Default [Q] broken volume buttons & broken rom...need help [solved]

My i9250 both volume buttons are broken
im just flashing a rom via sideload mode(by toolkit)
but i press a random key accidentally
which make the phone reboot and flashing still in progress...

now it stuck on the cross logo
is there any method to boot into recovery/fastboot mode
without volume buttons & rom...?
or other possible solutions?

sry for my bad english
thousand thanks
