Alright so heres the deal I have a xbox 1.6, possibly now with a 1.7 mobo.Anyways its got a WD 160gb(unlocked) with a X3 and the problem is I was changing the eeprom on his xbox through x3 with a older xbox version(it was a 1.3 I believe) anyways it totally fragged the board and I had to get a new one(the one that i think is a 1.7). I reinstalled the chip on the new board and checked the connections twice now and everything looks ok, but when i boot up i get error 16.The external switches leds aren't working which makes me think that the chips fried,but im not exactly sure what to do. please help or suggest I try something cause im all out of ideas...
