The easiest way to install Canola is to use the one click install; use wifi to connect your device to the internet and go to http://openbossa.indt.org/canola/, then click on the green "one click install for all devices" icon at the top of the page, the rest of the install process is straightforward - hence "one click", it definitely works as I used it to install Canola on my 770 this morning.
