I am no Noob to Android, but am to Samsung phones. This is my first time ever encountering kernels and modems that could be flashed separately. All other Android devices I used had everything together as a single package and did not offer a kernel and modem separately.
That said, I am trying to determine a solution for a frustration of mine. I want the newest Gingerbread 2.3.6 version for my ATT Galaxy S2 (NOT Skyrocket), but every time I check for updates, my phone says that I am up to date already. Yet, there have been three newer firmware versions leaked and I dont know what this means, but I am wondering if ATT is leaving me in the dust or something.
I have tried all three of the leaked updates (UCKJ1, J2, and J4), and although the phone works perfectly fine, all versions give me an impossible to deal with problem when I am in a call with someone. The problem is that no matter who I am talking to, they all complain that they cannot hear me because my voice is randomly fading in and out to the point where they cannot hear me at all. Strangely though, when I am on UCKH7, everyone says that I come in nice and clear and no one ever complains about clarity.
So, I was wondering first, what controls the calling portion of the firmware/
ROM? I was thinking that it was the modem, but when I think of modems, I think of something controlling internet, like 3/4G and wifi.
Second, if it IS the modem that controls the calling, then what would happen if I flashed the UCKJ4 firmware and the UCKH7 modem? Will everything work?
I was thinking that since H7 seems to be the only version that doesnt give me voice problems, then by using its modem with the J4 kernel, I could have the newest firmware, but still have people hear me.
If anyone knowledgeable in this area could help me, that would be ridiculously awesome! I dont want to try this unless I am sure that I wont brick my phone or something.
BTW, the voice problem is not caused by finger over microphone or my or the other party's reception. I have tested this as thoroughly as possible and it is definitely the firmwares for some reason.
1) your modem controls both the calls and data connection.
2) you can flash the stock KH7 modem:
http://forum.xda-developers.com/showthread.php?t=1336958&highlight=UCKH7+modem
you can do this without changing your rom or kernel. Hope that fixes your call issues (sounds like it will).
Modem controls calls and data connection, however the Samsung Noise Reduction feature is in the audio libraries within /system and to some degree in the kernel (sound drivers)
Ok, so the modem does handle calls then. Thats good to know!
For the record though, the noise suppression feature seems to have no affect on this problem of mine. It doesn't matter whether it is on or not :-\
I am CURRENTLY running KH7 modem AND kernel and no problems right now.
Soooooo... What would happen if I flashed the J4 kernel, but the KH7 modem though?
Will things work right (data, wifi, phone calls, system stability, etc)? Will I lose noise suppression?
LOL, thanks for the replies so far, but my questions were only half-answered. (Probably too much text in my OP... sorry!)

Most likely not much - the only case where you're likely to notice a change is if you flash my kernel, which pulled in the I9100's latest sound driver a few days ago.
Please forgive me for not fully understanding all of this.... -_-'
So, it isn't worth it to flash the J4 kernel (in order to get Gingerbread 2.3.6) and the H7 modem (to keep my phone calls clear)?
If I flashed your kernel though, how would it affect my phone?
Will I be at 2.3.6?
Would I flash your kernel, but keep the H7 modem?
Also, can you provide a link to your kernel (to make sure I find the same thing you are talking about)?
Again, forgive me for not understanding right away.

Is anyone else having issues with the other party hearing you in call? I have a case, and no matter if I have it on or off, the other party can't hear me unless I talk louder than normal. I don't recall having to talk that loud on my iPhone to be heard. Was happening on CM7 and latest UnNamedROM.
I've encountered the same issue. I've been running unnamed since the day I got my phone, and am ocrrently on 2.2.1. I've read of others having this issue as well. I've also read somewhere that disabling the noise canceling feature supposedly helps. I've done so, but not sure if or how much it helps, as I can't hear myself from the other end. Perhaps someone else can chime in with advice regarding this topic.
So I was doing some more tests. It seems I might be holding the phone away from my face when I speak in an effort to not get face grease on the screen. Will have to do more testing to verify.

