The thing is if i flash any kernel like custom or other than stock default kernel. I get emergency calls only. It does detects my carrier but no signals. Signals only work with stock rom which came with my cell. Even if i flash other stock firmware, no signals there as well. I noticed the problem is in the kernels.
Any one knows what is the issue ? Model is G950N LUC.
TIA.

yeah maybe. IMEI is ok. signals wokring fine with rom came with it. SD1 PIE.
Have you tried flashing kernel of other S8 variants?
Maybe your model is not exactly G950N?
Just to make sure, try of othe variants.
And probably you know that older operating systems may have problems cause of modem version, right?

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!

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 :/
I've been having a problem on my S5 where the data symbol is stuck on 4G and doesn't show anything else. It might be a baseband/modem error since I'm using a Canadian model in Cyprus. Can I use the modem from the Cyprus G900F firmware and flash it on my G900W8? Also can someone explain how I could do that so that I don't screw it up, if it is possible?
!
RE UP!
Same pb...
To flash a modem you need a .bin file and odin.
Clear your delvik/cache,
put your phone in download mode,
load phone with the .bin file and flash it.
I also am having data issues with all custom ROM's. If it's not one thing it's another. Canadian phones always get left in the dust it seems.

Probably not. You neglected to tell us what your W8 baseband and firmware are, which is rather crucial information. Making it impossible to give you a definitive answer. In most cases Odin will refuse to allow the change.
That isn't really an issue most of the time. There should be a variety of W8 modems for you to choose from if you want to change your modem.

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.
I have downloaded a latest stock Rom from sammobiles and flashed it using Odin.
After flashing everything works fine except Sim card. phone detects the Sim card and shows the signals also. and when I make a call on my number, I can hear the tone like call is receiving at other end but phones does not ring.
My IMEI number has changed to something like this 004451121002 .
I don't have the backup of EFS partition either.
I had same problem on my Galaxy s3 few months back and solved it by flashing patched kernel and patched modem.
not been able to find any patched modem for galaxy s4.
Please help to solve the problem.

Seem like a modem bootloader mismatch.....

Why are you trying to do this?
If you are trying to change the radio bands (like enable new or different LTE bands) just changing the ROM or modems doesn't work, it is embedded deeper in the system.

They are different HARDWARE versions. Different RADIO hardware to be more precise. This action is very likely to result in the radio not working anymore, and you might be left wit a small tablet, that can't make phone calls or connect to cellular data...
Thanks for your information.
There's no specific firmware for each variant. All firmware are universal, so any would adapt to your hardware (NFC, Compass, TV).
So, flashing any firmware will work on any potter
And yeah, model, and radios are on other partitions, so, they won't change on fastboot, or through TWRP

Is this confirmed?
If so, what are the partitions where model and radios are stored (and other model specific stuff)? Are there any other partitions that you should never flash with a copy of another model?
