Ok i have two ps3's one that is on firmware 3.55 and another that is on 3.55. 1 is a launch 60gb model the other is an 80gb model. i have problem trying to downgrade both of them. a while a go i downgraded the 80gb model to 3.41 then upgraded it to ofw 3.55. now when i try and downgrade it again it just keeps booting up in to the service mode. now for the weird part.
the 60gb launch model was on 3.41 and i up graded to 3.55 ofw i have never downgraded this model. well i tried to downgrade it and it does exactly the same as the 80gb model it goes straight back to the xmb in service mode.
any help would be very helpful as it is driving me nuts. i only want one ps3 downgraded to firmware 3.00 to get ride of that cinavia crap. thanks.
