GSM not working anymore, stuck in emergency mode

Hello all,
my Defy is stuck in emergency mode and can't find my carrier anymore (o2). Details:
- only emergency calls possible, no network found
- another mobile in my house gets outstanding connection (o2 aswell), when switching SIMs, it's still my Defy not getting a connection
- wiping the Defy has not changed anything, even with stock settings all I see is the red cross (put my settings back with clockwork recovery)
- an hour or two before this happened I was listening to music with my headphones, but between taking the headphones out and GSM failing I was sending texts
- When doing a search for other carriers I can see some (though not reliably), but not mine
- I bought my Defy via Amazon, so no SIMlock, obviously.
- WiFi, Bluetooth and GPS are all working fine, so they probably have different antennae
- I rooted my Defy, but this was over a month ago, and it was working fine. I also did not install apps or update some existing ones before this happened. I also did not reboot. It just happened. Put it in my pocket and next time I got it out there was the red cross.
In Phone Info -> Status it says under signal strength "-111 dBm 1APU". It all looks like the antenna is broken, but I didn't hit it, drop it, put it into water or hurt it in any way before this happened or the 3-4 days before. So I'm really lost here.
Anyone? Thanks in advance.

Hi. Have the defy for about a month now. Same issue since first day. Dont know whats wrong. Found out that after 4-5 reboots its ok and lasts till next reboot/switch off. So try turn it on/off 4-5 time or just download a quick reboot app and do the same to see what happens. If aneyone has any idea on how to fix this?

i get this all the time when i flash my defy thru any other rom......and thus roll back every time to stock (indian) rom.....
try flashing your phone with any compatible rom....new radios might get ure phone working

Same problem here. First time today, spontaneous, after a month of use my Defy, non rooted, never unlocked, standard noMOTOBLUR, just like as it was bought from store. Moto_Versiuo.2.34.1.MB525.Retail.en.SEA
None of these worked to restablish the radio connection: succesive reboot, manual/automatic network search and choose, succesive airplane on/off. I didn't check the signal parameters.
I thought that the SIM just burned, removed and try it on another phone and everything was OK. When put it back in Defy, the network connection was established.
The experience was very strange and my final verdict was that the SIM just moved a little from its initial position.
BUT now I realize the problem is more complex and I don't know what caused it !

I have also noticed that the sim card slot gives a little more space for the simcard to move (at least on my defy). Might be a prob with the sim card being old or something (mine is from 2005). For now i'll just try to keep my phone on (seems i finally found stable settings for setvsel, so no more unexpected reboots).
An answer from motorola's official support forum is just remove the simcard and clean it with some cloth...

This is definitely a sim slot/card problem. If bought from amazon they will oblige to change it without any money. I did the same but not for this problem.
If you think there is some problem with software, which is unlikely then flash an sbf and see if things are fine.
To begin with flash chinese froyo sbf. It is downgradable to any previous firmware you were using and very flexible.
Hope this can solve your problem. Get back on what the result is.

Same here...
My defy got network yesterday at 07pm til mid-night.
before, since 16 (11pm) til 19 (7pm) before it function again.
and now, its bloked.
i rooted my cell one month ago, then, probably thats not the fault of z4root.
Sorry about my badass english, i still in upgrade mode.
any idea about it guys ?
thnx

Problem solved replacing sim card with a new.

