This isn't quite entirely true. With the warranty bit tripped you cannot odin to another firmaware even if it is from Samsung. I have tried to odin back to Samsung 4.1.2 and upon rebbot it gets stuck in a boot loop. I have tried it three times with Samsung's official firmware. I have tried to odin a custom ROM and that did the same thing, boot loop. However you can odin 4.3 official firmaware, which is where I went wrong as DocHoliday77 has a ROM that is Odin free and avoids this problem, I should have just stuck with that. But you can still odin custom recoveries. I am waiting to see if you can oding Official 4.4.

So yes the 'Warranty Biit 1', as it shows up on my SGSIII and not 'Knox Waranty Bit' doesn't lock the bootloader and you can still install custom ROM's they just have to be flashed. Yes you can still install custom recoveries. The only thing I have seen is that this boot loader will not be over written by older firmware, via odin. So it becomes a issue of importance. As for me, my SGSIII is past it's manufaturer warranty so the bit being tripped doesn't even matter to me. I just don't want it tripped because I don't like the way it looks, but that is just personal to me.

However I do believe that if there is a hardware malfunction, that should be covered under warranty regardless of any software cahnges. The only software chnge that I can think of that could cause a hardware malfuntion is overclocking and thermal monitoring of the CPU or any ohter chip that relies on frequency to control everything, this shouldn't be confused with timing chips that rely on a trigger bit. (This is why CPU's can be over clocked because manufaturers run the chips at a clock speed that won't stress a CPU thus have to worry about replacement. -- just my theory) Other than that I have never seen a software written in such a way that it would cause a piece of hardware to no longer work.

If this is the case then they should offer the option to unlock my bootloader.

If they void the warranty, let me have control.

---------- Post added at 11:26 AM ---------- Previous post was at 11:20 AM ----------

it is easy to brick a phone with a "locked" bootloader.

If the bootloader is not locked it is virtually impossible to brick the phone.

KNOX is an enterprise solution to security. It is used to verify bootloader and firmware.

by locking the bootloader, they have guaranteed that individuals will brick the phone.

Has Samsung done something wrong? Absolutely.

They have installed a piece of software on my phone that limits my use. If I am out of warranty, how does this help me?

I own my phone and I should be able to install any OS that I want on it.

---------- Post added at 11:55 AM ---------- Previous post was at 11:26 AM ----------

You miss one important point, it's not the same story.

Samsung, with KNOX = 0x1; won't unlock the bootloader.

So they void my warranty in an attempted flash and won't give me control of my device.

Google does the simple thing; unlocking the bootloader wipes the device.

You can re-lock the bootloader if you wish.

Now your assertion that an OC can harm a device.

Yes if you OC for sustained periods, you might shorten the CPU life from 5 years to 2 years due to electro-migration issues.

If it gets too hot, the thermal governors will kick in and slow the device down.

If you overclock to high, it just will lock up and crash.

What does an OC have to do with the screen, headphone jack, buttons, etc. ?

Here in the US I can upgrade the firmware in my car ECU, but that does not void my warranty on electrical, and engine components not affected. Also they need to prove that my modification either caused the failure directly or was a contributing factor.
[Galaxy S 4 General] metalchef:
I just got my wife's s3 back from repair today (took 3 weeks!). It hard-bricked itself after a battery-pull (it was frozen. I pulled battery. and it died).

it was running "stock" (de-bloated/de-odexed) 4.1.2 -- but was rooted.

the service depot fixed it, no charge.

(it even had custom recovery ^_^)

I know from past experience, that if you hard-brick because of AOSP/AOKP flashing, that you have to pay (been there, done that....twice).
[Galaxy S 4 General] leolysenko:
How do they know you have a custom rom/kernel/recovery or root if your phone is hard bricked???! Your MB is replaced directly? No?
[Galaxy S 4 General] metalchef:
I can't confirm this, but it would seem it has to do with the state of the device after the hard-brick occurs. The hard-brick (my s3) I experienced prior to this, occurred during a flash of CM10.1. When I sent the device in, I was told the repair wasn't covered due to the firmware (it was fixed, at a cost of $90 -- yeah, I know: too much $$)... so I'm guessing the board on my s3 wasn't completely cooked. Plus, I assume that the repair centre's would use a jtag riff-box or something similar to test the device (correct me if you know otherwise ^_^). That said, the device came back (today), fully repaired (the PBA ("motherboard") was replaced). This leads me to believe there are variations of "hard bricks".

The device was indeed rooted and running TWRP recovery.

