Oh okay, thanks. For me, I didn't dare continue, googling it, it wasn't clear if the flashing would be successful, so I switched to Emma on Windows and bat file.

I was then curious reading your guide afterwards (great guide btw) about the error you saw, as useful to know if I want to flash a Nougat image in the future, whether flashtool actually works with the error I saw, "reset-non-secure-adb". It will be interesting to see if anyone else sees it and tries to continue and flash.