[Q] T-989 - No data network. Mobile Network State: Disconnected

Hi there. I own an unlocked, rooted t 989 Samsung Galaxy SII which I bought in the US. I recently moved to the Netherlands, and got a new simcard with Vodafone. The problem: I can't get my data to work.
I have tried (almost) everything, so prepare for a read. Here's the list:
- Sim card is fine, I tried it in a old phone and 3G pops up instantly
- Rebooted, pulled battery, turned mobile connections on/off, handpicked network, etc, etc, all the basics.
- Got the APN settings from Vodafone. Tried them manually, resetted them, automatically, turned it on, turned it off.
- Going online through Wifi works.
- Under settings-Status it reads under Mobile Network State: Disconnected. But I know that the phone detects the network correctly. It can distinguish between UMTS and GPRS here.
- So there seems to be no trouble with the phone being incompatible with the network. I read online that other people had NO trouble using their T989 in Europe.
- I tried inserting my old American pre paid T mobile sim card and turn roaming on. No luck.
- A lot of other people with the same problem tried to link it to Easy Battery Saver. I tried updating, uninstalling and going into its settings to find out what it could be, but nothing.
The last thing I can still try is to factory reset, unroot and try to get the phone to its most original state and see what it does. But before I triple wipe all my contacts, pictures, apps, etc, I want to make sure I did absolutely everything to try and fix this beforehand. Being a noob here, I can't post any links but I trust you I tried.
The people at Vodafone are of no help whatsoever. I hope you geniuses could help me any further.
[Edit] And sorry for posting this in General Chat. If a mod could move my question to Q&A I'd be most thankful..!

I am having the exact same damn problem! it started with being unable to send a simple text message yet having data. now it says it is searching forever

Try flashing a different radio/modem then an american one?

@decko5 Nice to see I'm not the only one, but that doesn't help us yet .
@doug36 Besides the fact that I'm running a stock ROM that should be compatible with no issues, I'm not sure how I'd do that. I can flash a separate part of the kernel? That sounds like a very tricky thing to do.

It's actually pretty easy. You can flash most radios via ClockworkMod Recovery. I couldn't find any threads with a list of Galaxy S-II radios here on XDA, but I found one over at RootzWiki for you. http://rootzwiki.com/topic/2725-radio-samsung-galaxy-s-ii-radios-updatezip-updated-20-aug-2011/
Just find the corresponding one to your geographical location and carrier (Google is your friend) and follow the steps.
Good luck and hope it helps!
(p.s. you should definitely look to see which radio you currently have so that you can download a backup of it before you go flashing radios.)

Thanks for that very helpful post! I've raped and butchered Google, but I'm still having trouble finding out which modem I should download. There seem to be so many and the post on RootzWiki gives no guidance to which is which. Any wisdom on this? I'm in the Netherlands, so Western Europe, on a Vodafone network.
By the way. I fully wiped my phone and installed Team Kang's Juggernaut 5.. No luck, same problem. What I found really, really weird is that it was instantly in Dutch. (Which is ok, I speak Dutch) But I don't remember ever selecting a language. How does it know? Besides, I'd rather have it in English .
What I did find out is that I'm still using a old firmware, UVKID, instead of UVKL1. So I'm restoring back to my previous ROM and trying to update. I'll see what happens. If that doesn't work, I'm going to restore my phone to stockest of the unrooted stocks and try and update.
If that doesn't work, I'll have no option but to send the phone to T-mobile.
I'll try the modem update as soon as I understand what I'm doing . But it does sound promising. Thank you so much for your help, it's greatly appreciated!

Hi guys,
I've updated my firmware to UVKL1, still no luck. Anybody who can tell me which radio I should try on this Vodafone network in the Netherlands?

I am from India and had faced this similer issue with many of my android phones specially with captivate and infuse.......Here what i always did to connect data network.
Just uncheck the use packet data network box in mobile network settings and try to move out from that area (say u are in ur office and going back home) and check the data in settings.
This thing has worked for me always, I don't knw if its related to the OS or to the network provider but this has helped.
Have u tried any other network sim card on ur phone ?

An update for other people that might be looking for a solution in the future. It turns out to be a clear Vodafone problem. I tried a different simcard from a different network (both T-mobile Netherlands and KPN), and they instantly worked without any trouble.
I went back to a different Vodafone store in Amsterdam, and they were much more helpful than the first one. The sales guy told me he had seen the same problem with AT&T iPhones on the Vodafone network.
I called Vodafone, and they have been very nice to me. But they haven't found a solution yet and are looking into it. They see me registering to the network, granting me access, but still my data doesn't work. They've also told me that they will let me cancel my contract for no cost if they don't find a solution.
So problem remains unsolved, but at least there's some light at the end of the tunnel. I was close to buying a new 500 dollar phone... Americans going to Europe: Beware with getting a Vodafone simcard. Sorry to the Vodafone guys, but as for now, that's the status.

