I have just finished installing my x3 into my v1 xbox with the pro3switch but the following problems have arisen. When I hold the power on button for more than 1 second (disable x3) the hard drive fails to boot xbox screen and defaults back to enabled x3. Finally when I hit both power and eject button the switch does not shine purple but only blue. Anyone know where or what pins I should be checking and also is it safe to run a continuity test with my multimeter to check for cold joints (concern here is putting current on the board. Thanks for help on any of the above.
