It could be your APN settings. Make sure you have the correct APN settings for your carrier.

Reflashing full rom trough nvflash
Trying now, will check back after...
Did not work for me, however i made a discovery.
There is now two mode's for my network, GSM and WCDMA
and here in europe we usually use GSM/UTMS is there a UTMS radio out there ?
If i set the phone in GSM only it works.
EDIT: It did not acctually worked, just gives me signal strenght, dailout and sms still not work.

I believe UMTS is the common name for WCMDA.
oh, ok.
i still cant figger out why i cant flash my god dam radio.
So i guess ill just have to nvflash it back to stock a cupple of times and try to blame it on the "OTA"

[Q] Full factory reset, now network does not work

Hello,
The short story is that I have a Samsung Galaxy S. I wanted to install some new firmware ( and because Kies bricked my phone a few months ago ) with Odin.
There was a guide somewhere where they did a full factory reset with
*2767*3855#
After I entered the code I could not connect to the network anymore. And cannot make any phone calls or receive them.
I am in Romania, using Vodafone.
I also tried
*#272*[my IMEI]# and selected CNX and after it reboots it asks me if I'm using Prepay or Postpay. I chose Postpay and still nothing.
If I search for networks it finds all of them but I still cannot connect to any.
I entered *#0011# and this is what I get
UMTS : Limited
RRC State : IDLE
WCDMA 2100 Band 1
Reg PLMN 226-1, IsPCS? 0
FREQ DL : 10836
FREQ UL : 9886
CELL_ID : 0xc82811b
LAC : 0x7d16
PSC : 44
RSCP : -96, ECIO : -8

Tell me what I can try right now, or what information you need more from me.
Usually this means that there is something wrong with your APN settings, like they were erased.
Check out your APN settings and make sure they match what your carrier needs. If they aren't right or missing then you will indeed have network issues...

ccrows : the APN settings seem to be fine. As far as I know the APN are for data networking ( internet ) and before if I had no APN set I could still call people.
Reset your apn settings!

Your APN has nothing to do about whether you can call or not, it controls your data. You could have an empty APN and still make calls.
I really think something in your APN is messed up, but its kinda hard to tell without seeing the phone. Your symptoms do point to the APN.
The only other thing it could be is a bad modem flash. If you are sure that your APN is fine try flashing a different compatible modem in Odin again...

I deleted all the APNs and I know that the network worked fine like this.
I will try flashing with a firmware that I know worked before and see what happens.
The wierd thing is that the problem appeared after I entered the factory reset code, not after flashing it.

Hopefully the flash will work since it should take care of the modem issue that I was talking about in my previous post.
Best of luck...

I've tried flashing it with a few firmwares and nothing works, the error is the same.
Do you know what could have been affected by the full factory reset ?
Do you want some more info that could help you identify the problem ?
I went to a mobile service and they said they don't know what to do to it.
They tried to unlock the network and this is not the problem.

[Q]3G network on MiniCM7

Hello,
I couldn't find a thread for this issue, so here it goes:
I was successfully able to install nAa kernel + MiniCM7 2.1.9 and all is working excellent, except for the 3g/2g/edge network... Is there something I should install or configure?
Sorry for my english, I'm from Argentina. My provider is Movistar.
Thanks!

Most unusual coincidence! I'm replying you on the same ROM - using the same device. Except I'm on 3G. The issue may be with your provider. Switch to 3G only and let's know the results.
Thanks for the reply!
I've tried GSM/WCDMA, WCDMA only, GSM only, etc... All the same... It doesn't work.
I've also tried the "only 2G" check... Nothing.
Let's hope somebody can help us...
Let me get this straight: Is it a 3G problem? Or is it an outright connectivity problem. "WCDMA only" works just fine for me. A Dalvik cache wipe sometimes is all you need. But let that be your final resort (after a nandroid backup). Cheers.

Uh, I can use the line for calling or messaging, if that's the question... The problem seems to be with data transfer(?). The navigator keeps saying that there's no connection available, or something like that.
Do you have mobile data enabled?
Do you have the correct APN settings for your provider?
Thanks!!!

Thank you, AlphaEcho.
That was just what I needed. I feel I went from n00b to Supern00b.
I searched apn+movistar+argentina and now I'm happy.

no data after flashing rom

I have tried flashing my friends rom on lg 2x its the Cincinnati bell version. I tried 3 different roms so far and the data don't work anymore. after that I even flashed to stock with nvflash and data still don't work, omg what the hell did I do. I always do full wipe. can you help me
I assume you made sure the mobile data is on (settings-data usage-mobile data).
Did the flashing change the baseband? If so, consult the following excellent thread:

[Q] Failed to enable data connection

My XT862 stock version is Verizon 5.7.906, and everything works well except wifi(it always show an error and can not lunch, even if I reset to factory settings or flash sbf)
And in SafeStrap 3.05, I installed CM10.1-2013-03-23 version in slot 1. the wifi works well but I can not turn on data connection. I am using a WCDMA network. In *#*#4636#*#*, I can find it works on UMTS mode, but no data connection. I tried to enable data connection via correct the checkbox in setting and in the *#*#4636#*#* menu, but both failed.
How can I deal with it?
Sounds like you forgot the GSM mods to the build.prop. Are you using the 862 or 883 radio?

I am using XT862 radio, N_03.18.32P.
This problem appeared about a week ago, when I am using the 2013-03-17 build, and it continued when I upgrade to 2013-03-23 build.
There's a line that you could try uncommenting in the build.prop like ro.ril = 284000 or something and one below it. Or you might have to add that. See if that helps. (Or you could try an 883 build.prop).

I tried what you say on stock rom radio and the baseband become unknown. And I tried to change my baseband to n_34.18.16s, the system can find baseband and call or send SMS, but still no data connection.
