hello fellow xdas
while back i had gotten my hands dirty with the CM10 project as i just couldn't wait for the official update! i learned quickly that i had serious problems with antenna/reception. i tried carious base bands (as recommended on forums) using GetRil/flash.Odin. this didnt seem to help, even though i would get better reception, my signal was unstable. In the process i tried other roms like JellyBam and had the same issue.
As this is my main phone and i do actually need to call with it, i went back to the stock rom i downloaded. but surprisingly i still have the same issue! GetRil also shows that i have incompatible RIL/baseband. this is what it shows:
RIL: I9100NELP2; I9100XXKI4
Baseband: I9100XXLPQ
FYI: i am located in the Netherlands and use T-mobile network.
so have i installed the wrong ROM or done something wrong in the process... ? does anyone have any experience with this? i much rather have CM10 but only if i can get to call normally once again?
thanks

Use either of the 2 links below to download either the NELP2 modem of the XXKI4 modem, and them flash them onto your phone via Recovery Mode. That should resolved your incompatible RIL issue.

thanks a lot zee54,
can i just go back to my CM10 or JellyBam, install the above mentioned radios and get everything working? or does it depend on the RIL which that ROM is running! I have tried a number of modems when i had CM10, but dont know if i tried those... i did try BVLP7 for sure
Based on this forum right here i need to have the I9100BOLPD ROM as stock for Netherlands T Mobile!

The modem is independent of the ROM, mate. So it wont make much of a difference whether you install the radio on stock firmware or on CM10. You could try using the modems mentioned by zee54 with CM10 and seeing if it helps. Also, give it about a day or so..since the phone tends to take a while to get 'used' to a new modem.

The unstable signal or "RIL Crash" as it it called isn't actually caused by having an incompatible RIL and Baseband (modem). It is a more complicated issue which I don't fully understand myself. But what I do know is that it currently affects all customs roms that are based on CM10 and use the CM Kernel. So switching modems might help recude the frequency of the problem but probably won't irradicate it completely.
You should not experiencing this problem if you go back to stock samsung firmware. If you experience problems you might want to do a full wipe (Data, Cache, Dalvic-cache) before reflashing and fix permissions afterwards.
On a more positive note, I have found that using the Siyah Kernel with your custom rom does seem to eliminate this problem, or at least reduce it occurance to such that I have not noticed it happening.
So personally i would suggest that if you wish to go back to CM10 or JellyBam ROMs, then do so but also install the latest Siyah Kernel for the S2 from here http://www.gokhanmoral.com/
(Here's the XDA Thread for the Siyah Kernel - [KERNEL] SiyahKernel v4.1.5 (v5.0a2))
I am currently running CM10 with the Siyah Kernel v5.0b2 and it is working very nicely
great stuff guys... 2x thanks for both of you!
Zeey54, i just had Siyah v5 Kernal installed, installing the latest JellyBam right now! so lets see what happens. i was suspecting that beside the RIL/baseband there were other factors as i did not see any significant difference between them. but then again i dont trust my judgement on such issues as my knowledge is quite limited.
will send an update with the result after installation in a few min.

installed the BOLP7 modem, overall reception is much better! data connectivity is also better and faster. but i still have some periods which my receptions drops and goes back up, seems like radio/modem crash (if im right). dont know if that is due to the kernel or modem or ...?
the reason i went for BOLP7 modem was because the latest official stock rom from t-mobile Netherlands was I9100BOLPM_I9100TNLLP8_I9100BOLP7, so i thought that would be the best one to try!
will wait a little more to see if this improves as the modem settles.
4th official ROM too much coverage you please make a review ?
need modem
First of all, thank you mate for your hardwork and awesome utility.
I have a Samsung galaxy S2 I9100G , recently flashed jelly bam custom rom. I am based in Saudi Arabia, the reception is not clear and people complain that it is switched off or out of network. I tried calling with another mobile and i got a response that my mobile is switched off, at the same time i checked my S2 mobile , it shows the full signal of the network in status bar.
what should i do? Which modem should i flash. the getRIL shows RIL/baseband is matching (I9100GDDLP5).
cheers

Hello all,
My Galaxy S2 (international version) is having wifi issues after I installed the stable release of cyanogenmod 9, and after flashing my modem. I'm not sure exactly which of the two caused the problem, if either, as they both happened pretty close in time. I was also under the impression that the modem firmware didn't affect wifi.
What normally happens is that the wifi will work for a few minutes and then stop. Also, despite not downloading any data, it says it's connected and has an excellent signal.
Any thoughts on what might be causing the issue?

