IMEI unknown/lost after flashing - LG Optimus Black

I thought of having a new thread since I stumble upon a new problem. my previous thread was this: http://forum.xda-developers.com/showthread.php?p=27003308#post27003308
As the title says, after a successful flashing ( http://forum.xda-developers.com/showpost.php?p=23788913&postcount=170 ), my phone has no signal and found out that IMEI was unknown/lost in the process of flashing.
Is it possible for me to regain my phone's IMEI? I'm obviously have no knowledge in dealing with such things. And as I stated in the other thread, this phone was given to me by a relative abroad, so no box and unfortunately, there's no IMEI indicated at the back of the phone (under the battery) only it's s/n.
Any help is highly appreciated. Thanks.

The only reason to mess with IMEI is when you checked "erase entire CP" option in smartflash like stated here on the image http://forum.xda-developers.com/showthread.php?t=1448803 I have flashed my Black more than a hundred times since Froyo and never encountered IMEI problem.
You should determine what model do you have. What I can advice is read the stickies posted here. All of what you need to know and tools are already here.
You might want to try flashing another ROM together with the baseband "BIN and FLS" or through CWM a custom one and see if you regain IMEI and network. A topic is stickied about how. General Section is where you'd find. Flashing has been tackled many times.

Thank you kabayan for the reply. I did follow the instructions clearly not to check "erase entire cp" check box option (actually, it was disabled when I flashed) dunno what happened but it made the IMEI in an unknown status. I'll try flashing other roms. but for now, my phone is useless

Ok, flashed a Philippine version of v20b. got it from here (lg-phone-firmware.com/index.php?id_mod=1)
still has it's IMEI in an unknown state. where will I go from here?

I have noticed the following with my OB.
IF the phone is rebooted in airplane mode, the base band and IMEI is unkown.
Putting it out of airplane mode and rebooting, fixies the issues.
If it still does not, fixing permissions from CWM recovery works for me.

i think i broke my phone :( help needed

hi all
i thought i would attempt to flash my samsung s with the new beta froyo update.
i followed this guys tutorial.
( cant link to it sorry its the noobs guide with detailed instructions through kies and odin)
i used the odin approach
i managed to root the phone.
on reboot it asked for an unlock code (o2 uk) so i went on to try and follow the steps about unlocking it. which neither worked all the way through the steps.
on reboot it appears to have signal and in the about section it says i am onnected to the o2 network but when i try to make a call is says "data network not available with an ok button, which when pressed will return you to the ome screen.
any help would be greatly appreciated thanks
Almost the same problem,
installed 2.2 update successfully, the phone worked for like 3-4 days very well and after that today i discovered "Emergency calls only"
so the question now is did i bought phone which later was reported stolen? or somehow i broke it?
Anyone have any idea?
hmmm, I have the same problem! In the status menu, the number is shown, but the network, says "unknown"
Hi! I have this exact same problem except I was unlocking my phone using this tutorial:
http://forum.xda-developers.com/showthread.php?t=906255
But I didn't back up my Efs folder, now my phone is unlocked but when I put a sim card in it I have very little network and when I try to make a call I get " NO DATA NETWORK AVAILABLE".
I've tried everything but I don't know what to do!
I was thinking of two ways to fix it:
1. Reinstall froyo (not quite sure how using the samsung software as my laptop oesn't recognised the phone as a pone)
2. Downgrade to, get unlock code using market app and then upgrade to froyo again.
I know I messed up but now I really need to fix this.
Can someone PLEASE PLEASE help me out.

might need to change the modem in odin i think. just heard about it
did u try restarting the phone... just a wild guess...
I had the same issue before and was puzzled. Its actually a very simple solution:
1. Re-lock your phone, search through xda there is a code you have to enter
2. Unlock your phone
All done! Surprisingly easy
Try the Odin method in block 2 back to Eclair if ok then upgrade to Froyo .
http://forum.xda-developers.com/showthread.php?t=818556
However your non connection might be due to not flashing a firmware with your network settings in which case manual settings of APN .
If your IMEI has changed due to flashing and you did not back up your EFS folder then little hope but do a google / search of XDA as some have reported success .

