My Cerbo GX with guimods only shows white screen after firmware update

My Cerbo GX with guimods only shows white screen after firmware update.

All consoles show the same problem (via LAN, VRM-Portal and HDMI-Output).

I tried uninstalling SetupHelper as shown in kwindrems documentation on github but no joy.

The device is still updating the vrm portal.

My next idea would be a serial cable to get onto the console. I am a linux expert, so I am confident to resolve the problem via console.

I would try to boot the previous firmware.

I did not find information on how to switch boot partitions via terminal though.

What should I do to revert to the last used firmware?

Alternatively I would line to know how to do a blind „full install“ via USB/SD card.


Many thanks in advance,

Oliver

/opt/victronenergy/swupdate-scripts/scan-versions.sh

checks which versions are available.

/opt/victronenergy/swupdate-scripts/set-version.sh 2

will switch it.
