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
