DRW-3S163 to 1633s/1653 problems

I upgraded my 3S163, and now it won’t finish burning anything. It tends to get to around 80% or so and then the burnprocess just freezes. I’ve tried the stock firmware, then I upgraded to a 1633s and then to a 1653 (eprom and all), and still nothing. If anything, it’s gotten worse. I’d like to try the BSG3 firmware again, but I can’t seem to find a patched version that will let me install it, and I can’t seem to extract the firmware from the .exe installer.

Any ideas? Is it possible the drive has spontaneously become defective? Does anyone know where I can get a BSG3 firmware that will install on the drive?
