In all fairness, you asked a group of people who solve problems w/ rocket launchers & flamethrowers.
The microwave came to mind to fry the chip, but I've never tried this & don't know if it'll leave obvious signs of
abuse. The shower is simple water damage & as long as you thoroughly dry it shouldn't leave any obvious signs.
If someone from MS is reading this, what did you expect? You finally admit there's a problem w/ your consoles &
now you jack us around on the warranty (well, it's not broke ENOUGH).
Anyway, good luck Ryan, hope you get this resolved.
