Hi!
First time posting on this forum, after installing like 40 custom roms from this site.
I have a question, with the current Knox issue, I would like to know if its ''worth it'' to install the stock google edition rom. I have in the past, as noted before, flashed ALOT of custom firmware's on my old Galaxy S1. Although I didnt care much about warranty issues back then, I do know. And the Knox flag is not making things much easier for me as I cant hide the fact that I flash custom firmware.
So, is the google edition all that good for the S4, and might it be possible that in the future, you can install custom firmware without tripping knox 0x1?
Thanks in advance

Hello everyone. ive been searching these forums for quite a while and can safely conclude that theres no way for me (ATM) to root my note 3 without tripping knox.
i have a N9005 running the NC2 firmware, on 4.4.2
now i want to know is, if i flash a custom recovery and firmware ONLY, without flashing a custom ROM, can i still use KNOX (the app) ?
all i really want is root access, im quite happy with the ROM and performance ATM.
very sorry if this has been asked already, i couldnt find anything about it
thanks everyone

Any attempt to modify/temper the phone should render the Knox invalid thus Knox 0x1 as a flag that no Knox security warranty can be established on such devices.
Rooting is considered an attempt to modify the system.
So simple answer is No....
You root you can't use Knox app...
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:

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.
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.
Hey guys,
I always used custom rom in my life, i was at Xperia Z1 and the stock was very bad... But with S6 i don't feel i need to get a custom, i enjoy a lot the Samsung work on the stock, but after looking the Miui 7, i really thought in flashing the custom rom.
So the question is... I saw that Knox and Samsung Pay will not work after the process, is there a way, later, that I can get back to original and get the Knox and Pay working again? My concern is about the security on Knox and the Pay when i sell the phone in the future, because I don't use this feature...
Thanks a lot if anyone can answer me!
Im no expert on android devices but from what I am heard you have to do a full factory reset to a stock rom and samsung pay will be enable but knox counter will still show that it has been tripped.
Hello,
So recently, I've encountered the same Issue I've been having for a long time with any sort of Samsung device - performance. I find my device annoyingly slow. A factory reset fixes this but then the phone bogs down.
I've decided to look into potentially flashing a custom rom to see if they're far more optimised than the stock rom. The problem is, I'm a warranty freak. I like to keep my warranty intact and modify the device later on once the warranty has gone. Obviously, the Knox flag is a thing and I don't want to trip it.
When I had my One Plus 3, I had none of this and rooting/custom roms didn't bother me as it was covered in the warranty - this is a big no no with Samsung.
I'm not so much wanting to change the kernel or the bootloader or use TWRP - just install a new custom rom to hopefully get some performance gains and maybe root too.
TL;DR Is there a viable method to installing a custom rom without tripping Knox?
I am precisly on the same situation as you are

If you have a exynos version then its impossible this moment to have a custom rom without having twrp, which in turn will trip Knox and may effect warranty depending what currently in

Dang it, I do have the Exynos version.
So is there an exploit only applicable to the SD variant?

Yep, the kind-of exploit is only on SD variant.
Although, it can be said that the exploit isn't that good as well, since you will be unable to flash custom ROM (only debloats etc IIRC).
So, they are unable to flash cutom kernel etc.
hi , what about installing custom rom with heimdall? no need for root, no need for twrp. will this triggger knox as well? does exynos/snapdragon matter in this scenario?
hey,
heimdall is only an alternative to odin, anything non samsung trips knox
Is there any way to flash an official rom without rooting to replace my actual one from my carrier? or just a way to at least change the boot screen logo?
