4.3 Update for T-Mobile M919 ~ DO NOT UPDATE IF...

T-Mobile finally pushed the 4.3 update earlier today but DO NOT UPDATE YOUR PHONE IF YOU WANT TO KEEP YOUR ROOT! It comes with a locked bootloader. Therefore, once you are on 4.3 stock, you can only flash stock firmwares then. If you try to root your phone on 4.3 with the standard method, it will blow your efuse and void your warranty!
AGAIN, DO NOT UPDATE 4.3 VIA OTA OR ODIN IF YOU DON'T WANT TO VOID YOUR WARRANTY. IF YOU HAVE NO PROBLEM WITH THAT, FEEL FREE TO UPDATE
Info on KNOX:

What we know so far (I think!)
1. Upgrading to newer Samsung firmware will upgrade the bootloader to knox bootloader. this will give an additional 2 lines in download mode about knox status.
2. If the Knox warranty void line says 0x1 then you cannot use knox softwareas your device has been flagged as insecure. By this i mean that if your workplace / company supports bring your own device to work for corporate emails etc and they use knox to keep security your device will not allow this. You are still able to use future samsung firmware releases with the knox flag 0x1. hope this makes sense. sorry for any confusion this has caused!
3. If the knox warranty line says 0x0 knox will work.
4. with the new knox bootloader root will work, however rooting with CFautorootwill trip the knox flag. thanks @DjeMBeY for correcting this point you can use the root method (Root de la Vega) described here for rooting a device with knox bootloader.
5. If you try to downgrade to earlier firmware / bootloader it will set the knox flag to 0x1 i.e. void.
6. once the knox flag gets set to 0x1 there is no way to set it back (that anyone has found yet anyway!)
7. some newer 4.2.2 software that's supplied with the knox bootloader has been repacked by devs to not use the new bootloader and it all works fine you can still keep up to date.
8. I've seen people trying the test build of 4.3 touchwiz without the new knox bootloader sound and wifi does not work. This is no longer the case, see point 12.
9. There seems to be a big question mark as to weather Samsung will allow hardware repairs under warranty with the knox 0x1 flag
10. only seems to affect GT-i9505 at the moment!
11. Software affected thanks to @DjeMBeY
12. it is now possible to install custom 4.3 TW roms which have been modified to work without the new knox bootloader, do make sure that they are free from knox bootloader before flashing. Do note also that if you already have knox bootloader flashing anything even these 4.3 custom roms will still trip your 0x1 flag

DO NOT FLASH MODEMS/BASEBAND EITHER..... does not let u make phone calls on the leaked 4.3 tw version..... or the regular 4.2.2 version and like some1 said 4.4..... not sure if it works on the official 4.3 tw released today since no dev has released a rom of it... so do not flash if u need to make or receive phone calls makes ur phone freeze and wont make the actual call

I dont think it comes with a lock bootloader but more of with new knox flash counter.

Along w/ no calls, does it include breaking sound?

All Samsung bootloaders have been locked after MH8. This is part of Knox security.

How about doing that?

@jovy23 flashed the OTA and now cannot Odin a custom recovery nor revert to MDL. Odin fails every time. I have a locked Verizon S4 I bought for testing (not much good that did) this is the exact same thing I fought weeks to brake.. Nothing. It is locked.

There is a Odin tar for T-Mobile MDL modem here. If you didn't take the OTA but Odin the modem you "should" be OK with this. Be sure to thank the OP of that thread!

I just wanted to throw this out there... I had the stock ROM but rooted. Did my update through Kies fine. My data stayed intact. However, as some others have reported, I lost my root. Now I'm not sure how to get it back. I've seen mention of rooting it another method will void my warranty but I can't find info on how that's done.

Thanks dude. I was to the point that I didnt cared if my knox counter was stripped but now with lock bootloader plus lock modem it seems useless. Samsung is trying really hard to keep it lock.

