Unlocked tab, but failed to backup efs

So I did the tab unlock, but the backup gone wrong.
Know I have a bogus IMEI and can't use market, it just displays a weird one...
Is there any change I can recreat a correct EFS folder to use?
My Tab is form Portugal, TMN.
Thank you

Did you do the unlock by xediting the nv.data.bin file ? If so you should have in your efs folder a nv.data.bak file. Most probably it's a good copy of your nv.data.bin file (look at the file property and check the creation/modify date.....

No, I didnt edit the file, I downloaded the repair_nv filea exchaged it.
Also, hen I open my efs backup the tar file is empy, it show no files...
Can you sugest any file manager for it?
Or can you tell me the adb command to try and restore that backup?
thanx

You need to have root access in order to see the content of the efs folder. Rootexplorer is an excellent tool, well worth the price.

How can I restore IMEI from backup?

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.

EFS Restore

Guys how can i restore and efs folder?
I have an efs.tar file with all the files, how do i restore it? each time I try on recovery it says that the folder is empty or that the file is not there...
edit: and there is any way to conver a tar file to img?

must back up your efs on stock rom?

I just rooted my brand new note3 but I forgot to backup my EFS before flashing X-note... Now I made a backup on X-note rom, is it still ok for restore if I ever lost my EFS? Thank you

As long as you have the EFS file then it should be OK, keep it seperated from your internal HD if possible also!
EDIT: Btw the EFS file is around 14MB or so -

darn,.. my backup only 408KBs. I use this method http://forum.xda-developers.com/showthread.php?t=2447342 result said Everything is OK..
any idea why my file is so small?
from my root explorer ... the efs folder only 1.4MB big
OH! when i decompressed the file, there is disk image file is around 14MB
how do i restore it? btw.... I throw this compressed winrar file into ODIN? or decompress first, and then select these individual files accordingly

Sounds like it's OK.
Restoring I'm not so sure, due to me not having done it myself, I know you need busybox installed though or you'll encounter problems. Be warned EFS cause be a major ballache to do from people I've seen trying to restore, some have no issues though.
