I run CM 10.1 on my phone, which had original specs: PDA:KG3 / PHONE:KE7 / CSC:KG1 (VNZ). I've been running those CM nightlies since about November 2012 with few problems, updating to new nightlies every few weeks to a month. I'd never flashed new radios - just the CM rom.
Starting a couple of months ago, I began to see a problem where my phone would drop cell service (no bars + empty triangle in the cell signal indicator) and rebooting was the only way to bring the cell signal back. This happened every couple of days, so was bearable. I figured something in the nightlies had caused a weird problem and that the CM devs/community would find and fix this.
After flashing a nightly last week, my phone wouldn't hold cell signal for more than an hour - sometimes not even that. Reboots fixed this but never permanently. I started to read about radios, modems, and RILs. hawkerpaul's post here was a great help. I found that my phone had the original KE7 radio but had a RIL of I9100XXLS8(2) - I presume from the CM rom? I flashed some new radios and have now gone through a series of the (matched) modem + RIL files in hawkerpaul's post above. In most cases I see the following behaviour:
Phone successfully finds network (Vodafone NZ) on boot
Trying to manually select a mobile operator fails (error when searching for networks)
Unable to successfully call out! Dialling stalls, and I can't hang up - only fixed by a reboot
How do I fix this immediate problem of not being able to call/receive calls? Seems like maybe I'm using a radio that doesn't work with Vodafone NZ - but I haven't seen any posts on what DOES work well with that network. I have the modem file to flash the original KE7 back again, but what should I do about the RIL file then? Not sure I have found an RIL for KE7 yet in my travels. Any help would be appreciated - and thanks!
To help me figure out where I went wrong, do the CM builds include the RIL, or is that something that could only get updated somewhere else? I know the rom doesn't change the modem but I suspect that XXLS8(2) RIL had to come from CM.
1) Don't mess with RIL's (You'll make it 'worse').
2) Check stock roms released by your telco. Find out which modems were bundled with those stock roms. Try those modems. If they don't help, look for stock roms released by other carriers which sold the the I9100T world-wide (check Samfirmware). Try the modems bundled with these roms. If they don't help, try any & every modem you can get your hands on.
If you've already flashed RIL's, you may well have created a bigger problem for yourself. You might want to do a clean install of stock as well for good measure if that's the case. The reason I stopped using CM9 (and never bothered with CM10) was similar issues that seem to have gotten introduced with a particular nightly & never went away (a fix was tried which benefited a very few problems who were having RIL problems but created problems for even more people who previously had no problems).

I'm just about at this point. If I reinstall stock, will that reset my modem as well?
Thanks for the help - looks like I did definitely make things worse.
You'll end up with whatever modem is bundled with the stock rom, so probably use the most recent released by your carrier, then you can try other modems released by your carrier as per my PP. The rationale with that is you'd hope your carrier has tested the modems they bundle with their stock roms so they work in most places/at most times with their network. Doing a clean install of stock should fix anything funky messing around with RIL's may have done as well.
If you get no joy from those, proceed as per my PP (You might get other suggestions from other people as well).
Thanks for the help. I was able to flash the latest stock rom, which included baseband I9100XXLS8. This worked fine for making and receiving calls. I lasted a couple of hours with that stock Samsung firmware before I started to get itchy for Android 4.2 again, so I've now rooted and am going to try CM10 again, but at least this time I know not to touch the modem - and I'm confident I can get back to stock again if I have any problems! Many thanks!
Glad you've got connectivity back You can flash modems as much as you want, I'd just be wary of messing with RIL's unless it's as an absolute last resort (I.E you have no connectivity & you've tried every single modem. Too many people try them when their connectivity is fine in the mistaken belief they're going to get 8Mbps instead of 7.8Mbps downloads, I.E it wasn't broke in the first place), even then a clean install of stock & choosing the right modem will often fix the problems.
You're welcome Any dramas post to this thread again & I'm sure someone will help.

