Dear Fellows,
After a bad upgrade in a SGS I9000b, my phone does not recognize your own imei (bad efs).
I had made a backup of my EFS using only RootExplorer, and now I can´t change files permissions.
My system uses /dev/block/stl3 to mount /efs
I cannot change /efs (not have permissions to change when its mounted and if I umount folder, changes aren´t saved).
I need a solution to make a new stl3 using my efs backup to be used on ODIN.
It is possible to build a new efs using my data (imei number, bluetooth mac, etc,etc) of Samsung Galaxy I9000b?
Thanks for any help.

Hi.
I've made a terrible mistake on the /efs partition. I have nandroid backups, but none of them contains the /efs partition I think(if it contains, that would be the best way to fix it, pls tell me).
So, I'd like to mount my /efs to PC, and try to recover the manuelly deleted nv_data.jpc file, which could be my saviour.
Is it possible? If it is, please help me out telling me how.
Solved, but not by mounting it. I managed to recver the nv_data.bin from the corrupted .bak of it.
Hi please someone help upload nv_data.bin or /efs backup.
/efs partition was corrupt can not recover without this file
Unfortunately, doing such things are illegal, because technically you would using another person's IMEI.

I used also TWRP for backup my efs and it show 0MB too but it did backup the efs. My backup took ~150KB.
By the way, the IMEI is NOT saved in efs partition. That what you think is IMEI, is really only a security key code for access IMEI (in /efs > imei). The real IMEI is saved in an another partition but i don't know where.
I think the security key code in your /efs > imei folder is wrong.

Somehow the EFS partition on my P5WIFI got damaged and everything was lost. Is it possible someone has a dump of the files stored in there? The loss of the data in this partition causes strange problems with the stock Android.....
I managed to recreate some amount of the EFS partition by using "EFS Professional". The Wifi MAC is incorrect (looks like a generic one) but hey whatever.

You have got a Wifi Tab , and Wifi Tab does nt have got a EFS Partion.
I think you need a PIT file.
Normaly if you flash a Stock Rom this will restore a EFS Partion in Phones.
On the WiFi tablets, the EFS partition stores unique data like your WiFi MAC address.
I'm not sure what happened to this tablet. It was my mother's until last week. Somehow it wiped itself. All of her data was gone. It seems as if something caused the tablet to wipe the data partition, and that the EFS partition was also damaged. The EFS partition was not mountable in recovery and errors were displayed. Nothing actually formats EFS though, including PIT, so I had to go in with ADB shell and format it myself.
But without the EFS data, strange things happen like the stock ROM will go into factory mode. It puts a "factory mode" icon on the homescreen, the lockscreen and power menus don't work, and the initial setup wizard is never shown. Fortunately "EFS Professional" has a function that recreates various files within the EFS partition and this restores normal functionality.
