Lots of problems trying to unlock the Bootloader

This E9+ is my fifth device to root, and the first one in which I've encountered issues.
I'm following this guide that is specific for my phone here on xda.
First step is unlocking the bootloader, for which I'm sent to the htcdev website.
First step there is to reboot to Bootloader or on some devices, Download mode. No problem so far.
Next is to select Fastboot. from the menu. There is no Fastboot. Some Google-fu suggests I reboot my phone, go to Settings>Power>Fastboot and check the box. There is no Fastboot in that menu. I also checked in the Developer Tools menu. HTCdev suggests enabling OEM unlocking in the Developers Tools menu, however there is no OEM unlocking in that menu.
I had tried a few other things as well.
Usually rooting is as easy as pie in the sky due to the wealth of information online, but I have been stuck at Step 0 for days now.
If anyone could help, I would greatly appreciate it.

You DON'T select fastboot. fastboot is a command that you enter with a combination of commands to do certain things like flashing the stock rom or a custom recovery.
boot to the bootloader mode
choose download mode
then with the use of fastboot files enter the commands that you need

i am trying to unlock the boot loader of my E9x as well, after choosing boot to download mode, the screen displayed "This build is for development purposes only. Do not distribute outside of HTC without HTC's written permission. Failure to comply may lead to legal action". please help me

Question 'fastboot flashing unlock' just brings up command list instead of unlocking

Hey fam, hope you've been keeping well and safe.
I recently bought the Pixel 6 Pro (so happy with it!) and am currently in the process of rooting it.
It's a fairly simple process, and I've done it with all but I'm not sure what's going wrong at the initial unlocking the bootloader stage.
OEM Unlocking & USB Debugging is enabled - I've tried to deactivate/reactive it, used different ports etc. but to no avail.
It just won't unlock, and instead just gives me prompts of commands.
I've attached the screenshots.
What am I missing/doing wrong? Thanks!

are you in fastboot when you are running these commands? boot into fastboot. type the command ' fastboot --version , what version does it output?
run fastboot devices command so your devices appears, then run the unlock command again. make sure you are you using latest platform-tools (not mininal adb etc). also reinstall the driver just in case. then
you can also just go to Android's Flash Tool to unlock the device:

Thankyou so much for your quick and really helpful reply!
So I've investigated further, and re-installed all the tools/as you mentioned above - still no avail.
There does seem to be some sort of an issue as the fastboot version command responds back with 'version unknown'.
The Android Flash Tool looks like the best solution (didn't even know it existed, so thanks for that!) but I'm unsure how to proceed with it in order to unlock the bootloader (from what I'm gathered you need to have an unlocked bootloader before using it?)
I'm assuming you deselect the 'lock bootloader' option so that the tool unlocks the bootloader and then doesn't relock it? I've attached a screenshot to just check as well.

yeah you need to have OEM Unlocking enabled to use Google's Flash Tool. if you don't need any data, just enable these options in the flash tool: Wipe and Force Flash Partitions. That will unlock the bootloader and wipe/reflash Android. Enabling the "lock bootloader" option will re-lock the bootloader but since you are rooting it, leave it unchecked.
But you should look into why Platform-Tools isn't working on your system. Here are instructions on how to set it up (make sure to remove all other platform-tools)
there's also Nexus Tools from Github (developed my a known tech journalist)

@rajalot besides what @Alekos said, I always go straight to the source for the latest SDK Platform Tools every time I flash anything. Also, Get the Google USB Driver (this is for Windows). Note, a recent experience. I have a Samsung tablet and have the Samsung USB drivers installed. This driver worked perfectly fine for my Pixel 6 Pro too for the last two months, but for June the full factory image would error out trying to flash until I uninstalled Samsung's driver and went back to Google's. So if you have any other device USB drivers installed than Google's, you may have to uninstall those and install Google's.
But yeah, as @Alekos said, the site Official Google Android Flash Tool (OEM Unlocking needs to be toggled on - you may not have to manually unlock the bootloader - the "site" will do that on its own) will get you what you need too although if there's a conflicting driver, you would still have to solve that.

I'm going out on a limb but is this a Verizon p6p?

I hope @rajalot updates us, although they said they did enable OEM Unlocking (and seem to be indicating that they have since re-disabled and re-enabled it, although that can be interpreted differently), which would usually indicate that they're not using a Verizon device. Weird, huh? I'm guessing the Platform Tools version is the culprit, but I'd like to hear back to confirm.

How To Guide Unlock Bootloader on G20 (SPD)

I had to unlock my bootloader on my old but trusty G20, had it grayed out. This is often normal on relatively new android devices. 1. Finish your setup wizzard normally, 2. Connect To Wi-Fi,. 3 Have it grab signal from his rild or modem. 4. Then open developer settings and go on adb shell to type adb shell reboot bootloader... then just type fastboot devices followed by fastboot flashing unlock on your phone press power down and wait (make sure the device does not have FRP set to ON if it´s on boot again and remove your Google´s Account). Done, now you can do a fastboot reboot and finish the setup wizzard again, go into dev settings and you will see "Bootloader is alrredy unlocked". (The order on the steps is key to make it work) reasoning is quite simple, you should not be unlocking a bootloader of a device that you don´t own, hence finishing the propper setup first should give you the best result, set no google acccount and no security (you are going to wipe the device again when you unlock the oem). Just bringing this up if it helps someone unbrick or fix their G20 (good device even for UNISOC).​
