Sorry Milhouse but I never had to do that. all I do is plug in the 770 and once it comes on it flashes away... never had to use the home and power button I think that part is useles unles you have a brick 770 I think thats the only time you have to use that combo... Just a guess but sincerly I had never done it that way and never had a problem. Tell you the truth I dont think I never even read that far.
