So, i got tired of waiting a port or something like Towelroot for the exynos variant of the S5 and, before i start rooting the phone, i'd like to clear some questions:
1 - Towelroot really doesn't work on 900h and there's no other option besides CF, right?
2 - I live in Brazil, but the phone was bought at one Bestbuy in the US. The warranty will be covered by the store after tripping knox? If not, it means it'll be covered by Samsung in the US (if there's a law for it, like in EU) or in Brazil (couldn't find anything about knox tripping effect in here)?
3 - I think i remember, a long time ago, that there were some problems after rooting and tripping knox, like bricking the fingerprint scanner and loosing other features. Is that a thing, or just an old rumor?
4 - Tripping knox and flashing a knox-free rom blocks you from flashing another rom with knox right? If i only root it and, i don't know, just mess around with Xposed and other root apps, i'll be able to flash the stock rom and install OTAs or i'll need to stick with custom knox-free roms?
1- Yeah. G900H model can only root via CF method.
2- In my country (Bangladesh) tripping knox will not void warrenty, until any damages made by hand..
3- Tripping knox will not create problems with fingerprint or private mode etc. It's an old rumor..
4- Yes. You can always revert back to Stock Rom by flashing your device by a stock firmware.

So they check to see if you've rooted if you break the glass or digitizer? That sucks.

Okay, thanks for clearing that up :good:
And since there were no reports of warranty problems with knox voided phones, i'll assume that rooting is safe in here.

Hey,
I have recently acquired SGS4 in place of my SGS3. I have used to change a rom every week, but now all I would like is a stable, rooted and .
I just discovered all the fuss about Knox and I am even more dissapointed. I really didn't want to buy another Samsung device (Exynos resources, SDS and their horrible overlay) but the offer on it was just insanely good compared to everything else to I took it.
Anyway, below are my current bootloader/firmware information:
http://i.imgur.com/G5pThnv.png
http://i.imgur.com/sl7M1VC.png
As you can see it is 4.3 from T-Mobile from november.
Now would you be so kind and tell me:
Can I root and modify my rom and bootloader on any custom without loosing my warranty?
If not, can I root and change the rom to the google edition?
If nope again, hopefuly I can at least use root with one of the latest Samsung roms? (without T-Mobile bloatware)
You live in the EU. That means that even if Samsung doesn't want to fix your device because you tripped Knox (unlikely that they won't fix it), the store you bought it from still has to fix it even with Knox tripped. That is consumer law which should also apply in Poland.
You can only root without tripping Knox.
You can not flash a recovery without tripping Knox, thus you cannot flash custom roms without tripping it.
So just root and flash the rom you want. You can even skip the part of rooting and just flash a custom recovery.
There are no downsides if you tripped Knox.
Hello,
I want to flash cyanogenmod or any other custom rom on my Galaxy s4. (1 year old)
I'm too scared to trip my knox and void my warranty if it ever breaks.
Is there any way to install a custom rom without tripping it?
Thanks!
No way to install AOSP rom without tripping knox. However, you can install custom touchwiz rom without tripping knox.
we are in the same boat. My warranty has only three months remaining. I will only trip knox if ktoonsez kernel come for official TW lollipop.

I tripped knox 2 months after purchase.
Chances are low that a brand new device malfunctions. Even so, there are reported cases where people who tripped knox said that they were still able to send the device to be serviced in warranty conditions.
I'm going to try it, I will let you guys know if it worked.
Flashed cyanogenmod, works like a charm.
I have 0x1 but that seems that i still have warranty.

You cannot flash cyanogenmod (or other AOSP roms), but you can flash other Samsung-based custom roms without tripping knox.
The method is quite complex though. Generally you have to downgrade your kernel, root with towelroot, use Mobile Odin Pro to flash a new rom preserving root, update bootloader to have wifi.
The risk of mistakes is quite high.
But if you want to have a deeper look, jump here
As you will see the first step is rooting without tripping knox, which is already a challenge.
Once you achieve that, you will find that root gives you already enough mod opportunities, so you may not feel the need to flash custom roms.

Incorrect. He lives in the Netherlands. Tripping knox never voids your warranty in the Netherlands. Samsung made an official statement about it.
It depends entirely in which country you live. In the EU for example, tripping Knox can never void your consumer rights.

That is awesome. But as far as I know Samsung are not the ones who will handle the warranty, but the store from where you bought it the phone.
I bought mine from DOMO (an electronics store here in my country), which means that they will handle the warranty, not Samsung.
Either way, warranty is void once you temper with the software (rooting and changing roms), it is even stated in the "Warranty will be void if" clause. Unless you change back to stock before sending it in.

