Need Help "LOST IMEI and Baseband Unkonwn"
I was using Euporia 5.0.1 on LG 4x
I received update notification and I downloaded Update.zip ( which included to 5.1)
By mistake i flashed the zip directly from CWM ( without Formatting any partition )
after restarting there was no IMEI
Following things I have tried
1) Trying to flash Original V20C KDZ. via LG Flash Tool. ( I think it checks for IMEI , and that's why stuck in between)
2) Use LG Software Update tool. ( also can't progress with IMEI)
3) Flashed Original V20c Flashable zip from CWM (But it didn't restored my IMEI)
4) Contacted LG Service Center, and They say You need to change whole Motherboard. ( I was Shocked to know that )
:crying:
If anybody went to same problem. and resolved .
Please Guide me.

I dont think that fleshing update.zip had anything to do with losing IMEI since you cant update 5.01 to 5.1 without wiping u will just have many bugs but u wont brick u device.I think it is hardwer problem my friend on his lg 4x have similar problem (no IMEI and cant connect wifi to any network).

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.

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 ))

this is also the best metod for unbricking your phone, .
INSTALLATION:
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)
http://www.putlocker.com/file/4CEDEB7E0893B6F1
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
Appreciate all help.

[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

Code:

(credit to proper uploader, I dont remember where did I get it, sorry)
The problem causes by LG update software when you kdz from 20A to B or C.

Bests of luck.

[Q] LG 4x p880 IMEI null sim card problem

Hi folks, I have problem with my LG optimus 4x p880 phone. Today phone doesnt read sim card. I discovered that when i asked my imei number via *#06#, it said "null". So my phone cannot connect the operator. How can I fix imei null problem? Thanks :good:
none knows?
I had the same problem...
In my case, as far as i can tell is hardware related.
At first I thought it as a bad flash, so i tried (after reading every possible threads) to flash a stock kdz.
I cant flash the kdz, because stucked in 10% (error 207).
So i opened the phone, checked if the connections were ok.
Didn't work... Still stucked in 10%.
So i used brute force, and start to press the phone very hard near the edges, near the the sim. Magically the lg flash tool pass the 10% and flashed the stock rom.
But the null imei and baseband persisted.
I tried once again the brute force and it works, but i cant turn off or reset the phone, because the baseband and the imei return to unknown
The connection take some time to occur.
Hope that can help.

Does it work everytime you press the phone? When do you start to press exactly? (e.g. during start up?)
What 's the exact location to press?

Not every time, but work 1 in 5 times. With the phone off i remove the back cover and start pressing near the edges, and near the SIM, then i turn on the phone still pressing. I keep pressing until the phone signal appears. Normally i wait 5 minutes, because sometimes when the phone starts the baseband is still unknown, but then, like magic the signal returns and the baseband and imei appears.
However, when i turn off/restart the phone the issue returns. (very annoying). Hope it works with you.
