*Refusal to update EC code*
When upgrading from old software versions, Open Firmware may refuse to
update the EC firmware, showing a battery icon with a bad face on every
If you can access the ok prompt (bios) you can try "test /battery"
to see if provide more information.
In my xo, with the charger disconnected show:
AC:off Battery: BYD LiFePO4 91% 6.25V -0.58A 22.8C discharging
and with the charger connected show:
AC:on Battery: BYD LiFePO4 91% 7.02V 2.01A 22.8C
Yes.
The "sad face battery" icon has remained a mystery on this laptop. It
refused to update firmware last time I updated as well, but it did boot.
I tried with a different battery and the problem persists.
Thanks
Sebastian

Hello OLPC devs,
I tried to update an XO4 touch to 32016o4.zd. It looked like it went
fine, but...
It won't boot, with the following error (see image attached).
Hints are very welcome. Impatient young one around.
:-)
