It goes back to # because there is no error backing up /efs to the internal sd-card, /efs folder should be there now.

but the total size of the /efs Folder it creates is hardly 4 MB ???

gday
just bumping this thread as i have the same question..
is the efs folder usually around 4mb? need to know if this backup worked.
thanks.

Compare disk usage for both directories with the 'du' command -
du -s /efs
du -s /mnt/sdcard/efs
Skip the -s if you want to compare each file size. Also, you might want to get superuser access before you do the copy operation (with 'su')
PS: I don't have the phone with me right now, but I assume 'du' is available on the system or as a part of busybox.

[FIXED] $50 : Help me fix \efs to get my IMEI back.

Greeting,
Here's the details.
FIXED....
here's how.
as you may see in the post i stopped in the step of trying to format \efs partation.
but instead.
I went to my friend phone and make this command
Code:
dd if=/dev/block/mmcblk0p1 of=/sdcard/ilostit.dd
this backup the mmcblk0p1 which is \efs to a file.
then move it to my phone \sdcard
and did this commands.
Code:
umount /efs "unmount /efs
dd if=/sdcard/ilostit.dd of=/dev/block/mmcblk0p1 "relfash mmcblk0p1 with the backup.
reboot
this reflash mmcblk0p1 block with the backup,
then copy my \efs backup to \efs.
and no more IO error..
and violaa...
my IMIE is back and the Signal is OK.
Big thank goes to KciNicK who helped me alot and earn it.
_________
The Original Problem :
Tonight I flashed a kernel to my phone, just\ lost the Singal and my phone show no sim card inserted!.
anyway, i figure it out that... the IMEI lost.
in \efs there's no nv_data.bin file!!
So i went to restore the \efs.
but something not right here!
Hope someone can help here.
i tried these commands but no chance tel now!.
here to restore nv_data.bin
Code:
su
# cp /sdcard/nv_data.bin /efs/nv_data.bin
cp /sdcard/nv_data.bin /efs/nv_data.bin
[COLOR="red"]cp: can't stat '/efs/nv_data.bin': Input/output error[/COLOR]
and here to restore \efs
Code:
# busybox tar zxvf /sdcard/efs/efs-backup.tar.gz -C /
busybox tar zxvf /sdcard/efs/efs-backup.tar.gz -C /
efs/
efs/cryptprop_rebootMode
[COLOR="Red"]tar: can't remove old file efs/cryptprop_rebootMode: Read-only file system[/COLOR]
#
Code:
su
# mount -o rw,remount /dev/block/mmcblk0p1 /efs
mount -o rw,remount /dev/block/mmcblk0p1 /efs
# cp /sdcard/nv_data.bin /efs/nv_data.bin
cp /sdcard/nv_data.bin /efs/nv_data.bin
cp: can't stat '/efs/nv_data.bin': Input/output error
tried to flash back to many FWs but no chance,
---
time for some sleep, hope to find something later
the input output error is coz disk full, try deleting/moving some .bak files to sdcard then try the copy again

\efs is read only!, i see members here can you root explorer to delete and move files.
If i can just copy the backup nv_data.bin to \efs that's will be good!.
but i don't know what's to do!.
Can't you use root explorer (don't forget to mount r/w), I find I can get all sorts of errors using adb+cli but root explorer will just do the job.
Another suggestion would be to flash an insecure kernel
copy paste the output of this please...

# busybox cp /sdcard/nv_data.bin /efs/nv_data.bin
also check the free space on the efs partition:

if that fails, it seems that the FS is screwed, try this (with efs mounted as ro, or not mounted at all):

hemmm. i think here's the problem can't stat '/efs/nv_data.bin': Input/output error
all that happened after flashing to the kernel i mention in the OP. ehh.
the ext4 fs on /efs is screwed, try umounting it then format it again, but i don't know if you have the tools to doit, reflashing the efs partition may solve it, feel free to contact me by msn, i sent my address by pm

with odin and a .pit file, you can get the correct .pit from samfirmware

maybe i need step by step, i don't want to break my phone for good
Ok,
unmount \efs
but what's missing to format it?
here's what i got
Code:

umount /efs

Problem Fixed....
Look at the OP for the solution.

Need someone to run an adb command for me

Need a small favor in return for all the help I've given those with kindle fires. I don't have a kindle fire and need some information from someone that does.
Anyone that knows how, I need them to run (if they're using the stock kindle firmware, not cm7):
Code:
adb shell df
Then paste me the results either here or in a PM.
If you're wondering what that information is, it's the partition sizes and disk space of your kindle. I need it for something I am working on that will benefit people that can't restore their device due to excessive noobness
Thanks!

Thanks guys!
If I need anything else, I will ask
Basically, I want to try to automate recovery using fastboot with a graphical app I'm writing in QT (so it'll work on windows, linux and osx). I need to make a system image (system.img), so needed to know what the block size is. That should cut down on a lot of the questions asked.
ty very much

A20e Data Recovery without root?

Hi,
Samsung Galaxy A20e SM-A202F/DS Android 11
My intention is to delete some photos that have been accidentally deleted.
All Windows Trial Applications I tried require root to be able to execute deep scan.
Is it possible to execute deep scan without root?
For example using download or recovery mode or copy the data partition to PC and scan using testdisk?
And if not is it possible to undo root / reset the knox counter?
Thank you in advance.
How to recover a deleted file from /data partition?
I factory reset my rooted Android M phone but now I realize that there was a file in the /data directory which I need. Is it possible to create an image (.img or something similar) of the /data
