I have read (<here> and <here>)
about new firmware versions that will not allow resetting the counter (warranty flag) to initial conditions when restoring to stock after after unlocking or rooting.
If the phone developed a hardware problem, warranty repair could be denied.
The firmware version "MGG" and beyond are reported to have this problem.
Questions:
Does this also apply to the m919 T-Mobile version?
Has anybody seen it on an m919?
Is it going out with an OTA update?
Or is MGG specific to the i9505?
I am shopping for a GS4 m919, and I want confirm that it has the "pre-MGG" firmware version before purchase.
Questions:
Is the ID contained in the "Baseband" ID string in the phone information?
Are there different identifier strings used on the M919?
The T-Mobile S4 has not received the KNOX Bootloader, it will most likely come with the 4.3 update. If anyone is on stock, I would recommend you guys disable OTA updates as you may get automatically updated to 4.3 with the KNOX bootloader.
for once...im dreading an update from tmobile
If I've already rooted and installed a custom recovery (Clockwork Mod), and nothing else, does anyone know if the 4.3 update with KNOX will still be usuable? In other words, will the phone still get an automatic OTA update and will that update install correctly?

i'm glad I read this thread. i was going to wait until i tried the stock 4.3 update before deciding to root and install custom ROMs. With KNOX coming, I'm just going to root ASAP. I like PA on my Nexus4, so I'll probably go with that for my S4.
So you guys are saying the new update with "knox" won't allow you to reset the counter and only that or will it stop you from completely rooting and installing custom roms?

Let me clarify some things. The KNOX processes and functions are already on the stock ROM, most devs remove them, though. So many of you with custom ROMs haven't seen anything related to KNOX.
What the new T-Mobile update (when it gets pushed out) is most likely to come with is a "KNOX Bootloader" which will introduce a thing called "KNOX Flag" which is similar to the old counter we're all used to. This is the counter that @Chainfire was successful in resetting with his app, Triangle Away.
Unfortunately, @Chainfire or anyone else for that matter, has not been able to reset the KNOX flag.
The KNOX flags is this:
0x0 = You have not tripped the KNOX flag.
0x1 = You have tripped the KNOX flag.
Again, once you trip that flag, rooting, flashing a custom recovery, etc.. there is NO way to reset it as of now. And any KNOX functionality on your phone will not work. But the worst part is Samsung will refuse warranty on your device if they see a 0x1 in your bootloader.
Another thing.. on the new bootloader, if you try to downgrade, even with an official Samsung firmware, it will fail and you will trip the KNOX flag.
So once you're on the new bootloader, there's no going back.
There's been speculation that there's an eFuse at play here.
Anyway, this is the reason why I am suggesting you all disable OTA updates and wait until a ROM is built without the new bootloader and all the functions (Wifi, MMS, etc.) are working.

Hey, its sammy we have to blame for this one :/ Not T-Mobile lol.
PSSSST! Don't let them know you are dreading it, or they might put it off longer xD
As to the OP.
The KNOX Warranty counter is rumored to be what is called an eFUSE. If this is true, then resetting the KNOX warranty counter will be impossible without taking apart your phone and replacing that specific eFUSE.
However, there are rumors that some root methods DO NOT trip this new counter. Is that good? Yes, is that bad? Yes. For those users who like stock kernels and just wanna root, this is okay for them. But for 99.999999 percent of us who love to flash new kernels and get more from our devices, then it trips the counter.
I personally congratulate Samsung as well as hate them at the same time for this. I congratulate them because what seems to be happening a lot is users flash a million and 2 things to their device having not one single clue what they are doing, thus bricking their 500+ dollar smartphone then claiming it as a warranty claim and getting another one. I also feel they are trying to flex their ego muscles too -.-
I also believe that if you have insurance, this does not apply. It is only for warranty claims. Which like you stated OP, it only means Samsung can choose to deny to repair or replace it. I have read a lot of thread before where users tripped the older binary flash counter, and still were given a new device. I honestly don't know how this is going to play out for the lot of us. For me, my warranty is over in a few months anyhow so i don't really care. But its still kind of a dickish thing Samsung is doing.
I am also hoping that we can extract the contents of the new update and keep our older bootloaders and create a flashable zip with the new update stuff and have it still work. I know there were some issues with the international S4 4.3 update but im not sure if it was entirely caused by the bootloader.

