[Answered] psgrade on a regular usb help?
can i get psgrade on a regular usb stick?
no, a standard USB won't allow a firmware to be loaded, it is only for storage, the only storage USB at the moment that will psjb or d/g is the E3 card reader, simply because the unit has a separate section for a firmware injection.
So to recap at the moment a handful of dongles exist which can modify your PS3, but all of them have require an amount of onboard flash nand memory, which will run as the PS3 boots up
