[Q] "Knox" firmware and the m919 version?

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.

that's also why I paid 400 bucks for a T-Mobile sgs 4 and I am using it on at&t... I refuse to pay or support a phone with a locked bootloader.. matter of principle...i would ditch att if T-Mobile had decent service in my area.

[FAQ] KNOX and you

[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

I hope the above helps to clear up some confusion. Ask questions if you are still concerned and I will do my best to answer them.

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...
edit... I remember reading about a brick api or command, I never executed it, sounds nasty, is this what they use to brick peoples phones if they try to "hack" it?

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.

Things to consider!

Hi guys I have my galaxy S4 close to a year now and now that I paid off the phone and now im ready to rootand do the whole 9 yards.
So I used to have a htc sensation before and I remember it needed to be s-off in order to gain root access, so does this also applies to my s4 or is rhat just aplicable to htc phone?
Now let me give you guys my specs:
T-mo us SGS4.
Stock rom, untouched.
Stupid knox installed.
Kit kat 4.4.2
Baseband: M919uvufnb4
Secure boot status: Samsung
Device status: official.
So I read that knox trips up and correct me if im wrong it lets samsung knows or something like that so you cant claim for warranty purposes????whats the best custkm recovery for the s4? Cwm or twrp?
So I wanna do:
1. Root
2. Install custom recovery
3. Remove tmo and samsung bloat. (Does anyone know which are safe apps to remove and where to remove them from?)
4. At the end of the day have a fully working S4 rooted with less junk in it.
As I think of more stuff to do I will post, or if you guys have better ideas, steps, or anything just let me know. All your help will be greatly appreciated.

S-Off is an HTC thing. It doesn't apply to Samsung devices.
Knox will be tripped and they COULD prevent you from filing a warrenty claim. But that hasn't been a big deal so far and your phone is outside of warrenty anyway it sounds like.
Search for CF Auto Root. It makes rooting this a really simple 30 second process. (No downgrading firmware and all that jazz that you did on your Sensation using PM5110IMG files or whatever they were called.)
Custom recovery flashes in seconds as well.
You'll have to decide for yourself if you like CWM or TWRP. We don't allow discussions on XDA about 'which is better'. Both have their advantages. It depends on which you like best for your use.
There is a list of 'safe to delete' bloatware around here somewhere. The search feature will help you find it. But you can also just make a Nandroid backup first and delete whatever teh hell you want. If you break it, just restore.

Just a comment on CWM. I tend to use it more but had issues flashing multiple ROMS with it, kept getting an error about "4 arguments accepted, received 5" when it was partitioning. In the M919 developers forum someone recommended TWRP and that did the trick for me. I don't know if its KitKat or s4 related but for now I'd suggest TWRP, CWM has not been working for me.

Thanks bro ill keep that in mind

G925T Do's and Don't's

Hey guys! I've been rooting and flashing phones for a while now, however this is going to be my first Samsung device and it seems like the rooting proccess is different. Just ordered one off of eBay and it's coming in some time next week.
I've been searching and reading countless threads on how to root and flash the S6 Edge, but still wanted to know all the do's and don't's when flashing the phone.
First thing I want to do is obviously root the phone when I get it. I don't know which s/w version it will come with, so what will be the easiest method to root the phone?
From what I've read, flashing a custom recovery such as TWRP will trip KNOX. Besides that, what else can trip it?
Also, it looks like flashing a custom kernel is required to root the phone. On the LG G3, for example, I could just flash a SuperSU zip from recovery to root the phone. Does it not work like that with this phone?
Thank you for your help.

Lastest 5.1.1 requires custom kernel to root. If the phone comes with 5.0.2, imo, do not upgrade, use ping pong root (google it) to keep warranty.

Seconded. From what I understand, there's no way to root and keep KNOX untripped and have your fingerprnt scanner work on 5.1.1. You either have a tripped KNOX or a broken fingerprint scanner. If you're on 5.1.1 and dont care about KNOX (I don't) I recommend UniKernel to root. I've found it helps a lot with battery life, especially when paired with XstreStoLite ROM.

Samsung Pay will be broken too.

I have UniBase on my Rooted S6 Edge. I have had no improvements on battery. I have to charge it atleast twice a day. Which is okay, But rather annoying when in the middle of a conversation and have to either charge it or it dies.

Try XstreStoLite 2.4. It comes with UniKernel v9 and that combo has done wonders for my standby battery life. Under use, the battery life is about the same, but standby has increaded drastically.

Don't root until you're sure you won't need Samsung's repair service.
Use it a lot and stress it to the limits with hardcore games to find out if your S6e gets the blocky screen disorder or 8bit graphics corruption problem. Mine goes 8bit when it's cold outside or when games heat up the SoC so it's going in for repairs.

Guys i just got a s6e tmobile version as a gift
I am in india so there is no need for tmobile rom and its junk for me coz its useless
Now can i flash 925f or 925i version on it?
Is there and hardware diff between between international version and t mobile version? ( coz it will be a heart-breaker) for me
Please let me know asap coz i cant understand most things as of now eg the shoot.bin file you keep talking about etc
Also what does that update do which you guys talk about (OCJ vs OJ6) etc.
Also warranty is not an issue as i wont get it anyways it being inported...lol

Down side of rooting ?

