Sorry if this has already been suggested to those that messed up the IMEI during an unlock.
I thought I had lost (or didn't make) my backup nv_data.bin file. But I discovered that days earlier I must have inadvertently backedup that file in sdcard/ProductCodeCheck. Apparently this is from SGS tools?
If others are in the same boat looking for backup nv_data.bin files, try looking there.
Then I removed everything from my efs (with backup) and placed the earlier nv_data.bin file in efs and rebooted. I got back my original IMEI.
Hi,
I've flashed a new ROM, and found that my IMEI is now 004999010640000 (Generic)
I have a backup of my efs folder.
How do I restore it from the backup?
It looks like when I delete the efs folder, the system recreates it automatically...
What's the way to do it?
Thanks
Gil
I fixed this problem and it took me 4 hours to fix it!
Your real IMEI show on under the battery where you see the model phone.
You need to copy the numbers (without the / if u have this) to this website http://www.adamek.biz/md5-generator.php this website make ur imei to md5 .
After you have created the md5 go to efs folder via root explorer and you need to see the file (.nv_data.bak.md5 or nv_data.bak.md5) On this file you see the md5 of the currety copy the md5 u created to the files and close everything and restart ur phone
I already have a working efs backedup
I already have a working efs backed up!
The thing is that when I copy the files from the backup on the efs folder, they get reverted automatically... I don't know what's doing it...
The backup date is older than the current files... this might be the problem...
but how do I make it work?
Is the security and permissions set up correctly on your backup efs?

Did you tried to delete the folder and replace the efs folder backup?
I think you have to copy both the files and the hidden files (starting with a dot) from your backup..
The files with a dot are there to prevent you from accidentally deleting your originals and be left with nothing
The only files I see are:
1) .nv_state
2) bluetooth
3) imei
4) lost+found
5) nv.log
6) nv_data.bin
7) nv_data.bin.md5
Should I choose the file that says: "nv_data.bin.md5"?
If you have backuped your efs folder, this thread can help you:

I think there is a lot of confusion going on around here... so just to be clear...
What file should I have in my efs backup, including the hidden one?
Thanks!
No backup of EFS folder. I believe it was during my attempt to backup that I corrupted the folder.

I have the same situation, same files as posted above, anyone has any idea?
The Baseband problem started when I flashed ICS euphoria from toxic 9.
I tried stock>cm7 initials>ICS passion> euphoria>slim, stock>jetpack the same problem IMEI is 004999010640000 or unknown.
The efs folder contains lost + found folder and unable to delete it. I also tried EFS pro to restore EFS. But nothing works coz the nv_data.bin is used and generated by some process. I will attach the nv log file.
Help !!! I am stuck in froyo (The IMEI NO is correct and the phone works in froyo coz nv_data.bin can be replaced easily)
Solved it by deleting all the files in EFS folder and replacing it with back up files.
The phone should be in flight mode. Then restart the phone.
Hi, i copied my EFS folder to my PC with rood explorer, is this a safe backup, or do i need a backup with a program like it was done with K-Tool on the S3.
If my IMEI gets deleted can i restore it with a simple EFS folder backup, (if so how)
If not, how can i backup the EFS with GT-I9500 XXUBMF8, i tried the touch recovery EFS custom backup, but i kept getting empty folders where the backup was supposed to be copied, (even tho it sayed that the backup was succesfull). Is there another way?
