As long as you follow the steps on the HTC website to unlock the bootloader, you should be good to go.I have the said phone model, but the trick is I neve rooted phones before. Can I fck something up, like brick my phone? It's on Nougat android.
Did you try reboot to bootloader or reboot to download?It's what I wanted to do, went to HTC website on steps how to unlock bootloader, this is what first two steps say:

But for me it's different menu after I enter bootloader mode. I have this:

So, fastboot and bootloader options in this mode aren't available at all. I can't progress over step 1 and 2 because of it. I can't highlight Fastboot as it's told in the guide, because it's not there.
Did you try reboot to bootloader or reboot to download?
