[Q] How to HARD BRICK Samsung Galaxy S4? - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

Long story short... I tripped Knox warranty bit to 0x1. Now I am needing to take phone in warranty, but with Knox 0x1 showing I can't. My idea: HARD BRICK the phone in a way it won't show this Knox warranty bit. Anybody knows of a way to blow away the partitions/bootloader/anything that will make the phone not turn on? I know I could do this on HTC, but not sure about Samsung devices.
Thanks!

Thanks for posting this. I had no idea this Knox thing even existed until now. I was seriously considering loading some custom ROMs after recently rooting my SG4 but now that looks like a potentially very bad idea.

odin can brick your phone. flash some bad **** to it

You guys know this is fraud. Your purposely fu**ing your device because you voided knox. Welcome to the world of rooting where you void all warranties. You knew what you were in for. So if you want to return your device for whatever reason. Be a man and pay up.

Probably the main reason behind not to decide yet to buy it. For me is a BIG ISSUE. I have always rooted my phone, and have installed many ROMS, for me, is a MUST. I am buying a hardware not a software.
95% of mobile device owners don't even know what a bootloader is and could care less. Almost 100% of companies with BYOD policies don't let rooted and unlocked phones on their networks whether or not they have Knox.
You're also confusing Knox for consumers and Knox for business. On the consumer side activating Knox is totally optional and when left unactivated makes the N3 just like all Samsung's previous devices. There are real benefits of Knox to people that don't care about bootloaders being locked. You can prevent the phone from being wiped if it's lost and stolen and can hide sensitive files you don't want people to see in a seperate container on your phone.
Here's the overview of how Knox works for consumers...
https://www.samsungknox.com/knox-consumer
For XDA Knox stands to bring with it some real negatives. Including a new warranty status method that can't be reset. So the 5% of people that want to unlock their bootloader and flash non-stock s/w without affecting their warranty have a right to be pissed about Knox. But the 95% that don't care and corporate IT departments with BYOD will be thrilled with it.

In the end, if we are talking only about the loss of the guarantee, it is a fair fee for changing the characteristics of the instrument. After all, no one is saying that the manufacturer refuses to fully service the smartphone - for your money every whim. It's time to learn how to make decisions and to take responsibility ...
Finding about this issue has just knocked the N3 from the top of my upgrade choices. Not happy at all.
Looks almost like a kicked up refreshed version of hboot on HTC devices. Anybody else get that feel?

You guys are mis-understanding what Samsung Knox is.
I'll let Apple explain it

We'll see about that. Judging from what I've read on the S4 forum, it looks like you're buying a device without a warranty.

Or to paraphrase the Google search page, are you feeling lucky?

Well, why not? I see. This is what will make the device according to the personal. At once and for all ...
Rooting voids the warranty. Anyone in there position wouldn't care about the 5% who void their warranty then try to get around it and still have it covered.
So it's harder to scam a company into covering it under warranty? Oh well... we all full well now we are voiding our warranty every time we root.

The Samsung has no obligation to xda. And we have a choice - to lose warranty or shake for it. The validity of that to pay for everything. And the phrase "I do buy the hardware and not a soft" - fundamental error ..

Yes and no. Pretty much all of Samsung's devices have had some form of flash counter in them. Plenty of people who root their devices and don't use Triangle Away have returned the phone for service, and Samsung fixed it anyway. I recall one guy saying has flash counter on his Note 2 was over 100 and they still fixed it without blinking an eye.
The legal side is questionable too - Samsung can put any clauses they want in their warranty agreement, but even if you were to agree to them in writing they wouldn't necessarily be enforceable. I don't know if anyone has ever had reason to test it, but if they refused service on my device I'd be expecting them to be able to justify with reasonable certainty that the fault was caused (at least indirectly) by running non-standard software on the device. I suspect if this were tested in court they would have a hard time enforcing it. In reality the non-rooting clause cannot render the device void of all warranty, but if the software needs to be reinstalled by them because of a faulty flash or to rectify a problem caused by rooting, they can still charge you for that.
Same way Dell can't void the warranty on my laptop if I load Linux on it........
* This is based on the terms of statutory warranty in the country of purchase. So in some jurisdictions the vendor has more freedom to add limitations.
So it's going to be impossible/hard to root this phone with the KNOX security? Is it going to be totally impossible to do it?
I am totally addicted to ROOTING my phone and installing Custom ROMs s this is going to be a deal breaker for me if it's not possible.

You do not understand the basic. This technology Samsung KNOX ® has one goal - to tie the device to one particular user. That is, the device will not be a secondary market, as the user can not be removed. This means that the whole story is not vulnerable device, basically ...
p.s. I think that's why this technology has been approved by the Ministry of Defense USA. Or maybe I just being paranoid ...
In the EU rooting does not void warranty. I work at an official samsung cervice centre and we must fix softbricked phones at no cost since the updated licence.

