Grounding the d0 causes the box to boot from the LPC, but the chip isnt 'enabled' so it still frags. Connect the d0 wire to the chip where it is supposed to be, then jumper the BT pad on the chip to pin 9 on the chip. I am almost positive just grounding the d0 does not work with a duox2.
This advice is spot on.
Some of the lite + GS chips boot without anything on BT but can boot unreliably leaving a signal line disconnected. The earlier Duo chips do not enable with BT left off no matter what you are told . I have tried it many time before whilst experimenting with different set ups.
So follow the advice of StrictPuppet and you will be fine.

Not a good idea leaving BT floating, but it is your choice.
The earlier DuoX 2 as stated do not boot with BT left disconnected. Even if you have the later GS or Lite (as previously stated) I would connect BT to pin 9 for long term stability and reliable boot.
