Solder a link wire from BT to G on the DuoX2 like in this picture ...




You should have D0 from motherboard to D0 on DuoX2






XBOX V1.6

You should NOT have a wire to BT on motherboard ( behind eject button )

Now press power to boot the xbox and the RED led on the DuoX2 chip should flash on and off continuously. If your RED led is not flashing resolder your D0 point and double check it's the right point you have soldered to. Change your D0 to the bottom side one if your using the top D0. If you have a Xbox V1.6 then triple check you have rebuilt the LPC correctly as this is most likely your problem. If you used a LPC REBUILD board then de-solder it and use wires. Use a multimeter to check there is power running throw the LPC. Heres a pic of the LPC pinouts ...




With the xbox on and the dvd-rom removed set your multimeter to volts DC and place the BLACK probe on pin 2 and the RED probe on pin 9, It should read 3.3V. Now move the RED probe to pin 6, It should read 5V. If you don't get power resolder the connections after you turn the xbox off. Also have a look for broken or damaged traces around the LPC points.

If the RED led flashes but the MS BIOS boots then the D0 point is the problem and you will need to resolder it. Try using the bottom side D0 as it's easier. Try booting my HackDaBox Reflash Cd as sometimes people think the chip isn't working becuase the MS dashboard boots but this is normal, it won't look different unless you have installed a replacement dashboard.

Make sure you have plugged the DuoX2 onto the pinheader the right way , here is a picture.





If your chip still won't boot then resolder all the connections and the female headerpin that's attached to the DuoX2 !

Finally if your DuoX2 chip now behaves like it should and boots up fine into the hacked bios and the RED led is flashing then your BT wire was your problem and you can now remove the link from BT to G and now fit a wire from the DuoX2's BT to the BT on the bottom of the motherboard.
