[Q] GT-I9195 firmware update

so, i'm reading this forum for 2 days now and i didnt get any answer.
i installed stock XXUBMJ7 (4.2.2) firmware with odin. Before i new anything about knox and stuff, I rooted, and get knox waranty void 0x1.
then i installed again XXUBMJ7 firmware with odin and didnt root again. (because i hate warnings at the boot). i still have 0x1.
now, I have two questions and i need simple answer.
1. Can I install newer stock (4.2.2) XXUBMK3 firmware with odin? will it work?
2. can i root my installed stock XXUBMJ7 firmware again and then install [CWM][ROM]GT-I9195XXUBMK3 deodexed, with no knox bootloader? will this work?
thanks

anyone?

But your Knox flag will remain so u can not reset it

[Q] MJ5 'safe' ? If not, what to avoid?

Hi All,
I have a 4.3 custom rom and the MJ5 bootloader.
Mostly I have read that the bootloader is safe and the warranty flag will not be triggered.
However some posts speak about a warranty flag 0x1 while using MJ5.
Is the bootloader completely safe or are there some things I should not flash? (Besides newer bootloader)
Thanks in advance.
Regards

It's not warranty flag, it is Knox flag. It doesn't have anything in common with warranty And yes, MJ5 is safe since it has no Knox.

Does this mean with MJ5 bootloader I can root, flash custom recovery and nonknox-firmware by PC Odin or knox-firmware by Mobile Odin freely without worrying about knox flag 0 to 1?

You can flash custom recovery (Phils v5.15 recommended) and custom ROMs. The only thing that will change is flash counter, but you can reset that with Triangle Away (will be increased each time you go to recovery, so you must run triangle away again), but you don't have to worry about KNOX, if you don't flash ROM wih KNOX (that is update bootloader). ROMs that are flashed from ODIN can have bootloader but if you flash from RECOVERY then you don't have to worry because these ROMs can't have bootloader.

It means if I flash stock ROM 4.3+ wih KNOX by PC Odin (update bootloader), does knox flag security change 0 to 1? If knox security is 1 then no way to revert back to 0?

No, if you flash STOCK 4.3+ with KNOX, you will have KNOX security and you will not be able to DOWNGRADE bootloader ever again. Only if you try to flash other non-official ROM without KNOX, will you have KNOX security 1.
And yes - there is no way to reverse KNOX security back to 0.

[Q] Successfully Rooted with Towelroot on Note 3(SM-N900T), have some questions...

Successfully rooted without tripping Knox with Towelroot. NE6 firmware. I have T-Mobile Jump and would like to Jump to the Note 4 when it comes out. If I install TWRP and make a backup of stock, will I trip knox and void my JUMP eligibility? Wanted to install via Flashify and install Xposed framework at some point down the line.
Thanks!

If I flashed back to stock, did a factory reset, would it still say custom?

As long as you didn't flash a custom kernel or recovery, it should be OK once you flash stock.
Even if you trip Knox, flash back to stock and jump when the time comes. They generally don't care about that as long as your phone is not damaged.
Knox warranty void is not the phone warranty. It's telling you Knox can't secure your phone anymore. Its (Knox's) warranty is void. People all over the Internet don't even know what Knox is and they spread misinformation.
Look up what Knox really is. It is an app that runs on your phone and creates a secure Android environment within itself. It's like another phone with its own launcher and app store that is secure. It's meant for employees to use their personal phone for work purposes as well.
When you trip the Knox warranty, Knox triggers an efuse that will prevent the secure container from being able to be created... Meaning Knox will never work again on your phone. It's a security measure so that companies will take the Samsung phones seriously in the work space. In reality it has worked for them as the department of defense recently approved a few Samsung models with Knox.
If you don't plan on using Knox for anything, then trip Knox and enjoy custom kernels/recoveries etc. If you do plan on using it, it's not a good idea to even root your phone as the whole purpose of Knox is to be secure and rooting will make Knox vulnerable.. You might even get fired if your IT department finds out.

Makes sense and I probably will flash a custom recovery. I just don't understand the fuss with people wanting not to trip knox if they're not even gonna use it.

