I've searched for 2 days, tried most threads that I can find. I've been flashing roms for a couple of years now, put pulled a rookie mistake and flashed a 7000 rom for my tmo t889 Note 2 and wiped the IMEI in the process. Not cool. Everything else seems to have comeback from the NANROID back up that I created through recovery and I was fortunate enough to run a back up prior to the flash in AROMA so I have the efs.tar.gz back up folder on the internal memory of my phone. Unfortunatly, I cant seem to find a clear cut prcess for restoring the back up. I'm willing to read and learn, but need to be pointed in the right direction for a current fix for this. Please help if you can, I'd love to have my new toy back for our road trip this weekend 
Thanks in advance!!

IMEI restored
I had a similar problem with my SGS3 i9300. I backuped the efs in aroma installer and then flashed omega rom, lost my IMEI (it changed to 004999...), could not connect to my network etc. I restored the IMEI by unraring the efs_29Sep2013-2102.tar.gz to my external sdcard (I got te efs folder). Then I pressed delete on efs folder located in root using root explorer (te efs folder stayed but everything inside it was deleted). Next I copyed the contents of my unrared efs folder from external sdcard to the efs folder in root. I didn't change any permissions, just restarted my phone and IMEI came back and everything worked for me.

I made a backup of efs folder with root explorer just cut and paste on your sd card. Now that I have corrupt files and generic imei and no network when I put the sd files from efs folder when i reboot the phone I find myself the same corrupted files. Is there a way to prevent the system to regenerate files inside the folder efs?

No mate, if you've done a backup which isn't 100% then your knackered. You should always use a toolkit or efsbackup software

As for as I know if your EFS data is lost or corrupt, and you cannot restore a backup version you are stuck. However something has come to mind, does the phone have a Modem listed in the menu where the IMEI is listed? I had a modem not flash right and gave the impression that the IMEI was lost, however upon reflashing the modem, the IMEI returned and the phone as 100% ok.

I had to have my note2 replaced I did a twrp backup placed it on new phone in the backup twrp folder but it is not recognized. Anyone have any possible solutions? Really all I'm after is game data that was backed up,and I'm not sure where to find that particular file in the backup thanks.
pretty sure u wouldnt wanna do a full nandroid restore of your partitions to another device... but as far as your game data goes.... you can use titanium backup to recover the apk and the game data by extracting from the nandroid backup file.
I've tried to do this before. It won't work.

Hey buddy. New device just start fresh. Safest way...
Hey,
I was on the same boat as u. I got it to work. I can remember the specifics at the moment but gist of it is that twrp creates a specific backup folder unique to each device. Open up an file browser and navigate over to where u have your backup. If theyre o. Your sd card it should be TWRP > BACKUPS > (Here u should find 2 folders with a bunch of random letters and numbers)
Those 2 folders are your backup folders. One was from your old device and the other is the folder twrp created for your new device.
When u reeboot into recovery, twrp wont recognize the old backup folder since it was unique to your old phone.
Long story short. Lol. Just go into the old folder from the file browser and copy the backup to the new back up folder.
After that, delete the old backup folder. Your backup should then show up when you boot into recovery.
As for which is the old and which is the new folder. My best bet is tbat the new folder is empty and the old folder has your backup.
Hope that helps.
Let me know if you need more help.
Hello everyone!
Yesterday, I tried to upgrade to a Kit Kat rom. I used the Galaxy nexus toolkit, and did a full backup... plus an EFS backup. Afterwards, I did the full format/wipe from CWM recovery, and installed the ROM.
Well, apparently one of the options wipes your EFS file folder; I have no way of connecting to my network. My IMEI is the stock number, and I've spent hours scouring the internet trying to find a way to restore it. The majority of the responses are "try a factory reset and restore" or "too bad so sad, should've backed up". Well, I did try several options. The first being the EFS restore. Apparently, the backup is stored on the phone and wasn't sent to my computer, like the rest of the normal backups. That option is now out. Oh, how I miss SD storage.
The second was a full restore to stock, again, nothing. Third, I had an old nandroid backup. After doing these I saw that the EFS tree is left untouched, as it is so delicate. The only way to do this is give up and send it in for servicing, or to do a phone NV Backup swap with QPST.
I need to get access to the service menu (or any way to change the USB/Modem) as listed here: http://forum.xda-developers.com/showthread.php?t=1946915
Unfortunately, *#7284# does nothing on an i9250, nor does anything besides *#*#4636#*#*... which isn't what I need. The terminal command doesn't appear to work, either.
I don't understand very well but, have you tried to restore your EFS backup from recovery? Did you make the backup from recovery or from toolkit?

