If Microsoft's firmware update made his console unusable, then they should have offered to replace or fix it, unless he modified it in some way which contributed to the update rendering it unusable. It's as simple as that.

To people saying he is asking for too much, I completely disagree. Why should he only be entitled to a replacement? They already refused that. If a customer has to go through the legal system to remedy a situation where the company's actions are, frankly, indefensible, I think a message needs to be sent; if you engage in this type of practice you'll be punished. And not only for the amount that you should have had to pay in the first place.
