[Q] Information needed after being inactive for a long time.

So after being inactive for months I came across stuff about "KNOX"(Knox free etc) and MIJ MJ5 stuff and that it looks like its hard to downgrade or something like that, can anyone explain me what exactly KNOX is and what MIJ is?
I assume MIJ and MJ5 stuff is the firmware version.. and roms using those tags in their title are based of them? Or can I only flash those when I have that firmware?
I actually didn't even have any problem yet.. but I've been running official MIUI for the past months anyway..

Sure, maybe you have to search better I suppose.
OK no problem you need help you are saying if I understood well, knox is new security function for secure phone's communication for company use etc, it is using many levels of security starting from bootloader and goes to system etc etc Google it for more information, also knox checking your system for rooting etc and voids your warranty (look at note 3 forum), is difficult or impossible to remove it, but if you have already install it drketan made a patch for n7100 which is removing successfully knox from your bootloader.
http://forum.xda-developers.com/showthread.php?t=2500823
Follow the instructions and knox finished from bootloader, after this
you can downgrade to 4.1.2 use triangle away flash stock f/w restore warranty etc
Little bit more searching noone hurts

So if knox is installed, i will still be able to root, but its somehow setting a value which manufacturers can check and see if I rooted or what? (I also don't believe I have Knox im not sure, i updated to 4.3.x once via odin but only used that to fix my EFS and then go back to CM10.2 and or MIUI (depends on my mood))

You can see if you have or not at download mode volume down +home+power at last line, it is writing knox something.... . Knox is present at mj5 second leak 4.3, if you have it you need to use drketan's 2 patches to remove it before downgrade.
Are you ok now? Your questions answered?

Newbie help on 4.2 to 4.3 tmo (KNOX)

Hello,
Fairly new to android and rooting. Only rooted one phone (Dad's gs2 bc it had firmware and camera issues) but I was successful.
Using a virgin Galaxy S4 on tmobile since april only mild battery issues. Was waiting for uodate and shocked that we only get jellybean instead of 4.4 kitkat??!!
So question:
Upgrade and lock bc of KNOX and just wait?
OR
Dont upgrade and root and add kitkat now?
Is it worth the upgrade?
Galaxy s4 on Tapatalk

KNOX doesn't lock your phone. Its builtin to the 4.3/4.4 bootloader and if you root or flash roms, it trips the flag and voids your warranty. That is all. If you don't care about the warranty, flash away. You can root your current firmware and flash the 4.3 or 4.4 roms that are on thr forums that have KNOX removed. I'm on 4.2.2 and Ive upgraded using flashable roms and came back without having to worry about KNOX

That would be handy, as bouncing around the threads on the update and the initial ROMs being developed leaves a lot of questions and there are a number of soft bricked devices because of it.
Apparently, if you want to stay totally away from knox, you cannot simply flash the new radio as-is, as without having loaded the new knox bootloader, a number of functions will not work. And if you just flash the new OTA based ROMs, you can have problems also,
Work is being done to de-knox the radio, but I don't know where that stands. Nor am I sure if when that is done if you will be able to flash and use the new OTA ROMs and also revert to 4.2.2 without having to first revert to previous radio.
So again, a guide on living with knox would be helpful.

I'd like to know whether, if I upgrade to 4.3 using Kies (I'm on rooted 4.2 stock), I can re-root and remove Knox (as I've done in 4.2). I know I can re-root, and permanently void the warranty, but I don't know if Knox is removable in 4.3.

If you upgrade to 4.3 via Kies you will trip KNOX if you change ANYTHING. Once it's tripped, you can't clear it.
The only way to avoid tripping the KNOX flag is to use a rom with KNOX removed

Can someone clarify something for me. Does having the 4.3 bootloader and knox 0x1 prevent you from flashing CM/GE/AOSP/Non-TW4.3+ ROMs? I've been staying on the old bootloader and am considering just updating. If the knox 0x1 only affects warranty and not flashing of any ROM I want, then I don't care if I have 0x1

Only voids warranty afaik. Why not stick with the old bootloader and just flash new roms without the new knox bootloader? Best of both worlds.

Np. In my honest opinion, this new bootloader is just another middle finger to the consumers under the false pretense of solidifying security measures for the few coorporations that have actual need for KNOX. This is Samsungs way of avoiding responsibility for failed hardware. Okay enough ranting lol. New bootloader serves only as a way to inform Samsung or the store you are returning to that your warranty is void.

