Also the trick where you wrap one in a towel and let it cook itself.

That was just a low-tech non-targeted way to perform the same application of heat without breaking the warranty sticker on the console.

And it didn't actually work, because you can't get it to heat up to soldering temperatures that way (if you did get it that hot, the CPU cooler pressure would instantly crush all the BGA solder balls and render it a massive short circuit).

That only kind of worked temporarily because putting the system through thermal stress made things shift around due to thermal expansion, and possibly make contact again.
