mtkFlash Problem

Hi I am trying to flash my laptop sony rw dw-d22a after a misflash, (Drive does not show up anywhere in windows and the door won`t open) I am using mtkflash 1.83c in dos with DRU-710A firmwares, I have also tried several other bin files:

However I keep getting the same result:

Port: 170, Master/Slave: a0

then nothing, after waitng for over half an hour if I press Esc I get:

Status = 00, should be 70
ERR: user break

Any help would be gratefully recieved.
