pah... when you uninstall a chip you also have to uninstall the new dashboard... the installation is in the HD not in the chip... (you should have done a backup of your original MS dashboard)... to make it work properly without the chip you have to set is IDENTICALY as it was before modding. I don't know about HD locking...
If you have replaced the hd i think you can still use it but you have still to uninstall all functions that works with the chip...
If you want I can give you further details... btw I need help for this stupid chip that goes out of place every fucking time I touch it.
Not true, you can leave them other non MS applications on the hard drive without having the chip in. All you really need to do is lock the hard drive.
From what the original poster has described, I would say that he has fucked up the d0 when hje was removing the original chip.
I would try routing the underside d0 point with the topside then making another connection from the underside d0 to one of the d0 pins on the chip.
