Bro, I think you locked the bootloader without installing the stock ROM. This is baaad. You should have flashed the stock firmware with Odin before locking the bootloader.
Now, I guess you can try booting to download mode, flashing the stock original ROM with odin. Then, if everything works, unlock the bootloader in the normal way and then flash TWRP.
You cannot flash TWRP if your bootloader is locked.

im not allowed to go up or down in the menu, its just stuck.. and if i press power it just reboots into recovery, if i take battery off i can boot back to os (4.0.4) thinking Original owner installed this wrong? Or is this normal stock? again, i just got the phone so not sure.

You can try to unlock the bootloader and flash the factory image. Beware, you'll loose every data in the internal memory.

Thanks, so does this mean this was stock, or no, since i can't move up or down.
Where do i go from here, a how to flash factory image tutorial?
Search the forums. Its all here.
All bootloaders are stock. There are no custom bootloaders/radios.
Cant tell what is on your phone in the bootloader mode. But there is some kind of issue if the volume up and down doesnt work in that mode

Try fastboot oem lock and then fastboot oem unlock that will work!

Pixel 2 Stuck On Bootloader, Can't Boot/Recovery [ERROR: Slot Unbootable: Load Error]

Hey guys! I have a Pixel 2 that basically bricked this morning. When booting only the bootloader comes up. The device can't boot into the OS or even the recovery.
Now I understand the Pixel 2's are dual partition and my "Boot-slot" is "b" not "a". I don't remember changing it though, that is if the factory default is "a". I'm not sure if everything is on "a" and that's why this is happening but I can't switch the boot slot over to "a" through fastboot as "slot change is not allowed in lock state". I did not enable USB Debugging so I can't change Lock State, or at least not that I know of.
Does anyone know how to get this phone back up and running?

Re flash factory image.
You don't need usb debugging for fastboot, only ADB. Unlock your bootloader using fb, then reflash the factory image, as enzyne said. Yeah, when you unlock, you're going to lose everything, as it completely wipes your device, but at least you'll have your phone back.

This unlock method is only applicable to ZUI. If you are in global rom, just simply enable OEM Unlock in Developer Settings, then run this command under bootloader.
Code:
fastboot flashing unlock

Make sure you have enabled OEM unlock in developer options first.
Translated Chinese to English on 2nd screenshot:
Long press volume up to unlock bootloader.
I've enabled it in dev menu so I'll have a look on what u said on the second pic
