Dear XDA,
I come from the HTC One forum and I've sold since I've had camera issues numberous of times.
I decided to switch to an SGS 4, currently on 4.4.2. I have the i9505xxufnb9 variant.
I have a question regarding root.
1. I do not have knox installed yet, should I install it or leave it as it be when using CF-auto root? I'm currently on 4.4.2.
2. Is CF auto root compatible with my variant?
3. What version of Odin should I be running? I guess this is the most important. I don't want a sketchy Odin.exe that comes pre-set up. It might have some setting on that erases something that is crucial for my device.
4. Is there some sort of bootloader unlock I need to do first? My device is unbranded GT9505 version with the above written variant.
5. How likely am I to brick my device? I mean I come from the HTC one forum which was fairly easy. Setup fastboot and unlocking the bootloader did the job.
6. I came to understand it WILL trigger knox, does it mean voided warranty here in the Netherlands?
7. I understand that SuperSU has an option to unroot at any given time. When I want to return to stock for say warranty purposes, Can I download triangleaway, run it, and then unroot using SU app?
Thank you so much for your time!!
No one?
Cf autoroot comes with correct odin, if you do not have Knox don't install it, (you automatically get it if you took an ota). And no bootloader unlock is needed almost all Samsung devices come with an unlocked bootloader, and the only way you'll brick your device is if you flash something not meant for your phone or if you have knox and try downgrading your firmware...
And if you do have knox, rooting will permanently flag your device as modified with no way of going back. If you don't have knox you can use triangle away to reset the flash counter.

I'll make sure to give you your thanks tomorrow . I also got alot of help from the ask everything thread, thank you!
Hello everyone,
Until today I had official firmware I9505XXUGNF1 on my GT-I9505 that I rooted with TowelRoot (great app by the way).
Knox 0x0.
Today I upgraded to I9505XXUGNG8, and I lost the root (of course), but now TowelRoot can't root my phone.
Is there any solution to this or another method to root without tripping the knox?
Thank you.
Delete everything related with knox via titanium back up (popular) or sd maid (personal pref) then root with cf-auto root. Or look up a thread on xda named triangle away...

1. I think I need Root to delete Knox apps, don't I ?
2. Will this prevent the Knox status from showing 0x1 or is it only by software level ?
3. I prefer a method that skips the Knox counter in the first place (like TowelRoot) and not messing around (with TriangleAway for example) trying to reset what I could avoid. Also, I always prefer a cleaner method (that requires the least number of changes to the system). Besides, TriangleAway doesn't reset the Knox counter, right ?
Thanks.
Oh yh sry. Just look up thread on triangle away i think it does reset it. Deleting knox app dosent change nothing it system unless you use it. Infact deleting knox gives you more space.
Or start from scratch- delete data/cache via recovery delete and reinstall usb files on your pc, flash firmware, and try rooting again.

KNOX counter cannot be reset even by using Triangle Away. No matter how many data wipes you do or
caches you clean.
Once it it 0x1, it remains 0x1.

Yeah. But what samsung did now was, that they fixed the loophole in KNOX 2.0 OTA upgrade which geohot was using to gain root access.
Wait for a while and see if he gets another loophole to root.
Press Thanks if I helped

Surely someone has root on ugng8 using towelroot?
From what i know ppl used cf root and custom rommed there phones. Why stick to samsuck?
Try this - Worked for me

Hi LionGod8
I had same problem with my GT-I9505 (jfltexx), just google " root I9505XXUGNG8 " (without quotes)
should be top result from nasirtech blog .
I used Odin 3.09, make sure to wait for pass.... Might take a little while.
checked with root checker , all good.

i updated too and lost root, and then found out that towelroot is no longer working! any help on rooting without knox 0x1 would be great.
Flash a lower kernel and then use towelroot and then flash back the correct kernel for your rom. Knox will be 0x0 but system status will be custom.

Hi glosman,
Found a page on w0lfdroid.com that backs-up what you suggest and provides kernel links.
I am plucking the courage to try this.

So now I have my sd-card back under my control no thanks to google kitkat. Also knox warranty still 0x0 no thanks to Samsung.
Thanks for giving us FREEDOM OF CHOICE.

**UPDATE**
So I un-rooted with SuperSU and Knox is still 0x0. How can I just re-flash my phone back to factory (where/what file do I download) with what software? I can't recall if I deleted any stock apps. I just want it 100% back to factory out-of-the-box.
Thanks in advance!
*old info for reference*
Hi there,
I'm sure I've missed it but I just want to be 100% sure so I apologize if this has (probably) been asked 100 times.
I rooted my Galaxy Note 3 Verizon with Towelroot as soon as it was released. It worked great and knox is still 0x0. I need to do a warranty replacement on my device due to a faulty charging port and need to remove my root access.
Info:
Model: SM-N900V
Hardware Version: N900V.07
Android Version 4.4.2
Knox status: 0x0
No ROMs have been added. Just added root access to stop some apps from running.
What is the proper way to remove root access without tripping Knox?
Probably better safe to just do a full on reset. I found a guide but I'm prevented from posting links... But it involves running Odin and reflashing the default firmware. would this be the correct way to reset/unroot and not trip Knox?
I would like to unroot and just do a full 100% reset as if it was just being pulled out of the box without of course tripping knox. In searching, someone said to just use Samsung Kies software: "under the firmware upgrade menu. It will fully wipe the phone and return it to stock." Is this a correct method?
Thanks!
-edit-
Also just found this on kingoapp:
"How does this KNOX Counter work?
Under what circumstances will KNOX Counter be flagged or tripped?
The KNOX Counter WILL NOT be flagged or tripped when using Samsung Kies or Odin to flash a stock ROM."
Seems like I'm answering my own question. So is Samsung Kies the best route? Does the above statement apply even if you're already rooted?
In superuser setting, there is a menu 'full unroot', use that.

