yes but my problem was that windows did install drivers automaticly but i did choose find auto, and in home premium you cant change windows behavior, on ultimate u can choose for windows not to install them wich makes possible to choose drivers.
and yea i said so u cant go back if you flash it, but at least im thinking maybe to buy another key l8r on, just to be able to use their releases.
But be aware that if you removes the current flash, its gone no more support from ps3key team.
yes FLIP software but you need to put it in programming mode, insert/remove like 4 times until both leds lit up when inserted. (must be done i think within 10sec)
