Issues

upgrade: The device is supported, but the config is incompatible to the new image (1.0->1.1). Please upgrade without keeping config (sysupgrade -n).

FAQ: There's no option in owut to upgrade without keeping the config. I can do it with auc -n, why not owut?

owut download --version-to 24.10.5 --keep
sysupgrade -n /tmp/firmware.bin
