go to terminal and:
df
see if your /system/sd/ device is being used. Did you make all the symlinks?
mine is being used but also the phone memory is decreasing also. help?
thx i think im not sure...checked out that i have my app to sd thx
I'm having the same problem. I did all the steps on this tutorial from maximus but when I d/l an app my intermal memory decreases and my sd memory remains the same. I went to terminal and wrote df and I don't know what to look for lol I did see system/sd or something like that though. But I'm not sure what that means. Sorry for being such a noob, I'm new to this
Same prob here fellas....
I followed the instructions for the Hyk apps to sd wiki tutorial.
when I check my sd card, it shows the apps
cd /system/sd/app
ls
and I can see that the /system/sd has 25MB used which sounds ok but at the same time, I only have 35MB left on the phone, it was 48 yesterday and all I've done is install apk files via my computer using adb install command.
Why is my internal memory going down and how can i fix it.
To answer my own question.
I think we also need to move dalvik-cache... though not really that important, it's nice to keep the 70-71mb free.
I moved the cache and it went from 35MB to 70MB free.
Keep in mind that moving your apps to sd does not move your cache for default programs. I noticed my memory dropping and realized that it was my browser, maps, market, etc cache. I followed some tutorials on here to move those and my memory hasn't been dropping anymore!
there are three directories that get increased when u install an app
/data/app - stores the apk file
/data/data - stores cache and databases that the app uses
/data/dalvik- app cache used by the system
if u move only one of the above directories ur internal space will still decline
su
cd /data
ls -l
this way you can see if its linked correctly- should show the app folders linked...

Thanks for this! How can I tell which caches I have linked?

