Firmware Update via SSH

My UI stoped working, got SSH.

I did exactly as printed in the 1st anwser.

MyBookLive:~# /usr/local/sbin/updateFirmwareFromFile.sh /DataVolume/shares/Public/apnc-021009-124-20111113.deb
updateFirmwareFromFile.sh:11/11/12 10:52:21:: ( /DataVolume/shares/Public/apnc-021009-124-20111113.deb )

Then nothing happens. I read that there is no progressbar etc but I have waited 30 minutes and UI still does not work. The share is avaible 8as before) though, and I can ping it. What did I do wrong?
