[How to] Enable write permissions to external sd!

We had this same problem on the G3,

solution is simple use root explorer and edit system/etc/permissions/platform.xml with the built-in editor.

<permission name="android.permission.WRITE_EXTERNAL_STORAGE" > <---Look for this
<group gid="sdcard_r" />
<group gid="sdcard_rw" />
<group gid="media_rw" /> <---Add this
</permission>

save and restart, apps will no longer require permission to write to the external sd card, or delete files from the external sd card(music players, ect.)
