Update my modem firmware or baseband? - AT&T Samsung Galaxy S6

Hi, I have an at&t S6 but am on T-Mobile. I was wondering of it was possible to flash a modem that would be more compatible with T-Mobile. Currently I'm on at&t's 5.01 stock rom. Could I Odin just the firmware for a different modem?
I ask because at times, signal quality sucks and hope that a modem built for their network will increase signal quality. Yes, I know that T-Mobile's network coverage is a bit shoddy already and that certain bands are locked on this version but maybe there's a creative solution? Thanks!

Modem From Telecom New Zealand ROM

http://forum.xda-developers.com/showthread.php?p=9429663#post9429663
and wondered if someone might be able to pull this modem out so it can be flashed via CWM? I'm sure this will be a good modem but would be good if someone could test it.
I'm using a Captivate on the Telecom New Zealand network which is an 850 3G network.
Does this have hsupa? What is the baseband version on the phone?

Click on features and youll see this:

Well this might work, might not, modem files are funny on the captivate some have call quality problems, some have bluetooth audio quality problems. You should be able to use the bell vibrant jk3 modem which I'm using now on att. Hsupa and works with the captivate bluetooth and clear calls as well.
I'm sure a dev will investigate this one as well shortly. Designgears is usually on to of these things.

US TMobile 4g to UK 3g

Hi,
I've got a TMobile 4g Streak with build 15420.
Question is - can I upgrade to 21700 without any problem?
Thanks.
There's no real difference beyond the fact the EU modem is missing 1700mhz.
As far as the rom is concerned though, it really doesnt care what modem, if any, is installed.

[Q] Differences between GT-I9305 and N/T variants?

I have the GT-I9305N, which apart from the standard 1800 and 2600 MHz bands available on all 3 phones has the 900 MHz band activated in place of the 800 MHz band available on the GT-I9305, whereas the GT-I9305T seemingly has only the 1800 and 2600 MHz bands.
So is the LTE chip in our 3 phones the same chip or are there different variants? And what is the point of the GT-I9305T if the only difference is it has one band fewer than the other two, I mean why not just sell the GT-I9305 in that case? Wouldn't that make more sense out of a manufacturing aspect? (fewer variances means fewer configurations and less work for a manufacturer, I hope this is obvious to people)
I mean unless the point is that the GT-I9305T should only be usable on carriers which have networks with the correct frequency bands supported, making re-sale less likely. That is literally the only possibility I consider likely. What are your thoughts?
Nobody knows anything about this?

Probably there is some legislation about low frequency bands in Australia, I don't know... But AFAIK i9305T was made for Telstra Australia, as i9305N was made for Sweden where Tele2 (COV) and Telenor (Voda) are working at the 900 and 2600 spectrum.

I haven't looked into it but don't really think there is much difference. I have the 9305T which from what I have seen appears to be a Telstra only model as I think both Optus and Vodafone in Australia sell the 9305 (I may be wrong but remember seeing Optus with 9305 not 9305T). I have not tried a 9305N rom but both 9305T and 9305 roms work fine on the 9305 only difference lately is signal strength. Status bar reads one bar less if using a 9305 modem. I am pretty sure the 9305T would have the 900 range active as Telstra use both the 850 and 900 range.
I do remember reading some time ago that Telstra are a bit more picky with testing the phone on making sure the software is more suited to their network and being Australia's largest telco provider I think may have sway over some manufacturers who are willing to make multiple varients to get what they want. Just my thoughts could be wrong

I'm not from Australia, so i cannot say much about your telco providers. But here in Brazil i only saw the GT-I9305T been selling by Claro (wich includes mine). As i could search, Claro works with the 850Mhz (3G) , 1800Mhz (GSM/GPRS/EDGE) and 2600 MHz (4G).
On Brazil - as the site from Claro says - 4G only works yet with the range 2,5GHz - 2,69GHz.
== Sorry the bad english ==
For those that buy a GT-I9305T with Telstra firmware and try and use it on another telco's network, calls and SMS will work but MMS and Data will not due to the CSC.
The solution is to download the stock Australian Firmware and use Odin to flash
For example
PDA: I9305TDVBMB1
CSC: I9305TTXSABMB2
The symptom is the missing H+ etc in the status bar next to the signal strength bars.
My phone is GT-I9305T, will it work the same if I flash the GT-I9305 rom along with RIL + modem from GT-I9305T?
I have a gt-i9305N
I think the N stands for Nordic, I live in Sweden and have Tele2
And I have only flashed the rom. No need to flash your radio if it already works fine.
Flashing CM rom won't touch your radio and rightfully so.

