TD:LR Get back to Stock ROM for your country and then restoring EFS the backup will help in getting back your IMEI.

Requirements
1. Stock country ROM + Rooted if necessary
2. Any EFS backup
3. Same tool used in (2) to restore it back.
Situation
Currently I was 4.3 XXUGML2 ArchiDroid V1.7.3. Faced a lot of issues with any 4.3 ROM i tried. So I though I will go back to 4.2.2 OXAME7 [EFS v1] which was real stable for me. I flashed 4.2.2 again via Odin. After successful boot I had lost my IMEI where the code was generic 0049***. Here are the things I tried to do:
1. I had efs.tar.gz file which I had created when I was on 4.2.2 before flashing 4.3 with help of kTool. I tried to restore the same with help of the same app, but that did not work at all.
2. I had made EFS backup via custom backup and restore of Philz CWM Recovery. But that backup was in Internal SD. After I had flashed 4.2.2 from 4.3 with Odin the internal was completely wiped. So I had lost my 2nd and final alternative backup.
3. Tried to flash XXEMG4 modem which is actually EFS v2 modem, but that too didn't solve the issue.
Now why did this happen?
I am not sure, but my guess was that this happened because the 4.2.2 ME7 ROM had EFS v1 path whereas the 4.3 ROM was EFS v2 path. Any other possible reasons?
The Fix
As a last resort
1. I downloaded the Stock ROM for my country (India) which is XXEMH4 via odin --> No IMEI yet
2. Tried to restore the EFS via kTool again.
3. Profit + hefty amount of relief.
It was a great relief for me to see the IMEI back and thought of sharing it here. Hope this information will be helpful to others. :good:
Edit:
I think this method too would have helped, but did not bump into this thread earlier: http://forum.xda-developers.com/showthread.php?t=2531221
Well this work with S4 too?

I'm not sure.. But flashing stock ROM and then restoring EFS can be applied to any Samsung phone with IMEI issues as last resort.

If you are in I9500 you are in a knox free bootloader , you can do whatever you want , root , install custom rom , go back to stock ..no knox .
Just do not upgrade the bootloader , no stock upgrade , no OTA
Towelroot does not work on exynos processors, stay on 4.2.2 use stock base roms if you like the stock TW look

Anything you want ....cm , tw any version 4.2.2 , 4..3 , 4.4.2 , 4.4.4
Root , install a custom recovery and flash.....
If you want to go back to stock use only 4.2.2 stock roms so you do not upgrade the bootloader ( preferably the same one you have now) , backup before you do anything , do not forget to back up also your efs folder

1: Try it and find out. I can't answer this as I have a i9505 and rooted it using Towelroot.
2. The EFS folder is where the device's IMEI and other relevant configuration data are stored. If the data is corrupted either a nandroid backup or a copy of the EFS folder contents should restore the device to working order.

Hi,
You can use cf root or flash (odin) philz touch and once there go to Philz setting and chose re-root system
The efs folder is not backup by nandroid it must be done separately you can do it with philz recovery Backup and restore/custom backup and select efs or use apps like Galaxysim unlock , it has an option to do it what is is well describe by @Strephon Alkhalikoi in the post above this , once again towelroot does not work in exynos S4
Thanks for your time! Am familiar with cf auto root, but Philz one seems easier as I also get recovery with it, can u link me to Philz recovery and root?Again huge thanks, am not using towel root?

@MAX 404: I'm running TWRP. Why then do I have "efs.info" and "efs.ext4.win" as part of my nandroid? Or is EFS actually hidden and what I got from the backup was only the files I could see?

That is easy , Galaxysimunlock and philz will do it for you provide you have the backup Both app will create a folder where it will put the backup( galaxysimunlock or clockworkmod) , make a copy and save it in the pc, when you ask to restore they will go and look for it in those folders and do everything ,

there are different ways and apps but for me this 2 are the easiest ones

Not an expert on twrp , maybe they do include efs in their back up , which is brilliant , on philz is not part of the regular nandroid , you have to request it from the custom backup section.

Neither am I apparently.
The EFS backup in TWRP was only about 13KB, which is way too small apparently. I just downloaded Samsung Tool and used it to make a proper EFS backup. The final result was roughly 13MB in size, which seems more like it.

