I had a friend install executer 2 mod chip on my xbox a while ago (it's not the first version of xbox, but I believe its the second). Now when I turn on the xbox, there is a error message "16 service required" then a bunch of other languages. Also the LCD would flash red and green and my mod chip light would be red instead of green. I checked to see if the chip was lose but it seems fine (no matter how i position it, the lights on the chip are blue and ones yellow, while the chip light on the outside is still red instead of green). I asked a friend that had his xbox modded and he said it usually means the chip is lose, but I dont think it is. Any suggestions on a solution?
