After a sleepy ODIN flash, using SPICA ops with G3 firmware => STUPID??? NO, not done yet , next ODIN flash segment, accidentally stick clear phone EFS via Debug options :mad::confused: (DOUBLE CRAZY!!!) NOW i lost the precious IMEI and /efs partitions corrupted as well.

i've got the fixed nv_data.bin and both stl4.img and bml4.img from [email protected] (attached). Thanks for his kindness and supportive to the community!
But even with those i still can't fix the issue!!!! /efs did not mounted via mount command...

as in a GOOD G3, mount command result will be as below:
Code:
rootfs / rootfs rw 0 0
tmpfs /dev tmpfs rw,mode=755 0 0
devpts /dev/pts devpts rw,mode=600 0 0
proc /proc proc rw 0 0
sysfs /sys sysfs rw 0 0
tmpfs /sqlite_stmt_journals tmpfs rw,size=4096k 0 0
/dev/block/stl6 /system rfs rw,vfat,llw,check=no,gid/uid/rwx,iocharset=cp437 0 0
/dev/block/stl7 /data rfs rw,nosuid,nodev,vfat,llw,check=no,gid/uid/rwx,iocharset=cp437 0 0
/dev/block/stl8 /cache rfs rw,nosuid,nodev,vfat,llw,check=no,gid/uid/rwx,iocharset=cp437 0 0
[B]/dev/block/stl4 /efs rfs rw,nosuid,nodev,vfat,llw,check=no,gid/uid/rwx,iocharset=cp437 0 0[/B]
/dev/block//vold/179:1 /sdcard vfat  rw,dirsync,nosuid,nodev,noexec,uid=1000,gid=1015,f   mask=0702,dmask=0602,allow_utime=0020,codepage=cp4   37,iocharset=iso8859-1,shortname=mixed,utf8,errors=remount-ro 0 0
in my case the bold line just missing... so this is must be the problem.

I tried to do the same as SPICA's method as below:
Code:
$su
#dd if=/sdcard/bml4.img of=/dev/block/bml4
#reboot
It's OK then but...
Code:
$su
#dd if=/sdcard/stl4.img of=/dev/block/stl4
/dev/block/stl4: cannot open for write: Invalid agrument
With this error my /efs cannot be mount... and still missing from the mount command. I'm just a linux noob so pls help me out. How can i restore the stl4 partition properly???

My girlfriend now really mad at me due to she don't have her beloved phone this christmas already. OMG!!!!!

and to all rooted i580x user Pls kindly help compare your "good" /efs folder... maybe mine missing something???? due to one time Erase Phone EFS using Odin Debug Options.
Mine /efs now as below:
Code:
/efs/nv_data.bin
/efs/imei/.nvmac.info
/efs/.files/.dm33 (empty folder)
/efs/.files/.dx1 (empty folder)
/efs/.files/.mp301 (empty folder)
And if you can do adb shell, it'll be very kind of you by sharing your good backup stl4 and bml4 - for research purpose (those partitions did not content any of yours personal data - so PLS HELP!!!). Pls do the backup partions as below and share your img here if possible.
Code:
$su
#cat /dev/block/stl4 > /sdcard/efs_dev-block-stl4.img
#cat /dev/block/bml4 > /sdcard/efs_dev-block-bml4.img
TIA and Best Regards

P/S: when do the ls /dev/block/stl* the stl4 is there but cannot restore using the backup img. it's weird...

Code:
#ls /dev/block/stl*
/dev/block/stl1
/dev/block/stl10
/dev/block/stl2
/dev/block/stl3
/dev/block/stl4
/dev/block/stl5
/dev/block/stl6
/dev/block/stl7
/dev/block/stl8
/dev/block/stl9
same for bml4...

I suggest you remove the images.zip
This contains your IMEI, so anyone can clone it.
This zip only bml4.img and stl4.img, the fixed nv_data.bin still inside the phone @ SAMSUNG SC :p. Now they still can not redo IMEI yet so i must find someway else.
