Question: why does the xbox boot three times then flash red and green?

[Wekd]

Actually Is there any possible way that I can put back the file
and I'm positively sure that it will work

However I'm still not sure about that chip model
but I'm pretty sure that the person who installed was a professional, because I screwed up myself, and not him

Because I can play copy games before
therefore I was thinking if there is any way, I can put back the file that I deleted before
and everything will be fine again!
