Modem-related questions - Vibrant General

Hi
I'm running Euphoria RC2 (ICS based as you should know).
Is it safe to flash any modem over it? I live in brazil and i am currently using KB5, and i'd like to know wich modem would be the best one for my area and carrier, how can i decide that?

You can find a bunch of ICS modems here:
http://forum.xda-developers.com/showthread.php?t=1399722
Unfortunately modems are binary-only black boxes, possibly full of spyware, so there is no information that I know of about how they work. The recommendations seem to be generally to just try different ones and see what works for you.
This is assuming Brazil uses the same 3g bands as your phone. If not, I don't think a modem will help.

Hi, Quick Question here.

Ive got a Samsung galaxy tab which has a reference band base version P7500UBKL1
While searching for a custom rom I ran across different versions of the tablet XXLQ8 or XWLP5 or UELPL
My main question is, Could i flash any of these roms and have it working?
If i do flash one of these would i loose the ability to use 3g? or would it just brick it? thank you for the support.

XXLQ8 is for Italy, XWLP5 for Baltic countries and third, I don't know (USA?). I think all of them are working in 7500. While
installing You can select Your native language, and that's all. In certain regions, as in Finland where I'm from the official ICS
is going to come maybe in some months, so nowadays I have installed Toldo's Jellybean ICS v.6 and it's working just great.

Basebands

Hello,
as I am completely new to Samsung, I have got a question regarding the different basebands.
My S4 is running XXUAME2. New custom Roms are using different versions (for example XXUBMF4). and what is a CSC?
I couldn't find information if it is important to stay at the same baseband version, wher the differences between the basebands ar.
Can anybody please explain me?
Thank you!

I would also love to get the answer to this question +1
Thanks
Basebands are the same as the radio. They can improve your signal, and i some cases even affect other things like camera quality.
Newer basebands are nearly always better.
CSC is country code and you should try to find a code with your country
makhakz correct me if im wrong but csc's and modems are two different things altogether. my advice would be to leave csc alone as its allready set for you and just flash a different modem.
some modems may increase speed and connectivity others may improve these.
its a case of trial and error really as to which one works best for you

[Q] Baseband question

Hello everyone
I wanted to ask you a question about my device's baseband.
Currently I'm on CyanogenMod rom version 11, which I installed via the installer (since it looked so fast and easy).
I moved to CM about 2 months ago from the BTU version of baseband I9505XXUEMK8.
I do not have any reception problems but I saw since this baseband version there went out many other versions (including the new baseband version for the leaked Kitkat).
I do not want to have future problems and I feel "guilty" on being on an older baseband version so my question is when do I need to change the baseband version? Only if I have reception problems or in other cases, too? And in which cases?
Thanks in advance
If everything is working fine then there is no need to change. Usually people would change if their network releases a new modem as it's better to be on the recommended modem used in the original firmware by your specific network or if people are having signal issues. All models work regardless of rom. I've flashed many modems and all have worked fine find the right one and stick to it.

So as I said, I'm on I9505XXUEMK8 modem almost 3 months (from the moment it was released for BTU, but I'm from Israel not England).
As far as I understood, I can stay on that rom as long as I don't have any problems right?
Correct. You'll be fine with your current set up.

Reception/Modem/Baseband

Hello,
I recently upgraded from Xperia Arc S to Samsung Galaxy S4 I9505.
I bought my device from Hong Kong, with HK firmware. After I opened the package I put my SIM inside,
the reception was not very good. I was instructed by the company to use GSM only since there is no
LTE network in Israel as of today.
I flashed a couple of ROMs since and today I am on MIUI v5 which is my favorite, the reception remains
the same in all ROMs, quite bad compared to my old Xperia Arc S.
I was wondering about basebands and modems, I have been watching those two names floating around
the forums quite a bit and I never got around to playing with those.
So my questions are as follows:
1. Is there a different between modem and baseband or are these two just different words that refers to the same thing?
2. Does changing a baseband/modem can help get better reception?
3. If the answer to 2 is yes, which one should I get?
Thanks,
Oded
Yes modem/baseband are the same thing. Go to SamMobile website Google it, then go to the firmware section, choose the S4 find your carrier and see the latest rom for your carrier in the file name will be some letters and numbers like XXNA5 etc. This will give you a base to start with. Or tell me your operator and I can take a look.

Thanks for the quick reply. How do I find out which firmware I need to download? Israel is not in the list. My carrier is called Orange. http://orange.co.il/
behind the battery it says:
GT-I9505
SSN: -I9505GSMH
RATED
Made by...
Imei...
S/N...
EDIT:
You didn't answer if the incorrect baseband can cause bad reception... it sounds to me like it does but I just want to make sure.
I also noticed that when I reboot my device it goes back to WCDMA only automatically so everytime I reboot/power off I need to reset it to GSM only using *#*#4636#*#*
BUMP

1. Same thing .
2. Yes.
3. You can check it from here that Base from your country/Provider . And you can download it from here
The problem is that Israel is not on that list, I think because we don't have LTE network and my device is LTE.
My carrier is using GSM network only.
Israel don't sell the I9505 officially, they have the I9500 available from your carriers.
Looking at the I9500 with Orange the latest I9500 modem is: I9500JKUEMJ9
Obviously do not flash the I9500 modem but you can try XXUEMJ9 from the I9505 instead.
From here: http://forum.xda-developers.com/showthread.php?t=2192025
Download the modem and flash via Odin. You can any of the I9505 modems. Just try until you get a good one, and as for LTE it doesn't matter in the network settings you will obviously be choosing 3G option instead.

