Magic DEVICE Imei and Baseband restored but sim card DIE
You have to reflash a GB-Rom,i.e. JVU. Then everything will be ok. And after that flash a ICS-Rom which not makes disappear the IMEI and then, without wiping you may flash this special ICS-Rom which caused that issue. Now everything should be ok. That was the experience I have made.

Did you ever make a nandroid backup using TWRP? You can restore the modem and EFS from it. From the sound of it, the data in one or both of those folders is either corrupted or erased.
As above or restore your backed up EFS folder .
Worth trying a factory reset first .

Hello everyone, it's the first time starting a thread and asking questions in Grand 2 Q&A section.
I am running a unmodified Motion ROM V17.0 on my Grand 2 SM-G7105. The Rom has been operated for 2 months and I didn't faced any sort of problems.
Unfortunately, yesterday when I turned on the device, it gives me a wrong date and time. Just when I am checking what caused this problem, I found NO mobile singal and Wifi singal! I can't make calls, receiving SMS and surf the net. The IMEI number is Null and Baseband version turns unknown! I thought something must have been corrupted and I wiped the cache, dalvik cache and data in TWRP recovery. When the phone booted up again, Start up wizard popup and there's many FCs. I reinstalled the Motion ROM with full wipe in TWRP. The phone boots up but however, it cannot recognize the SIM card. The baseband version and IMEI are still 'unknown' in the Settings App. The phone will lag to death if I didn't turned on the Airplane Mode. The phone has random reboots and cannot be shut down. But the Wifi worked now. I think the mobile singal problem still persistent is because of the IMEI and baseband unknown...
I want to repair my phone and make things works again like before. Is there any ways to restore the IMEI and Baseband version? I've seen a few articles about this and they mentioned EFS folder is damaged. I wanted to flash a stock rom via Odin but no computer is with me now.
Please help me!
Any help is highly appreciated! Thank you!

today i flashed the xxx rom and flashed the ap file via odin all went well and device was working but i suddenly realized my network was gone.under phone info the baseband was unavailable and my imei was gone.after alot of searching i found a site where a efs+nvdata.tar file was uploaded.i flashed that file and i got my imei and baseband back but mobile networks is still unavailable. ......when ever i boot up the phone it shows a unlock sim message........i tried kies,efs professional but nothing works.i tried to restore the efs.tar.gz file but it isnt working.i noted that my imei after flashing the file matched my phone,but the s/n number doesnt match but i dont think it matters as long as the imei is ok.PLEASE HELP ME,if a efs backup will fix it i beg anyone to send me a backup or tell me how to fix it..please:crying::crying:

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..
