XBtool 1.0.20 b2 *updated*
>> A new version of the XBtool(info) - Bios Packing, Unpacking, and Patching Tool - has been released.
What's new/fixed (1.0.20 b1):
* Embedded HD Key patch for Evox M7 and X2 4981.
Causes the hard drive key to be read from the kernel rather than calculated using the EEPROM & hard drive info. Only applies to unlocking. If you lock your drive while using this patch, the password will still be generated from the EEPROM and HD info.
Could be used to recover a locked hard drive. Could also be useful if you use an embedded EEPROM to help prevent your Xbox from being banned from Live! Using this patch you can embed a fake EEPROM and still keep your HD locked.
What's new/fixed (1.0.20 b2):
* Fix: bug disabled HD key embed in X2 4981.
