I've read everywhere that you need to find a modem that works best for you, which I have... I9300XXBLFB modem covers my geographic region according to Samsung-updates... but does this mean I have to use the LFB RIL as well? Or should i download the latest RIL?

You must be a previous HTC user. So am I. Over here in the Samsung world, you don't ever have to worry about RILs. They are never mentioned anywhere and I've never seen any downloads for them. One less variable to worry about.
Someone has started posting about RILS in the modem thread and supplied a RILS updater .
Must admit never heard of it before last week .

Hi,
If you paid atention to the RIL you can try getril on the Play Store, compatible with our SIII, I use it.
After some tests, for me and it depends of the network operator / country, a matching / dismatching RIL affects the data speed and the quality reception for the same area.
But it needs some long tests for find a good RIL with a good radio (and not obiously the RIL according to the radio), or at least for me.
For example I use actualy the LG6 radio with the XLFB RIL and it works great for me, better than with the corespondant RIL.

Thanks, will give it a try
Interesting, the RIL flashing thing must be more relevant (and necessary at times) on AOSP ROMs. On my S2 and S3, running custom Sammy ROMs no one has ever mentioned anything about flashing RILs. I know in the early stages of CM10 they were having voice issues with some modems, which may have prompted codeworkx to start messing around with the Samsung RILs. This isn't nearly as much of a factor in Sammy ROMs because they usually include a matching modem, and therefore the matching RIL is automatically flashed as part of the ROM.

Sorry if this has been asked, but I have not been able to find a solid answer yet. Can I install " [ROM]UCLC2 Official ICS "Leak" I777 (3-27-12)" on my S2 with the baseband version UCKK6 and be alright? I had an incident where I put a kernel that wiped my wifi capabilities a while back and wasn't sure if it was because it contained a different baseband. I'm not sure on which modems/basebands I should stay away from?
Thanks.

That would seem to be true, since the modem.bin "image" is really just a mini-kernel and real-time OS (ThreadX I believe) loaded by the modem and only talks to Android via the RIL abstraction layer.
But on the Captivate, when using an i9000 ROM (similar to the use of i9100 ROMs here) you actually had to use an i9000 modem too. In fact the rule generally was, the modem had to match the kernel, as we had separate kernels for i9000 and i897 ROMs. This of course opened up many more options since the international variants inevitably have many more modems available. Point is, on the Hummingbird platform, the modem/kernel (and usually ROM) were somehow interdependent on each other. Maybe due to quirks specific to the RIL in each? Or maybe something else? No idea, and not sure that anyone ever bothered to figure it out. (Why people aren't more intrigued about trying to "hack" the modem binary is beyond me. I don't care if my phone violates the law or gives me cancer as long as I get better reception and data speeds... )
Any ideas as to why this wasn't the case with the i777?
In particular on the Captivate, running a mismatched modem would result in voice calls not working properly, though data would usually work, which isn't all that dissimilar from what happens on the i777 with a mismatched modem/kernel/ROM combo.
Just looking for any solution that would let us run i9100 modems on the i777 in particular since there is no proper way to adjust the bands selected by the modem. Aka, that whole stupid RAT restricted bull**** business that AT&T seem to enforce on the UCXXX modems.
Thanks in advance!
And PS, I'm not kernel developer (though I am studied in C/C++), but if you pointed me in the right direction as to where I might be able to find some useful RIL debug output, I'd be willing to pour through some logs looking for anything interesting.

I think that in the case of the I9000 vs. I897, the modem/CPU audio interface may have been entirely controllable by software.
On I9100 vs. I777, there appears to be some hardware in between we don't have control over. As a result:
An I9100 modem on I777 results in no audio regardless of kernel.
An I9100 kernel on I777 results in no audio regardless of modem. I know this end of things - one of the digital I/O channels is set up very differently on I777. Master instead of slave I2S (or was it the other way around?), 16 kHz sample rate instead of 8, and a few other settings are different.
There might be something about that "in between" block we don't know about and can control with the right knowledge, but right now - there's an unknown black box somewhere and it prevents I9100 modem firmwares from providing call audio.
Hello people,
For the past few months I'm having this issue which I find extremely [email protected]!!
Every few minutes, my phones just loses internet connectivity - the 3g signal appears to be normal during all the time, thing is, whenever I try to use any internet application - it just hangs. and then, after a minute or so, connectivity is back(again, for a few minutes).
I have tried flashing so many versions of modems - some improved it a little but most of them didn't help at all, or even made it worse.
Hopefully someone could help me with that as I'm that close to give up on this and buy a new phone.
Thanks in advanced.
Nir.
Which firmware are you running on your phone? What modem do you have right now and where do you live? Do you have problems with all apps that use internet-connection? Do the problems dissapear when you use wifi?
Just some information would be usefull