(I know this isn't an s3 thread, btw -- sorry for hijacking :p -- just meant to confirm that some hard-bricks get fixed, and some don't; and that ...well, I guess I may have been misinformed about what warranty covers -- but I have hard-bricked 5 samsung devices in 3 years...)
[Galaxy S 4 General] kalestew:
What exactly is a jtag riff box?
[Galaxy S 4 General] lyriquidperfection:
Its a device that connects to the phones main board via various test points to flash things at low level without download mode etc.
[Galaxy S 4 General] szczeslaw:
The only thing you cannot do with KNOX bootloaders is to flash previous versions of BL. Otherwise you can do pretty much everything without the need to unlock or modify anything. So i wouldn't call that a locked BL. Locked BL is what Sony and HTC use - you cannot flash anything other than stock, unless you unlock it first i.e. by using a website.

See what i wrote above.

Since we are (probably) talking about software governors in the kernel, do not forget that you can alter those.

Besides there were some cases of phones bricked due to OC. So one thing is theory, but another thing is practice.

Nothing. And like i've said - i don't like it either.

But at the same time i'm defending Samsung here, because everyone keeps telling how bad they are, where in reality EVERY manufacturer does that. Samsung is not the first and not the last to limit warranty. Many people here want to buy Sony or HTC, because of what Samsung did. But i think, that in their anger, they forget that those companies do EXACTLY the same. Or even a bit worse.

Warranty terms vary from country to country and from manufacturer to manufacturer. In many cases it is regulated by the local law.

In EU you can now use unathorised service centre. But you still cannot tune your engine or producer can void your warranty. But few years back it was a nightmare. My friend had a 4-5 years old car. Most of the manufacturers give you 10-12 years of anti-corrosion warranty. His car got rusty, so he went to get it fixed under warranty. And they refused, because he exchanged oil once in non authorised service centre. Does it make any sense? No. But again - tough luck. Should we start flaming GM now (it was an Opel)? No. Because EVERY manufacturer does it. You can say "i will never buy Samsung (or Opel or whatever) again, because they limit my warranty". No problem - move to something different. And than you will discover, that the other company also has the same rules for warranty.

Soon you'll be out of choice. So will you ultimately stop buying anything?
[Galaxy S 4 General] L4ky:
Hi all, i own two i9505 brand Vodafone ( Italy )

I still have a old version of 4.2.2 because i don't want knox in my device.

I would like to install custom rom in both my Galaxy S4 but i'll stay with official rom ( just with root ) until a solution to Knox will be found and working.

I've got some ideas, please don't insult me! I'm a C++ programmer and i know something in electronics so..

1) We have a boot loader which insert Knox in our device. If we replace writing directly to the memory ( i think via JTAG or something similar ) the part of the boot loader with an older one, we should have knox installed but not working cause the old bootloader doesn't know what knox is.

Could this be a solution ? I know it would be for a very little amount of people.. but this could be a step!

2) As i read somewhere in the net, the Knox counter is an hex value that can only be increased right? So, if we know we can increase it, why don't increase it until reaching overflow? Then the counter will be back to 0x0 and when the system check the value he doesn't know there is an overflow state.

Please tell me if this ideas can be useful, especially the second one which i consider better.
[Galaxy S 4 General] kalestew:
That is possible with jtag but hardly anyone has access to that.

And I believe, but don't quote me for this I would need to check on this but there is another security feature associated with the hex value?
[Galaxy S 4 General] frostmore:
this is what i had in mind as well.insead of trying to crack knox,why not jus remove it altogether??!

all we need to know is where is knox installed,downgrande the firmware before knox and be done with it.

i think its much easier to remove knox than crack it.samsung did not spend millions researching knox jus so we can crack it with a few thousand dollars worth of equipment.

---------- Post added at 05:13 PM ---------- Previous post was at 04:52 PM ----------

@szczeslaw whatever reason u have for defending samsung,that is pretty much fine and well.

thing here is samsung forced knox on private consumers like us and deny us hardware warranty jus because we want root?

whats more i cannot even downgrade a official software if i wanted to...so since when did samsung become the master of me,telling me how to use MY fone which i paid for with MY money??

samsung are doing what htc did by locking boot loaders and adding binary counters,the difference here is htc gave developers a choice to voluntarily void their warranty so they can unlock the bootloaders,thus giving them officially rightful full control and access to their fones.

samsung is not doing that and is doing an apple bullcrap...which is why ppl are not happy abt it.

seriously,sometimes i think samsung is jus jealous ppl are installing cm or bloatware free roms in their fones,getting better and longer life out of their fones than they would like...who actually like TW roms when clearly cm is a much superior rom.

again i say,its about choice,i do not want knox in my fone,remove it! thank you very much!
[Galaxy S 4 General] szczeslaw:
I just like Samsung phones. That's it.