Samsung gives warranty to their product. They do that freely. But that's completely separate from your consumer rights.
The store where you bought it from has a legal obligation to fix the phone within a certain period of time. You can even pull the device apart, put it back together and you still have your rights. As longs as the fault is not caused by you. I'm talking about countries within the EU. The warranty void message has absolutely zero consequences.
Compare it with a pc. You can reinstall Windows, install a different Windows version, install Linux and when your motherboard breaks down, it will never void your warranty because you installed different software.
So you basically have two options. You can send it directly to Samsung or send it to the store you bought it from.
In the Netherlands Samsung made an announcement that tripping Knox, flashing your phone will NEVER void your warranty. Even if you manage to brick it, they will fix it free of charge.
Hello,
I am new to samsung and knox and really I am lost with so much information specially because I have a original version.
I have a i9505 without any upgrade, so I still have the Apr 12 kernel with I understand doesn't have knox.
Can I install any custom rom?
Can I then revert back to stock? And to stock without knox?
If I install custom roms in the forum they will upgrade my kernel and knox will be installed?
What is the best approach to continue knox free?
Thanks
Custom roms or GPE roms are your best bet if you want knox free roms.
Better upgrade to the latest software and root, then install a custom rom.
If you want stock without knox, you can install a knox-free (knox has been removed by the dev) touchwiz rom.
Thanks for replying.
If I upgrade the software first it will also upgrade the kernel to a version with knox with I will not be able to remove again. Isn't correct?
If I install a custom rom will it also upgrade my kernel to a version with knox?

1) Yes.
2) Kernel has nothing to do with knox. Knox is in the bootloader and the rom. Custom roms do not upgrade your bootloader.
So what is the advantage of upgrading first?
Isn't best to install a custom rom as is without having knox even close to my phone?
My previous question about returning to stock was if I need to send my phone for repair (I am still on warranty) can I be stock again but remain knox free, after installing a custom rom?
Thanks and sorry for probably so basic questions
Please read this thread and gain knowledge from Chainfire (developer of CF-Auto-root, SuperSU). Many of the questions asked have answer there.
http://forum.xda-developers.com/showthread.php?p=45666586
AFAIK from reading the referenced thread only Knox-apps and libs are removed. That isn't truly Knox-free when bootloader is still holding the Knox features.
Even Chainfire hasn't been able to remove Knox.
Please give example what custom ROM is truly Knox free.

I don't know if any custom rom is knox free.
I am still knox free because I have an old bootloader, and didn't install any update.
It's possible to install a new rom without updating the bootloader?
If I install a CM rom will it install a bootloader with knox? If not, can I later reinstall a samsung rom with a bootloader without knox?

Any version CM/AOSP rom don't include bootloader or modem/non-hlos firmware as @GDReaper reply 2). Most Deodexed TouchWiz (TW-based) usually neither. Mind there can be exceptions for TW-based roms.
CWM or TWRP recovery isn't the same as bootloader hence it don't trip Knox.
I had previously CWM 6051, changed to TWRP 2840 and CM11. Updated to complete Samsung stock 501 lollipop directly from that state using PC Odin 3.07. Recovery back to stock and unrooted in one single Odin flash with preserved state Knox 0x0. Phone is GT-I9295 hardware 95% identical to GT-I9505 (some buttons +screen/camera difference).
Downgrade to Samsung TouchWiz rom with Knox-free bootloader =< MH1 when bootloader is newer (N** =kitkat or O** =lolipop) will trip Knox. Because Knox featured bootloader can't be downgraded without trip 0x1.
Updating to any Samsung TouchWiz rom with bootloader don't trip Knox.
Find version:
ADB or Terminal command: getprop ro.bootloader

OK. I just bought this new thing and am looking for some feedback before I even think about installing custom recoveries, ROMs, APP's, etc.
On GSMArena.com my device is listed as the i9505. Everything matches up except the model version under "About device" where it states it as being the SPH-L720T (Baseband L720TVUJOH2).
Now what I want to know is, is that just carrier branding or is my phone indeed the i9505 and will all of the i9505 stuff work on it? It may seem like a silly question but I just paid $300 for this thing and the last thing I want to do is brick it.
The reason why I am asking all of this is because Samsung seem incapable of releasing a fully functioning or secure ROM (Stage-fright issues, widgets draw crashing on "Touchwiz" UI, etc). The current Android version I am running is "Lollipop" build 5.0.1 (official).
Which brings me to my next question: I noticed that my device has "KNOX" installed. Is there any way to install custom ROMs and/or recoveries without tripping it? I want to try to avoid voiding the warranty if possible.
Also this is an unlocked device so will flashing custom ROMs disable that?
Thanks.
I have an s4 with i9500 on it but i reality its an SPH-720T. You can know for sure in the bootloader
So far I had no problem installing i9505 ROMs like 'Super WizCyan, Albe95 S6, Imperium LL Rom' and i am corrently using Albe95 LolliROM 6.0 and it works fine :good: with the latest SPH-720T carnal (OH1) an the Imperium Karnal works too (v2.6)
It is rooted with CF-Auto-Root for SPH-720 and I have TWRP Recovery instaled