Hi and thanks in advance. I have a galaxy i9100 which shows the following information: PDA: i9100xwlsd - Phone i9100xxls8 - Csc i9100vnzls9. I installed via odin Android version 4.1.2 which made the phone work really well except that it kept dropping network service and signal strength. I replaced the sim which did seem to help but did not fix the problem totally. I also notice that the GPS will not find any satellites and just keeps searching for as long as I would let it. I have read various threads and it appears that this may be a modem problem? I have found that Vodafone NZ has released a modem which is i9100xxls9? Should I flash the modem file only in Odin and do you really think this would fix the problem. How would I flash the modem file. Would I do this through odin? Any help gratefully received.
Yes, first step is definitely to flash the modem which was released by your carrier for your region. If you can find a file which is Odin flashable then yes, try it. However most of the files are for flashing via CWM. Are you rooted? If not they won't work for you, in which case you'll have to search around for an Odin flashable version of LS9.
Just to check, you do have an i9100? Not an i9100t etc? Some variants require different modems.

Thanks for the response. How do I know if a file is odin flashable? How do you flash via cwm (whatever that is). You can see I am a little bit or a lot of a novice on this. The unfortunate thing is I enjoy it. I think the phone is rooted and it says the phone is: Model GT- i9100. The phone was purchased in UAE and I have flashed the android 4.1.2 which was a vodafone NZ system. Everything works fine except the GPS and the phone signal drops out all the time showing no service when there is service? Thanks again for your help on this. I have just found that the phone may not be rooted? I tried to install root manager but it indicated phone was not rooted?
Ok so no offence, you need to do a lot of reading for yourself. Reading is the key to successful (ie without bricking) modification of your phone.
For a start, if you've flashed stock then of course you will not have root. You don't need to have root to flash a modem. Have a look here:
http://forum.xda-developers.com/showthread.php?t=1656005
I'm not saying to flash that modem file. But that's how you do it, now you just need to find your file and flash it.

Hey there!
Before anyone asks, I have done the following.
Searched on google/XDA for solutions
Flashed different ROM's
Changed Kernels
Wiped all cache
Did factory Reset
I am currently having bad network problems with my phone.
I am running JellyBam 6.7.0 with default kernel.
Baseband: XXLQ6
Problem
I constently get No Service or "Emergency Calls only" in areas that I've never had emergency calls in. I am not aware of my old modem or RIL, and so am completely lost of what to go from here as I haven't found posts that could help my issue.
When I reboot my phone, turn airplane mode on, or just randomly it will go into the stage above, to where it will stay without signal for 10 minutes up to days (I've had it go for 2 days with no signal). When I try to search for networks (In places where there is 100% a network) it will say "error searching for network".
I have no idea what to do, and am rather scared. There have been 2 emergency situations to where I needed a phone, and yet mine had no signal.
My second question, is if I manage to get it back to stock ICS (4.0.4) and do all the updates through KIES, will I get the original modem + RIL back as well as the ROM? Or will I still need to flash that myself.
TLDR: If I reset it back completely to stock ICS, will everything that I have done (root, flash modems, flash kernels etc...) be erased.
Thanks so much for reading, I've got so much stress rigt now.
Are you getting no service all the time or only intermittently ? Also, check your IMEI in settings/about phone to see if it's the generic one (0049.....), whatever you do tho don't post your actual IMEI here. Just a yes/know answer to the 'is it the generic one' question will do.
If it's a constant thing, call your carrier to check if it's been IMEI blocked. If it's intermittent, flash a stock ICS rom as you'd suggested. You'll end up with whatever modem/baseband is attached to the rom you flash, and yes, you'll lose root & the kernel you're currently running will be replaced by the stock kernel in the rom you flash.

Yes it's only intermittent, so not a problem with the IMEI.
So if I find, and download stock ICS to bring it to factory it should be fine? If I were to, let's say, flash the ICS onto the phone, is there any way to keep the RIL+ Baseband and flash back JB? Or when flashing JB, will it replace whatever RIL+Baseband is attached with the ROM.
Also, thanks for the quick reply. I was expecting days for a response.
Forget about JB/custom roms/anything else until or unless you get your phone working normally again. Flash an ICS stock rom for your region.
And forget about the current RIL/baseband. It sounds like it may well be the cause of the problems you're having; quite possible if you've been mucking around with different RIL's in particular. Pretty sure I said in my PP that you'll end up with whatever baseband is lumped in with the stock rom you flash.
Actually, you might want to stick with a stock rom specific to your carrier if there is one, at least that way you know the modem/baseband will more than likely have been tested by your carrier & is likely to work well with it unless there are other issues (carrier side connectivity issues or other problems with your phone).
As to whether doing this will fix your issues, no idea. At the moment, and in the absence of any clue as to what's causing your issues, it's the best option you've got. If it doesn't fix the problems, then it's probably a carrier-side issue (possible given it only happens at certain times/in certain locations) or a physical problem with the phone (less likely).

