[ROOT] Saferoot: VZW SCH-I435 (& others), no Kingo, will NOT trip KNOX (0x0)

Disclaimer: You are fully responsible for anything you do to your phone. This is the safest method possible but there are always risks involved. If you brick your phone, or have any otherwise negative effects no one here is at fault.
I am not a developer and can take no credit for this (and consequently cannot provide support for this)! All credit and thanks go to @k1mu for this method.
For those of you who want root access to your phone and do not want to use Kingo (root without Kingo) here is a safe method. The best part is if it doesn't work there is no harm done to your phone, it simply will not root. This will provide root on the stock software and DOES NOT trip the KNOX flag (your KNOX flag will remain 0x0). The way to trip the KNOX flag is by changing the kernel or bootloader/recovery and this does neither. It may change the System Status to "Custom" (this can be seen in Download Mode or in the phone's menu under Settings->About Phone->Status->Device Status) but there are ways to change that, see the details in the original post.
This does not unlock the boot loader, does not install a custom recovery or allow you to load custom ROMs.
@k1mu created this method using an Experia exploit and modifying it for the Galaxy S4 full size, however it works for many other Android devices. I used this to root a Verizon Galaxy S4 Mini SCH-I435 and other people have reported this working for the S3, Note 2, other carrier phones and some non-Samsung devices.
This will provide root access on your phone and install SuperSU. This works with Android 4.3 as well as 4.2.2.
Here's the basic steps to root your S4 Mini (for the full step-by-step visit the thread):
1. Setup USB drivers on your computer.
2. Enable USB debugging on your phone.
3. Enable USB ADB access.
4. Download and unzip the Saferoot.zip
5. Root your phone
6. Click "Thanks" on k1mu's thread for this (yes I added this step ).
If you have questions or run into problems reply to k1mu's thread. He is very helpful and quick to reply.
If you find yourself needing to unroot, visit post #2 in the original thread and follow the steps. You can find SCH-I435 stock firmware and Verizon software in this thread (post #10 & #12). I HAVE NOT TRIED THESE SO USE AT YOUR OWN DISCRETION.

List of devices this is confirmed working for:
Verizon SCH-I435
GT-I9190
GT-I9195 some variants (see post 33)
GT-I8190 (S3 Mini)
Devices this does not work for:
GT-I9195 some variants (see post 23-31)
Let me know if this works for your phone and I'll add it to the list.

What was the value of Knox counter in Download Mode after rooting with this method?

The KNOX flag is 0x0. Your warranty will be intact.
I'll upload a picture as soon as I can take one.

This root technique doesn't touch the Knox Warranty Void flag as it doesn't try to flash anything (kernel, bootloader, etc.)
It does, however, set the "Custom" flag at boot. See post #2 in the original thread for ways to clear that.
It does NOT unlock the bootloader. Don't go off flashing AOSP or CM after you root, as those WILL set the Knox Warranty Void flag.

Here you have it straight from the source!
Interestingly it didn't change the custom flag on the phone I rooted. Download mode shows system status is "Official" and the device status in the menu also still says "Official."

There's tons of other options for GT*'s (flashes, roms, roots). I'd suggest checking them out. The verizon version (SCH*) was the one lacking safe root.

This is fairly new in the Mini world so I'm not sure which ones this method is confirmed for, but it should work for most any of the models. Over in the full size S4 forums it seems the AT&T phones are preventing root but others are having success. I don't see why it wouldn't work on your 9190, but the beauty of it is if it doesn't work there's no harm done. The ADB debugger will simply stop and your phone will remain unrooted, it's worth a shot.
If it does work let me know. I've started a list in post 2 of Minis that have successfully rooted using this method.

There's a root method listed for the 9190 somewhere here in the forums but I believe it trips the KNOX flag and voids warranty. The post doesn't say whether it does or not, but gathering from what others have said in the thread it appears to change the KNOX flag to 0x1.

