So I already set up my SATA card and took apart the 360. I connected the 360 to the SATA card through a SATA cable and opened up Jungle Flasher. My tutorial said that the next step was to turn on the 360, and I did. It turns on just fine, but in about 3 seconds, the 4 lights flash green for a bit and then I get 2 red flashing lights. I'm completely stumped as I've never even heard of this problem before. I know that when you get 2 red lights on the "left quadrant" it means that the 360 is overheated, but the red lights I get are on the top half (top left and top right lights). All the cables are plugged in correctly, and it's in a well-ventilated area. The 360 did not feel warm at all, either.