Well, some of you may have heard my ramblings around here that I've been working with some of the devs here(JF and MartinFick deserve major praise, probably more than me) on getting a better way to do the whole apps to sd thing.
After 3 days of talking/discussing/working on it, I've finally reached the fruits of that investigation and thought I'd share. This new method uses the filesystem unionfs to essentially meld the /data directory with the /system/sd directory, so that they appear to be one. This has the potential to allow users to move specific apps to or from the sd card, is far more stable than the normal symlink method(will still boot, etc even if there's no SD card) and should be easier to set up. Now, onto the tutorial of setting this up.
BIG DISCLAIMER NOTE: This is a major hack of the phone and it is fully possible that it will break your phone(I've seen no permanently bricked phones but that doesn't make it impossible). Use this method, and my app along with it at your own risk.
REQUIREMENTS:
1: This only works on JF(possibly only on 1.5, not sure about the others) and The Dude's v.1.0 or greater. The Dude's 1.0 or greater actually does the steps in this tutorial for you so you can just run appstosd2 and set it all up from there if you're using his ROM.
2: This still requires you to have 2 partitions set up, first FAT32 and second ext2. Although you can use the appstosd2 app attached to this post and available in the market for $0.99 which will partition the card for you.
3: If you want your apps to go to the sd card, you must have a directory "/system/sd/app" If you didn't have apps to sd before on the ext2 partition do the following in terminal emulator or run my appstosd2 app after finishing the tutorial:
Code:
su
mkdir /system/sd/app
If you want the private-apps, or dalvik-cache moved you can replace "app" in that code with ""app-private", or "dalvik-cache" respectively. Do not copy "data" to the sd card. My script will delete it on the next reboot.
-----------------------------------------------------------------------------------------------------------------------------------------------------------------
Alright, first there's some files you need.
1: init.rc in .zip attached to this thread
2: a2sd.sh in .zip attached to this thread
All the above listed files should be put on your sd card(my tutorial will assume they are in the root directory of the sdcard(the topmost folder)
-----------------------------------------------------------------------------------------------------------------------------------------------------------------
If you need to undo the normal apps to SD first do the following in the recovery terminal(it's not strictly necessary but I'd recommend it):
Code:
mount data
rm /data/app
mkdir /data/app
if you moved the dalvik cache, repeat steps 2-3 with "dalvik-cache" instead of app. Ditto with "data" for the data cache.
-----------------------------------------------------------------------------------------------------------------------------------------------------------------
Then go to terminal emulator and type the following:
Code:
su
cp /sdcard/init.rc /data/
cp /sdcard/a2sd.sh /data/
Then reboot and you're set. By default all future apps are installed to the sd card. In order to move an app to the internal memory do the following in terminal emulator:
Code:
su
cp /system/sd/app/[the app you want to move] /system/intmem/app/
rm /system/sd/app/[the app you want to move]
I will be incorporating this into my appstosd app soon(probably as a JF and TheDude-only version until the rest of the devs get on board).
I have included a copy of appstosd 2, which will copy all apps from internal memory to the sd card with an option to remove them from the internal memory. This will only work if you have followed this tutorial.
If you don't have partitions set up, appstosd2 will now do that for you with user-set partition sizes.
NOTE: If you're using The Dude's ROM and find yourself with an outdated version of this since he doesn't always update his ROMs at the same time I update this, do the following in terminal emulator to update(after putting a2sd.sh from the attached a2sd.zip on your sdcard):
Code:
su
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
rm /system/bin/a2sd.sh
cp /sdcard/a2sd.sh /system/bin/
reboot
For JF1.5, do the following to update:
Code:
su
rm /system/intmem/a2sd.sh
rm /system/intmem/init.rc
cp /sdcard/a2sd.sh /system/intmem/
cp /sdcard/init.rc /system/intmem/
reboot
NOTE FOR UPDATERS: If you had your data on the sdcard(/system/sd/data), it WILL GET DELETED with the new version. This is a necessity in order to get both wallpaper and protected apps working. I recommend moving it back to the phone.
EDIT: And here's another tutorial from ThatsBS(might be easier for the less tech savvy to follow?):
I am still learning a lot everyday from this forum. So for people new to this process let me noobify it, if I can, as I am one too.
Start by reading the first page!! Get all the stuff you need from page 1. (apps2sd2.zip and a2sd.zip )
I started from a fresh wipe and flash of jf1.51 adp.
A newly formatted fat32, non partitioned sd.
Put the init.rc and app2sd.sh on the sd (the files NOT the zip)
Then go to the terminal emulator and typed:
su
cp /sdcard/init.rc /data/
cp /sdcard/a2sd.sh /data/
Then reboot
Next I ran the apps2sd 2 app. It will ask you how much to you want to partition. I did 3000mb the first successful time and the dreaded low mem notice would not leave the status bar. I have read not to make it more then 1500mb. Have a good connection, dont force close it. It will reboot.
Next, after the reboot, I ran the apps2sd 2 app again and pressed "copy apps to sd" (let it do its thing)
Reboot.
Next I went back to the emulator and typed:
su
mkdir /system/sd/app-private
mkdir /system/sd/dalvik-cache
Reboot.
Go back to the apps2sd 2 app and hit move dalvik-cache.
Reboot for good measure and your done.
I did this in about 10 mins. Worked flawlessly.
I have a ?, if i have been using your app what dod i do diferent or what should i change?
Thanks
Good job, thanks!

JF1.5 build has already unionfs.ko in it, doesn't it? Is there any difference between this unionfs.ko and the one included?
1. I hear unionfs is not really stable at this point, is it true?
2. Why do you want to move the whole /data folder to sd, instead of just /data/app, /data/app-private?
3. You might want to add a command to remove previous app2sd changes (i.e. delete symlinks, create folders.)
4. How do you put selected apps to internal memory after this? Copying to /data will copy to sd card again.
The whole idea is really interesting! Thank you for your work!

You don't have to do anything different. It will find all the apps you put on the sd card. If you want to set the phone back to normal(so the phone memory apps can still be there), you can do the following in the recovery terminal:
Code:
mount data
rm /data/app
rm /data/dalvik-cache (only if you moved the dalvik-cache)
mkdir /data/app
mkdir /data/dalvik-cache
@Dimath: yes, I did mean SD card, good catch
1:JF didn't mention it and from a little bit of using it, it seems stable to me. Plus, no matter how much I've screwed up, I haven't managed to boot loop my phone yet.
2: You could just mount those independently. I might end up doing that eventually but for now the way it is works for reasons I'll get to.
3: True, although it's not strictly necessary. If apps2sd already works, this won't break it. I'll put in a guide on undoing the symlink method
4: Actually, no. My script sets the internal memory as the main file system in the union, so apps automatically go there. Moving apps to the sd card just involves copying them to /system/sd.
Ok, just a little confusing.
I didn't use the apps2sd to move apps over to my SD card. What I did was set it with the busybox ls command. I guess that's the symlink.
My question is, if I didn't use apps2sd, can I still use your method? I also moved the dalvik cache also, everything works fine for me now, my apps go directly to the SD card when installing since my memory stays at around 65 MB no matter what I do.
Just need some laymen terms to help me understand that if I'm NOT using apps2sd, and I just linked them with the recovery method, what's my pitfalls / advantages?
Thanks.