I'd give it a couple days to adjust to it's new digs. I loaded a new kernel on my S3 which was supposed to improve battery life, day one was terrible but from then on it did in fact improve. I wasn't a believer in letting the phone "settle in"until then.
For curiosity sake, what did you do to unroot? Did it return the custom flag to official if it changed?
Can I count this as confirmed for the I9190?

You can definitely count this as confirmed. I'm not sure if the custom flag has been tripped. Nothing has changed in the About device settings

Just want to mention, I went into odin mode to check my knox status, and there is no mention of knox whatsoever??? i want to make sure my knox status isn't 0x1 but it looks like its gone? i thought knox flag was set by hardware? the eFuse or something

Has anyone tried it with the GT-I9195 model?
And more specific with the I9195XXUBMJ7 firmware, will this method trip knox warranty void?

doubt it man, this method is still new. if anything you could be the one to test, as i did, i do have my warranty at stake, but cant be sure if its void since im not seeing ANY flags, the knox app is still there, but if i go to odin download mode, no knox entries appear.

That is because u don`t have NEW bootloader yet
Just to be sure tell me what u see in *#1234#
U are in luck so to speak u have old firmware that does not contain Knox bootloader only Knox apps that are harmless without bootloader
U can use this guide : when a new firmware comes out Just don`t update with Kies/OTA and u are good to go

Well, u know better what u want from your phone
U can use Kies/OTA and stock rom no root / no different kernel and battery drain for now and hope Samsung will fix it on KitKat ( I did write to them on all channels how to fix it but .... will take a loooong time
Or Odin Stock rom / custom rom + custom kernel + no battery drain
Anyway all this is off topic
Just wanted to let u know u are lucky and can do a thing about Knox Other updated and cry after ^^
Take care mate

so you are saying i am safe from knox warranty void 0x1????

[Q] General inquiry about KNOX and FW types

Hello all,
I searched the forums round and round, and couldn't find my answers so I hope you will be able to help me out.
i'm looking for a new phone and decided I want to go with the S5. that was before i learned about KNOX and it's wonderful ways.
i'm a heavy modder, who will most definitely use a custom recovery and ROM/kernel.
my questions are:
1. would it be possible to flash a custom recovery / rom / kernel / modem despite KNOX being preset?
2. other then getting this 0x1 and voiding my official warranty, are there any other result to this? will something not work?
3. assuming I get an unlocked international phone, is there any need to mess/change my FW? or is that just part of guides for rooting without tripping KNOX ?
Basically, I want to be sure that I could do whatever I want to the phone without getting stuck or turning it unusable because of KNOX. my current phone is a Nexus 4 and it has been heaven. I want to preserve this feeling
thanks for the help guys, appreciate it!

Did you tried Towelroot method for rooting your device? I heard that doesn't trigger knox..

I would imagine my rooting the phone is the least of my worries.
as far as I know - and this is one of my questions - flashing a custom recovery and or rom will 100% trip KNOX.
not that I care, I just need to know if this is true..and my other questions as well
thanks!

A brief answer
If you - as you say "i'm a heavy modder" Samsung phones are not for you

I've heard tales of people having issues flashing modems when knox is triggered. I have not checked that out for myself Joe have I searched any further into the matter.
I plan on breaking knox soon though because screw knox.

This answer really worries me to be honest.
could you elaborate?
I don't really care about KNOX, and as long as I can mod away and jump back and forth between modems/roms/kernels - I don't care for the warranty.
If indeed there is truth in the matter, and modem flashing will become a problem if KNOX is tripped, then this would be a deal breaker for me on this phone.
anyone care to add more info here?

You can, but you will always have problems like network, connection,calls, bugs and so on
Samsung devices do not provide the old pleasure as previously
Knox killed freedom of developers and people who like customizations

I would really appreciate an answer from someone who knows for sure.
does tripping KNOX disables the option to upgrade/downgrade the modem?

