One of the problems I encountered was a Xbox 360E Corona v6 with RROD... the code in trouble was 4431 tho a lot of people say it's junk after this code and should be scrapped the one we are talking about is not:) and still working. It got the problem after an RGH, my friend that did the RGH did it for the first time and he bought a kit of Ebay with a solder gun, solder, solder paste, and other bits... to get the story short he had some bad connections on the QSB surrounding the processor which after a couple of days of working like a charm started developing a bad case of the RROD*:).