I too have this issue whenever I use the UCKK6 modem after the OTA update. Whenever I was on the UCKH7 firmware + modem, I had no problems and when I use the UCKK6 firmware + UCKH7 modem, I also don't have problems.
When using the UCKK6 modem though, I get a LOT of people complaining that they can't hear me and will sometimes even hang up on me because they think my call dropped (I'm still there though and can hear them perfectly).
It sounds like your mouth is being muffled or like you are underwater- or like you are randomly teleporting yourself across the room, while leaving your phone in one place.
I have done several tests myself by calling my house phone with my cell and putting the house phone on mute (to prevent echo). I then hold both phones to each ear and basically talk to myself. One test even involves me saying the alphabet. I have done these tests several times using both modems.
My tests gave me the conclusion that the K6 modem is buggy, but is especially unusable with the noise suppression turned on. When on, certain syllables seem to get cancelled out by the noise suppression, as though it thinks that part of it is background noise. However, even with the noise suppression off, I still get the occassional fading of my voice, but it is extremely occassional compared to when the noise suppression feature is on, where it is almost every couple words or so.
With the H7 modem, I notice no problems whatsoever, whether the noise suppression is on or off.
So, I recommend doing one of the following if you are experiencing these issues:
1) Revert completely back to UCKH7 firmware and modem if you want/need the noise suppression.
2) Use the UCKK6 firmware with the UCKH7 modem if you want/need the noise suppression.
3) Continue using UCKK6 firmware and modem, but turn the noise suppression off.
1 and 2 are sure fire ways to not have any issues at all. 3 may still give you problems, but it may happen once every few minutes with noise suppression off (still there, but not nearly as noticeable), while once every couple syllables with the feature on (very freaking noticeable!).

So I started having this issue a couple days ago.
I've tried going back to the KH7 modem and still not working. I even tried restoring to stock.
Mic works fine in speakerphone mode, but I get absolutely no sound otherwise (I can shout into the phone and the other side hears nothing). Noise suppression toggle doesn't do anything.
Thoughts?
I guess I'll try taking the phone into ATT this weekend.
^
That sounds like hardware issues, so yeah, bring it back to ATT.

The above code does not work on AT&T version, I guess. At least it did not work for me. Don't know if root makes any difference, yes I can have booster apps. But again people have reported that this does not seem to work.
I happen to read in International s2 forum that opening the phone and making a bigger hole for mic helps. Or even cutting a slice of the white protective casing around the lower micophone seems to help as well. I did not want to tamper with hardware at the moment, as I am just 10 days past my warranty period.
Let me know if someone knows some funky codes to get this fixed. I am running 2.3.4 stock ROM and not rooted yet.
- Thanks

I'm on AT&T and the code worked for me, however I'm still having the issue. I don't necessarily think messing with the hardware by cutting or slicing will fix it because (for me at least) the problem is intermittent. Sometimes I'll go afew days without the problem, then I can have 3 calls back to back where the person doesn't hear me at all. It can happen both when I initiate the call or answer and it doesn't always happen in the same point of the call. This is pretty frustrating, I really hope there's a fix because I don't want to have to convert to stock and deal with AT&T.
I had this issue. Mine was not intermittent, the mic just stopped working. No amount of flashing or resets from ATT could make it work again.
Strangely enough the speakerphone worked fine and that just screams software issue, but AT&T chose to replace my hardware.
The problem seems to be intermittent for me too.... I don't know how the code works for Griffon23, as AT&T has disabled that on our model. I have not updated to 2.3.6 as the firmware ushers in loads of problems.
I really hope there is a fix, I am just being lazy to flash new roms and stuff, as I might have to return this piece of S#$#t due the low volume and poor mic. Such a shame that expensive phone like this has issues with basic functionality, voice calls.
I also tried good in ear headphones, that solves the problem of low in call volume but not microphone, which simply points that there is some internal problem. May be hardware or may br firmware. And May be ICS update can fix this for us. Fingers crossed.
Thank you Samsung!

