Hi guys... I'm having the same problem here. I have a 1.6, just installed a Xecuter 3 CE, flashed it with X3 3108plus and all the flashing process went ok. Then when the xbox automatically shuts off I GOT NO VIDEO BUT STILL CAN LISTEN THE AUDIO. I haven't changed any setting (neither video nor nothing else). I also got flashing orange.
If I hold down the power button and disable the chip, eveything boots fine. If I press both buttons, the chip boots to 256kb backup bios.
I have tested using the button sequence that neogoten mentioned but nothing happens. Also I tried to boot holding A + B + X + Y but nothing happens neither.
Any idea please??? I am so desperate... I have two weeks with this problem...
Thanks you a lot...
