretty paperweights...
Losing the factory warranty on the display and mobo are a big deal. Both are expensive and hard to repair.
OTA updates break phones too
It's the first apk I package block.
Those other apks I never use but each person is different and if your needs change... you don't want to find yourself painted in a corner with paint that never dries.
The stock Samsungs can generally be configured to run very well without rooting. More than one way to skin this cat...

There's that pesky little efuse that protects Knox's integrity... once blown the mobo or that chipset needs to be replaced.
Sammy will do it for $400 apparently, according to one member here who did what you're thinking of doing. Get to know it a bit first...

Hi. Welcome to XDA.
No, rooting the S21 ultra is not possible without tripping Knox and voiding warranty.

Thanks for your welcoming, I have my phone through a carrier. If I succeed and root and then decide to unroot can I still lose that warranty even though I want be going to Samsung to fix it ?

You could root it , use it for a year or two and then trade it in. I've traded in four so far with no issues.

I have my phone through a carrier and it's on upgrade and protect which is whenever a new one comes out I get to replace it with the existing credit.

Knox services and factory warranty aren't the only casualties when you root a Galaxy device. Also it depends on how you root a device, that's assuming your device can even be BL unlocked. Many users end up with a very expensive paper weight as bricking the phone isn't uncommon. You'll lose Secure Folder, Samsung Pay, Health. OTA Updates can be restored if you flash the original FW via Odin. A number of apps can also be made unusable after root. I would weight these considerations beforehand as there are a number of apps which will customize your device without tripping the BL.

Thank you for your long answe as it had so many new information to me.
I don't usually use any of these apps because I replace most of them with Google pay and anthid fitness apps, while on the other hand for apps services like find my mobile and secure folder.. there are many alternatives .
I'll wait to see what the S22 Ultra will bring to see if I should root my phone.
Thank again, really appreciate your answer

You're out of luck then because you can't revert knox. I just did it through Samsung credit and they don't seem to care but the warranty is still void either way if it's rooted.

Doesn't matter if you unroot later. Once you root and trip the Knox flag, it is irreversible. It's not a software flag, it's a hardware flag called an e-fuse. Once blown, it stays blown. Whatever you do with the phone after that to restore back to stock, it will stay voided. Knox related stuff will never work again unless you change your motherboard.
I think it is possible
Could you elaborate please?

All the elaboration you need has already been said. If you want more assurance that this is not possible do a search for reset knox and see for yourself. This is just one thread of many and it was started in 2013... not trying to be a jerk but this horse is dead.