Where do you disable OTA updates on a stock S4?
Hitting "Software Update" takes me to a Boolean"Update Now" popup with no other option than choosing Yes, No or Wifi. No option to defeat future updates is offered.
Going into developer mode doesn't seem to add any pertinent options either (correct me if I'm wrong).
Clearly, Samsung doesn't want us to be able to disable updates unless or until we root, which I'm doing this weekend on the basis of this thread.

You indeed have to root to disable OTA updates.
Once the update hits im going to extract the system.img to get all the files.
Then explore where all of the Knox crap is and get rid of it.
I know I want be alone in doing this...all who develop for the S4 will be on top of it.
Someone will figure out a way to get around this Knox BS...

thats fine and dandy for us with existing phones.. I already removed all the knox crap from my phone, and will update but not kernel and do the same..
But what about all future phones.. If indeed the kernel is locked with knox and there is no way to remove it we are screwed for new phones coming out.

[SIZE=+1]There seems to be a lot of confusion and misunderstanding circling the forums with regards to Knox and the 4.3 OTA.
This is an attempt to clear things up[/SIZE]
UPDATE: It seems that people can find this thread, but are unable to actually READ the information presented. The most important note here is that if you are on 4.3 firmware, you can flash ANY rom you like. No, you are not tied down or locked into stock only or 4.3 roms only. AOSP roms will work fine as well. Now scroll down and READ EVERYTHING IN THIS FIRST POST.
What is Knox? Knox is both a firmware and a software component. The OS has Knox apps, and the MK3 bootloader has a Knox component too. Having Knox apps does not necessarily mean you have the Knox bootloader, or vice-versa.
How does Knox work? Because Knox is both in the OS (apps) and in the firmware (bootloader) it works in two ways. The OS components prevent attempts to obtain root access and make rooting with these Knox apps a pain in the butt. Fortunately they can be removed. In the firmware component (bootloader), Knox works to prevent the flashing of custom kernels and recoveries. If you flash a custom rom or custom recovery WHILE on the Knox bootloader, your Knox flag will be tripped and your Warranty Bit will go from 0x0 to 0x1. The Knox bootloader cannot be downgraded to, say, the MD4 bootloader because of special protections built into it. If you attempt to downgrade it, your phone will instantly brick.
Can I get root on the Knox-enabled update? Yes. For those of us who DID NOT take the official OTA and DO NOT have the Knox bootloader, we can get root on 4.3 by injecting it and removing the Knox apps. For those WITH the Knox bootloader, you will need to wait until a full stock MK3 tar is available, which we can then use to make an Odin-flashable MK3 stock rom with root injected using the de-la-vega root method.
Can I downgrade while on 4.3? You can flash roms no matter what Android version they are. That is perfectly fine. But you cannot downgrade the bootloader if you have the Knox bootloader, or else it will cause your bootloader to become corrupted and give you a fancy paperweight. Again, for those who DO NOT have the Knox bootloader, you needn't worry about this/downgrading firmware since the Knox bootloader is what prevents you from doing this. Downgrading your bootloader includes: attempting to flash full stock tar of software versions < MK3, etc.
How can I tell if I've got the Knox bootloader?
Boot into download mode (through custom reboot menu, or by powering off then holding Power+Home+VolumeDown and then VolUp when prompted). If you see a line that starts with the following, then you've got the Knox bootloader. I will insert a picture showing how it actually looks soon

No way to remove bootloader Knox ATM.
I've seen several posts mention "tripping KNOX" or "voiding KNOX." What does that mean, exactly, regarding rooting a phone? Does it just mean it voids the warranty if you need to get support from Samsung/Sprint? Or are there other adverse effects?
Mostly just a visible warranty void.
Samsung bought crapple disease. So sad, but its my excuse to buy a nexus.

As said above, a voided Knox is mostly just a highly visible warranty void. Your local Sprint store may or may not care, or the specific Samsung rep that you deal with may not care, but it's easier just to not have to deal with it to begin with.
Does this mean there is already a touchwiz 4.3 ROM we can flash or do we still have to wait?
Sent from my SPH-L710 using Tapatalk
The biggest thing here is the fact that there is no full tar file to restore. So even if you do not care about knox or warranty. If something goes wrong with a flash or anything else you can't use an older tar file let's say MD4 or LJ7 or anything because you will end up with a brick. There is nothing to use to ODIN restore your device. Once you go 4.3 with Knox you have to stay 4.3 and even if you wanted to stay 4.3 and wanted to restore that there is no tar file at this time.
Have a great day!
I have a question I think we talked a bit about the problems the knox bootloader brings into the system. My question is the opposite what does it fix / change?
Im thinking along the lines of somebody modding the update so an old bootloader would be with the new rom would that be an issue? I think i remember hearing something about wifi being the problem but any clarification would be nice.

