[Q] Phone Won't Detect SIM Card Anymore, No Signal

Hi Team!
So this is the story:
Got my unit
Flashed CM7
Got LG GetRil
Had 226(I think) RIL and xxx bb
Downloaded matching RIL (622 GB leak)
Worked fine
Changed Phone
Put Sim card back into my unit
Now it doesn't detect the SIM card, doesn't ask me for PIN, and just says no signal (duh)
Which means I can't flash the RIL back (if that is the issue)
What do I do?
Kind Regards
¨Neefy

Try a different BB/RIL, you probably have the unknown BB issue if you're using the 'gingerbread' 622.

Yeah that's the one! But how do I get a new one when I have no connection on the phone?
Steps would be appreciated

You do it all off the phone.
Have a read of this: http://android.modaco.com/topic/335494-12-aug-smartflash-stock-baseband-release-103521-20110725/

But don't I just have to change the RIL back without changing the BB? Without whiping my entire phone and such..

Er, I can't remember if that worked or not when I was in the same position, but you can try.
Temasek has a bunch of CWM flashable RIL's in his Mediafire folder: www.mediafire.com/temasek

LgG Optimus 2x No network service HELP!!!!

After custom ROM installation, the phone doesn't connect to Mobile network. Wi Fi is OK. I changed several Firmware (CM 7 etc.) it doesn't work on any.
Moreover I can't install anything through SmartFlash, always the same error:
Trying to communicate with IFX modem, and then - timeout error.
What can I do to fix it?!! (((

KDZ_FW updater also doesn't work.
The same with LG Mobile update

I had the same problem and it's because the APN went missing.

Turn off automatic time and see what happens ....

As for APN and automatic time, will try tomorrow.

Sounds like you got the unknown 622 GB leak, download the 622 Europe BB and flash it, then get LG GetRil and get the 622 RIL, there you go.

Have you payed your bill?

Here you go, p990 -> bb -> 622

Maybe you should try 0725 for me it works better than 0622. Much much better.

the phone show the battery charge ??
Try to flash with smartflash a baseband (try the 622) if smarthflash get error "IFX modem timeout" gives up and ask to 'practical assistance for the warranty. I have tried everything and I had the same problem, but it was useless!

same issue
it was all fine and dandy and since the past week the same ****ing thing happens over and over again. I restore backups, flash basebands, delete cache, dalvik, it keeps on happening. It started after i applied the optimization pack by paul

So, finally I exchanged the phone under warranty.
Nothing helped to fix it. The phone shows baseband, battery charge. Everything looks fine, however it can't connect to network.
Now I have a new phone and don't have desire to flash it again )))

Try another usb port then try to smartflash. Perhaps reinstall your drivers

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!

My problem was no service and IMEI unknown... Never managed to solve it. Reverted to old bootloader and problem solved.
Sent from my LG-P990 using xda app-developers app

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.

Bother. The 1890 etc didn't work on the p990 in android 4.0.4 (nor on my Nexus 4 incidentally), so I guess I'll have to flash down to GB. I'll let you know if I can get it to work, thanks!

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.

hahah after 2 sleeples nights i menage to restore my sim to be recognize ,whit this metod,.. NFlash rulles ))

ATTENTION
The flasher with NVFlash clears all memory, including the Internal SD., so make a backup if u can..

2.- Press and hold Vol- and Vol+ and without releasing the 2 keys connect the USB cable to the PC
3.- Go to the progmaq-default-cm-10-20121105 folder and run flash icon... folow instruction., wait wait wait Enjoy!

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.

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.

same problem

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.

[HELP] Need LG Optimus 4X new baseband(v20c october 2014)

hello all. my phone shows "reorganizing internal processes" whenever i try to make a call. bcoz of this it is unusable as a phone.
also imei is null, baseband is unknown and cellular is in NO SERVICE.
nothing works: tried reboot,
other roms (cm 11, zaiben, mahdi etc..),GetRIL app...
also i tried to flash latest v20c but it always stuck at 10%..
but i can flash anything from cwm(philz touch)
so can anyone please help me with the so said baseband in cwm flashable format or a cwm backup of latest v20c update?
i'll be grateful to anyone who looks into this issue.
thanks in advance.:good::good:

Hi,
I will have your thread moved to your device section.
Good luck!

You will not find ant flashable format for cwm... I think, did you try to flash v20b? Only way to change you baseband is to flash firmware.

i"ll try upload you stock partitions to flash ***when i find some free time***

dude, i cant "FLASH". thats the problem

What about LG Mobile support tool? Connect phone via USB and wait for the tool recognizing it. In the menu you can "reset upgrade errors", the tool downloads latest version for your phone automatically and flashes itself.

Yeah, the 4X is nearly unbrickable. Even when nothing works, LG Mobile support tool can get it back with a stock rom.
I am in Portugal and have the same problem. I read in a different thread that the problem of "reorganizing internal processes" is in fact a crash of the phone/radio process, due to hardware bug that stucks when both voice and data communications are requested at the same time in a 3G network. I'm not sure if even V20C can correct the problem. One solution is to switch to 2G in general, (EDGE data speeds... )and you won't have problems, When needing for a particular download, switch temporarly to 3G.
But if anyone have a 3G stable solution, please share as I am also highly interested!
I tried stock JB. In custom CM roms, for instance 4.4.4 (is what I have now), you won't have a "reorganizing..." message, but you will loose completely mobile communications when the problem occurs, and only a phone reboot will recover it

The problem causes by LG update software when you kdz from 20A to B or C.
about the IMEI the V20C not really solve my problem but it' sustainable.
Bests of luck.

Thanks. i'll try it.

any chance
