Hi Donald, Were you able to get it working? With the battery disconnected as you describe flashing with the Bus Pirate should work fine. I suspect there must be a bad connection elsewhere.
You might be able to get further assistance on #flashrom on irc.freenode.net .

Something else which just occurred to me:
I used flashrom on the Chromebook itself to program this very same chip in the first place, without the -p option, which I assume defaults to the internal programmer. It worked perfectly. Now that I bricked it somehow, I tried to restore the BIOS image using flashrom and the bus pirate as the programmer. This is the failure whose log I sent you previously.
Any idea why the internal programmer works, but the bus pirate programmer can't recognize the chip?

sudo ./flashrom-0.9.8-r1914 -p buspirate_spi:dev=/dev/ttyUSB0 -r spi.bin -VVV -o log.txt
but no operations are supported because the chip is not recognized. Can you provide any advice on how to move forward?
