The RRoD 360 repair process has been straightforward so far. (After all, Microsoft has certainly had an ample volume of opportunities to improve it.) The online repair form was straightforward, and my empty pre-paid shipping box arrived yesterday.
Everything needed to package the console for return was included: a plastic bag for the console, padded foam, large strip of packaging tape, shipping label, small form (in English and Spanish) and clearly written photographic instructions. Paying for door pickup would have been nice, but that’s not a big deal. I’m off to drop it off at UPS right now.
