Nope, it will trigger Knox....

any idea how this behaves if you did not upgrade the bootloader files? (update with custom created odin tar)
aka could you downgrade if you still have old (MI7) bootloader?

[Q] (Q) May I ask some question about N9005 international.

Today I brought N9005 and pre installed android version is 4.4.2
For N9005 with kitkat I am very very newbie. I would like to ask

Thank for all kind for answer my question.
Ps.Sorry for my bad English.

You can't downgrade
Cf root will trip Knox
Vega won't trip Knox

Thanks for your answer. I will try to root with de la vega method.
As you told me I can not downgrade. In this case. If I flash with
custom rom JB version. What will going on.

Baseband : N9005XXUENA2
Build number : KOT49H.N9005XXUENA6
This is my device detail. If I root with De la vega method and
using odin flash tool flash N9005XXUDMJ7 rom pack.
May it possible or not. I no need to use Kitkat because
my app and game not support Kitkat.
Thank you for answer.

You're already on Kit Kat. Just root with cf auto root if you really need to use root. No knox friendly to root kit kat

Dont do this.. itll brick your device until you flash a stock kitkat firmware onto it again.
MJ7 is a JB firmware.

You can't go from Kitkat back to Jellybean.
Any thing you do to root it will trigger Knox.

as mentioned by ultramag69,
unfortunately the upgrade of the Android O/S since 4.3 and above is irreversible (one way ticket), due to sammy is keeping on developing its bootloader.
Not only saying 4.3 to 4.4. Even the same version of 4.3 got few bootloader patches, and the same 4.4 also have few bootloader patches. This bootloader things make the upgrade irreversible. Downgrading can cause you to bootloop (soft brick), & KNOX trip.
and there's no KNOX friendly root method for the newer bootloader 4.3 and above. If you need root, you will have to bear with the KNOX trip. If you want to keep the KNOX, don't root, and just use your device as per normal usage.
Cheers.

Root GT-N7100<4.4.2> without tripping KNOX

Hi XDA people,
Just found this workaround for rooting latest 4.4.2 stock firmware without tripping Knox.
This method downgrades the firmware(System & Kernel) on your device to N7100XXUEMK4 except for the bootloader.
Dont even try to downgrade the bootloader as this isn't possible.
What you need:
1.Odin v3.09
2.Stock official N7100XXUFND3 firmware on your device.
3. A device with Knox Warranty Void: 0
Procedure:
1.Download N7100XXUEMK4 Stock Rom from HERE
2. Open the downloaded file.You will find 4 .tar.md5 files and an Odinv3.09 zip file inside.
3. Extract the Odin file and setup Odin on your PC.
4. Next extract the file named AP_N7100XXUEMK4_2099172_REV04_user_low_ship.tar.md5
5. Load this file into AP tab on Odin. Connect your phone in Odin mode and flash this file.
( Note : You have to flash only the AP file from Odin. Do not flash the other files namely CP, CSC, BL)
6. Now once the phone has rebooted go back to download mode and check if Knox has tripped or not.
7. Next use Saferoot from HERE to root your device.
(You would find the guide on how to root using saferoot easily over HERE
8. Now if saferoot was able to root your device then you must be rooted without tripping Knox. :good:
9. Now you can easily flash your official firmware through mobile odin. Select Everroot option on Mobile odin while flashing the new firmware. In this way you wont lose root access.
Known Issues:
If after rooting you want to flash custom recovery via mobile odin, or via DR.Ketan's utilities app please note that it will trip knox.
Knox remains cool until your recovery is stock. The moment a custom recovery is detected knox goes 1.

Cant you just do this?
Use Mj5 bootloader and any rom 4.x
Flash Kitkat 4.4.2 via mobilOdin and root.
Make sure status is ok (use triangle away if not)
Flash latest 4.4.2 bootloader via Odin (pcOdin)

Surely it can be done that way.
This is for those who already upgraded to the newer builds.
Edit: FYI Triangle Away cannot reset Knox.

Ok.
What i mean was use Triangle away before you flash the 4.4.2 bootloader to get official status and binary count 0, the knox in MJ5 always stand 0.

