Help with gs3 root

Hey guys. This may have been asked already but i am coming from verizons gs4. and over there you can oly get custom recovery if youre on mdk bootloader.
I just bought this phone for my brother and it came with 4.12 (MG2)
I see everywhere that people were able to get 4.3. i tried updating through phone and through kies and says its up to date. so now my question i guess is what bootloader do i need to be on or what 4.x.x do i need to be on in order to root and get custom recovery to flash custom roms?
any help will be greatly appreciated.

I recommend not updating to stock 4.3 ROM as this will install Knox and you will have a non-downgradeable bootloader. You can use Odin to flash Philz Touch which is based on CWM. From there, you can flash custom ROMs.
Some ROMs require a 4.3 bootloader, but these would tend to be based on the stock Samsung ROM. I am running the latest Validus 4.4.2 on a stock Bell 4.1.2 bootloader without a problem.

Oh ok. Well I just succesfully rotted and installed latest touch cwm.
so if I stay on 4.1.2 I can basically flash any kitkat roms? Because I dont want to install a tw rom.
So another question what are some good 4.4 kk roms? As in stable for daily use that I could flash

Most kitkat ROMs will work with a 4.1.2 bootloader based on my experience.
I like the Ground Zero ROMs and use them on the s3, Moto Atrix HD, and Nexus 4.

Most likely you are trying to flash a 4.4.2 KitKat Tmobile custom rom coming from
the NB4 4.3 stock Jellybean rom.
If that's the case then you need to Odin flash the official stock kitkat 4.4.2
rom before you can flash any of the 4.4.2 kitkat custom roms.
You can download the official 4.4.2 kitkat stock Odin flash rom from
http://SamMobile.com After flashing you will need to root the phone
again and flash a custom recovery like TWRP or CWM.
Once that's done you will have no problems flashing the 4.4.2 kitkat custom roms.
Good luck!

[Q]Need clarification for rooted rogers note 2, android 4.4

Hello, I recently just updated my Rogers SGH-i317M to 4.3, which then downloaded a system update which put it at 4.4. I was running Jedi X20, which is based on 4.1.2, when I first tried updating, I flashed the "4.3param_tz" file in odin, and was left with an error screen saying I need to recover using Kies, so I downloaded the official release, flashed via odin, and thats how I got to where I am now. I want to try the "Ditto Note 3" rom, "Sky Note Air 4.3", "Mean Bean" and "Beanstalk". My main question is, can I just start flashing these roms like I was before on 4.1.2, or do I need to use the specific kernel listed on their page? Before you needed a specific kernel to run a touchwiz rom or an aosp rom, so is it still the same? Or can I use my stock 4.4 kernel and try both aosp and tw roms now? If so could you point out the kernels I would need? And educate me on anything else I should know about before flashing 4.3 and 4.4 roms, (I'm not worried about warranty), this would be greatly appreciated. Thanks for your time in reading this and helping me out, much appreciated!!

Regardless of where u are, I'd Odin to Rogers stock KK 4.4.2. Then Odin Twrp recovery, boot into twrp recovery and flash SU v.1.99. Finally choose your rom and flash away. This way you are on the lastest KK 4.4.2 Bootloader and KK Modem/Baseband.

I did all that except flash SU 1.99, so I tried flashing SKynote Air and it didnt work, upon restarting my phone it said no os is available. So I tried restoring from the backup I made of the official 4.4.2 Samsung rom in twrp, didn't work. Tried Odin, didn't work. Then I tried flashing the Skynote rom again and it worked. So I'm afraid of flashing any other roms now.

[Q] From custom JB ROM to KitKat, what steps needed?

Its been so long since I installed a custom JB rom I can't see how to update to a custom 4.4.4 rom.
I've got KYRILLOSv8 and baseband rom XXMF1 and don't know the steps to take to flash a Carbon KitKat edition. I think I have to use ODIN to flash an official KitKat rom first then follow the instructions for the custom rom, is that correct?
Can I use ODIN to flash official KitKat over the custom KYRILLOSv8 or do I need to go back to official JB rom first?
Its just steps needed to go from JB custom to KK custom I'm unsure about and after a quick procedure guide so as not to end up in a mess. Any help would be appreciated thanks.

It was easier than I thought, flashed the lated JB rom in ODIN then installed custom KK rom and gapps.

Back to 4.3

My SGH-T999 currently has slimkat 4.4.4 I have searched through this thread to see if it possible to go back down to back down to 4.3, however it appears that the because 4.4.4 has new bootloader this cannot be done and could brick the phone due to knox? Can anyone confirm this for me?

Are you looking to flashing the stock full firmware or a custom rom? You only flashed a 4.4.4 ROM not firmware, and there is no official 4.4.4 for any of our S3 variants, only 4.4.2. T999 doesn't even have a 4.4.2 update as of now, so you can go back to 4.3 firmware if you would like

Yes, I'm trying to flash back to the 4.3 stock image. Basically I have rooted, and flashed a custom Rom (slimkat) and I would like to back to the stock experience.
