[Q] Update from MJ5 to MKx 4.3

Hi,
I installed the leaked MJ5 4.3 build, because I wanted to use my Gear.
However, now the official 4.3's are coming and I may want to upgrade to official in the future. MJ5 works fine however.
I have read that people bricked or got "flagged" by just flashing MK4 over MJ5.
Someone suggested to only flash the pda, and keep the mj5 bootloader and flash a "wifi patch", but I guess this is only for rooted phones.
What changes/methods are there to go to official, while remaing unrooted, fully official and knox capable? (Would like to use knox later on)
Somebody already tried the MJ5 to MK4 road while staying completey official?
Thanks....

Why do you ask? Can it be done without problems? Flashing another 4.3 rom over MJ5?

Well keep the MJ5 bootloader and use the wifi patch. That is the best option.
because MK4 wont allow you to downgrade EVER.(unless you visit the SSC)
Plus it has a KNOX enabled bootloader,so if you try rooting your phone or customizing it EVER you wont be able to do that easily and your phone (in your area) might lose warranty.
rest upto you
You can easily upgrade to the MK4 bootloader by a normal flashing method. But then dont try customizing it. Resetting ghe KNOX flas is not possible as of now.

I don't mind the knox bootloader, not planning to root, no need for downgrading, I am just worried that if the official 4.3 for my region is released I cannot flash it without problems over MJ5.
I also plan to use knox, actually.
That's all.

my 2 cents..
you dont mind the new bootloader.. dont wanna root... dont wanna downgrade..
then use odin to flash any official 4.3 update..
cheers..

Well, one of the guys (thread in my post above) who flashed mk4 over mj5 ran into problems with odin 3.09, but using 3.07 he succeeded, as it seems.

Will you be able to root again after updating to the Official Samsung 4.3 ver

Hi Guys,
Recently our 4.3 update just rolled out for our region. My question is would i still be able to root and restore all my apps using my TitaniumBackup?

Just rooted my phone using Kingo
Galaxy Note 2 GT-N7100
Build XXUEMK4 (India)
Knox Bootloader
WITHOUT tripping the Knox Counter!!!
Though Device status shows "Custom"
Can be taken care of by Using Xpose Framework & Wanam
Thanks.
Major.
Search the forum for further instructions.

Forgot to mention that i have Galaxy note 2 GT-N7105.
Would it be possible to flash 4.3 via odin then just root again. This is coming from a stock rooted firmware.Would the new bootloader cause any problem in rooting. Thanks.

4.1.2 to custom roms=knox? solved

I just got a note 2 for att, it's on 4.1.2. If i install any custom rom from 4.3 or 4.4, will it update the bootloader in turn installing knox?

Yes. ..If you take an "official"...OTA...you will get Knox. ..
But if you are rooting 4.1.2...and using a custom recovery. ..then you are free to flash the roms found in the development section. ..(no knox)...g

Nope. U only get Knox bootloader from official 4.3 OTA. U can flash any ROM and still stay on your 4.1.2 bootloader.
P.S. just don't flash ROMs which are Knox Dependent. I've read somewhere about a ROM that's Knox dependent.

4.3 update.

I have a note 2 I am running 4.4.2 Probam and love it. I just bought another note 2 for my wife and its 4.1.2. I plan on rooting but probably no custom ROMs. Just debloating on my own. Should I update to 4.3 or stay at where I am?
I have never updated my bootloader and use 4.3 touchwiz ROMs fine with devil kernel. What's my best move from some expertise experience. Not a nooby but not a developer. Thanks

It honestly depends on ur plans for that phone. If u never plan on rooting it I would definitely update to 4.3 using the ota. But that's just a personal opinion. If ur planning on rooting I wouldn't update to 4.3 using the ATT ota. If u update to ota 4.3 anytime u use odin it will trip the Knox counter. And then chance for a warranty replacement if u need it is slim to none. If ur planning on rooting there a a few really solid TW 4.3 roms out there with no worries about Knox.

