[Q] rooting without voiding warranty?

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:

@BACARDILIMON it wont even take that long!

Just need a yes or no, please..

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?
Thanks for the fast reply, too!

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.

Afraid of rooting

Hello guys. Recently i joined note 8 forums from note 3.
I have 950f with dual sim. I can choose to oem unlock. But i have galaxy care and guarantee of the phone. I want to root to add apps for camera modding and etc. So I'm afraid of rooting to change the agreenment of care and other stuff. If i root i change the agreenment?

yes

Instantly voids your warranty. I mean don't you already know that? Just saying.

If afraid of rooting, DO NOT DO IT, and about warranty, depends of your contry/carrier polocies, in Mexico rooting does not void warranty at least claiming it with the biggest carrier telcel

rooting will also void usage of Samsung Pay.

It will trip Knox and you'll lose secure folder forever too

There is no compelling reason to root today. From themes to ad blocking, there is a solid non-root solution available. The reasons to avoid root like warranty and Samsung Pay are pretty big. IMO, stay away from root. Your money tho.

Yes you can. Root and enjoy

That's bad advice since OP is worried about voiding warranty and losing functionality...read post 1.

If you have any bit of desire to maintain warranty coverage you just simply stay away from the topic of rooting. End of. Any stink of warranty stuff, rooting is a no go.

When you root, you trip the knox counter, there is no way back, even if you unroot and return fully stock. The knox counter stays tripped which means you'll lose Samsung Pay and Secure Folder forever.
You gain features and functionality with root, however. Native automatic call recording, ad-blocking (not just in the browsers), Titanium Backup, Full system Backup, AFWall+ (blocking internet access to specific apps)... etc.
So it is up to you to decide whether it is worth it or not.

Is there some secret way to hack or bypass Knox without triggering it?

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.

Hello mina,
The goal of this thread is to list all changes when you trip/void Knox.
This list is not complete, feel free to help me to keep it updated.

Mmh, I already sent a Galaxy Note 4 on Custom ROM in a PSM (Point Service Mobile, shop who sent to Samsung Repair Center) they flashed Original ROM and sent to Samsung.
They repaired the phone without ask me money.
Moreover, in France, they must repair the phone if the hardware is defective

Called "Samsung Stars" (Some dedicated team that I assume S9 and Note 9 users get access to) yesterday and in the UK at least, they confirmed that if the KNOX bit has been reset and you send the phone to be repaired, the service centre won't even touch it, hardware fault or not.

This item (warranty, )seems to have been discussed with every Samsung I can remember owning since Knox came into use.
You won't likely get a definitive answer since many owners in various countries including UK will argue that neither Samsung or any other manufacturer gets the final say on warranty repairs.
Many countries, including UK have consumer protection legislation that gives purchasers repair rights for defective items. You may get company warranty department staff and retailers who don't fully understand these consumer protection, you may have to be assertive or get trading standards department to assist you to get repair for defects.

This is definitely news to me. For folks like myself who try to maximize battery durability, this would be a very welcome side effect. Constantly keeping an eye on the battery percentage while charging is getting old

Yes in France if they sell you an hardware, you can use like you want. I even wonder if Knox restrictions are really legal to be honest.

I'm pretty sure when you trip Knox you are "burning a bit" like a fuse bit on an adrino hobby chip and that's permanent

thats only when root is obtained using combo firmware typically on locked bl devices since factory/combo firmware limits charge to 80%
