So i have a fat piano black version of the ps3, its 160gb. I have a flash"drive". its more like a portable hdd. so idk if it will work. But i've tried multiple times to update it through XMB and it just will not work, my ps3 is on 4.50 version.
Any ideas guys/gals?
Because you need a hardware flasher to downgrade it.
Or you can pay someone to downgrade it for you
Check PS3 Marketplace section if forum for downgrade installers.
