Hi, I flashed a custom rom and noticed my imei was unknown, and it says no sim - emergency calls only. I was dumb and didnt make a backup. Is there any way to restore my imei? I tried flashing a different rom and it didnt work.

Try flashing stock filmware with Odin, this has fixed it for me in the past. Just bare in mind that you can't flash older filmware than what is already on the phone so you are probably best to flash the latest.

Hi there,
I'm just wondering why my phone is losing its imei (or rather, its changing to the generic 0049xxx) after flashing the latest MG5 firmwares (I tried three different versions now). I first came from MG1, then flashed the MG9 when it came out. Now, when I flash any other firmware, my imei gets f'ed up.
I havent rooted my phone yet, I'm just flashing firmwares I downloaded from sammobile. Is it just because of this MG5 firmwares not being compatible? Will I still be able to flash newer firmwares when it goes out?
Thanks in advance, cheers!

I have downloaded the August version for the united arab emirates , it seems to see my imei , but whenever i lock the phone (or screen idle closes the display) 90% of times phone freezes and I need to restart it.
it seems that in the latest roms samsung(for S3,S4) change the efs structure ... thats why imei gets mess if you try to change rom after.but if you change the modem with old one it may works....
Gotcha thanks!

who flashed the MG9 firmware had their EFS partition modified.
So in case if you have to go back to earlier firmware you will have problems with IMEI. You have to:
- Restore EFS (that is backed up before this change) or
- Flash MG9 modem which can still read the modified EFS.

Flashing or restoring efs backup doesnt work after flashing mg9.
You need to return to your firmware when you first get your phone out of the box with clean install and wiping everything in cwm before getting into download mode.
Then after flashing the firmware, root then restore efs backup.

so what is new
once you flashed the MG9, the efs partition format has been changed, so if you downgrade (regardless if to the original stock) you must restore the efs partition from the backup you made or just flash MG9 modem.

Guys, If I flash with MG5 firmware and then flash with modem of MG9? Will it work ?
Hello, I was about to take my phone to a service center for check an weird noise, but since I was using CM11 with chinese modem, I decided to flash stock rom.
I'm on the old bootloader, I flashed I9500ZTOBMG1 but when I try to make a call it shows "not registered in network". I checked my imei with *#06# and it shows a generic IMEI starting with 0049...
I have already tried to reflash stock rom via odin, reflash stock modem via odin, restore to last CM backup, but problem still.
I DO have a EFS backup, it's a .tar and a .tar2.gz inside a folder called EFSProBackup, but I don't know how to use it or even how to restore my IMEI. I had already this problem before, but I don't know what I did to resolve. Can someone help me?
Problem solved: I flashed again the chinese modem via cwm after flashing a custom rom, I don't know why, but my imei is back again and working, But I still don't know how to have stock rom working....
Hello developers,
I found the exact same problem posted on xda developers fourm but none of the posts were answered completely or solved.
I rooted my Sm n900 without any problems, installed CWM recovery, installed SuperSu and installed VN Rom for galaxy note 3 (referred this from some Chinese guy on web (since i cant post third party links) its galaxynote3root dot com.
At first i didnt check efs backup option and installed VN rom without any problems (no imei loss or baseband unknown) on my own phone.
But when rooted one of my friends SM n900 with exact same method as i did earlier (but i checked create efs backup this time), i got screwed.
I tried EFS professional, but when i try to put his phone in RMNET + DM + MODEM by pressing *#0808#, and run efs software, and click either qualcommn or efs professional button, it doesnt recognise the device and says not connected.
I tried various other options as well such as rerooting, reinstalling the rom, reinstalling OEM rom, and other roms as well. Every thing is fin except IMEI and baseband null/unknown.
I had a problem like that. On my note 2 .i flashed patition file in odin and it was fixed.

you should bring to the service center to record the IMEI number.
root your device and flash xxuene1 modem from recovery.
Modem is available on xda..search
I did the same and it worked for me
Not worked
A few nights ago, I flashed CM14 with Nougat on my SM-N910C. Unfortunately, ever since the flash finished, my phone stopped reading any SIM cards. The baseband and IMEI both read "unknown" in the settings. Is there any way to return these? I'm okay with anything as long as it ends up making my phone usable again.
I'm not an expert at this, so please explain stuff your help is appreciated, thanks!
Bump! Please help me out!! Any tips appreciated

Did you made efs backup from twrp before flashing rom ?
If you have efs back up then restore it.
If not then Try flash stock 6.0.1 firmware via odin and do factory reset from stock recovery after flash.
