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.

Flashing stock not helping at all,i tried various method but the issue is not resolved. The imei need to be there. I read some issue been resolved with octoplus and Z3x which mean need to buy the tools. Terminal enumerator also not working.been 5 days trying to solve this problem.

N7100 IMEI changed to 0049 after flashed CM12.1

Hi guys, my n7100 IMEI changed to 0049XXXXX after I flashed CM12.1 from stock 4.4.2(France, but i forgot which version.) and I found that my N7100 cant recognize my sim so I flashed the stock 4.4.2 (form HK.) IMEI still missing.
I haven't backup my EFS. Is my phone dead? what can I do to get back my IMEI?
UPDATE: I got this on my main screen, is my phone dead?

thanks for ur answer
that xqcn file didn't work it wasn't the right one
I flashed it anyway and it bricked my phone I fixed that after restoring an EFS backup I took from the internet but it does just fix the EFS doesnt retore the IMEI
the only QCN that worked for me is the one in attachment but it has 1 IMEI for the 2nd sim I cant correct the one for the 1st sim, I tried all the QCN I could find in the internet 1 that one worked

(You can open the QCN with 7z)
compare the one that is working with other that have 2IMEI and see the differance and try to edit with a hex editor, if you can't then your best bet is 4pda

same for the folder EFS_Dir in the same directories
and the size is not the same but I dont' know how that would help

What board version do u have ? I lost my imei too when unbricking with Test point via edl
I couldn't restore my imei can u tell me your Telegram so I can ask you some questions tjnx

Try searching for these terms on google. "deadboot repair" "edl" "firehose". Usually after flashing a deadboot repair package the imei resets by reading the chipset. Goodluck.

the board version is 1.2.9 nicobar I solved the issue partially I have my 2 cards working fine and can make calls didn't check the 4G yet
I can give u all the QCN I used but before do a EFS backup if the QCN brick your phone u can restore the EFS from recovery and the phone will boot normally.
I don't have a telegram sorry

To my knowledge the imei value is stored/burned in the soc on all snapdragon chips. I am not sure why it did not auto regenerate after an edl flash.
