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.
Thanks

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.

This is my modem then.
Can I flash any modem, or it must be specific to my phone's model (S2 SHV E120L)?

I believe you have to flash a modem designed for your device specifically.
I suppose you will find it in your device forum.

I have a question for you guys. My mate and I were sitting next to eachother comparing my S2 and his Note last night. We have the same provider obviously. While I had 1 to 0 lines of 3g signal, he had 4 out of 4. I'm running XWLPG with stock modem. Do you think that by changing modems I could improve my signal to be at "Note" level, or the two phones carry simply different hardware and the S2 will never catch as much signal as the Note does?
Thanks,
td
Try other modem, they have great influence on signal. There is a thread about it on forums. KH3 modem is recommended by many users. Good luck !

Look in the modem Thread its different where you live and which provider you have. Test all modems and look which is best for you
Galaxy S2`s are generally incapable of accurately reporting the signal strength (as you will read if you do a bit more Googling) so I wouldnt worry too much about comparing the two different machines.

I know that I can't ask which modem is the best etc, but I have one question regarding which modems to flash. Are they somehow linked to a specific rom / kernel / android version? For example, are modems released in gb roms supposed to be flashed under ics roms?
Every modem can be flashed to your rom, thats no problem

Hello, I've flashed the Cyanogen mod for my Samsung Galaxy S2? I've been using it, it works fine.
I'm wondering, do I need to flash a radio? If so, which one? I've seen the links of radios from the Wiki page of Cyanogen under Support Downloads, just don't known which one to use or if I'm supposed to.
Thanks for your help.
Radio is not changed by CyanogenMod.
If you have no call, sms or data issues then i dont think you need to change

OK, thanks for your help.
I have successfully installed this rom. I think it's the most amazing jelly bean rom for galaxy s2 at the moment. I like its smoothing and quick response. feel a bit warm at the back and the battery is losing 1% at every minute while wifi is on. Over all is great. Cheers!
Actually, I've been experiencing data connection problems. My phone works, but it won't connect to 2g/3g for internet.
Should I try switching radios?
If so, which one is recommended? Or do you just try them at random?
Thanks again
On first boot normally can't get mobile data to work because APN was not configured properly (or the list empty), after a reboot mobile data will work again. If it doesn't, then you have to key in the APN manually.
For radio/modem, since there are no changelog released and nobody know what are the differences among them, it is assumed that the latest one will be better.

first and foremost asking or recomending which ROM/KERNEL/MODEM ,is against XDA rules, since all phones are different due to various reasons , hence if u have a an issue with ur modem u have to try a cpl of them on ur own and see the one suits u the best.
link for the same below.

OK. I'll try a few different radios. I see a list of links in the Cyanogen Wiki page of under Support Downloads.
Thanks for the quick replies!

It sounds like your apn settings are messed up. Try to reboot twice and then try. If that doesn't work, you will have to find the settings and input them manually.

Thanks everyone! The radio did it!
I flashed this radio:

Now, the data, 3G, works great.
I've been experiencing an issue and have read several post about RADIOS on the SGS2.
I flashed my mobile with the nightly 10.2 CM and after that it started to ask me for "SIM network UNLOCK" Which I can't unlocked, thought it was the version issue so I dl a the newest one and same issue, I tried the ICS stable 9.1 and same issue.
I've read something like radios on the CM support part. Which I dunno where is it yet . If I need to flash it and u guys can help me out to pick up the correct one I'll appreciate it. my model of SGS2 is the i777 from AT&T.
May I install NELP on my CM 9.1? how? where can I get the files to do it?

What phone do you have? This is the thread for the i777 S2 variant, and at least one of the modems you mentioned are for the i9100 variant (don't recognize the others you list).
You can only use modems designed for your device, so if you have an i777 see the link directly above your post.

Sorry, wrong thread. Hadn't time to ask for delete my post :\
On my i9100 I have a really strange signal problem my suspicion is a hardware issue.
Let's start with the actual problem, from the title you can tell its signal related, it constantly is really low but in some places full. In places where other people on android get full signal I get no signal what so ever. I have tried a custom ROM (super nexus JB 4.1.2), I've also tried a few modems giving each a few days to test but they all act the same so I don't really know what to do in software terms. Any ideas anyone?

If you already tried different modems (and RILs?!) it could be a carrier or hardware issue.

Yeah I used getRIL for the RILs and as I say there's no difference, also I've tried sims from different networks in my phone and doesn't make a difference but they work perfectly in other phones so it mist be a hardware issue

I'm still using Slim ICS with 4.0.4. The GPS is ok, it works but still not great. I don't think my phone will ever be great though. I want to try out SlimBean but it seems they are having GPS issues among other things.
Honestly, I've found that GPS can be a real hit or miss depending on your specific phone.
All hardware is not created equally, unfortunately. I'd suggest testing a few different roms and find which works best
for you specifically...because I've had luck with GPS on roms where users have reported bad GPS, and no GPS on roms where
awesome GPS was reported.
Good luck!

I would use either PA or CM10, but you need to flash the 3 gps fix files located somewhere in the PA thread. I would not use Slimbean 3.0 if you really need GPS since even if you do flash the files, no satellites come in view at all. I got a lock below 10 sec outside driving on monday at 7:30 pm. Accuracy was about ~25 feet, so it was really good. I was on CM10. Anyway, both have really good GPS as long as you have the 3 GPS files. They are called: GPS - Experia Files, YAGF2, and cwm-cm9-gps-wrap. Flash it in the order I wrote it in. They arent hard to find. Just type the names into Google. Or look in the PA thread. Good luck bro, and as Xenoism said, it also varies with device. If your device was made before Nov 2010, you probably wont get a lock no matter what unless you did the hardware fix. Even with the hardware fix, you'll still need these 3 files.
EDIT: Because I'm nice, I found the post where Jrafael posted the GPS files. It is here: http://forum.xda-developers.com/showpost.php?p=33575684&postcount=504
I have great gps with SlimBean and the 3gps fixes, its even better than my Galaxy Nexus. However, I owned a couple Vibrant and they all seem to have difference performance. Try the hardware gps fix if you're brave.
Note that for SlimBean if you patch mismatched patches it can make GPS stop working completely, only patch gapps from their own site.

Which version of Slimbean are you on? 2.9 works fine, but 3.0 is stone dead. (From my experience and a bunch of other members) I flashed the files and rebooted, tried getting a lock and not even one satellite appeared. Usually on other roms i get locks in less than 10 secs and after deep sleep, less than 20. I dont think he'll need the hardware fix if his phone is built after Nov 2010. But if its built before, then he'll definitely need it if he needs GPS that bad. That or get a new phone with GPS or buy a GPS :good:
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.
