When I was trying some stuff you post here about ps3, one time I took my hdd out of my ps3 and connected it to PC. I don't really remember if I've formatted it on PC or just connected through USB but when I put it back to ps3 it went: "Error occurred", and I needed to format my Hdd, and MY FIRMWARE WAS BACK TO 2.72 - the one that I bought my ps3 with.
So I was wandering if it would work for someone who have upgraded to no OS maybe to regain it?
Yes indeed, i have readed too.Some Ps3 is the storage of the Firmware on the Harddrive. I think, it was the Pal Model 80gb fat, some never then the 40gb Models.But newsest, Models dont support anymore. Maybe its a rumor, but i have read this in german Help forums, who have buyed a new Harddrive. But, i dont think its avaiabele an the newsest Updates, maybe 2.15, 2.30 ?
I have pal region system with 80gb onboard hd. Right now i tried to replace my xbox360 20gb HD with 80GB ps3 HD, anyway when system start it's can't load the xmb and ask you to connect your dualshock controller via usb and press the home button, then when you press the home, appears new system message which says: if reboot can't be solution for this problems with firmware then insert some USB storage device with files of firmware version 3.15(already installed) or newest to format boot partition of HD. Which means it's no way to downgrade PAL 80GB.
