[General Questions and Answers] KnightDay:
Hey guys I tried switching my internal and external sd card by editing vold.fstab

Here's how it looked before switching it.

## Vold 2.0 Generic fstab

## - San Mehat (san@android.com)

##

#######################

## Regular device mount

##

## Format: dev_mount <label> <mount_point> <part> <sysfs_path1...>

## label - Label for the volume

## mount_point - Where the volume will be mounted

## part - Partition # (1 based), or 'auto' for first usable partition.

## <sysfs_path> - List of sysfs paths to source devices

{a

supported_exfat = yes

}

#dev_mount sdcard /storage/

sdcard

auto /devices/platform/mmc_host/mmc2

dev_mount sdcard /storage/

extSdCard

auto /devices/platform/sdhci.0/mmc_host/mmc2

#usb host device

{

media_type = usb

supported_exfat = yes

}

dev_mount sda /storage/UsbDriveA auto /devices/platform/dwc_otg/usb1

#usb host device

{

media_type = usb

supported_exfat = yes

}

dev_mount sdb /storage/UsbDriveB auto /devices/platform/dwc_otg/usb1

#usb host device

{

media_type = usb

supported_exfat = yes

}

dev_mount sdc /storage/UsbDriveC auto /devices/platform/dwc_otg/usb1

#usb host device

{

media_type = usb

supported_exfat = yes

}

dev_mount sdd /storage/UsbDriveD auto /devices/platform/dwc_otg/usb1

#usb host device

{

media_type = usb

supported_exfat = yes

}

dev_mount sde /storage/UsbDriveE auto /devices/platform/dwc_otg/usb1

#usb host device

{

media_type = usb

supported_exfat = yes

}

dev_mount sdf /storage/UsbDriveF auto /devices/platform/dwc_otg/usb1

Here is after switching it.

When I restart my phone after switching it, it gets stuck on the samsung boot logo. :(

So what is the proper way of switching internal and external sdcard of S duos 2.

Thanks in advance :o

By the way I attached the original vold.fstab. and this is my first post on xda-developers forum.
