Try another RIL.
Look for the GetRil app in the google play store, it's free.

NO SERVICES with CyanogenMod 7

Guys, I'm just wondering are there anyone of you here having this annoying problem???
Installed Cyanogenmod 7 and it was perfect to use but lately it keep on disconnecting with my carrier..
Please Help~~
What Baseband are you on? I had the same problem, but its solved since I reverted to BB 218.
my BB is 1035.21_20110405
Lately I have this disconnected network issue too. Only by rebooting the network will revive. Was on BB 622. I have since reverted to BB 218 and the network disconnection issue stopped.
Some called that baseband crashing.
Have you flashed the corresponding RIL? If that doesn't work try the 218 BB.
Guys, do u mind to tell me how to flash my BBC to 218?? Newbie here

Do a Nandroid backup first, because it will wipe your device. Then follow this guide using the 218 BB from temaseks MediaFire Folder in his signature, restore your nandroid backup and your done.
I only get this on 405 when running codes like *123# etc.

Flash it from CWM recovery.
Monitor if any more such no network issue (possibly BB crash). Anytime u wish to revert just flash the other file.
I'm not sure if u are using CM ROM though.

nVflash

Hello XDA world!
When I bought my O2X (P990) i had stock 10d BAL Rom inside it.
i had used to flash cwm, ICS, and a lot more Custom ROMs.
So now is time to go back at totally stock ROM.
I wanted to ask how flash 10d BAL Rom to my P990.
i know that smart-flash can't make my phone look like new for LG devs, but Nvflash might be able to.
Can anyone help me with this sitation.
1. How to convert KDZ, or SMART-FLASH files to Nvflash?
2. or anyone can do this and send me a link.
Please tell me how, because here are many nvfalash type roms and some of you know how to do that.
Using Win XP/ Best wishes from Latvia, Peter.
Hello people!? it's really important, please give me any useful information

You can update to V10d after you have done nvflash. I dont think your will be able to update to 2.3 with ota, it will install V10d instead.

Or he can use LG official update tool and update via Computer (after nVflash)... This way he will get 2.3 V20Q, if there isn't any newer version... I think my previous link is for Euro Open ROM.

But [email protected] wrote in his first post that he wanted V10d. If i understand right [email protected] dont want any other version.

Well you are right about his post, but if I understand he just wants to have phone as he bought it, without root or any sign about rooting it... Official update isn't a problem (for warranty for example...). If he really wants V10d, I don't know which version he will get via OTA update. However, nVflash is the way to go, if you want to have the phone as you bought it

OK so only Phantom got my idea about nVflash. The question is HOW TO DO THAT? Stock rom Bal (BALTICS) 10D Froyo.
Lastes version is 20D .kdz for my country.

Are you sure the kernel is different? It's not 2.6.39.4 anymore? I think it's impossible.

You can use lgextractor to convert kdz to smartflash format. Search on google for that.

Actually there is already V30B for smartflash, but you need an account at 4share.com to download it.
Trocopassu posted here a Smartflash version of V30B, no need to use LGExtractor.

Changing basebands

I've been having call problems and I believe it's related to the baseband. How can I change it?. I'm not sure if there was a tutorial about this, but I can't seem to find it.

This pack contains the .fls file of V30B GER, but the baseband is the same in all versions AFAIK, so you all should be able to use it. And also included is the SmartFlashTool.

[Q] Help!! Keep loosing Signal and baseband switches to unknown

Hi
Hopefully someone will be able to help me this. I have just got a Optimus 4x HD and i seem to have a persistent problem of suddenly phone say no sim inserted even when a sim is inserted. Then I restart and sometimes problem is fixed, at other times nothing happens, i check the information under settings and under baseband it says unknown.
The IMEI is also not shown someone please help me!!
I have changed software from ICS to JB then thought it was an issue with JB but problem is with all software :/
I think that your sim has the problem.But before you change sim try to reflash baseband and stock rom via kdz

I would like to know if the problem has been solved and how. I have the same problem with my LGp880. Can't make calls or send sms's. Often I get the message "USIM missing" or other messages like "reorganization of internal processes in progress.try again later".
I have discovered that many other users have the same problem and, weirdly enough, for all of us it started around the same period June 2014.
I have left my phone to LG's technical assitance. Technicians have changed everything possible (new Imei, software update, replacement of pcb-I hope this is the right word in english) but it's still not working. Now they have agreed to substitute it with another model. The same thing happened to many other users of lgp880 that have had the same problem.
The phone has been bought and is used in Italy. Same thing with the other users. So I was wondering if this problem with no apparent solution is located in this specific geographical area. Or if someone outside Italy has found a solution.
Thank you for your reply

Tried with Zaiben - and the same issue. Tried to flash back to ICS but it get stucked at about 18% with flashtool.
It´s either corrupt EFS partition or hardwarerelated (I´ve ordered today a new "simcardholder" that Demetris recommended.
Well, lets keep snooping around at google for a another while. Cheers

AFAIK sim card holder has absolutely nothing to do with your IMEI. Try MoKee or ZAIBEN or flash stock JB with KDZ.

Well, still no luck here. Have not recieved the "simcard-holder" yet - seems like that should be my last resort.
I´m not even able to flash trough LG flashtool - it just fails after certains seconds (about 14-50sec).
Going to flash latest CM11 nightly this evening from clean (everything wiped but CWM-recovery).
For now I´m using my old "one core" Defy.

Still no luck here.... get from Demetris on CM11 official forum that it might work to flash with "newmans flash tool" no luck this far as the tool says that a ebl-file needs to be injected.
