On Stock KK , Knox is in 2.0 version !!!!!!! more secure ,more "heavy" !!!!! damned .......... :mad:
[Galaxy S 4 Mini General] halc:
Bad luck

I triggered KNOX while i was installing STOCK Firmware on my phone. I choose the Orange Romania ( ORO ) firmware instead of a ROM firmware.. and, voila'. Knox Triggered.

What are the consequences for rooting etc? Is it possible root on 4.4.2 (odin, OTA from original 4.2.2, towelroot, RootkitV2CF-autoroot)?
[Galaxy S 4 Mini General] Loulou-13:
yes ! yes ....... i know ! it's not a problem ...

It's just impossible to downgrade via Sammobilefirmwares ,and for some people who don't want to root ,it's more heavy system ,and system encrypted :impossible to do some mods...

I have flashed Amestris_Kernel_V2-MK4_AUTO-ROOT_GT-I9192 to root which did not work. Then ROOT_I9192_CWM6_Kernel which worked for my 9192 device ( baseband DDU1BML1). Knox has not triggered.

I have flashed the knox free rom and original firmware with knox and re- rooted.

I am having problems with custom roms.

Roms based on 4.4.2 work well.

4.4.3 and 4.4.4 i get trouble with dual sim.
[Galaxy S 4 Mini General] Flyser:
I am still using a pre-knox 4.2.2 firmware (i9195xxuamh3). Is it possible to modify the official 4.4.2 ROM to not install knox? so I don't get knox bit flipped when I later choose to install a custom rom?

EDIT: okay, I found this http://www.s4miniarchive.com/2013/12/how-to-remove-knox-bootloader-from-new.html

Has anyone tried this with the 4.4.2 rom already? It's supposed to have knox 2.0, so this might make a difference.
[Galaxy S 4 Mini General] gladson1976:
I'm using CarbonRom 4.4.4 on my 9192 (had BML1 firmware) amd I'm not facing any issues with dual sim
[Galaxy S 4 Mini General] kev23m:
Yes noticed most dont have the problem.At a loss whether knox has been actually removed or something else.

Strangely the stable rom based on 4.4.2 works fine.

Not allowed to post links as yet.
[Galaxy S 4 Mini General] gladson1976:
It takes some time to register the networks when you change the subscriptions. it usually takes 20 to 30 seconds for me.

Just go back to the main settings menu and then enter the Multi Sim menu after 30 secs. Should be fine.
[Galaxy S 4 Mini General] kev23m:
Ok , gonna do a fresh install and give it another go. Will let it run thru the day and see.

I restored to the knox free samsung firmware and double checked , no knox files at all. So root and knox free is confirmed.

Update :

Same issue , as soon as data call selected , it searches for network again and changes setting in multi sim. Works perfectly with 1 card disabled.

Update :

Just tried it with another cm11 version released. What is happening is

1) if i disable mobile data for 2nd sim , mobile networks automatically switch off.

2) if i use wifi , once wifi disabled again mobile networks go off

Turning mobile networks on , data is enable for both sims and even though i select any sim in sim manager , it just keeps toggling on its own.

I take it the telephony patch is not working for my device in roms based on 4.4.3 and above. Works with 4.4.2
[Galaxy S 4 Mini General] fburgos:
I have a story that I believe its knox related.

Couple of months ago I broke the screen of my first i9192 knox free phone, then I bought the second one wich came with knox bootloader.

I didnt mod my 2nd. phone because i didn't whant to trip knox and loose warranty, just rooted with saferoot it worked flawlesly all the time in 3g/2g auto, i never got any problems.

