My happily rooted GS4's screen died and I took it Sprint for a replacement. They gave me a refurbished GS4 SPH-L720 with Android 4.4.2 and this build/baseband L720VPUFNAE. I've spent some time searching and I'm still not sure I've got the latest info on this:
Can I root? Based on this thread I think I can use CF Root but I'm not sure.
Will rooting trip the Knox flag and possibly void my warranty? Based on my searches, yes, I think it will trip the Knox flag. As of now there's no way around it.
Can I downgrade without tripping the Knox flag? No, I don't think I can.
Can anyone confirm that this the latest status on NAE? I'd rather avoid tripping the Knox flag, just because, but I'd like to have root back for RoamControl, Titanium Backup, and Tasker. And anyway, if the phone fails again I'm pretty no one at Sprint will be looking at the Knox flag when I go in to switch it out (or will they???).

Alright, where to begin.
I've owned quite a few Samsung phones by now and I've rooted every single one of them and installed custom recovery and ROMs. But with KNOX on the S4 this has made me unsure...
What will happen to my device when I root it now? I figure it'll trigger the Knox flag to 0x1. What are the drawbacks of that? Will it affect the function of my device?
And is the rooting procedure done as usual with Odin like on the S3?
And maybe most of all, is it worth rooting the S4 and installing custom ROMs?
Many questions, but I haven't found any real answers to any of them...
Nothing will happen to your device when counter z 0×1
Drawback z you'll void ur warranty & youll not get official updates if u r on I9500.If ur on I9505 then triangle away can solve both problems.No function gets hampers until you really mess with ur phone but that's after root
Yes the procedure z same
Well if ur on I9500 then there r only customised stock version nothing much only debloated or deodexed.If ur on I9505 then definitely worth it

Triangle away dont do much with the knox . Once trigger there is no way at the moment to reset this.

What happens when you actually get Knox flagged to 0x1?
You basically lose the ability to install Knox softwares, and your device will be flagged as 'insecure', which means if your company allows employees to bring their own device to work for accessing corporate emails etc and they use knox to keep security, your device will not allow this. However, you will still have the ability to use future samsung firmware releases even though you have the knox flagged.
How do you trigger Knox?
You still can root your phone with CFautoroot, but that will trigger knox to flagged to 0x1. If you try to downgrade your firmware, knox will also trigger to 0x1, therefore, once you upgrade to new bootloader, there is no way to go back to old bootloader without knox. (I would suggest if you do not want knox, but you want the new firmware, you've got to manually flash the modem.bin files using Odin)
Lastly, there is still a big question mark as to whether Samsung will actually service devices with knox 0x1

I agree with you except last words. Modem has nothing to do with knox... flashing a different modem version from rest of FW version (ROM and CSC) will probably give some data or voice problems, and he will still have the same android 4.2.2 version....
What I suggest if he wants last FW, is just flash it, root it, delete all knox files, assume he will have knox bit activated, and enjoy it.
I recently purchased a SM-N900W8. Love this device, just retired my S2 which i messed around with for a few years and never had issues...
I neglected to do research on XDA (Big mistake) before rooting it and had no idea about the repercussions of this KNOX issue.
I used this method to root it (http://galaxynote3root.com/galaxy-note-3-root/how-to-root-galaxy-note-3/)
I successfully installed CWM recovery and SuperSu and the phone is rooted. I had no intentions of installing Custom Roms just yet just wanted to be able to use some of my favorite apps that require rooting. The phones Current Binary and Phone status have both been tagged custom but my KNOX Warranty Void is still tagged at 0X0. Needless to say maybe I got lucky?
I was hoping to Revert to Stock and Unroot so I could follow this method instead (http://forum.xda-developers.com/showthread.php?t=2498850)
Is there anyways to Accomplish this without tripping the KNOX counter? I've been scouring the forums for several hours trying to find a concrete answer but cannot.
I have downloaded my stock firmware (http://www.sammobile.com/firmwares/3/?download=26653)
Any help or suggestions would be greatly appreciated. I have included a screenshot of my device info. I apologize in advance if this issue has already been addressed.
Thanks,
-Rob
For device info and Knox warranty status, you can use my app Phone INFO ★Samsung★ to get more detailed info.

Why did you even install CWM if you didn't need it ?
Why do you want to remove it ? Don't fix it if it ain't broken. De la vega will trip Knox in 4.4, so leave it as it is.

