I'm re-reading my post and I think I wasn't clear.

Just tried to say that I updated successfully and without problems, however it took me some time when I was trying to install the drivers again. It took me a little more time but everything worked fine, excepting for the USB. To read contents from the USB pendrive I had to plug it in before starting Leopard. Not really something to care about. The real reason which I decided to install all again was because I installed something called myHack Installer 1.0 that rewrote the Chameleon 2.0 and didn't let me enter to Leopard again.

When you say that the update didn't worked for you, what exactly happened? And which model is your Toshiba? Just trying to compare experiences dude