Probably it is incompatibilty with the CM9. CM9 stock modem is good enough IMO.

I just tried reinstalling CM9 and I'm still left with the modem I flashed. So apparently CM9 doesn't come with its own stock modem. Also, the problem didn't go away. Might there be a compatibility issue between modem and CSC?

Hi all,
I installed PA v2.5. Everything worked well except my phone network signal. It is not detecting any signal. Did every thing i could do. wiped system/factory reset, wiped cache partition and dalvik cache. Fixed permissions. Formatted system. tried installing rom a number of times. Changed kernels from stock kernel to siyah 4.1.3 and 5.0. But none of the method worked. Please suggest the way i can get my phone signals as without network signal, it doesn't remain a phone.
Have you tried flashing another modem? You can download a modem here.
Why don't you try to install an other kernel? Different from siyah and stock... As kernels define how hardware work...

You installed siyah 4.1.3 with PA 2.5? They're not compatible and the phone shouldn't even have booted.
Anyways, if you're not able to get a signal, your modem has probably changed. You can check if the modem currently on your phone (settings>about phone) is the same as the one you originally had. ( I assume you've noted down your original modem details somewhere. And flash that modem from the link mentioned above. It should work

I had installed i9100DDLPA base version originally. and now i have flashed it. still not getting signal. sometimes it appears but disappear next moment. it happens frequently. Now i have switched to stock ics 4.0.3. but i want this rom. i flashed resurrection remix and found same problem. but flashing stock modem fixed it. But its not working with pa.
Use siyah 5.0 or dorimanx 7.4 (or higher if there's a later release.) I think the siyah dev gokhanmoral has blocked siyah 5.0 downloads for some reason, so use dorimanx 7.x for now.
Flash the PA ROM, it'll automatically install the default kernel its using. You can install dorimanx after that. And then if necessary, the modem that works for you. Also you can use the getRIL app to match your radio and baseband. May help.

Hi, i love PA too but we have the same issue. Not exactly the same though. I get signal when i boot my phone, i get an H signal (the highest i could get before the issue) but after flashing PA, it drops to E only after about 2minutes. Pls pls reply back if you found a solution. I have tried different modems and kernels already, verified that Siyah 5 is not compatible, tried DorimanX, same thing. Tried 2 different version of PA, no luck. Not to mention that i also tried another sim.
GetRil did it..
Hurraaayyy....
getRil app solved the problem.:laugh: It gave me the option of flashing modems which were matching my phones modem hardware. Thanks to all guys who helped me. Thanks a lot. Anyone having the same problem as of mine or any network related problem please give a try to getRIL app. May be it could work for you too.

hey, i got the sgs2 (i9100) and a stable cm9 for a while now. but i have problems with my 3g connection. i believe it is not my carrier, because i got two simcards (germany and austria) and the problems are the same: i got a (almost) full cyan connection bar with "H" or "3G" in my statusbar. but there is no connection (browser, yt, fb, etc...). only if i turn on flightmode, wait for a while and then turn it off again, then i have 3g for a while. but eventually it will break off again.
so i thought maybe it will help when i change the modem version. but for that i have a few questions:
- is "baseband" in settings/about the modem version?
- do i flash modems also via the recovery as i do with the rom?
- does the modem-sw come with the rom?
- where do i find modems and how do i know which are good (for me)
and while i am on it:

- does the kernel come with the rom?

yes baseband means modem.
You can flash modems through odin or recovery depending on which version you have downloaded.
Yes, the developer adds a modem to his firmware usually it is the best one for his region of the country as he is testing his software.
Look around of the thread posted about and check for your country code to find the best for you.
Yes, you can flash through odin or recovery.
yes, kernal comes with rom.
Some people prefe rcertain developers kernals, so they chane from stock kernal, also kernals for 4.0.4 and above have a brick bug issue in stock. Custom kernals have disabled this bug.
cm 9 safe because it is an older version. most popular kernals are siyah or dorimanx and some otherts.
Current leaked jb version need philz that is the only kernal beside stock that will work for the firmware.

what it doent say: is the modem included in a nandroid backup? will it be restored when i do a restore?

yes, if make an nandroid back-up modem is included and will be restored. If it is an older nandroid back up. it will have the version of the modem that was in use at the time of the back up.