No, KNOX tripping is only at the moment a warranty void solution for samsung. its like the flash count flags.
basically if you trip knox. you're already in it. you do what you want

I bought my phone with ANCE firmware and the KNOX was tripped in the first hour by CF-AutoRoot. Now I'm on ANG2, flashed with Odin and the modem is updated correctly.

Exactly, but with full stock image flush (including bootloader). The full stock tar.md5 form sammobile includes the modem/bootloader/rom. I think that the important thing is to have a modem which is compatible with the bootloader (same version). Didn't try to mix different bootloader/modem(baseband) versions.

Tripping KNOX will only disable the feature which allows you to store some data on a encrypted part of the device (Mostly comercial use) when KNOX is tripped any data stored on the 'special' partition is destroyed.
So there are only 2 things that will be affected, your warranty (Not a problem in Europe) and the special partition that I explained earlier.

Root vs. Security

Hi there,
As far as I could read, we now have a stable kernel(arter97) and a deodexed rom for the G928G.
With security in mind, regarding the Edge+, I am starting to feel that if I root my device, I will have a lot more posibilities concerning getting it more secure. For example, I would be able to use a firewall, uninstall default apps and bloatware, just for starters.
Otoh, a rooted device might be less secure if you are not careful... but I read recently that new malware is capable of rooting android so, basically that defeats my entire argument about not rooting it.
From your experience, would I be able to use a rooted device with arter97 kernel and the deodexed ROM above (without bloatware) securely?
In your opinion, what additional steps should I take?
Would I be able to revert to a stock ROM / original state that would enable me to use samsung pay, or rooting is a one way trip?
Are there any additional features that rooting would disable besides samsung pay (I also have a Sony Z3 and rooting it would disable taking high quality pictures with the camera)?
Thanks in advance!

I thought those were tough questions at first, but not that much
Ten days later, I have found an answer for question 3. Right now, afaik there is no way around a tripped Knox and there are no guarantees that it will ever be or in a near future.
I am still looking for ways of getting a more secure platform.
Started thinking about the original idea (ROM and kernel suggested), using a firewall, a VPN and a service like adguard as a local proxy.
Any further ideas?
Thank in advance!

For now it's a one way trip, as it's based on knox, if you trip know you will lose Samsung pay.

You will lose all Knox possibility. Samsung pay, and maybe some other thing. But I don't think you'll lose High Quality pictures.

Ok, so rooting = trip knox = disable (forever) all features that rely on it, like samsung pay.
One last question: let´s say I root it and use it rooted for some time. Will I be able to revert to a default samsung ROM even with KNOX void = 1? Once I get back to a default rom, will it update automatically or that will be broken?

Yes you can go back to a default ROM (ie not custom status) but with knox void by just flashing a stock ROM via Odin - once knox is tripped it is always tripped and you will NOT be able to use Samsung Pay and there is no reset for Knox (Know=1), there are other pay methods that might work and some work when rooted too

If you go on official samsung firmware I think you could have automatic update. I might say I never go back to samsung official rom when I installed custom rom, only when I sold my phone so I don't know if it update after lol.

LOL that´s exactly the reason behind my question... If I sell it some day at least make sure that updates are coming through...

The main reason I haven't rooted the phone is because of Samsung Pay, if you don't plan on utilizing it then by all means root the phone. And yes even if Knox is tripped you can still receive the updates, I have several rooted galaxy devices with Knox tripped and I still receive the updates. On a side note if you update a rooted phone you will most likely loose the root and have to re-root again.

Thank you! I guess the only drawback for me is a practical one. Every new update means that settings won't be preserved. Anyway I think I can live with that.
Sent from my SM-G928G using Tapatalk

Oh... following the procedure to root, I have learned that flashing the ROM is not mandatory. In other words, you flash a custom recovery, arter97´s kernel, install SuperSU and that´s it...
At this stage, will automatic update work?
(of course, I understand that if it does, it would reverse to a non-rooted device and I would have to do it again)...
Does rooting reset / wipe the device to factory settings?