Boot into download mode. What does it say your model is in download mode?
The SPH-L720T is just carrier branding. It should be an I9505.
Installing a custom recovery will trip knox. You will have to stay stock if you don't want to trip knox. But beware, knox doesn't like root. Meaning that you will have random reboots if you root your phone and knox is installed.
I recommend reading your warranty document to see what kind of damages it covers. I read mine and it concluded that my warranty covers excrements. So I tripped knox after the first month.

It says SPH-L720T. But according to GDReaper (and the online specs) it is carrier branding.

Crap, I might have already tripped it installing SuperSU (through Play Store, and that's all it took to root it). Under download mode it says "Knox warranty void 0x1". Does that mean I tripped it?
That said, no random reboots the only issue I have is that I can't access the widgets app draw on Touchwiz UI without an FC (but I use a Nova Launcher anyway), and i9505 stuff should work with mine, right? I am thinking about installing EchoeROM, provided it doesn't have the problems the "official" one does.
Knox default status is 0x0
Any modifications done to the bootloader will make it 0x1 which means knox has been triggered.
Since it is already tripped, you might as well flash a custom recovery.
The SPH-L720T has the same specs as the normal GT-I9505 S4. You can compare them yourself.
It is just a rebranded I9505.
I get that it is just a rebranded version of the GT-i9505 but I had to make absolutely sure. In other threads some are saying they have issues. And since I have "screwed the pooch" and tripped KNOX (unless Chainfire's "Triangle Away" can reset the counter), I might as well start flashing then.
I was just reading over this article on how to deal with KNOX and it doesn't seem to cause any issues for me since I am already rooted via Super SU. Will I have to remove it anyway or can I just go ahead and flash TWRP via Odin (can you recommend any version?) without any issues? And is CF-Auto-Root really necessary? I have some experience with all of this from rooting and flashing my old S3 MINI, KNOX and CF-Auto-Root are the only two I'm not sure about.
Oddly enough, while it does say that KNOX (and KNOX II) is installed I can't find the shortcut as described in the article. This is a refurbished phone so god knows what has been done to it.
Thanks.
CF-Auto-Root is only needed for rooting. Since you are already rooted, you don't need it.
As far as I know, Knox status 0x1 is permanent. It can't be changed back to 0x0. The flash counter is a different thing. It shows how many times a firmware has been flashed on the device. I'm not sure if stock roms cout towards your flash counter.
If you have no issues with Knox and root then there is no reason to remove knox.
You can simply flash twrp from their site. The variant you're looking for is for the Qualcomm S4. I used Odin 1.85 and 3.09 with success in the past.
I have a doubt, i am new to samsung device, and know very less about knox, by rooting will it trip knox counter and void warranty? and is there a way to untrip it and claim the warranty or (unroot the device without any issue by flashing the stock fw via odin) .... (like with sony devices)? can someone explain it to me? Thanks
Rooting may trip or not knox depending the metod you use.Once tripped you cannot revert it,it is forever because you burn a fuse on the mainboard.Flashing a new recovery like TWRP will ALWAYS trip knox.
Rooting it may or may not trip KNOX. Considering that you are posting this question here in the A Series forum, I presume you have one of those devices. I don't think there's any method for our devices to root it without tripping KNOX. Flashing a custom recovery will trip KNOX, as said previously. The only other way is to use CF-Auto-Root, which I haven't actually tried, but I do think that it also trips it.
Which device are you using?
KNOX is like a fuse - once it breaks, there's not any way to reset it. At least not in these devices. Personally, I tripped it (on purpose) the day I got my phone.
Thanks for your replies I am using A5 2016..
I think there is no other way to root this device without triping it?

Hello, maybe its just me, but Im not fully clear about rooting my phone. The thing is that I wouldnt loose my warranty, but Id use my loved root required features, such as viperaudio mod, etc.
So there are some methods already, but I dont know, if there any low effort root, or anything similar exist which not triggers knox counter If this method isnt exists, then is it possible to reset the counter after Ive flashed a custom rom / root?
Flashing an original firmware update with Odin will trigger the counter?
Thanks forwards for your help!

Root will trigger Knox. Some custom ROMs had Knox status set as 0x0 but it still has triggered the Knox fuse in reality. Triggering Knox will make you loose Samsung Pay for lifetime. But if you don't care about your warranty or Samsung pay then you could go ahead. There are thread showing you how to do so.