Hey there,
I've owned the Note 10+ (Exynos) since release and i haven't rooted it once. I remember the last phone is the note 8 and i did root it, but i remember when i wanted to return to stock to sell that phone i ran into some trouble.
For example the Samsung Pass, Samsung Health Apps etc... don't work anymore after your root your phone, is this still a thing ? Because i'm considering rooting the note 10+ now and i need to know if i can successfully get everything back the way it was before rooting ?
Any help or advice would be appreciated, thanks

hello. yes rooting is a bit of a problem nowadays. Samsung REALLY does not want you to root their Androids for whatever reason. Here are the disadvantages:
1) When you power up the device, a FILTHY boot-up screen pops up and takes 8 seconds and a button press to fully boot the device [see the full details and EXYNOS ONLY bypass here: Boot Pop up remove
2) The KNOX counter [hardware fuse] trips and goes 0x1 [Some devices get OTA updates after locking the bootloader and flashing full ODIN stock, but didn't happen for me. Also it voids the warranty]
3) All the KNOX secured apps [Secure Folder, Samsung Health, Pay etc.] will NOT work [there are bypasses for Samsung Health, Samsung Music and Secure Folder but say goodbye to Samsung Pay]
4) Samsung will refuse to repair your phone and you have to look at 3rd Party options to repair if anything goes wrong. [no bypass to that]
5) Once you unlock the bootloader, you can never lock it again [ idk much about this one, some people say you can lock it again. Gotta look it up ]
Also rooting with TWRP in of itself is a gigantic hassle nowadays [I really miss the days when we could just flash TWRP with ODIN and call it a day].

I mean as far as the boot up issue its fixed so that's fine, in terms of the counter, even if i restored the stock rom and removed root i won't ever get OTA updates ?
Ahhh i seriously hate samsung now ! let me mess up my phone the way i want

Well, that is the price to pay to really ensure a safe device, specially when using banking apps, and corporative enviroments, knox is really good in this regard, the e-fuse is a total warranty for knowing if a device is compromised at deep levels, so, that is how things are these days…

The e-fuse status (0x1) on the bootloader screen can be spoofed to look like it hasn't. Just checking the bootloader before purchasing a 2nd hand device is no longer a guarantee that you have a "secure" device...
This means that if you do get a device that looks secure you might actually get a few nasty surprises when certain apps just won't work or if you try to flash OTA updates yourself through ODIN...
Buyer beware...

I mean as far as the boot up issue its fixed so that's fine, in terms of the counter, even if i restored the stock rom and removed root i won't ever get OTA updates ?

yup. even after you full flash stock, it's still gonna be 0x1 and no more OTA updates. But you still can do firmware updates with ODIN (remember it wipes everything including the Internal Storage). Tons of guides on Google, find one.

Just a tiny correction to this thread: it's not true that you can "never" get ota updates ever again. If you flash stock again, you will receive OTAs.

As for samsung pay, my country doesn't support it, so no loss there, s-health you get working with a build.prop line, and secure folder is more or less a gimmick for me. As for getting your phone warrantied, i had my friend get his rooted s6e+ replaced for dead camera pixels with no issues. And from what i read european countries have laws separating hardware warranties from software. But i could be wrong on this.
With that being said, unless you have a specialised application for it, rooting isn't worth it anymore imo. It was back when touchwiz was a bloated pos and flashing cyanogenmod gave you a really noticeable advantage, but samsung caught up software wise.

Rooting and installing a custom rom takes me back to good old htc hd2 days.... I've rooted all my phones up to the original pixel. After further looking into rooting and how it can affect security I decided to opt out of rooting for the next 4-5 years. I feel like back then, the OS weren't this customizable as todays phones are. I do miss Xposed Frameworks though

As some posters above say, unless you want very, very badly some app that requires root, it is not worth the hassle and the security issues, I really loved Viper sound, which requires root, but, I decided not to root since the note 7, now samsung one UI gives a very good customization, I do apreciate Knox, and some banking and streaming apps refuse to work on rooted devices, so, I said bye to viper…

Not being rooted, I really miss titanium backup. Every time I get a new phone I end up losing progress or data in some app or other, usually a game. There was one game I had spent a decent bit of money on, years ago now, on my note 4, and it didn't transfer properly to my note 7, and I lost all my progress and the money I had spent on it.
I really feel like consumer protection laws should mandate that the manufacturers can't make rooting impossible like they do. I don't care about losing knox or Samsung apps, heck, part of why I root is to get that crap I don't use off my phone! I miss lineageos. Samsung's android customization isn't to my taste.

I agree with you about root, somebody buys a phone, therefore that person should be able to do anything to it, but, for other part, if rooting is all that important for you, you might very well cosidered getting a rootable device, I rooted my devices in the past, begining with a S3, these days I just miss Viper, but, considering how samsung has progressed with itd UI, I no longer think about root, furthermore, I use a number of apps that do not work when root is detected, so, in the end every one has to think carefully what really needs before getting a device

the only thing i miss on stock, are proper backups as in TWRP or in Titanium Backup, as a lot of things are not restorable with SmartSwitch. also i miss the possibility to completely uninstall bloatware like facebook or netflix and others. i see no reason, why these are part of the OS. CCSWE is quite a big help in that matter, though. for OTA, you can have them, when you re-lock the bootloader and odin stock on the device (at least on the S10+)

as for backup I think I heard about a software called helium, which backs up apps w/o root. Also you can disable/remove bloatware using a PC and ADB w/o root. Here you go: https://www.xda-developers.com/uninstall-carrier-oem-bloatware-without-root-access/

thanks a lot for correcting me. Even after I flashed full stock on my Tab S3, it would not detect OTA updates and some updates totally soft-bricked it. Editing my post for correction

i went fir CCSWE,regarding disabling.
