well i got retail 10.7.2 dmg i use myHACK to put it on my usb...then i took r:a:w:x86 kernel to see if i can get to the installation screen....first i use a simple -v flag to see where i might get errors at....but after it loads all the extensions the screen flashes that the caplock light flash then the screen lights up again but it stays black...i left it for over 10 hours(went to sleep)woke up still a black screen...so i tought it could be a graphics problem so i added the ATY kext that worked on my snow leo but still nothing ...so im bummed out because since i cant get a verbose output after the flash screen i cant really say what the problem is