I used a i9305t with stock Telstra firmware on the Optus network for a little while before I rooted it and changed roms. Data worked fine...
Sent from my GT-I9305T using xda app-developers app
I know this thread is old but incase anyone else is wondering. Its the modem thats different, the 9305T runs on Australian frequencies and adds the 850 band which is Telstra NextG network.
Hope this helps.

Yes. just flashed the german 4.3 ROM on my I9305T - even the 4G data worked, but data speeds improved greatly when I flashed my carrier's current baseband/modem.
The hardware in the variants are the same, it is just a carrier/manufacturer agreement to limit non-carrier provided firmware.

I agree fully. I too have a GT-I9305T LTE from Telstra. I had the 4.1.2 firmware running. I too downloaded the latest Jelly Bean 4.3 for GT-I9305 from Germany (I9305XXUEMKC_I9305DBTEMJ4_DBT). I honestly had my concerns. Compatibility for the network being one of them. I did alot of research and decided to take the plunge. All done and I am more than happy with it. The dowload speed jumped from about 6mbps to 60 mbps. Not sure why but I dont really care its faster than broadband that I'm stck with at the mo. Anyway. GT-I9305 firm works fine in a GT-I9305T.

OK, I did a crap load of research on this earlier in the week because I'm in the process of buying a few I930x phones for the family via eBay.
My understanding is that the hardware is identical but the ROMs in use on each version may affect network operability.
The issue gets clouded because data you find here and there on the interwebs tends to have conflicting information about the phone's specs.
Regardless of what specs you read on GSMArena or elsewhere, the ROMS for phones that Telstra and Optus provide are customised for their requirements.
The hardware may be identical to the that described elsewhere on the web, but the software isn't necessarily so. ROMs for the i9305 and the i9305T are also customised by other network providers around the planet, and thus may differ from the vanilla "International" versions.
I'll restrict my reply to LTE (4G) here, as all variants of the i9300 and i9300T appear to be compatible with 850/900/2100 3G UMTS spectrums used by the three Australian networks.
Both Telstra and Optus currently operate 4G on the 1800 spectrum.
However, Optus operates additional 4G on the 2300 spectrum for its "4G Plus" customers - see Optus's notes at optus[dot]com[dot]au/network/mobile/4g
Telstra does not operate on the 2300 spectrum and has no requirement that its handsets operate there. Hence, I would be surprised if Telstra feels any desperate need to incorporate access to the 2300 spectrum in its ROM.
On the other hand, Telstra has "... also been using some 2100MHz spectrum to provide extra capacity on [their] 3G 850MHz network using the latest generation of network radio equipment known as Software Defined Radio. As the number of LTE devices that are capable of LTE2100 increases, [they] can simply change these cells from 3G to 4G-LTE via software. This will help [Telstra] manage 4G capacity until [they] get...new spectrum. See Telstra's notes at exchange[dot]telstra[dot]com[dot]au/2013/05/07/mobile-spectrum-auction-result/.
So, both the i9305 and the i9305T will work on the 1800 spectrum, but the i9305T may or may not work on the 2300 spectrum and the i9305 may or may not work (for 4G) on the 2100 spectrum.
Theoretically, the i9305T is also optimised for the specific band within the 1800 spectrum that it needs to operate on. However, in practice, the handsets are tolerant enough such that this is not an issue.
Handsets provided by Telstra and Optus will definitely work on the relevant spectrums their respective networks utilize. i9305 devices provided by third party providers require investigation on a case by case basis.
However, the situation is about to become more complex.
At last year's ACMA auction both Telstra and Optus bought additional bandwidth in the 700 and 2500 spectrums for expansion of their LTE networks. See Telstra's info here exchange[dot]telstra[dot]com[dot]au/2013/05/07/mobile-spectrum-auction-result/ (again) and ACMA's info here www [dot]acma[dot]gov[dot]au/Industry/Spectrum/Digital-Dividend-700MHz-and-25Gz-Auction/Reallocation/digital-dividend-auction-results.
In the Telstra link provided above, Telstra also says "Firstly we’re seeing new devices that support the LTE900 MHz band (another low frequency band) so we’ll use this in areas where coverage and capacity makes sense. We’ll also deliver Australia’s first LTE-Advanced network and devices using LTE900+1800" and "We’ve also been using some 2100MHz spectrum to provide extra capacity on our 3G 850MHz network using the latest generation of network radio equipment known as Software Defined Radio. As the number of LTE devices that are capable of LTE2100 increases, we can simply change these cells from 3G to 4G-LTE via software. This will help us manage 4G capacity until we get the new spectrum."
So, in the not-too-distant-future, Telstra 4G devices will operate on bands in the 700, 900, 1800, 2500, and possibly 2100 spectrums, whereas Optus 4G devices will operate on bands in the 700, 1800, 2300 and 2500 spectrums,
A summary is here mobilenetworkguide[dot]com[dot]au/australian_mobile_phone_frequencies.html"]here[/URL].
The big question then is how are customers going to get firmware upgrades so that there devices can take advantage of the spectrum changes.
It would be reasonable to assume that Telstra and Optus will provide updates for newer devices they have provided. However, neither will provide firmware updates for devices acquired from elsewhere. Optus ROMs won't take full advantage of Telstra's network, and Telstra ROMs won't take full advantage of Optus's network. Other ROMS may or may not provide access to all the relevant bands,
So, Telstra may provide updates for i9305T units it has provided, and Optus may provide updates for i9300 devices it has provided. In order to receive these updates you will need to be running the appropriate Telstra/Optus Australian ROM on your device.
Devices acquired from 3rd party providers, whether they are i9305T, i9305, or anything else, will probably be left out in the cold.
You could, of course, root your device and load a suitable ROM that way. I could do it, you may be able to do it, but 99.5% of people out there would not be able to do it. And I really couldn't be bothered to do it on multiple handsets.
So for peace of mind, given these imminent changes I'm sticking with Telstra branded i9305Ts. It just seems to be easier that way.
PS to mods. I saw the message "To prevent spam on the XDA forums, ALL new users prevented from posting outside links in their messages, yada yada yada" However, I'm not spamming and the information I have linked to is on-topic, but it is obviously too voluminous to incorporate into the post. Hence I have taken the liberty of modifying the URLs of the links as a compromise, so that they are not hotlinks but people can still find the sources. I don't mean any disrespect. It's just that I went through this exact same process earlier this week, and found the source information to be really helpful

