Hi,
Thanks for reply . i have done both still IMEI is 000000000000.
Bump
Any help will be highly appriciated
Believe you can't do anything about it, if you don't have an EFS backup, you can't "recover" the IMEI, Serial #, etc. You can probably use this and change the IMEI to a screenshot of your own IMEI, but I am not entirely sure if it works or not.
Hope this might help.

Hi.
I have Note5 at&t and it has Bootloader.
When I was trying to flash another stock at&t firmware, I've lost my IMEI number. As I learned, in order to get back my IMEI, I have to flash my old firmware, but I didn't memorize my old firmware name. And because of the bootloader, there is no way to learn old firmware's name with the root access. I can't root my device. Is there any solution?
Thank y'all in advance.
hi, i have the same problem, tried to downgrade to marshmallow but got an error, i flashed stock AT&T nougat firmware and now have no imei info or baseband info, i have tried flashing n920aucu4eqk6 and n920aucu4eql1 which are the 2 latest firmware versions but still having same problem...help! please
in case this helps anyone, i managed to solve my issue, i downgraded firmware to a 5.1.1 combination firmware, where the baseband and the imei were still being picked up by the phone, then i reflashed the phone with PK1 marshmallow rom (except i did not flash the CP file), only flashing the BL, AP and CSC files and now the phone is running marshmallow and picking up the imei and baseband information and can make calls and send text and picture messages.
thank you

Hello guys,
I have Samsung Note 9 (SM-N960F) and updated to Pie.
I usually use custom ROMs.
Recently after flashing a new custom ROM, I lost IMEI and signal.
To fix the problem, I flashed stock ROM successfully but IMEI is empty (UNKNOWN). There is not network signal.
I have previous custom ROM TWRP Backups. I restored to the old TWRP backups. But still the IMEI is UNKNOWN and no signal.
I had efs backup of a custom ROM as efs.img. I tried to restore it using Partition Backup app and terminal but no success.
I flashed Alexander's ROM (DEV BASE) as indicated in this post:
https://forum.xda-developers.com/galaxy-note-9/help/lost-imei-please-help-t3847336
But still the IMEI and the signal problem is not resolved.
If you have any idea, please help me fix it.
Thanks.

what fine model you have?
anyways flash back full latest stock firmware for your device and ull get back imei.
use frija or samfirm tool to quickly download firmware.
when you flash dled firmware with odin, flash all .md5 files. also flash csc.md5 instead of home_csc.md5
if you fully flash latest October/November firmware as suggested it will work.
if you skip steps or don't use the latest files then it might not work.
once back on stock with signal, follow dr ketans guide for OEM root fix as per his pinned topic in the note 9 general discussion forums.
then flash back a recent custom rom.
suspected cause of your problems:
-modem mismatch with device model
-modem mismatch compaired to rom base
you should always flash/maintain BL and CP manually with Odin and never through rom zips. and always read rom OP regarding modem and bootlaoder.

Thank you for your info.
Currently I have slow internet connection. Anyways, I have started downloading the latest firmware using frija.
I will let you know after flashing the latest firmware when the download completes.
Thank you.
Exact same thing happened to flashing the same rom. Made my sim cards not detect. My phone has been down for a week. Finally have a day of work yesterday and fixed it by flashing stock bl, cp, and csc then flashing back to tgp rom.

Previously, I flashed October update. The flashing process completed successfully but the problem (IMEI & UNKNOWN) was not resolved. I posted the problem is not resolved here.
Then I downloaded another more recent update from another region and flashed and the problem is gone. My phone is full life.
Thank you bober10113. You helped me fix this problem.