Emergency calls only
I had a custom rom that was giving that to me too. I think it means that you can access a network different from your sim (because usually emerg calls can be made from any phone I think?).
I'd try and find a rom that is optimized for your carrier or at least a modem file from a stock rom that is for your carrier. You may also need to reselect the APN settings (or enter them for your carrier). Its under settings/wireless and network/Mobile networks/access point names (use the menu button to add an APN).
you could also try re downloading and flashing the rom to make sure that is the issue. Mine said it installed OK but never booted up, redownloaded and reflashed and then it was fine but the install screens looked identical.

Hi! Thank you so much for everyone's replies!
My IMEI isn't changed and someone helped me check my efs files and they are all ok. I'm going to try and reflash froyo through the samsung software to see if the network lock comes back and then try to unlock again. For this I'm going to unroot the phone and follow samsungs' instructions.
I'm afraid to relock the phone as there are reports that say it completely messes everything up!
But I'll keep you guys posted! Wish me luck!!!!
PS. Any other suggestions are more than welcome!
So, a quick update on my situation.
I uninstalled busybox and unrooted my phone using the oneclick root tool.
Did a factory format and, surprise surprise, my phone now works perfectly!
Apart from the fact that it doesn't connect to kies, but that's a whole another issue!
Tank you so much to all of you who answered my cry for help!

[Q] Galaxy Tab (Australia-Optus) Flash failed, now I have no IMEI

Hi all, I have messed up my Galaxy Tab GT-P1000 (Aus-Optus-CDMA) trying to flash. I managed to get it going on the following FROYO.XXJME Version 2.2 Kernel 2.6.32.9 rootatSEI-28 #1
Unfortunately I did not do a full backup!
My problem is now,
1/ No imei shown
2/ No serial number shown
3/ Not recognize my sim card
4/ Tab reboots regularly
Have done the factory reset however I am not sure if due to my flashing is it the original rom?
I have the imei written but cannot get the Tab to find it, thus cannot connect to Kies to get the samsung updates which would fix things, "I think".
Can anyone help
Thanks

Did you flash with ODIN?
Did you get an error message?
Have you tried re-flashing to a stock ROM?
You should read through the following thread before flashing anything else
http://forum.xda-developers.com/showthread.php?t=888071&highlight=no+imei+after+flash
And you are correct in assuming that a factory reset would only re flash the ROM you "replaced" your stock ROM with.
Also remember that using the SEARCH button usually will get you a lot more answers than just waiting on a reply here.
Did you unlock the tab first, no network lock, no sim lock... If you didn't this may explain whats happened. Don't know how you're gonna fix though....
Your Gtab is also NOT a CDMA tab, its GSM as you use a sim card... You may have bricked it if you flashed a CDMA rom.... Lucky if it starts up at all...
You need to tell us more info, what rom you flashed, how you flashed it - ODIN, Heimdall , Kies or just by pure magic. Then you might get more help....
the /efs folder contains all information/numbers about your gt including IME, mac address, bluetooth,etc.. It may have been deleted yet there should be a bak file inside the folder. since you are able to boot as you mentioned then you can still go into download mode and reflash a ROM?
Hi "theREDlegion" & thanks for your time.
Yes I did flash with Odin.
I got a red FAIL in Odin & an error message, trying to remember what it said exactly.
I am not sure which is the correct ROM to use for me here in Australia, CSC file & Pit etc, I'm kinda new to this stuff.......as you guessed!
I rooted the Tab with z4root, then used the repair nv_data to unlock the network which was succesful, so it said by entering the code.
So will the "Gingerbread" ROM work on my Tab?
I tried P1000XXJQ1_P1000XXJQ1_P1000XXJPZ_HOME.tar which failed.
Thanks again.
Hi ultramag69, appreciate your help.
I was installing a game when my Tab froze. No matter what I did I could not get it to respond. This is why I thought lets try & install Gingerbread. I managed to get it connected to the PC, however I am not sure if I did as you said "sim unlock". I did the network unlock. My Tab runs okay now but will loop boot when idol for 30 sec. I still whish to do Gingerbread if it is possible, or "overcome"
Thanks again.
Hi bongski55, thanks for your assisstance.
I have the backup of the efs & the files in it are dated 27/10/2010 which would indicate they are the originals. I have replaced the new efs files with these but still no change.
Not sure which file is the imei info though.
Here is my plan,
1/ Do factory reset - this will allow me to reroot
2/ Root the Tab & unlock network, learn how to unlock sim?
3/ Remove SD & SIM cards.
4/ Use Odin to flash with Gingerbread, I think I have the right ROM!
Wot u think!!!!!!!!!
Is your bootloader safe? Do you know what your original firmware version was ?
edit for my english: is "was" at the good place in the second sentence?
You've tried chainfire's safe rom, have you checked out the overcome thread, there's a safe rom you can install through ODIN there too... Might work. Also, do a search for Telstra rom, might take back to stock Froyo but with all the Telstra bloatware, I started on this.
After you take back to Froyo stock you can try again for GB. Can't say if this will work though as you have an Optus tab, mine was Telstra from the start...
Good luck...
Without restoring the efs folder CORRECTLY. All your efforts are futile. Follow this thread to restore /efs folder: http://forum.xda-developers.com/showthread.php?t=859914. Reboot your phone, Charge it and try flashing a stock ROM.
Some very helpful information has been posted here, thanks to the very helpful members of xda.
If I was in your shoes I would do the following:
1) Follow the link provided by DarkPal in post 10, complete the steps necessary to restore the efs folder.
2) Follow the link I provided in post 2 and confirm your bootloaders and take necessary actions to patch if necessary.
3) Your device (on Optus) should be WCDMA/GSM. I would go over the OVERCOME thread and follow instructions on flashing a stock safe rom and attempt to flash the OVERCOME rom. It is important to follow the instructions step by step for a successful flash. The OVERCOME guide is very detailed, if you follow it correctly you should not have any issues with the flash.
Do post back your results and good luck.

