sorry if wrong place to post this, but basically I have been racking my brain trying to figure this out.
i have an S3 mini (like that isnt bad enough)
and i decide to root, flash cm10 (mcklaw golden beta2 and enjoy all the perks of cm10 and enjoyed the phones greater usability for at least 1 day,
suddenly i get the old signal drop issue, so i figure my phones modems playing up, the baseband is XXXX and im convinced i need to reflash it, so i do, (data wipe/wipe) and the same thing happens usable for a few hours, but after the third time i realise this isnt a long term solution.
So i look around for various solutions, im pointed to the efs folder and .nv_data, to which i say to myself 'im glad i backed that up!'
...i restore efs and i see everything is normal however i dont seem to have nv_data at all, (im not convinced it was ever there?)
more to my surprise, i have IMEI, I check *#*#4636#*#* everything looks ok, the radio seems to function and i have everything but baseband,
signal comes and goes, sometimes its fine 3g etc other times nothing
im just asking basically does it sound like i have lost my efs folder? and any ideas what i could try to narrow down the issue, or possibly resolve it?
thanks alot for your time,

Hello folks of XDA,
I came here because I have not heard any response on the MIUI forums and UI guess is because the community over there is not as big.
Anywayas, I flashed 1.8.5 MIUI, and I suddenly could not see the screen after I dialed a phone number. Then I also noticed that I could not see the answer screen when someone called me.
Everything else worked like a charm, so I thought to myself, well, maybe I have not been back on JFD for a while, so I went ahead and restored the phone back to stock, follow even the MIUI procedure for the massive JFD restore, and it does not matter.... Any Rom from stock to MIUI or CM7.1 all give me the same problem or an app force close, of phone freeze. I can hear the person on the other side if I call, but there is no human way I can answer the phone.
I believe the phone.apk might be the problem, but after trying to do all kinds of factory reset and format, I am still in the same place.
So my first question is, is there a way to fully format the phone and put it with stock apps. Like out of the box? using CWM gives you the option to format the mount points, but I am afraid to format everything and then have a true bricked phone.
Any comments suggestions, questions, please let me know. I been working on this for 2 days now with no avail.
Bump. I have no phone, so it is very frustrating
So I called tech support and see if they had any idea of what could it be. in the end I am back on stock, so what more harm can I do to it right? Well the tech said something that really leave me thinking. He said that the proximity sensor could be damaged. Now that makes a lot of sense, in the end the phone is already somewhat old and I have had my mishaps dropping it from time to time, but luckly no scuffs on it. What do you guys think?
This though is gonna mean that I have to go get me a new phone today ....
Hi,
Sometime today I lost my phone signal on my SG2. I'm not sure exactly at what moment as I first noticed that I had a couple of bars but no 3G when I tried to browse the web. So I restarted the phone but to no avail. Since then I've lost all bars and can't make any calls either.
The only thing I have done today "out of the ordinary" was to connect to the phone using Wifi File Explorer to transfer a file, which I tried to connect to without being on a wifi network by first trying the "Wifi Direct settings" in Settings, which didn't work, and then by tethering by Wifi which worked. Maybe some setting got stuck in the process, but I'm not sure since never checked if it worked right before and after.
If anyone has any idea what could be wrong please let me know, as I am literally without a phone!
I recommend downloading http://www.androidzoom.com/android_applications/communication/no-signal-alert-pro_fyyo.html this will definitely be of benefit to you if your suffering from signal problems, it has been of good use to me.
Check your IMEI is the correct one for your phone .If not restore your backed up EFS folder .
Or try backup data and factory reset as a first step.

Thanks for the quick replies!
The IMEI does not correspond to the one I have written down, though I'm not 100% I what have on my note is the latest IMEI; but how could that change though by itself, if my note is correct??
Also, I just saw something very strange: I turned on my phone and had full bars (no 3G though), and right in front of my eyes all bars dropped, one by one, during the course of 5-6 seconds. Something is VERY off...
Regarding factory reset: my phone is rooted (thanks to XDA!) and I have Tit.backup: can I will my phone still be rooted if I do a factory reset?
Something went probably wrong when rooting it (not neccesarily any errors) and effed up tge EFS folder.
Try to flash back to stock ROM, it might work to restore your.folder.

I should have been more clear on that, but I rooted the phone about a month ago and it has worked flawlessly since then, so it couldn't be that.
Anyway, I looked around a little and found this post:

He seemed to have had the exact same problem that happened to me, so I decided to wait, and sure enough the connection reestablished itself about an hour ago and while I was watching for it, with the signal slowly creeping back up during a couple of minutes, and several hours after I lost it. Very odd.
This surely has to be an Android bug but that only shows up under certain and rare conditions.
To be sure I made a speed test and got 4.84 Mbps/up, 1.19 down, which I guess is fine; I never did one prior to this so I have nothing to compare to.
Again, appreciate the advice!
EDIT: For posterity, I should add that during these hours, even when I briefly apparently had a (non-3G) signal, I had a notification during all this time saying that I could only make emergency call.
I'm having the same issue. No Bars at all most of the time and when I have some, it never connects to 3G, G at most, and can't load any thing at all.
Very frustrating. I have been using Lite'ning rom 6.1 for a few months and had no problems at all until about a week ago.
I flashed back to a stock rom and still having the same issue.
I've also seen the bars drop down one by one in a 5 second window, bizarre!
Anyone find a fix for this? Or could the phone be faulty?

