Default [Q] EFS directory lost after flashing from Stock 2.3.6 to CM10.2

Hi,

I have the Galaxy Player 4.0 YP-G1

I followed the description on this thread :
http://forum.xda-developers.com/show....php?t=2386992

But unfortunatly, after flash, my efs directory was empty (only "lost+found" directory inside)

I search in the forum and find that it was better to flash from 2.3.6 to CM9 and after CM10.2, so too late for me !!

I found also that I should simply copy my backup of efs directory to /efs so I do this :

adb shell
su
umount /efs
mount -o remount,rw rootfs /
cd /sdcard/backup/efs
cp -r * /efs
dd if=/sdcard/backup/efs.rfs of=/dev/block/mmcblk0p1
mount -o remount,ro rootfs /

The files were successfully copied but when I reboot, the directory /efs was again empty !!!


Of course, I make some backup :
Nandroid backup of my 2.3.6 before flash to CM10.2
backup of efs directory in /sdcard/backup/efs/ (automatically when I flash CM10.2)
backup of efs directory in a file efs.rfs (when I was on 2.3.6)

What do you recommand me to recover my efs directory ?
Restore my nandroid backup 2.3.6

Re-flash to 2.3.6 with Odin according to this thread (is my efs directory will be regenerated ?):

Or other things ?

Thank you very much for your precious help !
I like this forum, very helpful