Thanks for your help so far,
I have been able to find the backup of my efs/ which was created during unlock process.
Thank god.........I have now done this, patched bootloader.
1/ Used Overcome safe rom & flashed
2/ Flashed to Overcome "Jupiter" v3.3.0 & changed file system to ext4
3/ restored efs/
4/ My imei is now back to original....Yippee....also is my serial number.
Now when I boot it gives me full bars of service & Yes Optus on the screen..Great!
But I still canNOT connect. My Wifi works fine.
I notice my IMEI SV is now 05 but was originally 01.
I am not sure how to see what csc I have & don't know if it matters?
Any suggestions....
Cheers
Google "optus apn settings" and check yours (settings, wireless network, apn).
Check if wireless mode is auto.
What is your baseband (modem version)?
Because you see optus on your screen, your voice service is fine, but no data connection means your apn values are incorrect or missing.

Good morning all, well I would like to thank everyone on this forum, particularly those who have promptly responded to my questions.
I am glad to say that after 3 days of stress I have finally got my Galaxy Tab back on the Optus Australia internet service, I had to change the APN from Optus (Internet) to Optus (connectcap) in the Access Point Names & also at the bottom of those settings I had to select Internet. The connectcap option is not there by default, you have to add a new APN & choose these settings. My sim card is a data plan only.
So I now have my Tab running Overcome Jupiter, thanks guys, love your work, on the ext4 file system and already it is noticably faster.
Now......probably a good time to do a proper backup......yep I'm learning!
So thanks again everyone.

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

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.

