Hi,
I have an unbranded LG Optimus 2X with Vodafone D2 in Germany!
Since I got an custom rom on the mobile I get no data connection when I'm in 3G and sometimes also in HSDPA!
I tried Fearkills, BlazingDragon and even flashed back to stock! but I still have the problem!
By stock I used this: http://forum.xda-developers.com/showthread.php?t=1035041 (the czech,germany,... version)
While getting custom rom I also flashed new baseband version so I think it's because of that! Before I got 0218 or sth like this...
Now I tried to flash the older baseband version 0315 in stock, but still the problem!!!!
Don't know what to do else, do you have similiar problem or any idea which could help?
Desperatly
You set the correct APN?
Yes, I think so, got the standard settings:
APN: web.vodafone.de
MCC:262
MNC:02
Authentication-typ: none
APN-Typ: default
Rest not set!
and the event.vodafone.de but this is only for mms, right?
Hmm, the APN is correct. Could it be related to your SIM?
Hmm, well it is the SIM of my old mobile (HTC Magic) so its 1 and a half year old...
Can I check it when I put it into another mobile and there the 3G thing works??

Try to delete all APN and then write them back again.

Thanks so far for your suggestions!
Tried to put another sim-card into the mobile phone, but same problem there!
But it was a very old card, will test tomorrow with a newer card...
I cannot delete the apns, but I just did a reset, and it seems to help!
I got a website loaded by 3G! but it also died once so far ( then the arrows get black and no conncetion again)...
Some more suggestions what it could be? at the moment I'm in stock and even updated the baseband by LG's update software( V10b to V10c, 0315 to 0405) but still get many failures that I dont have connection, although I have!
Changing SIM-Cards didn't help, the sim put into my mobile had the same problems...
I even flashed stock with nvflash, but I can't find a version where the baseband is included, someone of you knows where to get one?
use APN Backup & Restore
If you backup, delete and then restore all APNs you can delete them manually (they are not greyed out anymore)
You can also delete them all and define the one you need manually.
Could it be that there is a general problem with VF Germany?
I also have a VF Sim and my Optimus often loses the network connection.
It only connects again when I power it off and on again. Otherwise I have no phone or data connection. Very annoying.
I have a new hint!
when im calling *#*#4636#*#* and get to mobile info(sry have different language) and then deactivate network and then want to change the network mode from for example gsm only to doesnt matter what there stands unknown and cant change it anymore! This doesnt work as supposed to be right?
After that i have no connection at all cannot connect anymore and must restart to have anything again!
I hope this helps for some pros to help me fixing it...

When my comnection dies the symbol for "at home "dissappears...
Is there perhaps a logfile for that or a possibility to look whats going wrong with adb?
Anyone of the othersbwho have the problem, could you fix it?

Hello, I bought of a friend a Samsung galaxy s and he said it needs only unlocking,so i "think" i unlocked it successfully.Was putting a O2 Simcard in and in applications i was having then the o2 SIM Toolkit.
But when i tried to make an phonecall, he tells me "Mobile Network not available",so i went to settings and wireless and network and tried to choose an network operator but he tells me then " Unable to connect to this network at this time.Please try again later."
What can I do?
Did you check the APNs?
Please first check if your IMEI is intact. If it is, flash a different MODEM and see if it works. If it's not, flash a fresh ROM using ODIN and that should hopefully restore your efs.
At first thanks for the reply, but now what is a APN? And how do i know if my IMEI is intact?
Sry,am a newbie
For you IMEI you should check your original SGS Box's sticker. There should be you IMEI number printed on. If you dial *#06# you should be able to read your IMEI. --> Look if it is the same as on your box
for apn settings. Apn is your connection settings, how your phone connects with the providers network. you have to check your mobile network settings if these are correct.
So, the IMEI nr is different then on the sticker,and the apn wasnt ticked,so I ticked the O2 and tried but still no mobile network.
Then i need to flash if I'm right?
I was already looking a bit around here about roms etc. But there are quite a few out there,so when you say to flash a fresh rom,which actually do I need to use?
Thank you
Hi again,
because the imei wasn't the same, I flashed it with a new rom (actually two different ones)
But still after both flashes I still don't got my old imei and still no mobile network available. After the one flash with I9000XXJPU he didn't said anymore no mobile network available,instead he said no data network available.
It would be nice if somebody would have some advice or help.
Thanks
hey! don't panic, i have had the the same problem
just download darky's resurrection edition in the development section and flash it. it should bring you back to froyo 2.2.1 and should also restore your imei properly. after this procedure you are free to flash any rom you want

Flash back to 2.2.1
Check imei
Continue on..
Also the problem you had when flashed JPU sounds like you didnt have your APNs correct..thats why the "no data network available"

