Well, raven is the codename for Pixel 6 Pro.
Pixel 6a is bluejay.
How did you end up getting the wrong device name? You won't brick it just
by flashing, I'm just really curious how it can happen.
Maybe you misclicked and downloaded the release just on the bottom of it?
Because raven will appear just under bluejay.
The bootloader should reject wrong images, but it won't specify the reason.
So this is quite safe to try and flashing random stuff on Pixels, they are almost
unbrickable in that term. Can't say this about other non-Google devices really.
