For the moment leave Xbox D0 to ground.
You now need to attend to the LPC soldering as this is the most likely cause of the symtptoms you are getting with D0 grounded. Make sure your BT connection is good then reflow the soldering to the LPC points.
Only put the D0 back onto the chip once the the box is booting to the Flash screen

500+ Duo installs never a faulty one yet for me, but there is always a first time.

If the box still FRAGs (flashes red and green ) with the chip out then the damage is to the D0 point. Check witrh a multimeter for continuity between the top D0 and the underside D0 point.
how do i do that?
im not an expert when it comes to electrotecnic! ...so please forgive me.
--------------------
With the xbox on and the dvd-rom removed ...i measured for a short time (1-2sec.) on both D0 points 3.4volt than the box went off, booted up (again 1-2sec 3.4volt) -- went off, --booted up and than i measured nothing more on both D0 points.
i also checked point 9 and 6 for (3.3volt and 5volt) -->Works!
-->watch video FRAGS and CHIP
i haven't a hunch! what else can i try?
Thanks

Boot the xbox as if you were booting the retail bios. Does it still Frag or does the MS dash come up ok?
If it still frags there may be damage to the D0 point or trace. You can measure with no power on and a multimeter set to continuity or ohms range, between the bottom D0 point and the top one on the motherboard. It should measure short circuit. If it doesn't there is a problem with the D0

D0 must be ok. Time to break out the magnifier and go through the whole area you worked on.

Providing the box booted ok before you attempted the mod then there has to be some damage somewhere.
