I bought a new Pixel 7a in a German "Media Markt", not via carrier, bought it directly cash.
I can't enable OEM Bootloader unlocking, started it up, did initial setup, connected it to wifi, enabled developer options, and waited for two hours.
Internet connection is working fine. Did a factory reset, repeated the process, still can't enable OEM Bootloader unlocking.
I bought a Pixel 6a in the same store an didn't have any problems flashing grapheneos using the official guide.
Do you have any recommendations what I could try to do ? I bought the 7a only for the purpose to flash grapheneos.