By the time cm11 came out i was so happy that i din't care about warranty and triped knox installing latest cwm recovery, flashed cm11 and it worked fine but I had a lot of signal drops while using 3G, but still I move on in 2g mode only I tried every build but still I have signal drops while using 3g mode some times where better than others, but still after some time the phone lost 3g signal, then I get bad quality on calls not connected to the network and no signal at all, but at the time I choose GSM only mode the signal got back and working fine but only in GSM mode, but none of the users of cm11 reported my issue then i thought was my modem tried different ones but with all i got bad quality on calls and network drops if i select 3G mode, even "wcdma auto" or "wcdma only" i end with no signal, no network, bad quality on calls that was fixed using "GMS only"

yesterday I was sugested to try back a stock firmware, the latest blackedition i proceed with the instalation, but my sorprise was that the issue persist, network drops in 3G mode bad quality of calls and not registered on network, then tried my phone with different simcards and all seems to work in 3g but didn't have the time to try them for long time, then its like mine that works for some time then drops, but my simcards were working flawles and connecting 3g signal on other phones then I didn't blame the sims, since they work on other phones.

still sad and pissed off I came home and disassembly the phone and exchange mainboards. the phone booted normaly in the old rom and working fine and connecting to 3G, then I update recovery and install a cm11 to test.

From yesterday untill now my phone has been working flawlesly on cm11 with the old knox free board, then I blame tripping Knox all the problems I had with 3G signal and somehow screwing the modem.

This video is with the Knox 0x1 board and the "bug"

http://youtu.be/s_v5jLVWb44

This video is with the Knox free bootloader board, wcdma works in both sims.

http://youtu.be/SODNFV4U-ao
[Galaxy S 4 Mini General] kev23m:
My case is even stranger. I am now on knox free stock rom , all good no problems. The cm11 stable by sekil based on 4.4.2 works well too. It is only with the roms based on 4.4.3 and 4 that give me trouble with multi sim. If i use 1 card then works really well. The 3g signal is fantastic and it catches on also real fast.

I am left scratching my head how it works with 4.4.2 and not 4.4.3/4

Also like i had said before the knox counter is still 0 x 0 , updating shows processing failed.
[Galaxy S 4 Mini General] kev23m:
I think it is a hardware defect. I flashed original firmware with knox and send it to samsung. They are replacing the mother board. I will get my handset back tomorrow. Hoping that my issue is resolved. Will root and check it tomorrow night itself. My knox flag never triggered.

Knox already on Android 4.2.2?

Hi,

Today I got a new I9195 with firmware I9195XXUBML4 and Android 4.2.2. When I boot into download mode I can see the Knox flag as well as 2 Knox apps in the application manager. Do I already have a secure Knox bootloader which makes it impossible to flash an older firmware for example?

I´m a bit confused because often I only read: 4.2.2 is still good in terms of Knox and >4.2.2 is not.

So,

- is it possible to downgrade the firmware?

- is it possible to root AND install CWM without setting the Knox flag to 0x1?

Installing a custom recovery will always trip Knox!

And there is no need and no point to downgrade anything.

Hi,

Read this topic and you will find all answers that you need. I upgraded my phone last week and was using a Jelly Bean rom, following these topic I upgraded to KK and root my phone whithout voiding my warranty.

You just have to check if you don't have the new bootloader.
[Galaxy S 4 Mini General] fburgos:
I think first enforcing kernel came with Knox, go in download mode (power+home+vol down) if the word Knox appear then you have Knox bootloader.

Best case it should be Knox 0x0 and official status

hello..just got the phone 2 days back..i was on 4.2.2 indian firmware....checked download mode and it said knox 0*0...now i flashed the 4.4.2 firmware downloaded from sammobile via odin and when i recheck knox is gone....!!!!

just said binary and system which changed from official to custom once i rooted it with CF-root method(nothing else was working...saferoot/towelroot etc)..and as i seem to have read that flashing stock rom reverts these back to official...is it true?

and does this mean that my knox firmware phone has been converted to a non-knox one after kit kat upgrade?

please anyone let me know..thanks
[Galaxy S 4 Mini General] rogier666:
Not if your boatloader is old enough. If you boot into download mode and it doesn't say anything about KNOX you can flash anything that doesn't update your bootloader. I'm keeping my good old MH2 version :)
[Galaxy S 4 Mini General] rogier666:
Samsung says it's an eFuse: https://www.samsungknox.com/en/blog...ox-enabled-devices-and-knox-warranty-void-bit
[Galaxy S 4 Mini General] Mac23:
Thanks for clarifying. So every firmware after MH4 is "Knox infected" although it came with Android 4.2.2.

You can find a firmware overview at hand-faq.de where the knox firmware is red marked (unfortunately I am still not allowed to post external links).

