'c4eva' and 'Team Xecuter' have issued an statement on their upcoming plans for the currently 'uncrackable' Lite-On 1175 Xbox 360 drive
So it seems once this new board is available from TX, 'c4eva' will release the firmware for the Lite-On 1175, as the SPI is also locked on the DG-16D5S in addition to new firmware encryption used on v1175, so the new replacement PCB will allow the user to freely update drive at will with no problems.
