here is what i have tried up to now

using Flashtool

flashed it with original rom (just stoped at logo when powed up)
tried other roms (just stoped at logo when powed up)
so tried to go into fastboot mode looked all over to find that i have to Press and hold volume up and put the usb in (nothing it just boots up to the logo)
all other buttons puts it into flash mode
and i have used Flashtool-drivers to put fastboot mode drivers in and i have tried fastboot mode on my friends mobile and it loaded up

and i have tried Emma tools just says phone locked and will not let me do nothing

all i need to do is some how get it into fastboot mode to flash the Ray Kernel - ST18 - Build 62 - 69 image so it can load pass the logo (i think)
