Hi,
Tried to google it, but seems i just can find howtoos on installing custom recovery if i root the phone.
However before i root the phone (since its a work phone) i would like to make a nandroid backup of it just incase it needs service sometime in the future. And therefor have a NON rooted image of it.
So my question is: Is it possible to install a custom recovery to make a nandroid of the S5 without rooting it and voiding the warranty?

First read this: http://forum.xda-developers.com/showthread.php?t=2313072
Second If I'm sure you will not void your warranty but MAYBE you will have in download mode Knox Flag 0x1 or something like this and Custom binary 1... BUT MAYBE I'M NOT COMPLETELY SURE
Install custom recovery, kernel, ROM etc. sure trip Knox to 0x1. Unfortnately reset doesn´t exist.
Only towelroot doesn´t trip knox.
Is it possible to undo towelroot again without a nandroid?

Hello everyone,
I am newbie and I want to root my Samsung S4 I9500, current on 4.4.2, I9500DDUFN4, India.
I have some question that I want ti clear before going for this new world of rooting.
1. How to unroot again, if I want to revert?
2. What is this knox 0? And seen in some of the thread that rooting will increase counter to x1. So how to revert it to 0 again?
3. As after rooting I would try some of the great customer ROMs. so, after unroorting which official firmware to install at first (means 4.3, 4.4.or 4.4.2?
4. Most imp just after rooting I am gona factory reset my phone and want to take full back of the factory version of phone so that can be used in case I want to revert. So how to do that? is that is called as Nandroid backup?
5. Is knox 0 x1 counter voids warranty?
6. Any other precautions and suggestions for your side?
Basically I want to root, factory reset, take backup, install custom roms. And in case of failure or problem I want to revert to factory version with official rom and with all warranty.
So please explain or links can be also given so that I will learn my own.
Sorry for this long questionnaire.
and THANKS in Advance.

Hi there,
1. How to unroot again, if I want to revert?
You can unroot by flashing Stock firmware or SuperSU has an option for this also!
2. What is this knox 0? And seen in some of the thread that rooting will increase counter to x1. So how to revert it to 0 again?
Once you have tripped the knox flag to 0x1 you CANNOT reverse it back to 0x0
3. As after rooting I would try some of the great customer ROMs. so, after unroorting which official firmware to install at first (means 4.3, 4.4.or 4.4.2?
As you have 4.4.2 firmware already you will not be able to downgrade. You will need to insatll the original 4.4.2 firmware your phone came installed with or higher!
4. Most imp just after rooting I am gona factory reset my phone and want to take full back of the factory version of phone so that can be used in case I want to revert. So how to do that? is that is called as Nandroid backup?
Yes....or you can back it up with a custom recovery such as Philz or flash stock firmware!
5. Is knox 0 x1 counter voids warranty?
Not in the EU (as far as I know)
6. Any other precautions and suggestions for your side?
Yes! Alot more reading my friend before you decide to do anything to your phone. If you are going to install custom roms then you will need a custom recovery (this will trip knox flag)
Recovery - Philz (recommended but not the only custom recovery)
Root - CF AutoRoot (not the only method)
KNOX - Here
Stock ROMs - Here (flashable in Odin)
Good Luck :good:
Hi,
When towelroot came out I installed it on my note 3 so I could get root without tripping knox. Last night I installed safestrap to get a custom rom without tripping knox, but when I installed alliance rom on rom slot 1 it somehow also installed the TWRP recovery and tripped knox. So now that my warranty is void anyway I was thinking about
installing another rom, just the normal way.
My question is if I should I unroot my phone first and root it the root de la vega method or can I just install whatever rom or recovery I want with my current settings/configuration? Also when I boot my phone into download mode I still get the custom OS warning, I don't know if that's a problem or should I press continue there?

Since you have tripped knox, no worry anymore on warranty. If you plan to flash new rom, you are always advised to have clean installation, meant to clean everything, else you will experience unnecessary problem. To backup your current setting, download titanium backup to make your apps and setting backup. You need to spend some time to familiarize with TB. It is very handy to help u restore previous rom settings and apps.
You do not need to unroot your current rom.

@Marcel94 :
I have never use safestrap anyway... so I have no idea how it works actually.
But... a clean installation will be good.
Grab latest firmware nd flash through odin, and go to recovery stock and do factory reset.
Then root with cf-autoroot, flash cwm/twrp.
Then flash ur rom.

Thanks for the advise guys! What do you mean with "go to recovery stock"? Will my recovery be stock again if I flash the latest firmware through odin? Nevermind, I already flashed the stock rom and got stock recovery, thanks!
Hello,
I'm using a SGS4 rooted since more than one year and a half (odin, flash a small root bin file if I remember well, flash counter set to 1, no custom recovery and no nandroid backup)
Since I want to implement NFC card emulation now avaliable in android 4.4 in one of my apps, I'd like to update.
I've seen few threads on the subject, and most of them date from a long time (am I late ? ). I'd like to know how I could update normally my actual rom (provided by Orange, precisely I9505XXUAME2), or move to another slightly modified rom like the base rom provided by samsung without all these apps that you can only remove with root.
I don't want to have any data issue I've read about, I don't want to lose my actual apps and their data. (Nandroid backup then restoring apps and their data through nandroid manager?)
Also, if possible i'd like to update without losing my start screen, my parameters, etc... (in the worst case I'd re-set them manually). And finally of course I want to have it rooted at the end of the process.
In fact I want it to be just like if I had done an OTA update, then rooted it.
Also, How to update without setting the Knox counter to 1 ? (My flash counter is set to 1, should I use Triangle Away?)
Is there any simpler way than flashing the new firmware and then importing everything from my old data to the new and reinstalling the changes I made to the system (like avast & such) ?
Also, maybe there exists newest versions of the firmware, but without the new bootloader that has the knox counter ?
Thanks in advance!

