LG V20 only access to fastboot

[HKnight]

Hi I've seen threads around that have the same issue is there any help I can get.

I only have access to fastboot
my device will hang on LG logo

I've tried flashing recovery and it won't boot into it

I also tried https://forum.xda-developers.com/showpost.php?p=70393155&postcount=3 and cannot flash misc, fota, but I can flash cache
- the error i get here is " remote: cannot erase this partition in unlocked state "
-- so i locked it with fastboot oem lock and fastboot flash lock and i get the same error with it declaring a " locked state " forcing me to unlock the bootloader again

I've attempted to flash .kdz files with no luck as im in download mode and the guides even say to put in download mode and LGMobile support tool isn't able to detect phone saying it's not even plugged in.
- is there a .dll file or something i need I've read twice in two different post maybe it's typos

I ran LGMobile support tool and it fails after downloading the .kdz file (my guess) not being able to put the phone in download mode is causing it to do so

I'm running out of ideas can anyone help?

update: I managed to get back into twrp by issuing the command -- fastboot flash boot boot.img -- I renamed it boot.img and it worked
update: I'm back now in android after flashing my rom.
