hi kool2kooluk
go to intallations type in 0000
then look for s/w update in the menu
just click it , should run on it's own , will d/l unzip then flash the box
after that you need to delete all channels and factory reset to get rid of old s/w so it doesn't conflict with new one
also this is a s/w update for the box not for channels , hope that help's.
