[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) :

[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.

#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

[GUIDE] Make Link2SD use a disk image instead of a second ext2 partition

Was using Link2SD to move apps to the second partition of a micro SD card for the usual reasons... Then did -something- that broke the micro SD card slot. Now what to do?
Possible solutions:
Is it possible to repartition the internal NAND? -- Wouldn't that involve unpacking and repacking the kernel image? Better not... Although it was an inexpensive tablet, it would be an expensive brick.
Is it possible to bind-mount a directory on the "internal SD" for use with Link2SD? -- Would that even work with vfat? (Permissions and stuff...)
What about replacing the ext2 SD-card partition with a disk image
Materials:
Android tablet. (Broken SD card slot optional.)
Root with busybox installed.
Link2SD installed and configured -- This has to be done prior to breaking the SD card slot. Link2SD's startup scripts are needed, which it may not create without a "properly" formatted and installed SD card.
Computer with Linux installed OR a Linux Live DVD -- To create the disk image and transfer the contents from the physical SD card to the image file. I used Ubuntu.
USB transfer cable (optional) -- To transfer the disk image from the computer to the tablet. Also to execute terminal commands on the tablet. Possible to do over a network, but the cable can be faster and more convenient.
Do not try this unless you are fully prepared to brick your device.​
Method:
Create the disk image on the computer:
Code:
qemu-img create -f raw link2sd-disk.img 3G
Format the disk image to ext2:
Code:
mkfs.ext2 link2sd-disk.img
Mount the disk image to a newly created directory:
Code:
mkdir /tmp/link2sd-disk
sudo mount -o loop link2sd-disk.img /tmp/link2sd-disk
Mount the original SD card with the second ext2 partition.
Copy the contents of the sd card to the disk image. Use rsync to keep file permissions and other metadata. The trailing "/" on the directory names is important.
Code:
sudo -s
rsync --archive --hard-links /media/path-to-sd-card/ /tmp/link2sd-disk/
Unmount the sd card and disk image.
Code:
sudo umount /tmp/link2sd-disk
Transfer the disk image to your tablet.
Code:
adb push link2sd-disk.img /mnt/sdcard/link2sd-disk.img
Edit /system/bin/debuggerd on the tablet:
Code:
adb pull /system/bin/debuggerd
Edit debuggerd with your favorite text editor. Pay careful attention to the actual identity of the internal sd card as used on your tablet (/dev/block/mtdblock9). Notice that "busybox mount" is used. The normal mount command does not support the necessary options.
Code:
#!/system/bin/sh
#added by link2sd
LOG=/data/link2sd-debuggerd.log
ls -la /dev/block/ 1>>$LOG 2>>$LOG
echo 1>>$LOG 2>>$LOG
echo "$(date) mounting..." > $LOG
busybox mount -t vfat -o rw,relatime,uid=1000,gid=1015,fmask=0002,dmask=0002,shortname=mixed,errors=remount-ro /dev/block/mtdblock9 /mnt/sdcard 1>>$LOG 2>>$LOG
busybox mount -t ext2 -o loop,rw /mnt/sdcard/link2sd.img /data/sdext2 1>>$LOG 2>>$LOG
echo 1>>$LOG 2>>$LOG
mount >> $LOG
echo 1>>$LOG 2>>$LOG
echo debuggerd.bin launched >> $LOG
exec /system/bin/debuggerd.bin
Backup the original file and transfer the new file and set permissions.
Code:
adb shell mv /system/bin/debuggerd /system/bin/debuggerd.001
adb push debuggerd /system/bin/debuggerd
adb shell chmod 755 /system/bin/debuggerd
All done. Reboot. :fingers-crossed:
Hope the above is useful or enlightening. Let me know if I need to explain anything in greater detail.

I've tested this on HTC One X and it does not work. After mounting sdcard and my image using these commands:
Code:
busybox mount -t vfat -o rw,relatime,uid=1000,gid=1015,fmask=0002,dmask=0002,shortname=mixed,errors=remount-ro dev/block/vold/179:14 /mnt/sdcard 1>>$LOG 2>>$LOG
busybox mount -t ext2 -o loop,rw /mnt/sdcard/link2sd.img /data/sdext2 1>>$LOG 2>>$LOG
I have access to the image file from /data/sdext2 but my sdcard is not visible in the system (but it is mounted in the /mnt/sdcard). Does anyone know how to mount .img during boot? Binding to debuggerd seems to be not the best option. :S
EDIT BELOW:
I've found a solution to this issue:
1. create 03mountsd file
2. put it in the /etc/init.d/ directory (for example, using adb)
3. reboot
03mountsd contents:
Code:
#!/system/bin/sh
#added by link2sd
LOG=/data/mountsd.log
COUNTER=60
ls -la /dev/block/ 1>>$LOG 2>>$LOG
echo 1>>$LOG 2>>$LOG
echo "$(date) mounting..." > $LOG
while [[ $COUNTER -gt 0 && ! -f /storage/sdcard0/app.img ]]; do
COUNTER=$(($COUNTER-1))
sleep 1
done
echo "=> COUNTER = $COUNTER" > $LOG
# busybox mount -t vfat -o rw,relatime,uid=1000,gid=1015,fmask=0002,dmask=0002,shortname=mixed,errors=remount-ro /dev/block/vold/179:14 /mnt/.sd 1>>$LOG 2>>$LOG
busybox mount -t ext4 -o loop,rw /storage/sdcard0/app.img /data/sdext2 1>>$LOG 2>>$LOG
echo 1>>$LOG 2>>$LOG
mount >> $LOG
echo 1>>$LOG 2>>$LOG
EDIT: still not working: applications moved using link2sd and this method are not visible for android. :/

[Q] Internal/External Memory Swap

So, I have a Sprint Galaxy S3 Running Cyanogenmod 10.2.1, and I'd like to trick it into thinking my 64GB SdCard is the Internal Memory.
So far, by using Script Manager, and this Code:
busybox mount -o remount,rw /
busybox mount -t vfat -o umask=0000 /dev/block/vold/179:33 /mnt/shell/emulated/0
busybox mount -t exfat -o umask=0000 /dev/block/vold/179:33 /mnt/shell/emulated/0
if busybox mount | busybox grep vold/179:33; then
busybox mount -o bind /data/media /mnt/sdcard1
fi
I put it here: /system/etc/init.d
And tested it here: /data/
Running this makes all my apps stop working, and after a minute can no longer access the settings even.
When I plug it into a computer however, it is reading my Internal storage as the 64GB Card.
Any help is Appreciated!
This is some code I found and edited, so I'm not entirely sure of the Mechanics behind it.
Here are the Credits:

Having Problems trying to swap Internal SD with External SD

So I have been trying to swap my Internal SD with my External SD with methods like the one in this video:
But I have not been able to get them to work. This is what script manager says when I try the method from the video:
