I am not 100 percent sure, but I see no reason to mess with the bootloaders. Flash the new ROM with Clear EFS checked, and I THINK it will restore your IMEI. It has done so with others.
At this point, you have nothing to lose by trying.

do not clear your efs without making a backup of your efs first.

Just flash the rom from your carrier (www.samfirmware.com) that the phone came with, and you should have proper iemi.

His efs is already fragged...so silly to back it up. He is trying to restore it.

Don't clear your EFS. You might still have the backup files in there. If you open your efs in root explorer or an adb shell and have .bak files you need to delete the nv_data.bin and nv_data.bin.md5 files, reboot the phone and it should recreate the files from the backups.

Flash CM7. It's been reported to regenerate IMEI, but ONLY if you keep on using CM7 or MIUI. Any attempt to go back to stock will remove the IMEI.

It does not sound like is efs is totally fragged from his original post. Backing up /efs is easy -- after clearing efs there is no way to regenerate the nv_data.bin (that I know of) without a backup.

Good luck, though the consensus of I am sure smarter types than I seems to be that you should take a copy of your efs folder before doing anything...and that seems wise to me, just in case.

Quick Question about Flashing

I've managed to mess up my Infuse because I'm an idiot and I forgot to back up the efs folder.
Now that I have this phone, I've successfully rooted it but I searched everywhere for the efs folder and I can't find it.
Is the efs folder unique to samsung? I've tried searching for an answer but I couldn't find any.
Thanks!

I can't say whether it is unique to Samsung or not, but I've never seen anything about one on the D3.

Bad EFS Partition(I lose my IMEI)

I ask your help please I'm desperate!
I have a captivate-i897 which by mistake you delete the contents (with root explorer) to the EFS partition, which it is made ​​without losing the IMEI and put a generic, I can not make calls or sms.
If you can help me just ask you with this tool http://forum.xda-developers.com/show...php?p=18524176
make a backup of your EFS and passes it to me, to see if achievement fix.
Please make the backup in .tar format.
I really need your help, thanks
Sorry for my bad English

Loading someone else's efs folder will only get you the same generic IMEI.

As weird as this may sound, flash Mosaic 9. I've had bad EFS setups twice in the last 2 weeks, and both times have been able to get back to normal by flashing that ROM.
I think it may have something to do with zombies understanding how to handle undead phones... or something.

[SOLVED] Restore IMEI with absolute NO backup?

Edit: Solved by going back to Stock GB. Thanks everyone!
I've got a friend who got a new Captivate from the US. And he flashed CM10 right after getting it, without making a backup of the efs folder. Now, the efs partition is completely empty, and of course it says "Unknown baseband, unknown imei", etc".
I've looked around, but all the imei restore methods seem to require at least one efs file. However in this case we have none. So, is there any way to restore the efs/imei? Maybe mounting it to the pc and running a file restoration software (might sound desperate, but we are).
Also, I have another captivate (this one is mine) with the efs. Would it be possible to modify my backup to use his original imei and then restore it in his phone?
Any ideas are welcome. Thanks in advance.

Installing CM should automatically backup /efs to the sdcard. Look for a folder called "backup." Also, flashing to stock can sometimes resolve these issues without tampering with /efs

I can't give you a 100% guarantee, but the two phones that I've had to recover IMEI's for both regained the efs folder contents when I flashed to stock GB from an ICS or JB rom.

Waiting 5mins inbetween postings sux.
The easiest way I could find to restore my IMEI was to re-flash back to a stock (in my case it was a rogers rom) then go forth from there. Like it was mentioned above, CM9/10 save the efs and restore it after flash. I lost my IMEI while flashing Helly and was frustrated at reading the "fixes". It was just easier to format, reflash stock then go back to CM10 (Which I'm running now and it's great).

Thanks for the replies.
Apparently, he tried to flash CM9, and in the process he thinks the internal memory (/sdcard/) was somehow wiped and now he can't find that folder. I told him to use recuva or something like that to try and get them back, let's see how that goes.
But in case he can't recover that folder, is there any other way? Maybe mounting efs partition on the memory and using recuva then?
He really has bad luck...

Well, there really is NO backup. I can't find the efs backup on the sdcard. Even tried with Recuva and there's nothing there.
What's funny about it is that there's no files in the efs partition, yet the df command says it's full. Any ideas?
As a last resource thing, I was thinking about using the efs from MY captivate and see what happens. Thoughts?
I really apreciate any comment!! Thanks in advance.

http://forum.xda-developers.com/showthread.php?t=1300843 Go there and get one of the One-Clicks that will take you to stock GB. As several other people have said that is your best bet for getting the efs folder back.

Just do a search on xda, there are losts of threads than can help you work through this.

I was able to restore my IMEI using this method:
http://forum.xda-developers.com/showthread.php?t=1264021
I did it via the terminal emulator on the phone.
I didn't have a good backup of my original /efs folder, either.

it just happened, that my solution for restoring imei on sgs3 i9300 came by installing Android Revolution HD rom. Maybe it happened because it's based on stock. You should try, maybe it will help. :good:

you should ALWAYS start from there with any android phone(not that, but something like that). i started from there...now i see posts on forum about guys that have problems with IMEI or phone won't boot cause EFS partition is damage(or something)...
after that just READ CAREFULLY when doing something...read the tutorial until you fully understand it... and have patience...don't hurry things.

EFS / IMEI losts are uncommon on brands other than Samsung. But i agree, BACKUP EVS AND NV.
Second, if you're not on 4.3 official, DO NOT UPDATE TO IT via official methods. You'll get knoxxed.
