Updating to ixtreme 1 5
This version is for use with the Team Xecuter Unlocked DVD Replacement PCB universal for all Xbox 360 Slim DVD drives (Lite-On DG-16D4S 9504/0272/0225/0401/1071, Lite-On DG-16D5S 1175/1532, Hitachi DL10N 0500/0502).LT Ultimate does not need a full fw dump, it requires only the DVD key.
LT Ultimate requires the presence of AP2.5 Topology Data in place of the older AP2.5 Replay Sector, so backups made for the older i Xtreme LT/LT v2.0 will not work on LT Ultimate.
This version is for dashboard version 2.0.13599.0 – It is based on the latest firmware as updated by the recent dashboard update. The 13146 update flashed all phat Lite-Ons to the same version, 02510C.