They are not telling you anything, maybe except that you cannot downgrade bootloader. And since they want KNOX to be secure, it's a right way to go.

You still can root, flash CM or do whatever, that doesn't require downgrading BL. And yes - you loose warranty. Again - AS WITH ANY OTHER PHONE of like HTC, Sony or LG.

I like TW roms. That's actually a main reason why i buy Samsung. Hardware-wise i could go for anything else. Yeah - i would miss AMOLED, but anything else is fine. It's just that i like those features added by Samsung, that are not present in other phones. I don't think i'm the only one that likes stuff like "smart stay" and thinks it's usefull.
[Galaxy S 4 General] toeshot:
I actually preffer a TW over a CM. I remmber CM in the beginning with the G1, of Course before that was JesusFreak (Had to Give Props). The CM ROM's back then were good, But the hardware was crappy, hence we needed ROM's that could give better performance and to SAVE space by moving apps to sd and sys files to sd. As time moves on hardware gets better. Now we have quad core processors 2GB of RAM 16GB, 32,GB, 64GB SD cards, some of these phones are more powerful than some peoples home computers. Nothing against CM but as hardware has improved a custom ROM isn't necessary for most users, however if I want a custom ROM I want the size to be smaller than my original ROM, again save me some space. Yes remove bloatware as a lot of it runs in the background and it can't be uninstalled. Yes optimize the ROM for better performance, but please don't add a ton of other things that give to many options that become novilty items. I much rather have a Manufacturers ROM that has been optimized and debloated running fast and smooth than something that I will never get the full use of.

Of course this is just the way I feel about it. NOT TRYING TO START A FLAME WAR.
[Galaxy S 4 General] Indian Devil:
Is it?

I think ( Read in the forum itself) it will void my warranty even if I flash Official Samsung ROM via Odin.

Or am I wrong?
[Galaxy S 4 General] toeshot:
It only trips if you have the 4.3 installed and try to odin an older ROM official or custom ROM
[Galaxy S 4 General] Indian Devil:
So it's OK if I flash latest 4.3 ROM over 4.3 only?

It won't void the warranty, right?
[Galaxy S 4 General] toeshot:
I had a custom 4.3 ROM that was KNOX free and the Warranty bit was not tripped. I Odin the Official 4.3 and the warranty bit was not trip. I tried to Odin MD5 and it would not Odin and the Warranty bit was tripped.

I can testify to what I have done with my phone as for using Odin to flash 4.3 official to a 4.3 official (if that is what you are asking) I cannot say for sure.
[Galaxy S 4 General] Indian Devil:
Thanks mate. I am asking this only, lets hope someone can clarify this.
[Galaxy S 4 General] niranjan.homkar:
once on stock on 4.3 and you again flash the stock 4.3 over it, I don't think that it will be tripped.

It only trips when you try to flash any other non official samsung thingy with modified signature.

I flashed to stock 4.3 on my Note II and I was unaware about this Knox sh*t, rooted the phone and the Knox fuse was tripped and I was unable to downgrade to 4.1.2 again :(

Samsung has really messed up here.. :(
[Galaxy S 4 General] :
As far as I know flashing 4.3 over 4.3 will trip the knox that's why you can't fix your Touchwiz at home when you do; goodbye warranty! Sometimes it's hard to understand.If that trip the knox so every firmware file have different Samsung signature ? There is a optionin bootlader called "Write Protection" maybe it's about modifying knox flags.Maybe we should focus on Write Protection instead of unknoxing.So it will become easier editing knox flags.I just saying I don't have a big knowledge.

Note 2 users can unknox the bootlader.It have older hardware and it take 4.3 later but Note 3 have newer hardware and firmware.It was possible disabling old one.We have a proper info too knox isn't EFUSE.It can clearly editable flag/value or what do you want.