Hi, thanks for the reply. I never could get superuser setup and working, main reason for root was to freeze/remove some stock apps.

Knox will not trip as long you doesn't flash custom recovery or kernel or custom Rom.
Warning:
Factory reset using stock recovery will wipe your internal storage.
Backup all your file in Internal storage first.
Software needed to flash stock rom,
I use Odin V3.09
Firmware = download at sammobile website.
Hello,
I've was forced to create a post about that because there is almost nothing of use that can be found about that phone in the internet.
I need to know how to check the bootloader status on this device so i can safely root it, and if there are any working ROMs. I've found out that it is possible to install 9505 roms on that phone, however the touch and other crucial features do not work while using them.
Cheers, Paweł.
Thanks in advance, i appreciate Your help!
Go into download mode and if you see Knox warranty void you have new bootloader.this has nothing hover to do with safe root or not.you can still however root the device.but counter will be tripped if flashing custom recovery and kernel.

Oh thanks! :good: I will do so. But about that safe root. I wanted to use the CF Auto Root for that and it was said there that if the device has a locked bootloader it will brick if i'll try to unlock the root access.
Should i try another way to root my device or give it a try and see what happens if i'll root it using cf auto root. I know that almost none or all ways to root the device are not safe, but following some of them have higher chances of success than others that's what i meant by safe root.

I think you have misunderstood or misread.or users haven't understand that root is still possible. It isn't locked in any way. The bootloader still let's you flash custom kernels etc.
Rooting with cf root shouldn't and has never bricked your phone on newer recoveries. The bootloader isn't locked in the way of flashing in Odin you can still flash custom kernels and recoveries but it will trip the Knox counter.
However: tripping Knox will cause you being unable to use Knox apps from Samsung and might void your warranty.
Users have told different reports about them being tripped and got warranty and some haven't. I'm not sure if this lies in 3rd party repair centers repairing the phone even if it's tripped. I'm sure Samsung service center is against it.
I'd be 100% sure that my phone carrier would repair it no matter the status since it doesn't go trough Samsung service at first.
However to gain root you should try towelroot it's a one click apk and it won't trip Knox unless you flash a custom kernel or recovery.
Hello , I would like to put my flash counter to 0 with triangle away, I have an S4 i9505 with CM12, but the problem is that it flash the kernel, but never restarts with options to reset, I have to manually restart the it boot normally, I do not understand ..; HELP
Hello,
Our device doesn't have flash counter. That's the Knox warranty void flag, once becomes 0x1 can't return to 0x0

The famous AntaresOne that meets me. It's an honor. Knowing that I have your rom . Thank you, but I do not understand, triangle away is supposed to furnish the counter to 0? But it's not happening, yet s4 is compatible. I read everywhere that it is possible to reset the flag to Knox warranty void 0x0; I do not understand Sorry for my english
Some versions of Android available on the S4 had a bootloader that did not utilize the Knox security software. The devices with this bootloader had a counter that would show how often the device's firmware was flashed. This is the flash counter that Triangle Away refers to, and it could be reset with that app. When the new bootloader with Knox was included, the flash counter was removed. In its place was a new counter, what we call the "Knox flag". On devices where the firmware has not been altered, it would read "0x0". Devices that have a custom kernel, recovery, or ROM installed would have this new counter change to "0x1".
Unlike the earlier flash counter, the Knox flag cannot be reset by any software available to us once it has changed to "0x1". This means Triangle Away is useless if Knox is involved.

Your explanation is very clear! Thank you, you believe that one day this kind of software exist? There to be a way to with what we do today, right?
The Knox flag is an "E-fuse", located within the CPU. One person on the forum here claimed that his Knox flag was reset, but the reality is that he more than likely had his motherboard replaced. If I were Samsung that's what I would have done. Regardless, the only way to restore the Knox flag to 0x0 would be to somehow rewrite the bootloader so that the flag pointed to a different E-fuse than the one that was tripped. In short, that's not happening.

I didn't explain about flash counter (on the pre-Knox bootloader) since was already clear that with you Triangle Away didn't have success (supposed that you have root otherwise you can't use at all that app, this can only mean that you are on Knox bootloader)
Like the other user said, once we had a bootloader with flash counter that was removed on the Knox one. Until today, nobody had success into resetting it due to the eFuse used inside the SoC (once it is blown, its value can't change anymore).
A impossible (because on top of the SoC there's another IC) operation would be to phisically swap the SoC (with non-blown eFuse) from another motherboard to the one with Knox 0x1
Recompiling the bootloader (removing the fuse check) may be a good option, but Samsung doesn't give bootloader source code.

Clearly you didn't bother reading the thread. Resetting the Knox flag cannot be done.
Is there any similar app that would do the same as Knox?

I don't think you quite understood my question... wasn't talking about Triangle Away.. i knwo and understant it is useless as the counter is eFuse wise.
I was asking if there is a replacement for the Knox program - as I am among the ones with burned eFuse.
Thanks
If I misread your question, it's likely because no one has ever asked that question before. In answer however, as far as I know, there is nothing to replace Knox.
