This basically means you have corrupted the EFS partition of your phone. This can only be fixed in two ways:
1. Like @johntheredimid mentioned, you need to restore the backup (if you took a backup) of your EFS partition before it was corrupted. The method for restore can be found here - http://forum.xda-developers.com/showthread.php?t=2420902
2. If you didn't take a backup, you need to take your phone to a service center and ask them to fix it for you. Would probably have to have your board replaced. So you should install your country's firmware and unroot properly before taking it there. Unrooting methods can be found in the general section.
Looks like this problem is widespread

try flashing your official firmware through Odin. other users solve their imei problem by doing that. see also if you can access engineering mode with that official firmware.

lets wait for others specially those who are expert in android for some advice. I'm just an ordinary security guard so i can't help you much with your problem. what i have suggested you from my previous post was the last thing I did when my phone finally worked. for 4 days i been searching for solution because i also have an IMEI problem. i flash back to official rom, flash patched modem, flash other roms to no avail until such time when my phone doesn't boot because of broken partition :laugh:. if you still have warranty restore it back. if you're already out of warranty and you have money, you can it send it to service center.
P.S.
you can also try this if you have courage. i was able to make some secret codes work but i have'nt tried if it works with engineering mode by modifying hiddenmenu in /efs/carrier/hiddenmenu. use efs explorer to open hiddenmenu and change it to ON.save it and restart your phone and see if engineering mode work. remember that you have to be in official firmware and also rooted to do this. if its not working then you'll just have to wait for a much better solutions from devs.

Please Help: IMEI Changed FIXED!

using Galaxy Tab S t705
IMEI has been changed to 004999010640000/01
what I did:
1. I came from CM12.1
2. I flashed lollipop stock Rom
3. I've noticed that even if it has full signal bar, it shows that "emergency calls only"
4. I checked my IMEI and yes it has been changed
how to restore my IMEI
I got not backup of my Working EFS
That's the default imei when the EFS partition is corrupted or wiped. Its not the first time I've heard this happening with cm 12.1
If you didn't make a backup there's not a lot you can do.
i'm doomed

maybe I should return it to where I bought it
I fixed it!
I remember that I got a backup of a ROM with working IMEI, so basically I just Restored it from TWRP and as a result it has my IMEI back again.
NOTE: ALWAYS BACKUP YOUR EFS/FULL ROM IF YOU ARE GOING TO DO ANYTHING TO YOUR TABLET

IMEI away

Hello I had Protax installed everything ran perfectly. But I installed the stockrom again. But then my IMEI was 0. I installed LineageOS and my IMEI was still 0. So I installed Xposed with an IMEI changer and changed my IMEI. And when I * # 06 # calls is also my right IMEI there. But in the settings my IMEI is 0. I can not make any calls or log in to the network. What can I do?
I think you cant do anything without efs partition backup
hi !
have you tried to flash a firmware with odin ? but with "re-partition" for a full restoration...
Or by a PC ,with smart swift or kies you have a process of restoration after a fail and errors...
i had that issue with my old s2 and a technique in a store got it fixed i gave him the box and he did it

so look likes it just ignores sim card. Try with another sim. Did you buy this phone from a telecom provider? It could happen that the flashing did some damage in the low-level firmware. If it's the case, you'd need the original provider's software. I don't really know if it can be the case with note 5s, but other models had this issue back then.
Without imei, no network will obviously come.
If it at least detects the sim, you can manually flash the imei. After that, it should work provided the phone detects the sims correctly.

If you have the fastboot ROM, then reflash it.
If it doesn't work, then grab another ugglite from someone, install twrp, make a backup of the modem partition.
Then on your broken mobile, make a twrp backup of the modem.
Copy the files from working mobile twrp backup to your twrp backup and replace them.
On recovery, hit restore.

You can flash a qcn file and restore your imei based on your box. Reply to me if the problem still persist, thankyou.

Have the same issue in Mexico when upgrade to MIUI 10, tried some things and nothing works, so i went to my carrier provider, they check my number in their system and everything was fine, so they proceed to change my SIM Card and vuola, network returns and till now, no problems.
It was like the upgrade cause a failure in the Sim Card.
Is the first time something like this happen in my flashing life.
Hope it works for you too.
