have successfully dumped the keys of the newest (previously un-moddable) XBox 360 LiteOn DVD drives.
The Liteon 83850-v2 and Liteon 93450 DVD Key can now be dumped. With that DVD key, you can install any flash-able DVD drive to that XBox 360.

â€¢ Put the switch in the other position (so that 101 is connected to 3,3V)
â€¢ Now read...
