[Q] Upgrading to 4.3... some questions beforehand

Hi there,
I haven't been updated on rooting and all that jazz in a while, so please excuse my ignorance.
I have a Galaxy S3 (SGH-T999) on 4.1.2. It's stock rooted, but I don't have a custom Recovery or anything on it. I didn't (and don't) want to trip the root counter.
Is there a way to upgrade my phone to 4.3, have root working, and not trip the root counter? (Basically, what I currently have, except on 4.3)
Also, I Googled this new Knox feature I've seen people talk about, it seems like a lot of people here don't like it-- should I not want it on my phone too?
Happy holidays,
-Proxin

The counter is easy enough to reset if still on 4.1.2, so your best bet is to install a custom recovery through odin, then flash docholiday's 4.3 stock deknoxed rom and the new modem, and the at&t kernel for working wifi. This way you can use triangle away to reset the flash counter. If you install 4.3 with 4.3 firmware, you will not be able to root without tripping the knox counter.
Hope this helps

From what I understood back in the day when I got root, if you installed a custom recovery, you either triggered the counter or lost all your data/wiped the phone. Is that still the case?
Edit: Or was it un-tripping the counter that caused the data to wipe?

If you want 4.3 touchwiz, root, and a warranty, all at the same time, don't take the official update.
Instead, flash the 4.3 ROM zip, 4.3 modem, and a compatible kernel, using twrp or cwm recovery.
If you ever need to odin, do not use any version newer than MD5 or you are stuck with Knox and can never go back.

It still triggers the counter, but it can be reset. It did not wipe my data, but backup just in case. Resetting the counter did not wipe data either. But do not update to the official 4.3 if you want to root and still have a warranty.

Uh oh. I searched around for guides on updating like you guys said, and followed the guide here which promised root, 4.3, and no root counter... and now I can't use root, even though I installed a pre-rooted ROM.
I'm on 4.3 now, but don't have the ability to use root. I don't seem to have the Knox thing though.
I don't understand why I don't have root on a rooted ROM... what should I do?
Edit: This is the exact version I used: root66_TMO_T999UVUEMJC.tar.md5

To fix root, enable developer options by pressing build number 7 times, then enable root access for apps and adb under dev options.
MJC is TW 4.3 which includes knox. AFAIK the root66 version has knox removed from the rom, but it is impossible to remove it from the bootloader.

I checked in developer options after pressing the build number 7 times, but I don't see anything about enabling root in there...
Do I have to re-root somehow? If so, will that throw off the counter?

That's why posts need read completely. It clearly says it will trip the Knox counter in 4.3 in the second paragraph of the first post under "4.3 notes" sorry that happened though.:banghead: Maybe someday someone will come up with a knox bypass in the bootloader.

I don't understand-- it seems like it says Knox is removed in order for root to stick:
4.3 Image Notes: With 4.3 images, KNOX is removed in order for root to stick. This will flag the Knox counter. Once you flash one of these 4.3 images you now have the latest factory stock bootloader, radio, etc. Flashing a prior bootloader can hard/soft brick your device. Please read and understand what you are doing.

I took it to mean root will flag the Knox counter so it has been removed from the images.
The wording is very ambiguous...
I'm pretty close to just nuking my install and starting over with CyanogenMod, not caring if I trip the counter or not. Is it possible to do so with the current setup, or will I end up with a brick/semibrick somehow? I figure I might as well, since rooting will likely trip the counter anyway.

Yes lol

"It has been removed", it being Knox haha. That's how I understood it...
So yes, it's possible to get CyanogenMod working without a brick or semi-brick coming from this version I installed?

Yes, I could have been worded better. You can flash other
ROMs but make sure they don't include an older bootloader or your device will brick from what I understand.

I ended up just saying "eff it" and hopped onto CyanogenMod. Probably tripped the root counter, but by now I just don't care anymore.
Thanks for helping me in this thread though, I appreciate it.
Take care and happy holidays.