Yes, any other method of apps to sd currently uses the same symlink method, so following the directions as if you installed my app will work. A note though is that all future apps will install to the internal memory by default. I did that because it's MUCH easier to move apps from the memory to the sd card than vice versa. You can use the code I posted if you want it the other way around.
would this also work for /data/data and app-private?
or is this particular setup only for dalvik-cache and app?
oh and before I do this, just wondering, so in theory, since I have a 1.5GB ext2 partition, my free memory will be 1.573GB (1.5GB + 73Mb internal)? The internal memory will just run down and switch over to the sdcard when needed (but be seen as one filesystem)?

This works for the whole /data folder and everything under it. Everything is automatically installed to the phone memory right now so you can just move over anything you don't want on it(will be making an app to do this automatically)
EDIT: oh and anything you already moved over to the sd card will still show up.
Code:
su
mount -o remount,rw /dev/block/mtdblock3 /system
cp /sdcard/unionfs.ko /system/
cp /sdcard/init.rc /data/
cp /runme.sh /data/
cp /sdcard/a2sd.sh /data/
I see, when I run these lines of code (I can do this from adb also right using adb remount) this IS the new symlink method. It's just all at one time without me having to manually link anything.
Right?

Wrong, no symlinks here. Pure unionfs goodness. Basically it convinces the operating system that /data and /system/sd are the same thing. So anything that's on /system/sd shows up under /data but everything that's normally under /data is still there. Think of it like what happens in windows when you merge folders with the same name, but in this case in actuality everything stays exactly where it was.
New news: If you haven't seen it, I updated this tutorial(and the scripts with it) quite a bit and would now consider it to be completely fully functional.
Also The Dude will be sending me an advance copy of his next ROM tomorrow to verify it works. In his build the apps to sd will be automatic, with no user setup(although if you want apps on the sd card you'll have to make an app directory under /system/sd(mkdir /system/sd/app), ditto for dalvik-cache and data).
Finally, I will attempt to add this into my apps to sd app tonight, thus rounding out everything I can do.
After all this, the only thing left is for Haykuro to build it into his ROM and me to make an app to move specific apps to/from the sd card automatically.
This will no doubt be the method of choice in no time. Great work. Sticky?
If anyone dl'd the latest version(that fixed the race condition, etc), please download the one I just put up. I made that one in windows and I believe the funky carraige return(that indicates a new line) that windows uses screwed it up
So I got some kind of error, and I don't know what is going on.
I put in all the lines in the terminal emulator app..
but after line cp /runme.sh /data/ it gives me an error
it says "cp: cannot stat '/runme.sh': No such file or directory
Any help? I rooted my phone just so I could run my apps off of my SD card.. and now I can't figure out how to get it to work. Somebody help me please.

Ok, I am going to re-partition my memory card.. and then re flash to JF1.5 and try it again.
Just tried it, one issue I'm seeing is android seems to install [email protected]@[email protected] into /system/intmem/dalvik-cache at boot. Is there anyway to have that only in my dalvik-cache on the sdcard?
Its a fairly large file at 3megs so I want it to reside solely on the sdcard and even if I delete it from intmem, whenever I reboot it gets added again.
Now when I display the internal phone storage from the settings menu, it shows up at 835 megs.
I wonder if this is possible to use unionfs and make an ext2 fs object as a file on the FAT fs. That way no 2nd partition is necessary. Plus, if you remove the sdcard, everything will still work.
Maybe we could combine unionfs and this method that uses an ext2 image on the fat32 for apps to sd.

