"Remove all power and wait" is by far the easiest way to reset a
keyboard, but ...
If one really could not get the keyboard to work, but wanted to upgrade
the firmware anyway, here is a recipe:
a) Get a USB stick, ideally factory-formatted with a FAT filesystem, but
ext2 will work too.
b) Put the firmware file, e.g. q3a15.rom, in the root directory of that
c) Create a file "/boot/olpc.fth" on that stick, containing these two
\ OLPC boot script
The important feature of the first line is that it must begin with the
two-character sequence "backslash space".
d) Insert the stick into the XO and let it auto-boot.
e) When the machine resets after the reflashing, remove the stick
f) Delete or rename the /boot/olpc.fth file so that stick won't cause an
auto-reflash the next time you insert it.