So to give closure to this issue (I always hate it when people fix their problem without telling the interwebs..)
IT WORKS!
After an initial terrible experience at the Vodafone counter, the headquarter tech guys have really been great to me. So it is indeed a Vodafone problem. American phones always give them a headache. They don't know what causes the problem exactly, but they do have a fix. It turns out that when logging on to the data network, American phones (AT&T iPhones, my T989 SGsII, and some other Android devices) sent some gibberish along that make the Vodafone server go cuckoo.
The solution was, miraculously, to sign me up (for free!) to the WiFi hotspot service that Vodafone provides, and then logging on to a different APN, being: office.vodafone.nl in my case.
Hope this helps anyone who's having similar issues.

ok the issue here is that some of the t989 are vodafone and some are USA network , now the other solution is that you flash with command prompt which there is a link to that tool im going to upload from the link i got it from . its also a clockrecoverymod , but this 1 asks you for deleting data user on the device and also resets the network includes USA/overseas though if your not customed roms
or any hacked roms , after flashing this device your basically removing any unwanted apps and cache that are hidden during network searching will be fixed bugs , put the simcard in slot but make sure that is a 3G/4G accounts, than its going to reboot the device automatically , it should be searching for service and also will be a circle with a slash on it where the service bar usually is , just wait about 1/2 hour to an hour maximum time let it do its thing , ok whats happening now to the phone is that is thinking with android network with usa and overseas market apps comparing both carriers network also gets the proper address for the custom rom or original kernel, froyo either 1 will get the correct network address and / VPN / and also will be adding both T-mobile/AT&T choose T-mobile dont go for AT&T cause it will research network configuration plus the phone its not unlocked for both its just a network passby to get correct WPN/VPN/clockworkrecoverymod .

Where is an fix?
Sent from my SGH-T989 using xda premium

@#11 That reads like gibberish to me
@#12 I think I posted a fairly extensive report on how I fixed this...?

[Q] suddenly can't see any mobile networks - Baseband "unknown"

SYMPTOM: can't see any mobile networks
BACKGROUND: I've been using htc one x for a month now. Initially on three, but their signal was unusable at home, so sim-unlocked and switched a couple of weeks ago to giffgaff ( a virtual network on top of the UK o2 network).
All has been fine, until today. I sent a few texts & calls in the morning, and mobile data was working. Since then, I can't see any mobile network.
wifi is fine.
Search Networks pops up "Error while searching for networks" and finds none.
No software changes of any sort since last successful call. No changes at all today, at least until I tried to diagnose the problem.
Running stock rom, with the WW update of a couple of weeks ago (1.28.771.9.CL56522 release-keys) -- neither S-OFF nor unlocked bootloader.
Nothing obvious to me in the normal or radio logcat logs.
The only thing I did after the last successful call was to run sensorly to try and map a trip. I've used this before without any problems. It got no connection but I thought nothing of that. I've since uninstalled it just in case it could somehow be interfering with the radio.
THINGS I'VE TRIED:
No, the airplane mode isn't on, and mobile is. I've toggled airplane from settings and power switch, many times
recreated the APN
checked other phones - yes there are a number of networks visible
tried the original o2 sim - same problem
safe mode
cold boot
reboot, reboot, reboot
obviously I haven't pulled the battery...
turned off wifi, in case it was somehow interfering
HTC diagnostic tool
factory reset
confirmed imei is not blocked
Any ideas? Bearing in mind that I'm looking for something which can happen spontaneously.
Interestingly, while writing this I've just noticed that Baseband version shows as Unknown. That worries me - is it possible that my radio partition has spontaneously corrupted itself?
I did speak to 02 support - they said to take it into a shop for warranty repair. I don't want to try a custom ROM just yet -- not when I might have to use the warranty. But is there any way to force it to reinstall the stock rom (preferably not involving windows)?

