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.

Imei blocked

Hello, I need help, my gtab has blocked the imei, it is possible to change the imei?
Thanks!!!

I think theres an nv_data file in the efs partition that can be edited with a hex editor, but its quite risky, so make sure you research and google everything a lot first. If you've got a backup from superoneclick or something like that, its sometimes possible to restore your imei from that md5's and bin's in the efs partition.

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 is personal if I'm correct , there is no use if someone gave there EFS.

If efs erased. efs be written with the same model. will be the only default imei.

Why would anyone give you their imei number?
Sent from the mighty Note II

write full efs from i9300. restored imei z3x. ALL DONE