[Q] JB 4.3 always blocking SU and other root tools on device

hi there, i'm sorry about this thread i open
i need help, how to root JB 4.3 on N7105 without any blocking from that ROM?
coz all root tools on device automatically blocking by the software.
thank in advance

I used FC_Auto_root from chainfire. It worked eventually when he updated the app SuperSU. I could then disable Knox and now I have root access.
Be aware that you will probably get "KNOX WARRANTY VOID 1" when you flash FC Auto Root.

I don't know if there is a safe way. And if you have the Knox Warranty Void triggered, there is no way to untrigger it, as far as I know. Maybe it will be possible when the clever people have had some more time working on it. Unless it's an eFuse, as many people believe...
Anyway, when I first rooted the phone and started it, SuperSU was constantly being closed by Knox. But after chainfire updated SuperSU to 1.80 I was able to update it from Google Play and start it. It told me that it had detected Knox and asked me if I wanted to disable it, which I wanted. I can't find any settings in the app that says anything about Knox.

the first time is ok but after i stuck in stupid "Firmware upgrade .. ... connect to Kies and try again", i flashed again 4.3 and the SU doesn't work. Anyone can help me?

[Q] Can I downgrade to remove knox?

Hi
Earlier this week, I received a notification saying that a new official Samsung update (4.2.2) was downloaded and needed to be installed.
After installing I realized that 4 Knox applications were added to the App list, and there were more counters listed in downloading mode.
Is it possible to downgrade back to the 4.2.2 that came with the phone to remove Knox?
It came with I9190XXUAMF7, and now it is on I9190XXUBNA1.
Thanks in advance

no ..and btw you should have been more careful about that .. u didnt have knox bootloader now u have ... if u flash any other bootloader or rom before BNA1 ur system will crash u cant downgrade ..also knox when turned from 0x0 to 0x1 it cannot be reverted back for now so u lose warranty if u have one

And if I do a hard reset?

Makes no difference. There's no way back.

There's no way back. If there was, everyone here trying to mod their phone and not lose warranty would be really happy and there would probably be more than one thread showing you how to do it.

[Q] Modified Note 3? Won't let me update :(

Hey, everyone! I tried googling this for hours and I still haven't found a solution, so here goes:
A couple days ago, I deleted an important image from my T-Mobile Note 3 and I was freaking out, searching high and low for a solution. I read on Yahoo! answers to download DiskDigger, but the device must be rooted in order to install it. So, I tried to root my device with KINGO Root, which totally failed and then my device just went into bootloop and I thought I messed up my device for good. Luckily, on a different thread someone suggested to use the Youtube video GalaxyNote2Root made to unbrick my Note 3. (Even though it was for Note 2, it was the same concept and I did find the stock firmware on samsung-updates for my Note 3.) It ended up working successfully and then I continued to try root my Note 3 using Odin and the video instructions on xda forum (which I should have just done in the first place) and that worked successfully, too.
Now, my problem is, is when I went to update my Note 3 under settings, it says "Your device has been modified. Software updates are not available." I tried using Triangle Away (I don't know if I did it correctly) and also 1-click unrooting my device in SuperSU. I'm a huge noob at this rooting stuff, but what I gathered from all the research I did on Google, I apparently tripped "Knox". When I go into download mode it reads:
Current Binary: Samsung Official
System Status: Official
Knox Kernel Lock: 0x0
Knox Warranty Void: 0x1
So, a couple questions I have are, how do I "unmodify" my Note 3 so I can get updates? Is there a way to reset my Warranty Void back to 0x0? Will this always happen if I want to root my Note 3? Thanks in advance!

you can not revert knox back to 0x0, no method so far for this....
so you can receive updates, just flash through ODIN, the firmware ... I believe all Samsung phones and tablets will tell you about being modified for updates, if you rooted the phone.

well, you can just reodin a stock unrooted firmware, and then otas will work again, but Knox is basically always tripped.

why even use odin when you have SAMSUNG KIES. put your phone in download mode first, load KIES on your computer, then go to tools>firmware upgrade and intialisation and then follow the step by step direction.
if this helped just press the thanks button!

