Hi. I have a fat and a slim PS3 with the same problems. I have new drives for both of them but I dont have the old drives anymore.
Both of the drives have been formatted in my PC and every time I try to start the PS3 they fail and say that the OS couldnt start. I have tried all the things in the recovery menu and now I am stuck.
I have also tried downloading the different firmwares from this site but they always say "corrupt files" when I try to open them.
Please let me know what I can do to fix them. And I will NOT send them to Sony. Thanks
