we provide an unlocked flash image, but also, of course, don't have
hardware black- or whitelists, and now even suggest to remove the restiction
on original batteries. In another sense, this "unlocks" the device.

this addresses #22 but we could actually build a patched ISO...

how did this end up there?

flashrom might do it anyways, but we have the read image and can
make sure the user didn't by accident provide the other image, for
example.
