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.

I got to 4.3 with root injected in stock. I now have the MJC bootloader, of course. Are all the other ROMs w/4.4.x compatible ? Thinking of moving to Cyanogenmod, specifically.

Yes all the custom AOSP roms should be fine. CM too will be ok to go.
Word of caution. Make sure your custom recovery is up to date. Otherwise you will face a lot of issues trying to flash CM or other roms.
For the past couple of weeks in have been trying to install a custom rom so I could enable bluetooth tethering for galaxy gear. My tmobile note 3 is rooted in follow every step perfectly, however, after rooting in use Odin to install custom recover after that is done in have my rom on my dad card and boot into recovery when flashing the rom the phone gets sent into reboot loop. If anyone can assist me to either install a custom rom to enable bluetooth tethering or some other way of enabling it would be much appreciated.

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!

Will try this as soon as I am home. I'm am currently on android 4.4.2 if that provides more information.
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.
I figure instead of pulling my hair out for three days wading through various methods and likely brick, I'd swallow my pride and ask.
Here's where I'm at: I rooted and flashed Carbon rom way back when, everything was working alright, but with time, things are slowly starting to come apart. Yesterday, it's come to the point it can't be ignored. My nightly is ridiculously out of date, but I just haven't wanted to mess with it anymore. I'm about ready to get a new phone and I want everything back to fresh stock to give to a family member. I don't know where to start and what instructions are applicable or out of date. Model: I747, Android version: 4.4.2
I think I'm done experimenting with the rooting business, it's been a ride. If I could get some clear instructions on getting this phone back to stock, I'd be eternally grateful.
Help me xda community, you're my only hope.
What bootloader is on your phone? This is important to know before trying to get back to a stock ATT ROM.

Hey there, thanks for replying! Bootloader says I747UCUEMJB.
Since you are on an mjb bootloader, that means you had the ATT stock 4.3 ROM on the phone.
Unfortunately, ATT never realased a stock 4.3 ROM or 4.4.2 ROM. These were only available via OTA.
There was a thread where a stock mjb ROM was compiled for flashing in Odin, but for some members, the flash resulted in a bricked phone.
I had a feeling that might be the case. What are my options here?
I would install a custom recovery and flash a custom rom. There are custom ROMs based on stock Samsung ROMs.

This is the way to go. Since you most likely already have a custom recovery (assumed since you are running Carbon but verify first though), then it is just a matter of getting a new ROM. There are several custom TW ROMs based on 4.3 MJB. If you really want KK, you can flash the NE4 bootloader and modem along with a custom NE4 TW KK ROM. Please keep in mind that with both MJB and NE4 (KK) if you try to revert bootloaders, you will brick.
I am personally running S3RX 4.3 and have few to no issues other than what most people experience on stock anyway. Just have not had the time to move forward to KK as of yet.

Okay, so the bootloader is 4.3, but the Android version in settings says 4.4.2, how does that fit together? Just trying to understand what all this works.
Recovery is currently ClockworkMod. Since I'm planning on giving it to family, I'd like something that is as stable as possible, nothing fancy needed. What ROM would fulfill those needs?

Sounds like you are running a custom KK ROM in order to be using the 4.3 bootloader. A stock KK ATT ROM will not run on a 4.3 bootloader.
Before flashing to a custom KK ROM, make sure you are running the latest CWM. Carbon is a good ROM and should have reached a milestone build.

You are running the official 4.3 bootloader but an AOSP custom ROM. In the case of AOSP ROMs you can typically do this. As mention by audit13, if it was a custom ROM based off TW AT&T stock, you would only be able to run a modified TW 4.3 ROM.
Ive been searching for awhile now but at work is my only time to do so and time is limited.. I am searching for a rom to run with ucdmg2 bootloader. I'm not really feeling up to updating the bootloader using odin.

Do you have a custom recovery installed?
You didn't say, but I can infer that you have an i747 and not an i747M based on the MG2 bootloader.
Without a custom recovery you are stuck using Odin to get a custom recovery in order to flash anything other than a stock rom. There are recovery flashable bootloader and modem files for 4.3 and newer bootloaders and modems.
With the 4.1.2 bootlaoder and modem you could run Jellybean roms from CM ( CM10.x ) or those based on CM or AOSP. There may be a few AOSP bassed on KitKat you could use, but it would probably be a version that is more than a year and a half old. Anything newer will need a 4.4.2 bootloader.
