My girlfriend recently purchased a Samsung Galaxy S 4G (SGH-T959V). I enjoy all the features I get from rooting, etc on my G2. I saw the Gingerbread update from T-Mobile and have installed it for her. I wanted her to be able to have root, remove bloatware and have the lagfix (voodoo, assuming it is still needed) working. As I was getting ready to find her a good ROM this CM 911 dustup happened. It's ok if she keeps the Samsung ROM, my question is where is this 911 "feature" stored? In other words, what can be done to her phone without destroying emergancy calling? I am pretty sure just rooting it is fine. Removing bloatware after rooting should be good also. I believe the lagfix replaces the kernel. If the kernel gets replaced will that break 911 calls? Is anyone working on a stock GB ROM (as officially released Nov 15) that would have root, removed bloat, and anything else safe that keeps 911 working? I would be glad to wipe the phone, root, remove bloat, (lagfix?) myself and post. I just do not know what is safe to play with. Is this just a radio issue, library issue or kernel issue? Any information would be appriciated. I would like to make her android experiance a good one that still allows her to call 911. I have searched the forums and the web but can't seem to nail down a good answer of what can be changed and what must be left alone to allow 911 to work.
911 operators are drunks anyways... here's some proof, provided from a random Google search.
This is the vibrant forum,sgh-t959 not t959v... very different..
From my understanding, cm7 is the only one with the 911 problem (and any rom coming from cm7)
. Stick to samsung roms and your good. Also the 911 thing isnt the end of the world.. you call them, they cant hear you.. hang up and theyll call you back

Ah, since the download for the updater said "Vibrant" (offical from Samsung) and the model number is so close I assumed they were mostly the same. I see now there is a S 4G forum. Sorry for the mix up. I would assume this phone could have the same issues if CM was ported. Currently it is listed as not supported. I'll move to the right forum and dig some more. Sorry for the waste of space. If anyone knows if these are affected by the 911 issue feel free to chime in. Or if a moderator wants to move this to the othe forum feel free.
Thanks
Lol the waste of space is no big deal and your right, id forgotten that they call yours the vibrant 4g. But still the two phones are very different hardwarewise, idk why.

You cant use vibrant rom. Both phone have different hardware. BTW you know the T959v 4g have Official Gingerbread.
Hello, I've flashed the Cyanogen mod for my Samsung Galaxy S2? I've been using it, it works fine.
I'm wondering, do I need to flash a radio? If so, which one? I've seen the links of radios from the Wiki page of Cyanogen under Support Downloads, just don't known which one to use or if I'm supposed to.
Thanks for your help.
Radio is not changed by CyanogenMod.
If you have no call, sms or data issues then i dont think you need to change

OK, thanks for your help.
I have successfully installed this rom. I think it's the most amazing jelly bean rom for galaxy s2 at the moment. I like its smoothing and quick response. feel a bit warm at the back and the battery is losing 1% at every minute while wifi is on. Over all is great. Cheers!
Actually, I've been experiencing data connection problems. My phone works, but it won't connect to 2g/3g for internet.
Should I try switching radios?
If so, which one is recommended? Or do you just try them at random?
Thanks again
On first boot normally can't get mobile data to work because APN was not configured properly (or the list empty), after a reboot mobile data will work again. If it doesn't, then you have to key in the APN manually.
For radio/modem, since there are no changelog released and nobody know what are the differences among them, it is assumed that the latest one will be better.

first and foremost asking or recomending which ROM/KERNEL/MODEM ,is against XDA rules, since all phones are different due to various reasons , hence if u have a an issue with ur modem u have to try a cpl of them on ur own and see the one suits u the best.

OK. I'll try a few different radios. I see a list of links in the Cyanogen Wiki page of under Support Downloads.

It sounds like your apn settings are messed up. Try to reboot twice and then try. If that doesn't work, you will have to find the settings and input them manually.

I flashed this radio:

Now, the data, 3G, works great.
I've been experiencing an issue and have read several post about RADIOS on the SGS2.
I flashed my mobile with the nightly 10.2 CM and after that it started to ask me for "SIM network UNLOCK" Which I can't unlocked, thought it was the version issue so I dl a the newest one and same issue, I tried the ICS stable 9.1 and same issue.
I've read something like radios on the CM support part. Which I dunno where is it yet . If I need to flash it and u guys can help me out to pick up the correct one I'll appreciate it. my model of SGS2 is the i777 from AT&T.
May I install NELP on my CM 9.1? how? where can I get the files to do it?

What phone do you have? This is the thread for the i777 S2 variant, and at least one of the modems you mentioned are for the i9100 variant (don't recognize the others you list).
You can only use modems designed for your device, so if you have an i777 see the link directly above your post.

