Yes, definitely the message levels should be adjusted. They’ve changed almost all of these error messages before, but there’s more left, basically everything you commonly see should be an info message - cancellations (due to tail end), successes, notes about node status (or those could be status messages). It should be refactored to be more logically structured. But the text part of the message is good.
Also the download successful entry could be for example “0x3A download successful”, by all means, add codes, just keep the verbose part. Helps everybody, easier to handle by software, easy to be read by less technical humans.