Question, I'm trying to install the 4.3 ROM also, but so far haven't been able to find it available for download. Can you link to where you found it by any chance?
Edit: I was looking for this specific ROM, as others had tried and tested it. I have found other 4.3 ROM's for the I9305, but if anyone has a link to I9305XXUEMKC_I9305DBTEMJ4_DBT that would be nice

[SM-N920C] Possible to flash SM-920G baseband and modem?

Hey guys.
As title says. I bought and SM-N920C whilst in UAE but I live in South America so want to know if possible to flash the SM-N920G region specific modem and base band seeing as I am experiencing reception issues on the phone. I am getting 4g just fine but I am finding that I get poor quality signal. Only two bars most of the time.
I know the South America region specific Note 5 is SM-N920G so I wanted to know if I would be able to flash the modem and baseband from that model onto my SM-N920C?
Would this help improve signal reception?

It's not possible to flash N920G modem and bootloaders on N920C. My best recommendation would be to potentially try other modems and bootloaders for countries that use similar bands to yours. But the problem is still likely to remain as the bands supported by N920C are different to those supported by N920G.

Hey brother,
Thanks for the reply. As far as I understand both the n920c and n920g support LTE bands 1-12 the only differences are above those.
I only use bands 1-7 so given they both use these same bands is it still not possible? Are there any hardware differences or are they the same phone in that respect?
Thanks!

Unfortunately you still cannot flash the modem and bootloaders because partitions sizes are likely to be different and the phone itself will not let you flash them.

SM-N920R4 US Cellular Variant

Hello all.
I would please like to ask if its possible to install a T-Mobile Note 5 rom on this phone so that i can get Nougat and Wireless calling. I read on the S7 threads its possible to switch from an AT&T phone to a T-Mobile rom. I am hopeful we can do the same for the US Cellular variant as its quite slow with updates, im still on MM albeit April 1 security update.
Thanks
No help?
AT&T and T-Mobile are both GSM carriers. US Cellular is CDMA so you would be better off trying to flash a Verizon firmware and I am not even sure you could do that.

i understand that but thats just an LTE band issue. the phone works happily on Tmobile. Its closest relative is a Sprint Note 5 but i dont want to flash Sprint firmware, i want to have Tmobile firmware on it cos im Tmobile.
