[Q]question about modems/radio - Galaxy S II Q&A, Help & Troubleshooting

hi
i flashed the latest stock I9100XILA2 (Italy),just flashed the csc for my country instead of italy.
I saw that the modem shipped with this latest rom (januar 2012) , XWKI1 is older then the one that came with my rom xxkk2 from november 2011,which is xwki4.
is it recommended to stick with the modem that came with the rom?like are there optimizations in that rom for that specific modem,so it works best with that rom?
Or doesnt it matter what modem one uses?
i tested both (flashed with odin),but no way to judge on the performance,because of heavy fluctuations on the local net,which gives very different results after each test run,with both modems.
Apreciate any information on this.
Thanks.

Try out a bunch of modems and use whichever gives you the best performance. You might need to test each in different locations/different times of the day & so on to get a good guide. That's what I did before I settled on the modem I've been using for the last month and half.
No need to stick to a modem that was packaged with a particular rom

thanks for your answer
which modem do you use now,or do you think is the best for you?
cheers

[Q] GB XXWLA4 Modem in a ICS XXLPH rom

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.

Re-flash stock firmware

hello everyone.
I'm using andyx firmware v15 and taking my attention that battery dies too fast and phone feels lagging at times.
So i want to go back to the stock firmware and use a rooted stock firmware. but i have a couple of questions:
1) i dont really know which pda or country's firmware i have to use.bought my phone from poland and living in turkey now. can i find out which version the phone originally came with from the box or anywhere else?
if using any firmware wont matter, is there any particular one i should use? maybe getting the newest updates before the ones?
2) is the version 4.0.4 safe to use? my friend suggested me to use that one but i'm a little pissed off after reading the brick stories about it.
3) also someone else told me to flash stock firmware then go for the siyah kernel. whats the benefit for that?

1) there are no particular firmwares. Try out different firmwares on whatever suits you best. I suggest you go up for Gingerbread because of its stability and battery life. But if you want to be updated on the trending things, go for ICS.
2) i suggest you go for custom roms with 4.0.4 as a basis.
3) siyah kernel MAY be a suitable kernel for you, but then again, it could be different. Try out different kernels that best suits you

Use CheckFus to find the latest firmware for your phone and flash it with ODIN.
To root your phone just do some reading. There are quite a few methods described here, some are easy, some are more complicated. In the end choose one that corresponds to your needs and skills.
Ive just done what you were asking for similar reasons. I went on to samfirmware site and picked latest and safest ROM. Then on to chainfires thread for the insecure kernel to root my S2. (thanks to chainfire) No a difficult task just read before flasing and make necessary back ups. All tbe best.

[Q] Modems and Kernels

Hi Everyone! As a part of the usual process when I'm flashing a new phone, I start reading the forum to see what I can and cannot do. Believe it or not, this is the first android device that I own, every other phones weren't just mine. Now, I have two simple questions:
I've flashed some other phones, but in those I've never had to deal with modems or basebands (except from the nightmare called iPhone ), I wanted to know, the roms come with their own Basebands and Kernels or I have to flash'em separately when upgrading to a new rom, OR I can use deriberatly the modem that works best? I ask this because so far I haven't seen any indications on the ROM threads and I saw the compilation post of Modems
As of the kernel I'm not so worried, I'll simply use Siyah's kernel
Thanks!

Thanks for the answer, but I didn't explain myself. I saw that thread, actually I mentioned it above. I will have to test the various basebands, I live in Venezuela and there's no recommendation on the map for my country.
Now, resuming and explaining myself better, I just wanna know if Roms have their own Baseband and Kernels included (or just baseband for instance), and if there's any Baseband requirement on the roms -- Obviously there are Kernel requirements.
Thanks!

They come with their own kernel and you can flash over that. Fairly certain they don't have a modem but don't quote me on that. You have to get a Sammy modem for a Sammy ROM and a aosp modem for an aosp rom

For clarification, the only difference in the actual modem from aosp to Sammy is the install script. The modem itself is identical.

Just to clarify this. Some roms have Aroma installer which gives various options or features to flash with your rom on the initial install. Depending on what the developer includes, different kernel and modem choices are possible.

[Q] Reception / antenna problems (GetRIL)

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

[Q] can i flash JB modem on ICS stock rom ?

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.
