Oh I didn't see your comment right away. Yes I did hear about the mod you mention but what I actually did years ago was the Reset Glitch Hack (RGH) on mine and several other 360's. It required soldering in a tiny piece of hardware which required you to solder to the smallest of pads on the motherboard. I remember at the time I had the cheapest junk soldering iron and nothing to help magnify the board and the pad you need to connect a wire to is literally smaller then a pen tip. Many people screwed up and lifted pads causing big problems for their 360. I had some previous experience soldering and managed to have no problems with the install.

In the end my RGH worked really well and it would boot first try every time, some people it could take like a minute to actually boot. Then it would load into custom firmware and I was able to do what ever I wanted. I still have the thing and it still runs with an external HDD with about 1000 games (all personal back ups of course) and my kids never knew how lucky they were to be allowed to play all my games I had backed up.
