Well, I tried it, and it pretty much works.
Things you will need:
Tools to dismantle a 360
12 pound weight. (No kidding)
A 360 with error code 0102
Well, after dismantling the 360, you take off the fan shroud, and let the 12LB weight rest on the GPU heatsink, and let it overheat. It works for a while, but if you keep the weight on it, it doesn't crash. At all. Im kinda freaked out it actually worked. I still would suggest you keep that weight on it.
Here are some links, the first one is on how to dismantle the 360, and the others are things you should do to evade anything else from happening.
Fan shroud mod.
Thermal paste mod.