I'm having problems to what official ROM to use from the list.
The only one on the list is Optus, but my phone is with virgin (on the optus network) should that be fine?
The rom is I9100XWLP8
Once again many thanks! I'll update you with the progress.
Yep. Flash the Optus rom given you're effectively using their network & see what happens.

Just downloaded it (Hotfile takes forever) and flashed through odin.
Worked fine after a factory reset. However, Kies won't update my phone.
Network seems to running smooth, so we'll see how it goes. The more things I do, I guess the more things I can rule out.
EDIT:
I updated the phone, and I get the message "Unfortunately, Application installer has stopped". What am I supposed to do?

That didn't work.
Anyhow, I managed to track down a 4.0.4 variant of the ROM I was using, and made sure the CSC, PDA and Baseband all matched up with what Kies wanted, and flashed it. I think the error occured I was trying to update a ROM with the wrong CSC and Baseband to one with the correct ones and Kies didn't like that.
Does anyone have a modem for the Australian S2? Peferebly the DVLS3 modem coz' I'm stuck with a DUKJ1 modem on Jelly bean 4.2.2 and i get no bars in my home, my local mall and only 1 bar MAX in the city. (I live in Melbourne on Vodafone). When i first rooted my phone and flashed Thunderbolt Rom onto my phone, it had the DVLS3 modem on until installed MIUI V.5 then flashed the Siyah kernel V.6beta5. Then I was stuck with the I9100XXMS2 modem. So I flashed the Dorinmax kernel on top of P.A 3.0+ but still had the same modem. So then I flashed back the Thnderbolt ROM V.7 and the DUFK4 modem and did better but only got 1 bar maximum (never went above 2 bars). So I scowered the whole interwebs and found a DUKJ1 modem and flashed that (the most reliable so far) but still got no service in my house, and 1 bar max. So here i am now. Please someone give my the modem so I can flash it via CWM. that would be greatly appreciated. DD ( And sorry if I confuse you or get something wrong because I'm new to this sort of stuff).
P.S: If I can't get the modem, please someone recommend a good, reliable modem to use on the Vodafone network in AUS.
THANKS DD

Try DULP4 from that link Sun posted. I've been using it for ages & it hasn't missed a beat. I'm in Geelong/use Voda & also have fairly average coverage inside at one bar mostly, but at least it's reliable. I can get full coverage immediately outside my back/front door.
Having said that (trying that particular modem/others), we are talking about Vodafone here, and what you're seeing could very easily be just the result of their ****ty network.
Edit - Have you flashed any RIL's by chance ? If you have, and trying modems simply doesn't work, I'd be formatting everything in CWM & doing a clean install of stock via Odin. Then flash whatever rom/kernel you want to use. Flashing RIL's may have done something funky to your connectivity (Have seen it happen). If you haven't flashed any RIL's, disregard this bit & keep trying modems. If you find DULP4 doesn't work, try all the modems released with Voda stock roms. Then try the modems released by other carriers around the world who sold the I9100T (check Samfirmware). If you still have no joy, try every other modem you can get your hands on (there are dozens).
So if at any stage a modem*+ril has been flashed, it's required to nuke (or similar) the current ROM, flash stock, and then start from scratch? Or is it ok to re- root the stock firmware & restore a nandroid? I.e. Will a nandroid restore the ril as well?
I only ask as I found a modem+ril combo on my internal sd card the other day. I may have flashed it when I was starting off & didn't know what I was doing, can't be sure :/
Edit: I know that a nandroid doesn't restore baseband. But I couldn't find anything definitive about whether ril is included in a nandroid.

