If I install manually and run ipodpatcher.exe it says successfull! Hmm! Then it says on my ipod 4gen greyscale: Error,Bad checksum. Insert firewirecabel or hold Menu+play to reboot??? I did not use the original cabel/ I used a usb cabel from a newer Ipod Classic! Could it be a cable problem??? See I have no ports on my laptop where I can connect the old cable. When I try using the Rockbox Utility it won't install the bootloader??? Happy for help on this!!!
