Hi all i need some quick clarification,
1) I am full aware that if you purchased a Note 3 on 4.3 and you updated to stock via either OTA, Kies or Odin the bootloader is upgraded and you cannot downgrade to 4.3 stock.
2) So my question is if you are stock 4.4 and install root, install custom recovery, Can you still downgrade to a 4.3 rom via custom recovery? or will it not allow me to downgrade at all?
3) Finally You can't downgrade to a 4.3 bootloader correct?
1) correct
2) 4.3 kernels do not boot with the 4.4 bootloader, so no
3) correct

I've got a Galaxy S3 I747 it is currently running 4.1.1, I747UCDLK3 Baseband. I'm not exactly a noob when it comes to flashing and rooting, I know my way around CWM and Odin pretty well. But I have a few questions on this 4.3 OTA. (I am a forum noob)
-Will I still be able to root? (I heard CF works for it)
-Can I install CWM? (Is the Bootloader locked??)
-Will I be be able to I flash other roms than the 4.3 TW like CM11Snapshot? (Is the bootloader locked?)
-What the h*ll is knox and why should I be worried?
-What is with the boot loader downgrading thing? (Have to do with locked bootloader??)
I AM NOT AT ALL WORRIED ABOUT A FLASH COUNTER OR VOIDING A WARRANTY I AM NOT ON A CONTRACT . I JUST DO NO WANT TO HARD BRICK MY PHONE.
If you take the OTA 4.3 update, it will install Knox and the 4.3 bootloader.
The 4.3 bootloader cannot be downgraded and attempts to do so will probably brick the phone.
You can root the stock 4.3 ROM with auto root but Knox may interfere with the process of cause issues after the fact.
You can still install CWM. I rrefer Philz Touch which is CWM-based.over TWRP.
So can I still flash roms?

Yes, you can flash ROMs. Is your phone unlocked? Since you're on 4.1.1 stock, you can unlock it for free.
Personally, I avoided the 4.3 update because it installs knox and the 4.3 bootloader which can cause problems when using Odin to get back to stock.
I have a Canadian version of the s3 and I'm able to run KK ROMs with a stock 4.1.2 bootloader.

Unlocked as in Bootloader? Yeah I've been able to flash roms via CWM and Odin on 4.1.1 and as in Carrier unlocked? Yes I use Straight Talk on this ATT S3
If I got the 4.3OTA I wouldn't need Odin to go back stock if I flashed a ROM would I? I could just make a back up via CWM then restore later if I wanted right rather than using ODIN?
See I can't use KK roms because I have the 4.1.1 BL so is there a way I can upgrade my boot loader to the 4.1.2 version??
Would I lose my carrier unlock if I upgraded to 4.3 or if I upgrade my bootloader??
I suggest downloading a ROM you want to try, then unzip the ROM and look at the updater script to see which bootloaders are supported. The updater-script file is located in \META-INF\com\google\android\updater-script. You can use a text editor to open the updater-script file.
The first few lines will list the bootloaders that are supported. I run Validus which is a KK ROM using a stock 4.1.2 i747m bootloader.
Do you know about this > "If I got the 4.3OTA I wouldn't need Odin to go back stock if I flashed a ROM would I? I could just make a back up via CWM then restore later if I wanted right rather than using ODIN?"
Also couldn't I just upgrade my Bootloader and Modem from here?

I feel like if I upgrade my boot loader then I won't have to worry about restrictions.
Would I lose my carrier unlock if I upgraded to 4.3 or if I upgrade just my bootloader??
I ended up flashing the MG2 Modem and Bootloader, I'm good now, also if I want 4.3 I saw loserskater has a leak version that will be good and wont not let me downgrade my bootloader.
I have a stock, but rooted, AT&T Galaxy S3 4.1.1 -I747UCDLK3- with ClockworkMod Recovery v6.0.3.1 and would like to upgrade to 4.3. After reading the posts regarding updating I'm a littler confused. I was wondering 1) can the the bootloader be updated with CWM or does it have to be Odin? 2) Is there a specific order that the updtaes need to be done in (For example does the bootloader have to be updated before the ROM. 3) any tips would be appriciated
Any particular reason you want to update the bootloader? Is it to install custom ROMs or modem?
I'm running a 4.1.2 bootloader on an i747m with a kit kat ROM.

Every thing I've read so far says the bootloader has to be updated. I was hoping to keep the stock AT&T ROM and just root it to remove the bloatware. only upgrading for Gear compatibility.
Just upgrade bootloader to mj2, baseband to mjb. You'll be fine long as it's a AT&T i747.

Hello guys,
i'm selling my note 7105 cause i bought OPPO find 7..
here i've a 4.4.2 slimkat rom and i'd like to give it to a friend but with stock rom ( he doesn't play with roms..)
now.. i've read here and there and it's not possible to go back on 4.3 ? is there anyt STABLE (real stable ) custom rom then?
i've read that 4.4.2 official is going to be out soon so this might " save " me !
is there any way to downgrade from 4.4.2 to 4.3?
is this Ditto DN3 v4 RC2 worth to try ?
should i install some earlier bootlader if i decide to get back on stock rom?
thanks for all info
What bootloader do you have? If you went from 4.1.2 to slimkat then you should be able to flash any stock rom. The problem is going back to 4.1.2 with the 4.3 bootloader. If you install dn3 you will either have to flash stock 4.3 first or use agni/devil kernel to get wifi.

lol.. don't laugh...
i thought that being on 4.4.2 implies i've that bootloader
i tried to find the version on recovery and system info but,...??
where can i find the info abou tmy booloader? i know it sounds noob ... have patience
thanks
Something like this should tell you
https://play.google.com/store/apps/details?id=com.app.info
AFAIK you can't flash bootloader through recovery so if you were on 4.1.2 when you flashed slimkat you will still be on that bootloader. You should be able to flash any stock through odin if you are on 4.1.2 but if you were on
4.3 you might not be able to flash 4.1.2. If you do flash 4.3 with odin you will get knox

i installed that app and at OPERATING SYSTEM info i get:
OS NAME Kit Kat
Os Version 4.4.2
Boot Loader Version N7105XXDMC3
.... ???
I'm pretty sure dmc3 is 4.1.2 so you should be able to flash anything. I'd flash the stock 4.1.2 for your country with odin run triangle away then unroot and everything will be stock

i have stock 4.4.2 NF2 bootloader , what i need to do for change it to 4.3 ?
and is there any way to unlock hidden languages in 4.4.2 ?
Any attempt to downgrade the bootloader will cause a brick. You can, however, flash a 4.3 rom via custom recovery it will run on your current bootloader. Wifi may not work without using ktoonsez kernel though.

I had to update to ND3 Kitkat bootloader in order to install Dr ketan's 4.4.2 V12 Rom. I still find my old 4.1.2 is much more faster and stable so I wanted to flash stock firmware but I couldn't because of the bootloader. So my question is, is it possible to downgrade the bootloader so I can use 4.1.2 again, flash mj5? If not are there things that I could try? Will there be a modified kitkat bootloader than I can install so I can downgrade?
Thanks

Bootloader can't be downgraded. Flashing older bootloader might brick your phone.
With Mobile Odin Pro some people have successfully downgraded to 4.1.2, but bootloader remains intact.

Doing it with software you may need hundreds of dollars worth of JTAG equipment with no guaranteed result. The cheapest and the most direct way is to have a repair shop to swap out the phone's EMMC, which should be under $100. Specifically state you want 4.1.2 and tell them NOT to upgrade the bootloader or ROM to 4.3 or later.
