[Q] Mobile network not available - LG Optimus 2x

Hello,
Since recently I can't make any calls (or sms or 3g etc) with my o2x. I installed gb through smartflash and every time I try to call someone I get the message "Mobile network not available". I tried deleting my IMEI (Erase cal data in smartflash) and setting it back, and my imei is like it should be. But i still can't make/receive calls :'(
In About phone -> Status it says at mobile network type: UNKNOWN:0
I also tried other roms (on new bootloader) and stock gingerbread and changing #ro.telephony.default_network=0 to ro.telephony.default_network=0 (aka enabling it, I found this setting today and thought it may help me, but that isn't true)
I also tried rebooting my phone and turning on/off aeroplane mode, but since the problem is on all the roms, I gave u trying that.
I found that other phones also had this problem, but using their fixes also didn't work...
I hope you can help me

you lost your imei, search forum for imei restore procedure. its not as difficult as it sounds. a lot of people - including me - already had this problem

Maybe it's a base band problem. I lost my IMEI but i can still make phone calls.

I already did that. I tried to reset my IMEI and setting it back to what it should be because someone said that that may fix the problem.

I tried 30a and 30b and stock gb one, so I don't think thats the problem.

Did you check the SIM Slot?!
First, try to go back stock ICS.
In my case, i was have same problem like you.
but i was solve the problem after go to stock ICS.
Please check!
1. SIM Slot
2. /system/lib/lge-rill.so
3. IMEI Number Changed
etc...

Maybe a damaged Sim card ??

Sim card is okay (I tried another one, didn't work either), my ril however didn't exists, so I downloaded ics-newbl-ger from goo.im (for the p990) and that didn't work. Can you suggest another ril?
My IMEI is ok, i'll try to go to stock ics/gb but can't find any links? Can you give me one?

Maybe a problem with baseband and RIL. I don't think that the V30 baseband will work with Stock GB ROM. Try a GB baseband and install a compatible RIL, eg. with the GetRIL app from sibbor.

[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??

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] Unable to make calls. How to solve?

Hi,
I have a strange problem. I am unable to make calls from my P990. If i try to make calls with UMTS active my phone does nothing. It is unable to call or get called from anybody. SMS do NOT work most of the time.
In GSM mode i can send and receive SMS messages and receive calls. But i can not make a call. It rings but when the called person answers the call my phone just ends it.
I think this problem can not be ROM based, because i switched from multiple CM10 nightlys to the leaked ICS by tonyp and harsh a few days ago and the problem is still there. While i changed the rom i did every wipe i could find, cache, davlic cache, internal sd and factory reset and fixed permissions as well.
Before switching to the leaked ICS rom i tried different (at least five) basebands to overcome the in call audio bug (loud strange noise on the called persons side) which worked for a few days, but then started to develop this problem. With the leaked ICS rom i tried both the P990_V28E_00_CP.fls and P990_V28G_00_CP.fls from tonyp's download site.
Can anyone think of a way to solve this really annoying problem?
If you need more informaion, like log files, build numbers, etc. please let me know what exactly and i will try to provide them to you.
Thank you for your help.

I tried this today, same problem here.
Something i forgot to mention is that when i try to call somebody and it does not connect i have to force quit the connection to the mobile network to end the call attempt from the phone. So i have to either switch in to airplane mode, deactivate the mobile network or switch from gsm to umts or the other way around.
If i do not do this the phone will try to place the call as long as possible with no result.
Do you think i should try and go to stock froyo and see if the problem persists?
u can try to nvflash the stock rom.it'll be clean then.
i-ve had the similar problem with leak ics rom.
my sim was over 10 years old and after changing the card problem was solved.
my telecom gaved me newer one with the same number.

I flashed the stock (2.3.4) rom (kdz version) with AIO-P990-ToolKit_v1.1-fixed which uses the official LG flash tool after making sure to have the gingerbread partition layout.
So now i have an old system V20Q_00.kdz with Baseband version 1035.21_20110725 but i am still unable to make any calls.
I will try to match baseband and ril next, but if this does not work i have no idea what else to try.
Anyone else?
Thanks.
OK, didn't work either.
Next try is the rom and the baseband from here http://forum.xda-developers.com/showthread.php?t=1504280.
ROM: Gueste2X "GoodBye" v2.0R
Baseband: v20l, 1035.21_20110725
Sms work without any problems, but the main problem remains. Calls, last about 3 seconds. Regardless wether the called person answers the call or not.
Calls to me are working perfect. Checked my APN settings and they are find to.
Is there any logfile i should provide to help track this problem down?
Any hints, suggestions ?
Thank you.

