Hi,
I have the International version of the Samsung Galaxy S III I9300. The baseband that I am using is I9300UBLF2. I was wondering if there is a new modem version I could try to help improve my reception and data issues. I know that I have to root my phone to install a new modem. But can I keep my stock rom or do I need to install a custom rom? How would I install a new modem version for my phone? Thanks
easiest way is to install a custom Tom like omega, then choose the modem from the built in app inside omega..
are you on at&t? even if you switch to the best modem available, your reception, and internet will still suck. I hate my sgs3, I wish I got the American version, good luck to you

You dont need to do anything but install a different modem from the modem thread .See the sticky top of this page .
A custom rom is not needed and will void warranty .

[REF] Galaxy S3 Modem / Radio Collection (I9300 & I9300T ONLY) CWM & Odin Flashable
Hi. I have 2 australian galaxy s3. First one is on 4.1.2 TDUELL2 and the second one is on 4.0.4 TDUBLH1. I want to root both of them. The first one after getting updated to 4.1.2 wifi stopped working but i found a fix installing the wifi folder from 4.1.1 version. To that I need root though. So any help on how am I gonna root them both? Cause I couldn't sort it out my self.

What model number are the phones I9300 / I9305?
they are i9300t
I managed to root both of them. I know have a major problem. 1 of them had a problem with wifi. It couldnt connect. I read about a solution by copying the wifi folder from version 4.1.1. Tried that. It worked for once but after reboot it stopped. And now I can't even turn on the wifi. It gets stuck on Turning on... Do i have to reflash the rom again and if so how will i do that? It was stock rom on stock kernel. Only rooted. gt i9300t moder and build DUELL2.
Also can i flash a rom with different build over that? For example XXEMC2 that i have on my Greek galaxy s3?
I9300T rooting is the same as I9300 rooting, follow the guides of CF-Root 6.4 or CF-Autoroot. (I got a T model myself)
You can flash any I9300 rom also on the T model, therefore root is not 100% necessary. Full wipes are recommended for flashing different versions though.

just saw it .
For wifi, try a stock ROM (flash it new incl. wipes etc.), or try a different kernel, whereas the stock kernel should always work.

you can find (unrooted) stock roms for instance on sammobile.com or (rooted) stock roms here on XDA in the General section.
Easiest way to flash them is via Mobile Odin (gives you the option to keep root) or Odin (you will loose root but you can flash CF afterwards manually).
And yes you can flash any build that is made for the I9300/I9300T.
The only difference between both models is the frequency of the baseband (the T model is more optimized for 850mhz) whereas you even can use modems of the I9300 on the I9300T.

What do you mean by modems? Soz if I sound noob but I am new to Galasy s3. My previous android was ideos x5 and i had a miui rom on it.
The phone will be used in greece. Do you suggest me flashing the XXEMC2 rom that i have on my Greek S3 atm? Is there any chance of bricking it if i flash that rom on it?

There is a difference between the ROM's firmware (basically your OS, e.g. XXEMC2) and the modem (basically the part which gives you the connection to the next mobile tower and is managing the frequencies, e.g. DUELL2).
It does not matter that much what ROM firmware you use as they are nearly identical in each country (here and there dif. apps due to providers) but more that you use a modem that delivers in the country you are in. Hence, I would first try the modems of your region (you can find a list of all modems in the General section's modem collection).
Regarding the risk of bricking: there is always a risk, no one can guarantee you anything , whereas if you follow the guides you should be fine.

Ok. Here is the deal. My greek galaxy s3 which i recently updated is XXEMC2. The galaxy s3 with the wifi problem is DUELL2 bought in australia from a friend but will be sent to greece for my brother. So i should flash XXEMC2 on it? I just download XXEMC2 from sammobile and flash it with odin? It doesn't matter that the XXEMC2 is for i9300 as fas as I understood from what u said. right?

correct, you can use the I9300 versions of any rom for the I9300T as well.

Ok. So the CSC numbers that are different on lets say the DUELL2 and the XXEMC2 are not something to bother me right? I just download the XXEMC2 rom and flash it on the DUELL2 S3 and then I just will root it. right? Will the phone become i9300 after that procedure? or stay i9300t? So I know which file i should use to root it.
Soz for too many questions but the phone is not mine and I need to be sure for the procedure.

The firmware code (XXEMC2) should not be of concern.
The modem code (DUELL2) should be of concern IF you experience bad performance in the region you are. If so, flash a different modem and try it.
The phone will be an I9300T whereas in the menus it might tell you I9300, anyway there is no difference in the files to use.
For rooting, follow the guide, you can use CF-Root 6.4 (if you want a custom recovery) or CF-Autoroot (if you want to use stock recovery).

Thanks a lot mate. This helped a lot. I decided to go with the 4.1.1 version of its current region. Later if we see that it doesnt perform well here in greece we will flash the xxemc2 rom.
Ok i downloaded the rom from sammobile and the file name is this I9300TDUDLK1_I9300ZZZLK1_VAU.zip but i get an error message that says cannot open. file unknown or damaged :/ Why is that? Is this file meant to be named as md5?