Right now, wifi is broken with the old bootloader and 4.3 rom...happened on the other devices too (tmo s3 and sprint s4)
But there is a fix: flash at&t kernel. But it messes up screen rotation. So i'm trying to come up with another fix that will let wifi turn on properly and let screen rotation work properly too
You = rock. Or some other awesome thing.

So is this Knox a Sprint thing, or a Samsung thing?
I can understand the reasoning for Knox(money) but, dang, I guess it's a dog eat dog world out there.
This doesn't affect CyanogenMod does it? I'm scared...

This would be a we-can't-update-the-bootloader thing lol. And we can't do that because it has Knox, which is Samsung's doing
This shouldn't affect any AOSP roms because it uses a different kernel and builds its own WiFi libs

From what I've read Knox is Samsung's attempt to provide strong security to their phones for the enterprise customers. As you can imagine, allowing system level access to files can be used to get around a lot of security measures that IT people would like to enforce in their client's devices. It makes sense at the enterprise level, but it's a pain for anyone who want's to mod their phone.
So I think the answer to your question is, unless you are using your phone in a locked down corporate environment then there really is no advantage to Knox. Too bad it can't be turned off, at least not officially.
Hi all
Quick inquiry and I didn't see an exact answer to a question that I have. So I have a note 3 rooted and knox flag currently set to 0x0. I was reading I think on here and some other fourms that knox has locked the bootloader. I want to flash a custom recovery and I know it will trip the knox flag. Is the bootloader locked already or am I able to load custom recovery without any issue?
Do you have the T-mobile version? If so, then no, the bootloader is NOT locked.
Flashing a custom recovery WILL trip the Knox flag though.

Hi. I kind of in the same situation.
I am a Note 2 user since it came out and have tried many ROMs without problems. I recently upgraded to Note 3 and I haven't touched anything (rooting and flashing) because I remember reading before about some problems with Knox and eFuse or something. I got a T-Mobile note btw.
Do I have to treat Note 3 differently when rooting and flashing because of this knox, efuse issues?
I tried to look for a clearer answer but I'm still hesitant to proceed. Or is the process the same as rooting and flashing ROMs on Note 2?
Also, I have a Jump insurance with TMO, is this going to have some problem if later I have to claim replacements or upgrade? Thanks a lot. Really appreciate the help.

Well, from where we are right now with the Knox counter, if you flash ANY ROM or Kernel, then the Knox will trip, and will void your warranty. You can root using Root de la vega, or Kingo root without tripping the Knox counter.
I am not sure from a T-Mobile standing if they will give you a hard time with warranty if the Knox is 0x1. I have tripped my Knox counter, and have Jump also, but I honestly don't care. I am sure that SOMEHOW in the future we will be able to reset the Knox counter....I hope anyways.

I'm thinking of upgrading from my GS3, non lte, to the Note 3. As I've looked around the forms here, it would seem as though Knox is an added security measure so t-mobile can more easily detect root?

Knox isn't really for T-mobile to detect root/custom firmware but for Samsung warranty. A fair amount of people on here have stated that they still sent their phones in to Sammy for warranty and they still got their phones fixed. T-mobile really only look for cracked screens, water damage and that the phone powers on and boots up. Not to say you'll never have an issue but i would say it's not really that big of a deal to trip the Knox counter. Especially if you bought the insurance like Asurion. I don't think they even care if your rooted and ROM'd
Awesome. My concern here is that I would be disqualified from the jump program... I'd like to get the Note 4 as soon as it comes out.. Is there currently any way to root and flash a room without tripping Knox? Or can we only root without tripping Knox?
Before this gets locked, yes you can root without tripping knox. As mentioned knox is for samsung to deny repairs if they see fit (if the phone is sent to them). Tmobile could care less if the phone is rooted or not. You just have to be careful about warranty repairs for samsung, thats what they may or may not look at.

