I think you are not trying exactly what others are advising you should do, you are in your own trying things out of scope. The links for TWRP are very clear in the various guides provided by VD171.I tried that too with no avail.
Then I got a link from someone to an official TWRP for merlin (from twrp.me) but it was for Motorola Moto G Turbo, also named merlin.
Now not even the hardware buttons work, so I'll take it to a support store, and I hope they can fix it.
Thank you for your support
The better is using simply the SP Flash tool with your device completely off, READ the thread to bypass the EDL authorization and all will be OK, recover first the ability to boot and after try again to customize it always that you didn't have a mistake and flashed something for other device that worst the things what I'm starting to suspect.