Will do. Was just worried about official updates and warranty if phone still says custom but knox is not tripped. But bell outsources another company for repairs and doesn't send back to Samsung directly so I probably don't need to worry to much..
I used CWM because I've used it for a couple years with my S2 and enjoyed the features so when I saw cwm was avaliable for note 3 I jumped on it.
But there is no way to revert to stock without tripping count?
Thanks.

Flashing stock using odin should rever everything back to stock and possibly not trip knox counte, I am saying possibly cuz nobody has tried to flash stock recovery and try to keep knox cool as custom recoveries have tripped everyone's knox AFAIK. But your phone FW or maybe something else might make your device an exception.

I will leave as is for now until more info on the subject surfaces. As much as I want to try to flash back to stock recovery and test your theory I will hold out and not mess around with CWM or mess with apps requiring root to much incase it decides to trip the counter.
Thanks.
I have Galaxy S4 tri-band SPH-L720T with L720TVPUBNC6 kitkat 4.4.2. I understand that rooting this phone will set Knox to 0x1. But i need Knox to use phone at work, unless someone knows of an alternative to it? I'm thinking an already rooted NC6 tar flashed via Odin will not trip knox, is that right? I've seen rooted stock roms before, but i could not find rooted NC6. Is there a way i could mod/root the original tar.md5 file and then flash it? Some help would be great.
Thanks a lot
No way to root without tripping Knox as of now.

What are the odds of someone finding a way to root Kitkat without affecting Knox? If Knox 0x1 only voided the warranty and did not disable it then i would not care about it. I've found alternatives to Knox, that may have to be enough for now.

Any methods that you will find that accomplish this have been guaranteed by Samsung to be quickly put to bed.
They're all for being able to root but they have to assure Enterprise MDM users of data security.
It's why I use the G2 for Airwatch and leave the S4/S5 for dev or home use.

What about this method below i found on xda after a lot of searching?:
Keep Knox 0x0 root- Kitkat upgrade

If by G2, you mean LG G2, then yes it's all LG or HTC for me now. And Airwatch is on the top of my list of Enterprise MDM, This begs the question, if knox is tripped will Airwatch or another MDM still work? Or, since Knox is in the bootloader, can Samsung lock the phone to only use Knox?
Was looking at some random threads and found this:
http://forum.xda-developers.com/showpost.php?p=60775776&postcount=5
Any tutorial on how to do this?
Also is there any value in keeping KNOX 0x0 now that my warranty has expired? It's not that the S5 can use Samsung Pay right? It needs that MFE(?) chip?
Thanks

If you have KitKat on your phone, you can follow this guide.....
http://forum.xda-developers.com/showthread.php?t=2843044
You will be able to towelroot your device and flash a pre rooted lollipop firmware.
If you want to flash and root the latest Lollipop firmware for your device, you need to towelroot while still on KitKat, and then use Flashfire to flash (and root) your chosen LP firmware......
The Flashfire thread will help guide you....
http://forum.xda-developers.com/showthread.php?t=3075433
Concerning the value of keeping Knox at 0x0, that depends entirely on what you want to do with your phone......
Yes, Knox has a direct bearing on warranty, but as you said, your warranty has expired, so that doesn't matter.
It also has a bearing on whether you can use your device on business (enterprise) networks.....tripped Knox = no access.
If you decide to go back to full official, tripped Knox has been known to impact OTA......Tripped Knox = no OTA Upgrade
Don't quote me on this last one, but I *think* I've read that tripping knox breaks S Health functionality......I may be wrong on that one though.....

I've tripped knox, and my S Health works fine.

Hey all, it's been a while since my rooting days but I wanted to check in and ask this: Is there a simple way that the manufacturer can tell if you have rooted the phone? I ask because I'm a verizon employee now and they're more strict than my previous employer was, At&t. I know samsung used to have a counter on some of their devices but wanted to check in with today's current root methods. And if there is a way they can tell, can you reset it to zero after flashing through odin or another method?
TIA!
There is Knox warranty void which is tripped when root and when tripped it's permanent. There is no way to undo it other than changing mainboard.
Knox is an efuse, hardware based thing.

But what about the exynos version. is the knox flag still there if you go back to stock?

It is. But it does not have an efuse so could potentially be reversed. However nobody has found a way to do it as of yet.
Sent from my SM-G935F using Tapatalk
everytime you'll flash something, the knox counter will be from 0x0 to 0x1, which means your warranty is void.
Up to now there is no known way to turn it back to 0x0
