updateFirmwareFromFile.sh - I need this file

Hi,
Messing around with update of my WD Passport wireless freshly purchased, I’ve figured out, that my topic file:
updateFirmwareFromFile.sh is completely empty.
Could anyone put here its content? Its short one, about 3-5KB i suppose.

I hope its the culprit of hanged update of my unit. On my device no method works: automated, manual or from SD. Nothing, still 1.01.09

any1?
Every wireless passport has this file in it, connect with winscp through ssh, and its in usr/locale/sbin…