You did trip the Knox counter.
Just so anyone else reading this thread knows, if you value your warranty DO NOT UPDATE TO 4.3 VIA ODIN . Instead, flash the 4.3 rom , kernel, and modem zips in CWM or TWRP recovery.
Do not Odin MJC (or MK4 for you T999L people) if you want root and warranty, as once you are on the Knox boot loader you can't go back.

One of the things that bugs me about forums, finding information is a pain the butt. I just want to get my device back to stock so I can get OTA updates, GPS doesn't suck, and can use Wifi. I don't care about root anymore or using custom roms. I'm learning Objective C right now to branch into iOS development. I'm sick of the Android ecosystem, to be frank.
I'm on Wicked Rom with Android v4.1.1
Baseband T999UVDMD5, Kernal 3.0.65-DeviantKernel_07
I'm downloading T999UVUEMJC_T999TMBEMJC_TMB.zip right now, along with root66_TMO_T999UVUEMJC_2.7z
Which one do I need to flash? if root66 gives me root, then cool I'll take it, but as I said, I don't care. I'll be using Mobile Odin since I'm on a mac and I sold my PC. If I need to install Windows via bootcamp then so be it, but I really don't want to.
If I need to update the rom, kernel, modem, etc all separately where do I find those files? *scratches head*

Full 4.3 M919UVUEMK2 Succesfull Flash

hope this is the correct place to post this. i wanna post this to help those that are/were in the same boat that i was in prior to flashing the full 4.3 MK2 tar file. excuse my noobness as i'm not sure if the 4.3 M919UVUEMK2 is bootloader or baseband. if you know what it is, please correct me. thank you.
current rom i'm using is the infamous alpha s4 12.04 12.14.2013 (release date i think) --> http://forum.xda-developers.com/showthread.php?t=2362636. after flashing this rom, there are countless issues regarding loss of data, call drops, etc. prior to flashing the full 4.3 M919UVUEMK2 tar, my issue was more on the side of not sending and receiving mms w/o having to disable wi-fi (after flashing 4.3's modem.bin to change baseband from MDL to MK2). unfortunately, this didn't really help me at all, honestly, til i read:

i've also searched about getting KNOX'd. sure i was scared about voiding warranty, because i have this s4 for about 3-4 months only, lol. in any case, i downloaded the full 4.3 M919UVUEMK2 tar file (read this post from same thread above: http://forum.xda-developers.com/showpost.php?p=48669487&postcount=4399), and flashed it, rooted my s4, flashed philz recovery (the latest), clean/wipe phone, and re-install alpha s4 12.04. after doing all of this, i was worried again about getting KNOX'd so i double check and triple check and no KNOX -- me very happy. the only downside is that triangle away doesn't seem to work on MK2, so my counter is 4 and, yes i can send and receive mms w/o having to disable wi-fi . i will constantly test calls on this rom to see if there will be any drops or what not, so we'll see how it goes.
hope this isn't TL;DR lol. i'm still very new at this rom scene, and i hope to get better as a user because i can't program worth a damn :laugh: also, i hope that this will help or lead others to help them in finding their solution in other 4.3 roms out there.

To answer your question, the mk2 is a firmware version. But if you break it down you have a mk2 boot loader, mk2 modem, etc etc. The firmware contains all these things and their all mk2 version. So you can have mk2 firmware, mk2 bootloader, mk2 modem/baseband etc etc. Mk2 is just the firmware they came from

Hate to break it to ya, but that is not the mk2 Knox enabled bootloader.
If it was , under system status it'd say Knox kernel lock 0x0 and under that Knox something else 0x0.
The link you got the firmware from, which was on Jamesons AFH, must of contained the mdl bootloader

i thought i did reply correctly. like previously stated, i don't have another phone or camera on hand to take a pic of my Download mode, what i listed is all that i saw on when i'm in download mode. so, there is no KNOX Warranty Void: 0x0, or 0x1 on that screen.
pretty much like shiny said above, the mk2 tar file that i flashed from jamison904 did not have the 4.3 bootloader in it; and it seems to be a good thing lol. hope that helps.