I successfully rooted my Tmo Note 3 with Towelroot v2. I am currently on NE6 Boot-loader and have Knox at 0x0 and would like to remain there. I would like to upgrade to the new firmware NF1 which is not rootable with Towelroot yet. Does anyone know if using Mobile Odin Pro is able to keep root if manually done without breaking/tripping Knox? I think I remember reading somewhere that it was okay to do so and ignore the message even though it asks to download a file and then it gives a warning saying that:
"Using, Mobile Odin on this device will void your warranty, as the Knox counter will be triggered .This is not reversible".
Can someone confirm if its Okay to ignore the warning and that activating Mobile Odin Pro on my phone is OK without triggering Know 0x1, or was that other posting I read somewhere wrong? I cannot remember where I read it. If not possible to use Mobile Odin without triggering Knox 0x1,. is there any other way to root NF1 without triggering knox on our device? What do you guys think?

un-answered question............
I don't know why I have not asked this before, but here it goes..........
First, I just want to say that I could care less about Knox...
(my phone already has the knox pox)
But for future reference if I had a brand new Note 3 with official stock NB4 baseband
and I rooted it successfully using Towelroot (or root de la vaga) would it be possible
to simply rename a custom rom like Hyperdrive to "update.zip" and copy it to the
internal sdcard then boot into the stock NB4 recovery and flash/install "update.zip"?
If the only problem with this method would be the fact that a different kernel would
also flashed along with the rom it would be an easy fix by just removing the kernel
from the custom rom file before flashing the update.zip?
I know that more likely than not this method would not work.
But if it did work it should not trip the knox right?

I just checked and it's OK to "install" Mobile Odin on your phone and it
it will NOT trip the KNOX counter by simply installing it as long as you:
1: Don't flash any custom recoveries like twrp/cwm.
2: Don't flash any stock or custom kernels.
3: Don't flash any modems/baseband or bootloaders.
4: Don't flash any custom odin flashable firmwares.
In mobile odin there is no option to flash cwm/twrp
flashable zip files of any kind including custom roms.
Good luck!

Why would flashing a stock kernel/baseband or firmware cause Knox to change to 0x1 when done through Mobile Odin? I thought this would happen only through custom based ones?

First of all I never said not to odin flash stock official firmware in my post.
If you or anyone else knows for sure that the modem/baseband or kernel you are
wanting to flash are 100% official stock 4.4.2 Kitkat NB4/NE6/NF1 versions then
its just fine to flash those.
However since knox cannot be rolled back and to keep things on the SAFE side I
always suggest the very safest way to do these things which even a NOOB would
understand without getting into trouble with a lot of unexpected issues. :laugh:
Good luck!

[Q] Note 8.0 Custom Rom

Hi guys I am new to this tablet so any advice but be appreciated.
If i update to kitkat I am told the knox security feature would be installed too.
What if I leave my note 8.0 on 4.2 and root and use custom roms and then if I decide to unroot and flash kitkat, would knox be triggered due to historic custom roms?

Pretty sure flashing a custom recovery will trip knox. No way around it. http://forum.xda-developers.com/showthread.php?t=2800290

Ok thanks what if I just root and not flash a custom rom, would this trigger the knox?

It depends on the rooting method you use. The one I used to root 4.4.2 after I updated via Odin was Chainfire's CF-Auto-Root and that tripped KNOX because it installs an unsigned (by Samsung) custom recovery temporarily before re-flashing the stock version.
I've never used Kingo but they claim to be able to root the Note 3 without tripping the KNOX flag so their method using an Android vulnerability to gain temporary root might work for the Note 8.0 as well.
My suggestion would be to use these forums and Google to research all the current methods for rooting the Note 8.0 and make sure there are users who have done it successfully with the KitKat boot loader installed and not tripped the KNOX "warranty" indicator.
Based on the KNOX articles I've read it appears that flashing, or even booting, an insecure kernel can set the eFuse switch which is said to be "impossible" to reverse, so flashing custom kernels and ROM's is out even if you can get root with the stock ROM without tripping the indicator.
I can understand the requirement for KNOX in high security environments but automatically voiding the warranty is just encouraging users to brick their devices in ways that prevent the KNOX flag from being accessed. Perhaps Samsung's position is that once the eFuse flag is set even their service centers cannot reverse it so the device is not able to reconditioned and sold since a tripped KNOX flag also disables some security features in the stock ROM.
Edit: I just read your OP again and if you don't flash the 4.4.2 (KitKat) bootloader and root with CF-Auto-Root you should be fine, even flashing custom kernels and ROM's, and still go back to a completely stock configuration using Odin to install the stock 4.2.2 ROM and TriangleAway to reset the flash counter. AFAIK there is no check of any historical data when the KNOX enabled 4.4.2 bootloader is installed but I would make sure that TriangleAway has successfully reset the flash counter before upgrading just to be safe.

