i have a 750
i had the pdx rom kc3 installed and wanted to go back to jp rom. went in to d+m menu
put in cf card and hit restore nand .
it loaded when booting up the white sharp screen came up and in japanese told me to wait.
then another screen came up told me to wait another minute in japanese. then this flashed off to a black screen which had entering run level 5 and back to screen telling me to wait this happened 5 times then just hung
at black screen entering run level 5.
now i can not get back in to D+M menu . when i try to go to d+M menu i just get a white screen.
i can use ok and power on to load rom which i have put pdx rom back but i want to get D+M menu back.
does any one know how?

?
thanks
