Hi,
I would like to know if there is any known way at the moment to get a rooted kitkat 4.4.2 firmware without tripping knox. I'm momentarily running MKE 4.3, German csc I think. I'm aware of saferoot for this firmware, but I would like to know if there's something like it for official kitkat, or if it is possible to root my 4.3 and then upgrade via mobile odin and inject root via everroot everroot without tripping knox. If not I'll just update via OTA and root via another method but if it's possible I'd like to keep knox for now

No, uptil now there is no such method developed. Check on Kingo root website whether they ve updated to root 4.4.2 firmware.

Oké, Thanks anyway
I don't really trust kingoroot as I thought that it had spyware installed, just as vroot, but then I heard about saferoot and I I was hoping I could keep root via mobile odin, but too bad. I'll just just root via cf-root then

Towelroot. by geohot
Does not trip the knox counter..but don't expect to use custom recoveries. It is a simple root only.

Thanks! I read about it in the featured articles but I wasn't sure it would work or not. I was just planning to use the root to clean the ROM up a bit to free up some system memory and RAM and make some apps system apps, better backups and fiddle a bit with my storage, and maybe using some modules, do you know if using Xposed trips knox?

Xposed doesn't... but I would be weary of modules that perform bootloader or deep system changes
Titanium Backup.. and use backup app and then remove/disable etc
Just be careful... if the knox counter is v important to you.

It's not that important to me, I just don't want to trip it if I don't have to, if I need to trip it for something I really want to do I don't have a problem with it , it's not like use knox thanks you very much

Actually KNOX is very important for warranty issues. If you dont have warranty then I wouldnt worry about it. If you DO have warranty then do not mess with KNOX-tripping root methods.

Rooting my device
Hello,
I am going to purchase an S4, I9505 and I would like to root the phone, just simply because I want to remove a bloatware apps and gain true control of the device.
My question is - if I follow the instructions in the first 3 posts to letter, how much is the chance to brick the phone? The phone is already on 4.4.2. Do I need to do anything else, or just follow the guide?
I know its a silly question, but I am going to spend some money on the device, and don't want to brick it...
Thank you in advance!

0,0000000001%. It's almost impossible to brick your phone.
Root have stopped working.
I9505, 4.2.2, XXUAMDE.
The phone have been rooted for more than a year.
Yesterday I tried "Wondershare\Dr.Fone for Android" as some smemo have been lost. Im not 100% sure this is why the root was lost.
Today I downloaded CF-Auto-Root-jflte-jfltexx-gti9505.tar.md5 and re-rooted using Odin3.
The process seemed to run fine - but SuperSu cant start - get the "no binary fil installed" error.
What can I do?

Will CF Auto Root work on an S4 (Android 4.4.2) with the baseband version I9505XXUGNJ3? I really can't afford a new phone but I want to root this one so I'm taking as many precautions as possible. Thanks.

I would install a custom recovery and get the root access through this one. Everytime I made that this way, works pretty good. I'm always using philz touch recovery

Hi!
I am willing to root my Galaxy S4 GT-I9505 (brand-Vodafone Italy and running XXUGNJ5 firmware) using CF Auto-Root, in order to flash TWRP and Google Edition ROM on it.
It is not a network-locked smartphone, but just "branded" (it gets some easily uninstallable Vodafone bloatware each time I update it via OTA, however I can use whatever SIM I want in it): is it risky for me to root it using Chainfire Auto-Root?

Rooting I9505G running LRX21P
Hi all,
I tried rooting my I9505G running Lollipop 5.0.0 LRX21P. I used ODIN and CF-Auto-root. SuperSu now wants to update, but the update fails.
I later realized that the CF version I used was not meant for Lollipop. Thankfully, my device is still working normally.
Any ideas on how to root?
Thanks a ton!

I used to have Towelroot. I unrooted, updated to my most current Android version (4.4.2), and since then Towelroot won't work to reroot (it says I'm not supported). Is this so for all others? Is there a way to properly have Towelroot root my device, or is Odin my only option now?