He put it in a better way:
Skipjacks said:
As for upgrading to 4.3 you do not need the 4.3 bootloader and you don't want it. It has a way to show that you've previously rooted the device that cannot (as of yet) be reset.
Just flash 4.3 ROMs in recovery. Anything you find in the development section will work fine. But if you want Wifi Calling you HAVE to use a T Mobile specific Touch Wiz ROM. You cannot use just any Touch Wiz ROM or any AOSP ROM at all.
If you want the T Mobile Wifi CAlling on the stock 4.3 rom and don't want all the other BS that comes with it, use this guide...

Umm, many people with real jobs have security requirements for their mobile devices. KNOX has nothing to do with Samsung attempting to avoid responsibility for hardware failures. They have nothing to do with each other. Where did you get this BS from?
I guess it is the interwebs so people can make up anything they want.

I specifically stated in my first sentence that it is my personal opinion. I also stated that corporations do use KNOX but not to the extent that everyone needs to have it pushed out to them without a choice. Quit getting your panties in a bunch and learn to read.

My panties are not in a bunch. KNOX has nothing to do with the samsung warranty in the case of hardware failure. Your opinion is useless if it is based on garbage. Make sure you know what you are talking about instead of making stuff up when giving advice.

Wifi issue - rooted - warranty - 8.4 pro

Hey guys
I am tired of Wifi Disconnections on my 8.4 - it seemed to disconnect constantly, ( showing me connected to XXXX all the time )
I have rooted the device and using custom rom
Now, I filled out the online warranty form for Samsung, its free UPS - for repair now
1) Does anyone have a full proof ( s/w fix ) for Wifi issue
2) How do I unroot and make it so that Samsung cannot detect the root and still fix under warranty
3) Any other advice or has anyone done this?

Did you have that issue before running the custom ROM . it might be ROM related

this could help for your second question:
- install Triangle away and execute it
- download your original firmware: http://samsung-updates.com/
- flash with odin (check NAND Erase All)
that helped for my "old" Galaxy Tab 3 8".
It looks like out of the box now.

You cant do anything to hide the fact you rooted it. Unless you used the new method, the warranty flag was set to 0x1 and nothing can reset it.

[Q] Just got the GTP 8.4. What to do with all this bloatcr*p?

Hey guys. So I just got a Samsung galaxy tab pro 8.4 and it's full of crap. I also read that installing a new rom will mess your warranty right? Will rooting it also mess it?

yes both rooting and flashing puts an end to your warranty
the first thing you can do which will make quite a difference is go to settings / general /application manager and tap on each one of Samsung's bloats - there must be more than 30- and see which ones can be disabled. they are quite plenty. disable them you will end up with a much lighter touchwiz
it is totally harmless and needs no rooting.
off course after rooting you can freeze all of them but first things first
oh and enjoy your tab!

I already deactivated some of them, but I'm a bit afraid of deactivating something I shouldn't. Is there a list of what I can deactivate?
I also installed nova launcher and the same icon pack I use on my phone.
EDIT: also, how do you add/remove widgets on the lockscreen?

It will definitely not remove the hardware warranty...

wut? the rooting or installing new rom?

Why not install towel root (depending on what firmware you have) then su pro and then install titanium backup and remove or freeze the bloat Ware. If anything goes wrong just reflash the original firmware for your region and all is good again. That's exactly what I have done mate and it didn't trip knox either.

The problem is that I heard that it eliminates all warranty..

Both. You'll find nothing that states this nor I the contract you so signed or on Samsungknox website. That's a myth.
And even if it was this wouldn't apply in Europe or in the US..
Was is removed is Knox warranty. Meaning that the device has been tampered with.

Knox is like secureboot with PC it creates a chain of trust from bootloader up to ROM. If anything of this chain is modified Samsung will not feel responsible for any software related bugs or software security concerns.
Hardware warranty is lost only if the manufacturer can prove that your software modification resulted in damage. Over clocking or playing wih thermal threshold are such cases. Rooting or flashing is not..

I could confirm that:
Towel root does not trigger any visual flags
Flashing a ROM (like CM11) does trigger "Kox Warranty Void" flag but not "Knox" flag.
So if one likes to play safe from ServiceCenter point of view, rooting is a bit safer option...

can't you temp root it?
then you can remove the bloatware and when you restart, you are not rooted!

a5 knox thread

Do a research about the new knox. It.s an e-fuse. Once that bit is burn on the emmc, it can.t be erased

However there might be at some point a kernel which spoof Knox. This won't reset warrznty but you'll at least br able to use things like pay

Ok, I have been looking for knox and e fuse and I totally understand now. To bad it is done this way.
