Did you unzip/extract the firmware before uploading?

Happens quite often, seems to be not clear in the description.  
Happy wood chipping!

I think this is a Windows Explorer.exe thing, I’m not aware of being able to access a file within a .zip archive in macOS or, I think Linux. Maybe the Windows instructions need to be touched up for this?

Your right, on my short visit to win10 I noticed that the file browser keeps opening for you to see all files.  
This does not happen with the other 2 candidates.  
If you don’t pay close attention to the tiny zipper or the menu, you hardly get to know that you are viewing the content of a compressed file.
