Ok, so I am not new to xbox-scene as I have used the technical advise found here to mod My xbox. I have been having the same Issue with the hard mod which reoccurs between 3 and 9 days. Everything works great. I installed a new HDD, with dash and all other kinds of homebrew software, and everything is still golden. I can play my games and it powers up fine.
Now... after what i can the "grace" period where it likes me, the box then decides to start fraging. Ive opened it up twice now looked over everything, and havent really found anything wrong. I then reflow some of the solder points (same ones each time... D0, BT, and a few on the MoBo end of the pinheader). afterwards, I put it all back together and it works great for the "grace" period once again until it decided it doesnt like me any more.
Any ideas why its doin this.
I thought it might be my D0 wire being too small to suppot the necessary current, but I havent found the wire melted at all. I thought it might be the D0 point, but if i ground the wire then the box frags. I thought it might be the chip, but if it woks just after a reflow of solder that is most likely the last reason.
Any help would be appeciated. Props out to all who contributed to Xbox-Scene, the site and forums are awesome souces of needed information.