OFF TOPIC: I tried extracting system.img but it failed.I can extract my I9070 everytime but Note 3 firmware can't be extracted. (not .tar, .img file)
[Galaxy S 4 General] Daagen:
That way Knox would not be secure anymore. So its just the way how you look at it.. :p
[Galaxy S 4 General] My1xT:
4.1 hasnt Knox anyway...
[Galaxy S 4 General] toeshot:
KNOX will still be secure. The KNOX warranty flag indicates that another ROM other than the 4.3 has been install (at one point or another) This is viable for Samsung incase a corporation says that the KNOX security failed to protect their company data on the Samsung device. Samsung can then say you have modified the system on the device, hence Samsung isn't responsible for the corporate data loss/theft/coruption. The question is will Samsung honor your warranty if there is a hardware issue with the device. As for this security they have been trying to implement this since the SGSII with it's hardware encryption layer. Seems like they just now got up to speed on it.

All in All still a good device, you can still load downgrade A a ROM if you want, just not through oding. you will have to find a flashable version. You can still install custom recovery, custom ROM, Radio (I will try an older 4.1.X Radio with a 4.1.X ROM when I get the chance to confirm this). Nothing has really changed except the bootloader is not downgradeable. I am sure though that someone will figure out how to downgrade this soon enough.
[Galaxy S 4 General] CwestSide:
Thanks for the info . needed to know this too
[Galaxy S 4 General] slig:
Thanks for info. That's just great. As I understand it makes gs4 debranding from mobile operator software impossible. Wonder if it still be possible to flash GP edition. It looks like everything I loved in Samsung phones has been wiped by this step so the time is coming to move on. Very sad moment for me as I like Sammy's devices so much. :(

For now I'll stay with MGA. Maybe it would be better idea to switch to customs or GP edition. Thank God something told me to read first before updating...
[Galaxy S 4 General] CodeJACK:
My baseband has been stuck on XXUBMF8 for a few months now and Im kind of glad.

I've tried flashing all these new modems but none seem to apply. Guess I got lucky as Im only reading about all this stuff now.

At what point will an older modem baseband become useless?

I guess an enterprise will be allowed to apply policies to phones and if the phone does not have knox baseband then the user can not use it unless they upgrade. Not very fair at all.
[Galaxy S 4 General] DjeMBeY:

And WE ARE ON THE GOOD WAY !!!

---------------------------------------------------------------

FOR WIFI / SOUND Problems !!! after Upgrade / Downgrade !

1. Download odin 3.07 ( you have option NAND ERAS ALL )

2. Download MH8 ( If you are with knox ), / MF8 ( NON KNOX BOOT )

3. Download PIT

4. Odin - check NAND, PIT file, PDA AND START

5. After flash your phone wont boot ( stuck at samsung Logo )

6. Boot in recovery ( volume up )( original recovery )

7. Factory reset + format cache.

8. Will reboot automatically the phone

Hi,

First thing, thank you very much for your work. I really appreciate what you are doing for or phone.

Second thing is regarding the warranty. On any device which is using firmware (phone, router, DVR, etc) changing the producer fw will void warranty and that seems correct in my opinion.

Coming back to our phones, installing custom fw is done only by a few of us and it will void the warranty. Full stop, knox or not knox.

Until now we could erase the trace of this thanks to Chainfire, but was still warranty void.

On CM, first thing they are saying is that when you install the ROM the warranty is gone.

I am on MH8, unbranded, happy with the way it works.

When I will want to go for custom, I will root and that is. Never used triangle away on my previous phone, SGS2.

Sorry for my very long post.

[Galaxy S 4 General] ladyhaly:
That and how the phone can lose value once I resell it. I just don't think what Samsung did is justifiable in the least. Understanding their reasoning is one thing, but forcing it down on everyone and saying it in a way that would actually justify their decision is another.

Why do you think I care? The fact is warranty services for phones from the repair centers isn't universal. The fact is I want to tinker with my phone and set it back to how I want it. I should have the freedom to do what I want with my phone, and as of right now, I don't even want to veer off the stock ROM. Just flash a non-carrier one.

However, this KNOX thing is stopping me.

You telling me I shouldn't care if I don't work in a corporate environment is confusing, because this so happens to be done for their convenience. If it's so convenient for them, then why would people like them have a problem with it?

I care because I know for a fact warranty services where I live will use this as a reason to deny me of warranty rights. Now if you tell me, it sucks to live where I am, yeah sure. It does. If you can understand Samsung and justify what they did, then I hope you can understand me.
[Galaxy S 4 General] A.S._id:
Can of course I paranoid, but... We see only the top of the iceberg in the form of the user container. But the basis of the fact that once lost a guarantee can not be her return, there is still and other container- hidden service. It always kept all the history of the use of the device information about the user, the coordinates of movement, magazine calls. This means that besides that this device is not possible to steal, it as well is not possible to sell, because it is bound to a particular user. And who in the first place it can be interested?
