Just thought I'd share this experience with everyone for the record.
I ordered a Xecutor 2.3b Lite from
http://www.xbox-modchips.com, and it took about 2 weeks to arrive. I went about the install and everything went just dandy (I'm very experienced with soldering so it was a clean and nice job.) Booted it up and loaded evox and all the goodies, and had a jolly good time with it.
About 5 hours later, I'm out of the room, and I faintly smell ozone. "Oh #*@$!" I think and dash to my server room. Everything is okay. I run to my desktop, everything is okay. I figure I must have imagined it and walk back to the xbox which is cycling all 3 led colours, and showing a black screen. "Uh oh."
I figure something must have been jostled like the d0 wire or something, so I pop it open and examine, everything is perfect, soders are clean and rock solid. Then I notice the chip has a big black scoarch mark down the side. On close inspection I can see that on the burnt edge, the top layer of the chip has totally burnt off and the metal underneth it has burnt right through and is in 2 pieces. Pretty clear indicator of where things went wrong.
So clearly this chip is defective, and I'm of course wanting a new one (and my xbox is useless without one, seeing as I've replaced the dash... (and yes I could unlock it and put it back on my pc but thats a HUGE pain in the arse). The policy says on the xbox-modchips.com site that they will replace defective chips, and so I emailed them explaining what happened. It's been one day and I have not recieved a reply as of yet.
I'll keep this thread updated on how they handle this and we can all see how this plays out. <
