After messing around with the LPC rebuild PCB I eventualy gave up with it as IMO the pads are too large on the underneath and they bridge connections far too easily. Anyways, not a problem I've got some proper PCB jumper wire so I thought I'd desolder the rebuild PCB and do it myself instead... That's when it all went horribly wrong
On removing the rebuild PCB it took two traces with it (which I've repaired, but obviously still with problems...) The d0 trace wasn't a terrible break and just soldering the d0 wire over the break to the via was sufficent to repair it. The second break was *much* more serious... The LAD2 trace lifted completely and broke the via beneath it as well, this was also repaired and seems to be measuring fine with a multimeter.
Now the actual problem
The modchip appears to work just fine, it boots off the main RAM and the backup RAM - the lights all work and the flashBIOS screen doesn't freeze (it connects fine to my network too) but... I can't flash the chip at all - it constantly says that the BIOS is read-only no matter what I do to it (change the switch on the chip itself, change the switch on the switchbank and even remove the switchbank completely). Added to this, I can now no longer get the m$ dashboard to come up. It was coming up fine before I removed the rebuild PCB, but now I get a black screen and a steady green light on the xbox?!?!!! Does this indicate a corrupt m$ BIOS? Any ideas? Any ideas especially for what to look for so I can flash the X3? I don't care much if I haven't got a working m$ dashboard - I'm never going to use Xbox Live... But at the moment, it's just a pretty looking doorstop!
Any help very much appreciated thank you!
