    So basically I've been using this guide: link, I flash twrp to the device(tried multiple twrp versions):

    PS C:\adb> fastboot flash recovery twrp.img
    target reported max download size of 536870912 bytes
    sending 'recovery' (19744 KB)...
    OKAY [ 0.590s]
    writing 'recovery'...
    OKAY [ 0.186s]
    finished. total time: 0.777s

    Which looks like it works, then I try and boot into the recovery and get this error:

    PS C:\adb> fastboot boot twrp.img
    downloading 'boot.img'...
    OKAY [ 0.589s]
    booting...
    FAILED (remote: unknown command)
    finished. total time: 0.609s

    I have manually entered the recovery menu, but it just factory resets the device instead of booting into twrp (Pressed Y twice on the recovery menu).The device is unlocked, and using android 7.0.1

    PS C:\adb> fastboot getvar unlocked
    unlocked: yes
    finished. total time: 0.007s

    Any ideas?

    That "tried multiple twrp versions" bothers me. Have you tried the latest version for the 850 from https://twrp.me/lg/lgg5h830.html (not for another G5)? If there were problems with it, we would have been hearing screams for a while. The current version should be twrp-3.2.2-0-h830.img dated June 30, 2018.

    Have you read Team Win's writeup on it?

    Oh, and that's not how you "boot into recovery".

    fastboot flash recovery twrp.img
    fastboot reboot

    Then you should be in TWRP.
