I have used the method from
http://www.i-hacked....nt/view/263/62/ to fix my nephews xbox 360. It worked perfectly, and it has been three weeks so far. He plays the darn thing a lot, so he was a good test subject. I attempted to fix an xbox 360 I bought from Ebay with the RROD using the same method, but wasn't as lucky. My question - is the i-hacked method a fluke? Did anybody else have success using the i-hacked method? The Ultimate X-clamp fix and this one look similar. Should I focus on using the X-Clamp fix? Thanks.
I have three xboxes that I fixed using Team Hybrids method. Two were garden variety 3RROD, one was e74. It seems that while this fix definitely works, after getting the mod done, it can be a bit of a black art when it comes to getting them to run properly. They may boot up fine, but after a few hours or days, or after being left off for a few days, they revert back to being broken. So my experience has been that a lot of care needs to be done right at the end - don't overtighten the screws, don't leave them too slack, and don't tighten one corner at a time - tighten them all together. As an added measure, i added vga ram heatsinks to the two exposed RAM chips, the south bridge chip and the ana/hana chip. Now, I'm looking at making an extra fan shroud that will fit over the gpu heatsink and fit a fan to to it on the right hand side of the DVD drive. The fan will be mounded vertically, so it will suck in and blow cool air over the gpu heatsink, and get expelled by the stock fans. I think this extra belt and braces mod will cure the RROD problem permanently.
