Hello everyone this is my first post here plus i'm new here also. I am have a issue with my 360, it freezes on startup them i get lights 1,3 and 4 flashing. i went through the code setup and i'm also getting a 0020 code. It says unknown for that or possible overheat. I did the fix for the overheating issue( I've fixed this problem on my other 360 and it works awesome. that system is jtaged so i never go online with it. the one i'm having a problem with at the moment is the one i want to setup for kinects and go online. any help is greatly appreciated.