I am not sure that it did not trip the Knox security..

The only way to find out if it 0x0 or 0x1, is to install the Knox app itself !
Yes, it will let you install it to a certain point & when you try to set it up (if your Knox is tripped) it will tell you that it can't be installed !
Then you can uninstall the app.

There is no much discussion on this application (for none rooted or custom ROMS), but if you manage to not trip the Xnox security flag, this app is somewhat a nice to have.
It creates a second UI (User Interface) on your phone with ability to customize it completely differently from you regular settings with some Samsung (I know, many will considered it as bloatware) specially design apps for Knox.
It is useful especially, if you intend to keep some concealed info, documents & videos...etc.

Not true.... The flag is displayed in download mode. Just like the flash counter. So to see if you tripped it you do exactly what the op did. Boot into download mode and you'll see 2 lines regarding knox with values. 0x0 if not tripped 0x1 if tripped

If it's not displayed in the bootloader, said user doesn't have the Knox infused bootloader. So there's nothing to check. I think you're referring to the other flag. The flash counter. Which isn't the same thing as the Knox.

My question really is how did this happen? I thought if you flash that Tar file you automatically pickup the 4.3 baseband and knox with it. Could this be remaining from you updating just the modem? For me the problem is that I cannot seem to update the modem to mk2. I do not really see any advantage of locking the bootloader with Knox and if my screen stops working stupid T-Mobile will find a way to refuse to fix the phone!

Do you think you can point me to a package like that where I will not pickup the bootloader? I have been trying to just update the modem using odin and keeps failing. Maybe flashing a non knox tar file will do the trick to get everything to work properly so that I flash 4.3 finally!
Maybe the OP can also post a link to the package he flashed using Odin!

Reflash the knox bootloader maybe?

Im on the official 4.3 stock rom. Did the cf auto root and tripped the knox bit.
The thing is in TWRP recovery you can nandroid backup of current rom and asked me what to backup featuring bootloader modem efs etc. And can restore back what was backed up before
I was wondering if someone still in 4,1,2 bootloader with rom too can makae nandroid back for us to try to flash with the old bootloader. Maybe we can overwrite the bootloader like nothing happened?

hey man, don't bother your self,i tried this one before but no result, i have been searching for 1 week to find a trick to get rid of the Knox bootloader and the avoid status in download mod but nothing help, even now my phone does not accept any rom with mj5 bootloader!

I heard that i cant do ota updates if the knox is tripped, is that true?
Sent from my GT-N7100 using Tapatalk

Hello guys as far as I know nandroid backup does not contain bootloader, to flash a bootloader it must be done by odin I think, there is a link I will get it for you by dr keton the great on how to down grade the bootloader but I am not sure if it will work or not with triggered knox (I think it should work as what is the use then)

Backup boot option in the recovery generally means the kernel.
Kernels are named boot.img generally.

However this thread was originally made for 4.1.2 bootloaders. Not sure if it works on knox bootloader.
It uses adb so I guess it should work.

1. Doc keton?
2. The knox security is a multi layer security. Though perhaps it is a software instead of efuse, it won't be as easy as flip ur palms.
3. Samsung may easily boot back ur phone, coz they have the tools (either software/hardware). So, it might look easy on u / whoever have experienced the same thing like u.
4. The dev here most of them are part time d3vs who just do this for hobbies on their spare time. And there's a bounty thread for this knox. My last read is around $3.1, and unclaimed.
5. Be patient mate.

I meant dr ketan sorry am not rushing our great developers here they are doing enough already, I already got mine done, I also to confirm on the dear members here that it is doable and it is only software not efuse, so we should get it eventually.
Thanks for your time mate.

[Q] Short Knox question

If I trip knox, is there anything more happening despite that my warranty could be void and I couldn't use Knox apps?
(example: not beeing able to flash certain things or entering recovery etc.)
Thank you!

