Make external storage the internal storage

For anybody who wants alot of internal space by switching your external sd to internal storage do the following: First find the vold.fstab file in system/etc. Once you find it you will need to edit it with an app like root explorer. Scroll down the file until you see the internal sd card line change the 0 to 1. Then in the line that says external sd change the 1 to 0. That's it very simple. Now your external sd will be your internal space. Make sure the vold.fstab file has r-w-.r-r or 644 permissions and owner is root. Now reboot and your done. You should now have switched your external space for internal space successfully!!!

Use this zip just unzip and take the file out and place it in system/etc. With 644 or r-w-r-r permissions and owner as root. Then reboot

I was wondering if this was possible on the galaxy reverb. Here is the vold.fstab.

Not familiar with the phone but it looks like all you have to do for this is switch the dev mount sd card with ex sdcard just switch the order so it reads the mount differently. The s2 uses 0 and 1 but basically it should be the same except it uses the words sd and ex instead.

Just a file located in your system/etc that I modified to make your phone mount external sd as internal sd to give you way more space for apps and data files for games or music etc.

What happens to the current data? Is it transferred to the external SD? Or just for new data that is written to the "internal memory"?

Not trying to hijack the thread but, for those of you on a TW based ROM, if you wanna swap the internal and external storage, look for the following lines in the vold.fstab file:

internal sdcard
{
ums_sys_path = /sys/class/android_usb/f_mass_storage/lun/file
secure_format = enable
discard = enable
}
dev_mount sdcard /storage/sdcard0 28 /devices/platform/msm_sdcc.1/mmc_host/mmc0/mmc0 encryptable_nonremovable

# external sdcard
{
ums_sys_path = /sys/class/android_usb/f_mass_storage/lun_ex/file
supported_exfat = yes
android_secure_containers = enable
}
dev_mount sdcard1 /storage/extSdCard auto /devices/platform/msm_sdcc.3/mmc_host/mmc2/mmc2

Where is says dev_mount sdcard /storage/sdcard0 under internal and dev_mount sdcard1 /storage/extSdCard under external, just swap sdcard0 and extSdCard, save and reboot and the storage will be swapped. Tried it myself and tried swapping back successfully with no need for wiping the cache/dalvik nor with any bootloops. The instructions in the op will work but only for cm, aosp etc. Word of advice though, once you swap the storage, you will no longer have the ability to unmount the microsd card in order to hot swap it. You will have to shut down the phone before removing the microsd card unless you swap back. Also, any apps that have data stored on the internal storage will need to be ran in order for the extra data to be redownloaded to the "new" internal storage.
