Hey, If i were to buy a pixel 8 straight from Google, unlock the bootloader, install graphene, lock the bootloader, and then put it under my carrier… would I still be able to use grapheneos? I’m not sure if when T-Mobile carrier locks the bootloader, they also delete any OS that isn’t stock android.
Not an Android pro, just dabble in it, I guess first question is do you mean T-Mobile USA? Second, the phones I have seen that brand themselves on boot (like almost all Samsungs in last 10 years) do so because the hardware maker decided on that function. As I understand it Pixels do not do any such thing. Lastly I have never heard of a carrier that can lock a bootloader. The only carrier I have ever heard of doing any relocking was Sprint USA, and even then they couldn’t actually relock an unlocked phone, so they would report it stolen worldwide and thereafter would only allow activation on their platform (which sounds illegal but they were swallowed by T-Mobile before they got called out on it)
