Hi,
I have looked all over this forum. I found the thread for the variety of modems/radios. I have a Galaxy S2 SGH i777. I rooted it and installed debloated UCMD8. It had ICS 4.0.4. The wifi signal reception is fine on both ROMS, but the cellphone reception IS TERRIBLE!!!
Does anyone have an opinion about this?
Thanks
Many people have reported good results with the UCMD8 modem, even in other firmware. However, different modems work well in different areas. You just have to experiment with all the modems to see which one works best for you. You can actually install any modem in that post with your current firmware, but you need to be rooted and have a custom kernel containing ClockworkMod Recovery.
If you're not rooted, you can use framaroot to root, and then use Mobile Odin Lite or Mobile Odin Pro to install the AJK kernel that is made for 4.1.2 stock. After that you can flash modems in recovery quite easily. I have all the modem zips on my sdcard so that if I want to change at any time, I can.
There r two ucmd8 modems available on xda one by creepyncrawly 4.70 mb and one by mr cook 4.75 mb. Any difference in both.
Secondly my wifi worked too good with ucmd8 but cell reception poor and with ucle5 wifi poor and cell reception good. Any idea

My first rom i flashed was stock deodexed 2.3.5 KI3. I found the BOKG1 modem worked best for me even at work with poor reception i managed to get H. Now i am using KI8 and it seems my signal isn't so good any more...could the modems work differently on different roms? I thought they communicated more with the hardware so didn't think the software would have any effect?
You can mix and match modems and roms, some modems will be worse in your area/network.

Have you still got the Rom you previously flashed?
If so extract the modem.bin from the Rom and flash it to your device using Odin.
There is a modem thread but not sure if the modem you want is available for download.

I had better data connection and so on with KI4 modem on GingerMOD 0.5 (KI4 firmware, android 2.3.4)
But with GingerMod 0.6 (KI3 firmware, android 2.3.5), KI3 modem is working better.
I've read here that a person is not locked into matching a Modem version to the Kernel version used and there may benefits in stability and battery life by using a different modem. That being said, Can a person use a GB 2.3.6 modem in a ICS XXLPH build?
The reason I'm asking is using a XXWLA4 Kernel with matching Modem and Multi CSC works for sending and receiving MMS through SMS when MMS fails on any and all ICS builds I've tried. Got to be something different in the Modem or CSC maybe?
There are a few things you should understand before flashing anything experimental.
Kernels are Android version dependent. Some can run on multiple version of GB, but you should check the release notes on a case by case basis. A GB kernel WILL NOT RUN properly on ANY ICS build, so do not go experimenting with kernels.
MODEMs on the other hand are software independent and you can run any modem with any Android version and experiment to find the best version for yourself.
I was aware about the kernels being android version dependent in order to be compatible and cannot be mixed. I did read about being able to mix or match modems without problem within different roms. What I could not find is any thing confirming that one could or could not use a GB modem within ICS.
I've been having trouble sending or receiving MMS in any Rom build I've tried other than stock kernels from sammobile. I figure its got to be something different either in the modem or CSC. I've been using only the MultiCSC packages when available as separate files. I wondered if trying a different modem, from a version that I know that works would help determine the cause being the CSC or the Modem.
Ive been using my i9100t modem from gb on ics lph thats the only way i get good reception.so yes u can.

Thank you very much. That is exactly what I was looking for, confirmation from someone who has done it.
Hi,
Im kinda new in the android section and need some help.
I have done CWM and Root via ODIN.
Now I want to install a custom rom. Rom that I want to install says XXALF6.
I checked my baseband and it says XXLE8 and Build : i9300XXALE8
So what do I have to do?
Just proceed and install it or do I have to do something else before I go on with it.
Many thanks.
You can just install the rom the baseband and firmware share version numbers I believe.

Thanks for your answer i just installed a custom rom. It works perfect.
My other question is now my baseband, firmware version changed does this affect my mobile data or any ways of my 3G connection like phonecalls, messages etc?
Baseband is not firmware its the Modem .
Different modems can be flashed from the modem thread .
jje
Thx for the answer, so I didnt flashed the modem? It's only the rom?
Yep,most of the custom roms do not contain another modem,you have to flash it via odin individually,or via cwm,if it is downloaded as a cwm flashable zip

Modems are unrelated to the Rom itself, so you can flash any you like.
The modems have vast differences in terms of network stabiliy and data throughput.
Many people, including me, have the best performance on asian big-city-modems (with S1,S2,S3) but in the end you'll have to try for yourself.
On S3 I've so far had the best experience with ZNLF2.
However you'll have to note that better signal/data throughput always means worse 3g battery life since it needs more power for the transmission.

Thanks, I understand it now
Like the topic says, I have an AT&T note, but T Mobile service. I recently (last night) found the wonderful work by several XDA members of which they supply us with a flashable zip that contains a radio that will give T Mo 4G data speeds.
I forget which one I finally used (there's the SGH-T989 KID radio, VKL1 radio and one called blaze). There is also a build.prop file that completely rendered my device useless (requiring an OS re-install).
I also have a few ICS modems, again the "KID" or is it "K1D" Im not sure... that, the "Blaze" version and one from the carrier "Telus". I also saw a Rodgers version floating around somewhere. I think that was really for the Galaxy S2 but it works with our Note
Anyway I am really missing ICS, I have 2.3.6 now. I need to know what is a good modem radio to flash if Im going ICS. Also whats a good ICS rom (keeping in mind the flashing of the T Mo radio)...
thanks
Roms and modems are interchangeable, meaning you can use whichever modem you want, on whichever Rom you want.
The blaze modem is what you want to use for t-mobile
Also the apn settings for t-mobile would probably be beneficial

So it doesn't matter if the Rom is gingerbread based but the modem is from an ICS build? And Vise/Versa...?
Nope
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