One more doubt, the Philz recovery will be a. Tar file, I put my phone in download mode select pda leave all rest same and flash till I see pass. Right?
Hello Fellas, am posting here as I haven't found help elsewhere. Kindly Respond to my woes. I have a rooted Galaxy Note 3 N900 running official Lollipop with IMEI Null/Null and No Baseband version. The IMEI just disappeared totally out of the blue as no custom ROM has been flashed on the device!! This has happened 2 months after updating from 4.3 Jelly bean. With no prior EFS Backup here's what I have tried:
1. EFS Professional (backup&restore complete but no luck)
2. EFS Restore express ( backup.bat>Odin restore)
3. GSII Repair tool
After hitting no luck with the above tools and without any "/EFS mount errors" in recovery either and WIFI working fine, I came to a conclusion that most probably the EFS folder partition on my Note 3 is still intact and most probably this could be a case of a bad modem which would explain the loss of Baseband Version and thus the Null IMEI. So I tried flashing back to KitKat with N900XXUENG1 firmware and separately flashed a few modems compatible with Samsung's new EFS System: N900XXUENG1_MODEM, N900_XXUENF2_MODEM_CWM and also gave a shot at recommended N900_XXUENE1_MODEM_CWM.ZIP which seems to restore baseband for many users with this issue but this failed as well. After much searching I found a 4file_N900XXUGBNL8 Lollipop Firmware with PIT from Dev-Host, flashed all files in Odin&even repartitioned the device but still no baseband!!! WIFI&everything else runs smooth except the damn baseband/Null IMEI! Almost Exhausted my options...
Now I trust we have some informed members and developers here, NEED YOUR VALUABLE IDEAS HERE mates! Someone, anyone.....Thanks!
Have got any guarantee of the device?If so,send it to service ıf your guarantee continiues.
If you bought the device from another country,This may occur ıf you didn't register it.(In my country this is how it works.Turkey)
Or someone cloned your imei,check your imei ıf it is valid.
This is not because you upgraded your device to android 5.
If ıt was the case,you would have already faced the problem after just the flash.
I would say flash another modem
But,You say you tried flashing other modems.So no luck with that.
I had seen s3 with the same problem.I had flashed a modded modem.
It worked.I dont know if there is one for your device.
Briefly this is an imei/modem problem.
I don't know ıf the suggestions above help you.
I hope so.
Good luck.
try flashing stock rom from sammobile via odin. you need to backup efs folder everytime you flash a new rom, that's my opinion. may be wrong.
I think I used to had this problem with my Note 2 as well. If you come from 4.3 you should flash stock ROM Jelly bean 4.3 from Sammobile or Samsung-updates website. Then flash lollipop 5.0 over 4.3 when you can see your IMIE. Maybe it will work.
So. If u in L bootloader. U must! Flash the L modem that sometimes didnt get flashed by the odin while flashing stock rom. So just extract the modem.img and things for modem. Then just flash it using dd command or make flashable zip. Then it works fine. I have it on s4 exynos. That if i in L bootloader then even i install kitkat rom with L bootloader. U must still flash the L modem. K. Hope it works
1. İf you couldnt recover with efs professional , probably you've been lost your original imei files like nv_data.bin etc. and there is no backup...
2. So try to remake this kind of files with-again- with efs professional. But there is not so much info about this "creation" process.
3. I had the same situation. . . . And i'm still sorry. . . ( . . . The other solution is JTAG, more easy, cheaper in total and psychologicaly healty !!!)
GOOD LUCK....

Thanks for that but as I already said I was lucky to find a 4file partitioned Lollipop ROM with separate modem. Flashed that through Odin and even repartitioned the device but that hit a rock as well!

It's an old device, no warrants. Am indeed looking at the possibility of someone else allocating the IMEI to their device, though i doubt. But if that was the case shouldn't the Baseband at least be present?
Did you try downgrading to 4.3 with official stock files?
If not,give it a shot.

I have explained it earlier, Actually it is kernel. Newer kernel makes some changes on EFS partition and that changes can not be read by old kernel but in this case once you flash newer modem it will be solved. If your issue doesn't solved by flashing latest stock ROM then only possibility is messed up EFS partition and for that you must have a backup which was created when your device was normal. If your EFS partition is corrupted and you don't have backup then i think only option you have is to go to service station they can repair it easily. Though your device is not under warranty but you have official bill then still they can do it with paid service. Now a days samsung have changed policy and restoring IMEI they needs to do it online with samsung server (this information I got from service center owner in my city who is my friend and he did same for one of my friend)