Christ the writing in this thread, just answer him for crying out loud. @tempest22 you've answered your own question, you updated. Towel root doesn't work on the newest firmware, downgrade using Odin to an earlier build then use towel root, use neatroms method to install a recovery and flash a ROM , you'll need to use mobile Odin to flash the modem and bootloader, or you may even be able to do it via recovery if you're on a high enough ROM version, there are other ways to root and install a custom rom. If its just root access you need then downgrade then use towel root..always use a method which retains your Knox 0x0 status.

Thank you so much man, seriously. I really just need root access, so if Towelroot doesn't work anymore I guess I'll just use Odin knowing it will trip Knox. Apart from voiding the warranty it doesn't do anything else right? Any reason to keep Knox? I'd rather keep the most recent firmware, so no downgrade for me.
I don't think flashing a ROM via odin makes you lose your warranty, flashing a custom recovery would, bootloader, modem. But not the entire official TAR file. So you won't have anything to worry about. If it were me id do everything I can to retain my warranty, chances are Knox will never be fixed, so if you trip it then it'll stay that way. There is a guide once you're rooted in neat ROMs thread, its straight forward, just download everything you need, get Odin ready and follow the guide. Should be a walk in the park.
Good luck m8

Not disregarding other replies " But", if your not concerned about warranty, and your work doesn't require your phone to have Knox security enabled, Root and flash to your hearts content. Again.... If warranty, is Not a concern, go for it, because trying to maintain Knox 0x0, makes things more complicated than they need to be, nor do you get to try all options at your disposal , and really if you weren't a little bit of a risk taker you would not even know what XDA does.(Odin away, lol) Again just my opinion and if it offends, disregard.

I have a Samsung Galaxy S5 SM-G900FD running 6.0.1 I'm having issues rooting this phone after the latest patch update because before the latest patch update I had used CF-Auto Root with no issues but now I use it now and try to root my phone it just bricks my phone and I wants to root my phone I'm lost without root I can't do nothing I'm bored and I wants to know what's the best way I can root it since there's not many custom roms for this phone... any help is good...
Thanks

Have you thought about installing LineageOS. It supports the SM-G900FD officially.
https://forum.xda-developers.com/ga...m-cyanogenmod-14-0-galaxy-s5-android-t3476433
TWRP recovery you can find at their official website page searching for klteduos. The current version 3.1 should be fine.
Then you could just use LineageOS' SU add-on for root (choose the addonsu-arm-signed.zip)
All at your own risk & good luck

ive restored my phone with Odin so many times, i couldnt even begin to estimate what that number is. The reason i say that is because in having had restored so many times, ive never had to run CF Autoroot. Ive only ever flashed the tar.md5 firmware then twrp 3.0.2 and boot into twrp and select reboot. Twrp then asks you if you want to change the system from read only to r/w. After that, i just install whatever ROM i want and never have an issue.
Hello to all.
I would like your kind advices and opinion on the following matter.
I have a stock s7edge, exynos variant (G935F).
I still have one year of warranty.
After the latest security updates and the fact that I can no longer install S8 apps, it got me thinking about rooting the phone.
I am fairly experienced in rooting phones and installing roms. As a matter of fact, all my previous phones are now rooted and updated to 7.1.2
My question is the following:
I do not want to install a new rom. I am happy with the stock one (at least for now ). I just want to root the phone in order to be able to have access to the system files and replace the apks etc.
Is it worth it?
If yes, how can I root the phone? (any guide with recovery files included etc?)
If I root the phone, what things will I miss and not be able to do? (Do I just lose KNOX and Samsung Pay?)
If I want to go back to unrooted state, is it easy, and how can I do it? (any guide with stock recovery included etc?)
Your kind assistance and opinions will be very much appreciated.
Thank you.

