[Moto G5 Plus Questions & Answers] Glencoe:
I am from Canada, and my carrier is Videotron, though we bougth the (unlocked) phone from Target, in the US, so I'd think the channel may be RetUS indeed.

I should have mentioned I had already tried it, and it didn't work indeed. Just checked again, and all it says is "Failed to match the connected device..."

I followed your guide (my, I realise you are a guru on here!), and tried flashing with mfastboot (while sending each system.img chunck separately, as I have 8 system.img_sparsechunck.* files)... Looks like it failed again!

This is what I get from the Command prompt:

I will try to uninstall all drivers and try again, just in case, but if you see anything else, let me know! I really appreciate your help!