No it won't, modems don't backup with a nandroid.

Haha, it's ok, pretty much everything get backed up with a nandroid but the modem (baseband) doesn't. Some roms install a different modem for you, others don't. Have a look at this thread, they have a list of flashable zips (cwm) of different modems and explanations. U might also want to read about the RIL and try the app GetRil, but apparently it can cause issues.. I don't fully understand it myself yet

Hey guys,
I've been running various JB ROMS for a while, mainly Omega but now on Fox Hound. Ever since I went to a JB ROM my signal strength when using auto or WCDMA only network mode has been really bad. I only get good signal when using GSM only. Problem is data is pretty slow on GSM.
It seems that JB modems could be the problem so I've tried flashing various other JB modems and even some ICS versions, all have had very little effect.
Has anyone else experienced this problem with low signal, I'm tempted to flash back to an ICS rom

Thanks JJ, I'll check the thread out. I'm not sure it's a network issue though as it seemed to work fine when I was on an ICS ROM.
Just tried a few files from the thread but still not very good. Think I'll try an ICS ROM.
Hi guys,
This is my first time posting a thread in here. I need your help.
My phone is Samsung Galaxy S2 i9100.
Baseband version: I9100XXKI3
(screenshots attached for more info)
I rooted my phone By using Odin3-v1.85. and flashed the recovery to cwm 5.x (i can't remember version) and tried to install custom ROM OMNI
(omni-5.0.2).
I accidently downloaded and installed OMNI for i9100G version. But my phone is i1900 version.
(I downloaded this omni-5.0.2-20141222-i9100g-HOMEMADE.zip ). i forgot to backup previous ROM .
Then i was unable to Turn ON my phone because every time i turn it on, it come back to recovery it self (it's a bootloop i think).:crying::crying:
then i flashed the recovery to CWM-KitKatCompatible-i9100 (version 6.0.2.7) and installed custom ROMs and tried (PACMAN,CM,AICP).
It works fine. everything is just perfect. But i can't make calls or receive.
It says "Mobile Network not available". when i call my phone from another phone i hear ringing it. But nothing shows in my phone. after few seconds i got a Missed call Alert. But this happens only sometimes. All the other times. i cannot call it from another phone.
I tried reset and flash modem using CWM as well as from odin. but no luck.
Please Friends Help me. I don't know whether i put this thread to right section or not. sorry about that.
I did all of these things by surfing XDA forum (as a Guest). And i'm happy about what you guys are doing. Keep it up.:good::good:

You will have to flash stock 4.1.2 rom or try a 4.1.2 custom rom. The problem may be caused by the drivers in the built in kernels but I'm not completely sure.
No mobile network on custom roms
I have already flashed the 4.1.2 jellybean rom but 4.1.2 rom also havr bugs. Lock screen doesn't work, I had tried hard resetting but it doesn't solve the problem.

Yep.
I am having same problem with the network connectivity. It happens with all custom ROMs that aren't stock based. I am stuck with Chameleon ROM which is a hybrid and has a stock samsung base. It is a great ROM but is outdated. I would like to upgrade. Any solution to this problem is welcomed. = D
Okay I think I got a solution here. The procedure is:
1) Make sure you are on a stock based ROM or other ROM where your network is working.
2) Backup EFS.
3) Flash custom ROM of your choice.
4) Restore EFS if there is no network.
Done.
To restore efs, you can use any app tailored to do so but for me it didn't work. I followed this thread:
http://forum.xda-developers.com/galaxy-s2/general/guide-recover-imei-9-steps-t1264021
Follow the steps carefully and you will have network in any ROM you like. Hit thanks if helped.
PS: Sorry for double post
EDIT 2: Even though my network is back, which confirms that the problem was with the missing IMEI. I found out that the IMEI I got now is a fake one. Got to get the real one back now..
i did flash android 10 in my moto one power
after that i went back to stock rom but noe netwrok is not showing up
