you are funny to blame the chip when you admit to a half-assed job being the problem. the chip is probably still fine and it is your install that is the issue

I did offer you advice. I said your install is to blame, so redo your install. If you installed it correctly and your chip was toast, you would be getting a frag and not your system starting fine but the chip not coming on.
Use your brain and think "If I installed it correctly it would be booting off the LPC" If it was booting the LPC with a bad chip it would frag. If it is booting like the chip is not even there then your install is no good. Check your DO and your work on the LPC.

Ground the Xbox D0 if the retail bios still boots the D0 is not as good as you think

Even when I short the m/board d0 to a ground (I used a metal circle around a screw hole?) it still just boots to the standard xBox "enter time & date" screen..

Your soldering to the D0 is not correct then

I would suggest taking it to a pro. It may seem like good soldering, but it is obviosuly not.

You are one step nearer now. You now confirmed the D0 is working.
nect thing is to check out if BT is working or not.
Connect a wire link from BT on the chip to pin 9 (point G). Plug in the chip and make sure your now working D0 is connected to the chip D0. Boot the box from the power button and report what is the symptom

Well the D0 is now working as without the chip on and the D0 grounded the box FRAGs
Putting the link wire in sets the chip to always on.
You have in that case most likely fried the chip when you first attempted the mod.
At this point you need to try another chip to prove it beyond any doubt

OK. Thanks for the help Chancer. I thought as much!

Julius Pleaser · « **Reply #8 on:** August 24, 2006, 05:26:00 AM »

Your symptom is due to poor soldering. Your D0 seems to be ok so it is most likely on the LPC that is the issue.

Some images of the carnage I have wrought...

Topside of lpc: lpc top

topside d0: topside d0

Bottom of lpc: LPC bottom

Anyone see anything terminal there?

you need to step away from the solering iron

the d0 looks like its gone
and you are missing a lpc ring

appleguru · « **Reply #11 on:** August 24, 2006, 08:58:00 PM »

Not only is that lpc ring gone.. looks like you ripped up the whole trace as well

Chancer · « **Reply #12 on:** August 25, 2006, 05:04:00 AM »

The box needs to go to someone who can solder correctly. You have trashed some of the connections on the board and are on your second chip. The pictures make it clear your soldering iron is not powerful enough at all .
Take the box somewhere and get it sorted before its too late

Chancer · « **Reply #13 on:** August 25, 2006, 08:57:00 AM »

Top D0 is done for. this a thorugh PCB connection and although part of the silver is there, you must have severed the through PCB connection

Navillos · « **Reply #14 on:** August 25, 2006, 09:37:00 AM »

you just need to wick the d0 point hole with solder and it should boot. no maybe someone else should wick it
