I do not see a /efs directory. Is it somewhere else or just hidden? How can I access it? Do I need to somehow mount the partition?

I think during unlocking my phone I confuse the comand umount /efs with unmount /efs and I brick my phone.
So my question is if with a custom kernel is posible to remount again efs partition and make it work again.
Unfortunately odin gaves me errors with my stl5.rfs("EFS" backup) file trying to flash it as EFS.tar renamed to efs.rfs
Thanks for your attention.
If is it posible can anybody make this special kernel to flash it?
Thanks
edit: take note, I am not asking on how to backup.
Having 17 thousand messages, don't want to delete any, of them.
I want messages on my inbox but memory consumed is on sdcard.
On The End 4.0 rom
tried
su
mount -o bind /data/data/com.android.providers.telephony /sdcard/data/sms
I think it's not working.
Any help there experts?
If you want to have a backup then use some SMS backup apps. Else, Titanium FTW.
Btw, what you're trying to do is just mounting. You can mount only images or partition storage in linux. Not a DIRECTORY.
Android uses SQLite database to store anything. If you want to have just a backup and you're sure about location of directory. Just pull with ADB, next time when you flash a ROM, you can use `adb remount` and push those database in same location to restore.

Hello, thank you for replying.
I am very well aware on how to backup. What Im asking is to link, having them on my inbox but memory consumed is sdcard instead of internal memory.
On sgs2, I was able to directory bind (by mounting) on gameloft games by mounting from internal memory to external memory.. I just forgot which commands I used.
Oh well, In that case I understood totally different what you were seeking for. Pardon me.
What you're seeking is "Attaching the filesystems" between directories through mount bind. (But there is not -o in modifiers there for creating such).
First backup your /data/data/com.android.providers.telephony safe place, which you won't be touching until Mount Bind process is successfully achieved.
Please consider I'm not responsible if you loose your 17k sms. Install SMS backup etc. But If you carefully follow these steps, I'm pretty sure nothing is serious.
Now,
1) Make directory in your SDCard, say
/sdcard/data/drigz08.telephony.original.source
2) Use app like root explorer to mount or just fire `adb remount` command if you've set up adb in your PC.
3) Move contents of /data/data/com.android.providers.telephony to /sdcard/data/drigz08.telephony.original.source
So now, all of your telephony directories data are moved. Now here comes the best part...
4) Bind those directories...
mount --bind /sdcard/data/drigz08.telephony.original.source /data/data/com.android.providers.telephony
Click to expand...
Click to collapse
step 4 will bind those directories in a way that from any path same contents are accessible, but new data will be store in sdcard only.
5) In case you want to change the path of source, or unbind directory..
mount -o remount,ro /data/data/com.android.providers.telephony

Let me know how it goes.
PS: I tested all of above under standard linux environment. Working fine.
did not work

Mount bind on new directory doesn't work or still mounted on com.android.....
My situation: Galaxy S3 with latest (26 Oct. 2012) update to 4.1.1 via Kies. Then rooted. Works smoothly. External Sd-card visible, no problem.
Then:
repartitioned SD-card with gparted in Fedora machine: mmcblk1p1 with old contents, mmcblk1p2 for new contents, both vfat. Filled mmcblk1p2 with contents from linux machine.
In the phone the first partition (the one with the old data) is recognised as before. The second partition is not seen.
By using the terminal emulator as super user I can mount the second partition by the command:
mount -rw -t vfat /dev/block/mmcblk1p2 <mountpoint>
<mountpoint> is a directory VISIBLE to File Explorer.
After mounting, however, the directory contents are NOT visible in File explorer (even after stopping and restarting File explorer) but can be listed perfectly in the terminal emulator. Giving the cp-command for copying of an individual (MP3) file from the <mountpoint> to the folder Music shows the copied file in that folder and the music can be played in the usual way through the GUI.
Question:
Does anybody have an idea how to make the mounted 2nd partition visible to the apps so that the files can be accessed though the GUI?
Thanks for thinking about this problem.

