Hi Folks,
Apologies if this is the wrong place to ask...
I would like to Custom ROM my S4 and have been reading through this thread http://forum.xda-developers.com/showthread.php?t=2447832 about Knox. It would appear Knox hasn't been activated on my phone yet as there's no mention of it in Download mode, here are the details gained from Settings and Download mode:
Android 4.2.2
Baseband: I9505XXUBMF8
Build: JDQ39.I9505XXUBMF8
SELinux: Permissive
Secure Boot Status: Type: Samsung
Device Status: Custom
Odin Mode:
Product Name: GT-I9505
Current Binary: Samsung Official
System Status: Official
CSB-CONFIG-LSB: 0x30
Write Protection: Enable
I am rooted but have used TriangleAway to set status back to official without any problems, my question is am I safe to install Custom ROMS/Kernels without triggering Knox warranty void? If so and I wanted to install a modded Samsung ROM will this still be safe or will it trip Knox?
Thanks for any suggestions, I'm never normally this cautios about flashing, but I really don't want to screw up my warranty.
Many thanks,
R.
If theres nothing about knox warranty 0/0 in download then u are on old bootloader and safe. Dont know about the custom roms I guess stay away from any mh8 mh5 mgg fw. Im pretty sure they are they fw with new bootloader. But just keep searching round.

I've just bought a new S4 and it will arrive to my home in this week.... I hope it will arrive without Knox feature so I'd like to understand too what to do and what to not do in order to prevent Knox problems.
I think I'll flash the Google Edition ROM... any suggestions?
Thanks Buddy

Current binary: custom
system status : Custom

i am really in delimma i don't know what will happen because of the new bootloader i can work or not.. Just need reply if i cannot downgrade or upgrade using ODIN then it's usless of keeping this phone i have to sell it that's why i need fast reply !!!
No. Can you upgrade to official 4.4 - probably, given if you have the Knox bootloader you can flash firmware the same or newer than what you have, but not firmware with the old bootloader.

*cough*
I've already answered your question (and the answer is easily found in hundreds of different threads here/elsewhere anyway). And as I said to someone else on here a week or so ago, I find repeating myself tedious in the extreme.
Hi guys,
I got my s4 i9505 2 weeks ago.
After booting I updated to Android 4.4.2. After I did that I did some research on how to root my device and was shocked about what I found out. I understand that there no chance of rooting the phone without flipping Knox tag (thus void warranty). I understand that there is a way (saferoot) if you have a pre 4.4.2 rom which I don't have any more. I read in the Knox Q&A that there is a method called root de la vega which does not flip the Knox tag. But if I understand the thread right you have to flash a rom and that will flip the Knox tag. I am lost here.
Further more I read that Samsung sometimes refuses to repair even hardware damages if the tag is flipped to void warranty.* I paid so much money that I really do not want to take that risk.
I could not find answers to the following questions. Maybe u guys can help me:
Is it true there is no known way to root a s4 with android 4.4.2 without flipping knox voiding warranty?
Is there no way to go back to a previous rom and use saferoot without voiding warranty?
Are developers working on a solution or will I have to decide to void warranty if I want to have root?
What does the Knox 0x0.sh in root de la vega method do ?
Any help is much appreciated. Thanks guys !
There is no way the S4 to rooting without the Knox Counter to increase.
There is also no way to get back on Android 4.3 back.
To my knowledge there has not yet made no developer Knox to crack.
But your device i9505 support triangleaway so you can clear your flash counter but for i9500 it doesn't support yet.

Towelroot seems to be an option.
I managed to root my device Knox 0x0 !! Can you guys comment on that ?

yeah, I used towelroot and no knox was triggered !! amazing!
rooting 4.4.2
If you are on stock rom you can downgrade your kernel via odin and use towelroot to root without tripping knox. Then flash back the correct kernel for your room. Knox 0x0 but device status will be custom.
hi i flashed a custom firmware on my n900 and as i like stock more i flashed a official stock lollipop fiirmware again everything works fine but when i click knox it say unable to set up knox and closed and in odin mode binary is official and knox warranty viod is 1 ..... someone help me out to sort this problem please and use knox as it were before fully working thanks in advance
So guys, i got a little bit confused about knox 0x0 - 0x1 - root - custom roms etc.
I own a note 3, when it was with kitkat i've installed twrp through odin and got "knox 0x1 (1)" then i went with official lollipop firmware, and now i've reflashed twrp for installing cm12.1 getting knox 0x1 (2). From what i understand, there is no way to revert knox to 0x0, isn't it?
If i had a brand new note 3 with lollipop and knox 0x0 could I install custom roms without tripping it? or even get root permissions on the stock rom?
what also keep me confused is: why there are so many alert in the note 3 section on xda about tripping knox while in the s5/s6/note4 sections everything seems to be much easier? can you please explain me?
PS: execuse me if i've had not been so clear but english is not my first language
Nope, the device's virginity is lost, that baby is done, unless you have the Exynos version, where KNOX status could be reset
Thanks for answering. So i got a friend that would like to install the cm12.1 on his knox 0x0 N9005. will he trip it?
Not much idea mate. But I think there is a possibility that he might not trip it, at least I have seen something like that. Obviously the standard method of flashing a ROM via Odin or or from custom recovery will trip it, but I think there's a way to avoid that, not the usual way of course. You might ask to those who have already done it, or in the CM topic itself, if there is one.
