    You are entering
    Code (Text):
    1. fastboot boot recovery recovery.img
    When I think what you want is
    Code (Text):
    1.  fastboot flash recovery recovery.img

    If none of that works try Kingroot run it on your phone and it should root it for you

    @lunatic59 Both Yes & No, they may want to:

    fastboot boot recovery.img

    so it'll just boot into the recovery and you can check to make sure it even works, which will also enable other options when booted.
    The cmd:

    fastboot flash recovery recovery.img

    Will indeed install the recovery.img to recovery partition

    Just going off the op's post, which I assume was taken from the rooting instructions. ;)

    Wrong version of fastboot perhaps, or wrong recovery image?

    OP was just a case of extra cmd name when specifically using "boot" vs "flash" in fastboot cmd.. boot is directed at the file in question whereas flash wants a location to write file to
    (how) -> (what) ->(file)
    fastboot boot recovery.img

    (how) > (what)>(where) -->(file)
    fastboot flash recovery recovery.img