Thank you Dr.Ketan for that information. You have been a great help to many. I have followed your posts about this issue and I feel there is still hope.
UPDATE:
I WAS ABLE TO RESTORE THE BASEBAND AND NOW THE IMEI IS GENERIC, READS 004999010640000. [/B] I was able to restore nv_data backup from /Efs folder and deleting bad nv_data. Here's what I did:
Using root Explorer in /EFS:
Deleted corrupt files;
nv_data.bin ( 18 April 2015)
nv_data.bin.md5 (18 April 2015)
Renamed backup files (dated 31 Jan 2015) to apply;
.nv_data.bak > nv_data.bin
.nv_data.bak.md5 > nv_data.bin.md5
Using ADB shell:
Code:
adb shell
su
umount /efs
mke2fs /dev/block/mmcblk0p3
mount -w -t ext4 /dev/block/mmcblk0p3 /efs
Reboot
However, the baseband and generic IMEI come&go across reboots and seems not to stick permanently. Any possible steps from here???
NOTE: Previously I have been able to restore Unknown Baseband and Null IMEI in Galaxy S2 i9100 using the above adb method (Code Only) http://www.selftechgenius.com/?p=284

If flashing modem via Odin you MUST turn off the phone then start it in DL mode. Simply doing a 'reboot' into DL mode will not let the modem be flashed.
Note 3 SM-N900 IMEI null Baseband unknown
Android 5.0
Firmware N900XXUEBOE3_N900ODDEBOB2_N900DDUEBOB1 (India)
How did the problem start? – my kid was playing some game in the phone and when I got it back I noticed the problem. It wasn’t because of flashing custom ROM or rooting. It could be due to firmware upgrade as upgrading was set on automatic but not sure.
What all have I done to solve the problem?
1. Rooted the phone and checked EFS folder. The EFS folder did not have .nv_data.bak file. And I don’t have backup of pre-problem EFS folder.
2. Downloaded stock firmware, extracted the modem file (bin) and flashed it, both with odin and cwm. Didn’t help.
3. Downloaded and flashed with odin stock firmware Android 4.4.2 N900XXUENI1_N900ODDENF1_N900DDUENG1_HOME.tar.md5 AND also N900XXUENG1_N900ODDENF1_INU. Didn’t help.
4. With each of the above stock firmware I flashed the following modem files:-
(1) N900_XXUDNA1_MODEM_CWM
(2) N900_XXUENE1_MODEM_CWM
(3) N900_XXUENF2_MODEM_CWM
(4) N900_XXUENG1_MODEM
(5) N900_XXUBMI2_MODEM_CWM
Didn’t work.
5. Used EFS Tool Samsung N7100 900 to back up EFS folder of a working Note 3 SM-N900 and restored the backedup folder to my phone – didn’t work.
6. Tried GSII_Repair app (both with my own EFS folder and my friends EFS folder. – didn’t work.
7. Tried to install xposed to use imei changer app. But xposed did not install as it is not yet compatible with Android SDK version 21 or processor architecture armeabi-v7a.
8. Tried Kies firmware upgrade and initialization, SM-N900 does not support initialization.
9. Tried secret code and got to Service Mode. But service mode is like a blank page of a lined book – no options shown.
10. And I tried factory reset with each of the above firmwares. Did Factory reset and wipe cache partition before flashing new firmware – didn’t work. Then tried it after flashing – didn’t work.
11. Also tried *#197328640# or *#*#197328640#*#* both didn’t work.
12. Tried fix mentioned in - http://forum.xda-developers.com/showthread.php?t=2507403
13. used advice in http://forum.xda-developers.com/showpost.php?p=52408318&postcount=87. now my phone is running Android 4.3 but imei null and baseband version unknown persists.
Can’t afford a new phone. Could somebody please help? And I hate 13 of anything,

As posted by nowy57, need to delete the efs folder in recovery. That's for N9005. For N900 change it to dev/block/mmcblk0p3. You phone has ruined anyway so no harm in trying.

I'll do as you suggest but I have a question. Once I delete dev/block/mmcblk0p3 won't I need to replace it with an uncorrupted file? Doesn't the phone need dev/block/mmcblk0p3 for it to work?
It should be regenerated after reboot, assuming the block has corrupted and unable to write the efs/imei. I'm not sure if it should be the same for N900.
The guide is for old firmware and for N9005. If efs block isn't the issue, it won't work then. It worked for a very few people though. If you have nothing else to try ....
There is also a thread by mirek on solving softbrick/imei issue just a few topics away.