Well now it becomes really strange.
I tried a different sim card a few days ago. Same problem. Unable to call anybody. Today i tried it with yet another sim card. Calls worked perfect.
The only difference between the sim cards is the following. My original sim card is from bob (virtual provider from A1) and the first sim which did not work is from A1. So technically they are from the same provider. The one which worked is from a different provider (telering).
What adds to my confusion is the fact, that my sim card works perfectly in another P990 without any problem.
So somehow the combination of my P990 and sim cards from A1 and its virtual provider bob do not work. They send me a new sim card during the next week. If it works i'm happy and can finally make calls again.
If not i will change provider. :crying:

Wow. This worked. Thank you so much.

No Sim Detected LG Optimus 2x :(

Hi
My phone suddenly stopped detecting all sim cards ( I have tried various working sims ).
It is running CM 7.2 and has been running cm 7.2 for a few months with no problems.
Today I took out the sim and put it back in to reboot, all was fine. I went to shower, came back and the sim suddenly stopped being detected.
I have tried to google but it seems most problems are to do with flashing a new rom and having the sim not work, my case is that the rom has been the same for a few months.
I have tried to flash different roms and I still have the same problem. I have a gut feeling it is the hardware that reads the sim that is faulty.
I have read something about a baseband, I dont know what that is but if it helps, when i go to the settings and click on 'about phone'
It says there is a baseband and it is version something. There are no question marks or anything like that.
I appreciate the help and would love some more troubleshooting suggestions.
The worst case scenario is unrooting it, flashing stock rom and send it back to warranty. I actually don't know how to do that so if anyone has a guide lying around please link me on that.
I have similar problem with new boot loader.
Download getril app from play store and see if your baseband is OK. If not, download and flash matching baseband from development thread. You will loose all personal data and your apps after flashing. Then download new ril with getril and reboot. Good luck...
This method was no helpful for me. Maybe you will have better luck.

Thanks for the reply,
When I first opened getril, it said RIL not found, I did not have one. I downloaded one and then it said RIL does not match. I then redid it on another firmware and it now says RIL and Baseband matches. Is this enough? The only weird thing is the baseband has canada and europe in it. I am from Australia. How do i tell which baseband/ril I need?

First you flash BB, then download RIL with GetRil. Read completely through BB sticky topic in development section. All answers are there.

You can flash as much as you want, none of that will help. Had same issue once, flashed almost everything there was through SmartFlash, NVflash and all of that. This is what you need to do:
First, remove the battery from your phone. Write down the IMEI. Now boot up your phone, write *#06# and see if the IMEI that pops up is the same as the one you saw behind the battery. If not, let us know and I'll hand you the solution, but first check if the IMEI matches.

I checked the IMEI and it matches.
I have some extra information if it helps, when I choose a random RIL from getril, the battery might become a ? mark and the sim card not detected error doesnt show anymore, however when I put it back to the original RIL, my battery bar starts showing the 'power left' and also the sim not detecting error shows again.

I get the SIM Toolkit Incompatible Handset error and then whether I press OK or Cancel, shortly after I lose mobile network access. I've been trying all manner of different things, Smart Flashing, NVflashing, changing basebands, Rils, you name it.
I'm currently on the V30B root ROM http://forum.xda-developers.com/showthread.php?t=2064793 and the Ril matches the baseband from that ROM, but that hasn't helped either. So I went and check the in phone and behind battery IMEI and they are different! I'd love to hear what your solution to this is!

IMEI Solution
If IMEI does NOT match, you will need to do this:
Check if you can get in a menu by typing 1809#*990#. If you can't, you will need to use a GB ROM (I remember I used Homero's GB NVFlash as I was on ICS bootloader and couldn't get access to it on ICS). Follow these steps if you are sure you can get into the menu:
1) Connect your phone by USB.
2) Enter 1809#*990# in dialer.
3) Select Port Setting -> Select CP USB
4) Install a program called Hyperterminal on your PC and open it. In COM settings select same port as in device manager -> LGE Mobile USB Seial Port (should be 115200)
5) Type at%imei and it should respond by saying OK
6) Now type at%imei and it should now display your current IMEI number.
7) Type at%imei=XXXXXXXXXXXXXXX where X is your original IMEI number.
8) Reset phone.
You might have to reboot your phone after step 3. But see if it works without.
I have been thinking that this is a hardware issue, I have not changed a single setting/rom/baseband at all, the sim just wasnt detecting when I came back to my phone. The rom and settings were the same for a number of months.
I am now going to give it in to warranty, however it only has 1 month left. I have tried to install the stock firmware but with no luck..
I found a rom to flash for my region, it is a zip file but when I try flash it with Clockworkmod, it says installation aborted....
Shouldnt I be able to flash the roms with CWM? The file is a zip file just like the CM7.2 rom I flashed. Do I need nvflash instead? I found the rom here :
http://forum.xda-developers.com/showthread.php?t=1852112 (the download links were removed so I googled the exact same rom)
I was also told that if I just use the LG update tool, it sohuld automatically update the phone to stock firmware AND unroot it, only that the update tool gives me an error. Whats the best approach guys?? I need to get this fixed before my warranty goes.