Sorry, wrong thread. Hadn't time to ask for delete my post :\
I have a Samsung Galaxy SII, the i777. I have rooted it and loaded ShoStock3. I love the ROM except I'm having trouble downloading apps from Google Play. The research I have done suggests that I need a better modem. I have downloaded and flashed six different modems. Each one just as slow as the last. I'm in Salt Lake City, Utah. I know that the location can have something to do with the modem as well. Does anyone have a suggestion on which modem would work the best? Also, if you happen to know that there is a separate problem and that it's not the modem, will you please let me know? Everything else seems to load fine, it's just trying to load apps from the market that I'm really noticing it is really slow. Thank you everyone in advance.

Modems are good in different places. What's good for me might be awful for you. Have you done a speed test?
Sent from my SGH-I777 using xda app-developers app
You've already flashed 6 different modems, you should know by now which one is the best for you out of those 6.
If you don't like them all, try some more and pick out the best.
Have you tried KH7 or LL6?
Side note: why can't you use Wifi for Google Play?
You are I assume flashing modems for this device right? I only ask because obviously the i9100 modems wouldn't work for us. (And I'm pretty sure calls don't work with them) also, if you are flashing all these modems and they ARE for our device, and NONE are working properly, I would look at a fresh flash of the rom of your choice wiping everything again or going back to stock to eliminate hardware error possibility.
I did verify that they were all for my model and network. None of the six were any better than any other. I also noticed none of them worked on the 4G network. I tried to download an app to do a speed test but after 30ish minutes waiting for it to download on each modem so I could test it, I gave up.
Shoman94 changed to UCLL6 modem on his latest build. Are you using this one now?
Or you can select all the modems from here:
http://forum.xda-developers.com/showthread.php?t=1336958
They seem to be working OK, at least for me. I have tried at least half of them although I am still running ICS (CM9.1), not JB like you.

In the Settings of ur phone, since u r runnin SHOstock 3, do u have the Mobile data box checked under Data usage ? And do u have the "Set mobile data limit" box checked under Data usage (this could hinder u) ?? And under More settings/Mobile networks is the Network mode set to something Other than the "GSM/WCDMA (Auto mode)" (this could also be the problem)??

So, I un-rooted my phone but from what I understand, even doing that won't re-set my modem. It's still working slowly. My biggest fault here was not doing speed tests from the beginning and not noting down what my phone came with. If I could find what modem my phone came with, I would root and load it back on.
I really appreciate everyone's help and suggestions.
Is there anyone in Utah on the 4G version of the SII that could tell me what their modem is?

Hello people,
For the past few months I'm having this issue which I find extremely [email protected]!!
Every few minutes, my phones just loses internet connectivity - the 3g signal appears to be normal during all the time, thing is, whenever I try to use any internet application - it just hangs. and then, after a minute or so, connectivity is back(again, for a few minutes).
I have tried flashing so many versions of modems - some improved it a little but most of them didn't help at all, or even made it worse.
Hopefully someone could help me with that as I'm that close to give up on this and buy a new phone.
Thanks in advanced.

Which firmware are you running on your phone? What modem do you have right now and where do you live? Do you have problems with all apps that use internet-connection? Do the problems dissapear when you use wifi?

I live in Israel, bought the phone in Thailand.
I tried flashing all available Israeli modems(from various cell phone providers) - none helped.
Problem disappear when I move to WiFi - as 3g connectivity moves to background...
Thanks.
I assume you've read the Rootbox threads to see if other people experience signalproblems?
Did you compare the connectivity with other roms? Stock-based roms for example...

That seems quite weird.. The only thing I can come up with is 1) a hardware problem, or 2) you live in an area where the signal is crap

If you've only tried flashing the modems bundled with stock roms from Israeli carriers, you haven't done nearly enough. There are literally dozens of modems available, you need to start flashing as many as you need to. This isn't going to fix itself magically.

I haven't flashed only Israeli modems but others as well. I've tried around 20 so far...
Question is, which direction should I choose? should I look for Thai modems or IL?
That depends. I know Israeli carriers sold (still sell ?) the I9100T, are you sure you don't have one of these ? If that's the case, I'd be trying modems bundled with roms released by the Australian & NZ carriers which sold the I9100T (I have one), and yes, the Thai ones as well.
If you do have an I9100, then keep trying any/every modem you can get your hands on. If it's not a carrier-side issue, this is really all you can try, unless you want to start messing around with RIL's as well. I've not found any difference in connectivity doing this personally (tho many people have) but if you get to the point of trying every single modem & you're sure it isn't a carrier issue, you might as well try. But I would leave this till last given many people find their connectivity messed up even worse by flashing an incompatible RIL.
Hi,
Search everywhere and still stuck!
This is issue that I have bee trying to solve on the 'android-rsap' forum, but am completely stuck, so by posting here I am hoping that someone can shed some light on what is going on.
Link: forum.android-rsap.com/viewtopic.php?f=32&t=871
In short, the device is a Samsung Galaxy 2 (XEU), and the bluetooth rsap functionality works fine with 4.0.4 (I9100XWLPT) but when I upgrade to 4.1.2 (I9100XWLSW) it no longer works at all. What is most weird is that it seems to be only my handset that is affected, it does not seem to be a universal issue. :roll eyes: What could be specific to my handset that stops this functionality working as it should?
I have been going back to 4.0.4 and upgraded to 4.1.2. many times now, via OTA, Kies and Odin, same result every time, sadly. 4.0.4 works every time, 4.1.2 has never worked with rsap and my car
What could be specific to my handset that stops this functionality working as it should? I have tried root'ing the handset to do more testing and to try the rsap app from Google App Store, but that has the same issue. Could some of the radio software be wrong? or?
Picture shows Kies upgrade screen and the 4.0.4 and 4.1.2 versions I am getting.
Any hints would be appreciated.
Regards,
J.

