Failed to patch OTA zip

[hereblur]

I cannot patch the OTA. Is this my device not supported?

avbroot ota patch --input ota-9.zip --key-avb avb/avb1.key --key-ota avb/ota1.key --cert-ota avb/ota1.crt --rootless

I also tried

$ avbroot ota extract -i ota-9.zip -d extracted -a

Thanks for the logs and the OTA link. Unfortunately, your device won't work with avbroot because it uses AVB 1.0 instead of AVB 2.0.
