Samsung sc-152l not working after flashing!

i flashed my samsung sc-152l cd-rom drive with “c101” firmware revision and the drive is completely dead. i flashed the drive with the wrong firmware. i have also tried using mtkflash dos and windows version to reflash the drive but to no help. also used samsung’s own flashing utility but that also didn’t solve the problem. Can anybody help me? are there other utilities that can flash samsung cd-rom drives? and where can i download it. The drive is not detected and indicator lights do not flash at all. i even tried flashing with the old firmware “c100” but doesn’t solve the problem.
thanks in advance