To flash a rom via odin you need the md5 file, correct. Hence unzip or if you cannot maybe the download is corrupt?

They are one and the same. HTC we call it radio. Samsung call it modem. Modem is what it is called in Odin so that is what they go with.

Yes, just make sure the modem is for your device.
I was using the S2 with Jelly Bean. I found the phone to heat up very quickly around the camera lens and top of the phone rather than when running on Ginger Bread. I then installed the Resurrection Remix Custom ROM v5.1.3 with KitKat 4.4.2.
But the heating problem is still there. Checking online I found out that the modem was the problem.I found the KH3 modem was the best for the Galaxy S2. I was wondering if installing the KH3 modem was appropriate on Custom ROM or can modems be installed only on Custom ROM???
If it can be installed can anyone guide me how ... BTW I am using the phone in India ...
Please reply the overheating problem is driving me nuts.
Attatched is a screenshot showing my phone information.
You question is a bit confused (because you haven't taken the time to learn 'the basics' like 95% of people who come here), but the answer is yes. Modems are interchangeable between Android versions on the S2 & not dependent on same; I.E you can flash a modem that was bundled with stock rom that was a different Android version to the one you're currently running (whether stock or custom, makes no difference).
As to how to flash a modem....C'mon....
This is absolute basics, you should know this stuff back to front inside out if you're flashing custom roms.
In other words, search.

Usually a modem file size should not exceed 10 MB. You can even flash the modem via cwm. On xda you can find links for such files.

That's not required. Just keep a flashable file of your current modem, just in case you want to revert. I mean, download it and keep it on your phone.
For India, ddls9 also works quite well. I have seen good results on xxls8 too.

I am not very sure about that. My guess is that it doesn't backup your modem with the rom backup.
Hi Guys,
I thought of creating an official Modem list for the Samsung Galaxy Note 3 Neo N7505 Modems only for KitKat 4.4.2
I will be adding all the modems available in Modem.bin .
What is a modem?
Modem/Radio/Baseband is all the same thing and can be seen by going to Settings - About device - Baseband version. It's basically a driver which receives and sends Mobile Network signals as well as handling switching between GPRS, 3G, HSDPA etc....... (but not WiFi connection, that and switchover between Mobile Network and WiFi is handled by the kernel). Reasoning as to why Modem has no influence on WiFi can be found in this post by Entropy
Why?
Sometimes some custom Roms come with modems for various regions. If your modem is designed for different regions than yours then the chances are that it will sometime not work with optimal network performance.
You should look into changing your modem if you are experiencing the following :
Poor 3G speeds
Very fast battery drain whilst on 3G
Poor call reception
How to check:
Settings >> About device >> Baseband version
How to flash the Modem:
Open Odin and click on CP button the select Modem.bin file and make sure everything is unchecked just AutoReboot then press start and your device will reboot with the new Modem
---------------------------------------------------------------------------------------
Modem List:
N7505XXUCNG2 (Middle East & Europe & South East Europe & Nordic countries)
N7505XXUCNL1 (Hungary & Romania & Portugal & Bulgaria & Slovakia & Baltic)
N7505XXUCNK1 (New Zealand )
Odin Download:
Odin3_v3.09
Odin3_v3.10.6
Correct the links setting...Now they are working
good work, I will try XSG I hope it solve my signal issue.
Thanks
N7505XXUCNK1 added & Odin Links
if someone put stock rom for example Hungary COA1 rom with CNL1 baseband version, can then put with Odin CNG2 modem driver for South East Europe. Is there any differents?

It depends on which country he live, maybe he will get better signal for network or worse signal.
If you have any problem with signal or wifi just try another modem.

On settings---about phone---Baseband to know which modem you use,
then you can try another modem and if you want to back to the original modem just download it from here.
I have the modem firmware N7505XXUCNG2 Italian released in October.
I have problems when switching from 4g to 3g for blocks.
In your modem bin above downloadable up is possible to date than the one I use? or should try the other modem?
Then I wanted to know if I make the flash konox goes to 1?
to restore just redo flash firmware or old modem?

You should try another Modem, try this one N7505XXUCNL1
to restore just flash the old modem.
I don't think it will trip Knox because you flash something official not modify, but I'm not sure!
Also Italian ver has old kernel you can flash latest one 14jan2015 it's more smooth&good battery...
but flashing kernel will trip Knox because you will use custom recovery

with odin 3.0.9 I have to select the CP and then I have to do the flash file modem.bin or do I create a file .tar.md5 (that include only modem.bin file) and then flash?
I ask because I had found a guide where it was indicated to create a file that .tar.md5 is the same type of file that the offical firmware

For battery you must notice if there is any issue,
for signal it depends in your area and how it was before.
you must choose what the best modem for you.

I don't understand which modem you try, new zealand or Romanian?
also try another modem to see from where the problem..
just put the modem.bin in CP section and open download mode in your mobile and flash it..
don't change the name of the modem keep it ( modem.bin ) .
