Dear xda-developers users:
I have recently flashed the cyanogenmod 11 rom in my U8800 pro, following the instruction on this thread. (Installed TWRP and so on)
Everything worked perfectly, but in the process I lost my IMEI.
Sadly I have not a backup of my IMEI (I trusted the upgrade to go smoothly), but I have my IMEI number written down on the phone behind the battery. Is there a way to "reflash" my IMEI?
I found guides explaining how to do this, but all of them required to access some sort of service menu that is not avaliable on Cyanogenmod. Can you please explain me how to restore my phone to the original ROM (I have really no clue on how to do that!). Also a procedure to recover my IMEI without restoring the original ROM is appreciated.
Thanks in advance.

I tried to install the new version of CyanogenMod Snapshop but unfortunately afte the reboot of my LG G2 D802 the mobile phone bricked.
I read a lot around the Internet and finaly i succeeded to unbrick it. Th problem now is that i do not have IMEI (is null now). I read that there is one program that you can fix your disappeared IMEI but cannot work in my personal laptop. Do you know anything how to repair and fix my IMEI with my previous official IMEI (i have it in the box that i bought but i didnt have any backup of it).
Thank you
I am having the same problem. I was loading a milestone version of a rom and when it loaded after wiping there was no service whatsoever and everything is null. I understand it wiped the efs and I dont have a backup. I also understand that we can change the info back with the numbers off of the original box using dfa cdma tools. I have the program but my question is the 000000 code does not work when i try to unlock the phone. Anyone with any experience with this program that can help me to re write my meid???

Which program do you have?
Dfs CDMA tools
I don't have any personal experience with this, but I have done a ton of reading on this problem and it's become my biggest fear. From what I have gathered you have very very little chance of fixing this yourself. It most cases it goes back to the manufacturer. Can you tell us exactly how this happen?
I have no idea, i have been rooted for months and swapped roms like crazy. I wiped and installed a new rom and then it was getting no service so i tried to update profile and said it couldnt. Then check in the settings for the baseband and meid and unknown was shown across the board. Trying to figure it all out now!
I have had the same thing happen what cm did u install I had a d802 version on my ls980 restored it but now it will only accept a d802 modem and the signal is weak and drops out but it did show my ESN and imei and baseband again instead of unknown if I would have flashed it with a ls980 modem

Have you tried restoring a backup?
Sent from my dr87 v7 powered, Mahdified LG G2 (D801)
My problem started when I tried to update my LG G2 D8002 to the latest Cyanogenmod Kitkat Snapshop and i stuck in clockworkmod recovery loop after returning in CWM to take backup. I tried to connect it to my Laptop but i cannot have any access in my files via my laptop. The bad thing that i did is that i formated everything in my mobile (as you can see and my IMEI too) to make a clear installation of a new rom after the brick. When i entered my new ROM i realized that i have everything apart from my IMEI. So that i do not have any network-signal in my mobile but a connection to Wifi
The program Dfs CDMA tools and Octopus Box does not work in my desktop. (Any idea?)
Do you have any idea how to repair it? I read that there is a folder (nfs i suppose that encode inside the IMEI). So, if someone find this folder can upload it somewhere? Probably will find a solution to solve it.
i was solved problem with no imei :
make full buckup from TWRC in another LS980
restored that buckup in bricked phone (make first buckup on it, to know name of folder, and take to that folder buckup from work phone)
sorry for me English

Hi
Im also facing the same issue after flashing the CM11 from Blefish on my U8800 (not pro)
Unfortunately, for now the only fix available to us is to reinstall the stock rom, use the IMEI backup tool and then reflash the custom ROM.
I haven't done that yet as my phone is still working fine (IMSI and the serial no. is being used I guess)
If I find a fix will update, thnx anyways

Do you a have a efs.img backup ? Or any kind of IMEI/EFS/RADIO backup ?
I had the same problem I flashed the stock ROM and somehow I lost my IMEI info, I tried everything and I was even thinking about buying a z3x box but then I decided to do a very risky move , I completely deleted all the EFS related files/info and reflashed again but now I was not able to boot because I always sent me to recovery mode saying that :
"E:Failed To Mount /EFS (invalid argument )"
Then all I did was installing TWRP and rooted my SM-G935F and then I placed my efs.img backup on my internal SD CARD and went on recovery launched the terminal and wrote this :
dd if=/sdcard/efs.img of=/dev/block/platform/155a0000.ufs/by-name/EFS
Then I wrote reboot and it finally my phone was booting and I recovered my IMEI and was able to use my phone normally.
This only works if you have a backup of your EFS, and even if you do is risky , but I did it because I lost all hope and was accepting the fact that my phone would just become a useless wifi only device .
So there is not a fix yet for this problem ?
I have a problem on my s7edge instead. If i have valid imei i'am almost always in emergency calls, and when the signal comes back does not go into mobile data connection. With the wi fi no problem.Can someone help me i'am going crazy.!

Hi
I am ready to donate if any expert can help me to restore IMEI.
I am using SM-N9500 samsung note 8 model - hongkong version, i frequently change the roms.. when last time i tried to install a custom rom i lost IMEI. i am getting error like IMEI-unknown, baseband- unknown, no network and sim cards not working..
i tried installing stock rom, custom roms, it was installing successfully but only baseband, signal and IMEI are not working. i didnt even back up my EFS folder. So, kindly help me to get back my IMEI.
I have installed stock rom, still no IMEI. now i rooted my mobile and taken EFS backup. is it enough? if yes, pls suggest me the next steps. I also tried installing combination firmware, though is not working, installation was successful and also i am able to see the factory binary logo, after which it will switch off automatically and boot loops. everytime it will open factory binary and immediately it will switch off automatically..
Build number - R16NW.N9500ZHS4CRJ1
Hello everyone, I have a problem with my device, after installing 8 android and returning back was gone, I tried to restore it via persist sdes on the forum by the instructions like it turned out but then got the update over the air and it again became zero but the link worked decided to restore it via pixel but even on the pixel it was 0 can I return native firmware with normal imei sorry for my English
I have the same issue. On pixel room after all the instructions, but still no imei. Even after erasing modemst1/2 in bootloader.
I don't know why so many people are trying to restore IMEI with persist instructions. It is not meant to do that, and is only necessary for those who lost volte after getting back
service. If you do not have service and an IMEI of 0, adding the persist folder to your EFS will just further corrupt it. No where in the original instructions for using persist did it say to use it to fix IMEI 0.

Hello everyone, recently I've flashed the Superman ROM V.3.0.1 and everything was fine until I went to general settings on my phone and saw my IMEI is now UNKNOWN. I know this thread may be already solved, and yes, these days I was looking for answers for my problem but I need to know for sure what alternatives I have to recover my IMEI. I have to mention, my phone is 100% original, it has its own IMEI from the beginning, not a copy or MTK device. I saw some sollutions based on some kind of programs to restore manually the IMEI with a command, and this method for me it's not like the best thing to do in this situation..
When I am dialing *#06# I receive the following information: " SM-G935F is not supported on showIMEI ".
I've checked through TWRP ( version 3.1.1.0 ) the partition EFS, is still there ( it has 2mb ). What do you guys think about this? Flashing the stock ROM from sammobile may solve my problem? What alternatives do I have?
Thank you!