I see, well, it didn't work, I flashed about 7 different modems and I still get bad reception indoors and good reception outdoors.
I will try to test other SIMs of other carriers on this device to see if reception improves.
Thank you very much for you help!
4.4.2
Anyone knows which modems can I flash in a stock i9505 4.4.2 rom?

Any modem you want to flash. But try the 4.4.2 versions.

Really? I ask this question because when flashing stock 4.4.2 I had to flash a specific modem otherwise it wouldn't work. If I flash another modem different from FNA5 won't it cause problems in the ROM?

Depends what bootloader your on, I'm assuming your on the new bootloader so you need to flash both the LTE and GSM modems. I'm on a GE 4.4.2 rom and old bootloader running on an older modem and not got any issues. Try it and see what happens you can always flash another after or go back to a 4.4.2 modem.

OK thanks a bunch. If not too much trouble can you point me to a list of the modems you speak of? And is there anywhere where it's detailed how to flash both modems? When I changed modem in the previous ROM's I only had to flash one.

This thread has all the info you need:
http://forum.xda-developers.com/showthread.php?t=2192025
A small tip to whom ever is reading this: If you have reception problems just go to someone with the same phone model and just write down the information in about phone section such as: baseband, core, build etc so you know which one works 100% if your phone is the same model.
Anyways, nikzDHD, I9505XXUEML6_MODEM worked best, I flashed 90% of the modems... took me forever :/

Canadian i337m compatible marshmallow roms?

Ok I'm just a little confused.
Canadian i337m compatible marshmallow roms?
Are they jflteatt jfltexx i9505 or something else or all of the above.
(I'm running wamanlite 4.4.2 9505 rom now on my jfltecan I don't think there are any good links for it left, and when I flash a new one there will be no going back)
I know there are others confused out there as well..
If you are using marshmallow and you have flashed the rom to your Canadian s4 and all is working great.
Please post a link to that rom here
If you needed some other kernel or file to flash in to make it work
Please post that info with links also.
Thanks for any info you can provide.
(And bite me Samsung att and others for locking so many U.S. carrier boot loaders which has reduced development)
The s4 should work with the 9505, jflteatt, and jfltexx ROMs; however, editing the updater script may be required to get the ROM to install.
Hahaha - you will likely get yelled at to use the search bar and to read the stickies with these sorts of questions, but I was a noob once too, so here's an olive branch. (that being said, please do use these in the future!)
Your i337m will be cross-compatible with ALL GS4 devices (at least to my knowledge). I've had one now for a little over 4 months and have explored most of the options available to the Canadian variant. I have run everything from 4.2.2 to 5.1.1 on my device successfully, but you will have the most luck where the developer indicates that the build is for jflte devices in general, not one in particular.
Furthermore, the GS4 or ANY device sporting a Qualcomm chipset can use a modified modem file to access WCDMA/HSPA bands (ie. WIND, or T-Mobile).
Again, the search bar is your friend here! Also try Google, or Duckduckgo (google will tailor your results, sometimes in a way which will actually hinder your search).
If all else fails, send me a PM and I will assist you wherever possible.
Best of luck!

Just wondering what modem to use. Do I use the latest modem for I337M or can I use modem for I9505. I live in Canada and have always used the modems for the I337M model. The latest modem is PA1, I think for the I9505.
Hey tvsite,
Modems for this phone in Canada puzzled me for quite some time, however, this is what I did to make things work.
--> Downgraded from 5.1.1 CM 12.1 Optimized via odin using "I337MVLUAMDJ_I337MOYAAMDJ_VMC.zip" (http://www.sammobile.com/firmwares/download/14412/I337MVLUAMDJ_I337MOYAAMDJ_VMC/)to net me 4.2.2 (note: your wifi or calling WILL NOT WORK).
You may have even better luck using the SaskTel firmware at this point, although I have not tried it yet. (http://www.sammobile.com/firmwares/download/14418/I337MVLUAMDJ_I337MOYAAMDJ_BWA/)
--> Do the AWS mod, unlocking etc.
--> Upgraded to 4.4.1 using "I337MVLUFNC1_880525_REV06_user_low_ship_MULTI.tar"
https://mega.co.nz/#!h8pTnCZS!t2-PiSb5W9ZyNp7fct7WD_Pg_dnc-eZqtMvpsuKv_9Q
--> I forget what modem I was on at this point, however, after letting OTA do its thing, I wound up at 5.0.1, OH1 modem, and AWS still enabled.
Good luck!

I flashed the OK1 modem which is posted, here, which is for the I337M model. I believe this is country code Mexico. This modem is working fine. Have you tried flashing a I9505 modem using Odin. I tried and it said "failed", so I may have answered my own question---that you cannot flash modems over different model numbers even though its the same phone, ie. S4