But assume you are flashing Kitkat would it be possible to go back to 4.2.2? I read this won't be possible unless you are using a firmware which also has a Knox boot loader like MJ7 to NB3. Am I right?
[Galaxy S 4 Mini General] rogier666:
The bootloader resists downgrading. You could try to flash an old ROM without bootloader:

hi, have an i9192 with UC knox bloody bootloader and tripped 0x1 trying CM11, and now SE is enforcing;

then rooted the phone and got rid of most knox stuff.

is 0x1 locking the bootloader so that flashing (downgrading) is not possible (yet)?
[Galaxy S 4 Mini General] Aronuser:
0x1 is only about warranty and knox stuff which can't be used anymore as written in the OP, downgrading from kitkat stock is possible if you skip flashing the bootloader again.
[Galaxy S 4 Mini General] flapane:
I (unfortunately) have an UB bootloader (4.2 stock ROM) with Knox enabled.

4.4 stock roms have already been released in some countries (ie. Germany).

Is it possible to install the german 4.4 stock ROM on my portuguese no brand i9195, without triggering the eFuse? In other words, does the change of country code (CSC) involve a rooting process?

Thanks

I've installed UAMH2, does not contain knox, and now both kernel lock and warranty void are 0xfffffffc:

Knox trip

Hello, i am new here and i have some questions about knox. My s4's mini battery is draining very bad and i read that a custom rom like cm will give me battery results. I want to ask if it worth to trip knox for installing a custom rom and if i will get better battery.

Thanks and sorry is i am off topic.
[Galaxy S 4 Mini General] t5s:
IMHO it makes more sense to discover the tools which help you determine the apps which cause the drain and how to tame them. From my experience with CM11 on my last phone the problems don't magically dissolve with a new ROM. Actually with my i9195 running on stock ROM I now have more overall stability than before with CM11. The crucial point is to know the tools for analysis and taming. I'm using greenify with the corresponding xposed module and occasionally I'm using Advanced Task Killer to stop everything I don't absolutely need, in cases where I have the impression that something sucks. And I use titanium backup to freeze apps which I absolutely don't need.
[Galaxy S 4 Mini General] skymapper:
On i9195 i have knox kernel 0x0 and knox warranty void 0x1 (in download mode), whereas in boot i have "set warranty bit: kernel) message. This is after i flashed cwm and LP. No functionality glitches so far.

Try f4k's lollipop. I have it on i9195 for some weeks now and, combined with UCNK5 modem i have a nice battery life now. Check that thread as it contains tweaking infos also.

Hello, thanks for your advice. I am thinking of buying an s4 mini on o2 contract and if the bootloader is locked will i be able to unlock it? Or if you cant unlock the knox bootloader can i still flash custom roms?
[Galaxy S 4 Mini General] xpamamadeus:
Samsung does not have locked bootloader.

Knox only show if u void warranty or not.

In my case i buy i9195 and flash custom rom before even know about knox and i woid my warranty.

my device have problems with autoreboot if i use 3g or 4g network and i restore original firmware and send it to service and they tell me that i need to pay if i wanna repair...

Soo be sure your device its 100% ok before u flash custom roms.
[Galaxy S 4 Mini General] wmiki75:
Hi!

I am a new s4 mini user, i just bought an used, unlocked phone from the internet. Without IMEI label on back... in the SW there are imei number.

This is what i know my phone:

Knox Warranty: 0x1

CSB-Config-LSB: 0x30

Bootloader AP SWAEV: 2

Write Protection: Enable

Android: 4.4.2

Kernel: 3.4.0-2659908 dpi@SWDD5809#1 Sat Aug 30 14:01 KST 2014

Build: KOT49H.I9195XXUCNH5

How can i install an other ROM?

I do not like KitKat with SD card restrictions.

Can i install an old 4.2 original firmware? Can i back to 4.2, or an modded 4.2 ROM?

Or what ROM do you suggest, and how can i install it?
[Galaxy S 4 Mini General] 2010radams:
Hello, I am not sure if you can go back to 4.2, there are other threads I think about that. If you just don't like kitkat because of sd restriction you could root the kitkat and then install an app from google play and that patches the rom so you can use the ext sd card.
[Galaxy S 4 Mini General] Aronuser:

[Galaxy S 4 Mini General] wmiki75:
Aron, do you think, this topic: Downgrade Guide?

