This thread should be made a sticky in the Original Development forum. As modems, along with their proper RIL's is an important part in phones overall performance etc.
[Galaxy S II General] marcusjt:
That sounds like a reasonable assumption, but is it cargo cultism or has it actually been proven?

I would like to read more about any methodical testing / performance profiling that has been performed...
[Galaxy S II General] Jibreil:
It has been reported numerous times in many threads of folks loosing network connectivity at regular intervals due to improper RIL's files - as well as battery life improvement after testing multiple modems (personal experience included).

Hello guys, since i flashed NELP4+RIL i have a problem related to wifi. I use an application called Profile Scheduler (https://play.google.com/store/apps/details?id=com.wetpalm.ProfileScheduler&hl=it). This application can (for example) activate the wifi at a certain hour ( obviously determined by the user). This feature has always worked well until the day i flashed NELP4+RIL. Now when it comes the hour for the wifi activation the phone it's unable to connect to the wifi network, or well: the wifi is

enabled

but the phone it's unable to connect to the wifi network. If i shut off the wifi and then i reactive it the phone connects to the network

instantly

.

i've checked system->wifi->advanced->Keep Wifi on during sleep and the selected option is "Always", so this is not the cause of the problem. It seems a modem related problem.

I'm unable to restore the previous RIL files because before i had installed NELP4+RIL , i installed XXLPX+RIL so i lost the previous RIL files.

You guys have any solution to this problem? i'm becoming mad

DETAILS:

i'm on CM 10 + Siyah 4.1.5
[Galaxy S II General] CamoGeko:
Well I can tell you straight that the modem+ril files aren't related to your wifi not working properly.

It's either that app, the rom or a kernel that you're using.

[Galaxy S II General] snalfio:
i think that the application is not the problem, because his only job is to activate the wifi and indeed the wifi is active but the phone seems unable to connect to the wifi network..:confused::confused::confused::crying::crying::crying: so ok...it's a rom or a kernel issue... so the only thing i can do is to change rom and kernel?
[Galaxy S II General] rzat:
Start with wiping cache and dalvik and fixing permissions. It still no luck try different kernel
[Galaxy S II General] ApriliaM3:
As mentioned above, try clearing cache's etc. but also reboot the WiFi router.

Also you could try flashing another modem / RIL combo like NELP2 to put your mind at ease.

Hi all, I've found a strange thing: when I've flashed the Samsung XWLPF (stock without modem change) I've started to have a signal loss with the siyah kernel, then I've tried to use getril app to check if the modem and the RIL was aligned and SURPRISE! it isn't, the signal loss bug remain after the work of the getril app:( but when I've found this thread I've tried to flash the XXLPX modem+ril (this should be the stock modem of my firmware) and after that flash I've used getril again (I'm expecting the same mismatch as when I've started with the stock firmware) and strange :confused: getril reported the modem and ril match! Can someone clarify to me this strange thing?

Thanks in advance

Mario

P.S. Now I've switched to dream kernel to see if this signal loss bug still exist. So far so good :D

Standard modem zips don't install ril files. Getril is not always up to date and doesn't install all ril files either. The zips in this thread install correct modem and ril files though. That's why you experienced your issue with the original lpx modem and then with getril. After flashing lpx modem from this thread though, you are good to go.
[Galaxy S II General] CamoGeko:
It's also good to mention that not everyone needs to install these ril files.

Only those who are having issues with network connectivity or other anomalies should mess about with ril.

[Galaxy S II General] Mario1968:
Thank you, but what about the stock modem of XWLPF Stock (should be the XXLPX), when I'm first flash that firmware getril reported a mismatch from modem and ril, now after the flash of the zip in this thread the mismatch never exist. I hope you understand me because English is not my primary language.

A question guys.

Can I flash a 4.0.3 Modem+RIL on a 4.0.4 Rom? Any problems?

Thanks.
[Galaxy S II General] ApriliaM3:
Who knows why you experienced that mismatch in the first place... It could be from several different problems or a combination of them.

