Why did you use a firmware update that wasn't for your drive? Dell's site only carry's updates for
TSST TS-L633C 12.7 SATA Trayload 8X DVDRW, v.DW60, A08
TSST TS-L633J 12.7 SATA Trayload 8X DVDRW
No wonder you broke it!
You'll need to scour the internet for any firmware updates for that drive. If you find one and it still doesn't work then you've bricked your DVD drive.
I installed this firmware update since it came under the name XPS L502x which is my laptop.
Then its time time for you people to remove this firmware driver from showing up for drivers updates of XPS L502x.
Do you Have any idea about where can i get the original firmware?
As I mentioned previously, Dell's support site doesn't show any firmware updates for your DVD drive under XPS L502x, so I don't know where you think you saw it...
