Emergency Calls Only!

Hi guys
This is the first time ever I am trying an android phone out coming from an iPhone 4.
So basically I got my nexus s yesterday it said it was on vodafone but I understand the nexus s is fully unlocked. Anyway yesterday I put in my o2 sim and it worked out the box making calls etc. I rooted it and everything was fine. This morning I used the gps for a trip to work it worked perfectly. I could connect to the 3G network etc.
When I came home in the evening I tried to make a call and it said emergency calls only but it doesn't let me make any calls! I have hard reset it. Tried different roms. Erased cache etc etc. Still nothing. I called o2 support and they said from their end my sim is fine and no problem with it there is no lock etc.
If I go into the diagnostic tool thing *#*#4636#*#* it says the following
Signal strength -107 dbm 7asu
Gsm service: emergency calls only
Gsm disconnects: state:dcinactivestate disconnected with last try at 12:59am fail because no error
I have no clue what's wrong please help!

nevermind, missed that you had done that

try another SIM card
i had a similar issue, and the problem was the SIM card

Some one please solve this damn issue......it is more spread in India.......tried all baseband updates but still......driving me crazy

Same problem here.

Hope may fix!..under testing..Emergency calls only!!
I was so much annoyed with this so called network drop issue 'emergency calls only' which is appearing on my moblie every now and then and while on important calls..suddenly cutdown due to network loss.
im not a techy geek to go into kernels and rewrite some of the scripts ..etc..
so i may sound silly..but pls try it out..its working for me for last 2 days without drop..may be bcoz of wat i did or may be simply dont knw still testing..so i thought to share this across and see wat others experience..
the actual thing wat i did find is that there is some .005 mm gap over the sim in sim slot so i felt it may be a cause of some not contact of sim with the slot..in some micro levels..
so i introduced a paper above the sim while inserting sim in slot then it becom tight enough to stay its in contact all times..
its simple.. but u people hv to say weather its bcoz of this it works ..
Thanks Ram..

Same issue!
hey guys,
I am facing a similar issue.
I picked up my Nexus S (unlocked) running on 4.03 from UK, but using it now in India.
Baseband version - I9023XXKI1
Kernel version - 3.0.8-ga178ab4
Build number - soju-userdebug 4.0.3 IML69C 235871 test-keys
When I use any SIM here (Airtel/Vodafone), it is getting into Emergency mode. But strangely the GPRS service works. I am able to browse, stream, email etc. I dont understand how GPRS services are working when GSM isnt?
I am unable to use my new phone! Can anyone please shed some light here...

My nexus does this also, I've only found trying different radios to help but not eliminate the problem. Also when searching for networks, manually selecting your carrier instead of having it on automatic also helped.

I had this problem the other day. I was on emergency calls only, and AT&T said it was due to an antenna outage. Then I told them my wifes phone was working.. ended up at AT&T store, no luck, etc, etc.. To put an abbreviated story of my night of pain.
I tried a ton of different radios, all would not connect to 3g or make phone calls. Until I installed UCKF1 (New Version) from the [RADIO/GUIDE/TWEAK]Radio JK1,JK8,KB1,KB2,KB3,KD1,KF1 & UCKD1,KE1,KF1 with HSPDA Tweak thread. I don't know what that radio file did, but it fixed it. And after that when I flashed other radios which were previously not working, they were working again.
I'm not sure what happened, but while this was going on radios I had used before like KB3 didn't work. Once I had UCKF1 (New Version) installed, I was then able to successfully go to any radio I tried.

[Q] G2X radio broken

I have CM7 installed on my G2X and the radio turns off on its own -- it reports no signal. In order to get the radio working again, the only thing I can do is reboot my phone.
Also, to even get the radio working, I had to install "APNs Backup" from the market.
I am running android 2.3.4 on CM 7.1.0-RC1-G2x
My baseband version is:
M6600A-SCAUNTZ-2.0.9720T 1 [MAR 07 2011 16:00:00] MP:TRULGE_08.09.02R_MDM
Has anyone else had this problem? Can anyone confirm whether I have the p990 baseband instead of the p999 baseband by accident? (as reported here http://forum.xda-developers.com/showthread.php?t=1037098)
Lastly, can anyone help me flash the BIN_LGP999AT-01-V21e-310-260-JUL-15-2011+0 baseband from here:
http://forum.xda-developers.com/showthread.php?t=1037120
Specifically, I am not sure which of the two BIN files to flash, and what the correct nvflash command is (which partition does it go to?)... I can't use smartflash or any windows tools...
I have done a lot of searching and I couldn't find anything to help me out, but a few topics that are relevant are here:

What radio are you talking about?
APN is a known issue for CM7 based roms.
The baseband you have right now is a g2x baseband, though, it was the one when it came out with froyo.
Why you have to partition or repair partition on your phone if it has mo issues with partition?
Sent from my Calculator with Android.