The important factor now is, you have a matching Modem / RIL combination and GetRIL is confirming it. Enjoy! :)
[Galaxy S II General] ballmead:
Works great for me using a 4.0.3 modemRil on both 4.0.4 and 4.1.1 Roms.

I'm restricted to I9100T modems and they haven't released a 4.0.4 firmware for it yet.

[Galaxy S II General] ApriliaM3:
It should work fine... I just wouldn't go as far back as GB but 4.0.3 shouldn't cause any problems.

[Galaxy S II General] a violinist:
Sorry for my stupid question, I read in the thread for a while but I didn`t find out.

Maybe someone can explain step by step:

How to install RIL_Restore from first page? Is it cwm flashable zip or should I unzip it and put the files somewhere?

And how to backup / restore RIL with it? In which folder will the backups be stored?

Thanks for help!
[Galaxy S II General] It_ler:
Yes, it's a CWM-flashable zip file.

Same as the ModemRIL zip file.

The ModemRIL zip file creates a backup of the original modem and RIL files, and the RIL_Restore zip file will restore the modem and RIL files from this backup.
[Galaxy S II General] tom_car:
Hey Everyone,

I've created one for DXLP9 and one for DXLP7.
[Galaxy S II General] danmullen:
When you flash a new ROM that contains libril.so (and probably the other RIL-related files too), I assume you need to reflash the modem/RIL combo. Could there be any negative effects of overwriting a newer libril.so? Sorry if it's a stupid question, I don't know enough about the RIL stuff yet :)
[Galaxy S II General] citytrader:
No, its totally harmless, a good thing to do is, before you flash a fimware, modify the RIL and Modem in the .zip of the new ROM and you wont need to flash the RIL MODEM combo.
[Galaxy S II General] ApriliaM3:
Dev-Host mirror updated, thanks.
[Galaxy S II General] kokesh:
I've got really crappy reception, signal drops and phonecalls get disconnected. I am on CM10 nightlies. What RIL would be the most stable for CM10? It is getting quite hopeless, with some RIL scripts I've tried I get no signal at all.
[Galaxy S II General] ApriliaM3:
I'm not sure you're going to experience any difference by flashing any of the combo's here but it's up to you to try.

In fact, if you substitute the word Modem for the word RIL in all of your questions you would probably be closer to the mark.

The RIL is unlikely to make anything more "stable" whether that be your phone or your signal.

If you're getting no signal at all, then matching the RIL to the Modem is unlikely to make a difference, measurable or otherwise.

Also, generally these combo's were created for Samsung based ROM's so I'm a little vague as to how they will perform when run on CM10
[Galaxy S II General] chillpcs:
I had a similar problem and found it was the sim card had become warn and loose. Taped the sim card in with some magic tape and it seems to be fine for now, just waiting for a replacement sim to come through.

Just a quick tip for ALL Indian users:

As this question has been asked many times on this thread and others. I've tried and tested almost every UK/European/Asia modem out there - and XXLPX seems to be the best for battery + switching between 2G/3G/WiFi + Net speeds.

After others signal drop, I've switched again to siyah kernel, then I made this test: I've extracted the modem.bin and the RIL files from the Samsung original stock XWLPF (downloaded by checkfus), then make it the flashable zip (using as template the XXLPX file from this thread) swapping the files into the zip, then flashed in my phone, now if I use getril, it shows mismatch (see the screen shot) baseband and ril, then the XXLPX files in this thread don't match the original files from Samsung XWLPF firmware.

Change your ROM, calling quality is not only related to modem, there are other factors, wipe data/cache and system and install a new ROM, I suggest you to install Neatrom LPY and try again.

For you notice: with GetRIL 0.9.5 beta (found in my thread in the signature) I've added support for multiple RIL files. I'm currently supplementing the entire RIL database for the Galaxy S II, so that all RILs contains multiple files, as reported here. I would like some help to test the beta version out before publishing the update on Google Play Store. Currently, not all of the listed RILs got multiple files, but at least 20 of them got it.

Hawkerpaul, I think we need to add another file, the RIL DAEMON rild located at /system/bin, I made a check and are all different between versions

Here is a graph that could be interesting to know.

