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

[Wekd]

About that thread
I already read that post

However this is the situation that happens to me
I went to Flash Bios ---> Evox 6.1
and accidently, I delete evox 6.1
and everything just doesn't work anymore
The screen didn't show up
There was no sound
Everything suddenly didn't work

I would like to know how can I repair it
Right now, I can't even connect X-box to Comp
therefore is there any possibility that I can repair it
If it does, can anyone help me out
Thank you
