Well you can start by saying what exactly did you do. And secondly I would suggest you check with a phone technician who can fix up your imei partition. I wouldnt suggest going to the Samsung service center as they might actually void your warranty all together if they find out you rooted your device, its risky and not worth it.
Lost my phone a Galaxy Note II N7105 LTE i need to locate the IMEI as I dont have the box/plus didnt write down the IMEI. I thought from Play Store under devices they could display my IMEI as want to report it to network operator to Block/Bar that phone
I did howver once backup the EFS partition maybe anyone know how to extract IMEI from that ? or any other way maybe from a common cloud service perhaps people use and they could have my IMEI in there?
Don't you have imei under Your battery?

I recently entered the world of rooting and roms etc and yesterday i tried to flash DN3 ROM V5 for my AT&T note 2 GT-N7100.
The flash went smoothly but after the intial set up of the rom i realised I had no mobile service, so I then checked my imei using *#06# and my imei was found to be Null/Null.
I know that this has something to do with the efs folder in my phone but i don't know how to get mobile data back on my phone.
i have an efs back up SAMSUNG-SGH-1317_20141009_213525.tar i just dont know how to restore it.
PLEASE HELP
The correct international rom would be 7105. So you need to return to the stock rom and modem to fix your phone.

The real question is do you have an i317 or a n7100? Those are two different model numbers and you would need the n7105 version of dn3 for i317, The n7100 rom is not compatible and does not have lte support (hence the no baseband problem). Odin back to stock using the correct firmware, then you can re-root and flash stuff. Just be vigilant and make sure you have the correct files for your device before you flash them.

Before doing anything you should backup EFS. Unfortunately, EFS is unique and can't be replaced by any other.
If you have a corrupt EFS folder on your SD card, try the procedure in the link given below
http://forum.samdroid.net/f38/guide-recover-your-imei-9-steps-vaskodogamagmail-xda-6008/
If this does not work out for you, don't get into whirlpool of flashing this and that.
Send it to service center with Original bill and IMEI.

Hello dear XDA users!
First of all I would like to give offer to one that will solve my problem, I will send him 30 EUR directly to his PayPal account.
I am Note 7 Lover as I am collector of these phones.
I have many succesful Note 7 phones recovered from death updates which were fully discharged.
But I did great mistake which I can´t live with.
I had one Note 7 , fully functioning with all connectivities. I managed to install HydraRom and Hydrakernel there on my own as I did it many times before. I am an idiot I didn´t make backup of the system and mainy EFS in working state.
I broke display a little on my primary Note 7 so I needed to recover my TWRP backup on another phone but I accidentally checked restore also EFS partion from my previous phone.
So the phone just turned on and No service, Baseband unknown. My great mistake.
Tried lots of original ROM restore, reflashing HydraRom or radios/kernels, nothing works.
I read a lot about what i did, I have no backup of EFS partion from the one that has problem. I have only Samsung Box with only IMEI written on it, back cover is changed so there is no IMEI or S/N.
I googled a lot, tried all the programs (Z3x, Chimera, Octopus) but none of them has capability to write IMEI directly to the this N930F phone.
I finally found a software called SAMFIX V1.3 and after clicking Baseband in the HydraRom phone menu is visible
The phone is able to look for carriers (but only one) but had NULL IMEI.
Wifi and Bluetooth works well, but there is no IMEI when i dial *#06# and imei is 0000000000. And Bonus is that the phone acts as Dual SIM, through it is only N930F single SIM. So the phone menu in HydraRom after dialing says 0000 for both IMEIs.
I tried to write IMEI with software IMEI changer via xposed, but it "writes" it only for the system instance.
Phone is still unable to find my carrier of connect to one.
When i tried to see device info with all softwares it says:
PDA Version: N930FXXU2BPJ8
Baseband Version: N930FXXU2BPI5
CSC Version: N930FOXM2BPI5
Please help me to restore EFS somehow, or at least to succesfully write IMEI and S/N (which i don´t really have) to phone and can connect to my network as before my idiosm I did with restoring ROM from "same" but different device.
Who will help me will get 30EUR from me (student) on his PayPal.
Did you tried stock firmware? If not flash N930FXXU3BPL2, and do wipe. https://forum.xda-developers.com/note-7/help/n930fxxu3bpl2-t3520988/page2
Hello!
I tried flashing oficial firmware, didn´t solve my problem, or something called COMBINATION Factory binary but this failed.
Radio and baseband is all OK, I have two other phones exactly with this firmwares and versions and they work all OK.
Problem is with EFS and CERT, before wrongly restoring this partion with TWRP backup from another NOTE 7 SM-N930F the phone worked all OK.
I managed to do with many softwares to write IMEI and S/N and it succeeded!
It is written in CERT file and not only with some IMEI changer for system run instance. It is readable via ADB.
Phone can unlock the SIM card but is unable to load carriers.
I read a lot of this problem and I compared CERT file of a backuped one and CERT on the restored one after my IMEI repair.
The CERT on the recovered one has it´s own IMEI now but has same ImeiSign,PubKey,PubKeySign as the backuped one from what I made restoration with TWRP.
So these codes are OK for the IMEI and S/N on the working one but they are inconert for the not working one because of encrypting.
I tried to flash CERT from the working one to bricked one but this does not work because of some CPID encrypting or so.
Have you please any solution to
1. Fully restore working EFS on the phone to work as before?
2. Try to make calculation for the right ImeiSign,PubKey,PubKeySign for that IMEI?
