Hi again, 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? Thanks, Donald On Thu, Jan 14, 2016 at 10:47 PM, Donald Dade <donald.dade@gmail.com> wrote:

Hi,

I bricked my Chromebook and am trying to recover it.

I'm using:

Ubuntu 15.10 Bus Pirate v3.6 with firmware v6.2 flashrom 0.9.8 r1914

to try to read a:

Windbond 25Q64FV on a Toshiba Chromebook 2 2015 (battery disconnected)

by doing:

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?

Thank you,

Donald
