Switch internal and external memory card​

Mount the external SD in place internal SD.

Option for editing via Root Explorer

Go to the folder "System" to set it right R / W.

Find the file "build.prop" and open it as a text.

Find the line "persist.fuse_sdcard = true" (in the middle of the file)

Change the "true" to "false". It turns out "persist.fuse_sdcard = false"

Save and exit. To turn off the simulation data / media on the internal SD

Go to the folder "/ system / etc" and find the file "vold.fstab"

Separates it as text.

Find the line "dev_mount sdcard / storage/sdcard1 auto / devices/platform/msm_sdcc.3/mmc_host"

Change the "1" to "0"

Add the line "dev_mount external / storage/sdcard1 auto / data / media"

Save and exit. Now External SD card is mounted in place internal SD.

Restart.

Option for editing via ADB

Line by trying to drive in the command line:

Enter only written in blue.

adb shell

su !Get Root

mount-o remount, rw / system !Mount Systems

mv / system / build.prop / system / build.prop.old !Rename the build.prop in build.prop.old

cat / system / build.prop.old | grep-v persist.fuse_sdcard = true> / system / build.prop !Remove line persist.fuse_sdcard = true in build.prop.old and save as build.prop

echo "persist.fuse_sdcard = false" >> / system / build.prop !Adding line persist.fuse_sdcard = false in build.prop

chmod 755 / system / build.prop !Set permissions on the file build.prop

mv / system / etc / vold.fstab / system / etc / vold.fstab.old !Rename vold.fstab in vold.fstab.old

cat / system / etc / vold.fstab.old | grep-v "dev_mount sdcard / storage/sdcard1 auto / devices/platform/msm_sdcc.3/mmc_host"> / system / etc / vold.fstab !Remove line dev_mount sdcard / storage / sdcard1 auto / devices/platform/msm_sdcc.3/mmc_hos in vold.fstab.old and save as vold.fstab

echo "dev_mount sdcard / storage/sdcard0 auto / devices/platform/msm_sdcc.3/mmc_host" >> / system / etc / vold.fstab !Adding line dev_mount sdcard / storage/sdcard0 auto / devices/platform/msm_sdcc.3/mmc_host in vold.fstab

echo "dev_mount external / storage/sdcard1 auto / data / media" >> / system / etc / vold.fstab !Adding line dev_mount external / storage/sdcard1 auto / data / media in vold.fstab

chmod 644 / system / etc / vold.fstab !Set permissions on the file vold.fstab

You can also through the terminal emulator, but without the adb shell.

As for the line "dev_mount external / storage/sdcard1 auto / data / media" in "vold.fstab". Logically, the stick should be mounted inside the place outside, but it's not happening. How did you know the contents of the internal flash to be (always was) in "/ data / media".

Do you have a question:

- A sense of this line?

Answer: - If its not say when entering the settings / memory crash bug.

I tried to write a line in this form: "dev_mount external / storage/sdcard1 auto / devices/platform/msm_sdcc.1/mmc_host". As such, the phone sees the external SD card but says that it want to format. Formatting is not happening. In the setting of active memory item "Mount SD", but also the sense of it is zero. Perhaps this is because the kernel does not support flash file system ext4.

I decided that I do not need built-in memory as an external SDi decided to completely give it up for memory applications (data / app).

If you want to install in the internal SD as an external SD:

OR. Go to the terminal and drive a "su" then "mount-o bind / data / media / mnt/external1". With this method of memory will be mounted at up to reboot.

OR. Create a file with the following content:

#!/system/bin/sh
busybox mount -o bind /data/media /mnt/external1

File Name: name

And open the file in the "SManager ads" put the mark on the "SU" and "Boot". The "Save" and "Run"

I tried to add a script in "/ system / etc / init.d" named "11mount" but he either did not run or he should run after loading the phone.

Be sure to download content from the "data / media" in "/ storage/sdcard0" as earlier in the "media" Many applications store their data, and now "media" is not available at "/ storage/sdcard0" as before.

I speak bad English and use "google translate". Original in Russian here.
