[Galaxy S 4 General] tetakpatak:
There was much easier way:

You should have totally hard-bricked it by flashing a wrong firmware (like one for i9300 or similar) or just a bootloader. It would be totally dead and they would replace MB within the guarantee without any chance to check what happened.

Yes in the Netherlands. I have rooted my Note 3 with Towelroot and installed a custom rom with a stock kernel and thus keeping knox cool.

But here in the Netherlands different guidelines apply. You can install your software and it does not matter if your knox trips. If your phone for instance freezes with a custom rom and you can prove it also does this when you install stock then the shop owner (thats right NOT Samsung) must fix it.

This is seen as normal use here.

So if I want a different kernel I will just trip knox. They (the store (!)) will have to fix this under warranty.

XDA is a site for development.

It is not a place to teach users how to deliberately destroy their devices for the purposes of claiming a warranty.

That is fraud

What's downside when is knox became 0x1??

People claimed can not be OTA on the future update and some of BYoD network provider will not allow to it. And also company do not allow their employee to used a knox voided device? Is that could be?
[Galaxy S 4 General] Tlailaxu:
You got a 70 to 30 chance that your warranty will get denied if you send the phone in for repair and you can`t use the KNOX app (which would get your phone banned from the company you work at,IF they use/enforce KNOX encryption)
[Galaxy S 4 General] nashmarkt:
Yes on my SGH-M919 I am no longer able to get OTA from T-Mobile. I am on 4.4.2 and can not get 4.4.4. That part sucks a bit.

I like to install a clean 4.4.4 or Lollipop rom but I have not found a clean 4.4.4 ROM that is without some issues and still no Lollipop Rom for my phone.

What does this mean? I know abt 0×1 but mine is only '1'

I can still use my warranty?? Help...
[Galaxy S 4 General] mrstabs:
No you can't. That means Knox is tripped and warranty is now void. You'll have to pay for any repairs.
[Galaxy S 4 General] s3nr1:
This sucks :( The rooting threads should have a great big red banner on top. I used CF Auto root, now I got 0x1. I did not install any custom recovery...just flashed cf auto root...

How about custom ROMs? Are we screwed here as well? Considering customs ROMs need custom recovery to flash, the future is not that bleak?
[Galaxy S 4 General] nashmarkt:
Can't agree more. There should be a major red banner warning users. This is not a minor issue. It disables the phone update function.

You should really know that know matter what you do to your phone/system is always at you own risk. I am not being a jerk here, just saying that I rooted my s4 and broke the Knox counter.... I had no one to blame but myself.
[Galaxy S 4 General] nashmarkt:
Noone is blaming anyone here. I broke my knox counter and I am not blaming anyone BUT if I had known that there is a possibility of that and that it would stop my phone from receiving OTA updates, I would have never rooted to begin with. You can argue that all this information was somewhere in the 1000+ messages in the thread and I would argue with you that it should be posted right at the top of the thread for everyone to know. We are all trying to help each other out (some more than others) to minimize the risk of having a bricked phone or a phone that no longer can receive OTA updates, right? Just saying that not all the risks of rooting not clear when I started on this thread.

Hi All,

I was trying to update my S3 LTE with OTA updates to a more recent Android version without success. I now know why :crying: even if I have no clue what operation exactly "broke the knox warranty".

I may have to learn to install a new ROM (and to make a backup before!) to use a more recent Android version on my phone.

de-knox

are there still hopes for de-knox 0x1 to 0x0? in google i/o it was told that samsung has handed over its source to Google for knox to work on selinux security. with Google sources open, is there a chance that it can be reverse engineered?
[Galaxy S 4 General] Tlailaxu:
wouldn´t count on it
[Galaxy S 4 General] crzr:
That's what I recommend to you people do some research before doing anything to your phones, I saw in almost all threads about rooting that it wil trip the knox counter, and it's all at your own risk

Personally, I was too worried about that in the beginning, but later I realized rooting is more important than a 0x0 flag or free repair warranty
[Galaxy S 4 General] nashmarkt:
I installed CM ROM and Clean Kitkat ROM and saw no improvement in my Phone performance. All I saw was less features on my phone, a more simplistic UI (which i did not like), so I reverted back to my stock ROM. Now I can to longer update my phone. Hence the post about having the warning larger displayed on the first page of the site.
[Galaxy S 4 General] s3nr1:
The way I was reading the information is that, flashing custom recovery or kernel will trip knox. Apparantly that what samsung said as well, cf-auto root probably flashed a modified kernel and thus tripping knox. As there is no way to root without tripping KNOX with this method, there should be a warning.

