Tried something a few years ago with a bad flashed DVD-drive in a notebook (no more recognized) :
So I had to find the same model drive (working) ... and once the notebook has booted with the working drive, I just replaced it with the wrong one, and could flashed it back... It revived !
So, try it by unplugging the good drive and replacing it with the bad one, once the PC booted ... without power off, and Flash it.
I hope you'll undestand my French English
