So im trying to get cfw ultimate working, my ps3 is running 3.55 official so I downloaded the pup file, placed it on my USB stick fat formatted in ps3/update/ the PS finds the update on the USB stick and the install runs as you would expect up to the point the PS restarts. The PS them just sits with a reen light on and no image on the tv... I became brave enough to restart via the power lead and then I get the firmware was already at the latest version no update required.
I then thought I would use recovery mode, reflash of 3.55 then reflash ps3ultimate, same result no cfw and just the green light no tv image.
Any help well received, I want to run ps3 ultimate as it seems most up to date to me, if not guess its time to try nfw?
