Nexus 6P Bootlooping, can't go to recovery mode, tried multiple flashes, used Nexus Root Toolkit. Is my device gone forever?

As you guys may know, the Nexus 6P has a notorious bootlooping issue. After trying multiple flashes, and even going to WugFresh's Nexus Root Toolkit, I had no avail for any signs that my device was fixed. I can't go to recovery mode either because it bootloops there too. My question is that is my device gone forever? Can I no longer fix it? Thanks in advance.
