1633s,BS0Y stock or CS0T firmware?

I own a 1633s burner with the official BS0Y f/w on it,i’m getting great burns so far with DVD+R discs but with Dual Layer DVD+R the situation is very bad.
I’d like to experiment a little with the latest CS0T f/w so i need your guidelines on how to apply the new f/w in my drive.
Do i have to do anything before applying the .exe f/w file?


Go to here and download either of the CS0T patched files and run the executable. Reboot and the drive should be a 1653.
