This is my problem:
I had a 1.4 xbox (tsop flashed) but at a time it tried to boot 3 times and then it was shining: red/yellow/red/yellow I think it`s a bad TSOP flash (I had give it to somebody for a day
) I tried to install a DuoX2, but same problem 
The chip is starting when the xbox had already to boot 3 times, strange
WHAT SHOULD I DO NOW

, without the D0 and the BT but same problem same problem, it looks like the xbox STILL is starting from the original bios, I already checked my soldering, or could only be that problem or maybe the motherboard? (I can`t see anything too btw!)PLZ HELP ME, I WANNA XBOX AGAIN
