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.

Phone keeps reverting to Emergency Calls Only

I'm running MIUI on my UK Desire Z, on a T-Mobile pay monthly contract. The phone frequently goes into Emergency Calls Only mode for no apparent reason, then goes back to normal in a couple of minutes.
Has anyone else had this problem?

I have not had this problem, but I believe that once the phone goes into Emergency Mode, it should require a battery pull and/or a reboot to return to a normal state of operation. Perhaps try a battery pull? This is supposed to be a security feature so that if something happens your location can be tracked... or so I've heard.

That's the strange thing - it rectifies itself after a minute or two WITHOUT requiring a battery pull or any other kind of intervention. I'm just wondering what puts it into this state in the first place???

I think it may also be a sign of a bad SIM card. Actually yeah, I don't know why I didn't think of that first. If it were me I'd try a replacement card and see if that resolves it.

Trying a "replacement card" sounds easier said than done. Do phone companies issue replacement SIMs without the need to port the number from the original SIM?

Yes. SIMs go bad from time to time, and they can easily issue you a new one (keeping your existing number). Not sure about UK, but in the US, the easiest way is just walk into your carrier's store, and they can fix you up. Some carrier ware technically supposed to charge you $10-20 for a new SIM, but they will often overlook it. Really, the things cost close to nothing. And the SIM simply enables you to use their service, and for them to make money off of you. So why not give you one for free?

The phone moves to 'emergency calls only' intermittently when switching networks or turning in/out of airplane mode, etc.. if its staying in that state, your phone is either having trouble keeping network connection, or isn't properly registering on the network. Id check to make sure your APN's are correct and if they are then id go about replacing the SIM possibly.

Have the same problem, but need to reboot my phone to work(( Have no idea except bad SIM-card. But it's registered to the person I've never known, so I can't change it((

I'm having the same problem in uk on orange (signal sharing with tmo).
As I wright this I have 1 bar but says SOS. Bam.... 2 bars orange. It seems to be when it would normally switch to tmo. Been like it for 48 hrs now.
I'm going to give it another day or 2 then investigate further if needed. Could be they are doing network maintenance.

it might due to soft bugs or sim or singal issue. Need more info for investigation.

[Q] I9082 self off or self restart

Welcome. I have a little problem with SGD. Phone often turns itself off or restarts itself (at least 1-2 times per day). It happens even if is not used (I can hear the sound then restart). I have the original ROM XXAMCD region of TPH but I use the Polish language. Does anyone else have this problem?
PS. sorry for my english

Install latest firmware and check if the exists or not. Last solution is service center..
Sent from Gt-I9082

Your firmware version is old. The problem will disappear after system update.

Which ROM I can flash to have polish language? May it be XXAME1 from BLG, EUR or SEB?

Some answers? Please

I did not wait for answers, I did it, flashed rom XXAME1 EUR and since last night there is no restart (for now)

May be it restarts because you phone gets heated up.

No, I have no root. Now I have the newest stock XEO ROM but this problem still repeat but occasionally. I observe one thing. My phone still works with 2 SIM card:
1. 3G internet only (Aero2.pl)
2. 2G talks, SMS, MMS (T-mobile.pl)
Always, when I hear starting sound and I get phone it was hot on the rear panel (see below)

and I don't know why. For few days phone works only with one SIM card in first slot (3G T-mobile, card 2 is off) and no offs or restarts. Maybe when phone works with two cards I must unmark in Settings->SIMcard menaging-> recieve calls by other simcard when data are used"?
PS.sorry for grammar

There is absolutely no waya phone restarts becausee of usins sim 2
Try enabling 'do not keep activities' and 'limit background processes' to 'no background processes' in devoloper options.
also clear RAM often by holding the home button and click the 1st button and go to ram no click clear.

solution
Did you find a solution? I have the same problem. If you could write in prv in Polish...

Now I have ME1 ROM and restarts are sometimes, not so many as earlier, but happens. Indeed - it restarts when the phone is hot. Maybe it happens when the phone is synchronizing data? I am nor sure. But it is not burdensome just now. After some weeks (months?) I can tell that this phone is not top of my dreams (my last was SGS II), but I can't found at this moment nothing better then this one, which works with two SIM cards and WCDMA 900Mhz (AERO2 - 3G internet mobile operator works in that frequency for free in Poland). Few weeks earlier I have used ZTE V970 - it was good phone, but not so good like SGGD though some drawbacks.

Same Issue but I don't see how to implement the suggestions being an end-user
I have the same problem (random reboot) but cannot see developer options anymore (I saw it in the past but it seems Samsung locked it, i don't know).
I notice it happens more when I am driving and using Waze or playing music thru Bluetooth in the car speaker. Maybe it gets hot but I am not sure. But my concern is many of the suggestions I cannot implement bacause I am an end user that has not many tools or skills to play with the phone. I am sure I have the last firmware, but the phone keeps rebooting once or twice every couple of days...
It is annoying and makes me feel like I should have bought a proprietary solution like Apple...

This is the worst brand of smartphones ever... Samsung Galaxy grand should be shut down!!

[Help]
Hello everyone... this is my first time to post here and im also a new member in this forum and for
information about my self is
im just an ordinary man and dont have some knowledge about phones, softwares and etc. ..
im just hoping that there is someone who can help me regarding about my issue so this is what happens.
I have a phone samsung galaxy grand dous GT-i9082 i have this phone for about 3 years but my phone suddenly not working
properly. There is sometimes my phone works when there is simcard and when days pass it suddenly off and it will stock
in the logo Samsung galaxy Grand Duos GT-i9082. when i off my phone and i will remove my simcard it will work properly again
and then days pass it will do the same. at first it is just ok for me in that rotation of my phone but in this month it gets
worse..when i only put one simcard in sim 1 the same will happened on my phone it will on and in seconds it off directly and so on..
but when i put 2 simcards it will
work properly again and days pass my phone same as always..
i tried the method of factory data reset many times but my phone is still the same. last week im thinking that maybe my phone is outdated
for not upgrading it so i came up my mind to watch a tutorial on how to upgrade my phone jellybean to kitkat. i just flash a new ROM and follow
the steps in the tutorial but the files which is in the tutorial is not working everytime im doing the steps and other files
which website he gave is in error..so i download
another files related to my phone not just 1 but 3 files for my phone just to make sure which one is working.. and last night it work!
my phone got upgraded i got it to explore it for about 30 mins.. but so sad after that it off and it is still the same as always with sim
and without sim
... sorry for my bad english guys.. if there is someone
who can fix my issue im gladly to thanks a lot for your help have a good day everyone!

I too had this problem. It is probably your battery. Change it. Your battery is probably degraded. It cant support the power requirement of mobile hence the mobile shuts down.

Change your battery.

SIM card works only few minutes (Any ROM)

Hello!
I have problem with SIM card in my d855.
I'm on Cleanrom from September, but a week ago SIM just disconnected.
No tweaks, clean install.
I reinstalled whole phone to stock (Stock ROM locked my phone using killswitch, so I reinstalled it using BoardDiag)
Flashed CleanRom again, SIM works for few minutes then disc.
Also tried cm11,13 and few modems.
On cm11 SIM working whole night and at morning after some use disconnected.
SIM works normally in another phone.
I record log, which happens every time i turn airplane mode off, reboot or similar "SIM connect try"
Maybe my SIM reader just stopping work, but why after x minutes?
Uploading logs from phone failing, here is G Drive link:
log1
log2
Sorry for my bad English, I'm still learning.

Hi,
Lot of people are having this issue in the last couple of months.
It's not the SIM reader, it appears to be something related to heat in the transmitters area.

Mi Max Helium strange Sim-Card Behaviour

I own a Mi Max Helium and from the first day I use it with open bootloader and Custom Roms.
After 4 Weeks of using the strange things began:
- I lost network sometimes, but most of the times it was back in seconds. (once or twice a day)
- then randomly the MiMax said there is no sim card installed. Ok reboot phone and everything was okay. (once or twice a day)
- then it happened every hour
- and then sometimes after some hours or some minutes - not replicatable
- as a last step rebooting the phone doesn´t help. I have to kick out the Sim, wait some seconds and put it in again
Ok I thought it was a fault with the custom roms.
Made a real big factory reset with mi flash tool and cleaned the whole phone like a new device after the delivery.
After the first reboot it wasn´t able to find any simcard (IMEI und EFS was okay), so I thought phone or SimCard has a defect.
Took a simcard from my girlfriend - everything was working fine. Took my simcard in the MiMax and curiously everything was working fine
Flashed Xenon HD Custom Rom and everything worked well the last 4 Weeks and now the whole Sh*t begins again in the same way like described above.
Wtf is that behaviour? Can anybody report similar things?
Using SIM-Slot 1 or SIM-Slot 2 makes no difference. Its not logical or reproducible for me

T-Mobile? There has been reports not only fo Mi Max but One Plus X and some other Chinese brands killing particular tipes of T-Mobile sim cards by constantly trying to write on them. Sounds exactly what you are describing.
Solution is call T-Mobile, they know the issue and should replace sim card with the right tipe.

Interesting. No I´m using a german multiple provider called 1&1 and they use Vodafone D2 Network here.
They also use Telefonica (ePlus & O2), but the reason for that behaviour could be the same. I will call my provider and hope the know similar cases.
Thanks for the advice so far :good:

Well I share you problem I am.from Chile and this started to happen after updating to official ROM 8.2.3.0
I tried for months to find a fix but in the end I've noticed in my country all operators started using 4g band 28 (700mhz aggregation) band is not compatible with my Max prime (helium)
This doesn't explain why the card is lost until rebooting the Phone though.
A good thing is to set auto turn off in security app at 7:00am then enable auto turn on at 7:10 am this way your phone will work in the morning and not lose any important phone calls.
Check out this thread
Do you have any similar symptoms? Can you search for networks manually? I can't