Mate wrong thread.
Yes, sorry about that. A big thanx to the devs for moving it to the right thread.
So, I made a research and I believe that the best way to root my s7 edge is using Odin, then flashing the latest twrp recovery (3.1.1-0), and then by entering the recovery, to flash the latest SuperSU zip (v.2.82).
Do you agree? Or is it better to use Odin and then flash the CF-AutoRoot??
Also, if I want to un-root the phone, do I just have to flash via odin all the stock firmware files (CP, CSC, BL etc?). Will that also bring back the stock recovery and delete twrp?
Also, will the KNOX counter be triggered even if I unroot and return back to stock using the above method?
Final question is what will I miss if I root the phone? I suppose KNOX and Samsung Pay. Will everything else work as normal? Will I have any problem with the camera's performance?
I thank you very much in advance for your assistance.

Hi
There is a guide here - http://www.droidviews.com/install-twrp-root-galaxy-s7-and-s7-edge-on-nougat-g935fxxu1dplt/
make sure you follow this guide EXACTLY
This is different from other phones!
The only thing you will miss is Knox and Samsung Pay correct everything else will work along with Magisk (hides root from apps such as AndroidPay/banking apps).
If you were to install a custom rom i suggest Superstock (current v2.8) As you can probably tell from the name its an improved stock with battery tweaks/camera tweaks etc
Yes when you flash TWRP KNOX is tripped and there is no going back what so ever even if you flash stock firmware and remove root knox will still be tripped so wave goodbye to knox.
if you did want to go back to normal yes just flash official stock firmware with odin this will remove root and twrp.
(knox will still be tripped though)
p.s you could skip supersu install if you are going to root via magisk instead
if you are unfamiliar with magisk etc i highly reccomend just installing a custom rom (such as the one i mentioned earlier) which comes with magisk already installed

First of all thank you so much for your kind reply, contents of which are noted.
To be honest, if I will flash a new rom, my first choise would be a full s8 port rom, like Konghloi's.
The only thing that worries me is what you said about KNOX not reseting even if I unroot and return to stock. I don't really care about the app itself (I think that even samsung will stop its development in order to propmote "secure folder". I am more concerned that I will lose my warranty since the dealers will know fore sure that the phone has been rooted at some point in the past.

understood, having personally tried all the s8 ports already i reccommend ambasadii's S8 Port (Konghloi is a great Dev but past experiance the ROM's are infested with bugs) I'm currently dual-booting Roms and have ambasadii's as my secondary ROM
About the warranty... if you read the fine print samsungs warranty isn't worth a great deal. it will only cover you for an electrical or mechanical fault that is common with the device. (which if your savvy enough you can fix yourself anyway) it wont cover you for any accidental damage drops/water/cracks etc...
Also you can still take your device to an other dealer to fix your phone for you, they don't care what you've done to it (with payment ofc) just not Samsung.
you really have to weigh up both options
personally i think the chances of device failure is slim and easier/quicker to fix as long as its not an expensive fix like the LCD breaking (which if you dropped it and it broke your not covered anyway)
and the pros of rooting and custom roms heavily outweigh the cons of loosing knox and voiding warranty.

@EasyAndroidPro I would like your opinion for the following matter.
I came across this video on youtube: https://www.youtube.com/watch?v=HUoVKH2zp3g
As you will see in the end of the video (at about 8:15), the guy who unrooted his s7 edge usin Odin, says (and shows) that the "warranty void : 0".
What figures...?

Didn't have chance to watch the whole video just skipped through bits but all he did was flash stock firmware... this will not reset your Knox counter and not give you warranty . He probably did not even root his phone lol all he did was update it. Also I think there is a way to root without tripping Knox but as soon as you flash twrp or custom Rom Knox is triggered.
It will unroot your phone but it will not get your warranty back once it has been voided. Knox is an e-fuse once you break it there's no going back unless you replace hardware
Edit: Here is some info from Wikipedia:https://en.m.wikipedia.org/wiki/Samsung_Knox