Just the warranty bit nothing else

Aight, thank you for the quick response man! :good:
maybe one last question,
are there ways to avoid tripping it always, or is it more like "if you go customizing it fully you'll automatically have the Knox triggered"?

to avoid this is by not using odin to flash bootloader\downgrade\custom recovery or custom kernel
if u touch the bootloader\kernel\recovery or downgrade or used odin to do so u will knox it up ... i knoxed my device as
it got into a bootloop

You can root using saferoot an customize with xposed framework, remove bloatware and everythin that not involve flashing with Odin

It's not android without a custom recovery and kernel etc. :laugh:
Also stock was kinda slow!
So I knoxed it up now lol
Gonna install paranoidandroid on it

[Q] Changing operating systems?

Ok yall I have a brick It was a Tmobile SGH-M919 and the rirmware was M919UVUFNB4. Question, since it only boots into download mode, not even recovery, can I change between M919UVUFN4B and M919UVUEMK2 and M919UVUAMDL?
Just wondering cause I'm trying to learn how to change an operateing system on phones
I've gotten pretty good at rooting and roms now its time to learn something new

M919UVUFN4B and M919UVUEMK2 are both knox enable firmwares. You can change between then but never go back to M919UVUAMDL. Putting on a different rom is changing the os on the phone.

Thanks. Can I simply root and remove Knox? I hate that app as much as my ex wife's cat.
Right now I have 12 hours left downloading the 4.4.2 one so after installation it will be rooted and recovery will be changed to cwm
Oh and why not go back to MDL? Is there a problem with that is or is it just incompatable?

MDL is incompatible with the boatloader, if you have installed MK2 o NB4. You can brick your phone if you downgrade to MDL.

The Knox apps and the Knox flag are 2 different things. They are both security related, but the Knox flag is what gets tripped/set if you every flash a non-stock recovery to the phone.
The Knox apps are what can be used to Shut down/wipe a phone if stolen, etc
If you have ever had the MK2 or NB4 bootloader on the phone, you now have the Knox flag. You can not go back to a bootloader that doesn't have the Knox flag. MDL bootloader doesn't have the flag, so you can't flash it once you've had MK2 or NB4.

Just FYI, the phone has multiple bits of software. The bootloader and the recovery are in their own partitions. The firmware is like device drivers under Windows, and there is the radio(s). And then there is the OS. It's made up of the kernel and the interface/apps.
When you download the stock ROM from Sammobile, you are getting a partition table, a radio, a recovery (stock), the firmware and the OS. Which is why everyone on several threads has suggested you to download and install that with ODIN. It should get you back to a working phone.

Mine trips the counter that says I have changed to a custom rom, so that means I have the knox flag right? Cause when I rooted I uninstalled and deleted the knox app, tried that once before I was rooted and wound up doing a hard reset because of that app

No, the Custom ROM flag is different than the Knox flag.
If you boot into the Bootloader, if you have a Knox bootloader, it will say the words Knox and then have a 0x0, or 0x1, next to the word Knox.
No Knox shown, you have a bootloader that doesn't have Knox.
If 0x0 shown, the the Knox counter is NOT tripped. If 0x1 is shown, then you have a Knox bootloader and the Knox flag has been tripped.

THIS IS INCORRECT! I keep seeing this all the time. THIS IS WRONG. It will NOT brick your device if you try to flash MDL firmware to a NB4 firmware. Odin will simply say "fail" and nothing will get written.
About your issue OP, you need to flash the NB4 tar file in Odin to recover from your soft brick. Then you can flash a recovery or what have you to get back to however you wish. You cannot go back to the MDL firmware after taking the MK2 or higher firmwares. The bootloader will block any attempts(as stated above).

I flashed nb4. Took me all day and night yesterday to download it, but I flashed it this morning and the spare phone is now back in its box safe and sound, I put my gmail address in it simply to make sure it worked, installed cwm recovery and chain fires root, whoever (if anybody) ends up needing it, I'll just do a factory reset and load her up again.
