Hey guys, I'm trying to revert from custom pie to stock, without sucess.

This is the info OP requested:
(bootloader) ro.build.fingerprint[0]: motorola/potter_nt/potter_nt:8.1.0
(bootloader) ro.build.fingerprint[1]: /OPS28.85-17-6-2/77e7:user/release

So, I downloaded this firmware "POTTER_RETAIL_8.1.0_OPS28.85-17-6-2_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml".

However, I'm getting error messages all the time, as visible in the prints.

Can anyone help me with this?

The errors on the second screenshot at the bottom (clogo and customize) are totally normal, this is for customizations from Moto maker, you can ignore them. There's another error regarding logo, have you flashed another bootlogo to get rid of the 'the device is not secure' screen?
The rest of the first screen looks pretty normal,not sure what happens on the second screenshot. I'm on mobile now, have to check that at PC for better viewing.Is your device booting into stock? If not what happens (error message)?

Another question, do you use a flashall.bat to make sure you don't have any wrong inputs ?
Here's one for stock Oreo:

Hey, thanks for helping me!

So, I haven't flashed anything besides TWRP and Pixel Experience, so I have no idea why is this error appearing.

And no, the device is not flashing the stock. Whenever I reset my phone, it goes directly to bootloader. When I press "Start", it boots Pixel Experience.

I even tried to use the .bat you sent me, but I got the same results...

Every error message is named " command write failed (no error)".
If you google that you often find that there is an issue with the USB connection. Check your USB ports and the cable, or try another PC.

Also, are you using a Linux distribution or Windows? And what kind of ADB and Fastboot tools?

For flashing oreo you don't need persist backup as there is no problem in oreo. But if you going for nougat then take a back up of Persist, so in case you lost IMEI then you can get back you presist. But for any unknown problem in future it will better to take a back up presist.

Oh okay, I will be going back to Oreo itself. Is it okay to flash the latest Oreo even though I was on the older update when I switched to a custom ROM?

You can flash the latest oreo firmware for your device, it doesn't matter if you go from older to latest, but if you go from latest to older version it will brick your device, so be alert when you download the firmware.

In short terms: Don't downgrade.
Everything else is ok.
