I do not know where my problem is. I updated my XBox 360 to the 2.0.13599.0 system update then I found out about Team Xecuter and bought the X360USB PRO, CK3 PRO, CK3 PROBE 3, and HDD ADAPTER. I used these (without the HDD Adapter) to flash my Lite-On 74850 drive for the first time to iXteme LT+ 1.91. It did not work, I do not know why (part of the problem). I used the http://www.team-xecuter.com/forums/showthread.php?t=61803 guide and the DVD key was verified with no problems. I then re-flashed using this tutorial: http://www.team-xecuter.com/forums/showthread.php?t=66257. On both I used Windows 7 Ultimate 64-Bit with Disable Driver Signature Enforcement start-up. When I try to play a regular 360 game and a backup game, it reads as a DVD and shows this image: http://img208.imageshack.us/img208/9277/dscf1275g.jpg. So now my 360 does not read games and I do not know what to do.