If I'd flashed a RIL out of desperation at some stage to try and fix poor connectivity (I haven't tho/wouldn't) & still had poor connectivity, yeah, I'd 'nuke' the lot & do a completely fresh install and start again. I wouldn't say it's 'required' tho. That's just me being thorough/methodical.
But if you've flashed one & have no problems with connectivity, no need to. I suggested it to the OP given his connectivity is ****ty thinking he may have flashed one. I've seen people on who have had no problem with connectivity flash RIL's with the promise of/thinking they might get 6.5Mbps download speeds instead of 6Mbps & end up borking their connectivity completely.
As far as I'm concerned, I'd only personally flash a RIL after I've tried every single modem & had no joy. Not sure if the RIL is included in a nandroid. I guess the test would be to flash a RIL, make a nandroid, flash another RIL, restore the nandroid & use GetRIL/similar to check the RIL.
The only problem I have with connectivity is in tapatalk. Usual internet browsing /video streaming are fine, so I guess it's tapatalk.
I've never deliberately flashed a RIL, and don't think I have at all, but I can't be sure. As I'm not having issues I will be content.. Not that I'm getting anything close to 6Mb/s.

I just used '6Mbps' as an example to illustrate the things some people do thinking they can get a 'little bit extra' when there's nothing wrong with what they're already getting
I'm pretty new to the whole root and flash. I did my research watched plenty of videos and went ahead. Managed to root and then flash. I currently have neat rom installed but I'm getting a few issues I can't seem to find info on or to fix. The 2 main things are
1.my phone will only use Internet on the H+ and will no load on anything but this (except wifi). It shows all the signals but whenever I want to load the Internet it flicks to H+ and loads sometimes I may have to retry and load the page if it doesn't switch to H+.
2.ive read to fix this if I type in *#301279# and change some settings. But when I type any code in it says invalid mmi code or connection problem. To fix this I've read it needs to be stock dialler but I assume neutron has the stock dialler.
It's beginning to really irritate me as the data won't work and when I use ttorrent I get really slow speeds because it switches back to H when I exit even tho its still downloading and half the time I can't get the Internet.
My phone was unlocked and I am on 3 network.
Oh and I've tried flashing a different modem and it doesn't help.
This pic is of the firmware etc.
You need to keep flashing modems until you find one that works well for you/with your carriers network (hint: logic says try the modems bundled with stock roms released by your carrier first). Flashing one isn't nearly exhaustive.

The modem I'm using at the moment is one from 3 network from what I'm aware.
Just downloaded a findril app and it says this. Could this be a issue? I'm not to clued up on the ril side . I've just puton a matching rril. Issue not solved.
And that's one modem from one stock rom. First up, you need to try the modems bundled with other stock roms released by your carrier (every modem is different/a Samsung 'black box', and there are dozens & dozens). If you still have no joy, try modems bundled with stock roms released by other carriers in your country. Still no joy, try any/every other modem bundled with stock roms released by other carriers world-wide.
This is not going to be a simple fix, it's going to take trial & error on your part.
I personally wouldn't start messing with RIL's unless I'd tried a couple of dozen modems without success.

Well I after the rail and for some reason it deleted my baseband, so I refreshed the baseband and it said complete but was not on after reboot and I couldn't get a signal thank god for back up.
I don't think it's a signal issue. The issue is the Internet won't load unless it's on H+, before I flashed I never had this issue.
Update, when I changed my ril my dl speed on ttorrent was 1.2mb now I have restored and gone back before the ril change I'll be lucky at getting 200kb dl speed. Does that show that my ril and baseband do not match and is causing the issue.
I've read several threads in xda about a Galaxy S2 from Australia working in Europe and vice versa however I haven't seen any mention of whether a stock firmware for the S2 designed for Europe will work on my Australian Galaxy S2.
Can someone clarify that for me please? I don't want to go flashing European firmware and finding GPS, FM Radio etc don't work, can't make phone calls and texts.