On the old 4.3 firmware yes you can root with Root De La Vega and not trip the Knox counter but once you put ANY custom recovery it will trip the counter. Now on the OTA 4.4.2 that was released on Wednesday, the only 2 current ways to root (TWRP or Philz CWM) will trip the Knox counter no matter what. So until something comes out like an updated ROOT De La Vega, there's no way to even root without tripping the Knox counter.
Also from what i read, RDLV isn't being developed anymore so unless they decide to do something with it for the all the 4.4.2 releases hitting phones these days there may not be anything for a bit to root without tripping knox.

Did I miss something? Is there a way to Root 4.4.2 without tripping Knox? I don't care I've tripped Knox the first night i had my N3 but I didn't think there was a way. Kningo and RDLV i thought borked the phones and caused bootloops.
My t-mobile store says that if you root your phone then it voids your warranty, so obviously they won't allow me to upgrade... So I know they check for it.. How is it you guys have stores where they don't seem to care?
I've got a new s4 coming from my insurance plan Cuz I broke my screen.
Is there anyway I can get twrp installed without having to sit down at a computer? So I can restore my backup and have it root itself? Help much appreciated.
Search for Towelroot. I believe it will root the Tmo S4 without tripping the Knox flag. I don't think it requires a computer.
And, then once rooted you can install TWRP Manager from the Play Store.
TowelRoot will give you root. When you flash a custom recovery it will trip Knox.

Your new phone will come with 4.3 or 4.4.2. Both have Knox Bootloader.
TowelRoot will give you root. When you flash a custom recovery it will trip Knox. The only way to avoid Knox is to keep the stock recovery. And it will not allow you to flash custom roms.
TowelRoot root is a apk. You just run it and your done.

That seems unlikely. How is everybody else flashing custom roms on newer S4s?
I'm seeing things on Google that suggest I can just uninstall knox. If I uninstall it first, then root, will I be ok? Or if I disable it while rooting?

The Knox flag is a indicator to Samsung that you've installed a Custom Recovery. They instituted the check and the flag in the boot loader for 4.3. All the new phones come with this and there is no way to downgrade to a bootloader that doesn't have the check. Unless you are using the phone on a secure company network that requires it, Knox doesn't affect you in any way. Some people have claimed that it MAY cause you problem returning your phone for warranty, but at this point NO ONE has shown that they have had any issues returning their phone with the Knox flag tripped.
You can verify your bootloader, and view the flag's status once you get the phone by going into download mode - power off the phone. Then, hold the Vol Down button while powering on the phone. Hold the Vol Down until you get to a screen that has a Warning about Custom OS. Press the Vol Up button, and you will see a screen with a very small font and the first line will say "ODIN MODE" If your bootloader has the Knox check and flag, you will see line that says: KNOX WARRANTY VOID:. Next to that line with be either 0x0 or 0x1. If the flag is tripped, it will say 0x1.
If you don't have that line in your bootloader, then you don't have Knox, and you should be able to do what you want. However, if you want to keep your phone Knox free, you won't be able to do Over The Air (OTA) updates. You'll have to manually install ROMS, and never flash an updated bootloader.
I've tripped my Knox flag by flashing TWRP to my phone and have never worried about it.

Ok tripping it just means it's telling Samsung im messing with it?
It's not actually preventing me from installing custom recoveries or roms?
I thought he was saying I wouldn't be able to do it Cuz of knox.
I don't care about tripping any flags, I've got the premium insurance plan. That's actually how I just got the new s4, by filing a claim.
That's the nice thing about insurance on these devices, messing with the bootloader and installing roms Falls under accidental damage, which is covered.
Sure the deductible is 175 dollars.... But just to replace the glass on one of these can cost upwards of 300 dollars. Worth the 11 dollars a month n deductible. I will be canceling it now though. If this one breaks, I'll just upgrade.
Thanks for the help guys.

I don't care about any flags, just so long as I'll be able to flash stuff like normal.
The SIMPLEST SAFEST and EASIEST would be to just install My Backup Pro.
it has a "Migrate" mode which allows you to send all that you wish to transfer to the new device and on that new device all you need to do is add the app and instead of "Sending" the data, just select "Receive". (takes only seconds) That way you won't muck up your warranty on the new device till you're SURE there is nothing wrong with it... (just coz it was "refurbished" does not mean it works flawlessly! :>)
Aloha and Good Luck!
Thanks for the info. But I disagree. It seems I just root with this towelroot' install twrp' and restore.
However, I'll be installing a clean rom, insane v9, and reinstalling ask my apps from scratch. Just start brand new.
This brand new S4 will last me till the "sapphire glass" S6 is released, for sure.
