iXtreme LT v3.0 - No More AP25
Yeeeah buddy, c4eva comes through with the answer to Microsoft's latest roadblock by announcing iXtreme LT v3.0. In other words, the silent AP25 challenge update has been defeated across all consoles. As an added bonus, c4eva has also announced that LT v2.0 firmware for Hitachis is completed and has not been affected by the silent updates.
Going more into detail, c4eva has worked on an idea where the need for the specific AP25 patches for each challenge table are eliminated. To take its place, profile data will reside in each backup image where it'll be able to respond to every AP25 challenge thrown at it regardless of the changes made to the dae.bin file. With the new profile data in place, this will mean that the format of backups from here out will change. Subsequently, there will be changes not only to the firmware but to Xbox Backup Creator and abgx360.
Regarding the LT v2.0 firmware for Phat Hitachi drives, it is still planned for release. Now if this is the "silver bullet", I wonder what the golden gun will produce.
