Hi again,

I notice the following in the log:

1. Redémarrer is not automatically recognised a a restart word so that was fixed.
2. your system did not produce an event in the event log marking the system shutdown before the system started shutting down, but it was recorded after system shutdown had initiated, but it was logged as an event containing invalid XML. Can you please look through the event viewer (sort for system event 1074) for the event which occurred at about 17:31:53 and paste the XML here?
   

Nevertheless...

3. The app did correctly try to power off the TV both when fastboot was enabled and disabled. However it failed to do so when fastboot was disabled. (From the log: "Retried twice but failed to perform work of type 2. Aborting!")

I don't see how #3 is related to fastboot specifically. Howewver I have seen the issue pop up intermittently and it seems to be related to webos23 potentially - it seems sometimes the TV refuses connections. To resolve this issue you should probably choose to use "persistent connection" or "persistent connection + keep alive" in the device configuration

Hi, here the requested logs:

at 17:28:40: https://pastebin.com/7c1qjavy
at 17:30:36: https://pastebin.com/88CNsiqW
and at 17:42:01: https://pastebin.com/zWeL4D8q

Note: With "persistent connection + keep alive" the screen power off as intended both with and without fastboot enabled!

Thanks you!