I've been looking at that possibility with JF and MartinFick as well, seems like it could be a good plan but I wanted to get this bit done first. It's a good point about the dalvik-cache, but in order to fix it JF(in this case) would have to change /init.rc to make sure to do this bit before building the dalvik-cache.
Can't download apps from market
hmm so I didn't hit any errors when doing this, but afterwards I am unable to download any apps from the market. It just continually says "Starting Download..." Everything else seems to work well.
I had this same issue when I tried to manually setup apps to sd using the symbolic links. I narrowed the issue down and figured out this only occurred after I moved the dalvik-cache over to the sd card. I'm assuming I'm doing something wrong, but can't seem to figure it out. Any pointers in a general direction would be most helpful
I'm using JFv1.50 ADP1.5, not the modded version by LucidREM. For some reason the bootloader couldn't pickup his version on my phone and --edit-- I'm pretty sure I have the SD card partitioned correctly... everything else seemed to work ok. The ext2 partition shows up as the correct size
*EDIT* So apparently my issue was the SD card as well. Just did a format of the sd card and it fixed it. I also formatted data and cache (alt+w in recovery mode). Thanks MarcusMaximus!

If I have apps2SD and the dalvik-cache both moved on the dudes builds already, do I still have to create those directories or will my existing setup still work fine? I would like to know what kind of issues I may run into when the dude releases .95 with this (hopefully, not getting my hopes up just in case).
I'm just curious, i'm pretty sure everything went well for me as for apps2sd... but i was wondering what is the 100% official no bs way to know if you have all your apps on your sd card along with the cache and it's no longer on your internal memory? i mean i only have 33 apps installed but i only have 67mb free on internal memory... i cleared my browser cache along with my market cache and only have 67mb free... any idea anyone?
i just cleared my faebook cache in app management and it jumped to 69mb free. so i'm taking it that my apps are on my sd card but my cache isnt? how do i go about doing this without messing everything up? any idea anyone please?
i forgot to mention...
8GB SDHC SanDisk Ultra Class 6
Rooted JF v1.5
33 Apps 69MB Free
Overclocked @ 528Mhz (Max) 384Mhz (Min)
AppsToSd (At least i think lol)
Well if you want to make sure the sym links are there, the best way i know is to connect the phone to your pc
adb remount
adb shell
cd /data/app
cd ..
ls
if you end up in /system/sd directory then you know its a sym link.
on another note as for the free space, the cache is held in the /data/data directory. I have the below folders moved to sd and have prob around 70+ apps installed and have 73 meg free. FYI also i remember reading somewhere that when you move folders off to the sd partition, nand does not back them up because nand does a bit for bit read of the flash chip on the phone and since that data is no longer on the flash it isnt backed up. Just something to think about if you want this info backed up.
/data/app
/data/app-private
/data/dalvik-cache
/data/data
Furthermore, if you move your cache to sd, put a symlink in and clear cache afterwards it will delete that symlink. You don't need to clear your caches after moving them, you should do it before they are moved.
Good luck.

just type
su
ls -l data
if you see app -> /system/sd/app
then you know you linked up correctly
same would go for any other linked directory
app-private -> /system/sd/app-private
dalvik-cache -> /system/sd/dalvik-cache
etc.

i think i messed everything up now... lol i followed somebodies instructions and all my apps werent working anymore, so i go to install them again but the market says they're installed already, so i uninstalled and tried to reinstall n now everytime it downloads and tries to reinstall my phone reboots... argh i didn't think it was gonna be soo complicated to get apps and cache working off of my sdcard.
There is a space between cd and ..
Cd<space>..
Sym link means symbolic links. Think of it as a shortcut that exists inside the folder. so when you type in cd /data/app u r accually going into /system/sd/data

that is the files and folders in that directory, think of it as the same as doing a "dir" command in windows. But from the output you got /data/app is setup correctly to go to the sd card.
Ok.. I hate to tell you this but... may be you're better off just do it all over again.
Wipe, install clean copy of JF 1.5, wipe again, run apps2sd application by MarcussMaximus, delete cache folders on SD and then move your caches to sd manually from terminal emulator
I found a really good set of directions here
Make sure you understand though how it's done before attempting.
And the best way to tell is to note how much free space is on your phone after clean install, after moving everything and after using your phone for a few days.
Good luck.
Terminal emulator.
su
cd /data/app

i pretty much did, i used the lucidrem jf 1.5 and it went soo smoothly, im running about 50+ apps and got 73mb of internal memory free, and i checked that site u linked in ur post, thats a great tutorial site on moving certain cache.
I want to move my ringtones and notfication sounds from internal storage to /sd-ext. To do this I need to create a symbolic link from /system/media/audio -> /sd-ext/media/audio/
It seems that root explorer is unable to create symbolic links so are there any other android apps available that can do this? I really don't want to have to install the android SDK just to do this so is there an easy way to do this from the phone?
Cheers,
Richard.
If your rooted and have terminal installed you should be able to enter the following:
ln -sf /sd-ext/media/audio /system/media/audio
I haven't tried it myself in android but its what would work in a regular linux environment.