THIS. I was having a similar problem a while back. People were telling me that my voice was cutting in and out a lot. Not even looking for it, I found this thread and flashed the UCKH7 modem. I also read somewhere that it helps battery life too as that's what I was searching for.
Anyway, It's now been several weeks now and I had forgotten about the problem until I saw this thread again. I guess I'd have to say that the UCKH7 modem definitely solved my problems as I can't remember the last time someone complained about my voice cutting in and out.
Since this is the only thread similarly related to my issue, I'll continue this one instead of starting a new one. So I've tried the above listed suggestions and the dial code for the audio does not work for me, as a matter of fact, none of the dial codes work for my phone, I get a "Invalid MMI code or no connection" error. I Have not been able to make a call on speakerphone since I flashed my phone for the first time back when I first got it. I've switched around from different ROMs and I get the same issue. The main issue is that no one can hear me when I'm on speakerphone, but I can hear them. I can make regular calls just fine. I've even flashed back to stock and the issue still persists. Are there any suggestions? I am currently on the latest AOKP build of ICS.
If you've been flashing different ICS roms, there's a chance you flashed one of the mic-swapped kernels. Try the AOSP/AOKP version of NEAK. Make sure to wipe cache and dalvik before flashing.
EDIT: Didn't read your post closely enough, if regular calls work, the kernel shouldn't be the problem. Maybe the modem? UCKH7 is what most people report with good results, depending on area.
Have you ever been able to use the speakerphone? Do you know for certain that it works?

I just came across this thread after a long time. I was surprised to see how much it has grown!p and how many people haod similar issues as me!
Well, I kind of wanted to give an update and suggestion for those who still have issues.
First my update. Since having these issues in UCKK6 and ICS leaks, I actually gave up on ATT's firmware and moved on to custom ROMs. Currently- and loving it- I'm on a ROM called Mystic's Pride (will be going to Mystic's Glory, a more advanced version- once it is out of Beta testing). Mystic's ROMs are ported firmwares from the international SGS2, but they use the latest ATT modems since the international version's will not work on our phones.
Using a custom ROM will NOT fix the call quality issue. That is all linked to the modem.
Now the suggestions. While running UCKK6, I discovered that you could use the UCKH7 modem with it. So for a while (until I noticed excess battery drain issues), i was using the UCKK6 firmware with the UCKH7 modem.
NO MATTER WHAT VERSION FIRMWARE YOU ARE USING (Gingerbread OR ICS), YOU CAN USE THE UCKH7 MODEM!
As I stated in my update, I am running a custom ROM now, which is Android 4.0.4. Im still using the UCKH7 modem and my calls are super clear and I am not having any issues with people hearing me.
You may be asking, "If you are now on ICS, then why not just use the latest ATT ICS modem?" The answer is simply that after all of my experiences with horrible call quality using official ATT modems, I simply do not trust them anymore. I know of one modem that works, so I have stuck with it without issues. I plan to test out the newest ICS modem though... just to see how it compares with UCKH7. If no good, then its back to KH7.
So, if you are still having issues, then try flashing the UCKH7 modem to your phone. You do not need to be rooted in order to do this. All you need is Odin and to boot into Download mode.
If you flashed the KH7 modem and still having issues, then you most likely have a hardware problem.
Another thing I noticed while still using UCKK6 with its corresponding modem is that by turning off the Noise Suppression, you can get better quality calls. However, using UCKH7 modem may make your calls clearer, but will allow you to use Noise Suppression.
I hope this helps somewhat. I have NOT sent my phones in for repairs/replacement for this issue and my calls are just as clear as the day I bought my phone.
Ill try to pop in here to answer questions, etc if needed.

Lol spexwood, I know you're trying to be helpful, but I gotta let you know your post is way old news. It's been common knowledge for a long time that you can flash any ATT I777 modem with any firmware, using ClockworkMod Recovery. It is useful (to me at least, didn't know this before) to know you can also use Odin to flash modems if you don't have CWM, but most I777 users around here have it because they use custom kernels and ROMs. There's a whole thread which contains every single modem in CWM-flashable zips, and it also contains a Google map with notes about which modems users have reported working best for them in their respective locations; this might be helpful to you if you didn't know about it beforehand.
tl;dr - try all the different modems to see which one gives you the best speeds and call quality in your area, they are interchangeable. Use this thread to help you out.
This is one problem I've had when completely stock, ics, and jb. And it mostly occurs when I have ear phones plugged in

