I just updated my E970 to CM 11, and everything appears to be working great. My only issues so far are these:
1) I can't hear anybody during voice calls.
2) The signal appears to be slightly weak? I haven't had the phone for too long, but my mobile network signal appears to be slightly weaker than when I was on JB.
I have read that one way to fix the issue with the voice calls is to flash a hybrid radio, but I have not a clue how to do that. Could somebody please offer some assistance? Thanks in advance.

There's a thread in the General section that discusses the hybrid modems for tmo with links to them. You flash it just like flashing a rom.
As far as the signal strength, stock bars are typically higher than custom roms due to custom giving you a true reading and stock/carrier fudging theirs.

Received my SGS2 on 29th June and ever since it start having emergency call syndrome (out of blue not receiving any network signal).only after reset, it regain signal and same story goes on till date.
To overcome this prob,i tried these:
- factory reset 3 times
- manually choose telco/network carrier
- update/flash firmware (stock XWKF1 -> XWKF3)
so for these only reduce problem's rate to occur.PLease,help anyone?
Is your sim card active ?
Hi
I have the same problem as yours (i thought i am the only one having this)...out of the blue the phone changes to the emergency calls Only status....
it is very annoying specially when you are expecting an important phone call and you discover that the phone cannot receive calls
it became a habit of mine to keep checking my phone every once and a while, and when spotted i restart my phone and this brings the phone back to normal (Normal for a day or two of course).
Can anybody help with this?
SGS2 GT-I9100, Android: 2.3.3, Build: JHKG2
First of all I would download a newer firmware. If that doesn't fix it you should probably just return it to Samsung for replacement/repair.
Actually i have flashed this Israeli ROM (it is an Orange official but leaked ROM) about a month or so and it supports Arabic, English & Russian (exactly what i need) that i have no complains about so far except this emergency Calls issue and i am not so fund of rooting etc so i don't know where i can find another ROM (official not cooked ) that have the same languages supported.

What is your signal strength when it changes to emergency only? Mine does that during very weak signal, I found it's because it can only receive GPRS singal which is from another carrier when my own (HSPA) can't establish connection.

frankly i didn't check or notice such thing, but the moment i installed my latest ROM (GB/JHKG2) i have noticed that the signal strength is very week especially indoors.
thinking off and analyzing this situation i have a confident opinion that the problem i am facing is related to the ROM i am using (GB/JHKG2).
i am thinking of flashing a different Kernel to this ROM and see what will happen

When you installed a different rom did you flash back to your original telcos baseband? This makes an enormous difference to signal strength.

I am admittedly a noob when it comes to Android phones. I have had my i777 for a few months now and have successfully bricked it more than once. Having said that, I have found that the answers to my questions have always been on the board somewhere. I am having troubles figuring out where to go with this portion of the issue though. Having tried several different ROMs for my phone, I keep having the same issue. With any ROM, other than stock, I miss phone calls or text messages when my phone is locked and on Wi-Fi at home. If I'm out and about with my phone in my pocket and locked, it works normally. But, if I'm at home working at my desk and the phone is locked, I will not get text messages or phone calls. Notifications from apps like CNN continue, but nothing from the mobile network. I have followed the guide to return to stock and built my own jig that worked to reset my flash counter as I flashed before I read when I got the phone. (Former iPhone user that just assumed it was as easy as a jailbreak, really really dumb on my part)
I am a tech geek. I follow instructions well. I am sure the problem is with my phone and not the ROMs. My question for the forum, is where to begin troubleshooting the issue. I want to be able to use these ROMs.
Some info that may be helpful:
Baseband: I777UCKH7
Kernel: 2.6.35.7
I have tried the following in no particular order:
UCKK6-SHOstockV1.9.2noWipe
Serendipity_8.2
update-unnamed-v2.2.1-full
ICScrewD_2.1
TurkbeyRom-v33
Each has individual issues that I can deal with and learn to fix, but the phone issue I, obviously, cannot get past.
Have you set the phone to keep the wifi active when sleeping or locked?

No I have not. Does the wifi connection prevent the cell network from connecting?
cell network shouldn't disconnect at all if it is, swap it out could be bad phone. Also what is your signal level at your desk at home? Low signal normally causes missing of messages.

No, it doesn't.
Do you use any 3rd party apps like tasker?
When did this issue start? Perhaps there is an issue with the tower that serves your home. How strong is your cellular signal at home? I believe text messages (except MMS) are sent over the cellular network. Your being on wifi shouldn't matter (does being at home with wifi off and the phone locked still cause issues?).
I can't imagine other ROMs causing issues, though. If anything, they would mess up your data network only if they had the wrong APN settings for your area (for example, for a while, people using Unnamed didn't have data issues, except for a few like me who lived in certain areas with Cingular towers). Or maybe the stock modem files are better for you than the ones provided by the ROMs?
Maybe you have an old sim card that somehow has issues? You should be able to get a free one from at&t. Do you have another phone that you can test it with?

