[Android Software/Hacking General [Developers Only]] funkypotatoe:
ajeevlal, elnney, crash_b (i hope everyone is spelled correct), looks like we all are having same problems: missing sd-ext mount point & missing fstab (mine is just named "vold.fstab")

This script WILL NOT dump any PHONE NUMBER, IMEI, DEVICE NAME
SERIAL NUMBER and ANY PERSONAL INFORMATIONS...

But Please provide me your Device Name and ROM when you
submit it on AD2SDX Thread...

Mounting data, sd-ext, and sdcard...
