Basebands - Galaxy S 4 Q&A, Help & Troubleshooting

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

Modem-related questions

Hi

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.

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#*#*

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!

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 :/

Hey have you figured this out yet... I'm in sort of same situation I have a Sm-g900t but it's running a G900M stock rom, so I need to know how to keep my bootloader & modem and just flash a stock unbranded rom. I know I can flash custom roms through recovery but I want a stock to fall back on

It's not clear what you hope to do. What you wrote is that you wanted to change you ROM to W8 while retaining your TMobile baseband. And your photo shows that you did just that.
But reading between the lines suggests that you were surprised to see that the baseband hadn't changed and are actually seeking the opposite of what you asked. You need to clarify your intent.
The result that you have is the expected situation. The baseband normally won't change, nor does it represent a problem. Your phone should work fine with the W8 ROM paired with the original baseband.
Aside from the fact that there is usually no need to change the baseband, how easy it is to do so depends on the carrier and how they sign their firmware. Odin won't change the baseband if the carrier decided to omit the requisite permission to do so. TMobile modems are invariably compatible with Canadian (W8) carriers, so pragmaticaly the easiest way to update a 900T modem, if you have a rationale for doing so, is to install a TMobile update. Then put the W8 ROM on top of that if you so wish.

Can I flash SM-G900F firmware on an SM-G900I?

Hi,
I have an SM-G900I and was wondering if anyone knows if I can flash SM-G900F firmware on it? Will it change the model number as well?
Also, does anyone know the difference between the 2 models apart from one being an Asian model and one being European?
Nope. You can't flash different models firmware, because it'll brick your device...
Isn't it effectively the same phone though?

Sure you can flash the 900F firmware. It isn't recommended and may "brick" (damage) your phone, making it as useful as a brick. You'd already know this if you had read any of the existing threads on the subject. But you can try anyway if you really want to. If you do, at least make the effort to locate the proper 900F PIT file and flash it concurrently. Your phone still won't work properly afterwards, but using the PIT file will make it less likely that you brick it due to partition corruption.
If you just want to change the displayed model number, you can do that by editing the build.prop file. The main difference between the two models is that they are intended for use in different regions and with different carriers and have different firmware. Therefore each will support different frequency bands.
Unfortunately you didn't tell us why you want to do this. If you are trying to use your phone on a different carrier that uses different frequencies, then trying to flash a 900F firmware won't do that. If you are looking for some 900F specific apps or features, you can probably do that by installing a 900F based custom ROM instead.

Yes flash another firmware will change the model number accordingly

Thanks for your comprehensive response!
The main reason for wanting to flash the SM-G900F firmware is because it seems like a more mainline branch and DBT/BTU will probably get more OTA frequent updates than XSA and i think issues would get resolved quicker in that branch...

You could do that.. but NFC and sundry other features will fail on you. And any update involving the bootloader won't work for you. And probably ditto for any radio (modem) updates.
Your best bet to do what you want in my opinion is to install a 900F based custom ROM e.g. the Alliance ROM. The active custom ROM developers are proactive in updates and supporting their ROMs and would see the best result by you.
This approach would leave you with your stock 900l bootloader and radio. And 900F ROM, with updates for the ROM maintained by the ROM developer.

When you flash the new firmware, the build.prop is replaced by a new one and the model number will be changed accordingly.
You can also manually change the model number by editing the build.prop file (ro.product.model), as fffft already pointed out.

[Q] Carrier Specific ROMs

Hey Guys!
I have a question regarding stock roms. I've been looking at SamMobile for an official release of Lollipop here in Philippines, the only download I can see is for a local carrier Globe. Will it cause problems if I flash this on my international N9005?
I also want to ask the same question for an S4 I9505, but it's the other way around; the phone is from Globe, network locked, and I am thinking of flashing an international version ROM. Will this cause problems? I know this isn't the right forum but just in case someone would like to answer.
Thank you!

1. Yes, you will have problems with the radios. It's not importat where you live that what CSC have your device. Install this APP and look for your CSC. Go to Sammobile.com, look for your csc, download and flash the latest stock rom for your device via ODIN. (Pic attached)
2. Regarding GT-i9505: Yes, it will cause lose of signal. The best you can do is unlock it by IMEI.

I flashed a rom from Brazil. Everything works great it's just that the bloatware included is annoying. I figured the best option to flasha ROM from my country but the only one with a Lollipop ROM is carrier specific.
Samsung allows users to use roms from their own region interchangeably. In most cases, even globally.
I've never encountered issues with radio or signal loss when flashing different providers and countries in my own region, and I've had thousands of people flash and use all sort of different EU firmwares. (you can find the region on the sticker on the box.)
(US users have different devices with real carrier locks, so those are excluded.)
