I flashed 1.z8 bin that I downloaded from liggy's using Binflash GUI 1.63 and during the flash it started going slow at one address, but eventually completed. Then it returned a checksum error and then said error writing flash.
The DVD Drive now just blinks and won't eject or anything. I try to reflash with other bins but they all end up failing during checksum. The original factory bin also won't flash to the drive and fails in the same manner.
Drive is in failsafe or CORe mode.
Normally you just need to reflash properly with an official update/flasher.
But in your case something went wrong.
I would try to reflash the drive on another controller/in another computer first.
