This might be helpful for anyone attempting the OS install who maybe isn't particularly familiar with the underlying tech involved (my first encounter with smartphonery btw - I'll be retiring next year ;) ). Normally, anything at all to do with Google is strictly banned from my kit - the purchase & install was therefore always going to be stressy.
I was stuck for some while at the stage of getting the install-ware to recognise the device, blocked at Fastboot Mode, Device State 'locked' (in green). Both installation modes had been attempted: web USB and command-line. The config:
- Operating system Windows 10 21h2; memory & disk space not an issue.
- Device is Pixel 8 OEM-unlocked enabled, in Fastboot Mode
- Cable used new USB-C to USB-C - it works (e.g. to charge the device); I'd tried an alternative (new) USB-A to USB-C, no difference.
- Fastboot package version: 35.0.2; verified in PowerShell (not downloaded from Graphene site - anomalies with cURL in PowerShell would not handle the link).
Web-USB attempt: 'no device connected'; it was. Then, command-line attempt: command to unlock bootloader (.\fastboot flashing unlock) hangs ... 'waiting for device to be connected'; it was already. Windows sees Pixel 8 in Device Manager, but there were no compatible drivers recognised ('not installed' Code 28) nor available for the device. So necessary to locate, download & unzip usb_driver_r13-windows online.

DM still not impressed by what was available at first, but a second try got a viable driver recognised. Now it worked, into Fastboot Mode: Device State 'locked' (in green), 'unlockable' (in red).
That wasn't the last obstacle. I couldn't get PowerShell to obtain the factory images as the command prompt started asking for 'Uri' input (eh ? cURL didn't much run as expected at all, but then I'm not weapons-grade with PowerShell ...). However, it was possible, now that the bootloader was unlocked, to switch methods at mid-point and revert to web-USB install for the rest - which worked swimmingly.
Just need a Pixel screen keyboard now with broad enough special-character range to cope with the router password requirements and I'll be surfing. Hope this is a time-saver for some ...
