Hi
As I know a lot of problems comes from this tiny little but huge monster of the famous nv_data.bin.
Upgrading ... corrupt nv_data.bin!
Costume rom ... corrupt nv_data.bin!
Unlocking ... corrupt nv_data.bin!
Haaaaachu ... corrupt nv_data.bin!
well, they almost solved all the problems that drives from this file for Galaxy S.
What they do:
They have a standard unlocked nv_data.bin file and would use it as a reference to replace the original IMEI, product codes, unlock codes etc.
This is (almost) what "repair_nv_data.zip" will do.
So, we can do it for the Galaxy 3 too.
We can repair our corrupt nv_data.bin files.
What we need:
1. some samples of clean unlocked nv_data.bin.
2. some people who are familiar with HEX.
Dear friends this is already done in this forum for the other Galaxy S phones and this is already done for the I5800 in other forums (samdroid for $20).
I think the first step is to share our nv_data.bin files (both corrupt and intact) to compare them with each other.
Any proposals will be greatly appreciated.
Good luck
P.S.1. Never forget to backup the /efs folder!
P.S.2. This thread is not trying to change anything in original nv_data.bin file (specially IMEI, it's illegal).
Please collaborate, if you can..

Even After Flashing My Device To Another Rom
There Is No Efs Folder

I Hope Someone Help Me Here .... =(
maybe you should look directly thread Recover IMEI http://forum.xda-developers.com/showpost.php?p=17587351&postcount=1
I Dont Have An EFS Folder To Change Nv_data
I Guess I Need An EFS Backup From a Working Phone
Or Full Rom With EFS Package
I Hope Someone Upload EFS Package For Me ...
I Need Help ... The Phone Network Not Working At All
i have the same issue.
the post http://forum.xda-developers.com/showpost.php?p=17587351&postcount=1 only works if you have a backup of the EFS files or if you have the EFS folder.
i dont have any of that. what happends if is use the EFS folder and files from another Galaxy (same model)
I Guess If You Flash Your Phone With Another Phone Efs Backup
You Will Get The Same Imei Of The Phone
But The Phone Maybe Work Good

It will work, but, both phones will have the same IMEI #. That's the reason why no one will share their efs folder (files).

The best way for you guys is to send your phones to the service centers, so they can restore your own original imei numbers.
IF There is a Samsung Service Center In My City
That's Mean I Shouldnt Make This Thread Here ... I Made This Theard To Find A Solution
Anyway Thanks
Somebody Help Meeeee
Fix all 0s imei
My device ( Note 3 N900 ) was showing all 0s Imei after i replaced motherboard. So to fix it I rooted my device, go to root, delete the efs folder and reboot. After the reboot you will see a msg restoring settings.... thats how I got the imei back. Please try it at your own risk.
Guys i made this thread for the people who already encounter this kind of problem and for those who will encounter in the future..
PLS DONT POST YOUR IMEI HERE!!!
We only need those who encounter this error...
1st pks dial *#06# in your phone then your imei number will be popup...
Now this is the problem many of android users has this the same imei.

Hello all, thanks for your time.
I have a quick question that I couldn't find an answer to on these forums or anywhere online. The problem I'm having is making a backup of my /efs file. I attempted to post this in the Q&A sticky post but it wouldn't let me, due to not having enough posts. Anyways, on to the question/problem:
I want to backup my /efs file, but I can't seem to find a way. All the apps I have tried don't recognize my device ( Galaxy Note II SGH i317 ) and EFS Pro either finds an error in mismatching md5s or has an error "accessing archives." I should have backed this up before I rooted and flashed CleanROM 5.0, but as they say, hindsight is 20/20. Anyways, my question is how do I manually copy the file? Most posts I have read hint at this being an option, but a noob like me doesn't even know how to get to the file in the directory. Any help would be greatly appreciated, especially a guide through the directory to the file.
Semi-related question: does a CWM recovery file backup the /efs? I've read conflicting information on this. Thanks again!
Hello~ I have Realmeq. I ran qpst and modify the contents of the efsExplorer, I do not know that it is difficult to correct it again, and some of the changes have been made, so it is not 4g data. If you have a genuine efs or qcnbackup of realmeq, please help me. Or let me know if there is any way to repair the efs.