No Network
Hi!
I have the same problem.
Network is fine (i switched the SIM-Card into different phones), but my SGS GT I-9000 does not connect / find to any network.
I am running Darky`s ROM 4.0.4 v11.0 Black Edition with 3.0.17-Semaphore_ICS_1.2.5s.
Also, the phone says on screen the name of my network provider (COSMOTE), but no signal.
What now?
Dear Experts
I was having some weird issues with my XT862 flashed with XT883 china telecom ROM. So I thought about a factory reset. After reset my phone was up & asking for network activation, I managed to skip it but it is not accepting my CDMA-OMH sim card & says INVALID UIM.
If i go to network selection at first click it crashes & then reopen with 3 option of 2g/ 3g/ Automatic. Earlier I used to get 3 options as GSM Only/ CDMA Only/ Global (GSM/CDMA). Now when I insert CDMA Sim i get a green + sign instead of signal bar & error : INVALID UIM & if I insert a GSM sim I get a sim error icon & no signal bar icon & error : NO SERVICE (NO UIM CARD)
As i checked up *#*#2468#*#* doesn't work after OTA update to 57.1.60.
On dialing *#*#4636#*#* I get all the options & I select CDMA Only (PRL) but nothing happens.
Luckily I had safe strap installed & it was working even after factory reset & I am able to restore my backup.
I even tried copying build,prop & ril files from working backup to system & etc after factory reset, but nothing changed.
Please help

You need the build.prop from the AT&T/T-Mobile thread.

Still on XT883. Downloaded XT862 Verizon ROM one click flash (RSD Lite) but not Flashed till now.
Confused that shall I try MVP3 method or this one. I am afraid of loosing CDMA-OMH else If I had GSM I would have flashed.
But I am going to do it any way, just waiting for another CDMA phone in case after flash I am not able to configure CDMA OMH.
Which ROM you are using?
I'm running the 883 radio and build.prop and I don't think it will let you run CDMA and GSM at the same time.

I'm running that Rom on my xt862 and was under the impression that after flashing the build.prop and radio.img files that you can no longer use the cdma and global capabilities of the device.

Correct. My phone in theory should use a Verizon signal but when I switch over it doesn't find anything.

If I am not wrong , I have seen post on XDA about how to use Droid 3 on T Mobile & ATT after sim unlock & also switch back to Verizon if required. It may not work together but it can work that way. Please correct me.
So in theroy if I flash XT862 and I have to move back to XT883, should there be any problem?
When XT883 ROM works on GSM/CDMA together why XT862 can't be modified for that. (May be a silly question)
I didn't think it was. I dunno. I always have had to flash the 862 radio.

You may be able to make it work for you, I flashed my D3 strictly for use on AT&T because I dislike Verizon but they seem to have the best phones. Let me look around on google for you and if I find anything I'll send you a pm.

http://rootzwiki.com/topic/28888-cd...rom3d-v42beatstweaksxloudbassmod/page__st__70 this might help you with switching back to cdma and using it. I'm almost positive though that once you flash the radio and build files, that you won't be able to use the cdma side of the phone anymore.....unless you use the unbrick method thread on here and take everything back to stock.

You can flash the radio file from the 890 spb and get a regular build.prop easy.

You probably just had to flash a radio to it using fastboot.

radio ????
Radio aka baseband aka modem, without it your phone will not get signal.
Just check for it in the Settings -> About tablet, under Baseband version. If it said unknown, then none is installed. If its there and you still don't get and signal, maybe something is wrong with the rom you are using. In anycase try following the guide to factory reset your device using fastboot.
Can somebody help me with this 4g problem?
This is what i did:
1.flashed custom ROM (worked like a charm,i did nandroid backup)
2.flashed other custom ROM (didnt like it so I restored the first one from nandroid)
3.everything went well except no imei and no baseband
4.reverted back to stock rom with odin
5.and here is the problem,no 4g signal at all. 3g/2g works fine.
If I post my build.prop can somebody tell me whats wrong?
I have tried to put my sim card in other phone and it works but not in my phone.
Did you enable 4G in Settings?
Sent from my GT-I9305 using XDA Free mobile app
Yes, I did...network mode is set to LTE
Is there a test that I can use to test is it a software or hardware issue?
Maybe an issue of Stock rom you flashed using odin.. Which one exactly have yoi flashed? What modem you have now? And finally, is your S3 i9305 or some i9305T variant?
Check this out:
Typ *#*#4636#*#* and goto Netinformation, then you will find a special-setup for the 2G 3G & 4G.
Sorry about my english. Cause i am german.

Thanks for your replies,I flashed stock german 4.4.4 from sammobile.It worked very good about 2 months.
I think that modem is xxufoa1 and version of phone is i9305 lte international.
If somebody could help me with this issue,I would appreciate that.But no hurries,I got new playmate S6 edge...
try doing a complete wipe of data and cache, then flash stock rom again to see if problem persists
I have tried many times but no help...
Hey, try flashing the parambin.zip file (look for it on google related to s3 lte, you'll find it easily). Another thing to try is just wait with the phone turned on with a valid SIM. I found out that sometimes it delayed a lot to get signal, specially when changing SIM carriers on another country. After a while waiting it finally succeeded (probably unrelated but I also saw on the catlog entries about upgrading the sahara file of the qualcomm chip -the modem-).