Unfortunately that's not something I'm comfortable doing. Flashing kernels and ROMs I have done but never a modem. Maybe I just better stay with what I have and do without the multi-window function that comes with that ROM.
Same as flashing roms/kernels, single file, phone section of Odin. Most modem packages on here are CWM flashable which means you need root, though if you dig around you might be able to find Odin flashable modems. You can also download stock roms for your carrier & extract the modem.bin files from those & flash with Odin (rationale being you'd expect modems bundled with stock roms released by your carrier to give you good connectivity on their network in most locations most of the time).
Besides, this assumes you have connectivity issues with the modem that's bundled with the European rom you flash. It might work just fine. You're only going to know if you flash the rom & test/find out.
I currently have the stock rom for Australia XWLSH (unbranded) on my phone. It's rooted using PhilZ kernel. I've very happy with it as it is but would like the multi-window function while still staying with a totally stock ROM. The only way to do that is to use a stock deodexed ROM and the only one of those around here is the XXLSJ which is a european stock S2 ROM.
I can easily extract the modem.bin file from my backup image I got from sammobile but I was hoping I might be able to just flash the XXLSJ deodexed ROM and all would be fine (It is prerooted with PhilZ kernel).
from the little I have read about modem flashing so far suggests i might have to also flash a matching ril which further complicates things.
My USB port works fine, connects to my PC fine, i just prefer flashing to using Odin from my PC.
I wouldn't do anything with RIL's except as a last resort; I.E your connectivity is ****e/non-existent & you've tried the several dozen different modems that are available to no effect. Forget about RIL's until/unless you get to this point (highly unlikely).
If you're planning to run the European stock rom rooted, forget about flashing modems with Odin, every modem that's ever been released is available in a CWM flashable. Quicker/easier than Odin flashing them if you have to try a bunch because your connectivity is borked.
But...And I've already said this, you might find your connectivity is just fine as is after you flash that other stock rom. So try it & see.

Hello everyone, first of all I should post this to Android Development section but since system tells me I do not have 10 posts, I thought I can post this here.
Well basically I was using Disaster ROM for my SGS2 (International) (I'm in Turkey), and I wanted to use Biftor Rom which was actually KitKat and I didn't know that I should install CM 10.2 or newer first to install other KitKat Roms. So I actually softbricked my phone I was only able to go into download mode. So I flashed my phone with stock 4.0.3 using Odin. But I realised that my mobile network was actually slow as hell. Sometime it can't even connect. But I was like "Oh anyways, it will go away if I flash custom rom". But it didn't. I checked my IMEI and it was there, valid. I flashed my phone 4 or 5 times more with different ROMs. But no luck.
Then I heard an app called GetRIL, because someone told me that my baseband/modem thing might be corrupted. When I opened the app I saw that it says "Unknown RIL". So what should I do? I tried setting APN manually, then automatically by my Vodafone Service. Nothing happened, still same. I do NOT want to send this phone to Samsung Service, what should I do about this situation?
Some Details : My WiFi works very well, I can call other phones, I can send messages, I can recieve calls and messages, Only thing is Mobile Data So Slow and sometimes when I turned data on it says no signal for a while. Help Please !
EDIT: Stock 4.0.3 was only PDA file. It wasn't like 3-4 files to set into Phone section, Pit section... It was only PDA. At the moment I am using BeantStalk Rom 4.4.2 KitKat XXLPS Baseband.
Thanks in advance.

If you'd posted this in a development thread, you likely would have copped a slap (and quite rightly). Dev threads are for development stuff, not for n00bs having
problems with connectivity.
It may not even be a phone side issue, it could easily be carrier-side. Having said that, you need to try different modems. Plenty of CWM flashable modem packages on XDA you can try. Start with the modems bundled with stock roms released by your carrier (you can check these at Samfirmware, if you click to download a stock rom, it will tell you the baseband, you can then find CWM versions of these modems on XDA), test, if no better--->>> then try modems bundled with stock roms released by other carriers in your country, test, if no better--->>>then try other modems bundled with stock roms released by other carrier in other countries.
Thanks for the suggestion, today something strange happened and the signal "thing" started working somehow and i can use mobile network, but after phone calls it just disconnects for a while then reconnects again. It doesn't look so annoying so I will deal with it for a while. If it gets so annoying or goes into some crashes and other stuff I can apply what you have suggested.
I read some articles that saying XXLPS Basebands are actually not that well, If I try any other modem/baseband "thing", will it brick or something ? Or can i use 4.1.2 or 4.2.2 modem on KitKat ?
