Hi.
I have flashed my ROM to Ml4 4.3 and flashed Phliz recovery and after my ROM did not work with some apps I decided to flash to custom ROM though recovery. Unfortunately after installing ROM my Imei and my baseband turned to unknown. I don't have any backup of efs folder too. I flashed all the ROMs and modems but no use. What should I do?
custom rom 4.1.2
I had the same issue when I first got my Note 2, and resolved it using EFS Professional:

Some questions here...
I have just rooted my stock DMF2 rom and got efs backup. Then i flashed the latest perseus kernel.
I wanna flash the latest omega rom but i read somewhere that if i flash a non DMF2/ME6 based rom, i will get a imei error.
Is there anyway i can flash omega rom without getting an imei error?
Thanks for helping and sorry for my english.

well try it yourself since you have a backup.
Make sure that also have a backup of your Modem and Build, (found in settings under Baseband (modem) and Build Number).
because your EFS backup would work 100% if both of these were the same when you're restoring.
If things didn't go on well, then you can reflash the ROM.
in case the backup wouldn't work (works once then no signal on next restart), then what you have to do is as follows:
1-Flash the ROM that has the same build number as the one you had when you backed up your EFS
2-Restore your EFS and restart
3-Restart again, if there's no signal, then restore your EFS again and restart once.
4-Downgrade your Baseband to any version (I prefer DME4).
5-Perform an OTA update (OTA works if you had status normal and an IMEI and phone signal, so you need your EFS to be restored and the signal working, for the status normal you need 0 flash counts and Full Wipe of data through VolUp+Home+Power).
6-If you have ROOT, then don't touch Install or Install all! click on later.
7-Get Odin Mobile Pro (you need the Pro Version). and run it.
8-Click on "OTA/ update.zip". point it to "/Cache/Fota(might find random numbers here)/update.zip". In case you can't find the file, just use Root Explorer, and copy the update.zip to anywhere on the SdCard0 or extSdCard, and Point Odin to it.
9-Check the EveRoot Option and Odin Pro.
10-Flash the ROM.
now you'll have the same build number, but your baseband is now updated correctly. Just restore the EFS one more time and restart and it should work.
Note: If you may tell me your current baseband and buildnumber, I could save you time by giving you my files if I have the same as you.

Bump, I'd like to know this also.
As title states, i lost my IMEI/carrier signal after flashing the latest nightly (2-27), and haven't been able to get it back
I tried to inject my imei backup, but using the *#7482# to enter qualcomm usb settings hasn't worked, not sure why (maybe it was changed in kk?)
I tried flashing a modem, but i can't find the appropriate kitkat one for my phone. the only one i found was for jellybean.
Any ideas guys?
I can't seem to get any dialer codes to work
If you are on ATT Flash d2att instead of d2lte

There is no KK modem because there is no official KK ROM.
Try flashing the latest AT&T modem.
If flashing modem doesnt work. You need to restore back to stock then make sure everything works. Reboot back to recovery and do a backup of your rom and EFS. I use Philz recovery. After you make ur back up go ahead and flash custom rom.
If you did backup your EFS in recovery. Just reboot back to recovery and just restore only the EFS. Save you from reflashing back to stock.
Hey guys. I installed cyanogenmod 11 yesterday on my note 2. i ran into some problems. There was no service, imei and baseband fields were blank. i couldn't dial the *#After countless afters searching xda i managed to fix it by reverting back to the stock Samsung firmware (4.3).
My question is how do i install cyanogenmod 11 and also get network service now that i have my imei and base-band back. I'm not familiar with efs backing up or what to do with it to get network service working on a customer rom.
Any help is appreciated. thanks

To do that you must be rooted and have a custom recovery.
Download and Install PHILZ recovery latest version.
Make Nandroid backup using recovery. Keep it somewhere safe.
Download doctor Ketan's Multitool zip file and install it via recovery.
Now you will see Aroma window with various options. Chose EFS BACKUP.
Exit Multitool and restart the phone.
Copy EFS backup from internal memory card to Phone (approximately 20mb size)
Now Flash any rom u like.
Press thumps up if you found this suggestion helpful.

