Need clarifications. - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

Hi everyone!
My gf's GS3 is running CM11 but she runs across various issues in every custom ROM I flash onto her phone so I decided I should just flash stock 4.4.2. I have heard that in mobile Odin I should make sure that the modem or bootloader does not downgrade. I remember that I did flash the I747MVLUEMK5 bootloader and the I747MUMUEND3 modem. Is it safe to say that I can use mobile odin to flash stock 4.4.2 as well as the bootloader and modem without having the fear that it will downgrade one of those? I am thinking this because I flashed those files BEFORE kitkat was released, which has to mean that the 4.4.2 bootloader and modem are newer. Sorry if I'm not clear or that I repeat myself a lot I just try to spit all the information I have because the last thing I'd want is a bricked device.
Thanks Everyone!!!!

Only flash 4.4.2 with mobile odin if you have already fully updated to 4.4.2! It is not capable of flashing mist of the base firmware, including the bootloader. But it does flash the modem, and if you get a 4.4.2 modem on 4.3 firmware/bootloaders,...permanent brick!

What if I don't use mobile odin? By using regular odin can I just ignore all of this and flash 4.4.2? Can PC Odin flash the base firmware and bootloader?

Yes regular Odin will flash everything. After that it'll be safe to use mobile Odin.

Downgrade

My S3 has android 4.3. I'm aware you cannot flash via Odin and downgrade the firmware to a earlier firmware such as 4.0.4. But, would I be able to flash a rom based on 4.0.4.?
Should be able to, as long as its not firmware with Odin

[Q] FNE4 update clarification

ok so i know there are several threads about it but i want it to be clear for me and anyone else that has questions.... i know i posted multiple times but those threads are wanting custom recoveries...
i have the MJB firmware and am wanting to update to the FNE4 firmware....What zip package can be used on the E3 aka stock recovery and stock rom without any custom flashing at all.
i don't want to flash a custom recovery due to warranty.....so which zip floating around can update the phone...
i tried the ota and it failed for unknown reasons multiple times and would just like to flash in recovery....
The only ota that's flashable from stock recovery is going to be identical to the one that failed when you tried to use the software update.
Odin flash 4.3 firmware, factory reset and try again.
OK but is there one that's flashable is my question?

Yes there's a thread in general. Title starts with [Download] I think.
Li know and you have several files up also there is the op so which is flashable with full stock

The one in the OP.
OK thank you very much doc....sorry for the hassle....I'm sure others will benefit from it as well.....thanks again

Not a problem! Better safe than sorry! I know it can get confusing with so much different information in each thread!
I was able to restore to 4.3 MJA and then use the OTA download (renamed to update.zip) from the other thread here and used stock recovery to update.
Just a note: Once you update you can downgrade to 4.3 but you need to use the NE4 modem from here on out. Older modem firmware will result in the device getting no signal.

so restoring mjb on top of fne4 WONT result in a brick?
Sent from my ATT Samsung Galaxy SIII using TapaTalk
I Odin'd 4.3 on top of NE4 (with NE4 bootloader and NE4 modem). Did not brick.
The only issue I had was that I need NE4 modem to get a signal on the NE4 bootloader (bootloader won't downgrade)
Unfortunately I didn't fine an NE4 modem zip around here yet so I updated back to NE4 to get the new modem and my signal. Rooted NE4 /w towelroot and then installed a rom of my choice.
So now I have the NE4 bootloader + modem and a kitkat rom of my choice.

Would my baseband version still be NF1 if...

Okay, so if I Odin the NF1 firmware and then reroot and install a custom recovery and then restore a nandroid backup of CM11(from NB4 baseband) would I still have NF1 baseband version or would flashing the nandroid cause a soft brick?

You can only update the modem with Odin. Flashing your nandroid zip will not affect it any which way.
I have been running CM11 for a month now, and just flashed the NF1 modem separately through Odin last night - didn't have to backup anything and I am now on the NF1 baseband.

I just downloaded the .tar.md5 for the modem, and used Triangle Away to reset my flash counter so Odin would properly flash it.

Thank you for your help!
You said download triangle away so Odin will flash correctly. You do this before flashing the modem? I am researching this since I am still on Nb4 and would like to update modem. I've never updated a modem. I'm on aosp ROM 4.4.4 Nb4 I really want NF1 but nervous about Odin

Yeah, you run triangle away, then reboot into download mode and flash just the modem file with Odin.
Piece of cake, nothing to be scared of.

Install Bell Rom on AT&T S3

Hey Guys,
I am Canadian, and I would like to install a stock bell rom on my AT&T S3.
Is this possible? I haven't found anything concrete on this subject.
The bell rom has next to no bloatware.
You can install the ROM but not the bootloader as cross-flashing the bootloader could brick your phone. You also need to make sure the modem is firmware compatible with the ATT bootloader.
Alternatively, you could root your ATT s3 and freeze or remove bloatware yourself.

