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

Yes, all the versions I tried where UK modems.

Dont flash a kernel check the RIL thread but my guess would be network problem .

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,
Today I've installed the leaked version of Gingerbread on my Galaxy S but I'm having serious trouble with the modem. It barely ever gets a signal at all.
I've installed the KA7 modem and the signal is always stable.

^^;; The RemICS JB is currently being fixed. The current version is known to give no data or network as a result from a kernel issue...flashing any modems will not give you signal.....You really must read as much of the thread to the rom you plan to flash as you can before actually committing, otherwise things like this are bound to happen my friend ^^ If you did a nandroid I'd suggest reflashing that, or going to another JB or ICS rom until REM is updated.
Good luck!
Thanks to u all

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...
Sorry if my Thread have been suggested before i did not find one suggest over here
so my question is ... anyone did flash JB modem on ICS stock rom?
if yes and worked , can some one throw a link for JB modem for G.N SGH-I717 .. my single keep down almost the time :crying:
There is a search button and I've done it ..........
my addiction:Flashing.
thank you shy
i got lost in searching ... so please could you help me out !!?
Just type for modems .......im on mobile and working so i can't link you at the moment .... Try looking for ucmb4 modem for our i717
my addiction:Flashing.
I know what they say about assuming, so hopefully it only takes place on your part here, but if you're assuming newer = better, you're very wrong. If you're on ICS, you aren't going to net any improvement by going to a JB modem. I know, without a doubt, ICS modems on stock JB cause major problems, so they really are software dependent. On top of that, if you're going it hoping to increase data with another (not AT&T) provider, you're picking a horrible modem to try that with. UCMB4 is the crowned ICS king of reception & data, and the blaze modems are a close second.
Modems are independent of versions so flash any modem you want.

Never flash RIL on custom roms, you will break network.
Have you tried flashing an original samsung rom to see if network works? maybe your board is broken..

Are you sure you are installing the correct version? Have you tried reinstalling the custom rom(s)? I'm pretty sure that the custom roms use the same modems from the stock rom (doesn't install a new one). Is the network settings ok? Is there any signal strength? Please let us know your answers.

Emergency calls only? This seems really strange. Assuming that your sim is still activated, you shouldn't really be experiencing this problem. If you changed the modem to a different one from the original, I would highly advise you to flash back the original modem (since you have changed the modem).
That just dont makes sense, the only explanation to this would be a rom with a broken ril

Honestly I don't know. I never saw such a problem before, I don't know what you are doing wrong because all the kitkat roms for i9100 have a working network for a year I think. Make sure you are following the installation instructions correctly :good:

Well the stock rom you can get from sammobile and flash with odin, talking about kitkat I'm personally using the CyanogenMod 11 M12, network works flawlessly, but I also recommend @Markox89 linaro/sabermod builds because they rock (and have working network haha)
