LT+ 3.0 released for most xbox 360 slim liteons

by dsiso on January 16, 2012

Right on time comes the release of LT+ 3.0 for Lite-On 9504/0272, 0225, 0401 and 1071 all of which are firmwares seen on the DG-16D4S drive model seen only in the 360 slim. Do note there is also the Lite-On 1175 (also only seen in “slim” 360s) meaning there is only that and Hitachi 78/79 drives (as well as the as yet unhacked slim hitachi) in need for a LT+ 3.0 release- remember non 78/79 hitachi drives and samsung drives do not feature AP2.5 and so do not need this. Much like the other LT+ 3.0 releases this adds support for the “topology data” which can be used to completely bypass AP2.5 and dodge the need to reburn discs whenever microsoft updates the dashboard or more recently where it applied unique per console updates silently (the event that triggered the release of this method).

Official release of the iXtreme LT+ v3.0 for 0272/0225/0401/1071 slim Liteons
– Support for topology data on AP25 enabled titles. Will correctly answer any ap25 challenge eliminating need for dae.bin to create a backup.
– No need to make new backups everytime dae.bin is updated on console
– Extra support for rare firmwares
Topology Data
————-
When ap25 was first introduced I devised a way of calculating any challenge which I called the silver bullet which I made reference to along time ago.
This was withheld until it was absolutely necessary. It was easier to replay the fixed challenges.
With unique per console ap25 challenges it has become necessary to use the silver bullet.
A series of measurements are taken across the disk. This topology data is then used to calculate a response to any ap25 challenge.
It is very important that the drive used to create the topology data is reliable at reading discs as bad topology data equals bad ap25 responses.
Liteon drives using 0800 v3 seem to be more accurate for this purpose. Only ap25 enabled titles require topology data. Activation of ap25 on older non-ap25 games although technically possible is highly unlikely.
Currently topology data for xgd3 titles are similar and topology data from one xgd3 title will pass on another xgd3 title although this is not advisable.
Per title title topology data is best as there are slight differences between titles and newer titles could have different topology than existing ones.

One liteon to go and four Hitachis. Have a great year everyone.
Thanks go to Team Jungle and all testers for their hard work and efforts in the development process.
Thanks also go to Team Xecuter for their support to this project.

Do note since the release of original liteon and benq LT+3.0 we have also seen the release of ABGX360 1.0.6 that added nice and easy checking and support for this new data although you can still download and patch if you want.