Are you sure, i use this PIT file (CSB_signed_SERRANOLTE_ONEPIT_OPEN_130523.rar), and this 4 files ROM (I9195XXUBML4-D_BT.zip) to go back 4.2, from 4.4.2 I9195XXUCNH5, with Knox: 0x1?

Somebody said i cant back form 4.4. because 44. Bootloader, locked, the phone. I am afriad, i brick my phone :(
[Galaxy S 4 Mini General] sasank360:
DO NOT USE FILES ON THAT THREAD TO DOWNGRADE TO JB 4.2.2.

You will hard brick your phone. U can use those files if you are on old bootloader and stuck @ bootloop or softbrick.

Not meant for downgrade.

I get softbrcik :(

I try to flash a new ROM with Odin:

TMH-I9195XXUCNK5-20150205223603

But beofre the end of flashing phone says: Invalid ext4 image.

Now i unable to get Download mode, and flash any ROM.

Phone says: Firmware upgrade encountered an issue. Please select recovery mode in KIES and try again.

And i can not find, my original ROM on the internet (KOT49H.I9195XXUCNH5)

What can i do?
[Galaxy S 4 Mini General] 2010radams:
Your original rom should be in the sammobile firmware archives. Unfortunately if you cant get into download mode that is a problem. Have you tried taking your battery out, then press your power button a few times, then reinsert battery and see if you can boot into download mode.
[Galaxy S 4 Mini General] wmiki75:
Thank you, now i can enter to download mode.

I flashed I9195XXUCNK4_I9195YBTCNL3_DBT German ROM, and it works, no ext4 image error!

But there are few german apps, if you know a clean ROM i try to flash it...
[Galaxy S 4 Mini General] marcooleo:
Little confused here I have a i9195 shipped with 4.4.2. I got problems with the phone and needed to flash it because Samsung Kies could not do a emergence recovery, only with a specific code....So i googled and found a page where people were asking for codes...don´t remember if it was a samsung support site. Anyway another site i found was selling unlock codes. So i wonder now since i have triggered the KNOX when i had to flash the original firmware via Odin...how could that happen? Also when i looked in settings i was already a developer and USB-debugging enabled, that´s strange i thought sammobile´s firmware was not modified...? Or am i wrong? Anyway if i do a emergency recovery with a unlock code bought from Samsung or whereever, do i get rid of that KNOX-trigger? When i bought the phone i even took a special insurance that covers almost everything, and now warranty is void propably (i live in Sweden). So what can i do, brick it and then drop it on the floor so the screen brakes and then flush some water in it? Yes that insurance covers "accidents"...;) So if Lollipop ever rolls out for the S4 i wan´t to upgrade. As it is now i can only flash a stock firmware without being able to update, or run a CM12 which i do now. Is there any solution for revert the KNOX trigger or should i use my special "warranty....?"
[Galaxy S 4 Mini General] t5s:
The KNOX bit is kind of a hardware fuse AFAIK, to indicate if the phone has been tempered with. This is relevant for enterprise security related applications. It is triggered when custom recovery or ROM is flashed (an booted?). It's not reversible. But there are a lot of people who are happy running a custom ROM with a KNOX status of 1.
[Galaxy S 4 Mini General] marcooleo:
How about opening the phone and localize the **** and replace the item and solder a new one?
[Galaxy S 4 Mini General] t5s:
Google for KNOX efuse emmc brings this up:

