I have modded alot of xbox system's but this is the 1st time I have ran into this problem. I am modding a 1.6 xbox with the x3 chip. Installation went fine, but I got to the flashing part and my troubles began. I am using X3 3029 v16plus.bin bios. I use FTP flash all goes well, but after it powers off when I try to power it back on with the chip enabled it just shuts right back off. this is my 1st x3 mod by the way. but I followed all the guides I could find and everything went well up to this point.