Knox Problem

Guys,
Just a simple question. If my Knox is 0x1, meaning if its void, what's the worst thing that can happen?
I understand that it might cause my device to lose warranty. But other than that?
Thanks!

Loss of warranty, can't encrypt your device, KNOX container won't work. But you don't need KNOX stuff if you don't use it for business.
Was expecting a ton of sarcastic stupid answers from the newbies I see nowadays.

Thanks Mate. You've been quite helpful and prompt.
This clears the confusion I had with Knox.
No my business doesn't need an enterprise security solution.
Never encrypted any of my Phones.
Knox Container is a sandbox if i'm not mistaken, No need on the galaxy. My PC has one.
Lets pop that cherry then!
Cheers!

Even with loss of warranty, If something goes wrong, Samsung will fix it, I think there is some wide confusion as to whether KNOX 0x1 = the KNOX warranty = void
or
KNOX 0x1 = Phone warranty void.
Samsung haven't actually cleared this up to my knowledge. Besides you'll see many people have had their phones fixed even with 0x1! Me personally I tripped mine without giving a second thought.

[Q] unchangable flash counter

hi guys
so i got my note 3 at the start of this month and since this is my first foray into android space i rooted it a week later, but hen i was reading online that samsung have some sort of flash counter in the phone that cannot be reset hence voiding warranty, my phone has a two years manufacturers warranty so that's not something that im looking forward to, i want to keep my warranty and not flash any roms till im well into the android scene.
im thinking of unrooting my phone just in case [havent really foudn a big enough reason to keep it rooted]
i check with triangle away that the counter is still zero but my status is custom
wanna change that back to official so will i be back in warranty territory after un rooting?
thanks

You mean knox. . As of right now. . It's changed to 0x1 meaning your warranty is void. Also threes no way yet (or ever) of changing that back.
You can check by booting into download mode by pressing power key, vol down(I think) and home key.
In top corner you will see knox warranty counter. If it's 0x0 you have Warranty. If it is 0x1 you don't.
Hope this helps

Wow dude seriously you should have done alot of research. There are quite a few threads opened about this and if you did not know about Knox before rooting then you should have never rooted in the first place.

Root Solution without tripping knox counter

Will there be a root solution without tripping the knox counter and how soon do you think after launch??
The phone isn't even being sold yet. Nobody can answer that question until the phone is in our hands.
although what EP says is 100% accurate, maybe worth checking out if something was found on Note 2 (which is no), Note 3, S4, or S5. If none on those, then most likely not on the Note 4 either.
Don't know.. Don't care lol. Not sure why everyone worries so much about Knox..as long as we can root,install recovery and flash what we want its all good. And if you concerned about warranty I would say your on the wrong site . I tripped my note 3 knox counter right after I bought the device and never looked back.

I think that in regards to warranty, Sammy still has an obligation to repair your device. They may charge you for the repair, but I'd say they'd need to prove that rooting was the cause of your problem - say a defective battery or non-functioning sim slot. :laugh:

Well, because not tripping knox is better than tripping knox I would say. What if something goes wrong with your phone that has nothing to do with rooting? I am sure Samsung in that case would also say, sorry, you rooted your phone, there will be charge for fixing this. If I create an unrecoverable brick, then, I would take responsibility for that, however, No one I am sure would want to be responsible for a problem with their phone that had nothing to do with rooting. It was just a question, that's all. I am rooting whether knox is tripped or not.
when you root your phone, Samsung says your warranty ends.
Period.
Your carrier may cut you some slack on a issue that comes up, not related to rooting, but most of them will refuse to do anything warranty wise if you are rooted. Obviously, they have to either ask you, or check themselves.
Over the years, I never had a warranty refused because of being rooted, and when I brought a phone in with a problem, I never volunteered that the phone was rooted, and they never asked me.
But, that might not be the case for you or anyone else.
Sure, if you can root, and not trip Knox, and there is a way to unroot and return your phone to stock in case of service being needed, that is the ideal scenario, but once I root any phone, I always assume my warranty is over, and I think most of us that have been on XDA for awhile would agree with that statement.

How long is the Samsung KNOX warranty period?

I have been reading that rooting will trip the KNOX, thus voiding the warranty on Samsung devices. How long is the Samsung KNOX warranty period?
Not understanding the question. You have a warranty period, usually 1 year. If you trip the knox bit in that 1 year, then warranty is up. If you do it outside of the 1 year, it doesn't matter, as there is no warranty left. Make sense?

The knox bit is a part of the hardware. When you do something (root, unlock bootloader), the bit is flipped and burnt. It can't be undone. There may be a 'counter', I've never seen one. But all it would do is count how many times you've booted the device with an non-warranty kernel. Even if you find a way to set it to zero, I don't think there's any way you can change the burnt bit in the hardware.
There's a util on play store called 'knox status samsung' https://play.google.com/store/apps/details?id=com.bryancandi.knoxcheck
As it says also, once the knox bit is set, that's it, there's no going back.
