Well I've got to admit, I didn't think that baking my Xbox 360 was a smart thing to do. I had my original xbox 360 that I got on launch day which RRODed on me. I've previously done the xclamp mod and got some more life from it, but the RROD came back again. After reading this thread, I though "what the hell", it's not working and it's collecting dust, the worst that can happen is that I have to explain to the wife why the kitchen smells of burnt electrics.
So I wrap most of the motherboard in foil to try and protect plastic bit and capacitors, and whack it in the oven for 15 minutes at 230C (about 450F). It smoked a little (only a very little) and some of the capacitors were bulging a little, no real damage. I had a hard time plugging the power cord back in again. It took a few attempts and a bit of force but it went in eventually.
Finally... the result? Well, much to my surprise it bloody well works. I'm impressed. It just seems wrong but I'm not complaining. I don't know how long it will last, but considering it wasn't working at all... every extra day is a bonus.
Thanks to all the pioneers who went before me.
