Moto G6.
Connected to Win 10 PC , ADB and Fastboot installed.
Boot device into bootloader: adb reboot bootloader - device reboots into bootloader.

Download TWERP (twrp-3.5.1_9-0-ali.img) and moved to same folder as ADB and Fastboot (C:\).
Run fastboot comand:
C:\>fastboot flash recovery twrp-3.5.1_9-0-ali.img
(bootloader) is-logical:recovery: not found
Sending 'recovery' (16196 KB) OKAY [ 1.501s]
Writing 'recovery' (bootloader) Image recovery failed validation
(bootloader) Preflash validation failed
FAILED (remote: '')
fastboot: error: Command failed

What am I doing wrong?

    Moto G6 plus has the recovery partition merged with the boot one. If you want to use TWRP, you have to use the boot command instead, and then flash a TWRP zip installer for this phone.

    Thanks for the reply.
    I am a noob when it comes to this.
    How do I use the "boot" command?

    Type "fastboot boot the-name-of-the-twrp-file.img".

    Also as advice and nothing related, if you want to revert your changes back to stock, don't forget to NEVER RELOCK your bootloader. There's a low chance of getting your phone back fully functional after this mistake.