But wouldn't flashing 4.4.2 BL trigger Knox? I got bit confused with @robalm method
@smeet.somaiya didn't some guy over at general forum under galaxy note 2 india told us that he downgraded from official 4.4.2 to stock 4.3 and his bootloader was downgraded as well?

I don't think flashing ND3 BL will trigger knox.
Most of the users already flashed ND3 BL from MJ5 while they were on DN3. It doesn't trigger that way.
And yes about that guy, he never mentioned any detail that he downgraded from ND3 to which firmware of 4.3.

I did read them. They got knoxed means they got a BL with Knox warranty Void 0. And @paarkhi confirmed it to me
And I really don't think it would trigger knox that way because the bootloader doesn't check the integrity of the firmware on your device when you're flashing the bootloader itself.
Also it doesn't trigger Knox while it boots up the system and finds unauthorized firmware.
Because we don't have Kernel lock and secure boot like on Qualcomm based N3.

Okay this is all too much for my brain to absorb at this time of the night ,i don't think i actually understand the difference between Knox warranty void and being Knoxed ,i guess since we install de-knoxed ROMs we can't get Knoxed ,just that our warranty goes out the window and we cannot downgrade beyond a certain OS right? If what i stated is wrong then i'll go to bed and dream of knox

Lol. It's paritally right.
Don't worry buddy I'll help you learn Knox
Being Knoxed is getting that extra line in the download mode.
But this doesn't throw away your warranty. Warranty is lost only when this extra line in download mode ends with 1 instead of 0

No feedback yet. But one thing i can say for sure that even if this method fails it won't hard rick your phone because we ain't downgrading the BL here.
And I found a similar method on S4 active forums. It seems it works very well.

Yes it would trigger by flashing unofficial firmware.
But here we ain't doing that too.
We're just flashing a older kernel+system partition (the whole PDA from MK4) that was vulnerable to root without tripping knox.

Note 3 Update Questions

Hello,
I have a note 3 SM-N9005 running on 4.3 and I just noticed an update that can be installed.
My basband is N9005XXUDMJ7.
Kernal is 3.4.0-2019540.
My question is can I root using towelroot without tripping knox?
If not is the new update ok to apply?
Thanks

As with any updates, I would suggest you have a backup of your data, just in case.
To root your device, towelroot will work and will not trip knox (if done properly).
You can see this post for the procedure : http://forum.xda-developers.com/showthread.php?t=2790108
Take note that you should upgrade to 4.4.2 before rooting.
Let me know if you need further help.

If I update to 4.4.2 will it change the boot loader also meaning then I wont be able to root?

You'll be able to root, no problem.

Is that because of my boot loader date?

What do you mean by that? The OTA update you'll do will take care of everything for you. No need for you to change your bootloader manually.

Ok so to 100% sure if I update to 4.4.2 then root using towel root it will not trip knox?

[Q] G900T software update = Towelroot gone?

I unrooted my G900T (previously rooted via Towelroot V2) using SuperUser so that I could update my firmware via Kies (OTA kept failing every time regardless of being unrooted). Now I'm unsupported by Towelroot... T_T
Has anyone else become unable to root theirs after the update?
Previous firmware: G900TUVU1ANCH
Present firmware: G900TUVU1BNF6

You can root using cf-root method be chainfire even if you are on the latest firmware
but be carefull it will trip knox and void your warrenty
if you dont want this you have to wait an update for towlroot to be able to root the latest firmware

I dont think towelroot will be updated seeing as geo works at google now...

Ah yeah, I was using towelroot precisely because I didn't want to void knox. Blah! I've only had it rooted for less than 2 months, so I haven't really done much to have it bother me anyway.

Or you could do a forum search and stumble across better options.
No need to wait for a towel root update.
The latest update may block the Towel root exploit.. but you can still use Odin to install a pre-update version of your stock firmware and [drum roll], towel root will work again. And no Knox increment.
Samsung may eventually add another qfuse to block this method, but for now it works well. You need to revert to a pre June 3rd build of your stock 4.4.2 S5 software to do this.
