well i just install my exec 3 chip in when i turn on xbox it just try three times and shut off. The blue light did go on the chip but the xbox won't even goto bios screen. Then i went and put everything back without the mod the xbox won't turn on either. and the eject button light keep flashing red/green. well i got piss and went and grab my homboys' box which is same version and it did exactly the same . now they both won't even turn on at all. any help here would greatly be appreciated .
bad news, you fragged ur box. when u turn them on and it flashes red, there should be a number in the upper right hand corner of the screen. tell me what it is and i'll be able to tell u what u screwed up on.
