I recently flashed my samsung drive to the Xtreme Firmware 5.2 and everything worked fine for around 4 weeks. My 360 then started freezing up and eventually led up to the 3 rings of doom. I then read around the net about using the "towel method." I wrapped a towel completely around my 360 for around 15-20 minutes. Low and behold, my 360 worked again.....for approximately 10-20 minutes, then it started to freeze up and got the red rings again. I repeated the towel method and got my 360 to work again, but the red rings again after 20 minutes of playing. I am wondering if anyone has an idea what exactly should I be looking for after opening my 360 so i can fix the problem. I have great solder skills and just need to know what to look out for inside. My 360 was manufactured 2006-07-11. Thanks for all your assistance.
