OK , some more progress...we're getting there, with a bit of luck.

After some trial and error (like shutting down the VBox guest Windows OS altogether before trying to run the fastboot command on the host machine) I managed to get this far:

Code:

jpb@amd:~/installs/kindle/fastboot> sudo ./fastboot flash diags mmcblk0p2_ssh.img
downloading 'diags'...
OKAY [  2.112s]
writing 'diags'...
OKAY [  5.799s]
finished. total time: 7.911s

Now restarting the VM and rebooting in diags mode using Mfg Tool, I was able to connect from the host:

Code:

# ssh root@192.168.15.244

Are you sure you want to continue connecting (yes/no)? yes

Rootfs is mounted read-only. Invoke mntroot rw to
switch back to a writable rootfs.
#################################################

At this stage, I have stopped there.

Now what I need to know is whether it is safe to:
- Mount rootfs read-write
- Copy the "forensic" images to their locations using dd

The Kindle has now frozen at the diagnostics screen and I cannot get it to export its USB drive so as to be able to upload the mmc* images. But perhaps that is because it needs some more charging.

So assuming - hopefully - that it just needs to charge and I can then upload the image files, it may be possible to get it back to working order?

Cheers.
