[Moto G5 Plus Questions & Answers] Nivead:
I am not an expert, but this is what you need to do, so you can be helped:

1)	Download minimal_adb_fastboot_v1.4.3_setup.exe to your computer. Install the program on your computer..

https://androidfilehost.com/?fid=746010030569952951

This program is a terminal program that allows the computer to communicate, push and pull files, to android phones.

Insure the phone’s battery is fully charged.

Turn the phone off. Connect a USB cable between the phone and the computer. Press and hold both the VOLUME DOWN key and the POWER key. The Fastboot Flash Mode screen should be displayed. On the computer, execute the MINIMAL ADB FASTBOOT program. Type the following commands in the terminal window:

fastboot devices

The program will respond with the phones serial number and fastboot;

C:\Minimal ADB Fastboot>fastboot devices

serial_number fastboot

C:\Minimal ADB Fastboot

This is a confirmation that the computer is able to communicate with the phone. If you do not see the serial number (this phones serial no. is serial_number), then there is a communication problem between the phone and the computer and you need to troubleshoot the connection and/or drivers.

2).	Type the following commands in the command windows:

Fastboot getvar all

The phone will return a long printout of phone information;

C:\ADB>fastboot getvar all

Look for the strings labeled bootloader ro.build.fingerprint 0 and 1. This important information is the version of the firmware installed on the phone. It is potter:8.1.0/OP28.85-17-6-2 . Record this firmware version for future reference, as you may need to reinstall the original software in the future.

you will need a 8.1 version firmware to obtain an OREO bootloader

Hope that helps
