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

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

Now press power to boot the xbox and the RED led should flash on and off continuously. If your RED light 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. 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 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.

Finally if your DuoX2 chip now behaves like it should and boots up fine into the hacked bios and flashed a RED led 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 BT to the BT on the motherboard ( behind the eject button ) or the alternate BT point on the bottom side of the motherboard.

Make sure you have plugged the DuoX2 onto the pinheader the right way !

The bank switch should be close to the left side of the xbox !

if your chip still won't boot then resolder the female headerpin thats attached to the DuoX2 !

Thanks for the link. I made the flash/cd but for some reason my box keeps booting into the M$ bios. My light on the doux2 is flashing red so it should be working right. I bought it from craxtion and it is supposed to have the cromwell bios. I am supposed to flash bank one with the flashbios cd right. When I boot the box the chip flashes red but it never goes to the blue screen, but it goes to the M$ screen instead. Any ideas would be helpful, also I hope this is the right place for this question, if not please move to the appro place.

Is your "BT" wire correctly installed. I did a flawless install in about 5 minutes, but my box kept booting to the MS dash.

After about 6 times, I double checked everything. Solder joints were very clean and everything was routed correctly. . . except for the BT. Instead of soldering it to the top left point on the eject/power assembly, I soldered it to the bottom left. I'm glad it wasn't a more serious error.

Oh. . . and thanks to HackDaBox. This thread helped me out a bit.

Yes I checked the bt point, thanks for the advice though. I have started another thread for my problem.