Thanks that did the trick. I installed Terminal Emulator from the market and su'd then created the link. After a reboot all my ringtones and notifications are now working from my sd-ext partition

Glad to hear it worked, at the time I replied I didn't even own an Android phone yet.
This weekend I finally picked up a Desire HD.
I am trying to do the same thing on an elocity a7 ... rooted, running froyo, Dexter's mod 1.42. Terminal has su. I enter the following:
Ln -sf /sdcard/sdcard-disk/olivetree /sdcard/olivetree
I get the message: Link failed. No such file or directory.
Both directories exist and contain files. I have tried with various combinations of directories existing with or without files ... same thing.
Any ideas? Thanks

Assuming /sdcard/sdcard-disk/olivetree and /sdcard/olivetree are both directories without any functioning links and contain some files that differ from each other, I would do enter the following in the terminal:
cp -a /sdcard/olivetree /sdcard/sdcard-disk/olivetree
rm -rf /sdcard/olivetree
ln -sf /sdcard/sdcard-disk/olivetree /sdcard/olivetree
These steps copy all data from one directory to the other.
Delete one of the directories.
Link the existing directory to the removed directories location.
Thanks, Technoplunk. Now I get the message:
Link failed. Operation not permitted. :|
Does your lines in the terminal begin with a hash "#" character? If it does not then your not running the commands as root.
Try typing 'su' without the quotes then running the commands I suggested above.
Yes, I was already running in root ... did the su ... got the #
Thinking a little harder about your problem I realize your trying to do a soft link from one portion of a fat32 partition to another. I suspect the issue might be that you can't create soft links on a fat32 partition as it probably isn't supported. Microsoft created fat32 and never supported soft links on it.
It worked for laxity because he was linking from an ext3 or ext4 partition to the fat32. The actual link resided on the ext partition.
The file structure of this tablet seems a bit weird to me. /sdcard is the tablet's internal storage. The sub-directory /sdcard/sdcard-disk is the micro sd card. I would have expected it to be in the root directory of the tablet, but it's not. However, I didn't think the internal storage was FAT32. Is it??
I'm baffled.
The "mount" command will list all partitions and their types. Its a bit verbose on my phone. Any fat32 partitions will probably say vfat rather than ext(#).
Aha. Several partitions (/system /data /misc /cache) are ext3.
/sdcard and /sdcard/sdcard-disk are FAT32.
Is there a way to format the internal /sdcard as ext3?
Thanks so much for your help!
I recommend poking the people in the Elocity A7 section of the forums, they have more experience with your particular device and can likely tell you if it is safe to try or not.
I should also add that changing those partitions to ext3 would mean you could no longer drag and drop files from a Windows pc as Windows can't read that partition type.

It seems that root explorer is unable to create symbolic links so are there any other android apps available that can do this?

I don't mind if it's free or paid application!
Problem solved!!!
Root Explorer v2.17 (estimated releasing date tomorrow, 10/28/2011) has "Link to this folder" / "Link to this file" and "Create link" options!
No more painful usage of terminal emulators on small screens!
Thank you Speed Software !
I have a similar problem. The music bib stored by google music should reside on my second sd card. In the moment the app stores the music automatically on the first internal sd card. But I have the same problem that the internal sd card is fat32. So is there any solution to move my bib to the second sd card?
Thanks
Hi there!
I have a similar situation as I got deleted my "lib" file, that is a symbolic link, from my "com.android.mms" folder.
From RootExplorer I remember the file pointing to "... -> com.android.mms", so what am I supposed to type in Terminal Emulator?
Tnx in advance.

Assuming /sdcard/sdcard-disk/olivetree and /sdcard/olivetree are both directories without any functioning links and contain some files that differ from each other, I would do enter the following in the terminal:cp -a /sdcard/olivetree /sdcard/sdcard-disk/olivetree
rm -rf /sdcard/olivetree
ln -sf /sdcard/sdcard-disk/olivetree /sdcard/olivetreeThese steps copy all data from one directory to the other.
Delete one of the directories.
Link the existing directory to the removed directories location.