Found the solution by some more thinking after all:
mount -rw -t vfat -o umask=0000 /dev/block/mmcblk1p2 <mountpoint>
The -o umask=0000 is essential, otherwise the permissions are rwx------; with the umask option they are rwxrwxrwx and thus can be reached.
For safety sake, mount when needed and umount promptly afterwards.

Dear Bananiel,
your post was closest to the solution of my problem, maybe you could suggest something that will finally help me.
I've partitioned external SDcard with CWM to be used for Link2SD. Link2SD's script works fine and the EXT2 partition mounts well. The problem is with the FAT32 partition which can't be mounted by android (I get "SD card empty of file system damaged" in the notification area). When I go in CWM recovery mode I can mount that partition by choosing "mount USB storage" option and then I can see it on my PC. Partition is healthy and PC has no problems with it.
I've tried issuing commands you've suggested in your post through ADB SHELL, after that when I go to folder that I've designated as mount point I can see files from non-working partitio, but the message in notification area still persist. Also the change is not permanent, after reboot I have to do that again.
Thanks in advance for any help given.

In my situation (SD-card with two partitions, both vfat) the first partition automatically was mounted at start-up, the second needed to be mounted manually whenever I wanted to access it. This was also my intention as that second partition contains sensitive information.
Android has a file fstab.<system-id> in the root directory, in which some mounts are mentioned (but not all).
You could try to edit this file with the permanent mounts you are looking for. I'm not sure if that works, however, as I do not want a permanent mount.
Can you publish your results, please?

Finally!
I managed to get my external partitions visible with the help of this post.
Device: Samsung Galaxy Tab2 10.1
ROM: Candy5_p5110 Android 5.1.1
SDExternal: 2 Partitions; 1st VFAT, 2nd Ext3
Using Mount2Sd from Google Playstore.
I had the same mounting issues. SD external would only mount Partition 1 automatically and manually mounting Partition 2 would only be visible via Terminal.
The solution that finally fixed the invisible 2nd Partition was to reformat the 2nd Partition with Ext3 and allowing Mount2Sd to find it and mount to /sd-ext. Formatting to vfat or ext4 did not work. Only Ext3 did the trick.
I hope this helps others and big thanks to the OP for bringing this issue up.
Hi all,
i'm trying to mount in /data and in /cache 2 partition from my sd.
That is the easy thing.
What happens is that anything I install when I have the 2 partition mounted, after the reboot is gone.
It seems that closing the mobile does not sync and even if I sync from terminal does not work.
Another strange thing is that if I check /data/data directory ( from my sd partition) ls command returns all the files, while
if I use a simple app like es file manager the folder /data/data ( as many others in /data/...) seems to be empty.
Anyone has an idea why this happining and if I could try something to fix this status ?
Thanks for any infos/help...
Hi,
I have a Samsung Galaxy S3 verizon model. Its rooted and running CleanROM 6.0R2 ROM android 4.1.2.
I am trying to accomplish below
1. Mount external sdcard in read-only mode. This is to avoid files on the extsdcard being accidentally deleted.
I have music and some old photos in there. Sometimes my son plays with the phone. I don't want him
to delete all the photos/music on the external sdcard.
I have tried following, but none of then resolved the issue
1. Partition external sd card as ext3 and set all files/dir to read-only permission from ubuntu box.
This didn't work because, phone doesn't recognize the sdcard and partitions on it.
2. Partition extsdcard as vfat and set permission for the files/dir to read-only using root-explorer.
I cannot set permissions for vfat partition.
3. Partition extsdcard as vfat and Mount extsdcard as read-only using "root-explorer".
Doesn't work. Files can be deleted from other apps like Gallery.
4. Partition extsdcard as vfat and mount extsdcard as read-only using terminal and busybox.
This works. But files are owned by root. For group and other, permission is None. Hence
other apps are not able to view the files. I also cannot chmod and change permissions of the files.
It gives "File system is read-only" error.
From reading many posts, I conclude, partition has to be vfat for apps like Gallery/video player etc to view it.
Only option to achieve read-only on a vfat partition is to mount it read-only. Based on this, any idea how I can achieve my objective?
Also, once set, what happens is the phone is rebooted? Anyway to repeat the sets at boot time?
Thanks