I have done a recovery from the toolkit (as the files are stored on the computer and not the phone) which is where I made the backup from, as well.
However, the EFS partition is apparently never included in this backup, as it is supposed to be immune to changes and formatting. I proved them wrong.
Well I did that same blunder last month with my nexus and then I tried all remedies plus own experiments but couldn't get results. All I heard is that to send phone to service centre. If you find any other solution so do mention here, I gave up after so many tries

@what9000 you may want to check out this thread http://forum.xda-developers.com/showthread.php?t=2508320
Specifically post #6 AND #9
I have personally never used the nexus backup tool, but if it does does backup the /radio folder, you may be in luck.
Well, it has been repaired. Thank you all for your help, in the end I managed to pull some things together in a mash up of fixes.
It appears that upon a new restore from a nandroid backup, I was still getting no signal. However, I did a *#06#, and my IMEI was intact. I read that the Radio folder gets backed up, but not the factory folder. Upon a new install, I imagine the radio folder is wiped, which is why every install from then on had a bunk imei (it had nothing to pull from as my factory folder is toast)
However, it looks like the efs backup I had *did* save the folder structure... I found the efs.tar backup in my galaxy nexus toolkit folder. It had the folder zip, but couldn't restore it due to permissions... didn't feel like messing with that at the moment. I copied them in with root explorer, grabbed the nv_data files from the /radio/ folder, deleted the files from /radio, and restarted. Lo and behold, they were restored from the factory folder with the correct IMEI.
I just put a fresh copy of kit kat 4.4.2 on and have cell service again. Oh happy day, I don't have to use my old HTC Sensation! :highfive:
This also marks the first time a backup actually saved my skin. Usually I vaporize the backup accidentally before it has an opportunity to prove itself useful.
Hi everybody.
I've Installed some days ago a custom rom.
Everything is working fine, but I've seen that my IMEI is changed with generic 00499901064000
even MAC ADRESS is not availlable.
But it seems that everyting is working fine.
Now, I don't rember if I've a EFS backup.
There is a way to rebuild or recover it? (either with that without EFS backup. (I've cell box with IMEI shown)
I've seen that I've a taz file of EFS backup in my SD folder, but it is only 85 byte large.
Thank you very much for help me.
Regards

Bro Goto Your data/radio Folder & Delete nv_data.bin ,nv_data.bin.md5 & Then Goto Factroy Folder & Copy only [ nv_data.bin ] To data/radio Folder & Restart Your Phone Thats it....
Thank you very much.
Solved!
So I found myself wondering how can I make life difficult for myself... I did a software upgrade in Kies on my T805 and now I have a default IMEI...
I was on cm11 before doing the upgrade to 5.0.2
Has this happened to anyone or does anyone have any idea how to fix it?
Many thanks for any reply.
That shouldnt have happened but youre not the first person to state that cm has messed with the partitions. Id stick with stock based roms in future.
Download EFS professional then under the samsung tools tab select other tools then 'Repair NV data from internal file backup'
If youre lucky it will be restored.
Now some friendly advice, ALWAYS make a full backup via recovery before messing with anything custom on your device, especially make sure the EFS partition is backed up.

Thanks for the reply, sadly it restore a different default IMEI ending in /01 instead of /17.
I was 100% sure I had backed-up my efs, turns out I did but on my phone x(.
Any other suggestions?
Try this. Make a backup in recovery of the efs partition.
Boot into android then using a root file explorer open the efs folder then delete nv_data.bin and nv_data.bin.md5 then reboot.
See if this replaces the deleted files with the backup.

You may as well post it as its not a valid imei, it's a generic imei.
Is it 004999010640000?
