this method works for me, but I am not sure if it will work for you. I have to warn you that I am not a dev, I am just a basic android user. I came up with this idea out of desperation because my phone cannot receive and make calls for almost 4 days. so do this at your own risk.
note:
* make sure your phone is rooted.
* make a copy of your old efs backup and all your important files in your computer or in a flash drive.
1. copy and write on a piece of paper your imei # which will be found at the back of your phone. it is 15 digit
2. copy your efs.img (not the folder that contain the efs image) to your internal storage. it is about 20mb. if there are two files then copy both.
3. connect to wifi and go to playstore and then download and install the IMEI Tool N7100 by Dr Ketan
4. download and install xposed installer and make sure to install update.
5. go to this thread and download and install imei changer
http://forum.xda-developers.com/xposed/modules/xposed-imei-changer-t2847187
make sure to activate it in exposed. then reboot your phone.
6. using ES File Explorer or any file manager with root privelege, go to /efs and delete all files
7. open imei changer then input your imei # (the one that you copied at the back of your pbone) then save. to make sure that your imei has changed dial *#06#. check if your imei if its the one you have written. if not go again to imei changer and change then make sure to save.
8. open IMEI tool by dr. ketan and restore efs backup. it will ask for root privelege so click grant.
9. after restoring efs, reboot to recovery and wipe cache and dalvik then reboot. check if you have data connection.
10. if its not working then go to recovery and make a full wipe and install new touchwiz rom (i used DN4 when I did this, but its up to you whatever you like). and repeat the steps.
* that's all I did mate. there is no scientific explanation about the process that I made, but when I did those things, my phone is working fine again. hopefully it will work for you brother. Good luck and God bless!

I followed the same procedure but did not worked.
One more thing i would like to mention that in recent past i got my complete pcb replaced by samsung service center but imei was same. and the backup of efs which i did was on previous pcb/motherboard. could that be the reason i am not able to restore imei?

Best Working Solution
Mahn I just love you
You just saved me.
I've tried every possible solution but your's worked for me.
I had lost my lenovo a3300 hv 's imei when flashing official rom, but now its working fine.
agian Thakns a Lot !!!!!!!
Hello, this is really weird. In fact, when I insert the SIM to my Note 2 N7100 and turn it on, it allows me to make emergency call, but I cannot use it to make any others and it doesn't show the carrier name (it shows Emergency call only). And when I try to use it to make normal phone calls, it says that I am not registered to a mobile network. I try to factory reset my phone, but the problem remains. I then try to remove the SIM card, and it says that I need to insert a SIM card (that means that it is not a hardware problem since it recognizes the card). I then try to go to the mobile network setting to try to connect to the network manually, it connects me but it shows me a warning which says that the mobile network service is not available (and the Emergency call only label remains). However, I am sure that this is not the problem of the card neither since when I insert the card to my Moto MB860, I can make calls as usual. So, what is the problem ??? It seems to me that the problem happens spontaneously since it works perfectly until yesterday. And all other wireless function works fine including wifi , Bluetooth and GPS and the only thing goes wrong is 3g and 2g.
Additional information:
ROM: Omega v.16
Carrier: Fido Canada (as you can see)
Thanks.
First of all, check whether you can see the IMEI of the device. If you can see.
1. Contact your network operator and check whether your IMEI is blacklisted or not.
If you cannot see the IMEI
1.Restore the efs and persist backups (if you have one)
2. flash the device again with the modem image (download the firmware of your device from samfirmwares.com, delete everything from the .tar file except modem.bin, and then flash this file to the phone with Odin (you can get Odin and instructions from that site or from here)
2. maybe your nv_data.bin file or /efs directory got corrupted, make a backup of the folder, then simply delete nv_data.bin, it will be recreated for you.
For this, you’ll need root. If you have a root-enabled kernel, you only have to install the Superuser app and Busybox on the phone, download the Android SDK to your PC, install platform-tools in the SDK manager, go to the platform-tools directory and start adb shell.
In the shell, type su, wait for the Superuser prompt to appear on the phone (if it does not appear, open the Superuser app and try executing su again), enable root access for the command. Now go to /efs, copy everything to for example /sdcard/efs, then rm nv_data.bin.
Reflashing the device with a kernel and checking “phone EFS clear” in Odin also works (make sure you made a backup of the EFS folder just in case).
3. you can try changing the CSC: enter *#272*imei# on the phone tab.
Try this . I'm not sure it works. Just give it a try on yourself.
Trying the above mentioned methods could be vulnerable to your phone if it not done properly. So do it carefully. If you have any doubts feel free to ask me or search elsewhere. But, don't blame me for a fully dead phone. I am not at all responsible for any...
Noob 1st post......have had similar problems with koodo CDN
Not gonna give such an in depth suggestion as above.....he's something simple to try.
I live in a dead zone and often my phone ( galaxyAce) will switch to no service. Even after refreshing and selecting network under settings, it says it's connected, but isn't. A simple apk that always fixes the problem for me is Network Signal Booster @ theplaystore

I need to get the firmware first... since I already passed the download quota for today... need to wait until tomorrow...
Mmm... I heard that you mentioned clearing the EFS in your given procedure, but I do not think that I modified that folder... However, about few days ago, since I want to gain better control on the volume on my headphone remotes, I did modify the file called Generic.kl in system/usr/keylayout, but I restore it after since it didn't work. However, I don't think that this modification will trigger something in the efs folder since it has different directory. By the way, I did some research online and they say that the efs contains information about the carrier on the phone, so will there's a greater chance that the problem is caused by the possible modification on the efs than any other factor and will there also something else that possibly trigger the similar effects?