I have the same problem as well and flashing custom roms did not solve it for me. But for me even the IMEI number is shown as UNKNOWN...I haven't done anything special to get this issue, one day when I woke up the phone could not connect to any network.
I have tried a lot of different methods but with no success. I don't think we can do anything about the baseband without S-OFF.

If a hard reset fails, then it's time to think about returning the unit. Either get a refund or get it replaced.

This may be irrelevant; but I've had this happen to me on my GNexus. I solved it by going back to stock and it just fixed itself overnight.....

my HTC One X did the same after about 2 weeks. Gave it back to supplier, waiting my replacement.
Even tested with a different SIM card, did a hard reset. Problem stayed the same.

Im curious did any of you find a resolution to this? it happened to me a while ago but yet to fing a solution. HTC refuse to fix under warranty because it is unlocked.. i am currently waiting for the next official update to see if that fixes anything but the way things are looking that could be a while..

It sounds like a fault, probably the radio chip has just stopped working, no software is going to repair that. If it was a software problem, there would be hundreds or thousands of people all having the same issue.

[Q] Network issues

Hi everybody
I recently purchased a galaxy s2 Tmob but I have network issues
When I insert my SIMPLE MOBILE sim card, everything's fine, I can do phone calls, send sms and go online with data (but internet is slow), after few minutes the internet connection becomes very slow and then drops; followed by the network (the phone doesn't find network anymore)
The network comes back only if I restart the phone and it goes again
When I got the phone it was android 4.0.4
I tried to update with Samsung Kies, but a problem occured and I used "Kies recovery mode" to do the update
Finally the phone was successfully updated to android 4.1.2 but still the same problem. I did a factory reset+data deleting through settings and I still have the network issue
After some researches on the forum, I saw terms like "stock rom" and "radio" always mentionned where people had others network issues but I don't understand all that
Does somebody know how to fix it?
Thank u

hi
I found something to do about that
I saw on certain posts people saying that network problem can be fixed by flashing last radio version
so, that's what I did and by the way I rooted the device to flash SGH-T989_UVMC6_radio.zip
The problem seems to be solved but I'll wait to see if the network won't disappear again

Again, network is gone after 30 mn
pls someone can tell me what to do to solve this problem?

Where did you buy your phone? It sounds like it has a bad radio.

I used craigslist
when I bought it, I tested it with my sim card, there was no problem
U mean by bad radio an hardware problem?

hello, does someone have a tip for me to get my problem solved?

[Q] S3 T999 stuck on EDGE

Does anybody know how DocHoliday77 solved the S3 T999 stuck on EDGE problem? I've tried PM, but he seems to be gone. My T999 works fine in every way, except for being stuck on EDGE.
My IMEI is not 0. I've entered my IMEI on T-Mobile's IMEI verification web page, and it says it's good to go.
I bought 4 of these exact same phones several months ago -- kept one for myself and gave the others to my kids. Mine had the infamous problem where the seller had restored it to stock, but the flash counter was 1.
I recently tried a couple things to solve the EDGE-only problem. I first tried flashing CM11, thinking it might have better controls and better luck, but nope -- same problem, EDGE only. After that I decided to follow the thread about how to completely unroot, reset the flash counter, and get completely back to stock. After doing that, my device status began reporting as "official" (where before it had said modified), and I immediate got the OTA update from T-Mobile to push me up to 4.3.
Even after that, I'm still stuck on EDGE. If I try changing my network settings from WCDMA/GSM (Auto) to WCDMA only, I get no signal at all.
I tried the NV reader/writer to save my IMEI from location 550 (decimal) and then write it back; that didn't do anything either.
Since the other identical phones I gave to my kids do not have this problem, I know it is not my network nor my local towers. I also got all 4 of our SIM cards at the same time from the T-Mobile store, so I don't see how it could be the SIM card.
I suppose it's possible that I just have bad hardware, but it would be strange that only the 3g/4g part would be bad. It seems like something is just screwy with the firmware somehow, and I don't know how to get to it or where else to look.
Since I can't seem to reach DocHoliday77, can anyone point me in the right direction?