CM7 or any 2.3.4/2.3.5 ROM for the G2x is known to have that issue. They are working on it currently. The APN's Backup App works for me tthough.

FatalityBoyZahy -- do you do anything special with it? It allows me to actually get reception (I can't without it) but my radio will still drop and force a restart. Do you have any special settings on it? When the radio drops the tool no longer has the list of APNs and I have to "restore" to get them back.

I was using the experimental (RC1) ROM so I just flashed the 155 nightly. So far a few of my network issues are solved. I'll update if it's completely solved tomorrow.

I could send you a copy of my APN's if you'd like. You'd just need to put them on the SD Card, and restore them through the app. Shoot me a PM.

I have the same issue. My phone randomly looses connection even in good signal areas. Only way to get back on the network is to toggle flight mode or reboot.

This is a known issue on all Android phones that has persisted throughout all Android versions. Google has worked on the problem and it has gotten better, but they haven't been able to exterminate the bug yet. This phenomena occurs when the 3G signal is weak and the phone switches back and forth from 3G and Edge frequently. Eventually the phone just shuts down the radio due to it switching too much. This is the Android OS commanding the radio to shut off. It is not a hardware issue at all. I have had this issue on every Android phone I have owned. Ironically, the only phone I haven't seen the issue with yet is my G2X running stock GB. The best way to alleviate the issue is to install "Network" from the Market and set the phone to 3G only. If your custom rom has a 3G only option just set it there. There is also an app called "3G only" that accomplishes the same thing. Since you are locking in 3G the phone won't switch frequently and the radio will stay on. You can do the same thing by setting it to 2G only, but who would want to do that.
Network: https://market.android.com/details?id=de.mangelow.network&feature=search_result
3G Only: https://market.android.com/details?id=com.mobnetic.only3G&feature=search_result

I think my issue is more severe than it is for you guys. Fatality - when my radio goes out, nothing but a reboot turns it back on. Not airplane mode, not toggling data on off, not changing apns. In fact, when the radio turns off any menu pertaining to the radio freezes and asks if I'd like to force quit it.
Also, I doubt that this is the long term Android bug. I've owned probably 10 or 15 android devices and I have seldom had to restart the phone because of this. For my g2x, I have to reboot literally 15 times a day.
I had two more leads I am trying.
One was that I have a 5 year old T-Mobile SIM in my g2x and I read somewhere that an old SIM could be a problem. No such luck, the radio has already turned off with a brand new SIM.
My second lead is my baseband. I have a March 7 baseband, but the two basebands online for g2x are March 17 and a later one. So, perhaps I do have the wrong baseband?
Thanks,
Ben

Oops I forgot to respond about jboxers suggestion to limit to 3g. It didn't work, either.
The network app didn't seem to have a 3g only mode, the 3g only app didn't limit my phone to 3g (it was still 4g) it only turned data on/off and also the radio still turned off, so I tried using the phone's 2g only mode and that immediately killed the radio.

3G and 4G on HSPA are inseperable. '3G only' will give you '4G' also.

As another poster already said on TMO 3G and 4G are the same thing. In fact, TMO doesn't have real 4G. HSDPA+ is fast but it is not true 4G. In some countries it is referred to as 3.5G and here in Thailand they are calling it 3.9G.
The network app does work. You scroll down and selected "WCDMA" only. That is 3G/4G. That will lock the radio into 3G and 4G only. The 3G only app will lock it into 3G and 4G only. There is no way to say 4G only, because it is not real 4G. If TMO had LTE that would be a different story.

Ah, that's good to know that 3g=4g on t-mobile. How come sometimes my phone says 4g and sometimes 3g?
Anyway, I wish that was the issue
Does anyone else have any ideas of what it might be?
What baseband version do you guys have on your G2x? Does anyone else have the same baseband version as I do?

HSDPA=3G, HSDPA+=TMO Pseudo 4G. HSDPA+ is an enchanced version of HSDPA with faster speeds but not true 4G. Most devices display an "H" but TMO had it programmed to "4G" to pretend they offer 4G service. Both are versions of WCDMA, which is what GSM 3G is.

