Hey guys
So here is my problem.
My GPS is really bad at the moment. I just found out its because it's not the best version of the modem that's inside. 20a instead of 21c.
So I would like to flash it into 21c.
Since my phone is not rooted, is that a pb?
If not, can you guys gimme a hand to flash it?
I downloaded a .zip file with the right version of the modem on a different thread. But what do I do with it?
I tried to follow the "go to recovery" as mentioned but I just don't know where to go.
Therefore can I update to 6.0 without losing all my files? And then switch back the modem from 30B (6.0) to 21C ?
Thanks

Hi guys! I have the italian firmware for the i9195, i9195XXUBML4. I have alredy tripped my knox, so i don't care about the warranty...
If i flash the GT-I9195XXUCNH5_R1 deodexed from @ladislav.heller, will i face problem with modem or something else? I already have some experience with my ex s advance and with my current tablet ( tab2) wich are both with cyano, so i can understand something
I cannot try it because if i flash something i want to be sure that it is compatible with my phone, i wouldn't brick it
Sorry for the bad english xD
@Alecotro Before flashing that ROM you must upgrade your modem to cnh5. Links for that modem are on the ROM's thread.
When u download that modem file extract it and flash it with ODIN as PDA / AP. Repeat and verify if your modem changed. Check baseband in settings>about phone for confirmation. Once u are done upgrading the modem u can flash the ROM via custom recovery.
Without modem u will face connectivity issues and force closes. I am using that ROM and it is perfect.

Thank you very much! Will the different modem have problem italian carrier like wind (don't know if you know it)? Cause with my s advance i always had the same baseband whatever the rom i flashed...
And, in the future, if I flash something like cyano, will i have to switch back to my old modem?

No CM is independent from your modem.

Up!
If I flash a firmware different from the ITV one, will it be different with signal of Italian carriers?
New galaxy user, here its a s3 for ATT 4.4.2 i747CUCFNE4. I have rooted using the Cf Auto-Root method.
Along the lines of trying to flash a new task manager apk, (for I had to factory reset my phone because the original task manager was missing) I came across a thread that had s5 apps (settings apk) and tried flashing this apk(don't laugh I know.) Then I couldn't get my phone to boot through the standard setup wizard. So I tried booting into recovery and factory resetting my phone clearing cache, dalvik, and partition.
My biggest problem arose when I chose to format system from ghe recovery.
I know all this can be fixed with odin but I can't find a 4.4.2 os link, I have read I can't simply downgrade my os. A link to a 4.4.2 stock rom thread would be greatly appreciated. I also have the Ktoonsez kernel installed if that makes any difference.
AT&T never released a full 4.4.2 ROM. AT&T released 4.3 and 4.4.2 via OTA updates only.
Since you are on the NE4 bootloader, do not flash anything that will attempt to downgrade the bootloader or the modem. A mismatched modem/bootloader combination may cause other problems.
Have a look here: http://forum.xda-developers.com/showthread.php?t=2789917
Ok I just reviewed your link in your response but just to be clear I'm starting where it says step 3: stock deodex and root and finishing the walkthrough from there?
And also will this reset me to my factory kernel?? Either or it doesnt matter to me I'm still trying to find one that I find suitable.
And I appreciate the speedy response you've been a huge help.
If you just want to get your phone up and running, I would flash Philz and then CM11. Confirm the bootloader and modem then decide if a stock ROM would be best.
I am always paranoid when it comes to flashing bootloaders on the s3 so I prefer to know exactly whan my phone is running.
I have never used the thread I linked because I no longer have an s3 i747m. Infact, I haven't had my s3 for several months.
Ok and my last question is you can flash Philz and CWM 11 through odin?
Nevermind I see it now greatly appreciated
I hope it all goes well. With CM11, you will also need to flash Gapps via CWM as CM11 does not include certain apps such as the Play store.
Now odin wont recoginize or open any of my rom files. Li see the rom im trying to flash by name but when i click open it only opens the next folder instead of initiating the flash. I really just need someone who has a 4.4.2 stock rom in md5 format.(edited or not.)
As a last effort if i get no answer im going to try to downgrade to another os and reupdate to 4.4.2 right after. Ive been searching for days now all i see are guides from how to upgrade to a different os . If it does include 4.4.2 they only posted the update and not the entire rom.
And when i do find someone posting a full rom for 4.4.2 its either not for 747i or its not a md5 file so someone plz help me.

DO NOT downgrade to a bootloader older than your NE4 -- doing so will cause a hard brick.
You did mean i747 instead of 747i, didn't you?
Odin is designed to not flash any stock rom that would install a bootloader than the one on your phone. this is to save you from hard bricking your phone. Since you are on 4.4.2, any stock rom in a .tar.md5 format has an older bootloader than your NE4. As far as I know, the only stock NE4 rom on the forums is in a .zip format for flashing from recovery, it was posted by enewman17. (The thread audit13 linked.) If you tried to flash an older bootloader and baseband package through recovery you will probably hardbrick the phone.
Otherwise, there are roms based on TW in the forums: S3Rx, TMS3KK, Likewise, and others. Some use the stock kernel, others give you an option from their Aroma install. The iBubbler's kernel in a couple of these roms is reported to be excellent.
I'm guessing you pulled your S5 apk from either the S3Rx or Likewise thread.
I appreciate everyones feedback and guideance. Yeah I meant i747. It gets pretty easy to misread something when all you've been doing was researching roms and guides. And now its back to researching and finding one of the roms you mentioned. Much appreciated everyone I hope u all have a blessed day..
i know this a zip , but maybe could find help in the thread.