Can you link me to an unrooted firmware? And when I flash my device with the unrooted firmware, do I uninstall root first or will this just take care of the whole thing?

I tried unrooting the phone and it was still not letting me update because it was still "modified". I thought this was because I tripped Knox, but maybe I didn't unroot correctly??

when u flash the stock firmware in Odin it will overwrite root, so no worries. just follow the first part of this guide. obviously don't flash root, or custom recovery. just follow the first part of this http://forum.xda-developers.com/showthread.php?t=2765014
or, you could also go to a website called sammobile and download the latest ne6 firmware. The link I provided is also the latest ne6 firmware guide, and like I said just follow the guide up to the the root part and you will be good. it will over write root, and whatever else. good to go.

yea, you must of done something incorrect. now, you won't have any updates after following the ne6 guide, as you will be on the latest firmware. but if you continue to stay on it you will indeed be able to grab otas when they come. personally I would just root, stay rooted, and keep up to date with roms, and kernels, and all that crap.

Samsung Note 2 LTE (N7105) Stuck at Samsung logo after 4.3 to 4.1.1 downgrade

Hi guys,
I'm new to this forum and I am a beginner so I must apologise in advance for my ignorance.
I was looking to downgrade my Note 2 from 4.3 to 4.1.1 to unlock it, and I found this http://forum.xda-developers.com/showthread.php?t=2612485
I followed the instructions properly. I rooted my 4.3 with CF auto root, and then I tried to flash the 4.1.1 firmware onto my phone.
Now it is stuck at the boot screen, and I'm so shocked because I did everything correctly.
I can still get to "ODIN Mode" by holding volume down, home and power, and it says:
Current Binary: Custom
System Status: Custom
Knox warranty void: 1
What have I done wrong?
Thank you.

On the first post that you've followed says that "It may or may not work for you" so you only have 50% chance. AFAIK 4.3 firmware has Knox already. Did you flash the 4.1.1 successfully? If yes, maybe Knox is restricting it from booting. If not successfull, maybe the files of your device have been messed up. So you have to flash again your previous rom using Odin. Why don't you try it. Since you already tripped your Knox to 1. Meaning you've already voided your warranty.

What does it mean for me now that I've voided my warranty? I can't update it anymore with Kies?

Great! AFAIK you can still update with kies. But you have to unroot your device first using supersu. There are a lot of rumors around there. Some said yes and some says no. Haven't tried it myself before actually. I always use odin. Since you got back to 4.3, what's your next plan? Hehehe.

Ok got it, thanks man. I'll probably use Odin from now on too.
Is there currently no way to restore the Knox count? The phone doesn't have warranty anyway but if I can't use Knox enabled software in the future I guess it will be difficult
Since I'm back on 4.3 I'm looking to see if I can unlock my phone somehow, I'm looking to study abroad soon and I need it done, and I can't do it through the official carrier so I'm a bit desperate. What do you reckon I should do?
In the tutorial that I mentioned in my first post, he didn't say that I should factory reset the phone. Shall I try downgrading again and then do the factory reset? Will it help at all? Like it says here: http://www.droidviews.com/how-to-downgrade-firmware-on-samsung-galaxy-devices/2/

Downgrading from Knox-enabled-bootloader to Non-Knoxed-Bootloader may brick your device. Your lucky that it didn't happen on your first try. From what carrier are you locked on? Since your on 4.3 Knox bootloader, maybe you can try other custom rom that depends on your current bootloader. Or try to upgrade to Official 4.4.2 from sammobile then install PhilzTouchRecovery 6.26.6 then root it, then find a custom rom that fits your device and can also unlock your device. Maybe you can ask Dr. Ketan if he has a rom like in this thread http://forum.xda-developers.com/showthread.php?t=2472270 for your device. And I think he can help you with all of your concerns. Cheers!
