[DEV] SCRIPT MOD inte2ext swap

I am a fresh owner Tf300.
It annoyed me that he sees Tf300 internal memory as sdcard
and as an external Micro SD card.
I searched and znalałem Script of SG3.
Modified it - it works.
But there is a problem.
Micro SD card is mounted as sdcard
but the internal (the old SDcard) will not mount)
Maybe someone can help
Because he wants to improve both were mounted partitions correctly

Trochę Polskiego się tu wkradło
Please change word "znalazłem" to "found"
It works for me after I modified it and install the latest busybox v1.21.0. ( I'm using Energy ROM 4.1.1 btw). Let me know if this works for you.
Here's the script ( I also attach the flashable zip) :
#!/system/bin/sh

mount -o remount,ro /storage/sdcard0
break;
fi

[Q] Need help to execute script to switch internal memory with 64GB card for Note 2

Hi,
I have a Samsung Galaxy Note 2 (SGH-T889). I found a script online which had instruction to execute with script manager (SManager). The file is called app2sdNote2.bin. When I run SManager and located the script, I select Su and Boot. When I select Run, SManager just hangs forever until I kill the process. The grant message never appears. I would like to run the script to use my 64 GB memory card as the default storage. Any help is greatly appreciated.
#!/system/bin/sh
#extsd2internalsd is a modification that allows to switch internal sd to external sd and viceversa. With this you can use default internal sd only for app storage #and the external sd to store all apps resource and all others stuff. The resut is a very big increase of installable apps on gs3

Swap internal sd card with external sd card?

Been searching for a method that works with no luck, tried editing vold.fstab, tried a couple apps from the market but no luck. Im running PAC-MAN 4.3 nightlies with ktoonsez kernel. I have a 32gb SD formatted to ext....can someone help me do this?
Here is my View attachment vold.fstab.zip if you need it.
I had to do that with my Galaxy Ace IIx s7560m. I used kylesrom SD Swap add-on flashable zip thingie.

I'm trying scripts with Smanager...

mount -o bind /data/media /extSdCard
but I get this message mount: mounting /dev/block/vold/179:33 on /sdcard failed: invalid argument

No one knows?
I'm having the same problem with my sandisk 64gb (formatted exfat) since I updated to jellybean.
I never went back to icecream sandwitch to double check though.
The room doesn't seem to make any difference, so it's the kernel.
I was just about to post something similar since I ran out of ideas.

[Q] Make Mount Bind Permanent

Hello People,
I have a question regarding mount bind,
I have one directory on ext-sd that I have mount bind with a directory on sdcard to save space on sdcard with the command,
Code:
mount -o bind /storage/extSdCard/WhatsApp /sdcard/WhatsApp
Now the question is how can I make it permanent as I see it gets unmounted after some time and after a device reboot.
As I see there is no /etc/init.d and I am unsure of how and where to make a start-up script, Searching has been unsuccessful so far
Thanks.

[Q] Tab 3 Kids SM-T2105 SD Card Directory Structure & Moving Apps to SD

While in Kids Mode, my four-year old outsmarted the security software (not hard to do - kid's security sucks. I'm constantly finding him going where he shouldn't) and reformatted the SD card in his SM-T2105 . I managed to restore the files using PhotoRec, but it dumped the files into directories of like file types - i.e. .jpg's, .pdf's, .icn's etc. Would anyone be willing to share their SD card directory structure so I can recreate his as best as I can? I realize each one will be different, but it'll help. I promise to periodically backup the card from now on.
Also, I've found plenty of questions regarding how to move apps to the SD card, but so far have not found any solutions that work. I'm getting the message "Insufficient storage available" and he doesn't even have that many apps installed. He also has a 16G card that is mostly empty. The inability of the Samsung SM-T2105 to move apps to external storage is bewildering considering the pitifully poor space available.
Thanks.

I would like to Bump this I to have a T2105 I do not have the ability to move any apps to SD it is very frustrating.
---------- Post added at 12:43 PM ---------- Previous post was at 12:23 PM ----------
I received the following from generous fellow user @SGTDude about moving apps to sd. I haven't had time to test it, but I thought I would share it with you guys.
Quote:
Repartition the SD card with two primary partitions.
Format the first partition as FAT32.
Format the second partition as EXT4
mount the ext4 partition somewhere
mount -o rw,nosuid,nodev,noatime,discard,journal_checksum,j ournal_async_commit,noauto_da_alloc,data=ordered -t ext4 /dev/block/mmcblk1p2 /system/sd
Copy several folders over from /data
mkdir /system/sd/app
mkdir /system/sd/app-asec
mkdir /system/sd/data
mkdir /system/sd/media
cp -rp /data/app/* /system/sd/app/
cp -rp /data/app-asec/* /system/sd/app-asec/
cp -rp /data/data/* /system/sd/data/
cp -rp /data/media/* /system/sd/media/
add the following lines to /data/local/userinit.sh
mount -o rw,nosuid,nodev,noatime,discard,journal_checksum,j ournal_async_commit,noauto_da_alloc,data=ordered -t ext4 /dev/block/mmcblk1p2 /system/sd
mount -o bind /system/sd/app /data/app
mount -o bind /system/sd/app-asec /data/app-asec
mount -o bind /system/sd/data /data/data
mount -o bind /system/sd/media /data/media
Note: *"/dev/block/mmcblk1p2" is probably right on any SGT3 7" running Kids Rom, but I'd double-check if I were you.

I saw this on http://forum.xda-developers.com/showthread.php?t=2548241 but i really don't know how to do what it ask and no one ever confirms if it works. So I am at a loss. I can't reply because I am a newb.
