PROBLEM SOLVED:

there was a new Entry in the KIT dropdown: V3 PRO. After a reboot, I got my precious UI back.

Cheers,

You only need:

update_zynthian.sh (once is enough)

Hi!
I have a similar problem too. On new firmware, with all updates. After launch, it displays the zintian logo on the screen indicating the error. None of the settings help solve the problem.
The normal operation of the device is obtained on the firmware “2020-05-27-zynthianos-buster-lite-1.0.0-RC2” without updates. As soon as I launch updates or flash a new image, an error immediately occurs.
The only difference in settings with updates is GPIO Expander set to MCP23008.
And when it works then GPIO Expander is set to MCP23017.
Please, help to use the latest software. =)
