Possible to flash a Winchester DVD drive now?

Is this possible? (Yes I know it's not that practical, but I'm just curious.)

  1. Use FreeMyXe to get CPU key.
  2. Dump NAND with Simple 360 NAND Flasher.
  3. Decrypt it with the CPU key to get DVD key.
  4. Use the DVD key to create and flash modified firmware to unlocked LTU2 PCB.
