if you are running 1.5 then just upgrade to custom firmware, there are lots of guides for this. Once done, just drop your cso file into the ISO folder and off you go.

I'm using the firmware 1.5 because of the fast loader i have.
And if i upgrade the firmware I may lose evrything in my memory card.

Huh ?

Why would you lose anything on your memory card ?

Why would you use fast loader ?

Fastloader, devhook etc are all outdated, custom firmware is all you need.
