Xbox related commands

Enable Unlock 1 (xtreme) state

Supported by: Kreon 1.00

FF 08 01 01

Enable Unlock 1 (xtreme) state' as we already know it from the 360 xtreme modded drives. This command is supported for legacy reasons only. Custom applications should use the new 'Set Lock State' instead.

Set Lock State

Supported by: Kreon 1.00

FF 08 01 11 xx
  • xx=00 - Drive locked (no unlock state)
  • xx=01 - Unlock State 1 (xtreme) enabled
  • xx=02 - Unlock state 2 (wxripper) enabled

SS extract command

Supported by: Kreon 1.00

AD 00 FF 02 FD FF FE 00 08 00 xx C0

This is the well known from the xtreme firmware.

Get Feature List

Supported by: Kreon 1.00

FF 08 01 10

This command will return a list of the additional features supported by the drive. All values returned are 16 bit values, and the list is terminated with null (0x0000). The two first words of the returned list always reads as 0xA55A 0X5AA5 in order to guarantee that a reply from a drive not supporting this command correctly isn't mistaken for a feature list.

An example feature list could be: 0xA55A, 0x5AA5, 0x0100, 0xF000, 0xF001, 0x0000

This list would indicate that the drive supports XBOX360 Unlock 1, Lock and Error Skip, as it can be seen from the values defined below:

XBOX 360 related features:

  • 0x0100 : The drive supports the unlock 1 state (xtreme)
  • 0x0101 : The drive supports the unlock 2 state (wxripper)
  • 0x0120 : The drive can read and decrypt the SS
  • 0x0121 : The drive has full challenge response functionality

XBOX related features:

  • 0x0200 : The drive supports the unlock 1 state (xtreme)
  • 0x0201 : The drive supports the unlock 2 state (wxripper)
  • 0x0220 : The drive can read and decrypt the SS
  • 0x0221 : The drive has full challenge response functionality

General drive features:

  • 0xF000 : The drive supports the lock (cancel any unlock state) command
  • 0xF001 : The drive supports error skipping

This is the complete list of defined features at the moment. If you're working on a custom application you might want to contact me in order to get the latest list.
