Fair warning... I was messing around trying to make a turtial abought this lastnight when i found the ipods boot splash screen. So i found a paw print and swaped the file out..well i goofed up so how. *face paw* Its not booting, not powering up at all ughh.
Download ipodwizard and install
load the Ipods firmware
click on pictures
Scroll over till you see the do not disconect icon
youll notice the hight and with in pixles for that icon
resise you new icon to that sise and save it as a bmp
on ipodwizard click load bitmap, find your newly resised image
last click WRITE the edited firmware will be loaded on the ipod
your basicly safe from major goof ups as long as you dont go playing with the boot side of things. If things do go right just restor the ipod from itunes
