Could you please help me?! After reseting 7170 bootcode and installin 7173 firmware DVD-ROM fails to burn anything using ImgBurn. Everything just stalls at “Writing Lead-In”. Then I reverted everything to 7170 again but this changed nothing!!! It stall s at the same place. At the same time I successfully burnt CD-R using Windows XP built-in tools.
Guess you toasted your drive.
No, now everything is fine my mistake was the following. I used btflash-x17xAp.zip instead of btflash-x17xA.zip. I hope this will help anybody.