Anyway, I'm not blaming anyone but Samsung. I have a warranty with FS will probably microwave the phone when it's time to change, the next one won't be Samsung probably but they're the only one that has REMOVABLE BATTERY and MEMORY CARD.

0xfffffc reset back to 0x1

Just wanted to add some experience recently gained flashing ODIN images.

My SPH-L720 got Knox Warranty Void and Knox Kernel Loc 0xfffffc after downgrading modem firmware (I've heard downgrading the TZ file will do it.) This meant that I could not boot TWRP!

Eventually, flashing the complete NG2 Odin file (including bootloader) put my Knox Kernel Lock status at 0x0, and my Knox Warranty Void Status at 0x1! IDK what exactly did it, but I'm happy to say that I can now boot TWRP 2.8.3.0! :D

Cheers!

As I know it is impossible to revert a tripped knox on an i9500 ...

But Today I switched to Note Edge, and I will hand over S4 i9500 to one of my family members so I just flashed I9500UBUGNJ1_I9500UUBGNJ1_I9500UBUGNJ1_HOME.tar.md5 via odin..

And what i see now on the download mode is Knox Warranty Void : 0

I have rooted and installed unlimited number of custom roms. Is it really what I am thinking? My knox counter really reset itself?

If yes, how is it possible?

For qualcomm editions it is still impossible reset knox counter I think. As i9505 has qualcomm chipset it is impossible to reset knox. For i9500 (exynos) there are a way to reset knox but it is to difficult because you had to have jtag. So we have to wait till there are a way to reset the knox flag. Qualcomm sux :D ahah

[Galaxy S 4 General] zvieratko:
I know I'm a bit late to help you, but under EU law you will NOT lose the warranty just because some e-fuse is tripped.

In order for the warranty to be void, the issue you want fixed would have to be caused by you, and the party that needs to prove that it is so is the vendor.

Taken to the extreme:

If you disassemble the phone, take the system board and replace an audio jack yourself using soldering iron, and then your memory chip goes bad, it is still under warranty, unless you actually broke it or caused it to break by your repair.

There's no way for any vendor (based in EU) to get around this.

That does not mean that service centre can fix the issue you have (because they really could be forbidden by Samsung from touching the phone), in which case it is up to the vendor to either fix it himself (in whatever way) or replace/refund. If this becomes common it will be a huge problem to all vendors, because while you are protected by consumer laws, they are not, and if they agreed that warranty is void for devices with KNOX tripped in their contract with distributor, then they take a huge risk by selling such a device.

IANAL, but I believe that if you had the phone fixed in the meantime then you are eligible for compensation from the vendor.
[Galaxy S 4 General] informatec:
There's that EU regulation (1999/44/CE) that is generally interpreted so that rooting/flashing may not break hardware warranty.

But warranty needs to be provided by the seller, not by the manufacturer!

I have tried that with Samsung already and they just let me know that I have to deal it with the seller.

So I sent my phone to the vendor and get the same result: No warrenty because of flashing ...

I can go to a lawyer and try to sue, but who wants to complain Samsung or a big distributor?

I change to One Plus One and hope it will work longer ...
[Galaxy S 4 General] subscope:
My board died like in November. I sent to samsung assistance and said to me that it has knox flag with 1 and they won't repair and gave to me a price to apply a new board. They wanted 210eur to replace board. Well I bought a s4 with broken lcd and take off the board to my s4. And I have a new phone now with knox flag 0 :) and I just spent 100eur :p samsung and knox just sux :)
[Galaxy S 4 General] zvieratko:
Yes, vendor is the one responsible.

I don't know what customer rights organizations are present in the UK and how they work, but I know that there are orgs here (Czech Republic) that I can go to with the necessary proof (phone, warranty protocols etc.) and they send a legal notice to the vendor for me, and if he refuses they even have their own lawyers - I'm pretty sure something like that must exists in the UK as well. And AFAIK you have a pretty well working small claims court?

Or... you can try Slashdot or some larger UK technology news website - stuff like this makes a good story.

Personally, I have a legal insurance for this kind of stuff, and it works very well - it costs you nothing but a few minutes to file it with the insurance company and they take care of the rest.

Is it possible with jtag and emmc replace?
[Galaxy S 4 General] stugib:
Just wanted to share my Knox experience.

