No matter what whenever I flash CyanogenMod I lost my IMEI. I've tried dozens of times go back to stock rom (IMEI FIXED) and the install CM and it always ****** the IMEI. I've tried first going to CM7 and later to 10.1 but even doing that 7 already has lost IMEI. This is driving me nuts. I've also tried recovering the IMEI from stock but it changes nothing.
I've found what's wrong:
1) I had problems with CWM. Was using a bad version or something like that.
So for anyone who is having trobble with IMEI lost, try the following:
Flash the original phone rom
Use a good CWM to flash the new rom (by good I mean the official one as the CWM list)

Hi everyone,
Today I updated my CyanogenMod Rom to the nightly of 05/13, coming from a nightly that was approximatively one week older.
Once I updated the Rom, the phone asked me 5-7 times for my Pin code, and I didn't succeded in acquiring cell signal . As I read from suggested in a thread (can't find it again sorry), someone suggered that the Modem wasn't right and to update it with the GetRIL app', so I did it, and the app' told me that indeed my radio modem wasn't compatible with my baseband and that I should download the modem it suggered. I did it, (the app' also proposed a backup of my current radio in case of bad flash, so I was kind of reassured), the flash was succesfull, and to try if the pin was working again, I rebooted my phone.
It didn't work at all, so I decided to revert the modem to the old one using the backup the app' created.
It was a disaster, I lost my IMEI, my baseband, and so on. I then decided to flash a stock firmware to repair that using ODIN, and it worked, I regained access to my IMEI, and to my cell phone signal. I then decided to flash the cyanogen nighlty from 05/11, but it broke my IMEI and connectivity again. Am I the only one experiencing such issues? It's not my first flashing a ROM and I followed scrupulously the procedure on the Cyanogen website, so if someone had a solution about it, I will be very glad.
Thanks for reading
Hello everyone,
I read countless cases in communities on this subject and I have tried almost everything, I am quite at a loss,
My case is like this:
I used SLIMBEAM version 4.2 or 4.3 (can not remember ...)
Yesterday I decided to upgrade to version 4.4.2 (now it is called SLIMKAT),
Somehow I got stuck in a loop of the BOOT screen when I tried to just install as I did,
Then i FLASH again to CWM latest version and then installation worked properly. (At the middle of the road I tried things - I've done FLASH to STOCK)
Even when I did the FLASH to the STOCK and the new CWM , I noticed that I have no connection/emergency calls only,
I tried installing a few different ROMs and some old and new versions of the STOCK and all the same.
What I saw on that network after upgrade is a bug regarding losing IMEI or serial number, but in my case when I went to the ABOUT -> the IMEI is correct (as written at the back of the phone) and serial No is not 0000 ....
I forgot to mention that for all installations I did -> I played with all kinds of modems also (Every time I tried something else someone said helped him in various guides on the net ...)
Any ideas how I can solve it?
Thank you.
[update] also tried the "ARIZA Patch" and nothing works.

Which version of stock rom did you use?
If you were on 4.3 before then 4.1.2 will get network problems.
For SlimKat, you can try patched modems. Links are available in efs thread.

Imei
The thing that I tell you since you the imei number intact is reset the phone to the original before being even worse things, find a guide on restoring the Terminal in XDA there are many and then you can again install whatever you want but first make a backup of the folder EFS.
Hello,
I've been facing this problem for days now, tried almost everything and still no luck, so I'm sorry if it's been asked before, but I'm truly hopeless.
Right now, my SGS3 works only on stock ROMs. Every time I try to install a custom ROM (JB or KK) I have a problem with the signal - either baseband, IMEI and everything is "unknown", or everything is good (IMEI not "0049...", there are full correct APNs) but it still displays the "error while searching for networks" message.
Fortunately (as I realized on other threads),I can always go back to square one, flash a stock 4.3, with no problems with IMEI or anything, but, you know, stock sucks.
I tried installing every modem I ran into, but nothing helped. Is there a secret step from stock to custom on samsung devices I'm skipping (I'm an ex-nexus user...)?