On my daughter's SGJ5 running 6.0.1, I have an issue with Musical.ly taking too much space because it is storing video files on the phone memory and wont be moved to SD card.
So I got inspiration from your post and thought of creating a symbolic link between the folder where Musical.ly stores its videos to another one on the SD card: respectively '/storage/emulated/0/Android/data/com.zhiliaoapp.musically/files/localvideos' on the phone memory and '/storage/6561-3337/Videos/musically' which I created on the SD card.
I ran the following command using adbputty:
cp -a /storage/emulated/0/Android/data/com.zhiliaoapp.musically/files/localvideos /storage/6561-3337/Videos/musically
rm -rf /storage/emulated/0/Android/data/com.zhiliaoapp.musically/files/localvideos
ln -sf /storage/6561-3337/Videos/musically/localvideos /storage/emulated/0/Android/data/com.zhiliaoapp.musically/files/localvideos
cp and rm worked fine but when I try to run the ln command I get the following error:
ln: cannot create symbolic link from '/storage/6561-3337/Videos/musically/localvideos' to '/storage/emulated/0/Android/data/com.zhiliaoapp.musically/files /localvideos': Operation not permitted
Edit: I tried the following command instead (inspired from "https://forum.xda-developers.com/showpost.php?p=62273638&postcount=18")
ln -sf /storage/6561-3337/Videos/musically/localvideos /data/media/0/Android/data/com.zhiliaoapp.musically/files
and that works for creating the symlink but Musical.ly does show anymore Private videos, nor is it possible to create new ones.
Could you please help me with this?
Cheers
Using on CM11, should work for any android build above 4.#.#
If you are having trouble mounting folders like I did like SuperMount, FolderMount didn't work for me
Even if they work, they require payment for most important features
Get BusyBox (Most custom ROMs already have it, like CM)
I used busybox mount because regular mount didn't work
Get the SManager app
Move the contents of obb folder to somewhere in external SD, (Or you can move the entire obb folder and create an empty obb folder in sdcard/Android)
Create new script from SManager (or any other text editor and save it with .sh extension) and type the mount command in it
Lets say I moved the folders inside obb to storage/sdcard1/obbfolders, then command is:
busybox mount -o bind /storage/sdcard1/obbfolders/ storage/sdcard0/Android/obb
Save the file (in SManager you press back after typing and it asks if you want to save)
Click on the file you created and check the Su and Boot boxes and Save
Script should be good to go, click Run
I use FX File Explorer to verify it (obbfolders should be shown on the main page)
Reason I created this thread, I searched this for a quite good amount of time and couldn't find anything
All "mount folder android", "mount bind android" searches either come up dead or show me an app that doesn't work for me

Trying to follow your guide....can't get it to work ?
1: Moved the entire OBB folder to my SD
2: Installed busybox, started it, software says it is installed, there's a button to install again....don't know what else it does ? If I click install, well, it installs again
3: Created the new script, saved it, ran it. It seems OK
4: When I open FX File explorer, I don't know what I'm looking for, I don't see anything going on, no operations running ?
...I didn't want to delete the original OBB directory since I don't have confirmation of this working ?
Thanks for your help
almost there...
Hi there
Had the same problem and found your thread after quite some surfing. Following your instructions, all seemed to work fine, just had to inject an "su" before the busybox mount command, then the whole external_sd (/storage/sdcard1/) was mounted to an existing (empty) folder on the internal sd (/storage/emulated/legacy/External_SD)... at least that's how it looks in SManager. When checking the target folder via file explorer, it still looks empty.
My setup:
- Samsung S4 mini on Cyanogenmod 10.2
- phone is not fully rooted, but root is granted to SManager and Busybox
- external sd card has permissions "d---rwxr-x" and is owned by "system" whereas the internal storage has permissions "drwxrwxr-x" and is owned by "root"
do I face a permission issue?
If yes, how to solve that (tried to change permissions of the External_SD folder recursively using chmod -R under root... but didn't suceed)
If not, any ideas...???
Thanks for any hint!
cheers
I'm using Lucky Patcher to bind oob folder, you should try.
@needo2: Is it required to mount the folder? This could cause problems on rejecting sd card. Maybe it does work replaceing the source directory with a simple link ("ln -s") to sd?