Ok, So I am a beginner with hacking my Samsung phone, this is mainly as I use them as phones, and want to rely on them. Before I had encountered this issue I had not even rooted my phone before.
I would really appreciate some help with this, this is an issue what is well beyond me, as in my view, what I have done ought to have fixed it. If there was a firmware issue, my reload should have but it back to 'factory default' .
As for going back to 4.0.4, well it works, so it must be a baseline for something, it proves the radio and bluetooth stack is capable of doing the right thing.
I think I need some pointer of getting my had set back to completely stock PDA / CSC / PIT, but don't know how to do it, or where to get the parts, to date got the firmwares from SamMobile... Any help would be appreciated.

The firmware specified by Kies (the one in the picture you posted) is your region specific firmware, just search and download the firmware from sammobile and flash it if you want to go back to stock, gastonw was suggesting you to try a different version of jb like xwlss, xwlsn, xwlsw, etc... If it's common to other jb versions then probably Samsung removed proper support for it, it's not the first time they have done it, like for example they completely removed action shot feature in stock camera in jb(this is there in ics).
Edit:If this problem is specific only for your s2, you might have to try flashing different firmware.

I have tried a completely different firmware, and it behaved just the same. The odd thing is that there are no other reports of users having issues with the rsap application on a S2 with JB, so the support is on there (the app provides the stack if it is missing), but the app does not work either so it looks like it is my handset that has issues. I just can't figure out what to do to fix it. There is one thing that could be at play here, I did have a flailed upgrade from GB to ICS (4.0.3) where vibrate stopped working. It was sent to Samsung for repair, not sure what they did but I suspect that the just flashed the phone with a new version of the same firmware. Could there be something there that still causes issues?

HI,
Took a little time to get the phone back in order and then to go an do the trace.
Not knowing what I am really looking for, but it strikes me that the bluetooth stack looks to just be giving up...

Hi all,
Well, today I managers to briefly borrow another S2 handset with JB on it. This other handset has the same issues that I have, so this must be something in the packaging of the Bluetooth that Samsung did - but I am guessing here.
Any clues would be appreciated, although I think I am fighting a loosing battle here... (works with an S3, so I should go and upgrade! at least chapter now that there is the S4 - but I like the form factor of the S2 better)
Regards,
J
I can't find anything that can cause a reasonable problem in your logcat, since you tried it out with an other GT-I9100 running JB and reproduced the problem, my guess is as good as yours.

Well, thanks for looking anyway...
My thinking on this is now that as it works with newer cars and only the older ones that now have issues, it must be a version issue, i.e. the version of the bluetooth stack is not the one it should be. It would be interesting to know if there is a difference in the version of the bluetooth stack and the rsap daemon between the S3 (which works on JB) and the S2 (which does not). Would that tell me anything interesting?

J.
Your issue is directly related to 4.1.2 (and newer) versions of Android having changes to what's known as a2dp, or Advanced Audio Distribution Profile. Supposedly, these failings with Bluetooth connectivity of our blessed i9100 are fixed in Android 4.2.2, but unfortunately this version has not yet been released for it (and before anyone says otherwise, I dare them to show me where I can get the ridgey didge true blue real deal Jellybean 4.2.2 for the i9100, especially when sammobiles - the number one place for Samsung firmwares - don't have it for any country on the planet)

HI,
I was not aware of this, and are you saying this is specific to the S2, so the fact that is works with an S3 on 4.1.2 is irrelevant?

well, I've been researching this since 4.1.2 came out, and it isn't an issue only experienced here in Australia. Google is a great resource, go for a surf and you'll find out more...

Well, my issues are with specifically with rsap, not really A2DP, but if it affects the whole stack, this could be an issue.
To illustrate: I have 2 cars, one older, one newer. With the newer car all is well, and it works at is should (as far as I know) The older car was working pretty much with out issues on 4.0.4, but refuses to work with 4.1.2. Both cars rely on rsap.
Not sure this helps, just wanted to illustrate the problem that I am trying to solve.

Maybe I am overly cautious here, but in my case it works just as it should with an S3, no issues at all, for me it is the S2 with JB that has the issue. And the functionality that does not work does not go near the A2DP libraries as the phone becomes a bluetooth SIM card for the car to access (which is rsap)
There must be others out there that also have this issue?!?