4.1.2 is solid. Since it's your wife's phone, personal experience allows me to say leave it be. Lord help me if Candy Crush doesn't work.....
But you have an option.
A time saver to get to 4.3 and rooted on your current bootloader would be this.,,

AT&T UCUBMK6 i317 *Odexed* Stock ODIN Note 2
It's already rooted, all you have to do is debloat with Titanium BU or whatever.
From the thread -----> If you *are not* running Official 4.3 (MK6) or newer bootloader: After flashing one of the firmware packages above (the Stock ODIN) flash the bootloader package below in Odin to get wifi working (sorry, no option available for CWM/TWRP). I've included the Odin executable just after if needed.
Bootloader needs to be flashed only once. See post #2 for information on how to check what version of bootloader you have installed.
This is what you will flash:
AT&T i317 ODIN 4.3 UCUBMJ4 (Leak) Bootloader & TZ (AT&T Note 2 ONLY)
This bootloader will not trip Knox.

Thanks. Not worried about warranties. I rooted it at 4.1.2. I'd I update OTA to 4.3 am I still able to put a custom recovery on it? Kinda confused if the 4.3 update locks the bootloader and lastly wasn't the at&t s4 bootloader able to be unlocked when it first came out? Soon after a OTA broke the root. If so then why wouldn't a brand new one out of box be able to have bootloader unlocked just as the phones come with the same firmware version and not updated until bought. Just wondering.

Check this here, it should answer your questions.
I am not too sure about the S4.
I recently got a refurbished Note 2 that came with the 4.3 firmware (my original note 2 broke), MK6 booloader. According to this link, If your phone is running the MK6 bootloader, It is not possible AS OF NOW to revert to the previous bootloader MJ4. You can put CWM recovery and custom roms on your 4.3 build but I don't think they are too stable as of now. I have not tried it yet.

I have at&t note 2 and never updated to 4.3 like I said before but when I flashed a 4.3 tw ROM WiFi wouldnt work like you said. Instead of doing the Odin bootloader thing I just flashed the devel kernel and everything went good. WiFi works flawless. Devil kernel works on toichwiz and aosp. My question is would it be better to do that and leave the bootloader alone?

The note 2 I got last Friday is 4.1.2. The only reason I didn't get the note 3 is this whole bootloader crap. T-Mobile is really starting to look good from here

To not confuse. I have had my note 2. Just got my wife the other one. I don't think I am going to update it at all. Just to make sure I rooted hers with framaroot and stopped any ota 4.3 from slipping by.

One last question. Not sure if we already touched this or not. On your at&t 4.3 note 2 can you put a custom recovery cwm?

How did you flash the devils kernel ? ODIN ?
And the answer is yes you can.

Is 4.4.2 Bootloader Locked?

I don't care about Tripping knox, or voiding any warranty.
Outside of that, is the 4.4.2 bootloader locked? Meaning, can I easily flash a custom recovery TWRP or CWM? Are you able to downgrade the firmware at any point, or are you locked in doing that?
I had an AT&T S4 but got tired of it's locked bootloader, so I sold it and I am back on my S3 for now. I was considering picking up a new T-mobile s4 and then unlocking it for AT&T, but I wanted to be sure it was an unlocked bootloader on 4.4.2 before I did.
Thanks.

It's unlocked, the only thing you can't do is downgrade the firmware but you can still flash 4.2.2 or 4.3 ROMs

Okay, sounds great. I don't have any particular need to go back to something lower than 4.4.2, so that is really no big deal. I am just trying to get myself educated on where the phone is limited.
Thanks.
EDIT: So your are saying that I would not be able to downgrade to an official 4.3 firmware for example via odin, but I could use twrp to flash a custom 4.3 based rom. Just making sure I understand you correctly.

4.3 i believe still works as it holds the newer bootloader. But 4.2 you will need to use a ROM zip to install that one. If you try in Odin it fails due to signature headers not matching in the bootloader.

I read somewhere that flashing even an untouched Samsung 4.4.2 firmware though Odin would trip Knox. Can anyone confirm that??

The Knox flag is only tripped when you flash a non-stock Recovery. If you only flash stock ROMs, it will not trip Knox.
However, some Root methods install a non-stock Recovery and this will trip the flag.

Thanks man. I don't know to much about Knox because I have an MDK Verizon s4. I'm researching this for my girl. Thanks for clarifying. So it sounds like towel root with no recovery is a safe plan. Thanks again.

Let us know how it worked. I rooted before TowelRoot was available, and wanted a non-stock Recovery so was fine with the Knox flag being set.
