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:

guys,
My I9505 has a hardware problem: the VOL DOWN is unresponsive.
That's a nasty problem, because rebooting the phone gives a lot of problems (warnings about a custom rom, and then nothing works anymore)
So I'd like to return it, but have to restore the phone for warranty.
I managed to flash latest stock MH8.
Here are my questions:
1. before, I've flashed autoroot - does that make the flashcounter go up?
2. before, I've flashed philz recovery - does that make the flashcounter go up?
3. I've flashed the new stock firmware, but still see a clockworkmod folder. can I safely remove that?
4. are there other folders I've to remove to NOT void my warranty?
5. is it necessary/safe to use triangle away on MH8 with the new bootloader?
thanks for any insights!

Be VERY VERY careful if you're running the new knox firmware that you don't trip the eFuse and change KNOX Warranty void status.
If you have flashed stock firmware MH8 in Odin I would simply do a factory reset in the STOCK recovery and wipe everything that way and send to repair centre.
Do not flash ANYTHING custom or otherwise, even older Stock firmware in Odin.
If you do you will trip the eFuse, your KNOX warranty status will change and you'll be f***ed mate.

Thanks, that's very good advice. will keep it in mind.
Do you know the answer to my questions about the flashcounter going up by flashing recoveries in stead of custom roms?
thanks,

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?

Hi, i rooted my phone and now want to make it official again, i still was using the stock rom on my phone, in su i done a unroot but phone still shows as custom.
can anyone help?

If you have a custom recovery, flashing a stock recovery may help. However, I personally recommend flashing a stock ROM through Odin. This will change the status to official, but keep in mind it will not touch the Knox flag if set to 0x1. There is no way to reset the Knox flag, so don't ask.
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 ?

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
so a family member asked me to downgrade his samsung galaxy s5 from android 6.0.1 to the previous version.
i've googled it a bit but only found ways where you either lose your data or need root and he won't let me root his phone.
is it still possible and could someone either explain or link me how to do this?
thnx
Backup photos and videos then downgrade via odin but i am not sure if knox will trip and make wipe to dont get bootloop
Backup using Smart Switch
Downgrade by flashing the ROM you want over the top with ODIN
Got a feeling you'll get a load of FCs / errors on boot with MM apps trying to run on LP, if yes, factory reset from recovery and restore with smart switch
It's won't trip KNOX, that's only tripped by flashing custom

Hi there! I just this post of your's that perfectly fits for my objective.
Is it really possible to downgrade From official stock Marshmallow 6.0.1 to official stock kitkat 4.4.2 without tripping knox? Also does the bootloader will allow you to downgrade?
Just saw this forum and he said that secure bootloader will block any downgrade
"If on Marshmallow 6.0.1 you will probably not be able to downgrade.
Odin will fail at s.boot - the secure bootloader that will block the downgrade."