I found this thread that has another kernel that supposedly fixes the APN. I haven't had my kernel drop yet, but it's only been 10 minutes Here's a link to the kernel:
http://forum.xda-developers.com/showthread.php?t=1229932
For install instructions, read the instructions in the linked code.google.com issue tracker:
http://code.google.com/p/cyanogenmo...on Model Network Owner Summary Stars Priority
I used:
adb push boot.img /sdcard/ && adb shell dd if=/sdcard/boot.img of=/dev/block/mmcblk0p5 && adb reboot
and everything worked fine (don't forget to clear dalvik cache on reboot).
To run the script he linked to, download ScriptManager from the app store.

It fixed my radio! Though it did kill wifi.

No Signal on G2x

I've had the G2x since it first came out and have always had issues with the signal dropping abruptly. However, since Thrusday, I have lost all signal to the tower and am unable to get it back. I was running EagleBlood's ICS ROM but have since done a full factory reset back to stock and completed an update via the LG Update Tool (I wasn't successful with updating the baseband any other way). Everything appears to be back to factory settings, but I'm not receiving any cell signal still.
Any ideas?
My baseband currently reads: M6600A-SCAUTNZ-2.0.9720T 1 [MAR 2012 10:00:00] MP:TRULGE_08.09.02R_MDM
When I choose Status under the About Phone menu I get the following details:
Network: Unknown
Signal Strength: -93dBm 10 asu (fluxuating slightly)
Mobile Network: GPRS
Service State: Out of service
I am also unable to enable Wifi calling. Basically the only calls/texts I can make are via Google voice on a wireless network.
I'm on the stock 2.3.4 rom currently.

I too upgraded to the new bb, and have been getting random signal drops. IDK if it's Tmo, working on their equipment, or the new base band. I figure I'll give it a week or so, as it hasn't yet interfered with my daily usage (mine drops, then comes back).
My suggestion to you, since your loss seems to be a constant, is to try using kwes 2.3.4. I had some other minor issues w/the LG release, that I don't seem to have with kwes. It's a bit more stable.
http://forum.xda-developers.com/showthread.php?t=1602798
Could just be that you had a bad install. It happens. Give kwes ROM a shot. Maybe that'll take care of it. Good luck!

Thanks for the suggestion. I'll go ahead and give that a shot, but I think in actuality something internally might be messed up.

Have you tried a diffrent sim card?

Random Signal Drops?
I have the some freaking problem, I made the thread above and I've tried a number of fixes and no dice.. Tonight I'm going to try to get a new sim. I've tried a complete reset, Rooting and removing all bloatware, and flashing a custom rom. No dice. Sometimes I drop from 4g to 2g, sometimes I drop all signal. Wifi never drops but I lose all connectivity to mobile data and signal.

Did any of you ever fix this issue? The same exact thing just started happening to me. I had to start using a back up phone to make calls. The only thing that works in wifi and I've verified the APN settings. I even took the sim card and put it another phone, which worked fine. Let me know if you find anything.

If you want to eliminate the phone as being the issue, has anyone suggested you roll-back to the previous Baseband and try using one of the CM7 ROM's that are out there?
Logic being, if the rollback gives you the same issues you previously had, then it's not a function of the baseband causing the issue.

So I have the G2x with simple mobile and just installed the latest eaglesblood and obviously I cant make any calls and texting works with wifi so is this fixed or should i go back to 2.3.4

If your having the same problem I use to download the app “GetRIL" from the play store and check to see if your base and and RIL match if not download the right RIL within the app hope this helps!

Optimus 3D 3G troubles

Hello everyone,
I hope someone can help me because I am going crazy with my Optimus 3D My device constantly loses the 3G connection and so I don't get any notifications about new e-mails and Whatsapp messages. The icons for network strength turn white and even sometimes that happens with the wi-fi icon. I already tried rooting the device and installed a custom rom but I still have this problem. The problem mostly occurs in the office I work in as 3g and network reception is very low here. I see that the device switches between HSDPA, GPRS and 3G quite often and then most of the time loses the internet connection. It also does not reconnect when I walk around and get to an area with better reception. Sometimes switching to Airplane Mode and back helps, but this is not a very handy solution. I am really clueless where the problem could be. I am here in Frankfurt/German so normally there should be no problems with the network (I am on Vodafone). The only thing I could think of is my SIM card, because I had an iPhone 4 before and had to cut the card to the micro SIM size and now use it with an adapter. Could this be a problem? Also the app 3G reconnect did not solve this problem.
Has anybody a clue what might be wrong with my device? I am already thinking about getting a new phone
Cheers,
Andreas

