Philips PBRW4816G problem

I have a problem with a Philips CD-WR drive CDD6911 - model PBRW4816G. I was writing a CD with software “Alcohol 120%” and the PC crashed during the process. After the restart Windows didn’t recognize the drive anymore and in BIOS the drive is seen something like: “яяяяяяяя яяяяяяяяяяяяяяяя”. On another systems, some of the burning software sees the drive with the same strange name.
When I try to update firmware with flash tool, downloaded from Philips page, the Drive was identified like Non-supported and the process canceled.
How I may update firmware?