Your imei should not show in settings, it should show in the back of your battery and when you dial : *#06# into the phone (where you dial numbers for calls).
Cant help you with baseband.
OP here, I am trying to unroot my phone and put stock firmware to get warranty to fix the simcard reader ( i believe it is a hardware issue ).
If I use nvflash and flash any stock firmware I can find on the internet, will that be OK? I have a feeling each region of optimus 2x has slight differences in firmware, eg swedish stock roms and australian stock roms may differ in the default applications etc.
Will it be ok to just install any kind of stock rom for my warranty? Help would be appreciated my warranty is running out in less than a month now.
I also tried to flash stock firmware with CMW, it didnt work. I am about to try NVflash, so I went into greater detail in page 1 but no one replied yet. If you guys know please help. I am more familiar with CMW than NVflash. I have not used NVflash yet.

I managed to get an old CM7 install back on the p990,but the above is still not working for me :/
After I finish typing in 1809#*990# in dialer, nothing happens. If I press the green phone handset icon to dial that number it comes up with an error message of "Mobile network not available".
Any further advice? Thanks.
Okay, I failed at reading comprehension – it has to be an LG Gingerbread ROM for this code to work, NOT a CM-based one!
Trying one from somewhere-I-cannot-link-to-yet
Success! Once I was back on the original stock LG Gingerbread ROM, I could reset the IMEI and make/receive calls again using this method. Thank you very much!
Now all flashed back onto a nice "working" nightly CM10.1 and a very happy little device.
Many thanks all.
Hi,
Anyone have a working link to "progmaq-default-cm-10-20121105 ". My Optimus 2x has been bricked as well, and can't find any other version of this on Google unfortunately
Appreciate all help.

[Q] Full signal but not able to make calls HELP

Well i got a problem.
My LG optimus 2x doesn't want to make when it has full signal. And that's ONLY when it has full signal. As soon as I start calling it says call ended. Other people can't call me either. Everything else works fine from internet to messaging (receiving and sending). I have tried numerous basebands (0725 v20q, 0725 v10d, 0218 v10b) and the one I'm on now which is V30A.
I'm currently running stock LG 4.04.
I have tried the phone with a different sim and it still didn't make calls.
Switching to 2G or turning airplane mode on/off doesn't help neither doe turning on wcdma or gsm only signal.
I was installing the basebands with LG P990 All in one ToolKit.
ANY HELP GUYS.
Thanks
Switch to a custom rom ^^
Already tried it doesn't help. I will flash Avatar ROM again but first i want to fix this
Nobody knows? I don't think it hardware since the phone can make calls but only when its not on full signal.
Could it be IMEI problem?
Have you tried a different sim card?
Dial *#06# and see if your imei appears
IMEI problem what do you mean by that?
The IMEI does come up.
And yes i have tried different sim cards with the same result.
Does the displayed imei match with the one printed on the sticker under the battery?
Yep they match.
You have the problem which I had when I was using su660 basebands. As I see you were trying p990 basebands maybe you cold try a su660 baseband. Here's the su660 baseband with it's ril Flash the bb with smartflash, then if you are on stock or stock based rom copy the ril file to /system/lib and set the ril permisson to rw-r--r--
Will try. I'll post back if it works or not.

Looks like i can't past it inside /system/lib because it keeps saying that the system is read only.
Should i Flash Avatar ROM so I have full control?

Of course, flash avatar rom or any other which grant you root acces or just root your stock rom, but if you still have that problem without changing ril it just will be a worthless effort.
If you still have that problem try this. Maybe it wil help. I know it is for fixing some kind of wifi-mobileinternet transation thing, but you can give it a try, you will lose nothing. Read carefully the post. I think there is nothing to worry about. I perfomed erase CAL numerous times without no problem. I would recommend putty instead of Hyper Terminal.

