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!

4.4.2
Anyone knows which modems can I flash in a stock i9505 4.4.2 rom?

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 :/

[Q] Can I flash G900F modem on G900W8 and how?

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.

Samsung note 4 not getting anything more than 2G

Hey all im totally new to this and i apologise if this has been covered. I had a samsung galaxy note 4 and my darling kids thought it would be an epic idea to stick things inside the charge port totally ruining it and making the phone unchargable. So i contacted samsung repair center and was quoted a ridiculous price to repair and i just bout a new one to only find that its not an australian version i have a sm-n910k and my original one is a sm-n910G what can i do i cant get 3g i cant get lte i can only get 2G and minimal bars of service at that if anyone can help any advice atm is great advice thank you all in advance.

Go to settings/mobile networks and set apn settings manually depends on your sim carrier and country.
Just google your sim carrier apn settings and you will find easily.

I have already done apn settings and still to no avail i cant work this out for the life of me the only thing i keep thinking is that this model may not be compatible with my country as i know the sm-n910g is australia and the sm-n910k is korea i think ive bought myself a dud unless theres something i can do software wise idk any input is great imput though :/

Did you bought a new device, n910k or was it a replacement part? If you're comfortable, you can always change the USB port itself. I've done it for my Note 2 before. The USB port should be just a ribbon cable so you don't have to worry about soldering and stuffs like that. The prices are also way cheaper too.

Apparently the usb port is tricky to replace as its apart of the screen as samsung has told me and its a whole new device its the korean version im not sure what to do as the place i bought it from is a long distance away from where i live and i was wondering if there was a way i could install like the sm-n910G firmware to it. Im at my wits end with this and not sure what to do.

Oh right. I forgot about that. It was a simple plug out and in for my Note 2.
The issue right now is that the n910k, most probably does not support Australia's LTE bands. Hence the reason why you can only connect to 2G. You can check out gsmarena for the supported LTE bands for different models.
You can install a stock Note 4 Exynos firmware from another country with a carrier that uses the same LTE band as your carrier. It should be safe as some members here are able to install different firmwares meant for another device on their device, example N910G on N910F provided the CPU are the same.
Go to SamMobile, and find the firmware for Note 4 and you can see a list of Note 4 firmware available for download. You need to do some leg work though to ensure that the firmware you're flashing is meant for the Exynos version and the modem supports your carrier's LTE band.

No don't install over the n910g over your n910k. N910k is using a different cpu than N910g. N910k uses Samsung's Exynos processor and N910g being a Snapdragon processor. Idk what would happen if you flash a N910G over a n910K but I think it would be considered lucky if your phone would be able to boot up.
Your n910k should be able to run on another firmware meant for an Exynos processor like n910c. I just don't know if, after installing over your 4G would work because of different LTE bands. But this website says there's a chance it might work.
https://www.frequencycheck.com/compatibility/zYzu9/samsung-galaxy-note-4-sm-n910c/australia
Usually in most cases, when a user accidentally installs a firmware meant for another variant, assuming they would get past the samsung boot up scene, they would not be able to get any network connections. This is due to different firmwares having different modem files for the different LTE bands. However if you were to install over a firmware with the same internals as your current device and more or less uses around the same LTE bands, it should work.

Here you go. It's every firmware ever listed. You need to create an account before downloading though and the download takes forever. You can install the firmware when your phone is in download mode using Odin via your computer.

You can try a random one. Preferably one without a telco. Example, N910C and not N910C (telco name). It shouldn't matter much as the difference would be that the one with a telco would come preinstall with the telco apps. Also, preferably from a English speaking country because usually the language would be based on country.
I would recommend you to download the original firmware for the n910k in case if this fails, you would be able to fall back to the original firmware.

it's not just that. I also have a problem receiving 3g and 4g networks and it's not due to the CSC, it is a weird hardware problem that makes the phone not refresh/search for network normally.
I've never found as solution to this problem, not even with people who run repair shops and I can't take it to samsung as it has the knox void.

The u firmware is what you want. Just download the latest one... maybe pl2? It will unlock all radio bands. You may have to sim unlock it too. Root is unstable and still won't give you the all of the bands. The hardware is there, but the software controls them.
