IPhone 3G frozen when I tried to upgrade to 3.1.2

This is not the first time my iPhone 3G gets frozen and unresponsive when upgrading.
Two months ago, when I bought it second-hand, I’ve tried to upgrade from 3.0.1 to 3.1 and it was a nightmare that lasted for days...
Eventually I succeeded, after countless attempts using three different computers.
After I finally got to upgrade the phone worked really fine until now, when I was dumb enough to try upgrading to 3.1.2.
Now the phone is frozen and unresponsive, stuck on that black screen with the iTunes logo and the USB cable picture.
Here’s what I get every time:
“the iPhone could not be restored. An unknown error occurred (13)”.
I’ve already read and tried the following, without success:

Please help.