[Q/A] Answers Added - OTA's/Updates, rooting & tripping Knox? - other questions

So I rooted using chainfires method for my Tab S 8.4 wifi (T700) and it tripped Knox (0x1). I know there is no way to currently reset it and there is a bounty out for it. No big deal on tripping it, I wanted to root anyways and want to try out CM12 eventually. After doing some research it appears Knox gets tripped when unofficial firmware or recoveries get flashed via Odin. Knox is not tripped when you flash official Samsung firmware. I had a few questions though I can't seem to get a clear answer on and was hoping to find some or get a discussion going at least about Knox for the Tab S.
Questions and Answers
- Are you still able to receive OTA updates on a stock rooted rom/recovery with Knox tripped?
A: No, not while rooted, "Operating System on your device has been modified in an unauthorized way. Try downloading software updates using Samsung Kies on your PC" Unsure if Knox prevents it but most likely does not.
- Will you lose root if you can get OTA updates?
A: No OTA Updates allowed on rooted devices. Reports have stated that flashing the official firmware update via odin will unroot the device but maintain data, most likely kies is the same when updating. However if a bootloop occurs after flashing, you may need to wipe data and cache via stock recovery.
- If knox is tripped (0x1), if I flash a custom recovery (TWRP/CWM) or use chainfires method to root again will it trip Knox again (0x2)?
A: YES & NO, Knox will not read (0x2) if unofficial img's are flashed via Odin but reports on other devices have stated it will read {0x1(2)}
- If yes can you trip Knox too many times, rendering device inoperable or bricked?
A: NO, tripping Knox only informs if warranty has been voided by flashing unofficial firmware/recovery/img files and root kernals via Odin. When the knox warranty void status is tripped, the knox software will no longer work.
- What is tripped specifically in Knox (for the Galaxy Tab S), an efuse, or is it software or binary code?
A: Most likely an eFuse. There is no way to reset the flag counter as it is believed to be an eFuse that once gets blown it stays damaged and cannot be reset.
***New Questions***
- Will flashing a custom recovery img (TWRP/CWM) via ADB trip Knox (0x1)?
A: Yes, it will trip Knox.
Thanks to all who answer and contribute.
If there are any new questions, updates to be added or wrong information to be corrected please let me know.

No OTAs when you are rooted on custom rom. Dont worry, someone will make a stock custom rom to flash with twrp Or you can odin flash stock lollipop and root with twrp
If you do the ota it will probably not install because of root.
If you flash a custom recovery, or root again.. Knox will stay 0x1. It wont change.
Knox is like a check when booting up your device. Its more like uhh protection. If you install custom stuff then you dont get protection. Knox was a security feature that samsung included. Its really not needed as it really doesnt work. Thats why people trip it. I highly doubt its used for security but I think its just used to detect if warranty has been void or not. Its not something that you should worry.
Hope this helps!

Thanks, I figured Knox is nothing more than just a feature to let Tech's know if the warranty had been voided. Also I figure that flashing the updates myself when they come out would be the best option. Thanks again.

how do you make the knoxx counter back to zero ??

Read post two above yours. It can not be reset to zero once it's tripped.

Even if you root and trip knox, although you cannot receive official ota's, you can still use samsung kies to still recieve the updates.

updated OP with answers to questions.

Stupid Knox. This is one "feature" of Samsung devices which makes me less likely to purchase them in the future.

For the new question, flashing any custom recovery with odin or adb will trip knox. Flashing stock should not trip