Erase CAL deletes the calibration data in the radio. By radio I mean that part of the phone which is responsible for catch signal/network. When you perform Erase CAL you lose your IMEI, but you can restore, that forum link I sent describe it how to restore your IMEI after erase CAL.
Answer to your second question: You can only use erase CAL when you flash baseband, and you need stock rom to restore your IMEI.
Why you need stock rom? You need stock rom because it has Hidden menu which is missing from custom roms. Hidden menu is essential to restore your IMEI.
You can find your IMEI on your phone's box or on the sticker under your battery, or type *#06# in the dialer and it will show your IMEI.
I suffered from this problem when I installed Kaspersky Anti-Virus. It automatically enabled its filter and I couldn't make or receive calls, depsite the signal strength or 2g/3g.I disabled the filter and it worked after that. Also, unrelated, but I also suffered from a problem where after a few calls/texts/switching data on/off, I would lose connectivity until the next reboot. I solved it by disabling automatic time and automatically setting the time using the clocksync application from the play store. Hope I helped, good luck.

Weird problem with modems: "Unknown" baseband, IMEI, etc.

Hi!
Resume:
My note has some weird problem with the modems. I'm getting "Unknown" baseband, modem verison, phone number, IMEI etc. with all the modems I tried except one, which shows the correct IMEI and modem version but still not working(I can even see the mobile networks with that one, but I it doesn't connect and gives me "Refresing SIM data" messages).

I always have been using custom roms(only TW) and updating my note to the latest version and I never had a problem.
One day, some months after the last rom update, started to lose the phone network conection and I was getting pop-ups with "Refreshing SIM data"(was very annoying because that was turning on the phone screen every few minutes). Sometimes I had phone network and sometimes I hadn't. The disconnections became more frequently. The phone also started to eat up the free space for apps, so I had to remove several apps to install or update even a small one.
So I decided to change to a different ROM to see if that fixes both problems, but I got the actual problem.
I was in AllianceRom v3 JB when that happened.
I flashed this AryaMod 5.5 JB following their instructions and I got this weird problem. In the "About phone" says that the Baseband version, IMEI, IMEI SV, Network and My phone number are "Unknown". I can't even search for mobile networks because it says "Insert SIM card" when I try to open the Mobile networks menu. Tehre are no signal bars, only a "denied" icon on the status bar.
I tested all JB modems and some from ICS from the "all modems" thread, but I was getting the same "Unknown" things in each one, except the XXLSO, where the Baseband version, IMEI and IMEI SV were okey. I could also find mobile networks with this modem, and the "Refreshing SIM data" thing returned, but it was not possible to connect to a network. With this one, there aresignal bars, but they are empty.
I flashed the AllianceRom and even the old ICS rom I had before, but the problem persisted, even with the modems they came with.
Now I'm on the latest Samsung rom(LT4), unmodified and flashed with odin and the problem persist.
I found this old thread. His initial problem is very similar to mine, but they don't know what caused it nor how to fix it.
I have also found something about corruped IMEIs that you can fix doing something with the ADB and restoring EFS folder, but I think that is not my case because I can see my original IMEI with the XXLSO modem (and I my EFS folder looks OK, anyway I have no backup of that).
I don't expect to get a step-by-step tutorial about how to fix this, but I hope somebody can put me in the right direction. I will post the solution if I find one!
What are the first 4 digits of your imei

Thanks for reading, the four first digits are 3595.
Maybe this is a stupid question, but have you tried re-seating your Sim card, or even a different Sim?
Sent from my Nexus 5 using Tapatalk
I tried both. Also I have been using the SIM with another phone for weeks and works fine. Tried to take out the battery and wait few minutes and other "stupid" things like re-flash a ROM, re-wipe all, etc..
Maybe it's the programed obsolescence, you can use the Note as PDA but if you want a phone, go and buy another...
@ThaiDai or @nokiamodeln91 I believe knows of a way to fix this if its an EFS issue...but you don't have a developer imei
Did you have an old efs backup from when u first rooted your phone?

If it was a corrupted IMEI issue then it should not come back when the xxlso modem is flashed.. And also not sure why it goes to unknown when any other modem is used.. Could there be any physical damage to the sim tray? Dropped the phone?
I have no backup of efs... I had one "nandroid" but deleted it after everything was okey...
I could delete the efs folder, so this unknown problem will turn a known one :victory:
I dropped the phone a very few times, maybe in one of those something broke a little and has increased more with the usage? (the disconnections from the network became spontaneus and progressively).
I found this other thread, I could try the same but I can't find the original GB firmware, every link I find is in hotfile.
Check in Samsung-updates.com firmware section. There are 2 GB roms there..
I found a efs backup from may 2012, probably auto-created when first installed ICS.
I flashed the stock GB rom and restored it following this tutorial for my .tar.gz file, but didn't work, so the device may be lost. I only have 3 more backups: boot.img, data.ext4.tar and system.ext4.tar. I guess they are useless to fix this...
Thay you for you support!
