[Q] SIM card not detected after upgrade to ICS - LG Optimus 2x

Hello, I have strange problem.
After upgrading to ICS DM X1.1 KoB, it says no service.
GSM network is not available.
Tried flashing matching v28 BB, GetRIL says that I have matching RIL and BB.
Tried flashing OptiICS and TGs ROMs with nvflash method. Same problem: No signal.
Then I reverted to old partition layout, leaving new BB intact. Flashed GB ROM (DM 1.7.1), rebooted, and everything works OK.
GetRIL says that I have unmatching BB (v28g ICS), but GSM network is OK and calls quality is excellent.
Can someone explain to me why I do not have GSM network after upgrade to ICS.
NOTE: This phone had SIM lock, which was unlocked in service shop several months ago, and for six months was running gingerbread ROM until today.

Nobody? Really? Am I posting in wrong section?

[Q] Baseband 0405 D2 Germany

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...

[Q] AT&T and T-Mobile GSM Support in ICS Roms

I am having problems getting GSM service in the ICS roms. I currently have service with AT&T and I am unable to get a signal. I am currently running the Gingerbread MavRom and I have calling service as well at blazing fast 3G service. I did the radio reflashing in FastBoot as well as the build.prop tweaks in Mav Rom and it worked perfectly. When I did the same in ICS, I was faced with problems.
After flashing the radio, the phone booted normally, but when I went to Settings>About phone, The model was still the same and I had no baseband, it was unknown. When I hit phone status, there was no ESN, IMEI, and alot of the other spots also said unknown.
And after copying the modded build.prop file to the system folder and restarting, I could not get past the Boot Animation. I tried this in several ICS roms all with the same result...
Can anybody tell me what I'm doing wrong?
http://forum.xda-developers.com/showthread.php?t=1560519 scroll down and you will find the GSM fix just replace the build prop with this one and you.should be good.

[Q] mobile network not vailable ... help needed !!!

hi,
i upgraded my phone to 4.2 jelly bean slim rom . calling and other things were fine . but from tommorrow i am facing this problem.
in settings=>about phone=>status it's showing my network name and signal strength-64dBm 25 asu . my network is not 3g or 4g .
but my signals are white ( no signals but sim present and detectable) cant call . whenever i try it says "mobile network not available".
after this i checked my sim in other phone . it is working fine.
i put sim from some other network in my sgs but same problem
i flashed the same rom to fix it but no good
i flashed back my ics rom , no good
i did factory reset , but problem is still
i am using this phone for past 2 years and this problem never occoured.
PLEASE HELP ME .
there is some problem with the 4.2 rom or whatever, but you easily fix the calling part by installing another modem.
in my case I can't get the sms to get working, tried 3 modems already.. everything else is super fine.
I had a similar problem where I had no reception! Easy fix though
1. Find online your specific carrier ROM for the phone, (eg. AT&T SGS1 ROM) and flash it, firmware can be what ever (gingerbread, eclair, ICS)
2. Flash your carrier ROM, you may not pass boot screen but that's alright because the carrier ROM still embeds all carrier info.
3 Now re flash your jb ROM and enjoy
Hopefully this helped you out

See how your IMEI is now something like 00499....? The phone's generated a fake IMEI (which allows you to use the telephony functions such as data, SMS etc) because its lost the real one.
1.) Go back to a stock 2.3.6 rom using Odin. Your IMEI should be back to what it was, but check it just to make sure. However if you're able to send texts/make calls/use data again, your IMEI's been restored.
2.) Root it again.
3.) Flash in CM9 first (do the standard wipe data/cache/Dalvik). Let CM9 boot. To upgrade to Jelly Bean from Gingerbread, you need to flash in ICS (CM9) first to preserve the IMEI. Once CM9 has booted (you don't need to stay on it for too long), if you see that you're getting signal, you're all goods. But check your IMEI just in case you want to be sure it worked.
4.) Back into recovery. Wipe combo (data/cache/Dalvik) again just in case. Install Slim Bean from there.
5.) Once it boots, you should be getting signal as usual. Once again though, if you really want to make sure, check your IMEI.

[HELP] no signal no matter what i try

Hello O2X community,
my phone refuses to connect to the cell network. however, it reads my sim card (SpeakOut Wireless). This began last night when i flashed a SU660 baseband and checked "erase cal data". I have since restored to a stock gingerbread rom with a FLS file, but it still didn't connect. I am currently using the official P990hN rom from the LG Updater, with the V30A baseband (i used it before with no problems). It still won't connect.
Any help would be appreciated.
EDIT: Fixed by flashing a P990 BB with "erase CAL data".

Have you tried smart flashing an ICS BB?
then re flash which ever ROM you have been using if you need....
More issues and if need, try starting with AIOT by SPYROSK.....nvflash from scratch.

[Q] 4g problem i9305

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-).
