Android 4.3 Swap External With Internal
Since baz is an obvious douche. Here's how you do it (and yes it's posted *somewhere* on the xda threads)
Pull your build.prop from your phone and add the following lines to the bottom: (adb pull /system/build.prop)
Edit the build.prop with Notepad++
If it contains the line remove ro.vold.switchablepair=/emmc,/storage/sdcard0 (or any variant - remove it)
Paste the following at the bottom of the build.prop.
# Switch External With Internal
# Storage configuration
Save the file, (at command prompt type)
adb shell mount -o rw,remount /system
adb push build.prop /system
These instructions are obviously not completely in depth and don't hold your hand all the way. You'll need to somewhat know what you're doing.
As always make sure to make a nandroid backup in the rare case that something goes wrong.
