I just bought a pixel 6 from my friend who said it was normal, but after I turned it on, a fastboot mode error appeared.

and the device state is unlocked with the reason BL1 requested as in the picture, is there any hope for it to return to normal?

I asked in some forums that it is possible that it is normal if the device is unlocked, but is that true? Please help me, my friend