Hawkerpaul, could be possible to modify the script to include rild and libril.so ?

If someone wants to colaborate in building a bigger modem+complete RIL database, please follow this steps (remember to include rild located at /system/bin and libril.so)

http://xdaforums.com/showthread.php?p=31312434#post31312434
[Galaxy S II General] hawkerpaul:
Thanks for that mate.

I looked into libril.so previously and was considering this. I think this may have something to do with Emergency Calls.

I'm not sure though if /system/bin/rild differs because its specific to the modem itself, of because its just been updated in the firmware itself. Just worried if this may have an affect on calls across differing firmwares.

Definitely worth looking into. Cheers again mate.
[Galaxy S II General] citytrader:
The rild should not be copied as Hawkerpaul demostrated it.
[Galaxy S II General] hawkerpaul:
Deamons in Unix/Linux basically are background programs that are constantly running and handle various requests.

the rild daemon will be what handles the call requests etc between modem and RIL.

I'll look further into whether or nor to include them in the CWM template. If so, I'll update all the CWM files I've done, any of which could then be used by yourself to recreate your UHLPH and XXLPS that you have kindly provided. Either way, I'll let you know mate.
[Galaxy S II General] citytrader:
Probably the daemon has to be according to the library, otherwise I dont find an explanation why they are different...
[Galaxy S II General] hawkerpaul:
Quite possibly, but its hard to say for definite.

The daemon may be updated due to the updates in the firmware.

It will be a tough one to call. I suppose the only way of finding out is to interchange the daemon between different firmware bases and test...
[Galaxy S II General] citytrader:
Do you know if there is a way to know the version of the daemon?
[Galaxy S II General] fr3quency:

I'm using this XXLPH baseband and getRIL says I should use XWLPO baseband, but I get a nice reception with this one and thought of two things:

-If there's a RIL for this baseband (couldn't find :(

-Or if the UHLPH is any different from XXLPH.

I'm using CM10 atm and also don't know if these modem+ril I find in this thread are compatible.

@citytrader:

Thanks for all your input and help in all this mate. You have been a great help to me. :good:

Remember everyone, like I said in my first post, feel free to use the CWM scripts as templates to make up your own modem/ril installers, as I cannot download every firmware that is requested as each is usually 400Mb+. I will continue to make modemRIL scripts for all the relevant ones I've downloaded in the past.

I'm still looking into if /system/bin/rild and /system/lib/libril.so should also be included in the scripts.

If testing with these files included seems ok I will update all the existing modemRIL files to add these files, and the new scripts can then be used as your templates.

I use T-Mobile in Germany and tested 4 different Modems/RILs from this thread: XXLPS, XXLPX, BVLP7 and BVLPE.

The 2 XX Modems didn't provide me H+ and P7 made my Phone to crash several times right after boot. Also P7 didn't provide H+ too...

At the end I tried BVLPE and that one works great for me (including H+), so thank you very much for this great thread! :thumbup:
[Galaxy S II General] hawkerpaul:
For your information, I'm now ruling out putting the following files into these scripts:

/system/lib/libril.so

/system/bin/rild

I tried bundling the BVLPE versions of these in with the script and flashed onto my Neat LPI and it lost my IMEI number and gave me no service whatsoever. So I've restored back the relevant files off the Neat zip and put my BVLP7 modem/ril files back on.

I will look into uploading some more modemRIL flashable zips as soon as I can.

[Galaxy S II General] hawkerpaul:
Which official firmware was this modem released in?

I'll have a look into it.

I assume this is a modem from a GB ROM, so If I do manage to get one done, I've no idea what would happen if this was flashed onto ICS.

Hi guys,

I'm currently in Hong Kong running CM10 JB on my S2, what is the best modem to use? Another Hong Kong user is using ZSLQ according to my search on this thread, I flashed it, but my BBC, Engadget app would fail to load/refresh the first time I open the app. I would have to refresh it once or twice for the app to refresh its contents. Is that an indication of running a wrong modem? It hasn't happened before when I used the stock modem that came with CM10.

Any advice is appreciated.
