This will work with any ROM 11extsd2internalsd
Folks,
This is my 11extsd2internalsd:
#!/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
#All credits to Mattiadj of xda forum for the idea and script and to mike1986 for the cmw zip.

#Script Modified for U.S. Galaxy S3s by Zedomax at GalaxyS3Root.com to be compatible when sdcard is not inserted.
busybox mount -o remount,rw /
busybox mount -t vfat -o umask=0000 /dev/block/vold/179:33 /mnt/sdcard
busybox mount -t exfat -o umask=0000 /dev/block/vold/179:33 /mnt/sdcard
if busybox mount | busybox grep vold/179:33; then
busybox mount -o bind /data/media /mnt/extSdCard
fi
Please notice where it is mounting the SD Cards. So if yours quit working with a new rom then navigate with root explorer to /dev/block/vold
There should be 2 files in there. examples: 179:32 and 179:33 you want to record the second file name.
Then open your 11extsd2internalsd file with Notepad+++ and change the 3 locations to the second file name you found in dev/block/vold save changes and replace your old 11extsd2internalsd file.