I don't know when it loses the connection, could probably happen when it turns the screen off or switches between network speeds (3G, GPRS, HSDPA). It really is a problem for me that it does not get the connection automatically back. Currently it shows almost full network reception, the "G" icon with both arrows underneath (only the left arrow pointing up turns green from time to time), but it has no internet connection. I sent me a mail to my google account via my office PC haöf an hour ago, but still no message on the phone, that there is new mail

Just try a new simcard... my guess is that it will solve your problem.. could be worth the couple euros ..

I had similar Problems with O2 in Bremen.
That happens if the phone loses the 3g(h+) signal, turning of the data connection, and let that reconnect is enough, no need to turn on airplane mode than.
Try flashing the newest baseband version, and try the prometheus rom + kernel. I still notice that the same problem happens, but it reconnects again after losing it now, and i rarely notice it that way.
Maybe you could tell us your android version, and baseband version.

Hi everyone,
thanks a lot for your answers. I have the newest firmware on it V21E and baseband is L6260_MODEM_SIC_01.1042.00. Problem is that it does not automatically reconnect when it loses the internet connection. I had this problem again the whole day. When I left the office for lunch it did not reconnect, so again I did not get the newest e-mails. Probably I will really try another SIM card with a different network provider. I never had this issue with my iPhone... Thanks a lot for the advices, hopefully something will work. Otherwise I need to get a new phone :/

For me the 3g data service goes as it likes but to reconnect i have to restart the my phone. Tried many roms as well as kernels and finally using acura 3d Max 3.1 with titan kernel solved the problem. It doesn't give up 3g connection but if i switch to edge and back to hsdpa again i have to restart. Barry also lasts and have overclocked to 1.2 ghz

In the Dailer APP dial *#*#4636#*#* Phone info Scroll Down just above the turn off radio button Change from WCDMA Preferred to WCDMA only

Good morning (at least here in Germany it is morning *g*),
got me a new SIM card with a new provider yesterday evening and so far it seems to work fine in the office. I hope it stays like this, then the problem would be solved *phew* Thanks a lot for all your help!

Data not working

Hi all, i have some problems with my sensation: my internet connection works only over wi-fi. When i enable data it doesn't happen anything: in the status bar i don't see the H or the 3G icon and i can't connect. I tried everything but i can't find a solution. I'm using the last build of albinoman's rom and the latest sultan kernel. Anyway i don't think it's kernel or rom related because i went back to stock 3.33 firmware and ruu and mobile connection didn't work either. Can someone help me?

So let me get this straight....your mobile data isn't working on either Albino's CM10.1 ROM or a stock Sense ROM. Is that correct?
Do phone calls work? If they do this isn't a hardware problem because the calls and data use the same hardware. So that's good news.
If all the above is true there are still a couple simple things to try.
First off when you did an RUU was the RUU for Itally or Europe or whatever the geographical region for your phone woudl be? If you RUU'ed back to the North American varient for example and you are in Italy it wouldn't have the correct APN's. So jus tmaking sure of that.
Second, check the APN's (Settings->data (Might have to hit MORE under the data)->mobile netwoks. Access point names). Make sure the APN's are set to whatever they are supposed to be for your carrier. A simple google search should tell you what the APN's are supposed to be.
If that APN is messed up, mobile data won't work.
Third, has this been going on fro a while? Or is this just like a day or two? It's always possible that the problem is with your carrier. It never hurts to call them up and make sure their mobile data network isn't down. It coudld also be a problem with your account. I once fought with my phone for 2 days about the same thing only to find that my carrier had accidentaly removed my data plan from my account. A 2 minute phone call and it was fixed. You can check this yourself by putting your SIM card in any other phone and see if data works on that device.
If none of thsoe work come back with as much detail as possible.

Phone calls work so it's not an hardware issue. Besides when i flashed the 3.33 ruu it was european and the apn is set correctly. I don't know if the problem is that i changed carrier a three days ago. I'll try to see if it's that the culprit

If you changed the carrier at the same time the problem appeared then that is almost certainly the answer. The next question is what to do to fix it.
You could have gotten a bad sim card, or didn't switch to their sim card. Or something relating to the sim card.
Are you sure the carrier has a network that is compatible with the Sensation's mobile data hardware?
