This happened with 2 Xboxes I've had for a while. One had the Penny Trick on it and worked fine down the road for months until the most recent Ban Wave happened. Thankfully it stopped me from playing on that single day. I fixed that issue with the X-Clamp fix and everything worked fine. The Second Xbox I acquired from eBay and fixed it with the Penny Trick, then had to do the X-Clamp Fix on that one after it RRoD'd. The First one I had to keep turning off and on to tune the Drive better for backups because it was reading them incorrectly, and I was doing this without the Multimeter which I should of bought. It's one of those Boxes that takes a few seconds afterward to shut off. It's completed Red Ringed, even the Towel Trick doesn't work now. The Second froze when I was playing SFIV with a Friend, days later it worked fine playing Madden. Now it just freezes when it tries to Install Games. I've cleared Cache, and used different HDDs. I recently upgraded to 250GB and this was around the time it happened. I'm just not so sure what to do with these two broken ones anymore. Any ideas? Thanks in Advance.