Yes, custom roms are mostly for added features but it is not mandatory.
Automatic Updates should work, and rooting/re-rooting does not wipe your phone.

All things root and Bootloader?

Hi Friends,
Hope you're all having a great new year. So last time I was lurking the S7E forums, we had a leaked Engineering Bootloader that was used to acquire root on all US Snapdragon models, albeit, with a lot performance issues and etc.
I came here to glance as well as all other variant forums for the SD model and now we have Root for every model, with even ROMs being baked like the Echo ROM for Verizon, Sprint, AT&T models, usually the toughest to achieve these things on. I'm trying to read through the forums, but I fear I'm missing the details, that will help me pull the trigger for getting the device or not.
Can one of you very experienced, knowledgeable, and kind members educate me on the latest?
1. Do we have unlocked Bootloader and Root for all US carrier S7Es? How is it done? I use people using Flashfire. So no TWRP?
2. Does this process still trip Knox and render Samsung Pay to never be used again on the device?
3. If I bought the Verizon variant, for example, can I root, unlock Bootloader, and etc, and then return to stock, to return to the store in case I don't like the phone?
4. Xposed Framework working for all models?
Much appreciate your responses, any and all of them in advance! Thanks!

1. There is no unlocked bootloader on any U.S models. Flashfire is what we use to flash ROMs.
2. Knox is not tripped by anything you'll see in these forums. Rooting disables Samsung Pay, but flashing back to stock fixes it.
3. Yes if you root or do anything you can Odin back to stock with a clean slate.
4. Yes

Do we really need another root/bootloader thread?

Thank you very much for your response, bud. One last follow up question: Since all the US variants are rooting based on the ENG Kernel, is there really a benefit of getting one variant over another, for rooting or etc purposes?

Yes, just fine.

Yes it works. Currently using G935UUEU4APL4.

What's the advantage of UFirmware? From what I've read, it has less bloatware but just eats a lot of battery.

It reportedly consumed more battery on rooted devices, unrooted should be fine, though I have had no problem running on it (though I have a fair bit of adjustments applied). The U-Firmware performs better for me and a friend immediately noticed how much smoother his phone performed after switching. Wifi calling still works, though I think you loose VOLTE & vide calling. Less bloat could probably lead to better battery anyways, though to be safe you could always switch to apk1 and wait for Nougat.

On T-Mobile VoLTE still works, but the built-in video calling is absent on the U firmware.

I thought after you tripped Knox by rooting there was no going back, and Samsung Pay is permanently broken. Is that not the case?

Rooting does not trip Knox.

Rooting does trip Knox. Flashing OEM firmware via Odin doesn't. Once you trip Knox, Samsung pay will not work anymore.
To answer OP's question, yes it works. I've been rocking G935U latest firmware on my T-Mobile Variant and works beautifully. I strongly suggest you move to U firmware.

Huh. That's very odd because I've rooted my S7E several times and I'm still 0x0 and I'm not rooted anymore because I like the use of Samsung Pay.
Don't think that what you're saying is accurate.

That's weird that it doesn't trip yours. All the posts I've seen on XDA and everywhere else say it does. Did you go as far as flashing a new recovery? I've tripped mine on my Note 4 before (not doing on my s7e because I still like to play it safe). How did you root yours? If that doesn't trip Knox, then Samsung just had a major mishap on their security. Good for you then. :good:

We can't flash a new recovery because the bootloader is locked.
You're writing in the T-Mobile forum man.
None of our Knox is tripped. We get root through an engineering kernel and flash through Flashfire.
Samsung Pay doesn't work but our Knox is still 0x0.

Pretty sure the only root that trips Knox is CF-Autoroot that you flash through odin, that's only available for the F model and the china snapdragon model.