Yop.. forgot to mention a 'few' things...
Model: GT-I9100
Rom: RootBox V3.8
Kernel: 3.0.31-CM-g7ce58e6
Baseband: I9100DXLPB
Android version: 4.2.2
I live in Israel, bought the phone in Thailand.
I tried flashing all available Israeli modems(from various cell phone providers) - none helped.
Problem disappear when I move to WiFi - as 3g connectivity moves to background...
Thanks.
I assume you've read the Rootbox threads to see if other people experience signalproblems?
Did you compare the connectivity with other roms? Stock-based roms for example...

That seems quite weird.. The only thing I can come up with is 1) a hardware problem, or 2) you live in an area where the signal is crap
Hopefully someone else knows anything.. Good luck.

If you've only tried flashing the modems bundled with stock roms from Israeli carriers, you haven't done nearly enough. There are literally dozens of modems available, you need to start flashing as many as you need to. This isn't going to fix itself magically.

I haven't flashed only Israeli modems but others as well. I've tried around 20 so far...
Question is, which direction should I choose? should I look for Thai modems or IL?
That depends. I know Israeli carriers sold (still sell ?) the I9100T, are you sure you don't have one of these ? If that's the case, I'd be trying modems bundled with roms released by the Australian & NZ carriers which sold the I9100T (I have one), and yes, the Thai ones as well.
If you do have an I9100, then keep trying any/every modem you can get your hands on. If it's not a carrier-side issue, this is really all you can try, unless you want to start messing around with RIL's as well. I've not found any difference in connectivity doing this personally (tho many people have) but if you get to the point of trying every single modem & you're sure it isn't a carrier issue, you might as well try. But I would leave this till last given many people find their connectivity messed up even worse by flashing an incompatible RIL.
I recently had najor problems with gps reception and locking.
I flashed many different roms in trying to solve it.
I searched the forums and saw many suggestions, all of them spoke about tweaking or using a different gps.conf files.
Tried many of them and nothing helped.
Then I flashed a rom that changed the modem also and what do you know, gps was working again. Good reception and fast locking time.
It also was a sammy based rom and not an aosp/aokp/cm rom.
The thing is that I think the modem was the main solution. Maybe the sammy rom helped too since I did get a response from someone saying that there is a piece of software in sammy roms that is needed by the gps and can not be integrated in the aosp aokp cm roms.
Since then I am kind of reluctant to try another rom, maybe an aosp one with this modem and see if the gps works good.
Maybe a group of people can check this, me included, and report thier results with different modems and roms.
Since I use my gps daily it realy was a difficult time for me when I experienced these problems.
So this topic may become a good guide to people with s2 gps problems.
My problematic modem was xms2 while good ones were xlq6, kh3 and xlph. Also on a friend s2 xls8 worked fine.
A good thing will be to include your location as results may vary according to it.
My location is Israel.
Thanks

It's not the modem, GPS has nothing to do with which modem you use.
It's probably more with the fact you went back to a Sammy based rom instead of aosp/aokp/cm

From my experience with embeded modems they usually contains the gps receiver as well, this is why I believe there is a connection but it can be also be related to the rom.
This is why I asked other users to try it out so we can get more statistics on the issue.