p1000 baseband unknown - nothing seems to be working

I have a factory unlocked P1000 that recently started having some issues. When I first got it two years ago, I had flashed it with the following:
PDA1000DXJK2
PHONE1000DXJJ2
CSC1000OLBJJ2
During all that time, everything was working fine everywhere I had been (Asia and North America), with at least three different SIM cards and carriers.
About three weeks back, I suddenly lost voice/data. At first, I thought it was a SIM/carrier issue, but some swapping with a friend revealed that it was my tab that was the problem. Searching here and elsewhere, all I could come up with was that my IMEI was showing as the generic 0049990106400 and not the one listed on the back of my tab. I had been aware of them not matching, but it had never caused problems in the past. I was able to confirm, however, that the radio/modem was still working. I could place emergency calls, I could see that the networks were there, I just could not connect to any of them.
In my attempts to restore the original IMEI, following a guide here, I managed to lose my broadband entirely. I have been researching and trying to get it back ever since, so far to no avail. Unfortunately, I haven't been able to find a copy of the P1000DXJK2/DXJJ2 firmware I used the first time. However, I have tried multiple stock ROMS, different tutorials, and most recently, flashing with Overcome 4.1. The result is always the same: everything works except for the phone. Phone, broadband, and IMEI list as unknown.
Currently:
PDA: P1000XXJQ1
PHONE: Unknown
CSC: P1000OXAJQ1
Model number: GT-P1000
Firmware version: 2.3.3
Baseband version: Unknown
Kernal version: 2.6.35.7 [email protected] #2
So, here I am desperately appealing for any help anyone might be able to provide. My tab has been my only phone for years and often my only internet access, so I am feeling pretty lost without it. I am fairly tech savvy and I follow instructions very well, but I have never really messed around much with Android, so I am hoping the experts here are going to be able to come up with something.
So, you said you most recently use overcome 4.1.
When you first use Odin to flash GB-stock-safe-v5, before you put overcome kernel, what is the IMEI?
No point to proceed to Overcome ROM if GB-stock-safe-v5 didn't bring back the IMEI.
Yes, that is what I assumed, but I gave it a try anyway. If nothing else, it gave me better recovery mode tools.
As I said above, nothing has worked so far. My IMEI was unknown before flashing with GB Stock, as it is now. However, at this point, I would be happy just to get a working modem again, even if the IMEI remains messed up... One thing at a time.
the fact that the IMEI suddenly is gone, and on further tweaking the radio/baseband is gone, I think your internal storage is failing.
first it hits the EFS area, then the baseband area.
That is my suspicion.
You could probably proceed to flash latest CM/AOKP or whatever, which repartition your internal storage.
You should get your baseband, because the /radio/modem.bin in those MTD partitioned ROM sits on a different part of the storage.
But since you never have a backup of your EFS, those ROM will not give you your IMEI either.
Only flashing a stock ROM will give you the right EFS (assuming the area it writes into is writable)
I also wonder if there a person expert enough to rewrite the pit file, so that your EFS and baseband is shifted from its original position, and use that with the GB stock safe v5
This is an interesting idea. To clarify, though, my IMEI did not suddenly go, to my knowledge. For at least the last year and a half, the IMEI listed did not match the one printed on the back. Everything worked fine, so I never gave it much thought. What I do not know is if it changed again, or if it has been the generic one I listed above all along.
Could it be that something is simply wrong with the EFS, preventing the modem.bin from flashing correctly? One of the IMEI restoration tutorials I attempted early on involved messing with the EFS. I believe this was the same night the modem stopped working, though I did not notice a direct cause-effect relationship. There were other (failed) attempts between that and broadband coming up "unknown." I will admit I was a little hasty in those first few days. I was traveling, crunched for time, and panicked that I would have no phone.

Unknown IMEI and locked network after trying to recover

Hi everyone,
Hope you can help me solve this, cuz I'm way out of my knowledge..
My phone broke the lcd and was out of action for a few months.. After I finally got a replacement screen, the phone wasn't working and said IMEI unknown, I've tried to flash a few roms via recovery but nothing. So I just went crazy and flashed it via kies. It worked, the imei appeared but the phone was locked again..
Back to the shelf a few weeks until I could afford to pay for unlock.. When I picked it up, it was unknown IMEI again and the guy at the shop basically told me he couldn't help.
Was he right? I refuse to believe I can't recover the phone.. Can you please help?
Thanks!
Anyone?
Are you sure is that phone imei is not blocked, because provider may block if it is stolen reported.
I had the same problem after changing display IMEI unknown
But somehow it was saved from 'unknown IMEI' I don't know how.
restored efs from previous backup (twrp & philz recovery)
- no imei
I flashed stock
- no IMEI
asop
- no imei
tried different modems
again stock
- suddenly its worked
(some users reported flashing different modems worked for them)
Yes I'm sure imei is not blocked by network. Have a friend that bought a phone which he discovered the hard way it was stolen, anyway, blocked imei by network behavior is completely different.
This is what happened to me first time only valid imei after kies rom update.

If you see imei again, Make a backup using pc, there is a guide in development section. So, you can easily restore again.