I was on Lite'ning about 3 weeks ago and actually completely lost signal several times. Reboots and hard resets solved the problem temporarily. I then flashed Batista FH 2.4 with ICS and things were great. I'm now on GingerMod. No issues.
I don't know how it could be kernel related though, especially if you are 100% stock again.
Hi there! With SGS III being my third from the Galaxy family, I did not waste any time and flashed first custom rom the very hour I bought the phone. Everything was really great - I've been through Android Revolution, Omega, Wanam and couple more, but it all seemed too good to be true. Two days ago somethig went wrong with my data connection - I noticed it while I couldn't connect to Facebook. The "H" icon was in place and by the arrows I saw that it was "working" all the time. The problem was (and still is) that no data actually goes through. I tried different radios, kernels and roms - to no avail. I've read something about botched or misplaced IMEI issue, but checked it right after that and it is intact. To be sure I tested my SIM card in other phone and the data connection is working flawlessly. APNs checked. I'm getting quite nervous because I've only got my SGS III for three days and already it's.. Not entirely functional.
If you have any idea what this may be about, I'm happy to provide any information needed to identify my problem. Thanks in advance for saving my S III..
Sad to hear, unfortunately it seems you already tried the common solutions to solve such an issue, the only additional thing coming to my mind is to flash a stock Rom with odin, if it doesn't work do the same with a pit file or change your csc, because the last two options reset your whole user data to stock and your internal sd as well (don't forget to backup your data) it should solve it.
Maybe there is somewhere a leftover which causes your problem, good luck

Flash a stock rom with Odin and perform a full wipe *2767*3855# in the phone dialpad. Save important files to the pc first. This should fix it all. You can reroot after that and make a cwm backup of your stock rom.
-Edit- double post, Follow the above
Thank you both for your suggestions, but it seems that I'm stuck with I-do-not-know-what.. :/ Flashed stock rom and new radio via ODIN, but the problem with really slow HSDPA connection is still present. I am worried it might have something do do with IMEI after all - it seems that here http://forum.xda-developers.com/showpost.php?p=29461950&postcount=3 they are explaining similar issue, but I haven't lost my IMEI (not to mention backuping nor restoring anything). What is more, I do not only have EDGE icon, but HSDPA as well, but the connection is slower than GPRS. Damn it..
First of all,since this is my first post please excuse any noobish things that I might say.
And I have done a reasonable amount of research but was unable to find a solution and would really like to apologise if this has been asked before.
I bought a sgs2 about an year ago and since the very first day I had problems with receiving calls and even making them.
If I'm sitting at one place everything's good but as soon as I move something goes very wrong and the call drops.well if I'm moving I'll be glad to even get or make a call although the signal in the notification shows full.
Now on the stock ROM,the signal strength is about -61dbm 19-20asu but on any other ROMs that I've tried it never goes beyond -89dbm 11-12 asu.
Next I read a lot about flashing different modems that might solve the problem but no.its like nothing seems to work.(BTW I tried a lot of modems for my country and others as well and used getril also to match the ril's as I read about that in forums.)
So im really very pissed with my phone and yesterday I was researching for a solution for the above mentioned problem and came across someone having a problem about losing the baseband and imei after flashing and thanking heavens that at least I don't have that problem.
But WHAM.The same problem hit me right in the face ASA flashed a modem.
So NOW I have a ****ty network problem(please excuse my language but you have no idea what its really like)and now no imei and no baseband.
Luckily I had a backup of the stock ROM and when I restored my phone at least I got the imei and baseband but when I rebooted my phone for something,the problem came back.
This phone is otherwise very nice but I'm really having a hard hard time getting through with this and unfortunately my father won't buy me a new phone for another one year as I promised him I'd use this phone for at least two years since this was way above the budget he gave me.
BTW I'm currently using revolt jb ROM by johnhany.
I'd be really very greatful if one of you millions of geniuses could help me.
If you need any further details in finding a solution I would provide it ASA I see what it is that you might want to know.
Thank you in advance.
Moving to Q&A - Read this - http://forum.xda-developers.com/showthread.php?t=1763193
Hello sir.
Well sorry for posting it in the wrong place but were you trying to give me the solution to my problem or just telling me to post a question in the q and a forum?
Sorry for being so dumb.
Oh.My bad.just read it clearly. Sorry for posting at a wrong place.
So, without writing a big long explanation, I'll cut straight to the chase and tell you what's been done with some light background.
I woke up one morning and my network was inactive. At first, I thought it was maybe some mobile network issue. One day later, still no connection.
-Odin'd back to stock twice
-reflashed multiple roms (including all the usual formats)
-flashed 5 difference ICS modems (KA5,6,7 and KB1,5)
IMEI error popped up after a new rom flash for those that are curious, but I lost my original a while ago and just adopted a generic. Never had an issue with it affecting my mobile network. I remember having a modem issue before when ICS was in it's discovery phase and flashing roms, but nothing where the modem just stopped while it was running/on.
I just wanted to see if I forgot something before I officially sentence my phone to death. I wanna say maybe a freak surge nuked it or something. That's about all I can think of since I know my way around android. Any ideas appreciated. maybe there's a way to check my hardware I forgot about.
Thanks!