Hey all. So I've been running CM7 for a few months, and most recently also flashed the Kang ROM. However, also for the past few months, I can't remember if before or right after CM7, I've been having a very distorted call quality, as well as data connectivity disappearing, only coming back with a reboot. I was wondering if someone could direct me to the best modem/radio combo I should be using... I figured this is most likely the culprit, though I'm in the dark. I believe I'm currently using EC09... my baseband version under "About phone" is S:i500.04 V.EC09
Even if EC09 is the newest modem I could use, what else is compatible with CM7? I feel like the biggest noob ever, but could someone explain to me exactly what the modem and radio are specifically responsible for?
When I find a modem/radio I'd like to flash, can I just do that over what I have now, or do I have to flash an earlier build like Eclair or something and rebuild from there?
Flash the EH03 radio. You can download it from me I will post a link. Use Odin to flash it right over what you currently have. It will not mess with your ROM so no need to do anything else but flash this file

Sent from my SCH-I500 using XDA App
Thank you so I don't have to wipe a single thing before flashing? Should this remedy the call quality, loss of data connectivity, or both?
I didn't see much of a difference between those two radios on the CM7 kang, but it's worth a shot. MTD roms tend to have data issues from time to time, but if you lose connectivity, toggling airplane mode on and off usually worked for me, as opposed to fully rebooting. Call quality could be related to your signal strength and other factors on the other end of the call. Unless all calls are distorted?
Yes, all calls are equally distorted. Significantly worse than the phone originally was
No you don't have to touch a thing with your ROM. Odin that file and it will reboot to your rom with the new radio. I'm running eh03 on ics build 6 and it's great
Sent from my SCH-I500 using XDA App
the radio will not make a differenc on call audio quality...use glitch v13.1, the audio is much better than the kernel that comes with cm7.
Thanks for your help everyone. I'll install glitch as well as the new radio.
I asked before, but can someone please explain to me exactly what the modem and radio are responsible for and what advantage there is to updating them?
Also, i've never installed a modem or radio without installing current builds of both at the same time. Will it matter that upon installing the above radio, my radio will be more current than my modem?
Your radio and modern are actually the same thing. It can improve your signal/connection from Verizon so it it important to have a reliable radio. EH03 is a stock Verizon radio so we know it's reliable and the advantage is knowing you have a good reliable radio

Sorry if this has been asked, but I have not been able to find a solid answer yet. Can I install " [ROM]UCLC2 Official ICS "Leak" I777 (3-27-12)" on my S2 with the baseband version UCKK6 and be alright? I had an incident where I put a kernel that wiped my wifi capabilities a while back and wasn't sure if it was because it contained a different baseband. I'm not sure on which modems/basebands I should stay away from?

That would seem to be true, since the modem.bin "image" is really just a mini-kernel and real-time OS (ThreadX I believe) loaded by the modem and only talks to Android via the RIL abstraction layer.
But on the Captivate, when using an i9000 ROM (similar to the use of i9100 ROMs here) you actually had to use an i9000 modem too. In fact the rule generally was, the modem had to match the kernel, as we had separate kernels for i9000 and i897 ROMs. This of course opened up many more options since the international variants inevitably have many more modems available. Point is, on the Hummingbird platform, the modem/kernel (and usually ROM) were somehow interdependent on each other. Maybe due to quirks specific to the RIL in each? Or maybe something else? No idea, and not sure that anyone ever bothered to figure it out. (Why people aren't more intrigued about trying to "hack" the modem binary is beyond me. I don't care if my phone violates the law or gives me cancer as long as I get better reception and data speeds... )
Any ideas as to why this wasn't the case with the i777?
In particular on the Captivate, running a mismatched modem would result in voice calls not working properly, though data would usually work, which isn't all that dissimilar from what happens on the i777 with a mismatched modem/kernel/ROM combo.
Just looking for any solution that would let us run i9100 modems on the i777 in particular since there is no proper way to adjust the bands selected by the modem. Aka, that whole stupid RAT restricted bull**** business that AT&T seem to enforce on the UCXXX modems.
Thanks in advance!
And PS, I'm not kernel developer (though I am studied in C/C++), but if you pointed me in the right direction as to where I might be able to find some useful RIL debug output, I'd be willing to pour through some logs looking for anything interesting.