Will using the firmware from sam mobile replace the bootloader?

If you flash it with desktop Odin, yes. If you use mobile Odin, no. You'll still have to make sure the modem is compatible with the bootloader.
If using mobile odin, just make sure you de-select modem and recovery. Never use a modem not meant for your device. Too risky.
I wanna do the same on my girlfriend's phone. So basically if I use Desktop Odin (using a firmware from sammobile) I don't have to worry about bootloader? Also, doesn't the firmware flash modem also? Why should I be concerned about it?

Do not use desktop Odin to flash any i747m from sammobile.com onto an i747. This will probably brick your phone.
You need to use mobile Odin and make sure you are not flashing an i747m bootloader or i747m modem.

You need to make sure that Odin does not attempt to downgrade the bootloader if the phone has a 4.3 or newer bootloader. Also, a 4.4 modem on a 4.3 bootloader can cause a hard brick.

I remember updating my girlfriend's bootloader but all this was before the official kitkat update. So I can safely flash bootloader and modem from MobileODIN since I know they won't be downgraded?
No! You cannot update firmware with mobile Odin! Only use it to flash firmware you've already updated to.
If you have the I747m, download the firmware you want from sammobile and flash with regular Odin. This will fully update everything to 4.4.2.
I think there may have been confusion because you said you wanted to do the same thing as the op, who wanted to flash i747m firmware onto an i747. But later you implied you have an i747m, correct? If so! Just flash the correct firmware for your device with Odin.
If that is not correct, please restate exactly what it is you want to do.

I have a SGH-I747M from Bell. All I want is flash stock 4.4.2. I was previously on stock 4.3 and I installed the I747MVLUEMK5 bootloader which is the newest bootloader for my device in @dstruct2k thread and then installed various kitkat ROMs with a custom recovery. I also installed the I747MUMUEND modem afterwards which is also the newest in his thread but I don't think either thread are maintained anymore. So if I want to fully return to stock, I just take the appropriate file from sammobile and flash via Odin and NOT mobile odin right? The bootloader and modem is included in the file I download from sammobile?

Yes. Just flash the firmware you get from http://sammobile.com/firmwares with regular PC Odin. It includes bootloader, modem, system and more.

I am using Odin 3.09 and I see AP and BL buttons. I know I have to click AP but do I also have to click BL to make it flash the bootloader? Or will AP suffice for everything? Do I have to check bootloader update?
Just AP. Its the exact same procedure as before except you put the firmware in AP. You only need the other options in certain circumstances.

I flashed CM11 and heard it use a different type of partition. Would it be a good idea to check repartition? Also, is it 100℅ compatible with SGH-I747M? It isn't included in supported devices for some reason.
Tbh, I'm not sure on that. I don't use cm so I'm not very familiar with it. You shouldn't need to use repartition though. But if going between cm and touchwiz you will have to factory reset or it'll hang on boot.

[Q] Update Baseband - From M919Uvufnk2 To M919Uvufoh3

Hi,
Am on CM12.1, T-Mobile Galaxy S4 SGH-M919, Rooted, Android 5.1.1
How i can update the Baseband - From M919Uvufnk2 To M919Uvufoh3 using TWRP?
You can't. You have to use Odin.

Ok, i can use ODIN. But from where i can find the baseband for rooted custom ROM (CM) SGH-M919?
My method...Backup your current rom. Odin the oh3 stock release, odin cf root, odin twrp, backup the new stock rom, restore prior backup.

Hmmm...thats what i am actually thinking as of now....but looking for easy alternative like if we get the flashable zip or something of this baseband i can just flash it without taking backup of ROM and reinstall the ROM etc.....
But am looking for a site where i can download these basebands....
i take it you are trying to update the modem/baseband ihere you go. Must be done thru odin.
http://forum.xda-developers.com/galaxy-s4-tmobile/general/foh3-modem-bin-mdl-bootloader-t3191094
IMPORTANT: DO NOT CHANGE THE BOOTLOADER unless u KNOW EXACLY what you are doing...changing bootloader to the wrong bootloader will brick your device and some modem packages conatin bootloader. so make sure that you are getting a ODIN file that only contains the modems and no bootloader!
if you wish to properly update the bootlaoder and baseband properly ....just ODIN the OFFICIAL samsung release for your device and then re-root and reinstall recovery and then your rom.

Perfect....I will use this one....
And on S4 you don't even need to root before flashing TWRP and your ROM of choice. Just double flash the stock release with ODIN, let it boot up and make sure all is well, go into Camera to let it see if it needs a firmware update (happens automatically first time you run stock camera app), and when satisfied your phone is good, go into download mode, take TWRP + whatever else you want.
