[Q] Possible to install a custom recovery WITHOUT root?

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?

[Q] Help, I'm 15 and want to unroot and restore to factory settings

Hi, i have note 3 sm n9005 or something and rooted my phone for some stupid reason, its still on stock the only thing that i think happened was i have supersu, i paniced and factory reset, now supersu has a error thing with something to do with binary settings or something. All i want to do it fully reset my phone, if its any help im british with EE... does flashing supersu trip knox counter? Am i actually rooted for if i were to flash stock? Will that trip it? Iv knly had phone few months and im scared... if i flash stock can i then update legally coz i cant update because the device is modified? I used odin... can someone help please, i know nothing and yes, i should look into what im doing more before hand. Can you explain everything and what to do please? Every little thing, please and without tripping knox and as if it was out the box new. Please
Firstly, flashing SuperSU trips KNOX. In the first place, to install SuperSU you need a custom recovery which would ALSO trip KNOX. Flashing back to stock unroots your phone too.
If you are convinced that you have not tripped KNOX, just re flash your phone back to stock with ODIN.

Flashing stock will get rid of SuperSU and root but you cannot reset KNOX. It is permanently 0x1 and will always be.

What about the fact i factory reset? Is it still rooted to flash stock? And doesnt it have to be a unrooted stocked rather than flashing rooted stock? And where do i got stock and do i need to unzip files and stuff?

Reboot in download mode I. E. Volume down+home+power, check the knox counter if it's 0x1 then it has already been tripped and you have been set free ?? and if it's 0x0 you are still locked in a cage.
Report back with what you see.

I know i have done something coz when i want to update it says this device has been modified. But i havent flashed any roms so surely knox should be 0x0 and flashing stock keeps it 0x0 doesnt it?

Yes, if your Knox is still 0x0, flashing stock keeps it 0x0.
Use Phone INFO ★Samsung★ app to check for the Knox Warranty Void status (in the GENERAL INFO section).

[Q] S4 GT-I9505 Root / Knox / PhilZ recovery

Deleted
user2k10 said:
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.

So if any custom recovery will automatically void my warranty (trip knox) how do I do a full backup (nandroid backup) that I can restore later?
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.

Root for my device? Disabling Knox?

I want to root my edge +
Can i root it without worry about the knox?
Is there a way to disable the knox?
Can you put here a link of how to do a root? Is there an app that will do it? Im affraid of demaging the device..
Here is my device details:
Hi there,
Follow this guide to the letter http://forum.xda-developers.com/s6-...-to-rooting-flashing-custom-recovery-t3200324
You WILL TRIP KNOX and, currently, there is no workaround. Even if you flash a stock ROM with Odin, KNOX Warranty void WILL BE = 1.
You will loose samsung pay and most apps that check for root, like snapchat.

Stock ROM pre-rooted?

Hi to everyone, I have a galaxy A5(2016) A510F and I want to root it but this will trip knox so I want to ask if we root a stock rom and flash it via odin does this detect root and trip knox ? (we will modify the system.img that we find in.tar file)
It probably won't trigger KNOX, but root access would be unstable, at best. Try using KingRoot instead - if it works on your device, it will root it and keep the KNOX counter the same, and if it doesn't, it'll just tell you that it can't root your phone.
I don't want try it because my phone it's new so can someone try it and post the result ? Maybe someone that have already trigger knox, this don't want to be a problem for him/her
EDIT: I think Kingroot don't work http://forum.xda-developers.com/sam...ment/galaxy-a5-2016-success-kingroot-t3400564

I tried king root, but after reebooting my phone was unrooted. I suggest you to flash cf autoroot because, yes, it trips knox counter, but If u soft-brick your device in any way, you can always solve it using odin and flashing stock firmware/PIT...
They are two different things, maybe you are confused because it doesn't mean that if you flash cf autoroot and soft-brick your devices you can unbrick it just flashing stock rom, yes this is true but you can unbrick you phone in anytime without having cf autoroot!
I didn't mean that, i know odin doesn't request root permission, I said that if he flashes cf autoroot and he soft-bricks his device ( I know it's almost impossible ) he will resolve the problem by flashing stock formware (or a custom ROM after wiped cache, dalvik, data and system)
Unfortunately not possible to pre-root a stock Samsung 5.1.1 or 6.0 rom and preserve knox. It will boot loop your device. Selinux will block root and prevent the device from booting unless the boot.img is patched to remove the selinux root restriction.
However patching the boot.img trips knox, catch 22 situation.
Keep hoping for kingroot or Kingoroot if you want to preserve the knox counter.
Thanks for the reply
Can anyone try this http://www.samsungsfour.com/tutorials/how-to-root-all-samsung-galaxy-smartphones-without-pc.html ? I don't want to trip my knox!
If it works it wont trip knox as it doesn't touch the binaries.
Unfortunatelly, I can't try because i've already tripped the knox