Hi there,
I installed CM12 and my data goes crazy, so I checked on the modem and it's indian ("DD")... i'm in France. Would anyone be cool enough to tell me what modem I should install and where to get it (warning, CM12 means android 5.1.1) ? I assume it's just something I flash in Philz or through Odin? Thanks very much to anyone who reads this
It's OK, I finally fixed it by flashing MJ9
Hello,
Trying to install the custom ROM cyanogen mod 11.
http://forum.xda-developers.com/showthread.php?t=2682905
First time I ever attempt to flash a custom rom.
In the guide it asks to DL Bootloader & Modem. My baseband is:
I747MVLUFOB3
I can't find any baseband corresponding to this one.
Here I found a firmware that correspond to my base band.
http://www.sammobile.com/firmwares/database/SGH-I747M/
Not sure if it is useful...
Any way to install the custom room??
Cheers

Which variant of the galaxy s3 do you have? You should be able to flash any ROM compatible with your phone using TWRP or Phil touch recovery.
I have the i747m (rogers canada). I have TWRP 2.8.7.0 & rooted with Kingo root. Somehow it was the only way to root it. Tried Towel root & odin but both were doing nothing.
TWRP was installed a long time ago. I recently made an update on kies (what a mistake sign...). I was on 4.4.2 before and after the firmware update on kies.
I got a spare S3 motherboard (with cpu etc.) I might try on that one first but I need to disassemble & assemble everything... not very tempting.
I usually just use odin and http://www.sammobile.com/firmwares/ to start fresh and root again when I want to upgrade bootloader and modems.
As you saw at sammobile, OB3 is the latest official release for the i747. You do not need to do anything to your baseband (modem) to run CM11. You may want to verify that your bootloader (firmware) matches the modem. This can be done from within TWRP. Go to the advanced menu and in the terminal enter
Code:
getprop ro.bootloader
You should get a return ending in OB3.
I suspect the CM 11 updater-script has not been updated to account for the just released OB3 firmware. If that is the case, you could always edit the script in the roms zip file.
@dawgdoc
When I entered the command, it returned me:
I747MVLUFOB3
Secondly, I have not tried to install CM11 (or the newer version CM12?). I do not know if it works. I just want to make sure I can flash and not brick my phone.
My phone is not the d2att (i747), it is d2can (i747m). I believe these two are very similar but enough different to cause problem.
So, can I install CM11 or 12?
You are talking about changing a zip file... The newb I am know how to do that, but what exactly - that he doesn't know. So I would rather not mess with that. I guess TWRP checks if the firmware of the bootloader / modem matches to those from a compatible list and simply updating that list would allow me to install the build?
I was thinking about this ROM:
http://forum.xda-developers.com/galaxy-s3-att/development/unofficial-cyanogenmod-12-t2968854
Don't know the exact difference with the CM12 but it says d2can.
However, the BaNkS GAPPS - GAPPS link does not work... I don't know what that is.

The unofficial CM12 -5.1.1 by @matrixzone is good for the i747M, aka d2can. If you have any doubts, ask on that thread if it is updated to run on OB3? Matrixzone is active on the forums and should respond to your question. Also I just checked the updater-script for the latest CM11 official nightly and it is set up to run on the i747M.
So, either should run with no problems for you.
What is the bootloader and modem version needed and how do I get them without getting a locked bootloader? I'm on i747M with 4.1.1 Stock rom with DLK4 modem and bootloader. There are newer bootloaders and modems that can be flashed through recovery but some people have been getting bricks when messing with bootloader.
THey say to use Official firmwares to have it update the bootloaders but which one is the proper firmware version to get the proper bootloader and modem version to allow DATA 4g LTE after flashing CM12.1 Lollipop rom?

Hi is it recommended for me to update my baseband I747MVLUFOB1 to I747MVLUFOB3? I'm currently using OCT-OS M and I don't know how to extract the modem.bin of the official firmware of samsung. A tutorial for updating it and rooting it again to flash CM 13 will be much appreciated guys.
P.S. Will there be a yellow triangle sign after updating it to latest baseband, if so, how can I remove it?
EDIT: is it okay to choose from any of the region in the list http://samsung-updates.com/device/?id=SGH-I747M? Thanks in Advance
I am not sure that if will make much difference. The fob3 rom update may take care of security issues.
If you are going to run cm13, the simplest way to get there would be to flash back to a stock fob3 rom, flash twrp via Odin, then flash cm13. There is no need to root before flashing twrp since you will be replacing the stock rom with cm13.
why would u do that .. i'm on FNK2 and i flashed all roms including cm13 .. theres no need to upgrade ur baseband .. and if u want to upgrade u have to chose your provider i mean rogers bell ....
The i747m carried by all Canadian carriers have the same hardware which means that a Rogers i747m rom can be flashed to a Telus i747m phone. The only restriction is that the rom being flashed cannot have a bootloader that is older than the phone's current bootloader.
