I did read the text in red, I also read the text on the ipod installation beta page saying:
"NOTE: These instructions are known to have problems with the 1st and 2nd Generation Mini and 4G (Greyscale) ipods - Rockbox loads correctly, but the original Apple firmware will not start. Also, ipodpatcher does not yet work with the 3G (third generation) ipods. If you have one of these ipods, you should continue using the old installation instructions linked to from the iPodPort page."
As I have an iPod mini i used the old instructions as instructed. And I have just followed the beta instructions and i still have the same problem: The bootloader screen appears, then the rockbox logo, then a picture of a USB cable, then it shuts down. And now it won't load the original firmware.