I think that in the case of the I9000 vs. I897, the modem/CPU audio interface may have been entirely controllable by software.
On I9100 vs. I777, there appears to be some hardware in between we don't have control over. As a result:
An I9100 modem on I777 results in no audio regardless of kernel.
An I9100 kernel on I777 results in no audio regardless of modem. I know this end of things - one of the digital I/O channels is set up very differently on I777. Master instead of slave I2S (or was it the other way around?), 16 kHz sample rate instead of 8, and a few other settings are different.
There might be something about that "in between" block we don't know about and can control with the right knowledge, but right now - there's an unknown black box somewhere and it prevents I9100 modem firmwares from providing call audio.
Hello everyone,
I'm not sure if I'm the only one or not since I haven't seen this issue in any of the threads for any JB Roms. This doesn't seem to be a problem for any 1 Rom, so I'm thinking it has to do with the CM10 base everyone is using. Here is the problem:
Everything is fine on the Rom for a few days - I can browse the web, make calls, get emails, etc... Then, I'll make a call, and the call will connect (call timer starts on screen), but I can't hear the person on the other end, and they can't hear me. I know this for a fact because I called my wife's phone which I was using as a test.
It would continue to stay like this (even after rebooting normal, rebooting to recovery and wiping cache / dalvik). The only thing that seemed to fix the problem would be to re-install the Rom.
For now I'm back on one of the CM9 Roms, and everything is ok. I really like CM10, but don't want to potentially get into an emergency situation, and then not be able to use my phone, or go to make a business call, and look like an idiot because people can't hear me, etc...
I just wanted to know if anyone else has experienced this, or has a fix? Thanks for your input.
what Rom ? (specific)
what carrier? ( is this an ATT device running with a different carrier? )
what region? (are you in the US, Canada, or elsewhere? )
Most reports are leaning toward the modem as the issue. If we know the above information, we can suggest a fix or patch based on them....g

The last modem I flashed directly (unless one was cooked into a rom), was UCLF6.

Lets test this a bit more....
Download and flash the Stock, UCLA1 modem, then reboot it 3 times. then try a call to a test device.
I've had marginal success with the modems above the UCLA range, and am using the UCLA1 Modem on virtually all of the roms I use. ( now if I could get all 1352 apn's from the stock rom to work...LOL ).....
It may show up as "unknown" in the "about phone" settings, but based on the tests I've done with it, you should be safe on the IMEI loss issue that some TMO users are reporting.
There is always that chance, but where you are US based on ATT, and that is their modem, you should be fine.
Test that bad boy out, and report back if ya would...thank you....g
I think its just the cm10 roms ..mainly because I've seen a post like this in all the JB forums...

My dad (who uses an iPhone) and a few other people have been complaining that whenever they call me, they get really bad static or sometimes even echoed feedback during phone conversations. I've tried multiple different ROMs and he says it still happens sometimes. What confuses me is that its kind of random when it happens because other times it'll work perfectly. The mic isn't broken or damaged because recording apps don't have this problem. Is it something in my settings and/or the ROM causing this? Any feedback is appreciated.
I'm currently using the latest shoshock ROM and have in the past been using tasks AOKP, which is where it first randomly started.
Are you using the ajk kernel? If you use the wrong one, you'll get that affect. FYI shostock should have mic swap kernel.

I used the default one that was in the flash able zip. Unlike most ROMs, it was an all in one package so nothing else was required.
First, you want to know if this is an intermittent hardware issue. The troubleshooting test for that is flash back to stock and observe. If the problem is still present, then it is very likely to be a hardware issue.
If not, then the problem is most likely in firmware somewhere. Since this is not a common problem, and since you have had it on multiple roms, it would probably not be due to the kernel or system firmware, so you would have to look at applications to see what might be interfering.
