[Q] Mobile Network State "Disconnected".

After rooting my LG Optimus 2X and installing CM7 as directed via the instructions my phone failed to bot up the new rom correctly, it just froze at the CM7 intro startup video of the blue character. I then tried to implement the recovery of the backup I made before installing the rom through rom manager in the boot recovry screen, but after applying the recovery to the original stock rom that too also froze at the start up screen so I found some instructions to then take out the battery and connect to a PC via USB which I then had to download and reinstall stock firmware which was successful and the phone is fully operational. I can produce and recieve calls/sms/etc but it is unable to connect to to any network to enable me internet access even though it worked an hour before ****ing my phone up in the the "about phone" info it says "Not Roaming" and Mobile Network State "Disconnected". even with full bars. Could this be cause by installing stock firmware from a different country or firmware intended for a locked phone?
I am with 3(three) in Australia on a $49 Plan but bought the phone outright/unlocked from an authorized dealer.
Any help and insight would be great. Cheers.

Maybe you could state how you flashed the original FW and what original FW you flashed ?

And to it the SmartFlash way, I have not had any problems with either NVFlash or smartflash.

Ok thanks for that. I will definatley try it and see how it goes.

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.

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.

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.

ATTENTION
The flasher with NVFlash clears all memory, including the Internal SD., so make a backup if u can..
Download this file: http://bayfiles.com/file/yKZL/eGZ31A/driver.rar The pack includes the APX driver (folder driver)

1.- Remove the battery to the phone.
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

Another issue is it doesn't recognize my sim, there is a cross mark above the signals sign. I am in Pakistan and we have different carrier i tried them all, one of them worked fine and shows signal properly but i can't make or receive any call. what i think may be the cell is locked on T network and there's another option of 3g and some application just show something in korean with USIM mentioned. can anyone of you please tell me the possible solution for this issue and also where can i have stock rom for gingerbreag plus how can i install it on my phone.

help from you all is highly appreciated, thanks in advance buddies!

one thing more i am using windows xp.
except then one successful cwm recovery that was done on windows 7 on my office machine.

So it seems that you semi-bricked your phone.
To get it back working you have to flash an Nvflash compatible rom like V10B (if I remember right) and then re-smartflash to the ICS latest V30B.
I don't know why you bought an SU660. That model is made for Asia and I don't think it support the different frequences we are using here. They made it for that purpose. Good Luck!

Optimus L90 Unable to Root, Unable to boot into recovery mode

Hi
I have gone through the forums and can't seem to find solution for my problem with my Optimus L90 phone.
I have recently flashed the CM13 on my phone without any errors but below are the issues that I am facing
1. No cellular network signal after inserting SIM card.
2. I read in a different forum that this could happen due to using a wrong version of TWRP, so installed a newer version 2.8.7.0 but things worse.
3. Now I am not able to boot into recovery mode and phone just stays idle with the LG logo screen and few commands appearing like fastboot_iniy() and udc_start().
4. I have tried hard reset and soft reset and both are not successful.
5. I cannot root my phone either. Tried all ways like towelroot, purpledrake, lg root by avicoh etc but in vain
Now my phone, even though has a latest CM version I cannot use it for anything else.
Any help is greatly appreciated.

No SIM is hardly related to TWRP, probably you needed a different bootstack (there is a thread about it).
On CM you don't need anything to root, it's already rooted just not visible to common users, you need to activate Developer Options (it's also explained elsewhere)
Finally, if you cannot reach recovery but still can boot CM13 simply use adb, Flashfy or Hashr to flash another version or TWRP. 2.8.7 is kinda old and not recommended for Marshmallow, you can try 3.0.2 by SlimShady or DarkBlue version from shoxxy's thread.

Thanks for the reply, let me try options you have specified and get back if I am still facing issues

Sorry, I meant to say unbrick above

I followed the steps mention in the above thread to change the bootstack and was able to complete it without any issues, however the problem still persists and my phone is not recognizing the SIM and does not catch the cellular network.
Previously I used to use this phone with my t-mobile number and after I took a new phone haven't been using it for sometime. I want to sell this phone and was trying to ensure that it works fine and thats when I saw that the phone is not catching any cellular networks.
Please help. Let me know if you need any other details to better diagonize the problem.

You didn't say what model you have, maybe you flashed the wrong bootstack for your model (hardware version)? Be very careful, you can hart brick your device, and if it's a D415 it's very hard to unbrick. I'd suggest that first you make sure what model you have by removing the battery and looking in the label below, it says what model you have. Then, use LG Flash Tool to flash stock ROM (KDZ) to latest KitKat, then flash Lollipop or use OTA to update to latest version. The only requirements are that you make sure what model you have and flash the corresponding version, and the phone is still able to enter download mode.

[lfom]: thank you for responding. My phone model is LG-D415 . Actually my phone was bricked but I was able to get into download mode and then I used the L90 Hardbrick tool to flash stock ROM (KDZ) to latest kitkat like you have specified above. Then with the OTA update I was able update it to latest lollipop. Then I followed this forum below to to change the bootstack to KK 10C version as the issue specified in the below thread was similar to mine.

Image of the label inside my phone attached.
Do you think I should have used the LG flash tool to flash stock ROM. Should I repeat the steps with the LG flash tool ?
Thank you again for helping me on this.

Do you see your IMEI in the about phone page? Does it match the one in the label? Maybe when you bricked you've lost the phone's IMEI, and you can't get it back just flashing ROM...

Yes I checked and it matches. There two fields IMEI which has the number and then there is another field which says IMEI SV and it has a value of 02 in it.