Same problem, no solution until now

When you install a custom rom, based on samsung 4.3, do you have emergency calls only/no network?
If yes, install Boeffla kernel 5.3/or beta 5.4 because Boeffla is a patched kernel i.e. it can read patched modems, and then install a patched modem .
From the on you will have your network (no emergency calls/no network problem) and signal should be good.
But first backup your EFS and store it on a very safe location, you have ann app for that, k-Tool on Playstore (requires root).
Hi guys, I must have read a hundred posts about this issue to no avail.
I recently rooted an old S3 GT I9300 using CF-Auto-Root and Odin. I was sure I backed up the EFS folder, but it would appear I didnt. Now I am runnning the Paranoid Android 3.0 ROM on the device with absolutley no mobile network/signal and although i have the IMEI written down the S/N seems to have changed to a generic 15 digit number as opposed to the original RCF**** or whatever it should be.
Ive tried Kies and re-installing a stock ROM which is both hard to get hold of and doesnt seem to want to unzip from CWM Recovery even after cl;earing the Caches and doing a factory reset. I've also tried re-writting the bin file using a hex code app and terminal with no luck, and EFS Pro only seems to make me think ive restored the EFS by backing up the already corrupt one and restoring that....
It is possible to rectify my EFS issue (nv_data.bin file I assume) with only a written down IMEI and no serial?? if so please advise... as Im seriously stuck and although ive considered using a friends efs folder im sure this is probably illegal...
HELP, Thankyou
oh..and...
It occurs to me that the guy to talk to is spocky12, yet i have yet to pm him pending your advice.... thankyou for any help i may receive..
Hi im also in the same position ive tried loads of stock roms for the UK as thats where i am... to no avail ive tried the original 4.0.1 rom all the way up to the latest 4.4.2 rom and each time the imei number is 0000999......... ive tried modem patches most of which are from looking through the xda site but nothing seems to work.... i could never back the efs up as when i had the phone it was in a constant loop so never knew which software/modem/firm it actually had on it as i could not get past the samsung logo. but since i have flashed latest android for the phone it will boot in fine just wont connect to a network and imei number is wrong ive been days trying to figure this out :crying::crying: Please Help!

Hi Dejay, its good to know im not the only one. have you tried using the Kies program to reinstall stock firmware, did that change anything? Also not sure if you tried this http://www.youtube.com/watch?v=JqLK_2I-SBM method but it didnt work for me, the HEx lines he refers to dont exist in my nv-data.bin.
Coincidentally, thats exactly how i acquired this issue, it stopped booting so i factory reset deviced, then backedup and rooted, then installed custom ROM and somehow lost backed up /efs .Im now showing an 000049 IMEI and tried modem patches, stock roms etc. and no luck. my serials all messed up too and i cant connect to any form of mobile network.
I just changed ROM again as i couldnt get the right Gapps to flash with Paranoid Android Rom 3.0 - now flashing Dirty Unicorns v3.8 from here and all working beautifully except no signal, wrong IMEI and S/N - I am by no means a PRO at all this and so im rather stuck like yourself..
Hopefully we'll be saved?!
Ok, so I used to have cm11 installed, but it got sort of buggy in the long run.
I decided to try Foxhound rom, just for kicks... When it was finished installing, I got the default IMEI and the phone wouldnt connect to the network. I found a way to fix this (without backing up my efs folder), by installing an old rom. After that, I installed ef extreme rom (the one with the s5 ui).. It was supposed to be the most stable and smooth rom... But the camera and hotspot wouldnt work -_- ... I never understood why.
Anyhow, the problem is, now that Im trying to get off that crappy touchwiz rom, I NEVER get service anymore. My IMEI will always go blank.. Now the baseband goes "unkown" too (which hadnt happened before)... For ****s sake, I was trying to go back to my old cm11, and still, crazy IMEI... However, if i install the old rom all over again and the region modem: boom, mobile network works again... I dont understand why it fails to work after i have gotten it fixed over and over again...
I even made a backup of my efs folder when the mobile network is working (on the old rom.. Revolution HD)... When i restore it on newer roms, the IMEI and everything comes back.. however, it wont let me access the network (radio off?)
WTF can i do? Im desperate for help, please!!
@niko: standard is to get your actual firmware from sammobile.com & flash it with Odin … to get a stable base.
Your device serial number is probably corrupted. You can use service box to fully repair this issue. Or you can flash Ariza's patched modem. It will work but your efs folder will be permanently screwed and you will be forced to flash it every time you flash a new firmware.