http://forum.gsmhosting.com/vbb/f672/regarding-knox-s4-1775213/

So, you might as well go take a walk in the sun and relax enjoying your fine phone with a good custom ROM.
[Galaxy S 4 Mini General] marcooleo:
I Do enjoy my nice custom rom ?... But Samsung irritates me, i will open the device and fix the board and post a tutorial when i am done.
[Galaxy S 4 Mini General] Chamelleon:
I can tell You one thing (Samsung not playing fair so we don't need to), info directly from Samsung - if phone doesn't turn on they don't check it why and just replace MB. Conclusion - make it completely dead so they can't verify knox status.
[Galaxy S 4 Mini General] qbert456:
What's the best way to completely kill a phone? Hypothetically of course!
[Galaxy S 4 Mini General] Chamelleon:
Any hardware damage that don't leave any marks. Anyway it's not ethical to do something like this so have some honesty and don't make things like this just to have new MB with knox 0x0 but in the situation when You have broken phone and certainty that Samsung wont repair it because knox.
[Galaxy S 4 Mini General] N0Ntoxic:
If device doesnt turn on for you it doesnt mean it wont for them(service), they can run several tests on it anyway...
[Galaxy S 4 Mini General] Chamelleon:
If Your damage is hardware service doesn't check it. Only software issues are tested.
[Galaxy S 4 Mini General] qbert456:
I didn't say I was gonna do this I must add!
[Galaxy S 4 Mini General] marcooleo:
Doing a brick and put some 24 Voltage or little higher in the USB-input, and at the pins in the SIM-card slot will be enough to break some circuits. Be sure to remove the battery first.
[Galaxy S 4 Mini General] Chamelleon:
This case has two sides: one it's not fair to make something like this and two there is some reason that Samsung don't repair motherboards but replace it so it must be included in cost of phone. High voltage is best option i think.
[Galaxy S 4 Mini General] marcooleo:
Well i think it's not fair of Samsung to forever disable updates because of rooting the phone. This ****-treatment to the customers is not acceptable.. So personally i will with a smile on my face fix my phone and get another one before the warranty is out..

Some questions about getting rid of knox

Hello! I have i9192 with I9192XXUBML2 firmware and knox-enabled bootloader. My knox warranty is 0x0. I want to downgrade my bootloader to that version that was before introducing knox. And I don't want to set knox flag to 0x1. I tried to search some information about knox, and as far as I understood my phone will be bricked if I'll try to flash older bootloader via odin/heimdall. But I could not find any information about alternate ways of downgrading bootloader.

For example, what happens if I'll get root using Root de la Vega, then write bootloader image using dd directly to mmcblk device? Will my phone be bricked? Will knox flag be triggered?

Also I've found that there is SDCARD MODE that allows to flash bootloader using image from sdcard. Will this way work for downgrading bootloader?

Can I downgrade bootloader without triggering knox flag using JTAG?

Thanks in advance.
[Galaxy S 4 Mini General] rulex231:
Help

Hello,

I have a I9192 duos S4 mini thats bricked and its knox warranty voided, all this because I flashed 4.4.2 using odin not knowing this would happen :crying:

What I want is to get my device working again, when I try to access recovery mode its stuck on the boot screen with the 'RECOVERY BOOTING...' text and no response.

I've tried to flash back 4.2.2 JB but odin shows fail because of KNOX.

What I want is if there's any way I can get my device unbricked with or without resetting the KNOX flag if possible, any other information required to help feel free to ask.

Also I want to ask if having the KNOX warranty flag to 0x1 caused my device to get bricked or not accessing recovery mode, because im not really sure what caused my device to get bricked.

Thanks in advance.

Flash Your phone with Odin using this PIT and latest official firmware for Your phone.
[Galaxy S 4 Mini General] defaultwpuser:
Is it true that flashing to lollipop with no knox bootloader will remove it? I have read that some people were able to reset from 0x1 to 0x0 just by flashing to newer fw, can anyone test these methods:

- flash no_knox latest fw to a phone with knox installed

- flash latest fw to a phone with 0x1..
[Galaxy S 4 Mini General] sasank360:
DO NOT TRY THAT. You cannot remove knox bootloader. Just try to live with it.

Think of it as your evil twin brother who is as intelligent as u. :p

There is no official lollipop for s4 mini. Only custom roms which do not come with any bootloader.

Flashing old firmwares will not remove knox. It is impossible.
[Galaxy S 4 Mini General] rogier666:
Nope.

Tripping the knox flag is a hardware change (like blowing a fuse) which no software can repair. The only way to go from 0x1 to 0x0 is to replace the chip with the blown fuse.
[Galaxy S 4 Mini General] rulex231:
Thanks for the idea but unfortunately it didn't work :/
[Galaxy S 4 Mini General] Chamelleon:
Then try to install TWRP and format all partitions and next flash stock with PIT.