Hello other solution is to use TWRP recovery , when you do a bakup whis this recovery you can choose what you want to keep : EFS, data, system etc... and where int SdCard or extSdCard.
I hope this can help you.

My friend had the same problem..he has a efs backup but both of us dont knw how to restore it back (tried few methods post googling but none worked even after saying successful)
Unbelievable how many of us fell into the same trap. I also flashed this recovery because I wasn't paying enough attention to what I downloaded. And I also lost my IMEI. I hope you backed up your EFS or you could be in trouble.
If you backed up your EFS then just recover it with the same program that you used to make the backup. If that doesn't work try flashing the stock Samsung ROM and try again. You can also try to flash the modem. This helps sometimes.
I had a backup of my EFS. I tried to restore it in CM12, didn't work. I tried to restore it in Ditto4, didn't work. Then I used an old STOCK Samsung ROM. First I got a generic IMEI whereas I got null/null on custom ROMs before. Making progress. Then I tired to recover my IMEI eith EFS. Didn't work. Then I flash the modem with modem_XXDME4__ (i'm from central Europe) and voila, IMEI back.
This is of course all possible only if you backed up your EFS file. If you did not, chances of getting the phone back are quite slim. I've read about a hunderd threads while trying to recover my phone and some say that when you don't have a backup of your EFS partition, just flashing your stock Samsung rom might work. By stock Samsung ROM I mean the one that was preloaded when you bought your phone.
Good luck.

As what @Sheeptar (Thanks ) said, you can try to restore the efs using the method you used to back it up.
Else, try flashing a stock rom. This happened to me too and I was in the middle of flashing a new rom, so I flashed a stock rom using odin, and didn't have a problem while using the new rom.
I guess that version has no modem support, trying flashing previous version
thanks a lot guys ...
had a full twrp back and restored same ....
u ppl are so supportive ....keep up d good work ..
lolz i restored d full backup
didnt tried only efs...
another possible way..
This worked for me once.. Restore the stock version. E.g. Verizon. Then use the setup/phone/reset to factory option. I flashed the wrong note 2 room onto my i605 . Restoring via twerp didn't work, but the above did.
This is killing me.
I have the LG D852 v20j from Koodo/Telus in Canada stock 5.0.1
I bumped and rooted and installed TWRP 3.0.1 (unofficial)
I then backed up everything via TWRP (including EFS)
I also followed the manual method here to generate two .img files for EFS backup:
http://forum.xda-developers.com/lg-g3/development/efs-lg-g3-efs-backup-restore-t2907329
I upgraded to a stock based MM ROM:
http://forum.xda-developers.com/lg-g3/development/canadian-d852-stock-bumped-rooted-rom-t3056843
IMEI was still there
I flashed the MM Videotron Modem he provided and I lost my IMEI number
Flashing the TELUS MM Modem doesn't work either
To restore it I have tried:
1- Restoring from TWRP the EFS alone
2- Reflashing the Dene ROM
3- Restoring EFS via manual method (works sucessfully but still "Unknown" IMEI)
4- Completely restoring via TWRP and even then trying the manual method
So, I have two backups (manual method and TWRP) and I still cannot restore my IMEI and get on any network.
I thought backups were foolproof.
What do I do?
I just had to flash an old LP BELL modem on the MM ROM and it worked. No need to restore efs partition.
see here for solution:
http://forum.xda-developers.com/lg-...rooted-rom-t3056843/post66184123#post66184123
try flashing the MM stock rom you flashed and check if the IMEI is there. if it is, your best bet is to - from within that rom - go back to stock kdz/tot method and hopefully you get it back, you can then restore your backup with IMEI intact. this is what fixed my "unknown" IMEI from this exact situation except different model. another thing you can try before the kdz/tot method is to flash the MM rom and then restore your backup but do not reboot your device, after you restore your backup, flash the appropriate bootstack then you can reboot.
Ok, so the issue is resolved.
I just had to flash a working LP (BELL in this case worked) modem
