C4E released a new version of the iXtreme LT+ modified FW for ("phat") LiteOn (74850, 83850V1, 83850V2, 93450) and BenQ DVD-drives.

What's new/fixed:
- xbox 1 backup support (iXtreme compatible, DVD9 only)
- improved pfi support

There's also some WIP news about the LT+ FW for Hitachi-LG drives on team-xecuter.com:

Plus after much work and heavy testing, C4E has finished the LT+ for Hitachi 78 and 79 and it is confirmed that they now boot AP25 backups ! We are currently testing and hope to announce the official release shortly. There are also plans to make LT firmware for the older Hitachi drives but without Ap25 as it’s not required. LT+ for Slims is the priority at the moment. FYI iXtreme 1.51 still works just fine with AP25 (many are still using the older Hitachi’s on XBL – however we can’t guarantee that it is XBL safe so use at your own risk).
