Hi everyone, I'm having a really strange issue with one of my 360s. I have two Xbox 360s flashed to LT+ 2.0. One is a Liteon 83850c v1 and the other is a Liteon 74850c. With the 83850c Gears of War 3 plays perfectly. However on my 74850c the game has a number of issues, this includes getting stuck on loading screens in the game when booting up, failing to load game textures when it does boot up or just freezing a couple of minutes into the game and failing to install the game to the hard-drive when I try to do so. All of these issues implied to me that there was a fault with the DVD-Drive as the exact same disk works perfectly on my 83850c, and I've had similar issues with the same drive in the past with Modern Warfare 2 (it always used to fail to install). For those of you in the know, I tried the pot tweak method as I figured my laser must just be dying but that seemed to do nothing, I even adjusted it a number of times and went as low down as 3.05 on the ohm resistance. I also tried to clean the laser by carefully blowing it with compressed air but that did nothing either. Does anyone who knows what they are talking about know what might be up with my DVD-Drive so I can get it to play Gears of War 3? P.S A point that really confuses me here is I just went back and installed Halo Reach and it installed first time without any issues! so I'm really stumped on what's going on here. As always, any helpful replies from the pros on this site are much appreciated!
