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.

I install N7100XXUEMK4_N7100ODDEMK1_N7100DDEMJ9_INU on my N7100 and I not rooted???How I root this device and install custom rom Omega,Phoenix,etc??Please help me....
You can root your mk4 firmware using instruction from here:http://forum.xda-developers.com/showthread.php?t=2540761
To install custom roms,you have to first install a CWM/CWM based recovery and then flash the rom.There are different instruction for flashing different roms and you can find them in their respective threads.
CWM is installed...but bootloader in mj9 is locked????
Sent from my GT-I9505 using xda app-developers app
If CWM is installed in your device then I guess you have already void your warranty,but if not then you can root by this method:http://forum.xda-developers.com/showthread.php?t=2553647
This wont trip your knox counter and your warranty will be intact.
No.the bootloader in mk4 isn't locked but after installing this bootloader you cant revert back to older bootloaders/firmwares.
The knox counter wont allow to revert back to older bootloaders.

Ok,and what I doing now?
Hello,
I want to ask or confirm something for me.
Now i am on stock 4.3,not-rooted,Knox flag=0
If i decide to ignore this KNOX flag and warranty i can :
Root it - using Kingo root Correct?
Flash custom recovery - Witch one ,because i read that some have problem with custom.
Flash custom ROM- Phoenix (let say). Correct?
After rooting i will be able to disable KNOX ,witch after flag 1 will start showing some notifications. Correct?
After KNOX flag 1 the only thing i am not be able to use is KNOX (application) -Correct? I don't use it at all.
Thanks for every respond!
P.s
Is there any other way to flash bootloader except Odin? And if yes HOW?
Asking because :
KNOX is flag in the Bootloader. My idea is - Flashing old bootloader trough Odin-not possible.
BUT if the is other way(not odin) to flash it until KNOX is 0,maybe later it will stay 0 when stock is flashed trough ODin
I tryed on mine 4.3 and knoxed it anyway. CF root seems to not work properly anymore.
But who gives a ****. Knox is justa bunch of crap.
KNOX on stock recovery show 0x1.show after my knox has been triggered can I flash any DEKNOXED JB 4.3 firmware by odin to get rid of knox and root my N7100?What are possible ways to get root and install custom recovery for KNOX triggered N7100?
IMHO you can flash anything, but you lost your varanty.

Hi guys, I'm getting this phone from someone and I want to know that if the phone came with 4.1 without KNOX bootloader what can I do for precautions to not flashing KNOX bootloader?
or, if the phone is came with 4.4 with KNOX bootloader how can I remove it? thanks.
The question should be if you still need to bother about KNOX? THe warranty is probably over and if you have lower bootloader, then flash MJ5 and ROM without KNOX and prerooted like OMEGA, which I recommend. If you have newer bootloader then just flash whatever you want and forget about KNOX

so there's no way to remove the knox bootloader right? So if I got the old bootloader, should I flash MJ5Patch?

If you get bootloader older than MJ5, flash MJ5 bootloader, it is the last one that works with 4.3/4.4.2 that is without KNOX. If you get it with MJ5, no need to do anything. If it's newer - you'll just have to live with the fact that Knox flag will be set to 1.... (if you want to flash custom ROMs)
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