I keep a minimum of 3 bars and live near the center of a large city. As stated in the op, this is only happening on added ROMs never on stock. I have again reverted to stock (+root), since the op, and confirm that I am getting messages and calls at my desk at home with the phone locked.
****************************Edit for SoCaliTrojan post********************************************
I do not have any additional task managers installed, I've just always used the one built in. As for the SIM card, I am using the one that I got with the i777 at upgrade and get the 4G network when not on wifi, so I think I can rule it out. My wife has a Note that I have been drooling over, guess I will have to "borrow" it for "testing" when she gets home from work.
Also, I notice I am on baseband KH7 with Android version 2.3.4. I see mention of KK6 and 2.3.6 on the forums. I have avoided flashing the baseband, when possible, to keep from possibly bricking the unit. Is it possible that upgrading these could resolve the issue?
That is a very weird problem. Only thing I can suggest is compare the APN settings in root with a custom rom's settings. They should be identical, but check anyway.

Then it isn't connecting to 4G networks.
It's labeled as "4g" but really just multiple 3g connections to give you a faster overall speed. But you might want to just try getting a new sim card at your AT&T store, if that doesn't work, try a different modem (like KK6) the whole list/downloads are in the development section.

I made AT&T upgrade me to a n LTE sim card. Our phone disent have LTE but the newer sim cards supposedly will make your speeds faster when LTE does come to your area due to it pushing HSPA+ faster than enhanced backhaul.
You said you live in the center of a big city maybe being surrounded by a lot of tall buildings could be causing havoc on your cell reception.I know at my work I can send and receive messages and calls everywhere except our breakroom but everyone else's phone works fine in the breakroom.

If I was wanting to pit a new modem on my sgs2 att phone what do I need to do?
Sent from my SAMSUNG-SGH-I777 using XDA
Just sold my phone to a user on swappa and he's having problems with placing phone calls or I should say hearing audio over the handset. I used it with AT&T before the unlock so I didn't have this issue and have flashed numerous roms to the phone successfully.
I am careful to wipe the phone data etc + dalvik cache before each rom install or refresh.
I read on an andadtech forum through Google that this could be the radio and see that there are several to choose from, including the Nexus 4 ones based on an xda forum post. Any recommendation from a power user with a good reliable radio or possible combo I can test for him? He prefers to run 4.3 as the Android version and bought the phone knowing its no longer stock.
The phone has no abuse or harm in any way as its mint and was handled that way. Any help would be appreciated.

Im having the same issue, tried slimbean and cm10.2 both with no audio on either end during calls unless you put it on speaker phone. Sim unlocked running T-Mobile. They haven't refarmed my area so the best I can get is 2g unless I go into town I can get some low signal 4g. Stock phone works just fine...
I am living same problems.
I was having audio issue with my OG for the last few days. I just recently switched from att to tmobile and also from stock jb to CM10.2 nightlies...no call audio, speakerphone was quiet. Today I flashed the hybrid .33/.84 radio and all seems to be working well again.
i have cm11 on my e970 and whn i try to call nobody can hear me and i cannot hear them , what is the problem. Do i need a new radio?

I have same problem with CM10 and CM11 on E980 ... phone calls coming in and phone calls going out.
When I restore ATT standard rooted install 4.1.2 ... it all works again so not a hardware issue.

Yes, some people (all?) have problems using the LGOG with T-Mobile. I thought I bought a used lemon until I did some poking around here. A hybrid radio solved the problem for me. No link handy, the file name of the one I used is LTEhybrid33-54.zip. Some folks also report success with LTEhybrid33-84.zip, so look for one of those. They are simply flashed through recovery, TWRP in my case. Search for those files, or radio threads and you'll find what you need.
Or switch to a AT&T or another AT&T-based provider, like Straight Talk. I am SIM unlocked, using SImpleMobile (T-Mobile's network), and a hybrid radio. Probably switching to Straight Talk soon, due to AT&T having better coverage at work where I do more streaming and whatnot.

Did a really stupid thing and now im in serious trouble.
After flashing a E977 radio I had signal and netwrik(could make calls and receive messages), but had a few issues with the autorotate, so i decided to flash back the JB radio. turns out after that i get no signal and the Micro sd not inserted icon. Tried flashing different radios with different mako radios and the hybrid ones from the general section with pretty much the same result: I get bars but no network, cant make calls or receive/send messages. Sometimes though I manage to get a very weak network signal(1 or 2 bars) but it goes away very quickly.
Flashing JB or ICS modems result in no bars and the sim not inserted icon. Tried LPGNST back to ICS, had bars but also the no sim icon.
Im stumped here, so any help is appreciated.
