Hi guys!
My phone - G900K
I really need help.
I am using Revolution Rom before and i don't have problem and then i update it into Marshmallow Stock Rom. I clean wipe (all files using TWRP) and then Flash the MM Stock Rom using Odin. It boots up and the Bootanimation is not samsung, its Olleh G and it has bloatware files. I notice that i don't have signal and in lock screen there is a Emergency Call written down and at the left corner, it's says Limited Service. When i check my IMEI it's all ZERO (000000000000000) 15 Digit.
Here is my Status:
Network - Unknown
Mobile Network Type - Unknown
Service State - Out of Service
Roaming - Not Roaming
Mobile Network State - Disconnected
Phone Number - (My Number)
IMEI - 000000000000000
Bluetooth Adress - Unavailable
I also can't make a call or send and receive messages. I tried flashing Custom Roms and trying to go back to Revolution but it says always that Emergency Calls Only but i have Signals...:crying:. I don't have EFS Backup too.
Please help me. Thanks.

Hello,
I bought my Note 3 mobile and decided to flash C-Rom!
At the morning of one day I flashed the rom successfully. Later I installed all apps I wanted. I have my phone rebooted a lot of times with no problem. Some time at the afternoon of the same day I pick up the phone to stare at it! I activated the LTE option and deactivate it again. This was not the first time of doing it! After that the network signal was missing! I rebooted the phone, but it doesn't ask me for a PIN any more. I used my sim at another phone and it asked for a PIN. I used another SIM at my phone but it didn't ask for a PIN.
After dialing *#06# at Dialer a popup dialog shows up. The title of this dialog is MEID and the content is B0000000!
At settings>About phone>Status> the MEID is full of zeroes but the IMEI seems OK.
At the same screen i see the following:
Network - Searcing for Service
Mobile network type - Unknown
Mobile netwok state - Disconected
Service state - Out of service
My phone number - Unknown
MIN - Unknown
PRL version - Uknown
ICCID - Unknown
Thanks everyone in advance
Very strange.... without doing anything like flashing stock or modem?????

The reason is unknown but it seems like your phone lost a valid IMEI/baseband.
Can you check the Baseband version?
Try to flash the stock firmware, or flash the baseband for your device.
The problem suddenly appeared and that's what makes me feel uncomfortable. The baseband number is N9005XXUENC2. I will try to flash whole firmware, but does anyone know how can I flash only the baseband? I don't want to stay with the original ROM!

Extract modem.bin and NON-HLOS.BIN files from the stock firmware, and flash via Odin.

It is my first Samsung. Could you be more specific? How can I extract those? Can you guide me through?

Do you have the stock firmware file already?

Finally I was able to solve the problem. It is a problem with C-Rom and 4g option. I am going to write a new reply by tomorrow and also to the forum. I appreciate the help guys.
Thanks a lot
The problem is with the LTE activation/deactivation.
I am from Greece with COSMOTE provider. Here, in Greece, at the moment we have to pay an extra fee to the provider in order to have the option of using 4g. The steps as I believe are the following:
1). I am not paying this fee at the moment so I am not able to use 4g.
2). I activate 4g and immediately I deactivated it. I did not want to open it, just touching the selection at the notifications. This option is at the notifications when you slide down the notification bar using 2 fingers.
3). Then the signal goes off and I had to re-flash stock rom once again before flashing the custom rom. The problem has to do only with the signal and everything else works as charm in the C-ROM.
The C-ROM version which has this problem is this C-RoM-KK-v7.1-20140622-hlte.zip

Mobile data was working fine before I tried rooting my phone
I had installed N9005XXUGBOB6_N9005OXXGBOB4_N9005XXUGBOA1 on my phone, Android Lollipop from Note 3 for a few days and decided to root it
However when I rooted it, at first apps were crasing and after that I reflashed the official firmware
After a day I reflashed the twrp 2.8.6.0 recovery on my phone and installed via twrp SuperSU 2.46
Later on I tried to connect to my mobile data. I had enough to connect to my cellular provider but it wouldnt work
Reflashed to stock it still would not work
Called the customer service hotline of my provider and they gave me the settings for my phone as well as APN settings
Still, the mobile internet indicator would not show
On my phone status it displayed:
Service State
Mobile Network Type: Unknown
Voice: in Service/Data: Out of Service
Mobile Network State: Disconnected

Try this, go to setting-about device-untick report diagnostic info.
If the same try install custom rom example cm 12
Reflash modem .
Could be rooted with wrong file .
[ Suposed to do with installing microG Services Core & GsfProxy, FakeGApps from Xposed and MozillaNlpBackend.]
After following steps in this thread here where is not support to get the things back to previous state, my phone [G900M, Resurrection Remix v5.7.4 based on CM13, rooted]. Also I realized that is a threat for S7, but all apps seem to be standard.
Now phone shows the following issues:
1. Cellular Network Not Available... -Network State: Disconnected/ Service State: Voice: Out of Service/ Data: In service. Have data connection, SIM amd operator detected, not able to call or sed/receive sms
2. MAC Address changed to: 02:00:00:00:00:00 Means that something to anybody?
3. IMEI has changed in phone status. Plus there is no phone number
4. Cellular network switch and data switch are linked. That means if I Switch on one, the other is also on, but not possible to switch in different mode
5. LTE discovery app shows: Cell Radio State "connecting". It seems like the phone stucks on this step, not being able to get network
Done: Checked APNs (it doesn't let me add new ones)- are ok, Wiped- nothing change, reinstalled rom- nothing change, flashed model modem- nothing change.
Pending: Downgrade to stock rom (lollipop 5.0)
How can I know the EFS Partition is not affected? Could be that situations a signal of that?
Does a stock rom restore EFS in case of damage?
/efs was not affected, did you resolve the issue?

Hey, I have the same problem, I guess that there's not solution yet.

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.!

IMEI, Network Signal and Baseband is misssing
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..