1. You can't receive OTA updates if you have rooted your device. You have to flash the firmwares via ODIN.
2. You don't need wipe nothing if you flash new stock firmware. Instructions: Flash new firmware (if you don't have wifi flash it one time more), root it again then and you're done. Your data don't have to be affected (maybe you only have to reinstall some app if the data/cache was moved to the SDCARD).
3. Flashing one new stock firmware don't modify KNOX. You actived KNOX rooting your device or flashing one custom recovery. Knox: 0x1 can't be reset. Triangle away only reset the flash counter.
Thanks for your fast answer !
So, flashing a firmware doesn't impact the data.
Updating via Kies sets the Knox counter. Updating via odin doesn't ? Don't I have to do any sort of un-root before updating ?
Is there anything specific I should know about root ? Because I don't want to flash a firmware that I won't be able to root without setting the knox counter.
Also I think that since we can't revert the bootloader update, maybe i'd better not update that bootloader so that I can update future versions and root them without setting knox counter, by installing a knox-free rom even before a knox-free root is released...
Where can I find these roms?

1. Updating via ODIN or Kies don't set the KNOX counter. Downgrading YES.
2. Root dissapear if you flash new update via ODIN.
3. You can flash latest firmware and root them without KNOX. Take a look for the method: HERE.
Thanks for the answer again!
Howerver I still have 3 questions because I like to understand what I'm doing :
1. I understand the two terms ROM (OS of the phone) and bootloader (after a certain update, it adds the knox counter, and you can't downgrade it, and it also prevents towelroot from working). What is the called "kernel" ?
2. Up to exactly what version of the bootloader/rom does towelroot work ?
3. What is the difference between "knox-free" and "knox counter 0"? At the end of the method, will I have the new bootloader with a knox counter set to 0, or the old bootloader ?

1. Take a look: HERE.
2. Nobody know it.
3. - KNOX free: This therm is used for the custom ROMS normally. This mean that flashing this ROM dont touch the KNOX counter.
- KNOX counter: You still having your device in warranty if you have KNOX:0x0. You void your warranty if you have KNOX:0x1 in DOWNLOAD MODE.
So it means I'll still have the new bootloader ?
For those who may come to read this article and don't want to watch a video, I've found an article explaining what kernels are. http://m.androidcentral.com/android-z-what-kernel

Hello, I have a Samsung Galaxy S4 GT-I9505 KOT49H I9505XXUGNK4 running Android 4.4.2
Currently Knox status is 0x0
I have read many threads here on XDA but have not found the answer I'm looking for.
Is it possible to install a custom recovery such as PhilZ recovery and keep Knox at 0x0?
I have read that using chainfires auto-root package will trip knox, so is the only way to root is using TowelRoot?
Is TowelRoot still valid for this version of the firmware KOT49H I9505XXUGNK4?
If TowelRoot works on this firmware, is it correct that I should then remove all knox apps and then install SuperSu from the playstore?
Thanks!

1. No. Custom Recovery will void automatically your warranty: KNOX 0x1.
2. Towelroot don't works with all firmwares. But you can try this other method for root your device without void your warranty: HERE..
3. No. I think only till GNF1.
4. You can remove the bloatware and KNOX app being rooted: HERE. Your device don't gonna be rooted only downloading SuperSU of the playstore. Follow the step 2.

I know I could install the online nandroid backup app but I if my phone boot loops, I would not be able to install it.
What do other people do, is everybody not concerned about the knox flag?

1. One way to backup your things without trip knox is:
- Copy all your internal data on your pc (photos, music, videos, important data). Make this one time for month. You can copy every folder for be sure to your pc too ( I do this).
- Make a backup of your EFS/IMEI (very important) keeping it on your pc or External SDCard: HERE. EFS/IMEI is the identification code of your device. You can lose it sometimes only flashing via ODIN a NEW UPDATE.
2. KNOX isn't important in some countries coz maybe you get your device to one service center and they fix your phone anyway. Depend where you live: you will be out of warranty or no, simply. The people that want "play" (apply mods, flash custom roms, custom recoveries) with their devices don't care about KNOX anymore.

I tripped knox 3 months after I bought my device brand new. And many other people have done so.
Somebody said that if you live in the EU and trip knox, this will not void any of your consumer rights.
He also said that: Samsung stated that if you live in the Netherlands, tripping knox will never void your warranty.
Hi, I accidently rooted and installed cwm on my galaxy s4 gt i9-505, without disabling knox, and now I want to go back to the orginal samsung bootloader, (I don't not want to know how to get the stock firmware), I want to unroot and restore the bootloader, really need help asap, would be apperiated thanks.
Update: I'm on Android L 5.0.1, and installed cwm before rooting which was a silly mistake, because knox then countered that, and it's conflicting root problems when I tryed to root afterwards, but now I just want to go back to the Samsung bootloader, root issue fix but still don't know how to fix bootloader.
Not sure what is there to fix - if phone boots correctly it is good.
If you try to revert back to knox 0x0 I'm afraid it is not possible.
Flashing root and cwm doesn't replace your bootloader
How do you accidentally flash root and a customised recovery?

You are really mixing things up.
A custom recovery has nothing to do with Knox. A custom recovery gives no problems with Knox. It's impossible.
You are on the samsung bootloader. You cannot change it to a custom (there isn't even any).
If you want root just flash cf auto root and then delete knox. That's all.