I've just got to the end of the line disputing this with Samsung. I have a 20 month old S4 which got itself into a reset loop, which I've now hopefully traced back to a battery failure.

I've no interest in rooting. Have never tried it. Don't want it because I need online banking apps/corporate Exchange access. But I tried to fix the reset loop myself by getting into recovery mode. Took me a fair few attempts because of the battery problem, and one time I managed to get to 'download mode' by pressing volume down instead of volume up, asking me if I wanted to install a custom OS. Didn't go any further, gave up and sent it back to Samsung. Got it back by return of post with a helpful picture of the screen with the 'Knox 0x1' included. I've explained all the above to Samsung but as far as they're concerned their software is flawless and couldn't possibly have incorrectly reported this, and the custom OS screen I saw is impossible without me downloading an app to it first.

Luckily I think I've now done a factory reset and a new battery is on the way, but the flag is now tripped and probably now not going to get any more updates and will be screwed on any hardware problems now.

Could that have been enough to trip the flag? I honestly haven't installed anything else - Play store and Amazon Appstore is as exciting as my phone gets! The only other explanation is the supplier flashed a grey import when I bought it, but they'll never admit that even if they did.
[Galaxy S 4 General] nikosdd:
Go and ask the store you bought it,you never know :) it's impossible to trip knox without flashing custom recovery, rom etc. Before going in to service, Knox apps worked correctly?
[Galaxy S 4 General] stugib:
TBH I never really paid them much attention. I vaguely remember registering the 'lost my mobile' thing which I think relies on Knox? Thinking about it, I have had OTA Android updates since owning it so can't have been the store.

Apart from getting to that screen once i had a couple of failed attempts to clear cache and data in the recovery mode. That's the only plausible explanation I can come up with :(
[Galaxy S 4 General] tetakpatak:
[MENTION=5324471]stugib[/MENTION] it is totally impossible that your knox flag is tripped only for seeing the warning screen of the download mode.

Someone had flashed something on your phone at some point.... Maybe even the guys in Samsung service did it, to void costs

[Galaxy S 4 General] Exroid:
Just a thought knox is a type of kernel or boot img correct? if so cant we decompile it and disable write protection and remove or flash over the knox bootloader. for instance if u decompile to boot.img and make it insecure which will start root when u type adb shell
[Galaxy S 4 General] FlanjeUK:
You can root without tripping knox, depending how you root. Flashing a custom ROM, Kernel or Recovery WILL trip it, you can also trip knox by trying to downgrade the bootloader via Odin.
[Galaxy S 4 General] Exroid:
Im not trying to root with knox, i can do that 10,000 different ways. Im trying to come up with solutions to Samsung users knox problem. because right know i can updrage or downgrade with knox bootloader just have to remove the bootloader from the .tar package and recompile it then flash with odin. i want full control over my device i dont care if i trip the counter or whatever, just being able to downgrade the bootloader is what a lot of people want
[Galaxy S 4 General] stugib:
Certainly not done any of those. Still only the original + OTA upgrades.

So what do you make of Samsung's 'mobile specialists' response that :

"they have advised that in order for the handset to be in a position to accept a customer operating system then a facility (such as an App) must first be downloaded into the device to enable this because intrinsically our handsets have nothing built in to accommodate this.

Therefore, based on the unequivocal evidence supplied by the Service Centre the conclusion can only be that during your attempts to resolve the issues that rooting was undertaken on the handset."
[Galaxy S 4 General] tetakpatak:
[MENTION=5324471]stugib[/MENTION] either the service has tripped your Knox, or someone else has flashed a custom kernel or recovery on your phone- maybe before you owned it. Some people claim that normal flashing of a stock firmware with Odin has tripped the knox.

I don't like this Samsung's "virginizing" the phones with Knox. I never had unrooted phone, yet all my phones got old and remained technically 100% fine.

well thats another option...but i think knox is just a hidden bootloader and the efuse is just a fail safe...which mean when you bypass that hidden bootloader(e.g remove and replace it with the one with a 0x0 flag) it will blow the efuse...but the only way to know it is to trace the whole boot process....
[Galaxy S 4 General] marcelogabriel:
If KNOX involves an efuse, a part of software on the kernel or bootloader should be involved on read and display the 0x0 or 0x1 status in the ODIN screen.

It is a matter of time that this check will be discovered and bypassed on custom kernels and/or bootloader.

That's means that a sort of shell could be used/included into the kernel to mask the ODIN screen, for example...

Only a thought...
