hi.
and thanks.
I have tried a few 4.4.2 ROMS and they all loaded on my 4.1.2 bootloader so I would assume they would load on your phone's newer bootloader.
If you're not sure, you can look at the ROM's updater script to make sure.

I don't recall which bootloader I had but I never had 4.3 on my phone; therefore, I never had Knox. I was able to load 4.4.2 ROMs with the stock 4.1.2 bootloader.
I know my bootloader is older than 4.3 because I was able to flash a stock 4.1.1 ROM onto my 4.1.2 ROM using desktop Odin. I unlocked my phone while on 4.1.1 and flashed back to stock 4.1.2. The stock ROMs from samfirmware include bootloaders and modems.

I am thinking to flash a 4.4 ROM on my S3 I747M. The only thing I am worried about the bootloader. If I flash the latest boot loader can I downgrade it?
Here a scenario
I am on 4.4 kitkat,with the latest bootloader,and I decide to go back to 4.2.2 with the latest bootloader. Is it possible to do that?

What carrier do you use? If AT&T is it the MJB bootloader.
You can check what bootloader you having using this - https://play.google.com/store/apps/details?id=org.freeandroidtools.root_checker
If you are on AT&T with the MJB bootloader you CANNOT downgrade the bootloader. It will brick the phone. My guess is that you could possible run a 4.2.2 ROM with the MJB bootloader. I have run 4.3 and 4.4 on the MG2 bootloader with no problem but haven't tried to run a 4.2.2 on the MJB bootloader. As long as the 4.2.2 ROM doesn't flash a bootloader, I would try it. But that's me. Just back sure to have a current backup. If there are any doubts about the 4.2.2 ROM flashing a bootloader, don't do it if on MJB.

most 4.3 aosp roms can run on the mjb bootloader but you have to modify the updater script to include it. but what the post says above if you try to downgrade the bootloader from mj2 ATT then it will brick the device
I have the MVLDLK4 bootloader. The only thing I am worried about is that there might be a few errors while using the ROM. I have tried about 3-4 4.2.2 ROMS but there is always 1 or 2 errors eg. Wifi does not work. Since there is only a few roms on 4.4+, i am worried I wont get a stable rom with minor error.
Cause If I update and the rom has errors, I have no backup rom.
re 7100 bootloaders
(please forgive my lack of knowledge)
i am on phoenix 17 rom currently, bootloader MJ5 (no knox as far as i understand. later bootloaders ie MK4 are knoxed IIRC)
am I understanding correctly that custom roms do not install bootloaders (ie 4.3 roms or 4.4 based on stock or leaked stock)?
and that is why it is possible to still revert backwards if one has a non knoxed BL?
do stock roms install bootloaders (via kies or odin)?
so if for some reason i installed a stock 4.3 i would then be stuck with a knoxed bootloader?
thanks for the info

-Custom Roms does NOT include bootloaders(as far as I know). I'm still in MJ5 BL even after installing DN3 4 Kitkat.
-Yup, i believe you can still revert back if you want to, as long as the bootloader does NOT have knox.
-It depends with what version you will install. Be informed by the "bootloader version" of the 4.3 stock rom that you will install(visible in sammobile). As long as the included bootloader is lower than MJ5(and NOT MK4 onwards) everything will be fine, I hope.
Hope I help. ^.^

where is bootloader version listed in sammobile details i see PDA CSC MODEM
also are any stock sammy roms available without bootloader (new ones)
if not is there a way to install a stock rom without the newer bootloader (can the necessary files EXCEPT the bootloader be extracted out of the .tar files and somehow be installed
thanks
Hey guys
I installed a nightly of CM11 a while ago and it broke my LTE. The consensus is that you need to install a stock-based ROM, then flash back to CM11 to get LTE working again.
I have flashed an MK5 modem, but am unsure of my bootloader compatibility with the current TouchWiz ROM's out there.
I am on the MF1 bootloader (Canadian phone). Do I need to upgrade/downgrade my bootloader to install any of these TW ROM's? Or can I just flash between TW and CM11 to my heart's consent?
The ROM's say you must be running a 4.3 modem and bootloader...but I can't find any info on whether or not MF1 is a 4.3 bootloader or not?
Thanks,
Elliott
Bump
I haven't tried cm11 yet but using c-rom I had these problems. under settings-mobile networks-preferred network type, check to see the right network is selected. If you don't have these options then my apologies.

MF1 is 4.1.2. The latest Canadian bootloader is MK5 (Which you can't downgrade from).

Well usually you need the same modem as your bootloaders. Some of them are really picky so having the MK5 might be why your LTE isn't working.
You can grab the stock ROM in the general stickies and flash it with Odin though (make sure to backup) if flashing a 4.1.2 modem doesn't fix it.

Okay. What I'm most concerned about is flashing a 4.3 TW ROM with the bootloader that I have. Is having a bootloader from 4.1.2 a bad thing? Or can I install all ROM's with MF1?

Only the downgrade is dangerous, you can upgrade without any problem. That being said, you could just flash the stock 4.1.2.
And if I flash a stock based ROM will it upgrade my bootloader to one I won't be able to downgrade from?
Any suggestions for ROM's?

It depends which one you decide to flash. You can flash stock 4.1.2 just like you could flash 4.3 (which you can't downgrade from).
I keep getting errors in Odin and it's likely due to what I'm trying to flash. Is there a 4.4.x official stock rom? Do I have to use 4.3 instead?
What bootloader and baseband is on your phone?
Don't use Odin to try and flash any ROM that attempts to downgrade your bootloader if your bootloader is 4.3 or higher.
I would say whatever is the latest based on the 4.4.3 Pacman rom I've been using. I already wiped the phone so I have no idea what it currently is
if you go to settings > about phone, you can get baseband version.
if you have terminal emulator, type in
getprop ro.bootloader and will give your bootloader version.

If you have the stock 4.1.1 or 4.1.2 bootloader, you could flash the stock 4.1.1 ATT ROM from sammobile.com. If you have the 4.3 or newer bootloader, you cannot flash any stock ROMs from sammobile.com using Odin. You must use a ROM that is designed to be flashed via Odin or a custom recovery.

OK thanks. So that means I have to use someone's rom because I've flashed a rom that is further along in updates than what Samsung / at&t has done?

ROMs dont 'usually' (or ever) include bootloaders. so , if i'm not mistaken it still depends on your bootloader version. i have flashed many KK ROMs on 'old' MJ2 bootloaders.
bootloaders and ROMs are two separate things.

Thanks guys! I ended up figuring out what my bootloader ( MJB ) was by using the terminal window in TWRP. After that I searched for MJB and saw it was based on 4.3. Anyway, I used this as well..

To get back to stock
good job

I went back to stock just by flashing the stock ROM in cwm.
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.