One question: is it device-specific (i9500) or can we use it on other Galaxy devices (I have i9305)?
I used this tool to backup the EFS and later on after flashing a custom ROM when i restored the backup i didn't get back to Service and the IMEI Was still NULL

I already discuseed this, you need to restore your EFS backup after you flash the ROM that you made the backup with.
so flash XXDMF1 with ROM XXDME6 (or DXDMF1) and then restore EFS.
if that didn't work. then flash XXDME4 then OTA update will give you XXDMF1.
If you can't recieve OTA updates and you have Root, then tell me so I send you my XXDMF1 and DME6. (dr.ketan has DXDMF1 which you must try first).
After every flash restore efs then restart to see if it is fixed.

first of all make sure your phone is rooted. then download mobile odin Pro (you need Pro version to maintain root or simply root again). then download this file:
http://www.mediafire.com/download/ena68zhyjhwpc78/update.zip
Edit: this will make your mobile a french mobile, so don't flash it just get someone to convert it to a modem.bin or modify it for your country.
now open mobile odin pro and flash the Stock ROM XXDME6.
after it finishes open mobile odin pro again and go to update file, and choose the file you downloaded above. then flash it.
you you have build number XXDME6 and buildbase XXDMF1
now restore EFS by using this app: https://play.google.com/store/apps/details?id=jackpal.androidterm&hl=en
Code:
Put your EFS file on your mobile (External SD Card is preferred on the Root of the Card, so its location should be /storage/extSdCard/efs.img).
name it efs.img for easier use (if it was an img file).
now in the terminal type this:
SU
then grant it superuser permissions.
then type this:
dd if=/storage/extSdCard/efs.img of=/dev/block/mmcblk0p3 bs=4096
it will show you numbers if it was done correctly.
then reboot your phone and everything should work correctly. Reboot again to make sure.
In case it didn't work, then Flash the DME6 ROM, it should come with DXDMF1 , then try restoring EFS again.
tell me what happens with you.
@mysterionTM

what do you mean permanent way? why would you need DME4 if you have a higher better one?
you can flash DME4 (it comes with ROM DMB4) modem alone and keep it permanently, but if your EFS backup was when you had anything other than DME4 then you can't use it anymore, you have to recover EFS everytime.
just use XXDMF1 (since your CSC is DMF1) and restore EFS. don't see any reason to use an old modem.

on your other phone , you had EFS backup on DME4. on this phone, your backup is on DMF1. DMF can read DME backups, but DME can't read DMF backups because samsung changed the EFS read type on DMF1. so once you go DMF1, your EFS partition is changed permanently!

you're wrong
I was only backup on DMF1 on the other note 2
I followed this procedure and are able to put DME4 :
1. make a copy of your EFS folder using root explorer and store it somewhere safe (on your SD card and external SD card should do it).
2. delete the EFS folder from the root of your phone using root explorer.
3. reboot the phone
4. open root explorer and go to the EFS folder (yes, it is still there! The Android OS has generated a new one for us) and delete the following files:
nv_data.bin
nv_data.bin.md5
nv.log
.nv_data.bak
.nv_data.bak.md5
nv_data.bin.bak
and the entire IMEI folder.
5.Now go to your backed up EFS folder on your sd card and copy the IMEI folder and the " .nv_data" file (note the dot) to your new EFS folder.
6.Make another copy of the ".nv_data" file in your new EFS folder. Rename one of them to "nv_data.bin" and the other one to "nv_data.bin.bak".
7. Connect your phone to your PC and start up EFS PRO. After your phone has been detected, press the "Repair nv data" button to correct the ownership and permissions.
8. Reboot your phone into recovery mode using the three botton combo and flash the original modem firmware (the modem.bin file that you extracted earlier) to your phone using Odin (use the "phone" button for the upload) or Heimdall (use the "radio" partition for the modem.bin file upload).
9. Reboot the phone normally and your IMEI number will be restored and you will be able to connect to your mobile network again
but on this note I can not!

oh, you followed the folder method! then yeah it works, but not recommended as it messed up permissions.
I was speaking about the mmcblk0p3 method.
how to know which modem i need? Im on stock firmware 4.4.2, Malaysia. Have the imei issue/corrupted efs and no backup
I need experts review and help to resolve my issue last night i am update my phone s20 ultra G988B/ds to its original software everything working fine except network i was using root phone it was fine on all networks but after updating my imei status goes to NG(not good) sim accepted phone but shows emergency calls both imei shoes but network not working plz give me suggestions and issue solution. I am again root my phone but still not working networks plz help
S20 ultra imei status NG
Why you experts not solving my issue no comments at all?
Bro i've posted same kind of post just now i hope someone replies soon otherwise i'll try z3x software or chimera and let you know about the results, i think if your imei is not corrupted then cert file will do the wonder.

did you guys resolve it ?
i may have an idea
Any fix
do you guys even search before asking?
First, do a TWRP backup, all partitions including efs & modem.
Open the root explorer app, open the efs folder, delete the files named nv_data.bin
, nv_data.bin.md5 & the folder called imei. Then open twrp, wipe all partitions. Flash the latest firmware with Odin.
That solution work???