I did some testings today and here are my resuls.
It seems tat there ae two problems one is the modem used the other is the rom.
Changing the modem did help a lot on aosp/aokp/cm roms in terms of reception and locking time. It seems though that after dalvik wipe it will take much longer to lock the firsttime, then it is much faster took my device to lock about 17 to 30 seconds while on the first time it took as mch as 2 minutes.
But on these roms it seems that less satellites are viewed and used, they only managed to use 4 or 5 ay most when there where between 7 to 9 satellites visible.
Sammy roms used all or most of the satellites visible, which led to a more accurate locking.
Good modems where KH3, XLPH, XLQ6, XLS8. I believe that KH3 was the best followed by XLPH.
Bad modem XMS2.
ROMS Avatar rom for aosp/aokp/cm based, ROMs4 and vivik for sammy based.
Regards and hope it will be of use for someone.

I believe you have to flash a modem designed for your device specifically.

HI everyone... I have a question:
I have an at&t sgh i717 with a virgin sim (Im outside of the us), and I need to choose a new modem (I think) because currently I have this t989 uvle1 for tmobile that I had to use to unlock my phone. I'm getting three bars in the signal so my question is or are: do I really need to change the modem? Does the signal have to show more bars so that one can be sure that the modem fits the phone? And, a modem has to be chosen depending on your phone and on your location (since I'm in southamerica)? does having a 2.6.3 kernel affect any of this, should I upgrade it?
I hope I'm not asking too much, sorry,
thanks
Wrong forum, belongs here. I've asked mods to move your post, sit tight.
Edit - You mean i777, right ? (I717 is the AT&T Note).

Since you have an i717, normally you would probably want to flash back to an AT&T based modem. However, since you're probably not on AT&T's network, your best bet is to try several modems and see which one works best with the provider in your area. My recommendation is to at least base your tests on signal strength and speed tests.

OK, I'm going to try several because just yesterday I found out that my gps didn't work and I think that's related to not having a suitable modem.
Additionally, I performed a speed test and whereas I get 12 mbps for download in my laptop I got 10 mbps in my phone, not much of a deal though.
Regarding signal, I get from three to four bars which isn't that bad and I've made a couple of calls and everything seems to be fine.
Since the gps thing is a real setback I'll flash another modem but I'm also thinking on upgrading to ics because right know I'm on gingerbread 2.3.6 with 2.6.3 kernel so I wanted to know if It's better to flash the modem before or after upgrading.
Thank you for your answers
You will probably have better luck if you upgrade to an ICS or jelly bean based rom.

The gps not working isn't always antenna issues. You can try to update the gps data file. Go to the market and get a gps fix app. You're looking for an app that will replace your gps configuration file with an updated file.

Thanks, good to know that.. it's just that when I received the phone it was working and based on that and some comments on internet I attributed this error to the switch in modem/baseband/radio...
Anyways, I'm installing a rooted ics rom and I'll come back to comment, hopefully positive things
I don't spend a lot of time in the AT&T thread. Mostly just the general M8 area.
Lately I've noticed what I thought was some worse cellular radio reception.
My baseband is 1.21.2533xxxxxxxx
Had anyone had better success with a different radio. All of my ROMs are Lollipop
I would reccommend only using at&t or dev edition radios, but usually the newest ones available is what everyone uses, I personally am using the newest dev radio right now with no problems with reception

There is no "best radio" for everyone. It depends on lot on the reception in your exact location. But I agree with the above, most folks have better luck using AT&T or US Dev Ed radios on AT&T's network.

Thanks - the worse radio reception is based on nothing but general usage poor reception (which is what I posted in my original question, ie, no mention of battery life, download speed, etc). I have just noticed that after firmware and radio upgrade it just seems like I am having cellular call issues with worse call reception than before. No objective data to present ...
@ZeRo2o9 could you be so kind as to post your current baseband so I can compare
Thanks
I am currently using the 1540.8 firmware package from the thread in the AT&T dev forum, from wonders never cease, it's from the lollipop dev ed firmware with red text removed already I would say for you just to try that, but I also run the Rom that is edited for AT&T, best thing to do is try it and see what works best for your area

I need to take a look at what's in the radio thread. Since the OTA to 4.4.4, my radio has sucked to the highest order. Drops, hangups, complete lost of signal. It's been horrible. Is it possible the changes for VoLTE could be causing this?

Did you try a factory reset (backup any important personal data first)? If not, all bets are off when you OTA. Simply too many variables with pre-existing settings and apps that can conflict with the OTA and cause random and major bugs.
