Guys, do not recommend the XClamp mod unless the console has been previously modded and opened. If not, send it to Microsoft. Xbox Live was having problems these past two weeks and it is known it can freeze the Xbox. Still, the X Clamp method is not permanent and WILL fail.
It's clearly stated in the first post that the box has already been opened. I wouldn't have recommended xclamp replacement if it was still in warranty.
